Problems solved by technology

However, due to the very limited space of the LED lamp itself, the cooling box is used to seal the heat dissipation liquid and also takes up a lot of internal space, which also increases the difficulty of product design and installation

Embodiment Construction

[0028] specific implementation plan

[0029] Such as figure 2 As shown, it is the first embodiment of the present invention. The embodiment of the present invention provides a liquid-cooled LED lighting lamp, including a plug-in electrical connector 1, an LED power supply 2, a lamp holder 4, a heat dissipation lampshade 6, and an aluminum substrate 7 , LED 8, astigmatism lampshade 9. The electrical connector 1 is set on the lower part of the LED lamp cap to connect to the mains, and it is connected to the input of the LED power supply 2. The heat dissipation lampshade 6 is equipped with a high-performance heat-conducting liquid, and the LED power supply 2 is arranged on the heat dissipation lampshade. In the space formed by the upper lamp holder 4 of the partition plate 3 of 6, the LED 8 is arranged on the LED aluminum substrate 7, the periphery of the LED aluminum substrate 7 is closely connected with the lower end of the heat dissipation lampshade 6, and the LED 8 is place...

Abstract

The invention discloses a liquid cooling LED lamp, comprising an electrical connector, a power supply, a lamp socket, a heat radiating lamp cover, an LED installation base plate, an LED and a light diffusion lamp cover at the lower part; wherein, the light diffusion lamp cover is made by nearly transparent material. The invention is characterized in that the light diffusion lamp cover is filled with heat conducting liquid. As the liquid cooling LED lamp luminaire is equipped with high performance heat conducting liquid (such as water, heat conducting oil, saltwater, glycol solution, dipivaloylmethane saturated solution and the like), the heat conducting is realized by conduction and convection to obtain good heat radiating effect. Meanwhile, the radiating lamp cover filled with high performance heat conducting liquid can be made by light weight materials, therefore, the radiating body is light in weight, environmentally-protective, durable in use, simple in production and low in cost.

Description

technical field [0001] The invention relates to an LED lamp, in particular to an LED lamp which uses liquid to help dissipate heat. Background technique [0002] With the development and maturity of high-power LED technology, the performance index of LED for lighting has been greatly improved day by day. At present, the luminous efficiency of industrialized white LEDs has reached (70-90) lm / W, far exceeding the luminous efficiency level of ordinary incandescent lamps. High-power LEDs will be more and more widely used in the field of lighting. It is the fourth-generation lighting source that replaces fluorescent lamps and incandescent lamps in the 21st century. [0003] However, since the LED must be below 80 degrees Celsius to obtain high light efficiency and long life, the thermal design requirements for LED lamps are very high. Poor heat dissipation will cause LED light decay, reducing luminous efficiency and service life. In order to obtain a good heat dissipation effe...
