Document Type and Number:
Japanese Patent JP6537899
Kind Code:
B2
Abstract:
A light emitting apparatus for a vehicle includes a light source, a diffuser and a beam guider. The light source emits light having a beam pattern with a first imaginary line starting from a center of the beam pattern and extending to a perimeter of the beam pattern and a second imaginary line starting from the center of the beam pattern and extending to the perimeter of the beam pattern at a preset angle relative to the first imaginary line. The first and second imaginary lines have lengths different from each other. The diffuser receives the light of the light source and diffuses the received light to reduce the difference between the lengths of the first and second imaginary lines. The beam guider guides the diffused light along a path to produce an outlet light within a preset range.
