Description

Technical Field

[0001] The utility model relates to the technical field of lighting fixtures, and particularly relates to a lighting fixture. Background Art

[0002] At present, people's demands for lighting of lighting fixtures are becoming more and more diverse, such as the color temperature and the light-emitting angle of the lighting fixtures. In order to meet the different color temperature requirements of users, lamp beads with different color temperatures are usually configured for the lighting fixtures, and the color temperature of the lighting fixtures is adjusted by controlling whether the lamp beads with different color temperatures work or not. However, since the light-emitting angle of the lighting fixture is determined by the lens, in order to meet the different irradiation range requirements of users, different lenses need to be configured for the lighting fixture. For example, by configuring a 15-degree lens, a 15-degree light-emitting angle can be correspondingly achieved. Therefore, users need to select lighting fixtures configured with different lenses according to their own needs. However, when users need to change the irradiation range of the lighting fixture, they usually need to additionally purchase a whole lamp configured with a corresponding lens to achieve the required light-emitting angle, which is rather troublesome to operate and has a high cost. And in order to meet the different needs of customers, manufacturers need to produce multiple types of lenses, and for this purpose, they also need to develop molds for multiple types of lenses, which greatly increases the production cost of the manufacturers. Summary of the Utility Model

[0035] Referring to Figures 1 to 6 , an embodiment of the present utility model provides a lighting fixture, which includes a housing 100, a light emitting device 200, a lens device 300, a control device, and a driving device. The housing 100 has an installation cavity 110, and a light outlet 120 communicating with the installation cavity 110 is formed on the side wall of the housing 100. The light emitting device 200 is installed in the installation cavity 110. One side of the light emitting device 200 close to the light outlet 120 has a first light source 231 and a second light source 232, and the first light source 231 and the second light source 232 have different color temperatures. The control device is electrically connected to the first light source 231 and the second light source 232, and the control device can control the first light source 231 and / or the second light source 232 to be turned on or off. The lens device 300 is fixedly installed at the light outlet 120, and the lens device 300 can block all of the first light source 231 and the second light source 232. Among them, a driving device is provided between the light emitting device 200 and the housing 100, and the driving device can drive the light emitting device 200 to move relative to the housing 100 closer to or farther away from the lens device 300.

[0036] By adopting the lamp of the embodiment of the utility model, the light emitting device 200 has a first light source 231 and a second light source 232, and the first light source 231 and the second light source 232 have different color temperatures, so that the user can control the first light source 231 to emit light or the second light source 232 to emit light, or the first light source 231 and the second light source 232 to emit light at the same time through the control device, so as to meet the different color temperature requirements of customers. In addition, by movably installing the light emitting device 200 in the installation cavity 110, a driving device is arranged between the light emitting device 200 and the housing 100, so that the user can drive the light source device to move closer to or away from the lens device 300 through the driving device, so as to adjust the distance between the light source device and the lens device 300, and then adjust the light emitting angle of the lamp. Specifically, as the distance between the light source device and the lens device 300 gradually decreases, the light emitting angle of the light source device at the light emitting port will gradually increase, and when the distance between the light source device and the lens device 300 gradually increases, the light emitting angle of the light source device at the light emitting port will gradually decrease, so as to meet the different light emitting angle requirements of users. It can be seen that the lamp in the embodiment of the utility model can conveniently adjust the color temperature and the light-emitting angle, which is helpful to meet the different lighting needs of users.

[0037] In addition, by adopting the above-mentioned structure, users can easily adjust the light-emitting angle of the lamp through the driving device, without having to replace lamps with different lenses 320 as in the prior art, which greatly saves users the cost of purchasing lamps. In addition, manufacturers do not need to develop multiple molds for different lenses 320 to adapt to lamps with different light-emitting angles, thereby greatly saving manufacturers' lamp production costs.

[0038] It can be understood that the lamp in the embodiment of the present invention may be a floodlight, or may be a spotlight or other types of lamps, and the present invention does not make any specific limitation on this.

