LED downlight description:

  1. Using nonconductive silicone to bring the heat from chip to the radiator quickly.

  2. With the unique design of the independent intellectual property rights of the integrated radiator and shell, it’s possible to realize the heat conduction and air convection.

  3. It adopts the world’s leading high-quality LED chips and driver.

  4. All the COB LED use integrated high power light source.

  5. The Downlight have a lifespan of 50,000 hours. 


LED downlight applications:


Hotel, supermarket, factory, subway, hospital, school, meeting room, office, housing, etc.

World Leading Heat Dissipation Technology---Only one piece of “BLACK SLICE” could replace the primitive heat dissipation-Thermally Conductive Silicone and greatly increase LED Downight Lifespan.





*A special Zero-heat capacity in composited material using Nanotechnology.

*The heat of P-N Junction is diffusing at a speed of microsecond unceasing, thus lowers the

junction temperature drastically.

*The heat from the light source escapes to the radiator in the way of heat exchange between

positive and negative electron in wave patterns.

*Non-Volatile and long lifespan. 


The shortcoming of Thermally Conductive Silicone:


*Volatile, result in a thermal resistance

*Easy to aging

*Difficult to plastering

*Low thermal conductive coefficient (1-3w/m.k) compare to our “BLACK SLICE” thermal  diffusivity (200-300w/m.k, 260m^2/s).
