Title:
LIGHT IRRADIATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/087723
Kind Code:
A1
Abstract:
The light irradiation device according to the present invention for irradiating line-shaped light extending in a first direction and having a predetermined line width in a second direction onto a predetermined irradiation position on an irradiation surface is provided with a plurality of optical units for emitting line-shaped light in the first direction to the irradiation surface, the optical units having a plurality of light sources aligned in the first direction on a substrate, and a plurality of optical elements for shaping the light from the light sources into parallel light beams. The plurality of optical units comprises N×M (N being an integer of 2 or greater and M being an integer of 1 or greater) optical units for emitting light of N different wavelengths, the N×M optical units being disposed so that the optical paths of the N different wavelengths of light are arranged in a predetermined order in the circumferential direction about an irradiation position as viewed from the first direction, and the range of irradiation in the second direction of each wavelength of light emitted from the N×M optical units is within a predetermined line width.
