High output radial dispersing lamp using a solid state light source
First Claim
1. A lamp, comprising:
- a light source;
a disperser that scatters, focuses, or directs light passing through it; and
a separator having two ends, said light source disposed at one of said two ends and said disperser disposed at the other of said two ends, at least some of the light from said light source directed along said separator and through said disperser.

Abstract
The invention provides a new solid state lamp emitting a light useful for room illumination and other applications. It comprises a solid state Light Source which transmits light through a Separator to a Disperser that disperses the light in a desired pattern and/or changes its color. In one embodiment, the Light Source is a blue emitting LED operating with current high enough for room illumination, the Separator is a light pipe or fiber optic device, and the Disperser disperses the light radially and converts some of the blue light to yellow to produce a white light mixture. The Separator spaces the Light Source a sufficient distance from the Disperser such that heat from the Light Source will not transfer to the Disperser when the Light Source is carrying elevated currents necessary for room illumination.

39. A lamp, comprising:
-
a light source comprising at least one light emitting diode that emits an output light flux sufficient for room illumination;
a disperser that disperses light passing through it;
a separator having two ends, said light source mounted at one of said two ends and said disperser mounted at the other of said two ends, said light source and disperser spaced apart by said separator a sufficient distance to prevent substantial heat transfer from said light source to said disperser, at least some of the light from said light source directed along said separator and through said disperser;
a hollow lamp enclosure that is a least partially transparent and containing materials to change the wavelength of at least some of the light which passes through it, said enclosure surrounding said light source, separator and disperser such that light dispersed by said disperser passes through said enclosure. - View Dependent Claims (40, 41, 42, 43)

44. A multiple element lamp, comprising:
-
at least two individual lamps whose light mixes to produce the light from said multiple element lamp, each said individual lamp comprising;
a light source;
a disperser that scatters, focuses, or directs light passing through it; and
an elongated separator having two ends, said light source disposed at one of said two ends and said disperser disposed at the other of said two ends, at least some of the light from said light source directed along said separator and through said disperser. - View Dependent Claims (45, 46, 47)
