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.

Claims

1. A light assembly for receiving a first end and a second end of a light source, said first end having a first electrode, and said second end having a second electrode, said assembly comprising:

a first receiving portion adapted to receive said first end of said light source, and a second receiving portion adapted to receive a second end of said light source;

a durable protective covering for substantially covering said light source;

said first electrode being operatively connectable to a source of electrical energy through said first end member;

said second electrode being operatively connectable to said source of electrical energy through one of said first and second end members.

2. The light assembly of claim 1 wherein said durable protective covering has a continuous surface for encasing said light source.

3. The light assembly of claim 1 wherein said durable protective covering is made of a plastic.

4. The light assembly of claim 1 wherein said durable protective covering is made of a substantially transparent material.

5. The light assembly of claim 1 wherein said durable protective covering is made of a substantially translucent material.

6. The light assembly of claim 1 wherein said durable protective covering extends along a linear axis.

7. The light assembly of claim 1 wherein said light source and said housing extend along a common axis.

8. The light assembly of claim 1 wherein a plurality of lamps are disposed in said housing.

9. The light assembly of claim 1 wherein said light source is a cold-cathode fluorescent lamp.

10. The light assembly of claim 1 wherein said first and second receiving portions along with said protective covering member together protectively enclose said light source for the purpose of protecting said light source from damage while still allowing for electrical connectivity.

11. The light assembly of claim 10 wherein one of said first and second receiving portions includes at least one conductor for connecting said first electrode and said second electrode to said source of electrical energy.

12. The light assembly of claim 10 wherein said first and second receiving portions each include at least one bushing disposed between said lamp and said housing for substantially immobilizing said lamp within said housing.

13. The light assembly of claim 1 wherein said durable protective covering extends non-linearly to enclose said light source which is also non-linear.

14. The light assembly of claim 1 wherein said durable protective covering extends linearly to enclose said light source between said receiving portions.

15. A light assembly as claimed in claim 1 wherein at least one of said first and second receiving portions are detachable from said housing.

16. A light assembly as claimed in claim 1 wherein said durable protective covering comprises a unitary tubular structure.

17. A light assembly as claimed in claim 16 wherein said durable protective covering has a circular cross-sectional shape.

18. A light assembly comprising:

a housing having a first end and a second end;

a cold cathode fluorescent lamp disposed within said housing, said lamp having a first electrode and a second electrode; and

a first end cap for covering said first end of said housing and a second end cap for covering said second end of said housing, said first electrode and said second electrode being operatively connectable to a source of electrical energy through each of said first and second end caps.
