1. Features
Cosmo’s high power LED packages can handle up to 350-500mA DC current.
These packages are formed by bonding 4 pcs of 40 mil LED chips on a
20mmx20mm metal PCB. A heat sink is mechanically screwed to the board to
cool down metal surface temperature below 70 oC. The main features of these
packages are as follows:
l Very high flux output per LED.
l Flat PCB package. On each PCB, the quantity of LED being adjustable from
1 to 4 to meet user’s need. These LEDs being connected in series.
l Very long operation life time up to 100k hours attainable, by using a proper
heat sink.
o
l 130±10 cool beam in most packages.
