Abstract
A rod-shaped light transmission body that has a plurality of prisms and converts light incident from a light source to linear light through the prisms to output the linear light, the prisms including a first prism having a function of totally reflecting the incident light to output the light from the rod-shaped light transmission body, and second and third prisms that are positioned on both sides of the first prism, each of the second and the third prisms having a function of transmitting and deflecting the incident light.
Claims14
A rod-shaped light transmission body including a plurality of prism groups, each group converting light incident from a light source to linear light to output the linear light, wherein
- each prism group comprises a first prism having a function of totally reflecting the incident light to output the light from the rod-shaped light transmission body, and
- a plurality of prisms that are positioned on both sides of the first prism, each prism having a function of transmitting and deflecting the incident light.
A rod-shaped light transmission body that has a prism group converting light incident from a light source to linear light to output the linear light, wherein
- the prism group comprises a first prism having a function of totally reflecting the incident light to output the light from the rod-shaped light transmission body, and second and third prisms that are positioned on both sides of the first prism, each of the second and the third prisms having a function of transmitting and deflecting the incident light.
An illuminating device comprising:
- a light source;
- a rod-shaped light transmission body that has a plurality of prism groups converting light incident from the light source to linear light to output the linear light;
- and
- a planer light transmission body that outputs the linear light incident from the rod-shaped light transmission body from a planer light-outputting face thereof in a planer manner, wherein
- each prism group of the rod-shaped light transmission body comprises a first prism having a function of totally reflecting the incident light to output the light from the rod-shaped light transmission body, and
- a plurality of prisms that are positioned on both sides of the first prism, each prism having a function of transmitting and deflecting the incident light.
An illuminating device comprising:
- a light source;
- a rod-shaped light transmission body that has a plurality of prism groups converting light incident from the light source to linear light to output the linear light;
- and
- a planer light transmission body that outputs the linear light incident from the rod-shaped light transmission body from a planer light-outputting face thereof in a planer manner, wherein
- each prism group of the rod-shaped light transmission body comprises a first prism having a function of totally reflecting the incident light to output the light from the rod-shaped light transmission body, and
- second and third prisms that are positioned on both sides of the first prism, each of the second and the third prisms having a function of transmitting and deflecting the incident light.
A liquid crystal display device comprising:
- an illuminating device including a light source, a rod-shaped light transmission body that has a plurality of prism groups converting light incident from the light source to linear light to output the linear light, and a planer light transmission body that outputs the linear light incident from the rod-shaped light transmission body from a planer light-outputting face thereof in a planer manner, and
- a liquid crystal panel, wherein
- each prism group of the rod-shaped light transmission body comprises a first prism having a function of totally reflecting the incident light to output the light from the rod-shaped light transmission body and a plurality of prisms that are positioned on both sides of the first prism;
- each prism having a function of transmitting and deflecting the incident light.
A liquid crystal display device comprising:
- an illuminating device including a light source, a rod-shaped light transmission body that has a plurality of prism groups converting light incident from the light source to linear light to output the linear light, and a planer light transmission body that outputs the linear light incident from the rod-shaped light transmission body from a planer light-outputting face thereof in a planer manner, and
- a liquid crystal panel, wherein
- each prism group of the rod-shaped light transmission body comprises a first prism having a function of totally reflecting the incident light to output the light from the rod-shaped light transmission body, and second and third prisms that are positioned on both sides of the first prism, each of the second and the third prisms having a function of transmitting and deflecting the incident light.
