A reflector holder retains a reflector that has a hole in one of its ends. The holder includes a base with a quick-connect connector extending from the base. In one version, the quick-connect connector includes a semi-arcuate flange member that extends from the base. The member has a pair of edges extending between the base and the outward end of the flange member and a mid-portion between the edges. The member also has a concave side and a convex side. A connection post extends from the mid-portion of the concave side of the end of the member away from the base, and terminates in an outward end. A pair of lock ears extend from the outward end of the connection post, with one ear extending toward each of the edges of the flange member. Each lock ear terminates in a locking end that is spaced from one of the edges so as to define a gap between the locking end and edge. Another version of a quick-connect connector includes an upper jaw and a lower jaw that extend from the base and have a gap defined between the jaws. The upper jaw has a tooth that extends across the gap. The reflector is retained in the gap with the tooth extending through the hole in the reflector.

This invention generally relates to a luminaire, and more particularly, to a luminaire having quick connect devices for holding reflectors, especially in a luminaire wherein the reflectors are adjustably positionable to increase efficiency and energy conservation.
Luminaires or light fixtures for use with fluorescent bulbs have been in use for many years. Luminaires typically have rectangular box-like bodies which are adapted to be mounted in ceilings. The luminaire is generally provided with some type of reflectors positioned longitudinally behind or alongside of the fluorescent bulb to reflect light outwardly from the luminaire into the area desired to be lit.
Recently, energy conservation and efficiency of luminaires has been improved by the use of reflectors formed of specular material, such as silver or aluminum. These materials reflect light with greater precision than previous materials and permit the lighting engineer to control the manner in which the light is reflected.
FIG. 1 is a partially exploded perspective view of a luminaire according to the invention;
FIG. 2 is a cross-sectional view of the luminaire taken along lines 2—2 of FIG. 1;
FIG. 3a is a schematic end view of the luminaire with the support unit in a lowered position producing a wide distribution beam of light;
A luminaire 10 for a fluorescent light 12 according to the invention is best shown in FIGS. 1 and 2. The luminaire 10 is suitable for mounting in a ceiling suspended or recessed in a ceiling or wall (not shown). The luminaire 10 includes a rectangular box-like body 14 having an opening for accepting a conventional lite (not shown). The body 14 has a top 16 and a pair of sides 18 which extend between a pair of ends 20. The body 14 is formed of a rigid, heat resistant material such as aluminum.
A support unit 22 is adjustably mounted to inner sides 26 of each end 20 of the body 14. Two vertically aligned rows of threaded apertures 24 are formed in the ends 20 for receiving bolts 28 for mounting the support unit 22 to the body 14.
As discussed more fully below, and shown in FIGS. 3a and 3b, the rows of apertures 24 permit mounting of the support unit 22 in a range of positions to vary the width of the projected beam of light. In a raised position shown in FIG. 3b, the support unit 22 projects a narrow width beam 30 of light. In a lower position, shown in FIG. 3a, the support unit 22 projects a wide width beam 32 of light. The support unit 22 may be angled with respect to the opening 21 for producing an asymmetric beam of light.
