A reflector film can have a high heat resistance and can maintain a high reflectance (or effectively prevent the decrease in the reflectance) when overlaid with a particular protective film. A lighting apparatus can also be configured for use with such a reflector film. The reflector film can include a silver or silver alloy film deposited on a substrate, and a titanium or titanium alloy film deposited on the silver or silver alloy film to serve as a protective film.
摘要:
A phosphor for use in an electroluminescent panel is produced by firing a material primarily composed of powder of zinc sulfide, preferably with high-frequency induction heating, under a predetermined pressure in an atmosphere of a halogen gas as a coactivator. The phosphor thus produced is of good emission characteristics having minimum particle size and impurity concentration irregularities.

An EL lamp having a higher luminescence efficiency and a process for manufacturing the same are provided. The EL element includes an aluminum foil having at least one specularly polished surface, an anodized oxide film formed on the specularly polished surface of the aluminum foil, a light emitting EL layer formed directly on the film, and a transparent electrode formed on the light emitting EL layer. The process for manufacturing an EL lamp includes the steps of polishing specularly at least one of the surfaces of an aluminum foil, forming an anodized oxide film on the specularly polished surface of the aluminum foil, and forming directly on the aluminum oxide film a light emitting EL layer and a transparent electrode.

摘要:
A phosphor made of phosphor particles coated with inorganic substance lamination, wherein an outermost layer is a transparent layer made of one or more of SiO2, Al2O3 and SiON, having a thickness of about 10 nm to about 500 nm, and formed by fluidized bed CVD, and a transparent inner coating layer is formed inside the outermost layer by a method different from the fluidized bed CVD. The inner coating may be formed by nonaqueous method not using a water content, for example sintering super-fine particles distributed on phosphor particles.

摘要:
A wavelength-converting LED can include a light-emitting section in which an exciting element emits a blue or ultraviolet light. A fluorescent material that has a mean particle diameter D50 ranging from 5 μm to 20 μm and that can convert at least part of the light emitted from the exciting element into light having a wavelength longer than an exciting wavelength, can be incorporated into the LED. A dispersing agent with a mean particle diameter D50 not less than {fraction (1/10)} of the mean particle diameter D50 of the fluorescent material is preferably incorporated in the LED. A binder base material can be arranged to contain the fluorescent material, the dispersing agent and a binder therein. The sum of the weights of the fluorescent material and the dispersing agent is preferably in the range of 20% to 60% by weight of said binder base material to prevent the fluorescent material from precipitating in the binder base material upon curing.
