Lighting apparatus
First Claim
1. A lighting apparatus comprising:
- a light emitting section in the shape of a flat plate having a light emitting surface on one side, said light emitting section being made from a light transmitting material;
a light source disposed on an opposite side of said light emitting section with respect to said light emitting surface; and
a light guiding section for guiding light from said light source into said light emitting section through a side surface of said light emitting surface, said light guiding section including a light transmitting section lying in a bent shape from the side surface of said light emitting section, to a position facing said light source, said light transmitting section and said light emitting section being integrally formed from a single piece of said light transmitting material.

Abstract
A lighting apparatus for irradiating a liquid crystal display panel from the back includes a light guiding plate having at least an end which is bent in a direction opposite to the liquid crystal display panel, and a light source disposed on the back surface of the light guiding plate with respect to the liquid crystal display panel. Light from the light source is incident on the bent section of the light guiding plate, reflected by a reflector covering the outside surface of the bent section, and then falls on a section corresponding to a data display space of the liquid crystal display panel. This structure enables an increase in the ratio of the area of a light emitting section to the area of the entire lighting apparatus.

7. A lighting apparatus comprising:
-
a light emitting section in the shape of a flat plate having a light emitting surface on one side, said light emitting section being made from a light transmitting material; a light source disposed on an opposite side of said light emitting section with respect to said light emitting surface; and a light guiding section for guiding light from said light source into said light emitting section through a side surface of said light emitting surface, wherein said light guiding section further includes a light reflecting section for covering an outside surface of said light transmitting section except at least a portion facing said light source, wherein said light source is a tube-like light source which is disposed so that an axis of said light source is parallel to a longitudinal direction of the side surface of said light emitting section, and said light transmitting section is formed so that a profile perpendicular to the axis of said light source is substantially a trapezoid having the side surface of said light emitting section as a part of a base of the trapezoid. - View Dependent Claims (8, 9)
