Description

Technical Field

[0001] The present application relates to the technical field of lamps, and in particular to a downlight reflector system and an installation method thereof. Background Art

[0002] A lamp is a structure used for lighting and decoration. There are many types of lamps, among which downlight is one of the lamps. It is usually embedded in the ceiling and radiates light downward, which has good lighting effect and aesthetics.

[0003] Current downlights generally include a lamp body, a light source structure disposed at the bottom of the lamp body, and a reflector cup fixed at the bottom of the lamp body and covering the light source structure. Among them, the reflector cup is a kind of reflective device. The reflective device refers to a light reflector that controls the illumination distance and illumination area of ​​the main light spot in order to utilize limited light energy. The reflector cup refers to a reflector that uses a point light bulb as a light source and requires long-distance focusing illumination. It is usually cup-shaped and commonly known as a reflector cup. However, since most of the reflector cups of current downlights use mirror effects or sand effects on the surface, too smooth mirror surfaces will cause concentrated light reflection to produce glare, and although too rough sand surfaces can scatter part of the light and reduce glare, they will also reduce the light reflection efficiency, thereby affecting the light output rate. Summary of the invention

[0004] In order to effectively reduce glare or low light output when downlights are illuminated, and to improve the illumination effect of the reflective cup, the present application provides a downlight reflector system and an installation method thereof.

[0005] In a first aspect, the present application provides a downlight reflector system, comprising a light source, a reflective cup and a lampshade, wherein one side of the reflective cup is detachably connected to the light source via a first mounting member, and the other side of the reflective cup is detachably connected to the lampshade via a second mounting member, and a lens is further mounted on one side of the reflective cup via the second mounting member, a plurality of first protrusions are arranged on the inner side of the reflective cup, and a plurality of second protrusions are arranged on the side of the lens close to the reflective cup.

[0006] By adopting the above technical solution, the light emitted from the light source will be reflected in the reflective cup, thereby enhancing the brightness of the light and making the light brighter. At the same time, the divergence of the light can be better reduced by setting the lens and the lampshade. The lampshade can also prevent the user from directly contacting the hot light source by using it in conjunction with the reflective cup, thereby reducing the risk of burns. In addition, the present application helps to improve the light control ability by respectively setting multiple first protrusions and multiple second protrusions on the reflective cup and the lens, which can change the reflection angle of the light, make the light more orderly when reflected, reduce multiple reflections and scattering of the light inside the downlight, thereby improving the directness and concentration of the light, and regularly diffuse the light, thereby achieving a better light mixing effect, which is conducive to providing better light spot uniformity, achieving the purpose of reducing glare while ensuring better light output efficiency.

[0007] Optionally, a plurality of the first protrusions are evenly and closely arranged along the inner wall of the reflective cup.

[0008] Optionally, the plurality of first protrusions are all configured to be rectangular.

[0009] By adopting the above technical solution, the closely arranged multiple first protrusions enable the light to be effectively reflected at multiple positions on the inner wall of the reflective cup. At the same time, the rectangularly arranged first protrusions can shape the light so that the light forms a specific beam distribution when it is emitted, thereby forming a more uniform light spot and a more concentrated light beam, thereby achieving the purpose of reducing glare caused by excessive divergence of light.

[0010] Optionally, a plurality of the second protrusions are closely arranged on the side wall of the lens in a spiral shape.

[0011] Optionally, the plurality of second protrusions are arranged in a hexagonal shape.

[0012] By adopting the above-mentioned technical solution, multiple second protrusions that are tightly arranged in a spiral shape can distribute light more evenly on the surface of the lens, reduce light spots and shadows, and achieve a softer and more uniform lighting effect, thereby making the emission of downlight light softer and improving the visual effect of lighting. At the same time, by restricting the shape of the second protrusions, the surface area of ​​the lens surface is increased, which can also help dissipate heat and improve the heat dissipation efficiency inside the downlight of the present application.

