Radiation Cooling Effect of LED Lamp by Radiant Materials based on Polar Crystal Metals

Abstract

Experiments have been carried out to examine the fundamental characteristics of radiation cooling of new radiant materials developed for the study based on the polar crystal metals. In addition, the basic performance for the radiation cooling of LED lamp and LED fluorescent light haven been also investigated using the new radiant materials. The acquisition obtained for the studies shows that the radiation effect of new radian materials is superior to those of existent radiation paints such as alumite and high efficiency heat radiation paints. And the rate of temperature drop of diode on LED lamp and LED fluorescent light can be estimated as 10%. Where, the new radiant materials are produced by mixing nano-size crystal metals into high efficiency heat radiation paints. This concept is caused by the increase of surface area due to the rough surface generated by nano-size crystal metals.
