The normal section of the first light emitting surface is a first arc line 112a, the light emitting groove 112 faces the light source 200, and the relative position between the lens unit 110 and the light source 200 is adjustable, so that the light source 200 can be adjusted to different relative positions with respect to the lens unit 110.
As shown in fig. 4 and 5, 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. 4 and fig. 5, in an embodiment, a surface of each lens unit 110 facing away from the surface having the light exit groove 112 is a second light exit surface 114. The second light emitting surface 114 corresponds to the first light emitting surface, so that the light emitted from the light source 200 sequentially passes through the first light emitting surface and the second light emitting surface 114 to be refracted out. In one embodiment, a normal cross section of the second light emitting surface 114 is a second arc line 114 a. The relative positions of the first arc line 112a and the second arc line 114a are different at different normal cross-sectional positions of the lens unit 110 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. 4, 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. 5, 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. 6 to 8 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 light-emitting angle range of the 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. 6, 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. 9, and the light distribution curve diagram of the corresponding lens unit 110 is as shown in fig. 10.
In one embodiment, the minimum light-emitting angle of the lens unit 110 is 120 °. As shown in fig. 8, 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. 11, and the light distribution curve diagram of the corresponding lens unit 110 is as shown in fig. 12. 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. 7, 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. 13, and the light distribution curve of the corresponding lens unit 110 is as shown in fig. 14.
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. 3 and fig. 15, 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.
As shown in FIG. 3, in one embodiment, the lens 100 further includes a holder 120, and at least one lens unit 110 is coupled to the holder 120 such that the plurality of lens units 110 move with the holder 120 when adjusted in the position adjustment direction. In one embodiment, the fixing frame 120 includes a fixing shaft 122 and a plurality of connecting plates 124, each having one end connected to the fixing shaft 122 and the other end connected to the lens unit 110. 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. 3, 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.
As shown in fig. 3, in one embodiment, the lamp 10 further includes a circuit board 300, and the light source 200 is disposed on and electrically connected to the circuit board, so that the light source 200 is electrically connected to the circuit board. In one embodiment, the N light sources 200 are disposed on the circuit board 300 at intervals along the circumference of the circuit board 300, so that the lamp 10 has a better lighting effect. In this embodiment, the circuit board 300 is a PCB, so that the thickness of the circuit board 300 is small. In one embodiment, the N light sources 200 are all disposed on the same surface of the circuit board, so that the N light sources 200 all emit light in the same direction. In one embodiment, the lamp 10 further includes a heat sink 500, and the circuit board 300 is disposed on the heat sink 500, so that the heat sink 500 dissipates heat of the circuit board 300, and the heat dissipation performance of the lamp 10 is improved. In this embodiment, the circuit board is attached to the heat sink, so that the heat on the circuit board can be transferred to the heat sink for heat dissipation. In this embodiment, each light source 200 is disposed on a side of the circuit board away from the heat sink. In one embodiment, the lamp further comprises a heat-conducting adhesive layer, and the circuit board is adhered to the radiator through the heat-conducting adhesive layer, so that heat on the circuit board is quickly transferred to the radiator.
As shown in fig. 3, in one embodiment, the luminaire 10 further includes a rotating shaft 600, and the rotating shaft 600 is connected to the fixing frame 120. The circuit board 300 is formed with a first through hole 310, and the heat sink 500 is formed with a second through hole 410 communicating with the first through hole 310. The rotating shaft 600 is respectively located in the first through hole 310 and the second through hole 410, and the rotating 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 rotating 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 can be understood that the rotating 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 rotating shaft 600 can also be driven by power to adjust different light-emitting angles of the lamp 10 along the position adjusting direction.
In one embodiment, the luminaire 10 further comprises the adjustment system 400 of any of the embodiments described above. The acquisition module acquires target position information between the lens and the light source. The detection module 410 detects relative position information of the lens 100 and the light source 200. The comparison module compares the current position information with the target position information of the lens 100 and outputs a control signal according to the adjustment value of the lens 100. The driving module 430 drives the lens 100 to move relative to the light source 200 according to the control signal.
The lamp and the adjusting system 400, the lamp includes the light source 200, the lens 100 and the adjusting system 400, since the relative position of the light source 200 and the lens unit 110 is adjustable, the driving module 430 of the adjusting system 400 drives the lens 100 to move relative to the light source 200, and since the adjusting system 400 adjusts by using the adjusting method, it can adapt to the adjustment of any target position within the adjusting position range of the lamp, and realize the stepless adjustment of the light distribution of the lamp.
Referring to fig. 3 again, in one embodiment, the power output end of the driving module 430 is connected to the rotating shaft 600, so that the driving module 430 drives the rotating shaft 600 to rotate relative to the heat sink 500 and the circuit board 300, respectively, to achieve automatic adjustment of different light-emitting angles of the lamp 10. In this embodiment, the driving module 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 rotating shaft 600. When the motor drives the connecting shaft to rotate, the connecting shaft drives the rotating 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 adjusting 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 includes a remote control center 460, and the obtaining module is further connected to the remote control center 460. In this embodiment, the obtaining module is connected to the control end of the driving module 430. The acquisition module is also connected to the remote control center 460, such that the acquisition module is communicatively connected to the remote control center 460. Specifically, in this embodiment, the acquisition module is connected to the remote control center 460 through a wired or wireless connection. It is understood that the remote control center 460 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 460 sends any angle signal within the adjustable angle range to the obtaining module, and the control unit determines whether the angle is in the storage module 440. If the storage module 440 stores the angle data, the driving module 430 drives the rotation shaft to drive the full-page lens 100 to rotate to the target angle position, and lights all the LEDs, 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 entire lens 100 through multiple feedback optimization between the detection module 410 and the driving module 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 next adjustment.
When there is no specific requirement for the light-emitting angle of the lamp, a stepless adjusting signal can be sent through the touch screen or the physical key of the remote control center 460, 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 satisfactory. 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 460 sends control signals to all the lamps in a unified manner, so that N-level adjustment and control can be realized. Fig. 16 is a schematic view of a topology of a lamp system.
