Description
The present application is a divisional application of an invention patent application "vehicular lamp and control method thereof" filed on 2016, 12, and 6, and filed under application No. 201611107868.7.
Technical Field
The present invention relates to a vehicle lamp and a control method thereof, and more particularly, to a vehicle lamp and a control method thereof, which can inform a traveling direction of a vehicle to surrounding vehicles or pedestrians by forming a road surface pattern for displaying the traveling direction of the vehicle around the vehicle.
Background
In general, a vehicle has a lamp having the following functions: an illumination function for allowing an object located around the vehicle to be easily confirmed during night driving; and a signal function for informing other vehicles or road users of the driving state of the vehicle.
For example, headlamps, fog lamps, and the like are mainly used for illumination purposes, and turn signal lamps, backup lamps, brake lamps, Side Marker lamps (Side markers), and the like are mainly used for signaling purposes.
The turn signal indicator is provided in front of or behind the vehicle, and is used to indicate the turning direction of the vehicle to other vehicles or pedestrians by flashing when the vehicle makes a change in the traveling direction of the vehicle, such as a left turn, a right turn, or a lane change, at a point such as a crossroad, and to indicate the situation where the vehicle has moved backward to other vehicles by illuminating the backup lamp when the vehicle moves backward.
In this case, even when the turn signal indicator blinks to indicate the turning direction of the vehicle, it is difficult for another vehicle that is oncoming from the turning direction or is in an adjacent position to recognize the turning direction, and even when the backup light is turned on to indicate the backward movement of the vehicle, it is difficult for another vehicle located on the side of the vehicle to recognize the backward movement.
Therefore, there is a need to propose a technical solution to make it easy to recognize a situation even in a case where it is difficult for a driver of another vehicle to easily recognize the blinking of the turn signal indicator lamp or the lighting of the backup lamp.

In the drawings illustrating the present invention, the respective components may be illustrated in a somewhat enlarged or reduced form in consideration of convenience of explanation.
Hereinafter, the present invention will be described by referring to the drawings for describing a vehicle lamp and a control method thereof according to an embodiment of the present invention.
Fig. 1 is a schematic view showing a lamp for a vehicle according to an embodiment of the present invention.
Referring to fig. 1, a lamp 1 for a vehicle according to an embodiment of the present invention may include a traveling direction sensing part 100, a traveling direction display part 200, and a control part 300.
The traveling direction sensing part 100 may sense a turning direction of the vehicle, a traveling direction of the vehicle such as forward or backward, and in an embodiment of the present invention, the turning direction of the vehicle may include: left or right turns, driving lane changes, head drops, etc., at points such as intersections.
The traveling direction sensing part 100 may sense forward or backward movement of the vehicle through a gear, etc., and may sense a turning direction of the vehicle through a rotation angle of a steering wheel or wheels, an operation of a driver, lane sensing, etc.
The traveling direction display unit 200 is provided at least on one side of the front or rear of the vehicle, and can display the traveling direction of the vehicle.
For example, the traveling direction display part 200 may be disposed at both sides of the front or rear of the vehicle when displaying the turning direction of the vehicle, and the traveling direction display part 200 may be disposed at both sides of the rear of the vehicle when displaying the backward movement of the vehicle.
Also, the traveling direction display portion 200 may be provided to display the turning direction and the reverse of the vehicle, respectively, and may also be shared as follows: either the turning direction or the backward movement of the vehicle is displayed according to the traveling direction of the vehicle.
Fig. 2 is a schematic view illustrating a traveling direction display part according to a first embodiment of the present invention.
Referring to fig. 2, a traveling direction display part 200 according to a first embodiment of the present invention can display a turning direction of a vehicle, and a case where the traveling direction display part 200 is disposed at a side of a headlamp 10 of the vehicle to display the turning direction of the vehicle is explained in fig. 2 as an example.
In this case, the traveling direction display unit 200 may be provided on both sides of the front or rear of the vehicle, fig. 2 shows an example of the case where it is provided on either side of the front of the vehicle, and the remaining elements may be configured to be the same with some differences in installation position, direction, and the like.
The traveling direction display part 200 according to the first embodiment of the present invention may include the first lamp module 210 and the second lamp module 220, and the case where the first lamp module 210 and the second lamp module 220 are disposed in the up-down direction is illustrated in fig. 2 as an example, but is not limited thereto, and the disposition direction of the first lamp module 210 and the second lamp module 220 may be variously changed according to the arrangement pattern of the vehicle lamp 1.
As shown in fig. 3, the first lamp module 210 of the traveling direction display part 200 according to the first embodiment of the present invention forms a blinking pattern P1 that blinks when the vehicle travels while turning left or right at a point such as a crossroad or the like or changes a driving lane; the second lamp module 220 may form a road surface pattern P2 by cooperating with the first lamp module 210, the road surface pattern P2 displaying a turning direction of the vehicle on a road surface around the vehicle when the first lamp module 210 is operated.
