Heat pipe in high-power LED lighting application

Since the heat pipe evaporator and condenser sections are in the form of latent heat transfer, so with silver, copper and aluminum and other metals than the unit mass of the heat pipe can be several orders of magnitude more than the heat transfer. , The design of the LED heat sink above the LED heat pipe varying thermal path, the heat transfer through the heat pipe to the LED side, cooling fins can be extended to the lower portion, the use of a lower space, the heat radiating area can be increased about twice.

Thermal path flexibility allows heat pipe heat sink area is greater and therefore the same weight lamps. Using heat pipe cooling area can be done relatively larger to carry more power to the LED.

With the rapid development of LED lights, Angle beam LED lighting advantage as increasingly was reflected. But the high-pressure sodium lamps still account for a large market, if abandoned the original lights to LED lights, is bound to cause great waste of resources, there is no one product can achieve the effect of efforts to save energy but also take advantage of the existing lighting products it? The following products give us an idea of ​​This product is the use of the characteristics of making a heat pipe heat pipe radiator with LED installed in existing fixtures, through the heat pipe is located within the reflector LED heat transfer to the outer distributed out. This structure of the LED installation of unloading is more convenient. Heat pipes and reflectors on supporting lamp holder, just like an ordinary sodium light bulb installed (see Figure III), extends the linear LED lighting holder can be screwed inside. Full use of the existing street lighting reflector, can produce good quality of lighting.

Through the heat pipe for LED lighting analysis, heat pipe can fundamentally solve the large volume of existing LED lights; cooling capacity is not glaring shortcomings. And the heat pipe thermal path is more flexible, especially in the case of the products mentioned in this article, both play the advantages of energy-saving LED lights, but also retain the existing street resources, avoid duplication of investment and waste.
