Abstract: A hatch is provided for a fluorescent lighting fixture having a continuous reflector covering the central section. The hatch is covered by a cover of compatible contour cut through the reflector underneath the location of the ballast in the housing above the reflector. The hatch cover is finished in the same surface as that of the reflector to minimize any disruption to the intended reflective pattern and to blend visually with the reflector. Two or more preferably quick-connect fasteners attach the hatch cover to the reflector. To gain access to the ballast, the lens or diffuser is removed and then the fluorescent lamp tubes which would interfere with the hatch cover are removed. The hatch cover is then removed to gain unobstructed access to the ballast from the underside of the fixture.

Abstract: An illumination apparatus comprising an optics module wherein a driving circuit may be disposed within the proximal base portion of the optics module. The proximal base portion may further be releasably secured within an independent heat dissipating element. Such an apparatus may be very beneficial in light emitting diode (LED) applications due to its efficient conduction and dissipation of heat away from the LED semiconductor junction. Additionally, a releasable optics module comprising a plurality of LEDs and a driving circuit provides for cost efficient and environmentally friendly replacement of such a component at the end of its lifespan. The heat dissipating element (e.g. heat sink) may continue to be used, while only the optics module need be replaced or serviced as required. Precious environmental resources may thus be conserved and maintenance costs reduced while concurrently extending the lifespan of such an inventive illumination apparatus.
