Abstract
Abstract A solid state lamp, comprising an infrared-emitting diode mounted to usefully emit infrared radiation from a surface thereof, and a phosphor material placed at or around the edge of the diode to convert edge-emitted infrared energy into visible light, whereby visible light accompanies the emitted infrared thereby visually indicating whether the lamp is on or off and also aiding in focusing or aiming the infrared.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
88 words
A visible-infrared solid state lamp comprising an infraredemitting element arranged to usefully emit infrared radiation from a surface thereof, and also emitting infrared radiation from the edge thereof, a phosphor material positioned adjacent to at least a portion of said edge of the element and having the characteristic of converting said edge-emitted infrared into visible light, and a lens positioned over said infrared-emitting surface and phosphor material, said surface of the element being essentially free of phosphor material so as to radiate infrared radiation unimpededly toward said lens.
Claim 2
Dependent Claim
88 words
A visible-infrared solid state lamp comprising an infraredemitting element arranged to usefully emit infrared radiation from a surface thereof, and also emitting infrared radiation from the edge thereof, a phosphor material positioned adjacent to at least a portion of said edge of the element and having the characteristic of converting said edge-emitted infrared into visible light, and a lens positioned over said infrared-emitting surface and phosphor material, said surface of the element being essentially free of phosphor material so as to radiate infrared radiation unimpededly toward said lens.
Claim 3
Dependent Claim
74 words
A lamp as claimed in claim 1, including a support member having a substantially flat surface of greater area than that of said element, and means mounting said element on said flat surface of the support member in a position so that the element lies within the confines of said flat surface, said phosphor material being positioned in contact with at least a portion of said flat surface and said edge of the element.
Claim 4
Dependent Claim
36 words
A lamp as claimed in claim 2, including a cover member attached to said support member, said lens being carried by said cover member and positioned over and spaced from said infrared-emitting element and phosphor material.
Claim 5
Dependent Claim
79 words
A lamp as claimed in claim 1, including a support member having a substantially flat surface provided with a recess therein, means mounting said element in said recess with the infrared-emitting surface thereof facing outwardly and being substantially parallel to said surface of the support member, the relative sizes of said recess and said element being such that a portion of the recess surrounds the element, said phosphor material being positioned in and filling said portion of the recess.
Claim 6
Dependent Claim
27 words
A lamp as claimed in claim 4, in which said surface of the element lies in substantially the same plane as said surface of the support member.
