technical field [0001] The invention relates to the technical field of radiators, in particular to a heat pipe radiator. Background technique [0002] With the development and maturity of LED technology, the performance index of LED has been greatly improved day by day, and it has been widely used in the field of lighting. Compared with the lighting fixtures used with general photovoltaic power sources, LED has the outstanding advantages of long life, low heat generation, not easy to damage, low power consumption and more energy saving. [0003] At present, when using light-emitting diodes, a plurality of light-emitting diodes are usually installed on an aluminum substrate in a prescribed manner to form a light-emitting diode module, and the heat is conducted through the heat-conducting surface of the aluminum substrate to the lamp housing for heat dissipation. In order to meet the heat dissipation requirements, it is often necessary to increase the heat dissipation area of...

AI Technical Summary

Problems solved by technology

In order to meet the heat dissipation requirements, it is often necessary to increase the heat dissipation area of ​​the lamp shell, which increases the weight of the entire lighting fixture on the one hand, which is inconvenient to use, and on the other hand, it will inevitably increase the manufacturing cost.

Especially for high-power LEDs with a power of several watts to hundreds of watts used in lighting, if no heat dissipation measures are taken, the junction temperature of the LED chip will rise rapidly, resulting in a sharp decrease in the light output rate and life of the LED, especially when the junction temperature When rising above the maximum allowable temperature, the LED will fail due to overheating

The currently used LED heat dissipation technology solutions have various defects and deficiencies such as poor heat dissipation effect and poor reliability, which greatly limit the wide application of high-power LED lights.
