Apparatus for regulating the temperature of a light emitting diode

摘要

Apparatus (10) for regulating the temperature of a light emitting diode (LED) (2). The apparatus (10) includes a heat sink (4), an LED mount (6), and an LED (2) mounted on the LED mount (6). The LED mount (6) is configured to change shape in response to a change in temperature. The change in shape alters the position of the LED (2) relative to the heat sink (4), for adjusting heat transfer between the LED (2) and the heat sink (4). The LED mount (6) may include a laminated portion (18,28) such as a bi-metallic strip.