At this time, in fig. 3, the case where the road surface pattern P2 includes the plurality of light irradiation patterns P21, P22, P23 has been described as an example, but not limited thereto, and the road surface pattern P2 may include a single light irradiation pattern as shown in fig. 4.
In the first embodiment of the present invention, since both the first lamp module 210 and the second lamp module 220 function to display the turning direction of the vehicle, it is necessary to irradiate the same color of light, and for this reason, the first lamp module 210 and the second lamp module 220 preferably share the same lens (e.g., outer lens).
In the first embodiment of the invention, a case where the first luminaire module 210 and the second luminaire module 220 share the same lens is taken as an example for description, but not limited thereto, and the first luminaire module 210 and the second luminaire module 220 may also have lenses with the same color.
In other words, the vehicle lamp 1 according to the present invention may be provided with not only the traveling direction display unit 200 but also a plurality of lamps (e.g., headlamps, position lights, etc.) used for various purposes in a plurality of spaces defined by each other, and the lenses may be formed as follows: the lenses respectively corresponding to the plurality of spaces demarcated from each other are integrally formed by a double injection molding process.
In this case, when the installation distance between the first lamp module 210 and the second lamp module 220 is relatively large, the lenses of the first lamp module 210 and the second lamp module 220 need to be formed separately, and thus, the number of lens manufacturing processes or assembling processes may increase.
Therefore, in the first embodiment of the present invention, in order to prevent the quality of the exterior design of the vehicle lamp 1 of the present invention from being degraded and to achieve the convenience of the injection molding, assembly, or manufacturing process of the lens, it is preferable that the first lamp module 210 and the second lamp module 220 are provided in the space corresponding to the same lens with the installation pitch within 75 mm.
At this time, since the traveling direction display part 200 according to the first embodiment of the present invention displays the turning direction of the vehicle, it may be disposed in a space corresponding to a lens mainly having a yellow-series color, but is not limited thereto, and a transparent lens having a color required by the light itself irradiated by the first and second lamp modules 210 and 220 may be used.
Also, the first and second luminaire modules 210 and 220 are disposed adjacent to each other to enable shared use of the same lens, which is advantageous. To this end, the first and second luminaire modules 210 and 220 may be disposed together on a common substrate, or the first and second luminaire modules 210 and 220 may be arranged within the same luminaire housing.
For example, the first luminaire module 210 and the second luminaire module 220 may be disposed together on the common substrate 200a as shown in fig. 5 and 6, and in fig. 5 and 6, a case where the first luminaire module 210 includes the light source 210a and the reflector 210b and the second luminaire module 220 also includes the light source 220a and the reflector 220b is described as an example, but the reflectors 210b and 220b may be omitted for the direct light type luminaire.
In this case, in fig. 5 and 6, the light source 220a and the reflector 220b of the second lamp module 220 are included in any one of a plurality of light source units 221, 222, and 223 included in the second lamp module 220, which will be described later, and the remaining elements may be configured to be the same only in terms of installation position, installation direction, and the like.
Further, as is apparent from fig. 5 and 6, the first and second lamp modules 210 and 220 are not arranged on the same line but arranged along the vertical or horizontal direction, and the purpose thereof is to prevent interference of light caused by light irradiated from each other while the respective lamp modules 210 and 220 perform functions.
As described above, in the case where the first and second lamp modules 210 and 220 are provided on the common substrate 200a, the structure can be simplified and the cost can be saved.
In the first embodiment of the present invention, the case where the plurality of light irradiation patterns P21, P22, P23 are located on a straight line extending in a predetermined direction from the vehicle has been described as an example, but is not limited thereto, and the arrangement direction of the plurality of light irradiation patterns P21, P22, P23 may be variously changed.
The flicker pattern 1 and the road surface pattern P2 are formed when it is desired to change the traveling direction of the vehicle, such as when changing the lane of travel as shown in fig. 7 and 8, or making a left or right turn on a crossroad as shown in fig. 9, or when the vehicle enters from a parking lot as shown in fig. 10, and serve to display the traveling direction of the vehicle to other oncoming vehicles or pedestrians in the turning direction of the vehicle.
In this case, fig. 8 illustrates an example of a case where a plurality of vehicles traveling on different lanes change lanes to the same lane, and in this case, the plurality of vehicles that want to change lanes to the same lane form the road surface pattern P2, respectively, so that the drivers of the respective vehicles can recognize surrounding vehicles changing lanes to the same lane, thereby preventing a vehicle accident.
Also, in the first embodiment of the present invention, the plurality of light irradiation patterns P21, P22, P23 may have the same or different sizes or shapes.
For example, in the foregoing fig. 3, the case where the plurality of light irradiation patterns P21, P22, and P23 have the same size is exemplified, but not limited thereto, and the plurality of light irradiation patterns P21, P22, and P23 may have different sizes from each other as shown in fig. 11.
At this time, in the foregoing first embodiment, the description has been given taking the case of displaying the traveling direction by means of the traveling direction display sections 200 provided on either one of both sides in front of the vehicle as an example, but the flicker pattern P1 and the road surface pattern P2 as in the foregoing first embodiment may be formed by at least one of the traveling direction display sections 200 provided on both sides in front of or behind the vehicle, respectively, according to the traveling direction of the vehicle.
