Abstract:
A light source is provided that includes at least two semiconductor light-emitting elements that emit light of different color, a light guide, an electronic control unit, and a light sensor. The light emitted by the elements is injected, at least partially, into the light guide and exits laterally from the light guide. The brightness of the elements can be adjusted by the electronic control unit. The light sensor is arranged to receive the light injected by the elements and laterally exiting from the light guide. The electronic control unit accumulates sensor signals from the light sensor over an integration time interval and compares the accumulated signals with a target value or range to determine a difference, changes a brightness of the elements in response to the difference, and changes the integration time interval in response to the difference or to a change in the target value.

Claim (Index 1):
A light source, comprising:\n at least two semiconductor light-emitting elements, the semiconductor light-emitting elements emitting light of different color; a light guide into which the light is, at least partially, injected, the light guide being configured so that the light exits laterally from the light guide, the light guide having a longitudinal extension and an end face; a light sensor arranged to receive the light injected by the semiconductor light-emitting elements into the light guide and laterally exiting therefrom, wherein the light sensor is spaced along the longitudinal extension by a distance of between the light sensor and the end face; and an electronic control unit configured to accumulate sensor signals from the light sensor over an integration time interval of the brightness, determine a difference by comparing the accumulated signals with a target value or target range, change the brightness of the semiconductor light-emitting elements in response to the difference, and change the integration time interval in response to either the difference or a change in the target value or target range.
