Description

Technical Field

[0001] The utility model relates to the technical field of lighting lamps, in particular to a limiting structure of an angle-adjustable lamp and the lamp. Background Art

[0002] Angle-adjustable lamps refer to lamps that are designed with adjustable illumination angles. Such lamps usually have flexible lamp heads or lamp arms. Users can adjust the angle of light illumination as needed to adapt to different lighting needs and provide more flexible and personalized lighting effects, such as the invention patent application with application number CN202010486414.5. In particular, for lamps that need to adjust the illumination direction to a vertical direction, screws or rivets are generally used for fastening and limiting, and the requirements for adjusting the tightness are high. For example, the utility model patent application with application number CN202320618723.2 uses an adjustment ring and a rotating ring to achieve vertical adjustment of the light source module. Not only does it require an overall modification of the lamp, it is also unable to adapt to various existing angle-adjustable lamps and has poor universality. It is also necessary to control the matching degree between the arc rack and the first limit slider, as well as the processing accuracy of the arc rack. The processing accuracy requirements are high, otherwise the vertical illumination angle positioning of the lamp will be inaccurate. Utility Model Content

[0035] In order to better understand the position limiting structure of the angle-adjustable lamp of the present application, the position limiting structure of the angle-adjustable lamp of the present application is further explained below:

[0036] Please also refer to Figures 1 to 3In one embodiment, a limiting structure 10 for an angle-adjustable lamp includes a limiting assembly 200 and a lamp housing 100 for rotationally connecting to a light source module. When the light emission direction of the light source module is the same as the direction of gravity, a limiting stop gap 101 is formed between the circumference of the light source module and the inner wall of the lamp housing 100.

[0037] The above-mentioned limiting structure 10 of the angle-adjustable lamp utilizes the lamp housing 100, which is the original lamp housing 100 for being rotatably connected to the light source module, so that the first limiting member 210 and the second limiting member 220 are both detachably connected to the lamp housing 100, and the first limiting member 210 and the second limiting member 220 are both located at the limiting stop gap 101, and the first limiting member 210 and the second limiting member 220 are relatively arranged on both sides of the light source module, and at least part of the peripheral wall of the light source module and at least part of the inner wall of the lamp housing 100 are respectively relatively abutted against the two side walls of the first limiting member 210 and the two side walls of the second limiting member 220, that is, when the irradiation direction of the light source module is the direction of gravity, the first limiting member 210 and the second limiting member 220 are clamped to the lamp housing 100, so that the lamp housing 100 is against the first limiting member 210 and the second limiting member 220 0 plays a supporting role. At this time, the first limit member 210 and the second limit member 220 interfere with the two sides of the light source module to play a stopping role on the relative sides of the light source module, thereby realizing the vertical adjustment of the illumination angle of the light source module, and it is not easy to deviate, and the adjustment accuracy is high.

There is no need to adjust the lamp housing 100 and the light source module, and for lamp housings 100 and light source modules of different sizes, only the size of the first limit member 210 and the second limit member 220 needs to be adjusted.

In addition, the processing efficiency of the limiting assembly 200 is also improved.

[0040] Please also refer to Figures 1 to 3 In one embodiment, the first limiting member 210 is snapped onto the lamp housing 100 , which ensures the detachability of the first limiting member 210 on the lamp housing 100 and better ensures the connection stability between the first limiting member 210 and the lamp housing 100 .

[0041] Please also refer to Figures 1 to 3 In one embodiment, the second limiting member 220 is snapped onto the lamp housing 100 , which ensures the detachability of the second limiting member 220 on the lamp housing 100 and better ensures the connection stability between the second limiting member 220 and the lamp housing 100 .

Furthermore, the lamp housing 100 is provided with a snap-fitting groove 102, and the stopper ring 200A is snap-fitted into the snap-fitting groove 102, thereby ensuring a stable snap-fitting of the first stopper 210 and the second stopper 220 to the lamp housing 100.

[0043] Please also refer to Figures 1 to 3In one embodiment, a first grip portion 230 is connected to the first limiting member 210, the first grip portion 230 is located at the limiting stop gap 101, and the first grip portion 230 is respectively arranged to avoid the light source module and the lamp housing 100, and the first grip portion 230 is located on a side of the first limiting member 210 close to the light outlet of the light source module, which is conducive to applying force to the first limiting member 210 and the second limiting member 220, and further facilitates the removal of the first limiting member 210 and the second limiting member 220 from the lamp housing 100.

[0044] Please also refer to Figures 1 to 3 In one embodiment, the first handle 230 at least partially protrudes from the limit stop gap 101 , which further facilitates the user to remove the first limit member 210 from the lamp housing 100 through the first handle 230 .

Therefore, the second handle will not be described in detail.

[0047] This application also provides a lamp. Please refer to Figures 4 and 5 A lamp 10A in one embodiment includes a light source module 20 and a position limiting structure 10 of the angle-adjustable lamp according to any of the above embodiments. The light source module 20 is rotatably connected to the lamp housing 100. Figures 1 to 3 When the light emitting direction of the light source module 20 is aligned with the direction of gravity, a stop gap 101 is formed between the circumference of the light source module 20 and the inner wall of the lamp housing 100.

The first and second limiting members 210 and 220 have a supporting effect. At this time, the first limiting member 210 and the second limiting member 220 interfere with the two sides of the light source module 20 to act as a stop on the relative sides of the light source module 20, thereby realizing the vertical adjustment of the illumination angle of the light source module 20, and it is not easy to deviate, and the adjustment accuracy is high.
