Description

Technical Field

[0001] This utility model relates to the field of lighting fixtures, and in particular to an adjustable focus downlight. Background Technology

[0002] Modern housing designs often feature varying ceiling heights, and during actual renovations, different design schemes and ceiling heights frequently result in different actual ceiling heights. This makes it difficult to purchase suitable lighting fixtures. To address this issue, some downlights offer adjustable focus to meet user needs. After purchasing the downlights, users can adjust the focus during installation to achieve the desired effect.

[0003] However, in existing designs, downlights installed in ceilings or similar structures cannot be directly adjusted in real time. The downlights need to be removed, and the relative positions of the light panel and lens need to be adjusted before they can be reinstalled and the effect tested. This kind of adjustment is relatively cumbersome and not intuitive. If they could be adjusted directly without disassembly, it would reduce the cumbersomeness of adjustment and facilitate subsequent use and maintenance. Utility Model Content

[0026] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0027] Reference Figures 1 to 6 An embodiment of the adjustable focus downlight of this utility model is presented:

[0028] An adjustable focus downlight includes a lamp body 1, a reflector 2, an outer ring 3, a light-emitting panel, and a lens.

[0029] The light-emitting panel is fixedly connected to the bottom inner side of the lamp body 1 by screws. A heat dissipation grille 13 is provided at the bottom of the lamp body 1, allowing the light-emitting panel to dissipate heat. Through-holes 14 are provided between the heat dissipation grilles 13, through which external wiring passes and connects to the light-emitting panel. Three first connection holes 11 are provided on the top outer side of the lamp body 1. The lamp body connecting slider 15 is a connecting stud, which is threaded into the first connection holes 11. Second connection holes 12 are also provided between the first connection holes 11, and lamp body positioning blocks are fixed to the second connection holes 12 by screws.

[0030] The reflector cup 2 has three inclined reflector cup grooves 21 that are adapted to the lamp body connecting slider 15. The reflector cup 2 is secured to the side of the lamp body 1 by the cooperation of the lamp body connecting slider 21 and the reflector cup grooves 21, and the relative position of the lamp body connecting slider 15 within the reflector cup grooves 21 can be adjusted. In actual use, the reflector cup 2 is first placed on the corresponding position on the outside of the lamp body 1, and then the connecting stud is connected to the lamp body 1, thus securing the reflector cup 2 and the lamp body 1. A limiting groove 22 is provided on the bottom inner side of the reflector cup 2, and three connecting buckles 23 are provided at the bottom of the limiting groove 22. The lens is secured within the limiting groove 22 by the connecting buckles 23. Three reflector cup connecting springs 24 are provided on the side of the reflector cup 2. Reflector cup connecting teeth 25 are provided on the inner side of the reflector cup 2. The rotation angle of the reflector cup 2 can be positioned by the cooperation of the lamp body positioning block and the reflector cup connecting teeth 25.

[0031] The inner side of the outer ring 3 is provided with a vertically arranged outer ring connecting groove 31 adapted to the lamp body connecting slider 15. The lamp body connecting slider 15 is limited and positioned within the outer ring connecting groove 31. The inner side of the outer ring 3 is also provided with a horizontally arranged annular outer ring limiting groove 323. Through the cooperation of the outer ring limiting groove 323 and the reflector cup connecting spring 24, the reflector cup 2 and the outer ring 3 are connected by a snap-fit ​​method. The outer side of the outer ring 3 can also be connected to a cantilever hook or other fixed structure, thereby fixing it to an external environment such as a ceiling or suspended ceiling.

[0032] When the reflector cup 2 is rotated, the reflector cup groove 21 presses the lamp body connecting slider 15. At this time, because the outer ring connecting groove 21 limits the horizontal movement of the lamp body connecting slider 15, the lamp body connecting slider 15 can only move in the vertical direction, realizing rising and falling, thereby adjusting the relative position of the lamp body 1 and the reflector cup 2, thereby adjusting the relative position of the light-emitting plate and the lens, thereby adjusting the focal length.

[0033] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the contents of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
