Description

Technical Field

[0001] The utility model belongs to the technical field of downlights, and in particular relates to a free-opening frameless downlight. Background Art

[0002] Downlights are lighting fixtures that are commonly used in our daily lives. The installation method requires drilling a hole in the ceiling of the building, and then installing the downlight in the hole.

[0003] The existing downlights are generally embedded downlights, and the existing embedded downlights are generally installed in the opening position of the ceiling by means of torsion spring clips. During installation, the lamp housing together with the torsion spring clips are placed in the opening position on the ceiling surface, and finally the torsion spring clips are released. After the torsion spring clips are reset, they are clamped on the inner side of the ceiling, and the frame is clamped on the outer side of the ceiling, and the two fix the downlight on the ceiling. Although the downlight can be installed and fixed by means of the torsion spring clips, since the torsion spring clips are fixedly arranged at both ends of the downlight, the position of the torsion spring clips cannot be adjusted. When installing the downlight, if the aperture of the opening on the ceiling surface is smaller than or larger than the installation size of the torsion spring clip, resulting in a mismatch in installation, the downlight cannot be installed, and it is necessary to separately open an opening of a size suitable for the installation of the torsion spring clip on the surface of the downlight, which makes the installation more troublesome and cannot be adaptively adjusted. Utility Model Content

[0004] The purpose of the utility model is to provide a free-opening frameless downlight to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above purpose, the utility model provides the following technical solution: a free-opening frameless downlight, comprising:

[0006] A downlight, comprising a lampshade and an aluminum base plate, wherein the lampshade is arranged in an arc-shaped transparent shape and the aluminum base plate is arranged inside the lampshade, a plurality of lamp beads are evenly distributed on the surface of the aluminum base plate, a base plate is fixed to the top of the lampshade by screws, a quick-release assembly for installing the downlight is provided on the surface of the base plate, and the installation position of the installation block can be adjusted by sliding the installation block of the quick-release assembly so that the installation block slides in the slide groove, thereby being clamped and fixed with installation holes of different sizes.

[0007] Preferably, the quick-release assembly includes an adjustment seat and a torsion spring. The adjustment seat is provided with two groups and both are arranged on the surface of the base plate. The slide groove is provided with two groups and both are arranged on the surface of the adjustment seat. Both ends of the mounting block are slidably connected in the slide groove.

[0008] Preferably, the torsion spring is arranged in the mounting block and both ends of the torsion spring are connected with fixing ears.

[0009] Preferably, a plurality of slots are provided on the surface of the mounting block and between the two groups of slide grooves, an elastic clamping plate is provided at one end of the mounting block away from the fixing ear and an arc-shaped clamping block is provided at the bottom of the elastic clamping plate, and the arc-shaped clamping block is engaged with the slots.

[0010] Preferably, a power cord is fixed to the surface of the base plate via a wire buckle, and one end of the power cord passes through the base plate and is electrically connected to the lamp bead.

[0011] Preferably, a plurality of heat dissipation strips are provided on the surface of the bottom plate and a plurality of heat dissipation grooves are provided between the heat dissipation strips, so that the heat dissipated by the downlight is absorbed by the heat dissipation strips and the heat dissipation grooves are used to dissipate the heat, thereby preventing the temperature of the lamp beads from rising.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] Before installing the downlight, the position of the mounting block can be adjusted according to the size of the ceiling mounting hole, and the mounting block is pushed to move in the slide groove on the surface of the adjustment seat. While the mounting block moves, the elastic clamping plate drives the arc edge of the arc-shaped clamping block to contact the arc-shaped clamping groove, so that the elastic clamping plate can drive the arc-shaped clamping block to disengage from the clamping groove when moving, thereby driving the fixing ear and the torsion spring to move. After adjusting to the appropriate position of the mounting block, the arc-shaped clamping block is re-clamped with the clamping groove to limit the mounting block, thereby completing the adjustment of the fixing ear and the torsion spring position, so that the user can adaptively adjust the position of the fixing ear and the torsion spring according to the size of the mounting hole, thereby meeting different installation requirements.

