Abstract
Abstract A lens cap is positioned over a light-emitting diode, and a somewhat conical-shaped plastic light director extends between and in intimate contact with the lens cap and the diode, the smaller end of the conical light director being at the diode. A method of manufacture is disclosed in which a viscous plastic monomer is placed in the lens cap and/or on the diode and allowed to deform by gravity to form the conical light director.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
81 words
A solid state lamp construction comprising a light-emitting diode, mounting means for holding said diode, and a lens positioned over said diode and its mounting means with a surface of the lens spaced from and facing a surface of the diode, wherein the improvement comprises a conical shaped light director extending between and in intimate molded contact with said surface of the diode and said surface of the lens, the smaller end of said conical light director being at said diode.
Claim 2
Dependent Claim
81 words
A solid state lamp construction comprising a light-emitting diode, mounting means for holding said diode, and a lens positioned over said diode and its mounting means with a surface of the lens spaced from and facing a surface of the diode, wherein the improvement comprises a conical shaped light director extending between and in intimate molded contact with said surface of the diode and said surface of the lens, the smaller end of said conical light director being at said diode.
Claim 3
Dependent Claim
26 words
A lamp construction as claimed in claim 1, in which said surface of the lens is shaped to have a convex curvature facing toward said diode.
Claim 4
Dependent Claim
19 words
A lamp construction as claimed in claim 2, in which said lens is shaped to provide a biconvex lens.
Claim 5
Dependent Claim
85 words
A lamp construction as claimed in claim 2, including a lens cap having a symmetrically circular cross-sectional shape, said lens being at an end of said lens cap, said lamp construction including a circular header, means for mounting said diode on said circular header, said lens cap being positioned with the open inner rim end thereof surrounding at least a portion of said circular header, and means for attaching said lens cap and header together at said open inner rim end of the lens cap.
Claim 6
Dependent Claim
105 words
A lamp construction as claimed in claim 4, in which said means mounting the diode on the header comprises a pedestal member attached at the bottom thereof to said header, said diode being attached to the top surface of said pedestal member, said top surface of the pedestal member being larger than the diode, the diode being positioned within the confines of said top surface of the pedestal member, and said smaller end of the conical light director being in intimate molded contact with said surface of the diode and also with the portion of said top surface of the pedestal member around said diode.
Claim 7
Dependent Claim
23 words
A lamp construction as claimed in claim 1, in which said conical shaped light director is of a material which is permanently resilient.
Claim 8
Dependent Claim
22 words
A lamp construction as claimed in claim 6, in which said material of the light director is a cured viscous plastic monomer.
Claim 9
Dependent Claim
17 words
A lamp construction as claimed in claim 7, in which said viscous plastic monomer is silicone rubber.
Claim 10
Dependent Claim
29 words
A lamp construction as claimed in claim 1, in which the cross-sectional area of said conical shaped light director increases approximately exponentially in the direction away from said diode.
