Ballast definition

Ballast means an electronic light source control gear between supply and light source to stabilise the electrical current of a gas-discharge light source;

Ballast means a device used with an electric discharge lamp to obtain necessary circuit conditions, such as voltage, current, and waveform, for starting and operating the lamp.

Ballast means a device used with an electric discharge lamp to obtain necessary circuit conditions (voltage, current and waveform) for starting and operating.

Examples of Ballast in a sentence

More Definitions of Ballast

Ballast means one or more components, either between supply and light source or integrated with the light source, to control the electrical current of a gas-discharge light source.

Ballast means lamp control gear inserted between the supply and one or more discharge lamps which by means of inductance, capacitance or a combination of inductance and capacitance, serves mainly to limit the current of the lamp(s) to the required value.

Ballast means crushed or broken stone, solidified furnace slag, ashes, screenings, stone chippings, and other like material sold, conveyed, or otherwise dealt with in the course of trade, and used, intended to be used, or capable of being used, for road or building construction or for similar purposes;

Ballast means the electrical supply of the gas-discharge light source. This ballast may be partly or completely inside or outside the headlamp.

Ballast means a device used with an electric discharge lamp to

Ballast means a device which serves mainly to limit the current of the lamp(s) to the required value in case it is connected between the supply and one or more discharge lamps. A ballast may also include means for transforming the supply voltage, dimming the lamp, correcting the power factor and, either alone or in combination with a starting device, providing the necessary conditions for starting the lamp(s);

Ballast means an electrical device containing capacitors for the purpose of triggering high-level electrical components. A ballast provides electrical balance within the high-level electrical compo- nent circuitry.
