Title:
LIGHT SHAPING DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/087918
Kind Code:
A1
Abstract:
The present invention shapes light emitted from a linear light source while constraining structural size increase. This light shaping device is provided with: a linear light source (20) having light emission points (101); a reflecting mirror (32) having an orthogonal parabolic surface; and an optical element (40) disposed at the light condensing point (200) where light (100) emitted from the linear light source converges, wherein the light emitted from the linear light source is reflected by the reflecting mirror surrounding the linear light source, and further converges at the light condensing point; the reflecting mirror has a rotational axis that is in the longitudinal direction of the linear light source; the light emission points of the linear light source are situated on the rotational axis of the reflecting mirror; and in the optical element, an incident end face (41), where the light emitted from the linear light source enters, is situated at the light condensing point.
