Abstract
A plug-in starting aid for generating high voltage pulses in the ballast circuit of high intensity discharge lamp comprises interconnected electrical components mounted in a frame of insulating material. The frame has three terminals projecting out one side and engageable in the cooperating terminals of a connector block in which the starting in may be plugged in. The terminals are also engageable by standard mating wire terminals when the starting aid is used without a connector block.

A plug-in starting aid capable of generating high voltage pulses when interconnected to a ballast of an operating circuit for a high intensity discharge lamp, said starting aid comprising;
- (a) interconnected electrical components requiring at least three connections into said operating circuit, said electrical components include at least a charging capacitor, a resistor and a voltage-sensitive switch, said charging capacitor being connected in series with said voltage-sensitive switch for forming a series discharge loop when said plug-in starting aid is interconnected to said ballast, operating circuit with turns at the output end of the ballast said capacitor also being connected in series with at least said resistor across said lamp to form a charging loop when said plug-in starting aid is interconnected with said ballast;
- (b) a frame of insulating material in which said components are mounted said frame having a rigidity sufficient to withstand gripping and tugging without deforming so as to serve as said plug-in starting aid;
- (c) at least three terminals projecting out of one side of said frame for said interconnection with said ballast and wherein a first of said terminals is connected to said voltage-sensitive switch, a second of said terminals is connected to said capacitor and a third of said terminals is connected to the end of said charging loop which is opposite from said connection of capacitor to said resistor, said terminals being adapted to be engageable by and mated with cooperating terminals.
A plug-in starting aid for generating high voltage pulses when interconnected to a ballast of an operating circuit for a high intensity discharge lamp, said starting aid comprising;
- (a) interconnected electrical components requiring at least three connections into said operating circuit, said components being spatially disposed from each other and interconnected by leads of said components which have a spaced relationship to each other except for the portions of the leads which are connected to each other;
- (b) at least three terminals connected to said components;
- and
- (c) a frame of insulating material having base, top, and side portions, said frame having a rigidity sufficient to withstand gripping and tugging without deforming so as to serve as said plug-in starting aid, said top portion having means for supporting one end of said interconnected electrical components and said base portion having said at least three terminals lodged therein and projecting therefrom, said top and base portions providing support for said spatially disposed interconnected electrical components extending therebetween and mounted on said frame, said terminals being adapted to be engageable by and mated with cooperating terminals.
