Abstract

A kit for replacing existing incandescent fixtures with a 2 D fluorescent fixture includes a plate with a ballast/transformer on the upper surface and a 2 D lamp socket on the lower surface. The ballast/transformer is coupled to the source of power through a separable connector which can be terminated either in an electrical plug which fits into an existing socket or, using conventional wire nut connectors, can be "hard wired" into place. Spring hangers, which can be attached to existing housing features, are loosely held to the upper surface of the plate so that in a first orientation, the plate is below the housing and access may be had to the housing interior and in a second orientation, the plate is held secure against the housing. A diffuser globe can be provided for installations which are not recessed.

Claims

1. Apparatus for converting an incandescent lighting fixture that is installed in a receptacle/housing, including bracket means that is installed within a ceiling, to a fluorescent fixture comprising:

a. a base plate having an interior surface and an exterior surface;

b. a ballast/transformer assembly mounted to said base plate interior surface;

c. a fluorescent lamp socket mounted to said base plate exterior surface and adapted to be electrically connected to said ballast/transformer assembly;

d. a separable connector assembly electrically coupling said ballast/transformer assembly to the permanent electrical wiring adapted to connect to the incandescent fixture; and

e. spring hangers coupled to said base plate and adapted to attach to the receptacle/housing using existing receptacle/housing structural elements for engaging said base plate in first and second orientations, said first orientation allowing access to the interior of the receptacle/housing above said base plate and said second orientation holding said base plate secure against the receptacle/housing and blocking access to the interior of the receptacle/housing,

whereby an existing receptacle housing for an incandescent light fixture can be adapted to accept a fluorescent light fixture.

2. The apparatus of claim 1, above, further including gripping means to accept a diffuser shell for enclosing said base plate and said fluorescent lamp socket.

3. The apparatus of claim 1, above, wherein said spring hangers are loosely retained within structural loops fastened to said plate interior to allow freedom of orientation of said spring hangers.

4. Apparatus for converting an incandescent lighting fixture that is installed within a receptacle/housing that is in a ceiling, to a fluorescent fixture comprising:

a. a base plate having an interior surface and an exterior surface;

b. a ballast/transformer assembly mounted to said base plate interior surface;

c. a fluorescent lamp socket mounted to said base plate exterior surface and adapted to be electrically connected to said ballast/transformer assembly;

d. a separable connector assembly electrically coupling said ballast/transformer assembly to the permanent electrical wiring adapted to connect to the incandescent fixture; and

e. attachment means for attaching said base plate to the receptacle/housing,

whereby an existing receptacle/housing for an incandescent light fixture can be adapted to accept a fluorescent light fixture.

5. The apparatus of claim 4 above, further wherein said attachment means include a strap element fastened to said base plate interior and fastening means connected to said strap element and adapted to engage an existing slot in the receptacle/housing for securing the assembly to the receptacle/housing.

6. The apparatus of claim 4 above, further wherein said attachment means include spring hangers coupled to said base plate and adapted to attach to the receptacle/housing using existing receptacle/housing structural elements for engaging said base plate in first and second orientations, said first orientation allowing access to the interior of the receptacle/housing above said base plate and said second orientation holding said base plate secure against the receptacle/housing and blocking access to the interior of the receptacle/housing.
