Title:
LIGHTING APPARATUS
Document Type and Number:
Japanese Patent JP2017010889
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a lighting apparatus provided with a light guide plate having dots provided on a front surface and a rear surface, capable of improving appearance, capable of light distribution control by the light guide plate, and capable of suppressing moire.SOLUTION: A lighting apparatus 1 comprises: a light source unit 2; and a light guide plate 3 guiding light from the light source unit 2 and emitting the light to outside. The light guide plate 3 has an incidence surface 31 on which the light from the light source unit 2 is incident, and emission surfaces 32 and 33 from which the light incident on the incidence surface 31 is emitted. The emission surfaces 32 and 33 include dots 6 and 7 formed by micro-prism processing, respectively. The dots 6 and 7 positionally deviate from each other in a rotation symmetrical fashion. With this configuration, interference of the dots 6 and 7 is reduced without giving light diffusibility to the light guide plate 3, so that appearance can be improved by configuring the light guide plate 3 to be transparent, the light guide plate 3 can exert a light distribution control, and generation of moire can be suppressed.SELECTED DRAWING: Figure 1
