Shorten the Design Cycle with Cree Modules


Design Steps

Design Step Needed

Discrete LEDs

Cree Module

Spec lumen output, color temp, CRI, & form factor

Identify suppliers (LEDs, drivers, etc…)

Identify contract designers, if needed

Identify contract manufacturers, if needed

Design LED board

Adjust # LEDs for each color temp (address ANSI bin)

Adjust driver output for each color temp to get required lumens

Design primary optics

Design secondary optics

Design thermal management system

Design final assembly

Submit LED board and driver (if in-house) for regulatory approval

Submit final luminaire for regulatory approval


Engineering Assistance with Every Module

• Lighting application engineers in the module team available for FREE design assistance

– Over 20 years experience in lighting design and manufacturing

– Deep knowledge of manufacturing processes

• Photometric testing in Cree labs
