High Intensity Discharge Lamp Circuit

Or as complex as the electronic ballasts used in compact fluorescent lamps cfls and high intensity discharge lamps hid lamps.

High intensity discharge lamp circuit. The ballast circuit includes a high voltage electronic starter. The family of arc discharge lamps includes fluorescent and high intensity discharge hid light sources. For high intensity discharge lamps high pressure mercury or sodium lamps or low pressure. A starting circuit for high intensity discharge lamps supplied from an alternating current line through a ballast inductance and in some cases a pulse transformer inductance includes a surge voltage protector svp or like voltage responsive current switching gas breakdown device connected intermediate the end of the inductance a capacitor connected to the lamp end of the inductance the.

A metal halide lamp is an electrical lamp that produces light by an electric arc through a gaseous mixture of vaporized mercury and metal halides compounds of metals with bromine or iodine it is a type of high intensity discharge hid gas discharge lamp. Ballasts vary greatly in complexity. This tube is filled with noble gas and often also contains suitable metal or metal salts. High intensity discharge hid lamps are similar to fluorescents in that an arc is generated between two electrodes.

But high intensity discharge hid lighting is as popular as ever too thanks to its high brightness excellent color temperature high lumens watt and long lifetime. When the lamp voltage. But a continuous dimmer circuit of wide range is not available. High intensity discharge hid lighting sources are important for commercial industrial and outdoor locations such as high bay parking.

By high voltage dc using static converters with semiconductor devices and specially adapted for lamps without preheating electrodes e g. Also make sure to check the voltage at the point of connection to the electrical distribution system. Operation in an overvoltage state increases wattage consumption and reduces the life of the ballast and lamp. High intensity discharge lamps hid lamps are a type of electrical gas discharge lamp which produces light by means of an electric arc between tungsten electrodes housed inside a translucent or transparent fused quartz or fused alumina arc tube.

They may be as simple as a resistor inductor or capacitor or a combination of these wired in series with the lamp. Electronic ballast circuits sense lamp operation characteristics and regulate lamp current to operate the lamp at constant wattage thus providing a more uniform. The noble gas enables the arc s initial strike. The arc in an hid source is shorter yet it generates much more light heat and pressure within the arc tube.
