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 18):
The light source as in  claim 17 , wherein the light mixer comprises a second light guide obliquely beveled with a bevel face and having a light entry area which is defined by a non-beveled end face of the second light guide, and a light exit area which is defined by a surface area of a wall at that end of the second light guide at which the bevel face is arranged, and a second optical element is provided which is defined by the light guide or by an optical element interposed between the light guide and the light mixer, wherein the second optical element has a light entry aperture arranged on the light exit area of the light mixer or facing the light exit area of the first optical element, wherein the light entry area of the second light guide has a width x measured in the direction along the intersection of the light entry area with the plane of light deflection at the bevel face, and the light entry aperture of the second optical element has a height z measured in the direction along the intersection of the light exit area of the second light guide with the plane of light deflection at the bevel face, which meet the following relationship:\n x/z \u22641.5\u00b7[tan(90\u00b0\u2212\u03b1/2)\u2212tan(90\u00b0\u2212(2\u00b7[\u03b1/2+90\u00b0]\u2212[180\u00b0\u2212arcsin(1 /n )]))] \u22121 , wherein \u03b1 denotes the deflection angle of the light at the bevel face, and n denotes the refractive index of the material of the second light guide.
