    摘要： A lighting unit is provided which comprises: a plurality of linear light sources arranged in parallel; light-guiding plates arranged along said light sources; light diffusion means arranged at the top of said light sources and light-guiding plates; and reflection means arranged at the bottom of the light sources; wherein said lighting unit is characterized in that the surface of each light-guiding plate is flat, in that the reverse side of the light-guiding plate includes an inclined face of a curvilinear shape that thins down as the inclined face is more distanced from the light source, and in that when a position relatively near the light source and a position relatively far from the light source, on the reverse side of the light-guiding plate, are inclined by &thgr;n1 and &thgr;f1, respectively, the relationship of &thgr;n1 ≧&thgr;f1 is satisfied and the angle-of-inclination of the thinnest portion on the reverse side of the light-guiding plate is 0 degrees. With this arrangement, supply of a thin lighting unit that is high in luminance and in the in-plane uniformity of luminance can be obtained.

    摘要： An illumination apparatus provides an improved light utilization efficiency and improved collimation. The illumination apparatus has a light guide, a collimating unit provided at least on one side of the light guide for collimating rays incident on the light guide, and a light source disposed in the vicinity of the collimating unit and surrounded by a reflector. Preferably, in order for the light guide to be able to emit collimated light uniformly from its emission surface, the light guide has inclined reflecting irregularities or stepwise reflecting plates which are provided directly or via an air gap on a back surface opposite to the emission surface thereof, wherein the inclined reflecting plates are specular-finished at least on the inclined portions.
