Cree(R) XLamp(R) 4550 LEDs
Binning and Labeling
Cree XLamp 4550 LEDs combine the brightness of power LED chips with a rugged package capable of operating in excess of half of a watt. XLamp LEDs lead the solid-state lighting industry in brightness while providing a reflow solderable design that is optimized for ease-of-use and thermal management. Lighting applications featuring XLamp LEDs maximize light output and increase design flexibility, while minimizing environmental impact.
This application note describes Cree's procedures for sorting XLamp 4550 LEDs by color (dominant wavelength) and brightness (luminous or radiant flux) and then lists the order codes encompassing these color and brightness groups for easy reference.
Nomenclature
XLamp LEDs are tested and sorted into performance bins. A bin is specified by ranges of dominant wavelength and brightness. Sorted XLamp LEDs are packaged on reels. A reel contains lamps from one bin and is labeled with its bin code. For more information on packaging see the XLamp 4550 Data Sheet.
XLamp LEDs are sold by order codes in combinations of bins called kits. Kits include a minimum of two dominant wavelength groups and two brightness groups. Order codes are configured in the following manner:
Kit # Combination of bins 0001-9999
Family XL4550
Color ROY BLU GRN AMB
Spatial Pattern L - Lambertian
Viewing Angle (degrees) 100
.00 ote: CLD-AP0 Application N
RED
XLamp LED order codes specify package family, color, optical configuration (spatial pattern and viewing angle) and kit number (combination of bins). Kit number 0001 is always the order code encompassing the broadest range of color and brightness groups.
