Light emission source and light emission method using light emission source
First Claim
1. A light emission source comprising:
- a reflector, a first light reflecting surface disposed on the reflector, a light guide disposed on the side of the reflector with the first light reflection surface, and a light emitter for emitting light towards the light guide, wherein the light guide comprises;
a second light reflection surface disposed facing the first light reflection surface for reflecting some light and transmitting remaining light, and a light emission surface disposed on an opposite side of the second light reflection surface on the light guide for transmitting light emitted from the light emitter, light reflected by the first light reflection surface, and light reflected by the second light reflection surface.

Abstract
A light emission source includes a reflector, a first light reflecting surface disposed on the reflector, a light guide disposed on the side of the reflector with the first light reflection surface, and a light emitter for emitting light towards the light guide. The light guide includes a second light reflection surface disposed facing the first light reflection surface for reflecting some light and transmitting remaining light, and a light emission surface disposed on an opposite side of the second light reflection surface on the light guide for transmitting light emitted from the light emitter, light reflected by the first light reflection surface, and light reflected by the second light reflection surface. A light emission source includes a light guide. The light guide includes a light emitter, a first light reflection surface for reflecting light emitted from the light emitter, and a light emission surface for transmitting light emitted from the light emitter, and light reflected by the first light reflection surface. The first light reflection surface includes two types of reflection surfaces. The two types of reflection surfaces include a partial reflection surface for reflecting some light and transmitting remaining light, and a high reflectance reflection surface for reflecting nearly all light. A light emission method uses such a light emission source. A light emission source array, a backlight, and a liquid crystal display apparatus includes a plurality of such light emission sources.

16. A light emission method using a light emission source, the light emission source comprising:
-
a reflector, a light guide disposed on a reflective side of the reflector, and a light emitter for emitting light towards the light guide, wherein a surface of the light guide facing the reflector reflects some of the light emitted by the light emitter, and transmits the remaining light, a light reflection surface on the reflector reflects the light transmitted through the light guide, and the light emitted by the light emitter, the light reflected by the surface of the light guide facing the reflector, and the light reflected by the light reflection surface on the reflector are emitted towards the outside of the light emission source.
