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).

Q:What is the role of LED downlight
Compared with other lamps, it is the main installation can be embedded into the ceiling will not affect the overall appearance but also has installed more than spot downlight, past ordinary lamps, in fact is the common use of lighting or other auxiliary lighting, general store with more traditional can replace the lamp
Q:LED lamp power off why would light up
LED lights turn off the light: 1, the switch is cut off the zero line, you can change the line.2, share change in induction. Switch off zero line with switch.No electricity and no effect on the light, so ignore it.
Q:The difference between ordinary LED lamp and LED downlight and integration of advantages and disadvantages
Can work in a high-speed state: energy-saving lamps if frequent start or turn off, the filament will blacken, quickly damaged
Q:Common questions about LED downlight spotlights
Currently on the market Jiezhuang LED downlight is 12--24 DC drive, just some built-in drive, directly connected to the 220V power supply, there is need to use power.
Q:LED downlight, embedded lamps, lamp tube and difference?
No LED lamp lens, no light, light uniformity, light angle.LED recessed lamp is in accordance with the method, there are two types of installation and embedded installation. The recessed lamp is mounted inside the ceiling.LED cylinder spotlights have lenses, focus light, first focus on a place to illuminate, and where the illumination is high.
Q:What brand of downlight is good? Please explain the reason, thank you!
After-sale service。 Before buying, it is best to know how long the warranty period is for the product. Some of the poor products are only guaranteed for one year. That is almost the same as the traditional energy-saving lamp. The price is still expensive, and it is not worthwhile.
Q:7 square feet of aisle to install 3 LED downlight, how much w led downlight
5W*3, the key depends on the ceiling elevation.You can use 3 W
Q:Why use LED lamp light source patch
In a large number of automated production, the packaging cost of the patch LED itself and the cost of soldering to the circuit board are lower than those of the small power LED.
Q:How much is the general 15WLED lamp luminous flux.
Look at the product parameters, and if it's done with a single 1W, it's probably around 1600LM,
Q:Steam more business bathroom bath with what LED lamp?
Select a special waterproof steam lamp can, general ceiling lamp with more. I hope my answer can help you, I hope to adopt!