Referring again to fig. 2, in the first embodiment of the present invention, the second lamp module 220 may include a plurality of light source parts 221, 222, 223 such that a plurality of light irradiation patterns P21, P22, P23 are formed, and the plurality of light source parts 221, 222, 223 may include the light source 220a and the reflector 220b as shown in fig. 5 and 6, respectively.
The plurality of light source units 221, 222, 223 may be disposed at different heights or angles according to the formation position of each light irradiation pattern.
For example, the light source for forming the light irradiation pattern closest to the vehicle among the plurality of light source parts 221, 222, 223 may be disposed at the lowest height from the ground or at the largest angle of the optical axis with the ground, and the light source for forming the light irradiation pattern at the farthest position from the vehicle may be disposed at the highest position from the ground or at the smallest angle of the optical axis with the ground.
Here, since the plurality of light irradiation patterns P21, P22, P23 are formed in the first embodiment of the present invention, the plurality of light source sections 221, 222, 223 are used, and the number of light source sections for forming the light irradiation patterns may also be different according to the number of light irradiation patterns.
The second lamp module 220 according to the first embodiment of the present invention has left and right light irradiation angles preset with reference to a center line of the vehicle, and may have up and down light irradiation angles preset with reference to a road surface.
The second lamp module 220 may have a left and right light irradiation angle of 0 to 45 degrees, and may have an up and down light irradiation angle of 5 to 60 degrees.
Hereinafter, in the first embodiment of the present invention, a case where the left and right light irradiation angles of the second lamp module 220 are 20 to 45 degrees and the up and down light irradiation angles are 15 to 45 degrees will be described as an example.
In the first embodiment of the present invention, the left and right illumination angles of the second lamp module 220 are set to 20 to 45 degrees, and the up and down illumination angles are set to 15 to 45 degrees, because the visual confirmation of surrounding vehicles or pedestrians is considered.
For example, as shown in fig. 12, when the vehicle is traveling at a point such as a crossroad in an attempt to turn right, a flicker pattern P1 is formed and instantly flickers by the first lamp module 210 of the traveling direction display section 200 provided on the right side in front of the vehicle, and at the same time, a road surface pattern P2 is formed by the second lamp module 220 in the following manner: the road surface pattern P2 is formed at a predetermined right and left light irradiation angle θ 1 with respect to the center line C of the vehicle by taking into account the maximum turning angle at which the vehicle can turn.
At this time, if the left-right light irradiation angle θ 1 of the road surface pattern P2 with the center line C of the vehicle is less than 20 degrees, since it is similar to the lane of the road, there is a disadvantage that it is difficult to recognize the directivity of the road surface pattern P2 when the surrounding vehicle or pedestrian who is coming from the right-turn lane observes the road surface pattern P2 from the side of the vehicle, as shown in fig. 13, so in order to ensure the visual confirmation of the road surface pattern P2 to the surrounding vehicle or pedestrian, it is preferable to form the road surface pattern P2 to have the left-right light irradiation angle θ 1 of more than 20 degrees from the center line C of the vehicle.
Further, when the steering wheel of the vehicle is turned to the maximum, the rotation angle of the vehicle wheels is 30 to 40 degrees, so the left and right light irradiation angle θ 1 is preferably smaller than 45 degrees which is a limit of the vehicle's rotation, and if the left and right light irradiation angle θ 1 of the road surface pattern P2 is larger than 45 degrees, the road surface pattern P2 may be blocked by an obstacle (for example, a building, a vehicle, or the like) located adjacent to the vehicle as shown in fig. 14, and if a large vehicle is parked around as shown in the aforementioned fig. 10, since the road surface pattern P2 is formed in the vehicle parked around, it is difficult to inform the surrounding vehicle, a pedestrian, or the like of the traveling direction of the vehicle, so the left and right light irradiation angle θ 1 of the road surface pattern P2 and the center line C of the vehicle is preferably 20 to 45 degrees.
Further, as shown in fig. 8, when a plurality of vehicles traveling in different lanes change the traveling lane to the same lane, it is necessary to make the right and left light irradiation angle θ 1 formed by the road surface pattern P2 and the center line C of the vehicle smaller than 45 degrees in consideration of the viewing angle of each vehicle driver, so that the operation of changing to the same traveling lane can be easily recognized.
The left and right light irradiation angles θ 1 of the second lamp module 220 in the foregoing first embodiment are exemplified to facilitate understanding of the present invention, and the present invention is not limited thereto, and the second lamp module 220 may have a light irradiation angle of 0 to 45 degrees according to road environments such as a kind of a road, a lane width, a position of an obstacle, and as an example, the second lamp module 220 may have various left and right light irradiation angles θ 1 of 0 to 45 degrees, 5 to 45 degrees, 10 to 45 degrees, or 20 to 45 degrees according to road environments.
