The terminology used in the description of the luminaire herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the present application. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1 to 3, a luminaire 10 of an embodiment includes a lens 100 and a light source 200. The relative position of the lens and the light source is continuously adjustable. The light emitted by the light source is emitted out through the light emitting surface of the lens. The light emitting surface is provided with a maximum light emitting angle position and a minimum light emitting angle position. As shown in fig. 4, when the light source is at the maximum light-emitting angle position, that is, when the maximum light-emitting angle position corresponds to the light source, the luminaire has the maximum light-emitting angle. As shown in fig. 6, when the light source is at the minimum light-emitting angle position, that is, when the minimum light-emitting angle position corresponds to the light source, the luminaire has the minimum light-emitting angle.

In the embodiment, the light emitting surface 102 of the lens faces the light source, the lens 100 covers the light source 200, and the light emitted from the light source 200 can be refracted out through the lens 100. The relative position of the light source 200 and the lens 100 is adjustable. In one embodiment, light fixture 10 is a garden light.

According to the lamp, the light emitted by the light source is emitted through the light emitting surface of the lens, the relative positions of the lens and the light source are continuously adjustable, so that different positions of the light emitting surface of the lens can be adjusted to correspond to the light source, different light emitting requirements of the lamp are realized, and when the maximum light emitting angle position corresponds to the light source, the light emitting angle of the lamp is maximum. When the minimum light-emitting angle position corresponds to the light source, the light-emitting angle of the lamp is minimum, so that stepless adjustment of the lamp in the range of the maximum light-emitting angle and the minimum light-emitting angle is realized, adjustment of any target position in the adjustable position range can be adapted, and stepless adjustment of light distribution of the lamp is realized.

In order to make the relative position of the lens and the light source continuously adjustable, in one embodiment, the lamp further comprises a driving mechanism 430 and a driving shaft 600, the power output end of the driving mechanism is connected with the driving shaft, and the driving shaft is further connected with the lens. The driving mechanism drives the lens to move relative to the light source through the driving shaft, so that the relative position of the lens and the light source is continuously adjustable.

It will be appreciated that the drive shaft may drive the lens to move or rotate relative to the light source, such that the relative position of the lens and the light source is continuously adjustable. In this embodiment, a drive shaft drives the lens to rotate relative to the light source. In one embodiment, the driving mechanism drives the lens to rotate relative to the light source through the driving shaft, so that the rotation angle position of the lens relative to the light source is continuously adjustable.

In one embodiment, the lamp further comprises a control unit, and the control unit is respectively connected with the illuminance acquisition probe, the light intensity acquisition probe and the control end of the driving mechanism. The control unit controls the driving mechanism to drive the lens to move relative to the light source through the driving shaft. The control unit controls the driving mechanism to drive the lens to move relative to the light source according to the illumination and light intensity requirements of the environment and the data of the current illumination and light intensity acquired by the illumination acquisition probe and the light intensity acquisition probe, so that the lamp accurately meets the light emitting requirements.

As shown in fig. 1, in one embodiment, the lens includes a lens unit 110 corresponding to the light source and a holder 120. The light emergent surface is arranged on the lens unit. The holder is connected with the lens unit and the driving shaft, respectively, so that the driving shaft is connected with the lens. In this embodiment, the drive shaft is connected to the lens by a mount. Since the relative position of the lens unit 110 and the light source 200 is adjustable, the light source 200 can be adjusted to different relative positions with respect to the lens unit 110.

As shown in fig. 2, in one embodiment, the light emitting surface 102 includes a first light emitting surface 112 and a second light emitting surface 114, the first light emitting surface is disposed on one surface of the lens unit, a normal cross section of the first light emitting surface is a first arc line 112a, the first light emitting surface is a light emitting groove structure, and the light emitting groove structure faces the light source. As shown in fig. 2 and 3, the normal cross section is a normal plane perpendicular to the position adjustment direction of the lens unit 110, that is, the normal cross section is a cross section perpendicular to the position adjustment direction of the lens unit 110. In the present embodiment, the relative positions of the lens unit 110 and the light source 200 are adjusted by rotation. It is understood that in other embodiments, the relative positions of the lens unit 110 and the light source 200 can be adjusted by means of translation. The first arc line 112a has different shapes for the normal cross sections at different positions of the first light emitting surface.

As shown in fig. 2 and 3, in one embodiment, the second light emitting surface is disposed on a surface of the lens unit departing from the first light emitting surface. In this embodiment, the second light emitting surface is disposed on a surface of the lens unit 110 away from the surface having the light emitting groove 112. The second light emitting surface corresponds to the first light emitting surface, and a normal cross section of the second light emitting surface is a second arc line 114 a. The relative positions of the first arc-shaped line and the second arc-shaped line are different at different normal cross-sectional positions of the lens unit so as to form different light-emitting angles. The shapes of the second arc lines 114a are different for the normal cross sections of the second light emitting surface 114 at different positions.

