1. Features
Cosmo’s high power LED packages
can handle up to 350-500mA DC current,.
These packages are formed by bonding 2~4 pcs LED chips on a 9.2*8mm metal
PCB. The main features of these packages are as follows：
Very high flux output per LED.
Flat PCB package. On each PCB, the quantity of LED being adjustable from
2 to 4 to meet user’s need. These LEDs being connected in series.
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