In this case, the left-right light irradiation angle θ 1 of the second lamp film 0 is made larger than 0 degrees in order to prevent the following: when two vehicles form the road surface pattern P2, respectively, if the left-right light irradiation angle θ 1 is smaller than 0 degrees, the road surface pattern P2 is irradiated toward the vehicle inside, so that it is impossible to figure out which of the adjacent two vehicles forms the road surface pattern P2.
Further, when the vehicle travels and departs while staying near the road boundary line, the road surface pattern P2 may be formed on or beyond the road center line depending on the situation, and in this case, it may be difficult for surrounding vehicles or pedestrians to recognize which vehicle is going to depart, and therefore, as shown in fig. 15, the center portion CP of the road surface pattern P2 is preferably formed at a position within a distance range of 2.7m to 3m from an axis passing through the front end of the vehicle and perpendicularly intersecting the longitudinal direction of the vehicle to form the center line CL.
Here, the reason why the center portion CP of the road surface pattern P2 is formed at a position within a range of 2.7m to 3m from an axis passing through a front end of the vehicle and perpendicularly intersecting with a longitudinal direction of the vehicle is that the distance at which the center portion CP of the road surface pattern P2 is located may become different when the vehicle width of the vehicle becomes different because the minimum vehicle width of the vehicle is generally 2.7m to 3 m.
Fig. 15 is an example of a case where the road surface pattern P2 includes a single light irradiation pattern, and is similarly applied to a case where the road surface pattern P2 includes a plurality of light irradiation patterns.
Therefore, in the first embodiment of the present invention, the left and right light irradiation angle θ 1 of the second lamp module 220 is made to have 20 to 45 degrees, so that, as shown in fig. 16, when a surrounding vehicle or a pedestrian coming in the turning direction of the vehicle views the road surface pattern P2 from the side of the vehicle, the directivity of the road surface pattern P2 can be easily recognized, and it is possible to prevent a situation in which the road surface pattern P2 is blocked by an obstacle or the like and the surrounding vehicle or pedestrian cannot recognize the road surface pattern P2 from occurring.
In addition, in the first embodiment of the present invention, the upper and lower illumination angles of the second lamp module 220 having 15 to 45 degrees means that the angles θ 21, θ 22, θ 23 formed by the optical axes of the respective light source sections among the plurality of light source sections 221, 222, 223 and the road surface, which have been already explained as shown in fig. 16, have 15 to 45 degrees, and can be understood as meaning: an angle formed by the optical axis of the light source forming the light irradiation pattern at the position closest to the vehicle and the ground is less than 45 degrees, and an angle formed by the optical axis of the light source forming the light irradiation pattern at the position farthest from the vehicle and the ground is more than 15 degrees.
At this time, in the first embodiment of the present invention, since the flicker pattern P1 formed by the first lamp module 210 irradiates light to about 10 degrees in the vertical direction as shown in fig. 17, it is preferable that the second lamp module 220 has the vertical light irradiation angles θ 21, θ 22, and θ 23 larger than 15 degrees with an interval of about 5 degrees so as to prevent light interference with the first lamp module 210.
Also, when the second lamp module 220 irradiates at the upper and lower light irradiation angles θ 21, θ 22, θ 23 larger than 45 degrees, the irradiation of light may be limited by a structure such as a front or rear bumper of the vehicle or a housing in the lamp, and thus the upper and lower light irradiation angles θ 21, θ 22, θ 23 preferably have an angle smaller than 45 degrees.
In addition, when the second lamp module 220 irradiates at the up-down light irradiation angles θ 21, θ 22, θ 23 larger than 45 degrees, the road surface pattern P2 is formed at a position very close to the vehicle, so that it is difficult for surrounding vehicles or pedestrians to recognize the traveling direction of the vehicle, and therefore, the up-down light irradiation angles θ 21, θ 22, θ 23 preferably have angles smaller than 45 degrees.
In the first embodiment described above, the vertical light irradiation angles θ 21, θ 22, θ 23 of the second lamp module 220 may be variously changed according to the angle formed in the vertical direction by the flicker pattern P1 formed by the first lamp module 210, the structure of a structure such as a front or rear bumper of the vehicle or a housing in the lamp, and the like, and the vertical light irradiation angles θ 21, θ 22, θ 23 of the second lamp module 220 are not limited to 15 to 45 degrees, and the vertical light irradiation angles θ 21, θ 22, θ 23 of the second lamp module 220 may be variously changed to 5 to 60 degrees, 10 to 55 degrees, 15 to 45 degrees, and the like.
Therefore, in the first embodiment of the present invention, the left-right light irradiation angle of the second lamp module 220 is set to 20 to 45 degrees, and the up-down light irradiation angle is set to 15 to 45 degrees, so that it is possible to make it easy for surrounding vehicles or pedestrians to recognize the turning direction of the vehicle through the road surface pattern P2 and take countermeasures.
With the aforementioned traveling direction display section 200 according to the first embodiment, the illuminance of the second luminaire module 220 may be equal to or higher than that of the first luminaire module 210, because the second luminaire module 220 needs to irradiate light relatively far from the vehicle, and therefore if the second luminaire module 220 has an illuminance lower than that of the first luminaire module 210, it is difficult to obtain sufficient luminance as the road surface pattern P2.
