摘要:
The present invention relates to an LED module (1) for operating based on ambient light sensing. The LED module (1) comprises a control unit (2) for driving at least one LED. At least one LED is an emitting LED (3) for emitting light, and least one LED is a sensing LED (4) for sensing light and outputting a sensing signal (5) according to the sensed light. Based on the sensing signal (5), the control unit (2) is configured to control a light output of the at least one emitting LED (3) obtained from the at least one sensing LED (4). The present invention relates similarly to a method for operating the LED module (1). In particular, the method may control the light output of the at least one emitting LED (3) with a pulse width modulation, PWM, signal, and obtain or evaluate the sensing signal (5) from the at least one sensing LED (4) only in off-periods of the PWM signal.