[0013] Optionally, the first mounting member includes a first connecting ring seat and a first connecting buckle, the first connecting ring seat is arranged on one side outer wall of the reflective cup, the connecting buckle is arranged on the side wall of the first connecting ring seat and is engaged and positioned with the light source to assemble the light source and the reflective cup.

[0014] By adopting the above technical solution, the first connecting ring seat can be tightly pressed against the side of the light source, and then the first connecting buckle is clamped inside the light source, thereby realizing rapid assembly of the light source and the reflective cup.

[0015] Optionally, the second mounting member includes a second connecting ring seat and a second connecting buckle, the second connecting ring seat is arranged on an outer wall of one side of the reflective cup and abuts against an inner wall of the lampshade, and the second connecting buckle is arranged on a side wall of the lens and is engaged and positioned with the second connecting ring seat to realize the assembly of the lampshade, the reflective cup and the lens.

[0016] By adopting the above technical solution, the second connecting ring seat can realize the positioning and assembly of the reflective cup and the lens by snapping and positioning with the second connecting buckle, and then the inner wall of the lampshade is pressed against the inner wall of the second connecting ring seat, thereby realizing the quick assembly of the lampshade, the reflective cup and the lens. At the same time, by making the lens stably installed as a whole between the reflective cup and the lampshade, the light output from the reflective cup can be reflected for the second time, thereby further improving the concentration and efficiency of the light irradiated by the downlight of the present application.

[0017] In a second aspect, the present application provides a method for assembling a downlight reflector system, comprising the following steps: The reflective cup is mounted to the light-emitting side of the light source through the first mounting member, and the light-emitting side of the light source is made to face the plurality of first protrusions on the inner side of the reflective cup; The lampshade and the lens are assembled on the other side of the reflective cup through the second mounting piece, and the plurality of second protrusions are made to face the plurality of first protrusions, thereby completing the installation of the downlight.

[0018] By adopting the above technical solution, quick assembly of the light source, reflector cup, lens and lampshade is achieved, thereby improving the efficiency of disassembly and assembly during subsequent maintenance and replacement. At the same time, the light emitted by the light source can be reflected by the first protrusion and the second protrusion in sequence, so as to effectively improve the uniformity of the light spot and the light output efficiency of the downlight of the present application during irradiation, thereby achieving the purpose of reducing glare caused by excessive divergence of light.

[0019] In summary, the present application includes at least one of the following beneficial technical effects: 1. By making the light emitted from the light source be reflected in the reflective cup, the brightness of the light is enhanced, making the light brighter. At the same time, the divergence of light is better reduced by setting the lens and the lampshade. The lampshade can also prevent users from directly contacting the hot light source by using it in conjunction with the reflective cup, thereby reducing the risk of burns. In addition, the present application is conducive to improving the light control ability by setting a plurality of first protrusions and a plurality of second protrusions on the reflective cup and the lens respectively, and can change the reflection angle of the light, so that the light is more orderly when reflected, and reduce the multiple reflections and scattering of the light inside the downlight, thereby improving the directness and concentration of the light, so as to diffuse the light regularly, thereby achieving a better light mixing effect, which is conducive to providing a better light spot uniformity, and achieving the purpose of reducing glare while ensuring better light output efficiency; 2. Through the closely arranged multiple first protrusions, the light can be effectively reflected at multiple positions on the inner wall of the reflective cup. At the same time, the rectangular first protrusions can shape the light so that the light forms a specific beam distribution when it is emitted, thereby forming a more uniform light spot and a more concentrated beam, thereby achieving the purpose of reducing glare caused by excessive divergence of light; 3. Through the multiple second protrusions tightly arranged in a spiral shape, the light can be distributed more evenly on the surface of the lens, reducing light spots and shadows, achieving a softer and more uniform lighting effect, thereby making the emission of the downlight light softer and improving the visual effect of the lighting. At the same time, by limiting the shape of the second protrusions, the surface area of ​​the lens surface is increased, which can also help dissipate heat and improve the heat dissipation efficiency of the downlight inside the present application; 4.
