System Plus Consulting is proud to publish the reverse costing report of the
Citizen CLL050-1825A1, an UHB LED supplied by Citizen electronics.
Packaged with Chip-On-Board technology (COB), the CLL050-1825A1 has a circular
light-emitting zone at the center of its quadrangular Insulated Metal
Substrate (38mm x 38mm). It integrates 450 LED chips arranged in a circular
shape and covered with resin mixed with red and yellow phosphor.
The LED studied in this report has a luminous Flux of 8,160 lm at 1500 mA and
a correlated color temperature (CCT) of 4000K, which make it suitable for
Stadium and tunnel lights.
This report provides a complete teardown of the LED with:
- Detailed photos
- Material analysis
- Schematic assembly description
- Manufacturing Process Flow
