Abstract (en)
[origin: EP2355621A2] The circuit (100) has a signal input (110) for receiving a temperature signal, and an electrical power output (120) or a control signal output for controlling an electrical supply device with the power output. The power output provides an electric current for supply of a LED (20) of a light. A low temperature interval and a high temperature interval exist so that the circuit provides lower power when temperature lies in the low temperature interval and the high temperature interval. The low and high temperature intervals are adjoined at threshold temperature. An independent claim is also included for a lighting system comprising a power supply circuit and a temperature sensor.