[0039] Reference Figures 1 to 3 In some embodiments, the driving device is located on the side of the light-emitting device 200 away from the light outlet 120, and the driving device includes a first driving member and a second driving member that are threaded together. The first driving member is a nut 410 and is disposed on the housing 100, and the second driving member is a screw 400 and can abut against the light-emitting device 200. The first driving member and the second driving member can rotate relative to each other, and the second driving member can push the light-emitting device 200 to move relative to the housing 100 and close to the lens device 300.

[0040] By adopting the above structure, when the screw 400 rotates relative to the nut 410, the screw 400 can move relative to the nut 410 and abut against the light-emitting device 200, and push the light-emitting device 200 to move closer to the lens 320 assembly, so that the distance between the light-emitting device 200 and the lens device 300 can be adjusted, thereby facilitating the user to easily adjust the light-emitting angle of the lamp.

[0041] It can be understood that, in order for the screw 400 to push the light-emitting device 200 to move, in addition to abutting the screw 400 against the light-emitting device 200, the screw 400 can also be directly connected to the light-emitting device 200, and the present utility model does not make specific limitations on this.

[0042] Refer to Figures 1 to 3 , in some embodiments, the first driving member is the nut 410, the second driving member is the screw 400 threadedly connected to the nut 410, the nut 410 is fixedly arranged on the housing 100, and the screw 400 can rotate relative to the nut 410 and move relative to the housing 100 closer to or away from the light-emitting device 200.

[0043] By adopting the above structure, when it is necessary to adjust the light-emitting angle of the lamp, only by rotating the screw 400 can the screw 400 be driven to move to adjust the distance between the light-emitting device 200 and the lens device 300, with a simple structure and convenient operation, which is beneficial for the user to adjust the light-emitting angle of the lamp.

[0044] It can be understood that, refer to Figures 1 to 3 , in some embodiments, the nut 410 and the housing 100 are of an integrally formed structure, which can make the production and processing of the lamp more convenient, and at the same time can reduce the number of components of the lamp, facilitating the assembly and fitting of the lamp. Of course, for the nut 410 fixedly arranged on the housing 100, in addition to setting the nut 410 and the housing 100 as an integrally formed structure, the nut 410 can also be fixedly installed on the housing 100 through fastening structures such as screws and buckles, and the present utility model does not make specific limitations on this.

[0045] It can be understood that, in addition to fixedly arranging the nut 410 on the housing 100, in some embodiments, the nut 410 can also be rotatably installed on the housing 100. When it is necessary to adjust the light-emitting angle of the lamp, only by rotating the nut 410 can the screw 400 be driven to move to adjust the distance between the light-emitting device 200 and the lens device 300. The present utility model does not make specific limitations on the specific connection relationship between the nut 410 and the housing 100.

[0046] It can be understood that the above first driving member is the nut 410 and the second driving member is the screw 400, which is only for Figures 1 to 3An exemplary illustration. In some embodiments, the first driving member may also be set as a screw 400 and disposed in the housing 100, and the second driving member may be set as a nut 410 and capable of being connected to or abutting against the light-emitting device 200. Thus, when the nut 410 rotates relative to the screw 400, the nut 410 can move relative to the screw 400 and push the light-emitting device 200 to move closer to the lens 320 assembly, so as to adjust the distance between the light-emitting device 200 and the lens device 300, and further facilitate the user to easily adjust the light-emitting angle of the lamp.

[0047] Referring to Figures 1 to 3 , in some embodiments, the nut 410 is disposed in the housing 100 and extends into the installation cavity 110. The screw 400 is threadedly connected to the nut 410 and located in the installation cavity 110. The housing 100 is provided with an adjustment hole communicating with the threaded hole 411 of the nut 410. One end of the screw 400 facing the adjustment hole is provided with an adjustment portion 401, and a plugging member 420 is detachably installed in the adjustment hole.

[0048] By adopting the above structure, when it is necessary to adjust the light-emitting angle of the lamp, the plugging member 420 can be removed from the adjustment hole, and an adjustment tool adapted to the screw 400 is inserted into the adjustment hole and abuts against the adjustment portion 401 of the screw 400, so as to be able to rotate the screw 400 to adjust the distance between the light-emitting device 200 and the lens device 300. When the light-emitting angle adjustment is completed or there is no need to adjust the light-emitting angle, the plugging member 420 can be installed in the adjustment hole to plug the threaded hole 411 of the nut 410. Thus, not only can the screw 400 be protected, but also the cleanliness of the threaded hole 411 can be ensured. In addition, it can also avoid the situation that the screw 400 is accidentally screwed due to the screw 400 being exposed outside, which is beneficial to fixing the light-emitting angle of the lamp.

