摘要:
An electric discharge lamp includes a light transmissive inner jacket (12) that defines a sealed inner chamber (14), a first material (20) in the inner chamber (14) that emits light when activated, and a light transmissive outer jacket (16) around the inner jacket (12). The outer jacket (16) defines a sealed outer chamber (18) between the inner (12) and outer (16) jackets that contains a second fill material (22). The second fill material (22), when activated by heat from the inner chamber (14) when the lamp is operating, converts ultraviolet (UV) and deep blue light emitted from the inner chamber (14) to visible light, thereby increasing an amount of visible light transmitted through the outer jacket (16) compared to an amount of visible light transmitted through the inner jacket (12).

摘要:
Ultraviolet and vacuum ultraviolet radiators (100) for use in the manufacture of semiconductors are provided which have improved lifetimes, improved distribution of radiation generation, improved distribution of emitted radiation, increased efficiency of radiation emission, and improved means for cooling. The radiators (100) have novel electrodes (106), novel electrode configurations, novel means for distributing plasmas between electrodes, and have novel cooling means. These features enable the miniaturization of the radiators permitting high intensity and uniform radiation exposure of planar surfaces. The radiators are used in the pre-treatment of semiconductor surfaces, the deposition of semiconductor thin films, and the post-deposition processing of semiconductor thin films.

摘要:
A light source device (100) includes a discharge tube (20), a discharge medium sealed inside the discharge tube (20), and inner and outer electrodes (21) and (22) for exciting the discharge medium. The outer electrodes (22) include a first outer electrode (23) and a second outer electrode (24) that are connected electrically with each other. The first outer electrode (23) is in contact with an outer surface of the discharge tube (20) at a plurality of first contact portions that are located at different distances from the inner electrode (21) and are provided discontinuously. The second outer electrode (24) is in contact with the outer surface of the discharge tube (20) at second contact portions. The second contact portions are arranged closer to the inner electrode (21) than the first contact portions at a surface density greater than that of the first contact portions. Thus, it is possible to provide a light source device with decreased fluctuations in the brightness distribution and with higher brightness, and a liquid crystal display device in which the light source device is employed.
摘要:
Disclosed are a gas discharge tube used for the backlight of a liquid crystal display (LCD) or the like and a drive method for the same. A flat type gas discharge tube comprises two plane glasses, a barrier and at least one electrode group comprised of a plurality of parallel electrodes. Voltages are applied to each electrode group in one discharge period in such a way that discharges of a rare gas dispersed spatially and along the time are allowed to occur. Even when a single gas discharge tube is used for the backlight of an LCD having a large display area, therefore, it does not suffer luminance unevenness and the locations of discharge can be dispersed spatially and along the time, thus ensuring a high emission efficiency. As the backlight does not require a light guide plate or a diffusion sheet, its manufacturing cost becomes lower.
