Abstract:
Microwave irradiation treatment is used to enhance the luminescent efficiency by improving surface morphology of the illuminating phosphors. The invention modifies the phosphor particles from the sheet-like shape into the spherical shape and so as to exhibit better crystalline property, thus it may provide for the fabrication of the phosphors with high luminescent efficiency for the optoelectronic devices.
Abstract:
A cold cathode fluorescence flat lamp includes first substrate, second substrate, multiple spacers, multiple first electrodes, blue light fluorescent layer, and discharge gas. The first substrate has a first surface and the second substrate has a second surface. The second surface is opposite to the first surface. The first electrodes are disposed on the first surface of the first substrate. The blue light fluorescent layer is disposed on the second surface of the second substrate. The spacers connected with the edges of the first substrate and the second substrate for forming a chamber between the first substrate and the second substrate. The discharge gas distributes in the chamber. The first electrodes are disposed on the first surface of the first substrate and the blue light fluorescent layer is disposed on the second surface of the second substrate for being away from the plasma formed by the discharge gas.
Abstract:
The present invention provides a flat fluorescent lamp (FFL), including a first substrate, a second substrate, a discharging gas, an electrode set, a dielectric layer and a fluorescent material. The first substrate has at least a first cavity and the second substrate has at least a second cavity. The first substrate and the second substrate are oppositely connected to each other, thus allowing the first cavity together with the second cavity define a discharging space thereby. The discharging gas, the fluorescent material and the electrode set are all disposed in the discharging space. The electrode set is interposed between the first cavity and the second cavity and is adapted for providing a discharging electric field mostly distributed in the discharging space defined therein. In addition, a liquid crystal display (LCD) device using such an FFL is also proposed.
Abstract:
A white LED device is described, including two LED dies capable of emitting a first color light and a second color light, respectively, and a phosphor layer coated on at least one of the two LED dies. The phosphor layer is capable of emitting a third color light when stimulated by the first or second color light, and a light mixing structure is also disposed to mix the first to third color lights into uniform white light without chromatic deviation.
Abstract:
The present invention relates to a package structure for a light emitting diode (LED). The LED package structure of this invention includes a package housing having at least a trench and at least two leads. The package structure includes at least a die or an LED chip disposed on the bottom surface of the trench, while two electrodes of the die are respectively electrically connected to the ends of two leads on the bottom surface of the trench. A transparent plate of glass or crystal materials is mounted and connected to the housing by anodic bonding or glue bonding, to seal the trench, while the other ends of leads are exposed on the surface of the housing without being covered by the transparent plate.
