Abstract: A lampholder for use with cold cathode lamps intended to be wired in a parallel configuration includes an insulating bulb-end receptacle mounted in a conductor housing. The receptacle is divided into a pair of individual bulb-end receiving portions, each of which is provided with a conductive clip which establishes electrical contact with an inserted bulb. At least one of the clips is in two sections which are configured as switch contacts in series with the mains side of a ballast for the lamps. Insertion of a lamp into the clip closes the switch contacts, establishing the mains circuit and allowing high-voltage to be generated and applied to the lamps. The lampholder insures that high-voltage is not produced unless a lamp is in place.

The receptacle is divided into a pair of individual bulb-end receiving portions, each of which is provided with a conductive clip which establishes electrical contact with an inserted bulb. The clips can be configured into a plurality of electrical configurations to allow both single and dual lamp operation to be achieved.

Abstract: A cold cathode fluorescent tube reflector comprises an extruded ABS thermoplastic support subtending an arc of about 317 degrees and dimensioned to snap fit to the tubular body of fluorescent glass tube. The support has bonded thereto a metallized Mylar film which comprises vapor deposited aluminum which forms a specular second surface mirror. The aluminum coating is next to the support and protected from the ambient atmosphere by the clear Mylar film. The reflector is preferably for 7/8 inch diameter tubes and has a film thickness of about 0.8 mils. In one embodiment, the metallized film is attached during extruding of the support. In the alternative, the film is secured to the support during injection molding of the support.

Abstract: An all-weather cold-cathode lighting assembly comprising a series of elongated cold cathode lamp sections electrically interconnected and arrayed in a predetermined geometric configuration having a first end, at least one intermediate bend, and a second end; a series of spaced lampholders including single-socketed endmost feed lampholders supporting the first and second ends of the array and intermediate double-socketed lampholders supporting and electrically connecting adjacent intermediate end portions of the intermediate lamp sections; a weather-proof lens assembly comprising a plurality of elongated transparent or translucent thermoplastic housing sections having walls of generally inverted U-shaped cross section, said housing sections being arrayed congruently with and substantially enclosing said series of lamp sections; said lens housing sections being butted and adhesively joined with clear cement to establish an effectively unitary lens having said predetermined geometric configuration.

Abstract: A molded ceramic housing has two compartments, one for receiving a cold cathode lamp electrode and the other for containing an electrical terminal connected to an electrode contact in the one compartment, the contact engaging the lamp electrode. A ceramic cap encloses the terminal compartment. A ceramic tube is attached to the housing aligned with an aperture in a housing side wall adjacent to the terminal. The tube provides a free air spacer of approximately 1.5 inches in one embodiment. PVC flexible corrugated greenfield tubing is secured in the tube conduit. An electrical power cable extends through the greenfield tubing into the housing and is connected to the terminal. The extended end of the greenfield tubing has a strain relief attached for connection to a rigid metal conduit through which the cable is passed during installation.
