    摘要: An illumination system including a light source, a light guide including an output surface, emissive material positioned to receive light from the output surface of the light guide, and an interference reflector positioned such that the emissive material is between the output surface of the light guide and the interference reflector is disclosed. The light source emits light having a first optical characteristic. The emissive material emits light having a second optical characteristic when illuminated with light having the first optical characteristic. The interference reflector substantially transmits light having the second optical characteristic and substantially reflects light having the first optical characteristic.

    摘要: The present invention provides reflective films and other optical bodies which exhibit sharp bandedges on one or both sides of the main reflection bands. The optical bodies comprise multilayer stacks M1 and M2, each having first order reflections in a desired part of the spectrum and comprising optical repeating units R1 and R2, respectively. At least one of the optical repeating units R1 and R2 varies monotonically in optical thickness along the thickness of the associated multilayer stack.