Since the light exit groove 112 is formed on one side of the light transmitting unit, the light exit groove 112 faces the light source 200, the inner wall of the light exit groove 112 is a first light exit surface, the surface of the lens unit 110 away from the light exit groove 112 is a second light exit surface 114, and the second light exit surface 114 corresponds to the first light exit surface, light emitted by the light source 200 can be refracted by the first light exit surface and the second light exit surface 114 in sequence to be emitted, so that the light emission of the lamp 10 is realized. Because the relative positions of the first arc-shaped line 112a and the second arc-shaped line 114a are different at different normal cross-sectional positions of the lens unit 110, the light source 200 is refracted out through the inner wall positions of the light-emitting grooves 112 corresponding to the different normal cross-sectional positions to form different light-emitting angles, so that when the lens unit 110 is adjusted to different positions relative to the light source 200 along the position adjusting direction, the light-emitting angles of the light source 200 are different, thereby realizing different light-emitting angle adjustment of the lamp 10, so as to meet different light distribution angle requirements, avoiding the requirement that the traditional lamp 10 realizes different light distribution angles by replacing different secondary lenses 100, and solving the problems of high cost and low timeliness of the mold.

In one embodiment, the extending direction of the light exit groove 112 coincides with the position adjusting direction of the lens unit 110, so that the lens unit 110 can be adjusted to different positions corresponding to the light source 200 along the position adjusting direction, and thus the light source 200 refracts different light rays through different positions of the lens unit 110, and the continuity of the light exit of the lens unit 110 is realized. In one embodiment, the extending direction of the light exit groove 112 is a curved direction. In the present embodiment, the extending direction of the light exit groove 112 is an arc direction, i.e., a circular arc direction in which the light exit groove 112 extends along the circumferential direction of the lens 100. It is understood that, in other embodiments, the extending direction of the light exit groove 112 is not limited to the circular arc direction, but may be a non-circular arc direction. In one embodiment, the light exit groove 112 may extend in an irregular closed curve direction.

As shown in fig. 2, in order to increase the irradiation angle range of the lamp 10, in one embodiment, the second light emitting surface 114 is an arc-shaped curved surface structure, so that the second light emitting surface 114 has a better light emitting effect, and meanwhile, the light rays refract different angles of light rays at different positions of the same normal cross-sectional position through the second light emitting surface 114 of the lens unit 110, thereby increasing the irradiation angle range of the lamp 10.

As shown in fig. 3, in one embodiment, the light exit angle of the normal section of one end of the lens unit 110 is greater than the light exit angle of the normal section of the other end of the lens unit 110. Referring to fig. 4 to 6 together, the light exit angle of the lens unit 110 decreases from the end of the maximum light exit angle to the end of the minimum light exit angle, such that the corresponding light exit angle decreases or increases during the adjustment of the lens unit 110 in the position adjustment direction.

In one embodiment, the lamp further comprises an illumination collecting probe and a light intensity collecting probe, the illumination collecting probe and the light intensity collecting probe are both connected with the control end of the driving mechanism, the illumination collecting probe is used for collecting ambient illumination, and the light intensity collecting probe is used for collecting ambient light intensity, so that the illumination collecting probe and the light intensity collecting probe are better arranged. In one embodiment, the illumination acquisition probe and the light intensity acquisition probe are both arranged on the fixing frame, so that the illumination acquisition probe can better acquire illumination data of the surrounding environment of the lamp, and the light intensity acquisition probe can better acquire light intensity data of the surrounding environment of the lamp.

In one embodiment, the number of the lens units is multiple, the multiple lens units are sequentially connected, and at least one lens unit is connected with the fixing frame, so that the light-emitting angles of the multiple lens units can be synchronously adjusted. In the present embodiment, the plurality of lens units 110 are connected together, so that the light-emitting angles of the plurality of lens units 110 can be adjusted synchronously. Specifically, a plurality of lens units 110 are connected together to form a closed structure.

In one embodiment, the lens units 110 are sequentially connected to form a ring structure, so that the lens 100 can be adjusted along the position adjustment direction in a rotating manner, and the convenience of the position adjustment of the lens 100 is improved. In other embodiments, the sequential connection of the lens units 110 is not limited to forming a ring structure, but may form a rectangular structure or other polygonal structures. Of course, in other embodiments, the lens units 110 may be connected in sequence without forming a closed structure. In another embodiment, a plurality of lens units 110 are connected in series to form an arc-shaped structure. In one embodiment, each lens unit 110 is disposed corresponding to the light source 200, so that the light emitted from the light source 200 can be refracted out through the lens unit 110.

