Patent ID: 8672523

Claim:
A light emitter adapted for emitting light with a predefined angular color point distribution through an output, comprising: a phosphor layer, a pump source for emitting pump light to at least part of the phosphor layer, the phosphor layer, being configured for emitting phosphor light by light conversion of a first portion of the pump light, wherein said first portion of the pump light is absorbed by the phosphor layer; and a matching element arranged at least partly between the phosphor layer and the output of the light emitter, and configured for adjusting the ratio of the light intensity of the emitted phosphor light emitted by the phosphor layer towards the output of the light emitter to the light intensity of the transmitted pump light, wherein said second portion of the pump light is unconverted and is transmitted through the phosphor layer towards the output of the light emitter, wherein the matching element is further configured to modify an angular light intensity distribution of said second portion of the pump light by biasing the second portion of the pump light toward at least one direction over at least on other direction at said output such that an angular light intensity distribution of said emitted phosphor light is primarily unchanged by the matching element.
