Document Type and Number:
Japanese Patent JP2019182275
Kind Code:
A
Abstract:
To provide a low-cost optical device which is excellent in light utilization efficiency and can display a complex pattern with a simple configuration.SOLUTION: An optical device 100 for displaying a light condensation mark 400 comprises: a light source 110; and an optical element for condensing light emitted from the light source 110 onto an irradiation surface 301. The deflection surface of the optical element is divided into a plurality of regions. The light emitted through the regions on the deflection surface of the optical element forms, on the irradiation surface 301, partial irradiation images corresponding to the respective regions on the deflection surface. The partial irradiation images are combined, thereby forming at least one light condensation mark 400 on the irradiation surface.SELECTED DRAWING: Figure 2
