PRODUCT SPECIFICATION DATE: 06/12/2008 cosmo H.P LED : NO. 61L70035 KLE06WXX4 ELECTRONICS CORPORATION SHEET 1 OF 6 REV. 1 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： z Very high flux output per LED. z 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. z Very long operation life time up to 100k hours attainable, by using a proper heat sink. o z 120±10 cool beam in most packages. 2. Applications z z z z z z z z z 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.
