Patent ID: 11323670

Abstract:
A light emitting apparatus includes a first light source, a first angle converter, a second angle converter, and a diffuser that is provided on a light incident or exiting side of the first angle converter and diffuses the first light. The first angle converter includes a first light incident section on which the first light is incident, a first light exiting section via which the first light exits out of the first angle converter, and a first reflection section that reflects the first light incident via the first light incident section toward the first light exiting section. The second angle converter includes a second light incident section on which the first light having exited is incident, a second light exiting section via which the first light exits, and a second reflection section that reflects the first light incident via the second light incident section toward the second light exiting section. The area of the first light incident section is greater than the area of the first light exiting section, and the area of the second light incident section is smaller than the area of the second light exiting section.
