| 摘要 |
The invention relates to the cooling of a light-emitting diode (LED) light source (1). The LED light source (1) is fitted to a circuit card (2); which circuit card is fitted to be fixed via a mechanical fixing interface (3) to a support structure (4). The circuit card comprises at least one conductive layer (5,6) made of thermally conductive material. The aforementioned conductive layer (5,6) is formed to expand from the LED light source towards the edge part (7) of the circuit card, for cooling the LED light source. |
