Description
Technical Field
The utility model belongs to the vehicle illumination field, concretely relates to head-light and a distance light integration lighting system and provide the lighting method of passing light and distance light thereof.
Background
Headlamps, also called headlamps, are mounted on both sides of the head of a vehicle, such as an automobile, for night lighting. Since the lighting effect of the headlamps directly affects the operation and traffic safety of night driving, the traffic control departments in all countries of the world often stipulate the lighting standards in the form of laws. With the continuous development of the technology, the incandescent vacuum lamp is eliminated successively in the past, and the existing automobile headlamp mainly adopts a halogen lamp and a xenon lamp.
Vehicle headlamps, such as automobile headlamps, have unique light distribution structures, and may be classified into high beams and low beams according to the type of light emitted. For example, the light emitted from the high beam is reflected by the reflector and then directly emitted forward to form the "high beam". The light emitted by the low-beam light is blocked to the upper half part of the lampshade reflector by the shading plate, and the reflected light rays are downwards diffused to the ground to form low-beam light, so that dazzling of drivers on opposite vehicles is avoided.
The distribution of the illumination of the low beam by the headlamps is very strict, for example, when the low beam is driven to the right, as shown in fig. 1A and 1B, according to some light distribution standards, when the headlamps are in a low beam mode, on a vertical light distribution screen, a bright area below a h-h' line needs to reach certain light intensity, a dark area is above HH on the left side, B50L is the eye position of a vehicle driver 50 meters on the opposite lane, the requirement is below 650cd, the glare caused by overhigh light intensity is avoided, and a main illumination area is below HH on the left side. The right side is inclined 15 degrees, or inclined 45 degrees to the horizontal vertical line with the distance of 25cm from the turning horizontal broken line HH → HH1 → H1H2 → H2H4 is provided with a dark area above and a side high illumination area and a main illumination area below. The high illumination area beside the right side provides right road illumination and road sign illumination for a driver, and simultaneously sets the maximum light intensity requirement of a BR point, so that traffic safety accidents caused by dazzling of pedestrians close to vehicles are avoided.
As a novel light source, the LED has many advantages which other lighting sources do not have, such as low voltage, long service life, small volume, light weight, fast response, no radiation, no pollution and various severe conditions resistance, and the LED has the advantages that the light emitting direction is one-sided (the traditional light source is 360 degrees of the volume), the collection and utilization of light rays are facilitated, the light utilization rate is improved, and the like. Therefore, it is a new trend to manufacture LED headlamps with LEDs as light sources, but the existing LEDs have low luminous flux, and must increase current to increase luminous flux, resulting in large heat generation, large heat dissipation volume, and reduced lifetime. LED dipped headlight is already in use in the market at present, but LED luminous flux is not enough, and in order to reach the standard, the brightness of middle zone is high, and left and right sides luminance obviously descends a lot, causes the driver visual width to be narrow. Meanwhile, the brightness of the HID headlamp on the market is brighter than that of the LED headlamp, many automobile manufacturers are reluctant to reduce the brightness requirement and select the LED headlamp, and unless the LED headlamp can reach the brightness level of the HID headlamp and the power consumption is lower than that of the HID headlamp and is not more than 25W, therefore, the LED headlamp needs to completely replace the HID headlamp, the brightness, the power, the heat dissipation, the total luminous flux of the LED and an optical system need to be optimized, and the existing optical system is difficult to meet the requirement.
Fig. 2 is a schematic structural diagram of a conventional LED high-beam and low-beam integrated system, which includes an ellipsoidal reflector 201, a shading screen 202, and a lens 203, and it has two focal points F1 and F2 according to the geometric characteristics of an ellipsoid. The LED light source is placed on one of the focus points F1, the light beam emitted by the LED light source is reflected by the ellipsoid reflector 1 and is converged on the other focus point F2, the second focus point of the ellipsoid is just the focus point of the lens, and according to the properties of the lens, the light emitted from the focus point is refracted by the lens, and the output light is parallel light. According to the principle, the shape of the ellipsoid or the shape of the lens 203 can be appropriately changed according to the requirement, so as to horizontally diffuse the light from the lens, then the light shielding screen 202 is arranged at the focus of the lens, so as to form a dipped headlight with a horizontal line inclined upwards by 45 degrees to a horizontal vertical line which is 25cm away from the horizontal direction and a cut-off line of the dark and dark of the horizontal line at the other side, and the light of the ellipsoid of the LED module at the lower part passes through the focus of the lens 203 to form a high beam by removing the light shielding screen. The traditional LED headlamp adopts an ellipsoid, only one LED module can be placed at a focus F1, the luminous flux of one LED module is less, and in order to improve the luminous flux, the LED current must be improved, so that the traditional LED headlamp has the disadvantages of large heat productivity, large heat dissipation volume and shortened service life. Meanwhile, the LED is horizontally arranged in the middle up and down, heat needs to pass through a small middle heat sheet and then is diffused to an external heat radiation body, and the heat radiation effect is poor; the electromagnetic valve is adopted to remove the shading screen, and the electromagnetic valve is mechanical in movement, large in size, heavy in benzene weight and large in power consumption.
