| 摘要 |
The present invention relates to a lighting device comprising a housing (104), multiple light sources (102) arranged in the housing, a wavelength converting member (108) arranged at a distance from the light sources, and a switchable optical member (111), arranged between the light sources and the wavelength converting member. The wavelength converting member has at least a first wavelength converting material, which converts light of a first wavelength range emitted by the light sources to light of a second wavelength range. The switchable optical member is switchable to adjust a light pattern made by the light sources on the wavelength converting member. Thereby the switchable optical member changes the appearance of the lighting device. |
