Title:
LIGHTING DEVICE AND TRAVELING BODY USING SAME
Document Type and Number:
WIPO Patent Application WO/2017/094214
Kind Code:
A1
Abstract:
The objective of the invention is to provide a lighting device capable of forming a line beam whereof the length in the irradiation direction is sufficiently long. The lighting device uses: a light source (100) comprising a plurality of light emitters aligned into a straight line; and a lens (101) comprising an exit surface of a constant curvature corrected by an odd-order function. The distance between an irradiated surface (102) and a light source extremity on the side of the irradiated surface (102) is longer than the distance between the irradiated surface (102) and the lens center (123). In this state, by imaging the shape of the light source (100) onto the irradiated surface (102), the line beam (107) can be formed whereof the length in the irradiation direction is sufficiently long.