In the first embodiment of the present invention, the second luminaire module 220 preferably has a luminance of 4,300 to 13,000cd because the surrounding environment such as the surrounding luminance is taken into consideration.
For example, when the vehicle needs to display the traveling direction of the vehicle by the road surface pattern P2 due to a reduction in the field of vision (i.e., at the evening), the illuminance of the road is substantially 100lux with reference to natural lighting, and here, the illuminance at the evening is determined as the brightest condition among the conditions required for the road surface pattern P2, and in this condition, the road surface pattern P2 needs to have at least a luminance of 200lux or more in order for the road surface pattern P2 to have sufficient visual confirmation to be distinguished from the surrounding road surface, and therefore, the second lamp module 220 preferably has a luminance at least higher than 4,300 cd.
For example, when considering a standard illuminance reference of an underground parking lot or a street lamp, the illuminance of a road, i.e., a road surface is approximately 100lux at the maximum, and in this case, in order to make the road surface pattern P2 have sufficient visual confirmation to be distinguished from the surrounding road surface, it is preferable to have a luminance of at least 200lux or more.
Here, the second lamp module 220 has a luminous intensity at least higher than 4,300cd, which means that the illuminance of the light irradiation pattern formed farthest from the vehicle is at least 200lux or more.
For example, if light is irradiated at the same illuminance on a road surface at a distance maximally far away, in this case, if light is irradiated at a 15-degree vertical light irradiation angle from 1200mm, which is the maximum height of the travel direction display unit 220, the distance from the travel direction display unit 220 to the road surface is substantially 4636mm, and at this distance, the minimum illuminance (the value obtained by multiplying the illuminance by the square of the distance (m)) for providing the illuminance of 200lux or more needs to have a value substantially higher than 4,300 cd.
Here, the maximum height of the traveling direction display unit 200 may be an installation height of a light source unit disposed at the highest position among the plurality of light source units 221, 222, 223 included in the traveling direction display unit 220, and may be an installation height of the third light source unit 223 in the first embodiment of the present invention. The reason why the maximum height of the travel direction display unit 220 is set to 1200mm is that if the height of the travel direction display unit 220 is set to more than 1200mm, the display will be out of the driver's view and the visibility will be reduced.
Further, in the case where the illuminance of the second lamp module 220 is high, the road surface pattern P2 reflects to make surrounding vehicles or pedestrians feel dazzling (Glare), and therefore the second lamp module 220 preferably has an illuminance lower than 13,000 cd. For example, light reflected by a road in rainy weather may be glaring to surrounding vehicles or pedestrians, so to prevent this, it would be advantageous for the second luminaire module 220 to have a luminosity lower than 13,000 cd.
The foregoing first embodiment has been described taking as an example the case where the illuminance of the second lamp module 220 is 4,300cd to 13,000cd, but this is merely an example for facilitating understanding of the present invention, and the present invention is not limited thereto, and when the second lamp module 220 includes the plurality of light source sections 221, 222, 223 so that the road surface pattern P2 includes the plurality of light irradiation patterns P21, P22, P23, it is advantageous that the difference between the minimum illuminance and the maximum illuminance is smaller in order to prevent a reduction in the appearance quality, because if the difference in the illuminance of light generated from each of the light source sections 221, 222, 223 is larger, the illuminance of light is not uniform when the vehicle lamp 1 is viewed from the outside, resulting in a reduction in the appearance quality.
Therefore, in order to provide sufficient visual confirmation of the road surface pattern P2 while preventing dazzling of surrounding vehicles or pedestrians, and also to prevent the quality of the appearance of the vehicle lamp 1 from being degraded, it would be advantageous to have a luminous intensity of 5,000cd to 10,000cd, and more preferably 5,500cd to 8,500 cd.
The first embodiment described above is a case where the traveling direction display unit 200 displays the turning direction of the vehicle, and the following is considered as a case where the traveling direction display unit 200 displays the backward movement of the vehicle.
Fig. 18 is a schematic view illustrating a traveling direction display part according to a second embodiment of the present invention.
Referring to fig. 18, the traveling direction display part 200 according to the second embodiment of the present invention may display the backward movement of the vehicle, and in the second embodiment of the present invention, a case where the traveling direction display parts 200 are respectively disposed at both sides of the rear of the vehicle to display the backward movement of the vehicle will be described as an example.
The traveling direction display part 200 according to the second embodiment of the present invention may be disposed at one side of the tail lamp 20 of the vehicle, and may include a first lamp module 230 and a second lamp module 240 similarly to the aforementioned first embodiment. At this time, in fig. 18, a case where the first lamp module 230 and the second lamp module 240 are disposed in the left-right direction is exemplified, but not limited thereto, and the disposed direction of the first lamp module 230 and the second lamp module 240 may be different according to the arrangement pattern of the vehicular lamp 1 or the like.
