PANEL OE rLING AND LIG~T FIXTURE

BACKGROUND OF THE INVENTION
The present invention relates to a light fixture for a ceiling, and more specifically to a novel combination of such light fixture with a suspended ceiling. Such suspended ceiling ordinarily consists of hangers which position and support carriers in a level plane and to these carriers panels of several available profiles are a tached.
It has been the practice up to now to have light fixtures 1~ suspended below the ceiling since the supportive chains for the carriers can pass through gaps bet:ween the ceiling panels.
However, the appearance of the ceiling is interrupted by bulky fixtures for housing one or more lamps.
Another alternative has been to create rectangular op~nings ~or rectangular fixtures in~hich case the bottom o the fixtures are flush with or above the ceillng panels.
Random size fixtures might not match the,openings created by removing one or more panels. Th~ fixtures suspended from the structural ceiling above the panels, for several reasons, may not fall in line with the openings made or left in the suspended ceiling~ Such openings interrupt an otherwise smooth ceiling and leave the impression that the ceiling is unfinished. This is especially so when the lights are turned off, It is, therefore, an object of the present invention to provide a new light fixture and ceiling combination which will overcome the above-mentioned disadvantages.
More specifically, it is an object of the present invention to provide a ceiling with panels, in combination with a light fixture and installation ~eaturesr which will not interrupt the smooth appearance of a ceiling.

DETAILED DESCRIPTION OF PREFERRED_EMBOD_MENTS
The suspended ceiling illustrated in Figures 1 and 2 comprise channels or carriers 10 suspended from a structural ceiling of a building or the like, by chains, rods, wiresr or cables 12. Each channel 10 is pro~ided with groups of slots 14 receiving therein ceiling panels 16 which are usually made of aluminum or other metal and extend across one or more channels 10, as indicated in Figure 2. The structure described so far is well-known in the art.

Accoxding to the present invention a lighting fixture is provided which combines in a novel manner with the ceiling.
More specifically, a standard fluorescent tube 18 with socke~s 20 and a housing 22 for the balask and other necessary items, is inserted in a box 24 having in one end or side thereof a hole 26 for electxical wires 28 providing electric power to the tube.
Box 24 is also provided with brackets 30 at each end. Each bracket has oblong holes 3~ permitting vertical adjustment of a horizontal plate 34 of the bracket relative to the housing 24.
In this manner the le~el of the box relative to the suspended ceiling can be adjusted by loosening and tightening screws 36. rrhe entire box 24 is fixed to carriers 10 by means of screws 38. It is to be understood that the box can be adapted to different available lengths of fluorescent tubes. Ordinarily a standard ~our-foo~ fluoresce~t tube i~ used. It i~ also understood that several of such tubes may be combined end to end or next to each other, as illustxated in Figs. 4 and 5. In Fig. 4 box 24a contains two fluorescant tubes 18 in a row, while in Fig. 5, two rows of two 1uorescent tubes 18 are arrange~ side by side. The ceiling panel immediately below the light fixture, as for instance the ceiling panel 4G in Figure 1, is made of plastic transparent or translucent material, such as PVC, acrylic co polymer styrene or polystyrene that is non-shattering and flame retardant, instead of the aluminum panel 16 used throughout the remai~der of the ceiling.
The box 24 and the lighting fixture 18, 20, ~2 axe both painted white so as to reflect the majority of the light through the lens and with its pro~iled end pieces no light is dissi~ated above the ceili~g. It is, of course, understood that the lens could be tinted to give a pink (waxm) light, or blue (cool) light or green (restful) light.
~ ~2~8~ 1 1The lens 40 matches the aluminum panels when the light is turned off. The light fixture serves as a reflector fastened to the suspended ceiling and transmits light only through the panel directly below it. The closed ends of the box conform to the shape of the panel.
The panels 16 and 40 do not have to have an essentially flat bottom as shown in Figs. 1 and 2, but may have different shapes. Fig. 3 shows an alternative embodiment in which the panel 42 is essentially triangular. The end panel 44, of the box for ~;
lo the fluorescent tube ~s adapted accordingly.
While Figs. 1 to 3 show a lens madP of a plastic transparent or ~ranslucent material which is plain throughout the present invention contemplates the use of other such lenses. For example, Fig. 6 shows an aluminum paneI 46 having as essentially rectangular cut-out 48 and receiving therein~above cut-out 48 a lens 50. Lens 50 comprises lonqitudinal and transverse ribs 52 and 54 respectively leaving openings 56 thereb~tween (see also Fig. 8). Ribs 52 and 54 are wider at the top than at the bottom and each wall confining an opening S6 has a highly polished metallized finished surface to form a mirror. The lens is made from virgin acrylic or polystyrene, with said metallized surface covered by a clear lacquer.
In still another form shown in ~iguxe 7, a U-shaped metal panel 58 (such as aluminum) having two cut-outs 60 receives a lesn 61 over each opening. The lenses may have a glass-like surface characteristic or may have those shown in Figure 9 or 10, i.e. a honey-comb like or some geometric profiled surface 64 or an irregular diffusing surface 66. Lenses 61, 62 and 6 are made from virgin acrylic, styrene, or polystyrene.
Fig. 11 shows in an exploded, perspective view a modified ceiling and lighting ixture combinationO Instead of the ~:7' 4-r 1 ~2~8~
1 essentially U-shaped channels shown in Fig. 2 the combination shown in Fig. 11 has U-shaped channels 70 opening upwardly.
Ceiling panels 72 are suspended from ~he channels by fingers 74.
Each finger simultaneously supports a flange 76 of one panel and flange 78 of an adjacent panel.
The panel below a lighting fixture is provided with a cut-out 80 to be covered with a lens 82 of a material similar to or like that of lenses 61, 62 or 68 shown in Figs. 7, 9, and 10, respectively. In a manner similar to that described above the lighting f~ture is mounted in a box 84 having brackets 86 to be supported on channels 70.
It is, of course, to be understood that the present invention is not limited to the embodiments shown and described above but only by the scope of the appended ~laims.
