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.
Claims20
A cold cathode fluorescent lamp light assembly having at least a first end and at least a second end, said light assembly comprising:
- a miniature elongated cold cathode fluorescent lamp extending between said first end and said second end of said light assembly, and having a first electrode adjacent said first end and a second electrode adjacent said second end, said cold cathode fluorescent lamp further having a narrow tubular lamp wall extending between said two electrodes;
- at least one elongated outer protective panel defining a chamber for retaining and protecting said cold cathode fluorescent lamp, said cold cathode fluorescent lamp being disposed within said chamber;
- a first conductive end cap at said first end of said light assembly and a second conductive end cap at said second end of said light assembly, said first conductive end cap being electrically coupled to said first electrode and said second conductive end cap being electrically coupled to said second electrode, said conductive end caps directly engaging said at least one outer protective panel;
- and
- a first bushing disposed between said cold cathode fluorescent lamp and said at least one outer protective panel adjacent said first end, and a second bushing disposed between said cold cathode fluorescent lamp and said at least one outer protective panel adjacent said second end.
A cold cathode fluorescent lamp light assembly comprising:
- a miniature elongated cold cathode fluorescent lamp having a first electrode, a second electrode, and a narrow tubular lamp wall extending between said two electrodes;
- an elongated chamber for retaining and protecting said cold cathode fluorescent lamp, said chamber having a first end, a second end, and at least one protective panel disposed between said first and second ends, said lamp being disposed within the chamber and extending between said first and second ends of said chamber with its first electrode adjacent said first chamber end and its second electrode adjacent to said second chamber end;
- and
- a first conductive end cap at said first end of the light assembly and a second conductive end cap at said second end of the light assembly, said first conductive end cap being electrically coupled to said first electrode and said second conductive end cap being electrically coupled to said second electrode, said conductive end caps directly engaging said at least one protective panel.
A cold cathode fluorescent lamp light assembly comprising:
- a miniature elongated cold cathode fluorescent lamp having a first electrode, a second electrode, and a narrow tubular lamp wall extending between said electrodes;
- an elongated chamber having first and second ends for retaining and protecting said lamp, said lamp being disposed within said chamber and extending between ends with said first electrode adjacent said first end and said second electrode adjacent said second end;
- a first conductive end cap at said assembly first end and a second conductive end cap at said assembly second end, said first conductive end cap being electrically coupled to said first electrode and the second conductive end cap being electrically coupled to said second electrode;
- a housing including at least one protective panel coupled between said end caps;
- and
- a first bushing disposed between said lamp and said at least one protective panel adjacent said first end, and a second bushing disposed between said lamp and said at least one outer protective panel adjacent the second end, said bushings being completely enclosed within said housing.
