PRODUCT SPECIFICATION DATE: 03/08/2005 cosmo H.P LED : KLH00BXX3 ELECTRONICS CORPORATION NO. 61L70003 REV. 1 SHEET 1 OF 6 1. Features Cosmo’s high power LED packages can handle up to 350-500mA DC current, and available in 470nm 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. l 130±10o cool beam in most packages. 2. Applications l l l l l l l l l 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 Light guide 3.
