1. Features
Cosmo’s high power LED packages can handle up to 350-500mA DC current, and
available in 625nm wavelength in mono or multiple colors. 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 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 3 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.
