The ability of a multi-jet single-phase liquid cooling system (jet diameter 400 µm) for thermal management of the high-power LED based luminaire is investigated and successfully demonstrated for a 300 W nominal power module.

With the proposed multi-jet cooling system, the experiments show the possibility of maintaining the module surface temperature well below 70 °C for substrate level heat flux up to ~125 W/cm2. We show that the system can still maintain safe operating temperature, without loss of luminous efficiency for input power up to 130% of the nominal design power.
