1. Features
Cosmo’ high power LED packages
can handle up to 350-500mA DC current.
s
These packages are formed by bonding 3 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
o
C
. 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 3 to meet user’ need. These LEDs being connected in series.
s
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.
