A LIGHT REFLECTOR ARRANGEMENT

摘要

A light reflector arrangement providing a light output having substantially uniform luminous intensity is disclosed. The light reflector arrangement includes at least one light emitting diode (LED) light source. For each light source, the light reflector arrangement includes a first reflector configured to receive light from the light source and reflect said light towards a second reflector such that light reflected from the second reflector has substantially uniform luminance observable from a single direction. For example, the second reflector has light scattering means for removing directionality of light reflected from the second reflector. The light reflector arrangement may further include a lens configured to receive the light reflected from the second reflector. The lens preferably has a light diffusing surface such that light output through the lens has a substantially uniform luminance observable from more than one direction.