As shown in fig. 19, when the vehicle backs up at a parking lot or the like, the traveling direction display unit 200 according to the second embodiment of the present invention lights up the first lamp module 230 to form a lighting pattern P3, and the second lamp module 240 may form a road surface pattern P4 for displaying the back-up of the vehicle in cooperation with the first lamp module 230.
In the second embodiment of the present invention, the case where the road surface pattern P4 includes the plurality of light irradiation patterns P41, P42, P43 formed by the plurality of light source sections 241, 242, 243 included in the second luminaire module 240 is exemplified, however, not limited thereto, and as shown in fig. 20, the road surface pattern P4 may include a single light irradiation pattern.
In the second embodiment of the present invention, the first and second luminaire modules 230 and 240 are preferably disposed within 75mm in such a manner that the same lens can be shared for reasons similar to those of the foregoing first embodiment, the road surface pattern P4 formed by the second luminaire module 240 may include at least one light irradiation pattern, and the number of light sources for forming the light irradiation pattern may also be different according to the number of light irradiation patterns included in the road surface pattern P4.
That is, the traveling direction display unit 200 according to the second embodiment of the present invention is provided at the rear of the vehicle, and not only the traveling direction display unit 200 but also a plurality of lamps (for example, a tail lamp, a stop lamp, a position light, etc.) used for various purposes may be provided at the rear of the vehicle in a plurality of spaces defined by each other, and the first lamp module 230 and the second lamp module 240 may be provided together in any one of the plurality of spaces defined by each other, thereby sharing the same lens.
In the second embodiment of the present invention, a case where the first luminaire module 230 and the second luminaire module 240 share the same lens is taken as an example for description, but not limited thereto, the first luminaire module 230 and the second luminaire module 240 may also have lenses with the same color.
In the second embodiment of the present invention, since the traveling direction display unit 200 displays the backward movement of the vehicle, a lens having a color such as white, blue, or yellow may be mainly used, but not limited thereto, and a transparent lens having a color required by the light itself irradiated by the first lamp module 230 and the second lamp module 240 may be used.
In addition, in the second embodiment of the present invention, the first and second lamp modules 230 and 240 may be disposed on a common substrate similarly to the aforementioned fig. 5 and 6, in which case, the structure may be simplified and the cost may be saved.
Here, as is apparent from fig. 19 and 20, the road surface pattern P4 is formed by the traveling direction display units 200 provided on both sides of the vehicle behind, and the purpose of this is to make it easy for another vehicle approaching from the left or right side to recognize the vehicle as backing when the vehicle backs up at a parking lot or the like, as shown in fig. 21.
Fig. 21 shows an example of a case where a large vehicle is parked around, and in this case, even if another vehicle cannot see the vehicle, the other vehicle can recognize the vehicle by the road surface pattern P4 and take measures in advance.
In the second embodiment of the invention, the road surface patterns P4 may be arrayed at predetermined intervals on a straight line extending in a predetermined direction from the vehicle similarly to the road surface patterns P2 of the foregoing first embodiment, however, not limited thereto, and the array direction may be variously changed.
Further, in fig. 19, the case where the light irradiation patterns P41, P42, and P43 of the road surface pattern P4 for displaying the backward movement of the vehicle have the same size was described as an example, but not limited thereto, and as shown in fig. 22, the light irradiation patterns P41, P42, and P43 may have not only different sizes but also different or different shapes.
In the second embodiment of the present invention, the second lamp module 240 preferably has a luminous intensity of 4,300 to 13,000cd for reasons similar to those of the foregoing first embodiment, and as shown in fig. 23 and 24, the left and right light irradiation angles θ 3 are preferably 20 to 45 degrees, and the up and down light irradiation angles θ 41, θ 42, θ 43 are preferably 15 to 45 degrees.
Here, the right and left light irradiation angle θ 3 of the second lamp module 240 in the second embodiment of the present invention is 20 to 45 degrees because the up and down light irradiation angles θ 41, θ 42, θ 43 are 15 to 45 degrees in consideration of the visibility of the surrounding vehicle or pedestrian based on the rotatable range of the vehicle, the obstacle located adjacent to the vehicle, the size of the surrounding vehicle, etc. similarly to the aforementioned first embodiment, and it is an object that, as shown in fig. 25, since the light of the light irradiation region of the first lamp module 230 is irradiated about 10 degrees in the up and down direction, an interval of about 5 degrees is left to have an angle larger than 15 degrees to prevent the interference of the light from occurring, and is configured to be smaller than 45 degrees, thereby preventing the irradiation of the light from being restricted due to a structure such as a bumper or a lamp inner case in front or rear of the vehicle, and forming a road surface pattern P4 at a position very close to the vehicle, thereby preventing the occurrence of a situation in which it is difficult to recognize the traveling direction of the vehicle.