[0049] It can be understood that the above adjustment tool adapted to the screw 400 can specifically be a screwdriver.

[0050] Referring to Figures 1 to 6 , in some embodiments, the opposite sides of the light-emitting device 200 have abutting portions 240. The abutting portions 240 are provided with sliding grooves 241. The housing 100 is provided with a locking structure. The locking structure includes locking members 130 corresponding to the abutting portions 240. The locking members 130 are movably installed in the housing 100 and movably inserted into the corresponding sliding grooves 241. The locking members 130 can move relative to the housing 100 closer to or away from the installation cavity 110. When all the locking members 130 abut against the inner walls of the corresponding sliding grooves 241, the locking structure can lock the light-emitting device 200.

[0051] By adopting the above structure, when it is necessary to adjust the light-emitting angle of the lamp, the locking member 130 can be loosened so that the light-emitting device 200 can move relative to the locking member 130 closer to or farther away from the lens device 300. After the light-emitting angle is adjusted, the locking member 130 can be moved to abut against the inner wall of the corresponding sliding groove 241, and the two opposite locking members 130 can cooperate to lock the light-emitting device 200, thereby fixing the light-emitting device 200 at the set position. Thus, through the mutual cooperation of the locking member 130 and the sliding groove 241, not only can the movement stability of the light-emitting device 200 be improved, but also the light-emitting device 200 can be locked by the locking member 130, so that the light-emitting device 200 is fixed at the set position after the light-emitting angle is adjusted.

[0052] It can be understood that, in order to improve the movement stability of the light-emitting device 200, a guiding post can also be arranged in the installation cavity 110, and the light-emitting device 200 is movably sleeved on the guiding post.

[0053] Refer to Figures 1 to 6 , in some embodiments, the light-emitting device 200 includes a lamp board 210, the lamp board 210 is movably installed in the installation cavity 110, the first light source 231 and the second light source 232 are installed on the side of the lamp board 210 close to the lens device 300, the number of both the first light source 231 and the second light source 232 is at least two, the control device is electrically connected to all the first light sources 231 and all the second light sources 232, and the control device can control the first light source 231 and / or the second light source 232 to be turned on or off.

[0054] By adopting the above structure, by setting the number of both the first light source 231 and the second light source 232 to be at least two, the light-emitting brightness of the lamp can be increased, and the adjustment of the color temperature of the lamp can be made more flexible.

[0055] Refer to Figures 1 to 6 , in some embodiments, the control device includes a constant current power supply 140, a first switch and a second switch. All the first light sources 231 are connected in series with each other to form a first series circuit, all the second light sources 232 are connected in series with each other to form a second series circuit, the first series circuit and the second series circuit are connected in parallel with each other, the first switch is arranged between the constant current power supply 140 and the first series circuit, and the second switch is arranged between the constant current power supply 140 and the second series circuit.

[0056] By adopting the above structure, the constant current power supply 140 can supply power to the first light source 231 and the second light source 232 simultaneously. All the first light sources 231 can be controlled to turn on or off through the first switch, and all the second light sources 232 can be controlled to turn on or off through the second switch. Thereby, the adjustment of the color temperature of the lamp is made more convenient. Moreover, compared with the existing method of using two power supplies to control the first light source 231 and the second light source 232 respectively, the lamp of the embodiment of the present utility model only uses one constant current drive power supply, which is beneficial to saving energy and reducing the number of components of the lamp.

[0057] It can be understood that the first light source 231 can specifically be a warm color light source, and the second light source 232 can specifically be a cold color light source. Thus, when the first switch is closed and the second switch is open, only the first light source 231 emits light, and at this time the lamp emits warm light; when the first switch is open and the second switch is closed, only the second light source 232 emits light, and at this time the lamp emits cold light; when both the first switch and the second switch are closed, both the first light source 231 and the second light source 232 emit light, and at this time the warm light emitted by the first light source 231 and the cold light emitted by the second light source 232 can be mixed with each other to form neutral light; when both the first switch and the second switch are open, the lamp is turned off. Thereby, the lamp can provide three color temperature options for users, which is beneficial to meeting the different color temperature requirements of users.

