-COB LED module, back lighting for light box or big size channel letter illumination
-Using innovative, patent pending CooChip® technology, the LED chip is attached and bonded directly to the aluminum PCB and heat-sink, resulting in ultra low heat resistance. CooChip® Runs COOL !
-Extended operating life at high ambient temperature, 75,000+ hrs @25℃ / 50,000+ hrs @40℃ for white LED modules
-178° wide angle, emits much softer, more even light compared to regular LED
-Minimum depth for channel letter or light box: 10cm(4 inch)
The LED chip is bonded onto aluminum PCB embedded in aluminum enclosure. Heat directly transfers to the substantial heat-sink. In typical modules relying on tiny LED lamp legs to transfer the same amount of heat, the results are much higher thermal resistance and excessive chip temperatures of 100℃+.
In addition, CooChip modules use thermal conductive tape to further assists heat dissipation.
The Life- Tj illustration demonstrates the relationship between life time and chip/junction temperature for typical LED chips. The lower the temperature, the longer the life. By using Coochip® technology, our LED modules have achieved the lowest possible chip temperature, thus prolonging its life even under high ambient temperatures.
The diagram below explains heat management comparison between Coochip Modules and Typical Modules.
