Lighting apparatus and image pickup apparatus
First Claim
1. A lighting apparatus comprising:
- a light source;
an optical member which is placed in front of said light source and provided with a reflecting surface to reflect light from said light source forward;
wherein said optic member includes a plurality of pairs of said reflecting surfaces arranged on both sides of the optical axis within a plane including the radial direction of said light source in the direction perpendicular to the optical axis.

Abstract
The present invention discloses a lighting apparatus including a light source, an optical member that is placed in front of the light source and provided with a reflecting surface for reflecting light from the light source or prism sections each made up of a refracting surface which receives the light incident from the light source and a reflecting surface for reflecting the light incident from this refracting surface. Here, in the optical member, there is a plurality of pairs of the reflecting surfaces or prism sections arranged in the direction perpendicular to the optical axis within a plane including the radial direction of the light source centered on the optical axis. The present invention can provide a low-profile lighting apparatus using light from the light source with high efficiency.
