Han Yee, director of lighting marketing at Optima, said that heat dissipation has always been a hidden secret of LED lighting. It can be counted: because of the heat dissipation problem, the junction temperature is too high, the attenuation is fast, and the life is short; because of the heat dissipation problem, the ambient temperature cannot be too high or too low; because of the heat dissipation problem, it cannot be used in a dusty environment; There is not much room for choice; because of the heat dissipation problem, the volume is difficult to make small; because of the heat dissipation problem, the lumen number is difficult to improve; because of the heat dissipation problem, the LED light is difficult to waterproof and so many other problems are all around the LED heat dissipation.
Han Yiwei said that Uglia has boldly tried to abandon the traditional thinking of heat dissipation and air cooling of aluminum fins, using the patented liquid cooling technology of insulation, flame retardant, non-toxic, non-corrosive, safe and environmentally friendly, so that the LED light-emitting chip and the driving circuit are all immersed in the liquid. In the middle, it solves the most important heat dissipation problem affecting LED life.
The liquid cooling method is adopted to dissipate heat rapidly, so that the working temperature of the whole lamp chip is below 65 ° C, which slows down the light decay of the lamp bead and prolongs the service life of the lamp. It is unmatched by other heat dissipation methods. Due to the principle of subverting the traditional cooling technology, it brings multiple advantages such as small size, long life, excellent optical index and strong environmental suitability. 
Han Yiwei: Liquid cooling is an efficient way to solve LED heat dissipation