In one embodiment, the light-emitting angle range of each lens unit 110 is 120 ° to 135 °, so that the light-emitting angle range of the lens unit 110 is large. As shown in fig. 4, in an embodiment, the maximum light-emitting angle of the lens unit 110 is 135 °. When the maximum light-emitting angle position of the lens unit 110 is adjusted in the position adjustment direction to correspond to the light-emitting direction of the light source 200, the light-emitting angle of the lens unit 110 is maximum. In this embodiment, when the light-emitting angle of one of the lens units 110 is adjusted to be maximum, the light-emitting angles of the other lens units 110 are simultaneously adjusted to be maximum, at this time, the light-emitting angle of the whole lens 100 structure is maximum, the light spot pattern of the lens unit 110 at this time is as shown in fig. 7, and the light distribution curve diagram of the corresponding lens unit 110 is as shown in fig. 8.

In one embodiment, the minimum light-emitting angle of each lens unit 110 is 120 °. As shown in fig. 6, when the minimum light exit angle position of the lens unit 110 is adjusted in the position adjustment direction to correspond to the light exit direction of the light source 200, the light exit angle of the lens unit 110 is minimum. In this embodiment, when the light-exiting angle of one of the lens units 110 is adjusted to be minimum, the light-exiting angles of the other lens units 110 are simultaneously adjusted to be minimum, at this time, the light-exiting angle of the whole lens 100 structure is minimum, the light spot pattern of the lens unit 110 at this time is as shown in fig. 9, and the light distribution curve diagram of the corresponding lens unit 110 is as shown in fig. 10. In an embodiment, the normal cross-section corresponding to the minimum light-emitting angle position of the lens unit 110 is two concentric semicircular structures, that is, the first arc-shaped line and the second arc-shaped line of the normal cross-section corresponding to the minimum light-emitting angle position of the lens unit 110 are both semicircular arc-shaped lines. It is understood that in other embodiments, the normal cross-section corresponding to the minimum light-exiting angle position of the lens unit 110 is not limited to two concentric semicircular structures.

As shown in fig. 5, in an embodiment, there is an intermediate light exit angle between the minimum light exit angle and the maximum light exit angle of the lens unit 110. When the light exit angle is adjusted to an intermediate light exit angle between the maximum light exit angle position and the minimum light exit angle position of the lens unit 110 in the position adjustment direction of the lens unit 110, the light exit angle of the lens unit 110 is 127.5 °, and the light exit angle of the lens unit 110 at this time is the intermediate light exit angle. In this embodiment, when the light-emitting angle of one of the lens units 110 is adjusted to 127.5 °, and the light-emitting angles of the other lens units 110 are simultaneously adjusted to 127.5 °, the light-emitting angle of the entire lens 100 structure is 127.5 °, the light spot pattern of the lens unit 110 at this time is as shown in fig. 11, and the light distribution curve of the corresponding lens unit 110 is as shown in fig. 12.

It is understood that in other embodiments, the light-emitting angle range of the lens unit 110 is not limited to 120 ° to 135 °. That is, the maximum light-exiting angle of the lens unit 110 is not limited to 135 °, and similarly, the minimum light-exiting angle of the lens unit 110 is not limited to 120 °, and both the maximum light-exiting angle and the minimum light-exiting angle of the lens unit 110 can be changed by adjusting the structures of the respective positions of the lens unit 110.

As shown in fig. 1 and 13, in one embodiment, two adjacent lens units 110 are symmetrically disposed about a normal cross section, and two adjacent lens units 110 are symmetrically connected to form a lens unit group 110a disposed opposite to one light source 200, so that the lens 100 can be adjusted along both the front and back directions of the position adjustment direction of the lens units 110, and the light emitting angle of the light source 200 can be increased or decreased.

In the present embodiment, the ends of the normal cross sections of two adjacent lens units 110 with larger light-emitting angles are connected together, or the ends of the normal cross sections of two adjacent lens units 110 with smaller light-emitting angles are connected together, so that two adjacent lens units 110 are symmetrically arranged about the normal cross section. Because the areas of the normal cross sections at the two ends of each lens unit 110 are not equal, and the two adjacent lens units 110 are symmetrically arranged about the normal cross sections, the ends with the equal areas of the normal cross sections of the two adjacent lens units 110 can be connected together, so that the connection positions of the two adjacent lens units 110 are smooth, and the structure of the whole lens 100 is smooth and coherent. In the present embodiment, a plurality of lens units 110 are arrayed end to end along a closed circular track to form a ring-shaped full-page lens 100 structure.

