20090085458 | FLUORESCENT MATERIAL AND LIGHT-EMITTING DEVICE - A fluorescent material includes first and second phosphors. The first phosphor is a light-storing phosphor, which is represented by the general formula (M | 04-02-2009 |
20090096370 | FLUORESCENT MATERIAL AND LIGHT-EMITTING DEVICE - A lamp includes a light-emitting body that converts electric energy into light energy and a translucent glass covering the light-emitting body, wherein a phosphor layer is provided on at least inner or outer surface of the translucent glass. The phosphor layer includes a fluorescent material including a first phosphor that at least partially converts energy emitted by an excitation source, which emits ultraviolet having a wavelength of about 365 nm, to a first emission spectrum that is different from the energy, and a second phosphor that at least partially converts the first emission spectrum to a second emission spectrum. Peak wavelengths of the emission spectrum of the first and second phosphors have a relation of complementary colors so that when the light created due to the peak wavelengths of the first and second phosphors are mixed, the resulting light is in the white region. | 04-16-2009 |
