Summary

Nichia's application note discusses the importance of heat sink design for COB (Chip on Board) LEDs, which have high output and dense LED chips, leading to heat concentration. The note evaluates the relationship between heat sink volume and junction temperature (TJ) for various COB models. The results show that larger heat sinks are required to keep TJ within the maximum allowed temperature (TJ Max) for each model. Specifically, the required heat sink volumes are: 10cm3 for NTCxS024B-V1, 40cm3 for NFCxL036B-V1, 350cm3 for NFCxL060B-V1, 400cm3 for NFCxJ108B-V1, and a larger heat sink or additional cooling measures for NFDxJ130B-V1.
