SOLID-STATE LIGHT BULB
First Claim
1. A light bulb comprising:
- at least one light emitting element;
a circuit board, said at least one light emitting element mounted on said circuit board;
a heat-conducting frame, said circuit board mounted on said heat-conducting frame;
a connector for attaching the light bulb electrically and mechanically to a receptacle, mounted on an opposite end of said frame from said at least one light emitting element;
a transparent ball, said transparent ball coated with a phosphor, said phosphor comprising a material which is photostimulated by said light-emitting element; and
an interface surface occupying a minor portion of the surface of said ball, said interface surface optically bonded to said at least one light emitting element.

Abstract
An example of this light bulb has a light emitting element (which may be an LED array) mounted on a circuit board. The circuit board is mounted on one end of a heat-conducting frame. An Edison screw or other suitable connector, for attaching the light bulb electrically and mechanically to a receptacle, is mounted on the other end of the frame. A transparent phosphor-coated ball has a flat chord face optically bonded to said array. A light-permeable globular enclosure is mounted on the frame, surrounding the ball and both homogenizing the white light output of the bulb but also concealing the yellowing unlit appearance of the remote phosphor ball centrally located within it.
