Patent ID: 8229257

Claim:
A light-emitting device for emitting light having a desired color point, comprising: at least one solid-state light source; at least one light-converting element; a light guiding arrangement; and a switch control unit, wherein the solid-state light source is configured to emit primary radiation, the light guiding arrangement is arranged between the solid-state light source and the light-converting element and is provided with an electro-optical switch for receiving an operating voltage and in response thereto for controllably splitting the primary radiation into a first portion and a second portion, the switch control unit is configured to supply the operating voltage to the electro-optical switch for variably adjusting the ratio between the first portion and the second portion of the primary radiation, and the light-converting element includes a first area arranged to receive the first portion of the primary radiation and to at least partially absorb at least the first portion of the primary radiation and to emit secondary radiation therefrom in response to the at least partially absorbed first portion of the primary radiation, and further includes a second area arranged to receive the second portion of the primary radiation.
