At present, the biggest technical problem of LED lighting is the problem of heat dissipation, which leads to LED driving power and electrolytic capacitor as the short board for the further development of LED lighting fixtures. The space of traditional lamps and lanterns is narrow and small.
At present, after the LED light source is on power, about 30% of the electric energy is converted into light energy, and the rest is converted into heat energy. Therefore, it is the key technology for the structure design of LED lamps to export so much heat energy as soon as possible. Heat energy needs to be emitted through heat conduction, thermal convection and heat radiation. Only when the heat is exported as soon as possible can the cavity temperature in the LED lamp be reduced effectively in order to protect the power supply from working in a lasting high temperature environment, and to avoid the premature failure of the LED light source because of the long-term high temperature work.
LED radiator 1
Looking for simple and easy to use, good thermal conductivity, and low cost heat dissipation material has been our pursuit. On the market, it is often used to squeeze aluminum heat sink as LED luminaire for heat dissipation. Its principle is to squeeze liquid aluminum through a fixed mold, and then cut the bar into a desired shape of the radiator, and then after the deep processing. Extrusion of aluminum radiator, its fin can be done a lot of very thin, the maximum expansion of heat dissipation area, heat dissipation wing automatically forms the air convection heat, heat dissipation effect is very good.

What are the advantages of using aluminum profile as radiator for comparison with other materials? Such as energy saving, material saving, decoration, price, weight, and so on. The high thermal conductivity of aluminum profiles is the decisive factor for maintaining good heat dissipation function and the most ideal medium for thermal energy conversion. The characteristics are: less time, fast heating, high efficiency, light and smart, and easy to process is a major feature. The radiator of the same specification, the weight of the aluminum profile is 1/3 of the steel radiator.
