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.

摘要: A coated luminescent particle 100, a luminescent converter element, a light source, a luminaire and a method of manufacturing coating luminescent particles are provided. The coated luminescent particle 100 comprises a luminescent particle 102, a first coating layer 104 and a second coating layer 106. The luminescent particle 102 comprises luminescent material for absorbing light in a first spectral range and for converting the absorbed light towards light of a second spectral range. The luminescent material is sensitive for water. The first coating layer 104 forms a first barrier for water and comprises a metal oxide or a nitride, phosphide, sulfide based coating. The second coating layer 106 forms a second barrier for water and comprises a silicon based polymer or comprises a continuous layer of one of the materials AlPO4, SiO2, Al2O3, and LaPO4. The first coating layer 104 and the second coating layer 106 are light transmitting. The first coating layer 104 encapsulates the luminescent particle and the second coating layer 106 encapsulates the luminescent particle 102 with the first coating layer 104.