As the structure schematic diagram of the LED high beam and low beam integrated system that fig. 3 shows, it includes passing lamp LED301, high beam LED302, passing lamp grading lens 303, passing lamp grading lens 304 etc, LED301 light is direct to form the passing lamp of bilateral symmetry facula through passing lamp grading lens 303, LED302 light is direct to assemble through passing lamp grading lens 304 and forms the high beam facula, grading lens light cornerite is little, the light outside the cornerite is all shielded extravagantly, light utilization rate is low, and can't do left driving rule, or the passing lamp of right driving rule.
Fig. 4 is a schematic structural diagram of a turtle-back-shaped reflector LED high-low beam integrated system, which includes a low beam LED401, a high beam LED402, a low beam reflector 403, a high beam reflector 404, a condenser lens 405, a low beam stop line light-shielding plate 406, and a heat sink 407. The LEDs are arranged close to the heat radiation body 407 from top to bottom, so that heat radiation is facilitated; the light of the LED401 is reflected by the reflector 403 and refracted by the condenser lens 405, and the light above the cut-off line is shielded by the cut-off line light shielding plate 406 to form a dipped headlight light spot. The LED402 is reflected to the focus of the condenser lens 405 by the reflector 404, and then refracted by the condenser lens to form high beam light spots. The LED of the optical system can only adopt one LED module, the total luminous flux of the LED is limited, the size of the LED is limited, the light wrap angle of the reflector is small, light except the wrap angle cannot be collected and utilized, and the light utilization rate is low.
Fig. 5 is a schematic structural diagram of a clam-shaped reflector LED high-low beam integrated system, which includes 5 LEDs 501 for low beam, 3 LEDs 502 for high beam, a low beam reflector 503, a high beam reflector 504, a condenser lens 505, a low beam stop line light shielding plate 506, and a heat sink 507. The LED total luminous flux is improved and the heat dissipation is facilitated by adopting a plurality of scattered LEDs, but one rotating clam-shaped reflector only corresponds to one LED, so that the number of the LEDs is limited, the surfaces of the clam-shaped reflectors corresponding to each LED are few, most of the surfaces are cut off, and the light utilization rate is medium.
Fig. 6 shows a schematic structural diagram of a TIR lens LED dipped headlight system, which includes 10 LEDs 601, 10 TIR assemblies 602, a condenser lens 603, a light shielding plate 604 and a heat radiator 605. By adopting a plurality of dispersed LEDs, the total luminous flux of the LEDs is improved, the heat dissipation is facilitated, the LED light is collimated by TIR, then is converged at the focus of the condensing lens by different TIR surface inclination angles, and is refracted and converged by the condensing lens 603, and the light above the cut-off line is shielded by the light shielding plate 604 to form a dipped headlight light spot. However, the virtual focus of the TIR lens LED dipped headlight system converged to the condenser lens 603 is large, and light far from the ground cannot be concentrated intensively, so that excessive ground near-field light causes waste.
As shown in fig. 7A, the high beam ECE R122 regulation specifies the brightness requirement on the horizontal line of the test point, but does not specify the upper limit of the brightness of the anti-glare area in the local area on the horizontal line, so that drivers of opposite vehicles and pedestrians on the road are dazzled, and traffic accidents are caused. In order to solve the dazzling problem of the high beam, the matrix high beam is applied to the current market, the positions of vehicles and pedestrians in front of the vehicles are collected through the sensor, the single-point LEDs in the corresponding positions are closed, the corresponding positions of the vehicles and the pedestrians form dark spaces, and the anti-dazzling purpose is achieved.

the light L emitted by the linear light source 11 includes a first portion of light L1 and a second portion of light L2, the first portion of light L1 passes through the light reflected by the light reflecting device 70 to the condensing lens 13 for refraction, the second portion of light L2 directly penetrates the condensing lens 13 for refraction, and finally a near light spot is formed.
Further, the method for illuminating the low beam light continues to comprise the steps of:
the light above the cut-off line is shielded by the cut-off line shielding sheet 14 after the first part of the light L1 is reflected by the light reflecting device 70.
Further, in the low beam lighting method, the light reflecting surface of the first light reflecting device 70 is coated with a light reflecting layer, thereby improving the light reflecting efficiency of the first light reflecting device 70. The material of the reflective coating of the reflective surface can be selected according to different use requirements, such as a metal coating, an alloy coating or a composite coating, and the reflective device 70 can also be an integral structure.
