PRODUCT SPECIFICATION DATE: 03/08/2005 cosmo ELECTRONICS CORPORATION H.P LED : NO. 61L70020 KLH00BGA3 SHEET 1 OF 7 REV. 1 1. Features Cosmo’s high power LED packages can handle up to 350-500mA DC current, and available in 590nm, 525nm, and 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. o l 130±10 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.

Luminous intensity is measured with a photo detector and filter combination that follows the CIE ete - response curve. And the equipment measured luminous intensity torellance is ±5%. 2. θ1/2 is the off - axis angle at which the luminous intensity is half the axial luminous intensity. 3. The dominant wavelength, λd is derived from the CIE chromaticity diagram and represents the color of the device. 4. Caution in ESD: Static Electricity maybe cause damages to the LED. It is recommend to use a wrist band or anti - electrostatic glove when handing the LED. All devices, equipment and machinery must be properly grounded.
