摘要： An illumination device comprising: an incoherent light source; a non-imaging light collection system disposed to collect light emitted by the light source; an electro-optic modulator that receives light collected by the light collection system and modulates its intensity; and a light delivery system that receives intensity-modulated light output by the electro-optic modulator and illuminates an area with diverging intensity-modulated light. High-powered incoherent, multi-spectral illumination sources, such as lamps or LED arrays, are used. Non-imaging light collection elements, such as fiber optic bundles, total internal reflection lens arrays or compound parabolic light concentrators, are used to reduce the divergence of the light source for efficient transmission of light through an electro-optic modulator.
