1. Features
Cosmo’s high power LED packages
can handle up to 350-500mA DC current,.
These packages are formed by bonding 1 pcs LED chip on a
Φ8mm
Emitter.
The
main features of these packages are as follows：
Very high flux output per LED.
Very long operation life time up to 100k hours attainable, by using a proper
heat sink.
120±10
o
cool beam in most packages.
2. Applications
Outdoor and indoor architectural lighting
Reading light (car/bus/aircraft)
Decorative/entertainment lighting
Bollards/Security/Garden lighting
Traffic signal
Portable lighting (flashlight/bicycle)
Edge-lit signs (exit sign/point of sales)
LCD backlights
