Color point variable light emitting apparatus
Abstract:
A color point variable light emitting apparatus is provided. The color point variable apparatus comprises a member comprising a wavelength converting element and a non-wavelength converting element, the wavelength converting element is arranged to convert light of a first wavelength into light of a second wavelength and emit the light of the second wavelength, and the non-wavelength converting element is arranged to redirect light of the first wavelength, a light source having a controllable optical element, the light source is arranged to, with light of a first wavelength, illuminate both a portion of the wavelength converting element and a portion of the non-wavelength converting element, and a controller arranged to control the controllable optical element such that a ratio of the portion of the wavelength converting element and the portion of the non-wavelength converting element illuminated by the light source is changed. A method for varying color point of light is further provided.
