Abstract
An illuminator and a method for fabricating the illuminator are disclosed. The illuminator comprises at least a light source and a discriminator. The light source comprises one or more luminescent layers that substantially convert the energy of a primary electromagnetic radiation to an output radiation. The discriminator comprises one or more layers that substantially transmit the primary electromagnetic radiation to the one or more luminescent layers and reflect at least a portion of the output radiation from the one or more luminescent layers to the viewing hemisphere. A method for applying the illuminator to an object is also disclosed.
Claims29
An illuminator comprising:
- (i) a light source comprising:
- one or more luminescent layers that substantially convert the energy of a primary electromagnetic radiation to an output radiation;
- wherein said one or more luminescent layers comprise one or more luminescent materials;
- and wherein said one or more luminescent materials comprise one or more phosphorescent materials;
- and
- (ii) a discriminator comprising:
- one or more layers that substantially transmit the primary electromagnetic radiation to said one or more luminescent layers and reflect at least a portion of the output radiation from said one or more luminescent layers to the viewing hemisphere.
A method for fabricating an illuminator, the method comprising:
- (i) forming a light source comprising:
- one or more luminescent layers that substantially convert the energy of a primary electromagnetic radiation to an output radiation;
- wherein said one or more luminescent layers comprise one or more luminescent materials;
- and wherein said one or more luminescent materials comprise one or more phosphorescent materials;
- and
- (ii) overlaying a discriminator over a surface of said light source that is remote to the viewing hemisphere, said discriminator comprising:
- one or more layers that substantially transmit the primary electromagnetic radiation to said one or more luminescent layers and reflect at least a portion of the output radiation from said one or more luminescent layers to the viewing hemisphere.
A method for applying an illuminator to an object comprising:
- (i) incorporating said illuminator onto or into at least a portion of the object, said illuminator comprising:
- a light source that comprises one or more luminescent layers that substantially convert the energy of a primary electromagnetic radiation to an output radiation;
- wherein said one or more luminescent layers comprise one or more luminescent materials;
- and wherein said one or more luminescent materials comprise one or more phosphorescent materials;
- and
- a discriminator that comprises one or more layers that substantially transmit the primary electromagnetic radiation to said one or more luminescent layers and reflect at least a portion of the output radiation from said one or more luminescent layers to the viewing hemisphere.
