    摘要: A gas discharge lamp is disclosed for DC operation which has a double electrode arrangement and a discharge-tight cross connection between electrode spaces. Discharge spaces for the electrodes are provided within a glass envelope. An electrode member in the envelope includes an electrical insulating disk with a central continuous interior bore having two electrodes therein and one or two side bores formed from a periphery of the disk to the interior bore. The side bores accommodate pumping connecting pieces and input lines connected to the electrodes. The interior bore is subdivided by a gas-permeable discharge-tight diaphragm positioned between the two electrodes. Exterior surfaces of the disk are provided with glass solder for joining with face surfaces of the envelope.

    摘要: A backlight for a color LCD includes white light LEDs formed using a blue LED die with a layer of red and green phosphors over it. The attenuation by the LCD layers of the blue light component of the white light is typically greater as the blue wavelength becomes shorter. In order to achieve a uniform blue color component across the surface of an LCD screen and achieve uniform light output from one LCD to another, the blue light leakage of the phosphor layer is tailored to the dominant or peak wavelength of the blue LED die. Therefore, the white points of the various white light LEDs in a backlight should not match when blue LED dies having different dominant or peak wavelengths are used in the backlight. The different leakage amounts through the tailored phosphor layers offset the attenuation vs. wavelength of the LCD layers.