That is, in the second embodiment of the present invention, if the left and right light irradiation angle θ 3 of the second luminaire module 240 is less than 20 degrees, it is difficult to recognize the directivity of the road surface pattern P4 when surrounding vehicles or pedestrians look out of the road surface pattern P4 from the side of the vehicle, because it is similar to the lane of the road; if the left and right light irradiation angle θ 3 of the second lamp module 240 is greater than 45 degrees, the road surface pattern P4 may be blocked by an obstacle located close to the vehicle, and as shown in the aforementioned fig. 21, when a large vehicle is parked around, if the left and right light irradiation angle θ 3 of the road surface pattern P4 is greater than 45 degrees, it is difficult to inform the surrounding vehicle, pedestrians, or the like of the traveling direction of the vehicle, and thus the angle formed by the road surface pattern P4 and the center line C of the vehicle is preferably 20 to 45 degrees.
In the second embodiment of the present invention, the second lamp module 240 has a luminous intensity of 4,300 to 13,000cd, and the left and right light irradiation angles θ 3 are 20 to 45 degrees and the up and down light irradiation angles θ 41, θ 42, θ 43 are 15 to 45 degrees as shown in fig. 23 and 24, but not limited thereto, and the second lamp module 240 may have various left and right light irradiation angles θ 3 of 0 to 45 degrees, 5 to 45 degrees, 10 to 45 degrees, 20 to 45 degrees, and the like, and may have various up and down light irradiation angles θ 41, θ 42, θ 43 of 5 to 60 degrees, 10 to 55 degrees, 15 to 45 degrees, and the like, for the similar reason to the first embodiment.
Moreover, in the second embodiment of the invention, in order to provide sufficient visual confirmation to the road surface pattern P4 while preventing dazzling of surrounding vehicles or pedestrians, and also in order to prevent the quality of appearance of the vehicular lamp 1 from being degraded, it is advantageous for the second lamp module 240 to have a luminous intensity of 5,000cd to 10,000cd, and more preferably 5,500cd to 8,500 cd.
Further, when the vehicle departs by reversing while staying near the road boundary line, the road surface pattern P4 may be formed on or beyond the road center line depending on the situation, and in this case, it may be difficult for surrounding vehicles or pedestrians to recognize which vehicle is going to depart, and therefore, as shown in fig. 26, the center portion CP of the road surface pattern P4 is preferably formed within a distance range of 2.7 to 3m from an axis passing through the rear end of the vehicle and perpendicularly intersecting the longitudinal direction of the vehicle to form the road center line CL.
Here, forming the center portion CP of the road surface pattern P4 at a position within a range of 2.7 to 3m from an axis passing through a rear end of the vehicle and perpendicularly intersecting with a longitudinal direction of the vehicle is because the minimum vehicle width of the vehicle is generally 2.7 to 3m, and in a case where the vehicle widths of the vehicles become different, the distance at which the center portion CP of the road surface pattern P4 is located may become different.
Fig. 26 is an example of the case where the road surface pattern P4 includes a single light irradiation pattern, and the same applies to the case where the road surface pattern P4 includes a plurality of light irradiation patterns.
In addition, in the second embodiment of the present invention, the second luminaire module 240 preferably has a luminance equal to or higher than that of the first luminaire module 230 for the following reasons: the second lamp module 240 needs to irradiate light to a relatively far place from the vehicle, and thus if the second lamp module 240 has a lower luminous intensity than the first lamp module 230, it is difficult to obtain a sufficient luminance as the road surface pattern P4.
Also, in the second embodiment of the present invention, similarly to the aforementioned first embodiment, in order to be able to have sufficient visual confirmation when the illuminance of the road surface by the underground parking lot or the road street light is 100lux at the maximum, the second lamp module 240 preferably has a luminous intensity higher than 4,300cd to have an illuminance of 200lux, and preferably has a luminous intensity lower than 13,000cd in order to prevent dazzling of surrounding vehicles, pedestrians, or the like.
In the first and second embodiments described above, the case where the traveling direction display unit 200 displays the turning direction and the reverse movement of the vehicle has been described separately, but this is merely an example to facilitate understanding of the present invention, and the traveling direction display unit 200 provided at least one side of the front or the rear of the vehicle may be provided to display the turning direction and the reverse movement of the vehicle together.
For example, the traveling direction display units 200 provided on both sides of the rear of the vehicle may be commonly used to display the turning direction and the backward movement of the vehicle together.
Referring again to fig. 1, the control part 300 according to the embodiment of the present invention controls the traveling direction display part 200 based on the sensing result of the traveling direction sensing part 100, so that the turning direction or the reverse of the vehicle can be displayed.
In the embodiment of the present invention, the control unit 300 may cause the first lamp modules 210 and 230 and the corresponding second lamp modules 220 and 240 included in the traveling direction display unit 200 of the first and second embodiments to be interlocked with each other, and the following cases are taken as examples in the embodiment of the present invention: the traveling direction sensing part 100 senses the operation of the turn signal switch as a turn signal of the vehicle and senses the reverse gear R as the reverse of the vehicle, and the control part 300 operates the first lamp module 210, 230 and the second lamp module 240 together according to the sensing result.
