Optothermal LED lighting for high lumen extraction and extended lifetime

A lighting system has a dielectric cooling fluid which directly contacts with an LED chip; contacts with the heat sink base by moving towards the heat sink base, i.e. upwards, with the decreasing density as a result of the increased temperature due to the high temperature formed in the LED chip; at...

Beschreibung
Zusammenfassung:	A lighting system has a dielectric cooling fluid which directly contacts with an LED chip; contacts with the heat sink base by moving towards the heat sink base, i.e. upwards, with the decreasing density as a result of the increased temperature due to the high temperature formed in the LED chip; at the same time the temperature thereof decreasing upon contacting with the heat sink base; moves towards the LED chip, and reduces the temperature of the LED chip by contacting the LED chip upon said movement; and movement channels through which the cooling fluid in gaseous or liquid phase passes during the movement of said cooling fluid.
