ABSTRACT:

BACKGROUND OF THE INVENTION
Fluorescent hanging light fixtures, up to the present have a shroud fastened to the ceiling, or are mounted in recessed openings in the ceiling, and the ballast is mounted in the concave side of the shroud. This present invention discloses a hangable fluorescent light fixture with fluorescent light tubes, mounted on the concave side of longitudinal reflectors and the longitudinal reflectors attached to socket mount/wire raceway arms of the fluorescent light fixture frame.
SUMMARY OF THE INVENTION
Disclosure is made of a fluorescent light fixture
1
, having longitudinal light reflectors
4
, and each end of the light reflectors
4
, attached to socket mount/wire raceway arms
6
, attached to ends of ballast channel assembly
2
, and sockets
5
, for fluorescent light tubes
3
mounted on socket mount/wire raceway arms
6
at each end of the longitudinal light reflectors
4
on the concave side, and fluorescent light tubes
3
, inserted into fluorescent light tube sockets
5
on the concave side
4
″ of the light reflectors
4
, and the light reflectors
4
having a parabolic shape in cross section, to control down light intensity.
An object of this invention of a fluorescent light fixture assembly
1
including a fluorescent light fixture frame
12
a ballast channel assembly
2
and socket mount/wire raceway arms
6
, attached to the ballast channel assembly
2
and fluorescent light reflectors
4
, attached to the socket mount/wire raceway arms
6
, and fluorescent fixture tube sockets
5
,
5
′ attached to the socket mount/wire raceway arms
6
, and the fluorescent fixture tube sockets
5
,
5
′ located under each end of the fluorescent light reflectors
4
, and fluorescent light tubes
3
, inserted into the fluorescent fixture tube sockets
5
,
5
′ under the reflectors
4
, and an electric power source
7
into the light fixture assembly and a switch on/off
20
mounted on the ballast channel assembly, and the power connected to the ballast
11
components mounted in the ballast channel assembly
2
.
Another object is to disclose fluorescent light reflectors of various geometry to better reflect the fluorescent tube light downward.
Another object is to disclose a fluorescent light tube assembly having from one to a plurality of ten fluorescent light tubes aligned parallel side by side in an assembled fluorescent light fixture, and a reflector over each of the fluorescent tube lights.
Another object of this invention is to disclose fluorescent light tube reflectors made of polished sheet metal, or metal coated plastic, or metal coated glass.
