Embodiment Construction

[0041] Specific embodiments of the present invention will be described in further detail below based on the accompanying drawings. It should be understood that the specific embodiments described here are only examples, and are not intended to limit the protection scope of the present invention.

[0042] see figure 1 and figure 2 , The LED downlight 100 provided by the first embodiment of the present invention includes a lamp body 10 , a power supply module 20 , an LED lighting module 30 , a reflector 40 and a lampshade 50 .

[0043] see further image 3 and Figure 4 , the lamp body 10 includes a cylinder body 11 , a cover plate 12 and a radiator 13 . In this embodiment, the lamp body 10 is integrally formed, so that the heat generated by the LED light-emitting module 30 can be dissipated through the cylinder body 11, the cover plate 12 and the radiator 13 of the lamp body 10, which greatly improves the performance of the LED downlight. 100% heat dissipation efficiency, ...

Abstract

The invention relates to a lamp body of an LED downlight, which comprises a cylinder body, a cover plate and a radiator. One end of the barrel is open, the other end is covered with the cover plate, and the radiator is formed on the outer surface of the cover plate. The cylindrical body includes a first cylindrical portion connected to the cover plate and a second cylindrical portion connected to an end of the first cylindrical portion away from the cover plate. A stepped surface facing the opening direction of the cylinder body is formed between the inner surfaces of the first cylinder part and the second cylinder part. An annular groove and a plurality of fixing holes are formed on the step surface. The lamp body can be matched with the traditional LED lamp board, and also can be matched with the integrated LED light source, which has strong compatibility. In addition, the present invention also provides an LED downlight having the above-mentioned lamp body.

Description

technical field [0001] The invention relates to a lighting fixture, in particular to an LED downlight and a lamp body thereof. Background technique [0002] Downlight is a downlight lighting fixture installed on the roof, which is widely used in shopping malls, hotels, large supermarkets, schools, hospitals, etc. Downlights that use metal halide lamps or fluorescent lamps as light sources have high power consumption, long lamp life, and insufficient light color. [0003] A light emitting diode (Light Emitting Diode, LED) light source has high luminous efficiency, soft light color, low power consumption, and long service life, which can improve some shortcomings of traditional light source downlights. [0004] However, LED light sources currently on the market generally include integrated LED light sources and LED light panels. The integrated LED light source has only one light-emitting area, and the light is relatively concentrated, similar to a point light source. In appl...
