XLamp® LEDs Overview
 |
|
Cree XLamp LEDs combine the brightness of power LED chips with a rugged
package. They lead the solid state
lighting industry in brightness while providing a reflow-solderable design
that is optimised for ease of use and thermal management. Lighting applications
featuring XLamp LEDs maximize light output and increase design flexibility, while minimizing environmental impact.
Cree XLamp LEDs bring lighting-class brightness and efficiency to a wide range of
lighting and backlighting applications, including portable lighting and flashlights,
outdoor and industrial, signalling, architectural, landscaping and entertainment /
advertising installations.

Cree Product Characterisation Tool (PCT)
 |
The Cree Product Characterisation Tool (PCT) allows you to select from multiple lighting-system design parameters to compare up to three LED models simultaneously.
For all valid LED drive currents, the PCT quickly and easily does the following:
- Shows all critical LED design parameters, such as luminous flux and efficacy, for selected LED models
- Performs de-rating calculations based on junction temperature (Tj)
- Calculates LED valuations, such as lumens / cost
- Estimates simple LED design parameters, such as the number of LEDs required and total power consumption
