Lighten Technology is located in Taiwan,focusing on the technical development and production of high-power copper-substrate COB light sources.Our copper-substrate uses a unique surface anti-sulfur technology,which enables high wattage COB light sources with high light efficiency and low The characteristics of light decay, anti-oxidation and anti-vulcanization to improve the market value of customers.
Core Technology
Low thermal resistance<0.16°C/W
High thermal conductivity 401W/(m.K)
High thermal conductivity 401W/(m.K)
LED chip is directly bonded to the copper substrate
Unique surface reflective technology
No silver plating process,No vulcanization,Using aerospace-grade materials to achieve ultra-low light attenuation
Special anti-oxidation treatment at the bottom of the copper substrate
High Weather Resistant Material System
Can be used in harsh environments(High temperature, high humidity, high vulcanization)
Other COB use silver-plated aluminum substrate after 168 hours of lighting
The board turns black due to oxidation and vulcanization

Lighten COB after 2000 hours of lighting
No oxidation and sulfuration blackening
Other COB after 300 hours of lighting, the light decay exceeds 50%
Lighten COB after 1500 hours of lighting, the light decay does not exceed 3%
