Title:
OPTICAL ELEMENT AND OPTICAL SYSTEM DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/117283
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an optical element with which it is possible to control not only the light emission direction but also the illuminance, and an optical system device in which the optical element is used. An optical element 10 having at least a part of a rotation body obtained by rotating a reference planar shape 1 for converting light from a prescribed location into light that is parallel with a prescribed direction, or a parallel translation body obtained by performing a parallel translation on the reference planar shape 1, wherein: the reference planar shape 1 comprises an illuminance adjustment part 2 and an emission direction adjustment part 3; the illuminance adjustment part 2 is shaped so as to convert the direction of light entering from the prescribed location 9 so that the illuminance at the emission direction adjustment part 3 is uniform; and the emission direction adjustment part 3 is shaped so as to convert the direction of light to the prescribed direction by refraction.
