Abstract:
A self-luminous light source in which ''''fiber optic'''' light transmission media are utilized to transmit light from a radiation-excited light source to one or more light display locations at predetermined distances from the radiation-excited source. In one embodiment the radioactive material within the source is completely surrounded by radiation shielding material such as lead and the ''''fiber optic'''' media follow a curved path within the shield. Other embodiments include apparatus for selectively presenting light of various colors and intensities to the input ends of the ''''fiber optic'''' light transmission media.
Abstract:
A cell for a vacuum ultraviolet plasma light source, the cell having a closed sapphire tube containing at least one noble gas. Such a cell does not have a metal housing, metal-to-metal seals, or any other metal flanges or components, except for the electrodes (in some embodiments). In this manner, the cell is kept to a relatively small size, and exhibits a more uniform heating of the gas and cell than can be readily achieved with a hybridized metal/window cell design. These designs generally result in higher plasma temperatures (a brighter light source), shorter wavelength output, and lower optical noise due to fewer gas convection currents created between the hotter plasma regions and surrounding colder gases. These cells provide a greater amount of output with wavelengths in the vacuum ultraviolet range than do quartz or fused silica cells. These cells also produce continuous spectral emission well into the infrared range, making them a broadband light source.

Abstract:
A flat panel fluorescent lamp and an LCD having the same are provided to prevent a reaction between Hg existing in discharge spaces and a reflective layer by forming a first blocking layer on a lower substrate. An upper substrate(120) is coupled to a lower substrate(110), and forms a plurality of discharge spaces. A first fluorescent layer(130) is formed on an inner surface of the lower substrate. A second fluorescent layer(140) is formed on an inner surface of the upper substrate. A reflective layer(150) is formed between the lower substrate and the first fluorescent layer. A first blocking layer(160) is formed on the lower substrate in order to prevent a reaction between the reflective layer and Hg existing the discharge spaces.
