Problems solved by technology

However, today's high-brightness LEDs generate relatively large local heat. If they want to replace CCFL as lighting products, they must have a suitable heat dissipation design; otherwise, it will cause problems such as reduced LED luminous efficiency and shortened life. Metal Core Print Circuit Board (MCPCB) is often used as the heat dissipation medium, but LEDs still cannot be installed in a high-density manner, because the heat dissipation capacity cannot be effectively broken through, so the heat dissipation of LEDs is currently a problem that the industry needs to overcome.

Embodiment Construction

[0013] Such as Figure 1 to Figure 4 As shown, the LED lamp of the present invention includes an LED module 100 and a heat dissipation module 200 for supporting and cooling the LED module 100 . In order to prevent dust and insects from affecting the service life of the LED module 100 , a lampshade 400 can be arranged on the heat dissipation module 200 and accommodate the LED module 100 therein. The lampshade 400 is usually made of transparent plastic, glass or other materials.

[0014] The heat dissipation module 200 includes a heat dissipation portion 210 located outside the lampshade 400 , a heat absorption portion located inside the lampshade 400 , and a heat pipe 270 . Two ends of the heat pipe 270 are respectively connected to the heat absorption portion and the heat dissipation portion 210 .

[0015] The heat dissipation portion 210 is roughly cylindrical in shape, and includes a cylindrical base 212 and a plurality of heat dissipation fins 214 radially extending from t...

Abstract

A light emitting diode lamp comprises a lamp cover, a plurality of light emitting diodes located in the lamp cover and a radiating module, wherein the radiating module comprises a heat absorption portion located in the lamp cover, a radiating portion located outside the lamp cover and a heat pipe connecting the heat absorption portion and the radiating portion. The radiating portion comprises a hollow base and a plurality of radiating fins arranged on the base. The heat pipe penetrates through the base of the radiating portion and the heat absorption portion, and is tightly wrapped by the base of the radiating portion and the heat absorption portion. The heat absorption portion is equipped with the light emitting diodes. The heat pipe is wrapped by the radiating portion and the heat absorption portion, thereby increasing the contact area among the heat pipe, the radiating portion and the heat absorption portion, and favoring the heat exchanging among the heat pipe, the radiating portion and the heat absorption portion. The heat pipe can be sufficiently utilized to fast transfer the heat generated by the light emitting diodes to the radiating portion, thereby increasing the radiating efficiency of the radiating module.

Description

technical field [0001] The invention relates to a light-emitting diode lamp, in particular to a light-emitting diode lamp with a heat dissipation module. Background technique [0002] With the advancement of science and technology, the development from general tungsten filament lamps to the current Cold Cathode Fluorescent Lamp (Cold Cathode Fluorescent Lamp, CCFL) and Light Emitting Diode (Light Emitting Diode, LED) are all developing in the direction of volume reduction and flattening. [0003] At present, CCFL can hardly be reduced because of its size, and CCFL will interfere when boosted to 600 volts. In addition, CCFL will cause mercury pollution, so some countries will also ban it. LED has many characteristics such as environmental protection, high brightness, power saving, long life, etc., so LED will gradually replace CCFL. However, today's high-brightness LEDs generate relatively large local heat. If they want to replace CCFL as lighting products, they must have a ...
