LED LAMP SYSTEM

摘要

The invention relates to a LED lamp system comprising: a heat sink (30), a LED assembly (20) thermally coupled to the heat sink (30), an air inlet (Al) and an air outlet (AO), the air inlet (Al) and the air outlet (AO) being positioned for obtaining an air flow (115) along the heat sink (30), wherein the LED assembly (20) has a light-emitting side in operational use, wherein the air flow (115) is caused by heat generated by the LED assembly (20), the air inlet (Al) and the air outlet (AO) being located substantially in plane with the LED assembly (20) or on a back side of the LED assembly (20), wherein the back side is defined as being opposite to the light-emitting side. The LED lamp system in accordance with the invention is a lighting system which makes use of passive cooling only. The cooling mechanism relies on the airflow that runs along the heat sink which air flow is sustained by the heat generated by the heat sink itself. No additional power is required.
