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.
