technical field

The utility model relates to a downlight, in particular to a light-emitting diode downlight.

Background technique

As a decorative lighting product, the downlight has a wide range of uses. The light source of the existing downlight is an ordinary light bulb or an energy-saving light bulb, which has the disadvantages of low light efficiency, large power consumption, high use cost, and ultraviolet radiation.

Contents of the invention

The purpose of the utility model is to provide a high-power light-emitting diode downlight with high light efficiency, minimal power consumption, long service life, no ultraviolet radiation, compact and reasonable structure, and environmental protection.

In order to achieve the above object, the utility model is achieved through the following technical solutions. High-power LED downlight, including lamp housing, spring clip, high-power LED light source, LED driver, heat dissipation bracket and aluminum substrate, high-power LED light source is installed on the aluminum substrate and located on the inside of the top of the lamp housing, the aluminum substrate and The lamp housing and heat dissipation bracket are tightly fixed by plane contact, and the LED driver is connected with the high-power light-emitting diode light source through wires and fixed in the heat dissipation bracket.

The high-power LED downlight also includes a plane reflector, the plane reflector is arranged on the inner side of the top of the lamp housing, and has a light hole matching the high-power LED light source, and the high-power LED light source adopts a surface mount method Fixed on a circular aluminum base plate, the number is 1 to 6 in symmetrical distribution.

In the high-power LED downlight, the heat dissipation support adopts an aluminum 1mm thick square tube, and the space between the lamp housing, the aluminum substrate and the heat dissipation support is filled with heat-conducting silicon grease and tightly fixed with screws.

The high-power light-emitting diode downlight is provided with partially frosted glass on the light-emitting surface, the top of the lamp housing is circular, slightly larger than the aluminum substrate, and the waist adopts an arc-shaped curved surface.

Compared with the prior art, the utility model has the following advantages. (1) Because the light source of the downlight adopts high-power light-emitting diode LED, it has the advantages of high light efficiency, minimal power consumption, long service life, no ultraviolet radiation, and environmental protection; (2) It is due to the configuration of a flat reflector , the light output efficiency is greatly improved; (3) because the cooling bracket adopts aluminum 1mm thick square tube, its thermal conductivity and specific heat capacity are high, and the surface area is large, which can be used not only for heat dissipation, but also as a fixed bracket for LED driver; (4) is Because the lamp housing, aluminum base plate and heat dissipation bracket are in plane contact, and are filled with heat-conducting silicone grease and fixed tightly with screws, the thermal resistance is very small; (5) because the light-emitting surface is provided with partial frosted glass, which is both beautiful and prevents glare produce.
