Embodiment Construction
[0039] 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.
[0040] 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 .
[0041] 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, ...

The invention relates to a light-emitting diode (LED) tube lamp, which comprises a lamp body, an LED light-emitting module and a power supply module. The lamp body comprises a tube body, a cover plate and a radiating body. One end of the tube body is opened, and the other end of the tube body is covered by the cover plate. The inner surface of the cover plate is used for arranging an LED light-emitting module of the LED tube lamp, and the radiating body is formed on the outer surface of the cover plate. The radiating body comprises a protruding column and a plurality of radiating fins, wherein the protruding column is arranged corresponding to the LED light-emitting module; the radiating fins are arranged on the outer surface of the cover plate by surrounding the protruding column; and each radiating fin extends along the radial direction of the tube body from the outer surface of the protruding column. The protruding column is arranged corresponding to the position of the LED light-emitting module, and can quickly absorb the heat generated by the LED light-emitting module. The radiating fins are connected with the protruding column, and can quickly transfer the heat from a heat concentrated area at the LED light-emitting module to the radiating fins. As a result, the heat generated by the LED light-emitting module can be radiated more quickly.
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, short lamp life, and insufficient softness of 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. However, due to the use of high-power LEDs as light sources, their heat generation is greater than that of ordinary low-power LEDs, and after long-term use, the temperature inside the lamp increases, which in turn leads to an increase in the internal thermal resist...