For example, when the controller 300 senses the turning direction or the backward movement of the vehicle, the first lamp modules 210 and 230 and the corresponding second lamp modules 220 and 240 may be simultaneously turned on or off, and when a failure is sensed in the first lamp modules 210 and 230 and at least one light source included in the first lamp modules 210 and 230 is turned off due to the failure or the like, the controller may turn off the second lamp modules 220 and 240 together.
At this time, the control unit 300 may simultaneously light or maintain the blinking state of the patterns caused by the first lamp modules 210 and 230 and the corresponding second lamp modules 220 and 240 included in the traveling direction display unit 200 according to the first and second embodiments, or may maintain at least one of the light states and the other light state.
Further, the controller 300 may sequentially form the plurality of light irradiation patterns P21, P22, and P23 and/or P41, P42, and P43 from a position close to the vehicle to a position far away from the vehicle in order to improve the recognition of the traveling direction when the second lamp modules 220 and 240 are turned on.
For example, when the turning direction of the vehicle is displayed by the traveling direction display section 200 as in the foregoing first embodiment, the control section 300 may sequentially form patterns from the light irradiation pattern P21 close to the vehicle to the light irradiation pattern P23 far from the vehicle, as shown in fig. 27.
Also, when the backward movement of the vehicle is displayed by the traveling direction display section 200 as in the foregoing second embodiment, the control section 300 may sequentially pattern from the light irradiation pattern P41 close to the vehicle to the light irradiation pattern P43 far from the vehicle, as shown in fig. 28.
At this time, when the road surface patterns P2 and P4 are formed as described above, the controller 300 can adjust the illuminance of the second lamp modules 220 and 240 according to the ambient brightness.
For example, in the first and second embodiments, the case where the second lamp modules 220 and 240 have the luminance of 4,300 to 13,000cd is taken as an example for description, but the control part 300 may adjust the intensity of the current supplied to the second lamp modules 220 and 240 according to the sensing result of the illuminance sensor or the like, thereby adjusting the illuminance of the second lamp modules 220 and 240.
In addition, the road surface patterns P2, P4 according to the foregoing embodiment are formed up to a predetermined distance from the vehicle, and therefore the road surface patterns P2, P4 may be formed on the surrounding vehicle when the surrounding vehicle is present, so that the vehicle lamp 1 according to another embodiment of the present invention, as shown in fig. 29, includes the traveling direction sensing portion 100, the traveling direction display portion 200, and the control portion 300, and at the same time, may further include the surrounding vehicle sensing portion 400.
In another embodiment of the present invention, the traveling direction sensing part 100, the traveling direction display part 200, and the control part 300 are the same as those of fig. 1, and thus detailed descriptions thereof are omitted.
In another embodiment of the present invention, the surrounding vehicle sensing part 400 may sense a surrounding vehicle through various sensors such as an infrared sensor, an ultrasonic sensor, a radar, etc., and may sense whether or not a surrounding vehicle exists within a distance from the vehicle to a point where the road surface patterns P2, P4 are formed, and the control part 300 may turn off at least one of the plurality of light sources 221, 222, 223 and/or 241, 242, 243 included in the second lamp modules 220, 240, respectively, according to the position of the surrounding vehicle when sensing the surrounding vehicle.
For example, when the turning direction of the vehicle is displayed as in the traveling direction display unit 200 of the first embodiment, as shown in fig. 30, when the surrounding vehicle is present within the distance formed by the road surface pattern P2, at least one of the plurality of light sources 221, 222, 223 of the second lamp module 220 may be turned off, thereby removing at least a portion of the road surface pattern P2.
When the backward movement of the vehicle is displayed as in the traveling direction display unit 200 of the second embodiment, as shown in fig. 31, when a surrounding vehicle is present within a distance where the road surface pattern P4 is formed, at least a part of the road surface pattern P4 can be removed by turning off at least one of the plurality of light sources 241, 242, 243 of the second lamp module 240.
Fig. 32 is a sequence diagram showing a control method of a vehicle lamp according to an embodiment of the present invention, and fig. 32 is an example of a case where a road surface pattern is formed according to a turning direction of a vehicle by the traveling direction display portion 200 according to the aforementioned first embodiment.
Referring to fig. 32, the control method of the vehicle lamp according to the embodiment of the present invention first senses a turning direction of the vehicle (S110). Here, the turning direction of the vehicle is understood to be a direction in which the vehicle turns left, right, or changes a driving lane at a point such as a crossroad.
A flickering pattern P1 is formed by the first lamp module 210 according to the sensed traveling direction of the vehicle, and a road surface pattern P2 is formed around the vehicle, i.e., at least one side of the front or rear of the vehicle, by the second lamp module 220 having higher illuminance than the first lamp module 210 (S120).
At this time, the second lamp module 220 for forming the road surface pattern P2 showing the turning direction of the vehicle may have the left and right light irradiation angles of 20 to 45 degrees as described above, and have the up and down light irradiation angles of 15 to 45 degrees.
Also, the second luminaire module 220 may have a luminance of 4,300 to 13,000cd by considering ambient luminance and the like.
