Understand the Integrated Emitting Area
COB integrates several chips on a substrate to form a concentrated emitting area. Its size and shape influence lens and reflector selection.
Look Beyond Power
Confirm package, emitting area, operating voltage, current, color and thermal requirements together. Equal power does not imply equal optical or electrical interfaces.
Work Back from Fixture Requirements
Define the illumination target, installation distance and beam angle, then match driver and source. Test samples under actual thermal conditions to confirm the result.