In this embodiment, the plurality of lens units are all glued to the fixing ring, so that the plurality of lens units are all connected to the fixing ring. In one embodiment, the retaining ring is a circular ring structure.

In one embodiment, the bracket 120a includes a fixed shaft 122 and a plurality of coupling plates 124, each of which has one end coupled to the fixed shaft 122 and the other end coupled to the fixing ring. In the present embodiment, the number of the connection plates 124 is three. In one embodiment, the plurality of connection plates 124 are spaced along the circumference of the fixing shaft 122 to better connect the fixing frame 120 to the lens unit 110. In other embodiments, the number of connecting plates is not limited to three, but may be four or another number.

As shown in fig. 1, in one embodiment, the light exit groove 112 is disposed toward the light source 200, and the relative position of the lens unit 110 and the light source 200 is adjustable. In one embodiment, the number of light sources 200 is N. The number of the lens units 110 is 2N, and two adjacent lens units 110 are symmetrically disposed with respect to the normal cross section, i.e., two adjacent lens units 110 constitute a lens unit group 110a, thus constituting N lens unit groups 110 a. The N lens unit groups 110a correspond to the N light sources 200 one to one, that is, each light source 200 is disposed corresponding to the corresponding lens unit group 110a, so that the light emitted from each light source 200 can be refracted to the outside through the lens unit group 110 a.

The driving shaft 600 is respectively located in the first through hole 310 and the second through hole 410, and the driving shaft 600 is respectively rotatably connected with the circuit board 300 and the heat sink 500, so that the fixing frame 120 rotates along with the driving shaft 600 relative to the circuit board 300, because the fixing frame 120 is connected with at least one lens unit 110, and the lens units 110 are connected into a whole, the N lens unit groups 110a all rotate along with the fixing frame 120, so that the N lens unit groups 110a all move relative to the corresponding light source 200, and each lens unit group 110a is adjusted to different positions relative to the light source 200 along the position adjusting direction, thereby realizing adjustment of different light emitting angles of the lamp 10.

It is understood that the driving shaft 600 can be manually adjusted to adjust different light emitting angles of the lamp 10 along the position adjusting direction. In other embodiments, the driving shaft 600 can also adjust different light-emitting angles of the lamp 10 in the position adjusting direction in a power-driven manner.

Referring again to fig. 1, in one embodiment, the driving mechanism 430 includes a motor 433 and a connecting shaft 435, one end of which is connected to a power output end of the motor and the other end of which is connected to the driving shaft 600. When the motor drives the connecting shaft to rotate, the connecting shaft drives the driving shaft 600 and the fixing frame 120 to rotate, so that the light transmitting units rotate relative to the circuit board 300 along with the fixing frame 120, and each light transmitting unit group moves relative to the corresponding light source 200, thereby realizing the adjustment of the light emitting angle of the lamp 10. In other embodiments, the motor may be replaced by a rotary cylinder.

As shown in fig. 2, in one embodiment, the luminaire further comprises a remote control center, and the control unit is connected with the remote control center. In this embodiment, the control unit is connected to the control end of the driving mechanism 430. Specifically, in this embodiment, the control unit is connected to the remote control center by wire or wirelessly. It will be appreciated that the remote control center may be a remote central control center or a field remote control unit to control the adjustment of the light exit angles of a single or multiple luminaires within an area.

In one embodiment, the working process of the lamp is as follows: the remote control center sends any angle signal within the adjustable angle range to the acquisition module, and the control unit judges whether the angle is in the storage module 440. If the storage module 440 has the angle data, the driving mechanism 430 drives the rotation shaft to drive the full-page lens 100 to rotate to the target angle position, and all the LEDs are turned on, so as to obtain the required light-emitting angle of the lamp. If the storage module 440 does not have the angle data, the detection module 410 detects the current angle position of the lens 100, obtains the target angle position of the full-page lens 100 through multiple feedback optimization between the detection module 410 and the driving mechanism 430, lights all the LEDs, can obtain the required light-emitting angle of the lamp, and simultaneously stores the target angle position information and the corresponding driving information at the moment, so as to facilitate condition calling during the next adjustment.

When the light-emitting angle of the lamp is not specifically required, a stepless adjusting signal can be sent through a touch screen or an entity key of the remote control center, and the light-emitting angle of the lamp can be adjusted from large to small or from small to large until the effect of the lamp on the use site is satisfied. When a lamp system consisting of a series of N lamps needs to be adjusted in a unified manner, namely when the N-level lamp system needs to be adjusted in a unified manner, the remote control center sends control signals to all the lamps in a unified manner, and N-level adjustment and control can be achieved.
