  • Patent number: 8378566
    Abstract: The present invention provides a ceramic-glass composite electrode and a fluorescent lamp having the same. The ceramic-glass composite electrode according to the present invention is a ceramic-glass composite, which is disposed at the ends of a glass tube of the fluorescent lamp. A stopper is disposed at the end of the glass tube for pushing against the ceramic-glass composite electrode and limiting the position of the ceramic-glass composite electrode slipped on the glass tube. Thereby, flowing of adhesives into the glass tube is avoided when the adhesives are used for gluing the glass tube and the ceramic-glass composite electrode, and hence extending the lifetime of the fluorescent lamp.

  • Patent number: 8378565
    Abstract: An electron emitting element includes an electrode substrate, a thin-film electrode, and an electron acceleration layer provided between them. The electron acceleration layer includes a fine particle layer containing insulating fine particles, which is provided on a side of the electrode substrate, and a deposition of conductive fine particles, which is provided on a surface of the fine particle layer. In the electron acceleration layer, a conductive path is formed in advance, and the deposition has a physical recess which is an exit of the conductive path and which serves as an electron emitting section. Electrons are emitted via the electron emitting section. With the arrangement, it is possible to realize an electron emitting element which prevents that an electrode on an electron emission side gradually wears off along with electron emission and which can maintain an electron emission characteristic for a long period.

  • Patent number: 8344608
    Abstract: A long-life hot cathode fluorescent lamp can include a pair of parallel lead wires that can be arranged at each end of a tube. A coiled filament can be connected at its opposite end portions to the lead wires. The coiled filament can have two long pitched regions in which a coil pitch is longer than regions outside of the long pitched regions. Emitter can be located in a region defined between the two long pitched regions. Shape characteristics and intensive current flow obtained by the presence of the long pitched regions can form the origins of discharge near the boundaries between long and short pitched regions. Accordingly, stable discharge can be achieved with the origins of discharge located at ends of the emitter. As a result, the hot cathode fluorescent lamp is allowed to have a long life and stable light emission characteristics.

    Abstract: Organic light emitting devices having a low-index electrode and a substrate with a surface treatment are provided. The combination of a relatively low-index electrode and a surface-treated substrate may eliminate guided modes and increase the light outcoupled by the device. It has been found that the combination surprisingly provides up to 1.5 times more outcoupled light than would be expected based on the performance of similar devices having higher-index electrodes.
