COB Power LED Optical Light Source With Aluminum Base

Brief Description Of COB Power LED Optical Light Source With Aluminum Base

1. Raw Materials:
   • CHIPS: USA Bridge-lux/Taiwai Epistar/Taiwai Epiled
   • LED Base: Aluminum Base(Low cost planar, thermoelectricity separation comes true)
   • Gold Wire: German Heras 1.5u 99.99% pure gold wire (can bear bigger current, has less electricity resistance)
   • Fluorescent Powder: USA Intermatix ( for high performance in brightness)
   • Silica Gel: USA Dowcorning (has less light decreasing)
   • Circuit Layer Board: FR-4, withstand voltage, heat resistance
2. Luminous Efficiency:100lm/w(CRI=80-95Ra)  50,000H lifespan,3 years warranty 
3. Through multi-chip combination, quantity of heat can be shared by every high power chip
4. Little light decreasing , thermal resistance can be reduced by highly-efficient heat exchange because chips get in touch with Aluminum Base straightly
5. Emitting color: Pure white and warm white
6. Sensitive to ESD
7. COB encapsulation type, Fluorescent gel can be fulfilled in the bowl-cup
8. All products aging more than 8 hours before shipment to ensure reliable quality
9. Providing technical support, such as choice of heat-sink, driver or lens
10. Applications:
    Widely applied in lighting
    • Instead of the fluorescent lights indoors 
    • Spot light
    • Down light/Ceiling light
    • Ball bulb
    • Panel light
