Abstract: Cold cathode fluorescent lamps (CCFLs), associated devices and methods of use, and more specifically, exit signs, traffic signals, informational and other signage and lighting devices utilizing CCFL-type devices are provided with novel connectors, mounting brackets, housings, associated electronics and other accessories to provide new and unique lighting devices and methods of using them, all of which offer significant savings in cost, operating expense, power consumption and retrofit convenience.

Abstract: A protected lamp assembly includes a tubular lamp enclosed within a tubular protective housing. The lamp is supported by grommets or bushings of a resilient material that are retained within the housing. An end cap assembly may include the bushing for the lamp and also support the protective housing. Conductors through the end caps communicate with the lamp electrodes. In alternate embodiments the conductors may emerge from one of the end caps or the end caps may include a conductive coating with a connection to the lamp electrodes.

Abstract: A socket unit for fluorescent lamps and especially cold cathode fluorescent lamps has a movable top cover which includes an integral support limb. When in the open position, a lamp is supported by the limb. When in the closed position, the lamp is cammed into engagement with a conductive socket that supplies power to the lamp. As the cover is rotated toward the open configuration, the support limb engages the lamp and pushes it out of engagement with the socket and lifts the lamp to a location where it can easily be removed. In alternative embodiments, the socket can accept a cold cathode fluorescent lamp by engaging a conductive lamp end cap or the socket can accept a conventional, two-pin fluorescent lamp with a pair of conductive clips, one for each pin. Orienting means may be provided to position the lamp for insertion into the socket clips.

Abstract: An optical module for edge lit display signs utilizes energy efficient miniature cold cathode fluorescent lamps. Lampholders that mechanically and electrically couple the lamps include resilient sockets and clamps shaped to engage the outer surface of the resilient sockets. A preferred optical module intended as an illumination source for edge-lit emergency exit signs has two spaced apart cold cathode fluorescent lamps and an optical reflector configured to increase the light coupled to display surfaces of the edge-lit sign.

Abstract: An optical chassis utilizes optical couplers to convert the radial optical distribution of tube-shaped lamps into a more uniform optical distribution on planar illuminated surfaces. An optical chassis designed as an illumination source for emergency exit signs has two lamps and two optical couplers spaced apart on the optical chassis with a voltage converter disposed between the optical couplers. Illumination efficiency and uniformity is improved so that the optical chassis satisfies Underwriter's Laboratory standards for emergency exit sign retrofit kits.
