Abstract
Abstract An apparatus for connecting a high intensity discharge light to an electrical outlet has a plurality of end plates adapted to be electrically connected to an electrical outlet and to provide an electrical connection to the light. A heat sink means, and a cover means together with the end plates provide a protective enclosure for a circuit board having a ballast circuit thereon. The ballast circuit maintains a constant current flow through the light as the light becomes operational and comprises a plurality of transistor means biased both simultaneously and alternatively into conduction as the light becomes operational.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
174 words
An apparatus for connecting a space lighting high intensity discharge light to an electrical outlet socket for an incandescent light, comprising: (a) a first end plate having an electrical plug extending therefrom adapted to be electrically connected to said electrical outlet socket; (b) a second end plate spaced apart from said end plate and having an electrical socket therein adapted to provide an electrical connection to a high intensity discharge light; (c) a circuit board containing a high intensity discharge light electrical circuit thereon adapted to electrically connect said socket to said plug, said circuit board being disposed between said first end plate and second end plate and secured therebetween; (d) a heat sink means positioned laterally adjacent said circuit board and extending axially between said end plates; and (e) a cover means having a plurality of vent means therein, said cover means being positioned laterally adjacent said circuit board extending between said end plates such that said cover means, said end plates, and said hearsink form a protective enclosure for said circuit board.
Claim 2
Independent Claim
174 words
An apparatus for connecting a space lighting high intensity discharge light to an electrical outlet socket for an incandescent light, comprising: (a) a first end plate having an electrical plug extending therefrom adapted to be electrically connected to said electrical outlet socket; (b) a second end plate spaced apart from said end plate and having an electrical socket therein adapted to provide an electrical connection to a high intensity discharge light; (c) a circuit board containing a high intensity discharge light electrical circuit thereon adapted to electrically connect said socket to said plug, said circuit board being disposed between said first end plate and second end plate and secured therebetween; (d) a heat sink means positioned laterally adjacent said circuit board and extending axially between said end plates; and (e) a cover means having a plurality of vent means therein, said cover means being positioned laterally adjacent said circuit board extending between said end plates such that said cover means, said end plates, and said hearsink form a protective enclosure for said circuit board.
Claim 3
Dependent Claim
64 words
The apparatus of claim 1 wherein said high intensity discharge electrical circuit further includes a plurality of high watt resistive circuit further includes a plurality of high watt resistive means extending axially between said end plates and disposed laterally outwardly from said circuit board and in close proximity to said heat sink means such that heat generated therefrom is dissipated by said sink means.
Claim 4
Dependent Claim
49 words
The apparatus of claim 2 wherein said high wattage resistive means constitutes at least one tubular resistor, and said end plates including studs for mounting said resistor, each having a hole therein and adapted to insert into an end of said resistor such that air circulates through said resistor.
Claim 5
Dependent Claim
58 words
The apparatus of claim 1 wherein said electrical socket has nonconductive threads therein with a metal conductor ring disposed at the bottom thereof in position to make contact with conductive threads on a high intensity discharge light, said socket adapted to prevent a shock as said high intensity discharge light is seated and secured within said electrical socket.
Claim 6
Dependent Claim
39 words
The apparatus of claim 4 wherein said socket has a nonconductive rim extending endwise outwardly from said second end plate, said rim covering the metal threads of said light as said ight is seated and secured within said socket.
Claim 7
Dependent Claim
19 words
The apparatus of claim 1 wherein said heat sink means is a wall member constructed from black anodized aluminum.
