Abstract

A lighting system has a heat sink for removing the heat released by LED chips by means of natural convection and thermal radiation. A center opening formed between air and heat sink fins enables the transfer of heat generated by LEDs, electronic driver circuit and phosphor on said heat sink fins to the flowing air inside and removing from the system, and increases the contact surface of heat sink fins with the air that enables to transfer the heat effectively from heat sink fins to flowing air and also with effective radiative heat transfer. The heat sink has a chimney inlet where air enters into said center opening, on which the PCB and said LED package are positioned, and which interconnects LED package and heat sink, which has an optimized structure and base angle, that maximize the heat removal by natural convection and thermal radiation.
