Luminous intensity distribution system and stereoscopic image display device |
摘要 |
A luminous intensity distribution system includes a first optical element extending in a first direction, and distributes, given that a first direction is taken to be leftward-rightward when viewed frontward-rearward, light having entered a light-incident surface from a right-rear direction and emits the light through a light-emitting surface toward a right-forward direction when viewed from the frontward end, and distributes light having entered the light-incident surface from a left-rear direction and emits the light through the light-emitting surface toward a left-forward direction when viewed from the frontward end; and a second optical element extending in the first direction and that diffuses light having entered the light-incident surface and emits the light through the light-emitting side, with the first optical element and the second optical element being arranged in parallel with each other vertically when viewed frontward-rearward. |

1. A luminous intensity distribution system having a light-incident surface and a light-emitting surface, and in which, given that with respect to the light-emitting surface the system end through which light is emitted is taken to be frontward, the light-incident surface is arranged rearward of the light-emitting surface when viewed from the frontward end, the luminous intensity distribution system comprising:
a first optical element extending in a first direction, and distributing, given that the first direction is taken to be leftward-rightward when viewed frontward-rearward, light having entered the light-incident surface from a right-rear direction and emitting the light through the light-emitting surface toward a right-forward direction when viewed from the frontward end, and distributing light having entered the light-incident surface through a left-rear direction and emitting the light through the light-emitting surface toward a left-forward direction when viewed from the frontward end; and a second optical element extending in the first direction and diffusing light having entered the light-incident surface and emitting the light through the light-emitting surface, wherein the first optical element and the second optical element are arranged in parallel with each other vertically when viewed frontward-rearward. |