[0014] When installing the downlight, use both hands to flip the two sets of fixing ears from the original horizontal state to the vertical state. The fixing ears will squeeze the torsion spring when flipping. After flipping, insert the two sets of fixing ears into the mounting holes on the ceiling surface, and remove both hands to reset the torsion spring. Thus, the fixing ears in the vertical state are reset to the horizontal state under the action of the torsion spring, and the fixing ears are snapped into the mounting holes on the ceiling surface to complete the installation, which is more convenient.

[0022] A downlight, the downlight comprises a lampshade 1 and an aluminum base plate 2, the lampshade 1 is arranged in an arc transparent shape and the aluminum base plate 2 is arranged in the lampshade 1, a plurality of lamp beads 3 are evenly distributed on the surface of the aluminum base plate 2, a base plate 4 is fixed to the top of the lampshade 1 by screws, a quick-install component 5 for installing the downlight is provided on the surface of the base plate 4, the mounting block 9 of the quick-install component 5 is slid so that the mounting block 9 slides in the slide groove 10 to adjust the mounting position of the mounting block 9, so as to be clamped and fixed with mounting holes of different sizes, the lampshade 1 is an acrylic translucent lampshade 1, and the base plate 4 is a thickened all-aluminum heat dissipation base plate 4.

[0023] The quick-release assembly 5 includes an adjustment seat 8 and a torsion spring 7. The adjustment seat 8 is provided with two groups and both are provided on the surface of the bottom plate 4. The slide groove 10 is provided with two groups and both are provided on the surface of the adjustment seat 8. Both ends of the mounting block 9 are slidably connected in the slide groove 10.

[0024] The torsion spring 7 is arranged in the mounting block 9 and both ends of the torsion spring 7 are connected with fixing ears 6 . The fixing ears 6 can be clamped in the mounting hole under the action of the torsion spring 7 .

[0025] A plurality of slots 11 are provided on the surface of the mounting block 9 and between the two groups of slide grooves 10 . An elastic clamping plate 12 is provided at one end of the mounting block 9 away from the fixing ear 6 , and an arc-shaped clamping block 13 is provided at the bottom of the elastic clamping plate 12 . The arc-shaped clamping block 13 is engaged with the slots 11 .

[0027] A plurality of heat dissipation strips 16 are provided on the surface of the bottom plate 4 and a plurality of heat dissipation grooves 17 are provided between the heat dissipation strips 16. The heat dissipated from the lamp beads 3 on the surface of the aluminum substrate 2 is absorbed by the heat dissipation strips 16 and then dissipated through the heat dissipation grooves 17. Thus, the heat in the downlight is dissipated in time to avoid the temperature of the lamp beads 3 from rising, thereby affecting its performance and life.

[0028] The free-opening frameless downlight can adjust the position of the mounting block 9 according to the size of the ceiling mounting hole before installing the downlight.

After adjusting to the appropriate position of the mounting block 9, the arc-shaped clamping block 13 is re-clamped with the clamping groove 11 to limit the mounting block 9, thereby completing the adjustment of the position of the fixing ear 6 and the torsion spring 7, so that the user can adaptively adjust the position of the fixing ear 6 and the torsion spring 7 according to the size of the mounting hole, thereby meeting different installation requirements.

[0029] When installing the downlight, use both hands to flip the two sets of fixing ears 6 from the original horizontal state to the vertical state. When the fixing ears 6 are flipped, the torsion spring 7 will be squeezed. After flipping, the two sets of fixing ears 6 are inserted into the mounting holes on the ceiling surface, and both hands are removed to reset the torsion spring 7. Thus, the fixing ears 6 in the vertical state are reset to the horizontal state under the action of the torsion spring 7, so that the fixing ears 6 are snapped into the mounting holes on the ceiling surface to complete the installation, which is more convenient.

[0030] The downlight has a frameless ultra-thin design, which is not restricted by the height of the ceiling, and has higher flexibility and applicability during installation. The frameless design is not limited to the luminous area, so that the lamp beads 3 can emit light over a large area, illuminating a wide range and providing brighter light.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
