This page covers CoB LED basics, including an application note and a list of CoB LED manufacturers/vendors.

CoB LED Application Note

Recently, Lumileds introduced CoB (Chip On Board) LEDs. These LEDs offer an average of 10% higher efficacy and 10% higher flux, all while maintaining the same footprint as 1st generation LEDs at a lower voltage. CoB LEDs are available in various lumen packages.

LEDs with less than 1000 lumens are suitable for PAR and MR16 lamps, while LEDs with up to 7600 lumens can replace 100W CDM lamps.

RCOB LED Driver

RECOM Electronic has developed an RCOB LED driver to meet the specific requirements of CoB LEDs. They offer about 11 different models with output voltages ranging from 25V DC to 44V DC and constant output currents from 350 to 1050 mA. This wide voltage and current range makes the driver suitable for a broad spectrum of applications.