[0058] Refer to Figures 1 to 6 , in some embodiments, the light emitting device 200 further includes a heat dissipation plate 220, and the heat dissipation plate 220 is movably installed in the installation cavity 110 and is in mutual contact with the surface of the lamp board 210 facing away from the lens device 300.

[0059] By adopting the above structure, the setting of the heat dissipation plate 220 can not only provide support for the lamp board 210. In addition, the heat dissipation plate 220 is in mutual contact with the surface of the lamp board 210 facing away from the lens device 300. Thus, the heat generated by the lamp board 210 can be quickly transferred to the heat dissipation plate 220, so that the heat dissipation of the lamp board 210 can be facilitated, which is beneficial to extending the service life of the lamp board 210.

[0060] Refer to Figures 1 to 6 , in some embodiments, a plurality of grid plates 221 are provided on the side of the heat dissipation plate 220 facing away from the lamp board 210. The grid plates 221 extend towards the side facing away from the lamp board 210 relative to the heat dissipation plate 220, and adjacent two grid plates 221 are arranged at intervals.

[0061] By adopting the above structure, the setting of the grid plates 221 can further accelerate the dissipation of heat. Thus, the heat dissipation effect of the heat dissipation plate 220 can be further improved, enabling the lamp board 210 to dissipate heat quickly, which is beneficial to extending the service life of the lamp board 210.

[0062] It can be understood that, in some embodiments, the opposite sides of the light-emitting device 200 are provided with abutting portions 240. The abutting portions 240 are provided with sliding grooves 241. The housing 100 is provided with a locking structure. The locking structure includes locking members 130 corresponding to the abutting portions 240. The locking members 130 are movably installed in the housing 100 and movably inserted into the corresponding sliding grooves 241. The locking members 130 can move relative to the housing 100 closer to or away from the installation cavity 110. When all the locking members 130 abut against the inner walls of the corresponding sliding grooves 241, the locking structure can lock the light-emitting device 200. Among them, the abutting portions 240 can be specifically arranged on the heat dissipation plate 220.

[0063] Referring Figures 4 to 6 , each first light source 231 corresponds to each second light source 232 one by one and forms a group of dual-color light groups 230. In each group of dual-color light groups 230, the first light source 231 and the second light source 232 are arranged side by side; the lens device 300 includes a mounting plate 310 and lenses 320 corresponding to each group of light groups one by one. The lenses 320 are arranged on the mounting plate 310 and are located above the corresponding dual-color light groups 230. The lenses 320 can block the first light source 231 and the second light source 232 of the corresponding dual-color light groups 230.

[0064] By adopting the above structure, each first light source 231 and each second light source 232 are corresponded one by one to form a group of dual-color light groups 230, and the first light source 231 and the second light source 232 of each group of dual-color light groups 230 are arranged side by side, which is beneficial to make the light of two color temperatures mix more evenly when the first light source 231 and the second light source 232 are lit simultaneously. In addition, by arranging lenses 320 corresponding to each group of dual-color light groups 230 on the mounting plate 310, and the lenses 320 can block the first light source 231 and the second light source 232 of the corresponding dual-color light groups 230, thus the refraction of the lenses 320 can make the two light sources in each group of dual-color light groups 230 mix more evenly when lit simultaneously, reducing the risk of poor color mixing in some areas.

[0065] It can be understood that, in order to improve the uniformity of the mixing of the two light sources in each group of dual-color light groups 230 when lit simultaneously, the first light source 231 and the second light source 232 can be arranged side by side and adhered to each other, so that the distance between them is as small as possible.

[0066] It can be understood that, referring Figures 1 to 6 , in some embodiments, the lens 320 is specifically a hemispherical lens.

[0067] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made without departing from the spirit of the present invention within the knowledge scope of those of ordinary skill in the art.
