Document Type and Number:
Japanese Patent JP6835922
Kind Code:
B2
Abstract:
To provide an integrated light flux controller capable of detecting positioning with naked eyes.SOLUTION: A light flux controller 10 comprises: a light incident surface 110 for collecting at least half the amount of a light beam on a light source substrate 20 toward the light source substrate 20; a light emission surface 120 for emitting at least 80% or more of the light beam; a bottom surface 140 toward a positioning diagram layer in the light source substrate 20; and a positioning viewing surface 130 having at least one total reflection part 131 arranged on the outer edge of the light emission surface 120 and forming a predetermined included angle with the bottom surface 140, wherein all materials are the same material, when the positioning viewing surface 130 is seen from above with human eyes, all or part of the positioning diagram layer 230 is not visible, and after the included angle between the total reflection part 131 and the bottom surface 140 is changed, the positioning diagram layer 230 can be seen at all the same positions. The positioning situation is detected based on this difference in appearance.SELECTED DRAWING: Figure 1
