摘要:
The invention relates to a light emitter adapted for emitting light with a predefined angular color point distribution, to a method of use for a light emitter in video flash applications, in automotive headlight applications and/or in automotive lamp applications, and to a method, adapted for generating light with a predefined angular color point distribution. The light emitter is adapted for emitting light with a predefined angular color point distribution through an output and comprises a phosphor (2) and a pump source (1), wherein the pump source (1) is adapted for emitting pump light to at least part of the phosphor (2), and the phosphor (2) is adapted for emitting phosphor light by light conversion of absorbed pump light, and wherein a matching element (4) is provided which is arranged at least partly between the phosphor (2) and the output of the light emitter, and which is adapted for adjusting the ratio of the light intensity of the emitted phosphor light emitted by the phosphor (2) towards the output of the light emitter to the light intensity of the transmitted pump light going through the phosphor (2) towards the output of the light emitter. In this way, a versatile light emitter with a predefined angular color point distribution in conjunction with any desired angular light intensity distribution is provided at low costs.
