Abstract:
A profile of a shadowless reflector, comprising a shade in which an inverted bowl-shaped reflector is mounted; a plain front glass fitted in an opening of the bowl-shaped reflector; a handle having a disk-shaped portion attached to a middle of the plain front glass; a socket installed over the middle of the plain front glass; a bulb placed in said socket opposite said handle; and a cylindrical heat absorbing glass fitted around said bulb, wherein a profile of a reflecting surface of said reflector is defined by at least two coplanar datum curves, each having first and second ends, the first ends of the two datum curves being connected at a connection point,wherein rotation of said at least two datum curves about a centerline of said reflector defines the profile of the reflecting surface of said reflector,wherein one of said datum curves closer to the centerline of the reflector than the other is a first datum curve,wherein the datum curve furthest from the centerline is a second datum curve arranged to cause light rays to evenly illuminate an area of a datum plane, andwherein the first datum curve closer to the centerline is arranged to cause light rays to diverge at the datum plane and illuminate the same area of the datum plane illuminated by light rays reflected by the second datum curve such that light rays reflected by the second end of the first datum curve intersect light rays reflected by the second end of the second datum curve at a same location on an edge of said same area of the datum plane, and such that light rays reflected by the connection point illuminate an opposite edge of said same area of the datum plane.
