Abstract

An illumination system according to the principles of the invention may include a first LED and a carrier material. The carrier material may be comprised of plastic, synthetic material, polymer, latex, rubber or other material. The carrier material may also contain a phosphor, fluorescent material, organic fluorescent material, inorganic fluorescent material, impregnated phosphor, phosphor particles, phosphor material, YAG:Ce phosphor, or other material for converting electromagnetic radiation into illumination or visible light. The illumination system may also have a housing wherein the housing has an open end. The first LED may be arranged to project emitted light through the open end and the carrier material may be cooperatively arranged with the housing such that the emitted light from the first LED is projected through the carrier material.

Claims

1. An illumination system comprising:

at least one LED;

a conversion material comprising at least one of a plastic, a synthetic material, a polymer, latex, rubber, a phosphor, a fluorescent material, an organic fluorescent material, an inorganic fluorescent material, an impregnated phosphor, phosphor particles, a phosphor material, and a YAG;

Ce phosphor; and

a housing having an open end,

wherein;

the at least one LED is arranged to project emitted light through the open end of the housing; and

the conversion material is cooperatively arranged with the housing such that the emitted light from the at least one LED is projected through the material.
