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.
Claims74
An illumination apparatus, comprising:
- at least one first light emitting diode (LED) adapted to generate first radiation having a first spectrum;
- at least one second LED adapted to generate second radiation having a second spectrum;
- a housing coupled to the at least one first LED and the at least one second LED;
- and
- at least one conversion material associated with only a portion of the housing and arranged with respect to the at least one first LED and the at least one second LED such that only one of the first radiation and the second radiation, when generated, substantially interacts with the at least one conversion material, the at least one conversion material configured to change at least one frequency component of a corresponding one of the first spectrum and the second spectrum so as to provide at least one converted spectrum.
2 more elements
An illumination method, comprising acts of:
- A) generating first radiation having a first spectrum from at least one first LED;
- B) generating second radiation having a second spectrum from at least one second LED;
- and
- C) irradiating at least one conversion material associated with only a portion of a housing with at least one of the first radiation and the second radiation such that only one of the first radiation and the second radiation substantially interacts with the at least one conversion material, the at least one conversion material configured to alter a corresponding one of the first spectrum and the second spectrum so as to provide at least one converted spectrum.
