Abstract

Disclosure is made of a fluorescent light fixture having longitudinal light reflectors and each end of the light reflectors attached to socket mount/wire raceway arms attached to ends of ballast channel assembly and sockets for fluorescent light tubes mounted on socket mount/wire raceway arms at each end of the longitudinal light reflectors on the concave side, and fluorescent light tubes inserted into fluorescent light tube sockets on the concave side of the light reflectors. The geometry of the cross section parabola of the reflectors is identified.

Claims

1. Fluorescent light fixture comprising;

a—

longitudinal light reflectors and each end of said longitudinal light reflectors attached to socket mount/wire raceway arms,

b—

said socket mount/wire raceway arms attached to ends of ballast channel assembly,

c—

light tube sockets for fluorescent light tubes mounted on said socket mount/wire raceway arms at each end of said longitudinal light reflectors in the concave side of said longitudinal light reflectors and

d—

said fluorescent light tubes inserted into said light tube sockets in the concave side of said longitudinal light reflectors.

2. Fluorescent light fixture of claim 1, further consisting of;

a—

a plurality of said longitudinal light reflectors and each end of said longitudinal light reflectors attached to said socket mount/wire raceway arms and,

b—

two of said socket mount/wire raceway arms attached one on each end perpendicular to ends of said ballast channel assembly,

c—

said light tube sockets for said plurality of fluorescent light tubes mounted on said socket mount/wire raceway arms at each end of said plurality of longitudinal light reflectors in the concave side of said plurality of longitudinal light reflectors,

d—

said plurality of fluorescent light tubes inserted into said light tube sockets in said concave side of said light reflectors,

e—

slots in said longitudinal light reflectors for indirect lighting and

f—
