NSCWJ216A Light Emitting Diode Heat dissipation performance according to the adhesion strength of COB and housing Application Note

PublishTime：2021-11-26

●Overview
■COBs have been recently introduced in LED lighting applications and expanded into the market.
■It is very necessary to consider heat dissipation to design the lighting fixture installing COBs.
■A single COB can achieve a high output power. Moreover, the design of COBs allows the heat to be concentrated in a narrow space, because the multiple dice are closely mounted. Thus, it is necessary to verify the heat dissipation when designing the lighting fixture, not to degrade the performance by heat (e.g. decrease in the luminous flux according to the temperatures) or not to deteriorate the reliability performance.
■This document shows the evaluation results of the heat dissipation performance according to the adhesion strength of COBs and the housing (heat sink).
