Abstract

A fluorescent lamp tube catcher formed of bent wire can be detachably engaged with a light fixture, with the central portion of the lamp tube catcher positioned below fluorescent tubes in the light fixture during use. In the event that a fluorescent lamp tube inadvertently becomes loose in the light fixture, the fluorescent lamp tube catcher can stop the loose fluorescent lamp tube from falling. The fluorescent lamp tube catcher can be loosely retained on the light fixture, for example while replacing a fluorescent lamp tube that has failed.

Claims

1. A fluorescent light fixture with lamp tube catcher, comprising:

a first frame portion supporting at least one first lamp socket;

a second frame portion supporting at least one second lamp socket;

at least one reflector defining a longitudinal axis and extending between the first frame portion and the second frame portion, and configured to reflect light emitted from a fluorescent lamp tube extending between the first lamp socket and the second lamp socket;

a first edge extending substantially along the length of the reflector on a first side of the light fixture and a second edge extending substantially along the length of the reflector on a second side of the light fixture;

an elongated wire member having a first end defining a first hook and a second end defining a second hook, the first hook slidably coupled to the reflector along the first edge and the second hook slidably coupled to the reflector along the second edge, so that the elongated wire member may be disposed at any one of a plurality of locations along the length of the reflector.

2. The fixture of claim 1 wherein the elongated wire member is formed by bending a unitary piece of wire.

3. The fixture of claim 2 wherein the first and second hooks comprise a hook angle of about 20 degrees.

4. The fixture of claim 1 wherein the elongated wire member defines a substantially straight line between the first end and the second end.

5. A fluorescent light fixture with lamp tube catcher, comprising:

a first frame portion supporting at least one first lamp socket, the first frame portion having a first side with a first threaded member and a second side with a second threaded member;

a second frame portion supporting at least one second lamp socket;

at least one reflector defining a longitudinal axis and extending between the first frame portion and the second frame portion, and configured to reflect light emitted from a fluorescent lamp tube extending between the first lamp socket and the second lamp socket;

an elongated wire member having a first end defining a first loop removably supported by the first threaded member and a second end defining a second loop removably supported by the second threaded member, the elongated wire member including a central portion extending between the first end and the second end and configured to support the fluorescent lamp tube in the event that the fluorescent lamp tube disengages from one of the lamp sockets.

6. The fixture of claim 5 wherein the elongated wire member is formed by bending a unitary piece of wire.

7. The fixture of claim 5 wherein the second frame portion comprises a first side with a first threaded member and a second side with a second threaded member.

8. The fixture of claim 7 further comprising a second elongated wire member having a first end defining a first loop removably supported by the first threaded member on the second frame portion and a second end defining a second loop removably supported by the second threaded member on the second frame portion, the second elongated wire member including a central portion extending between the first end and the second end and configured to support the fluorescent lamp tube in the event that the fluorescent lamp tube disengages from the second lamp socket.

9. The fixture of claim 8 wherein the central portion of each of the elongated wire members includes first and second legs extending substantially parallel to the longitudinal axis and a mid portion extending between the first and second legs and substantially perpendicular to the longitudinal axis.

10. A fluorescent light fixture with lamp tube catcher, comprising:

a first frame portion having a first side and a second side, and supporting at least one first lamp socket;

a second frame portion having a first side and a second side and supporting at least one second lamp socket;

at least one reflector defining a longitudinal axis and extending between the first frame portion and the second frame portion, and configured to reflect light emitted from a fluorescent lamp tube extending between the first lamp socket and the second lamp socket;

an edge extending substantially along the length of at least one side of the reflector;

a first elongated wire member extending substantially parallel to the longitudinal axis and having a first end coupled to the first end of the first frame portion and a second end coupled to the second end of the second frame portion; and

a second elongated wire member having a first end defining a loop disposed about the first elongated wire member for slidable engagement along at least a portion of the length of the first elongated wire member, and a second end defining a hook slidably coupled to the reflector along the edge, so that the second elongated wire member may be disposed at any one of a plurality of locations between the first frame portion and the second frame portion.

11. The fixture of claim 10 wherein the first frame portion includes a first threaded member and the second frame portion includes a second threaded member.

12. The fixture of claim 11 wherein the first end of the first elongated wire member defines a first loop supported by the first threaded member and the second end of the first elongated wire member defines a second loop supported by the second threaded member.

13. The fixture of claim 10 wherein the first and second elongated wire members are each formed by bending a unitary piece of wire.

14. The fixture of claim 10 wherein the hook comprises a hook angle of about 20 degrees.

15. The fixture of claim 10 wherein the first and second elongated wire members each define a substantially straight line between the first end and the second end.
