The secret behind low light decay: Sansi Breakthrough COC (Chip-on-Ceramic) Technology

By mounting LED chips directly onto high-thermal-conductivity ceramic substrates (20-30 W/m·K) using thick-film sintering, we eliminate the insulation layer bottleneck and shorten the heat path by over 60%.

Result? Junction temperature drops 15-20°C lower than conventional aluminum PCBs at the same power, dramatically slowing light decay and boosting reliability.

Better heat dissipation. Longer lifespan. Superior performance.
