Filed:

Jan 28, 2003

Appl. No.:

10/352480

Inventors:

Everly Putman - Davenport IA, US
Gary Butler - Atlanta GA, US

International Classification:

C09K011/02
A61K007/04

US Classification:

252/301360, 106/031320, 106/031640, 424/061000, 523/105000, 428/690000

Abstract:

Method of manufacturing a luminescent product exhibiting a daytime color and a glow in the dark color, where the glow in the dark color exhibits long term glow in the dark characteristics after absorbing energy from light sources. At least one resin material and at least one antisettling agent are mixed and combined with a plurality of luminescent crystals capable of glowing in the dark after the absorption of light. This mixture is combined with solvents, colorants, and additives to produce a luminescent material having a daytime color that differs from its glow-in-the-dark color.

Appl. No.:

11/431874

Inventors:

Gary Butler - College Park GA, US

International Classification:

F21V 9/16

US Classification:

362084000, 362360000

Abstract:

The invention provides luminescent phosphor and a method for their manufacture. The invention further provides a method for increasing the resistance to heat and water for the luminescent phosphor by coating the luminescent phosphor. The invention further provides a lamp shade and signage that glows in the dark after activation by incident electromagnetic radiation. Furthermore, a reflector is incorporated into the lamp shade and/or signage to effectively direct the electromagnet radiation emitted from the luminescent phosphor into an open space.

International Classification:

H01J 5/48
H01J 5/50
H01J 63/04

US Classification:

31331801, 31331812, 313485

Abstract:

The invention provides a light bulb that glows in the dark after activation by incident electromagnetic radiation. The element that glows in the dark is an energy storage element and is placed in the center of the light bulb. Furthermore, a reflector is incorporated into the light bulb and/or energy storage element to effectively direct the electromagnet radiation emitted from the luminescent phosphor into an open space.
