A lighting apparatus is provided that includes a bulb housing having a first surface, and a second surface, wherein the first surface is at an angle greater than zero degrees, but less than or equal to forty-five degrees from a second surface, and wherein the second surface is parallel to a plane on which the bulb housing is to be mounted, and a receptacle connected to the first surface. A quad-tube fluorescent bulb is accommodated within the receptacle. When the angle has a value of forty-five degrees, three tubes of the quad-tube fluorescent bulb are exposed and seventy-five percent of the lighting produced by the quad-tube fluorescent bulb is direct light and twenty-five percent of the lighting produced is indirect or reflected light.

The present invention relates generally to a lighting apparatus. More particularly, the present invention is directed to an apparatus and method for maximizing illumination from fluorescent bulbs.
Compact fluorescent bulbs utilize less energy than incandescent bulbs designed to produce the same amount of light. Consequently, compact fluorescent bulbs generate less heat in outputting light than comparable incandescent bulbs. As a result, compact fluorescent bulbs are more energy efficient than comparable incandescent bulbs. Compact fluorescent bulbs will also last up to ten times longer than comparable incandescent bulbs.
A quad-tube fluorescent bulb is one example of a compact fluorescent bulb. Quad-tube fluorescent bulbs may be an assembly of four single tubes in a square arrangement, or an assembly of two bent (“U”-shaped) fluorescent tubes arranged in a square-like arrangement.
FIG. 1 illustrates a side plan view of a lighting apparatus in accordance with the present invention.
FIG. 2 illustrates a lighting apparatus in accordance with the present invention.
FIG. 3 illustrates an exploded view of a ventilation unit including a lighting apparatus in accordance with the present invention.
Referring now to the figures wherein like reference numerals indicate like elements, there is shown in FIG. 1 a lighting apparatus 10 in accordance with the present invention. The lighting apparatus 10 includes a bulb housing 12. The bulb housing includes a base surface 14 and two side surfaces 16. Receptacles 18 are coupled to the side surfaces 16 of the bulb housing 12.
Each receptacle can accommodate, for example, four individual lighting elements, two bent tube lighting elements, or a single lighting element that includes, for example, two bent tube lighting elements or four single lighting elements. Shown in FIG. 1 are four lighting elements 20 that are part of a lighting assembly that includes four lighting elements. In an exemplary embodiment of the present invention a quad-tube fluorescent bulb is utilized, for example, model FQ 13E41U/2 by Panasonic, model PLC 13W/41/USA by Phillips, model F13DBX23T4/SPX41 by General Electric and/or model CF13DO0/841 by OSRAM SYLVANIA. It should be understood that the number of surfaces 14, 16 of the bulb housing 12 and the number of receptacles 18 coupled to the housing may vary.
In an exemplary embodiment of the present invention, the receptacles 18 are placed on a side surface 16 that is at an angle 22 having a value that is greater than zero degrees but less than or equal to forty-five degrees from a horizontal surface, such as the base surface 14 of the bulb housing 12.
