Patent ID: 7108417

Claim:
A lighting apparatus comprising a first light source, a second light source spaced from the first light source, and a linear light conductor disposed between the first light source and the second light source, for causing light entering from the first light source and the second light source to exit linearly from an exit side, on the reflection side of the linear light conductor, which is opposed to the exit side, a plurality of first light reflection parts in the form of first V-shaped grooves, for reflecting light entering from the first light source and a plurality of second light reflection parts in the form of second V-shaped grooves, for reflecting light entering from the second light source being formed, and an intersection angle of the planes of the first V-shaped groove and an intersection angle of the planes of the second V-shaped grooves being substantially equal to each other, a plurality of the first reflection planes which are respective ones of the planes of the first V-shaped grooves, which are on the side of the first light source, being tilted at respective angles at which the light entering from the first light source exits in the direction substantially perpendicular to the longitudinal direction of the linear light conductor, and an intersection angle of the planes of the first V-shaped grooves being substantially equal to each other, a plurality of the second reflection planes which are respective ones of planes of the second V-shaped grooves, which are on the side of the second light source, being tilted at respective angles at which the light entering from the second light source exits in the direction substantially perpendicular to the longitudinal direction of the linear light conductor, an intersection angle of the planes of the second V-shaped grooves being substantially equal to each other, and the intersection angle of the planes of the first V-shaped grooves and the intersection angle of the planes of the second V-shaped grooves being substantially equal to each other, and said plurality of first light reflection parts being formed in at least a region near the end of the linear light conductor, opposite to the end thereof near which the first light source is disposed, and said plurality of second reflection parts being formed in at least a region near the end of the linear light conductor opposite to the end thereof near which the second light source is disposed.
