A first pair of axially extending terminals on a high voltage insulation plug designed to mount on an end of a gas discharge lamp are separated from each other by a wall that carries a second pair of axially extending terminals mounted on the wall spaced axially from the first pair, the four terminals are adapted for electrical connection to the gas discharge lamp; and a high voltage insulation socket having four axial passageways each containing an axially movable contact spring biased toward the plug, the terminals and passageways so configured that when the plug is rotated on the socket about a common axis with each terminal axially depressing one of the contacts, protrusions on the second pair can be rotated under shoulders in the socket adjacent to the passageways.
Fluorescent Tanning Lamp With Improved Service Life
An electrode shield for a fluorescent tanning lamp comprising an open cup encircling a filament or electrode increasing the service life of the fluorescent tanning lamp. The cup having an open end acts as a shield reducing the sputtering of impurities onto the glass tube and contaminating the phosphor surface. In one embodiment, the cup is electrically and thermally coupled to an electrode support. The life of the fluorescent tanning lamp is greatly increased despite the use of relatively high currents and large number of on and off cycles.
Fluorescent Lamp Providing Uniform Backlight Illumination For Displays

LCD Lighting, Inc. - Orange CT
International Classification:
H01J 1346
US Classification:
315 56, 313491, 313493, 313620
Abstract:
A bent fluorescent lamp for backlighting a display providing uniform illumination. A fluorescent lamp is made from a tubular glass envelope having right angles. The right angles provide improved illumination of a plane surface for backlighting a liquid crystal display. The right angles eliminate dark regions in the illuminated surface. An electrode is positioned sufficiently far from a central portion of the lamp so that any dark spaces in the gas discharge of the fluorescent lamp, such as the Faraday dark space associated with a cathode of a lamp are not formed within the central portion. The central portion of the fluorescent lamp has a uniform brightness or intensity for backlighting a liquid crystal display. A method of forming a right-angled bend in a glass tube is also disclosed.
Cathode With Disintegration Shield In A Gas Discharge Lamp
A cathode shield for a gas discharge lamp having a predetermined size hole proportional to the diameter of a cup and the diameter of the glass envelope of the gas discharge lamp. A conductive cup is placed around an electrode or a filament. The cup is covered with an insulator material having a hole therein. The diameter of the hole in the cover has a proportional relationship to the diameter of the envelope of the lamp and the diameter of the cup. The ratio of the diameter of the envelope and the hole in the cover ranges between 3. 5 and 4. 5. The ratio of the diameter of the cup and the hole in the cover ranges between 2. 0 and 3. It has been determined that these ratios improve current loads without changing discharge characteristics. Additionally, lower temperature operation and starting is facilitated with increased service life. The cathode shield is particularly applicable to germicidal lamps used in water treatment due to the cooler starting and operating temperatures required.
Ozone Generator And Germicidal Device Using An Ultraviolet Lamp
An ultraviolet lamp used for creating ozone. An ultraviolet lamp is enclosed by a container having an inlet at one end and an outlet at the other end. An air flow containing molecular oxygen is created between the container and the ultraviolet lamp. A portion of the wavelength of the ultraviolet lamp is used for generating ozone. Another portion of the wavelength of the ultraviolet lamp is used to kill microorganisms or disinfect a fluid. The ozone generated may be released in the fluid, further purifying and deodorizing the fluid. The present invention combines the germicidal properties of a ultraviolet lamp with the deodorizing properties of ozone in a single device which may be used to purify water or other fluid.

US Classification:
25045511, 250438, 250436, 96224, 422 24, 4221863
Abstract:
A germicidal lamp having a non-uniform contour increasing turbulence. An ultraviolet fluorescent lamp used in a purification system having a helical groove increasing turbulence of the fluid flow. The non-uniform contour may be placed directly on the tubular envelope forming the lamp or may be formed on a separate envelope enclosing a conventional cylindrical tubular germicidal lamp. The germicidal lamp having a non-uniform contour when placed in a fluid flow, such as water or air, creates turbulence, which improves the efficiency of the germicidal action. Smaller, more efficient purification systems requiring less exposure time are obtained.

US Classification:

Abstract:
A bent fluorescent lamp for backlighting a display providing uniform illumination. A fluorescent lamp is made from a tubular glass envelope having right angles formed therein. The right angles provide improved illumination of a plane surface for backlighting a liquid crystal display. The right angles eliminate dark regions in the illuminated surface. A right-angled bend is also formed at the ends of the fluorescent lamp. An electrode is positioned sufficiently far from a central portion of the lamp so that any dark spaces in the gas discharge of the fluorescent lamp, such as the Faraday dark space associated with a cathode of a lamp are not formed within the central portion. As a result, the central portion of the fluorescent lamp has a uniform brightness or intensity providing improved illumination for backlighting a liquid crystal display. The resulting more uniform illumination with less dark regions results in a more legible display and more accurate information being displayed. A method of forming a right-angled bend in a glass tube is also disclosed.
