Abstract

A portable fluorescent lighting device has a pair of elongated frame sections, each having a pair of oppositely positioned longitudinal bars which are joined together at their extreme ends by transverse cross bars. These two frame sections are pivotally joined together at one end. The other ends of each of the sections have removable transverse bars attached thereto to provide feet for the frame when the two sections are spread apart in a triangular configuration. A strap or chain interconnects the two sections to limit the triangular spread between these sections. Fluorescent lamps are mounted in one of the sections, these lamps being protected by the frames and having suitable transparent or transluscent cover guards.

Claims

1. A portable lighting device comprising

a pair of similar elongated frame sections, each of said frame sections including a pair of spaced apart longitudinal bar members joined together at the opposite ends thereof by transverse bar members to form a rectangular frame section,

means for pivotably joining said frame sections together at one of the ends thereof,

means for mounting at least one fluorescent lamp in one of said frame sections,

means for removably interconnecting said frame sections at a point therealong spaced from said one of the ends thereof to limit triangular spread between the sections, and

foot means attached to each of the frame sections at the other end thereof.

2. The lighting device of claim 1 wherein said foot means comprise bars, the transverse bar members at the other of the ends thereof being hollow, each of said bars being telescopically fitted in a respective one of said last mentioned transverse bar members and removably attached thereto.

3. The device of claim 1 wherein the means for pivotally joining said frame sections together comprises a hinge.

4. The device of claim 1 wherein there are a pair of fluorescent lamps mounted in said one of said sections, said lamps being positioned on the side of said one of said sections facing the other of said sections.

5. The device of claim 1 and further including means for holding said frame sections together in a folded configuration for transportation.

6. A portable lighting device comprising

a pair of similar elongated rectangular frame sections, each of said frame sections including a pair of spaced apart longitudinal bar members joined together at the opposite ends thereof by transverse bar members, the transverse bar members at one of the ends of each of said frame sections being hollow,

hinge means for pivotally joining said frame sections together at the other of the ends thereof,

means for movably interconnecting said frame sections at a point therealong spaced from the other of the ends thereof to limit triangular spread between the sections,

a bar telescopically fitted in each of the hollow transverse bar members and removably attached thereto, said bars forming feet for the frame sections,

means for mounting at least a single fluorescent lamp on one of said frame sections, said lamp being mounted on the side of said one of said frame sections facing the other of said frame sections such that the lamp is between the frame sections and protected thereby, and

means for holding said frame sections together in a folded configuration for transportation.
