Ignitor Metal Halide Lamp Circuit Diagram

When full voltage is applied across the main electrodes no arc is produced at the time of switching.

Ignitor metal halide lamp circuit diagram. Ballast a device required by electric discharge light sources such as fluorescent or hid lamps to regulate voltage and current supplied to the lamp during start and throughout operation. The lamp uses mercury vapor to create the powerful light like the high pressure mercury vapor but includes other metals halide salts to improve the color. Metal halide lamps belong to a family of high intensity discharge hid lamps that includes mercury vapor and sodium vapor lamps. Like fluorescent lamps hid lamps produce light by the excitation of a gas confined between a pair of electrodes and require a ballast to limit current draw and to provide proper starting and operating voltages.

Standard metal halide hps ballasts brackets wiring diagrams warranty information. It is the early use of high pressure sodium lamp electronic ignitor in recent years two way thyristor tube ignitor commonly used electrical schematic diagram its working principle is as follows. Wiring diagram for my yardblaster conversion from mercury vapor to probe start metal halide here is a rough sketch of how i wired my philips si51 750v 2 wire parallel ignitor to my american electric r175m mercury vapor yardblaster fixture to convert it to probe start metal halide. 250 w hid metal halide electronic ballast introduction this application note describes the two stages of electronic ballast for a 250 w hid metal halide lamp.

The auxiliary electrode or starter electrode near the main electrodes attached to the glass stem creates initial discharge between them. A halogen is a monovalent element which readily forms negative ions. The combination of wires to be used for a specified voltage will be indicated in the wiring diagram and often labeled on the wires too. Ansi code american national standards institute ansi code that indicates the electrical operating designation of the lamp which must match that of the ballast.

Gas discharge lamps an electric lamp. The ballast data tables in our catalog indicate the page number and reference letter corresponding to the correct diagram for each ballast product. The ballast is composed of a boost converter power factor controller pfc working in fixed off time and an inverter composed of a full bridge that drives the lamp at low frequency square. 1 how it works.

Schematic diagram of a metal halide lamp is shown below. There are three basic ignitor circuits in wide use. China manufacturer of magnetic ballasts for metal halide flood lights hps flood lights. When the supply voltage is half of the week v2 ignitor.

How does a metal halide lamp work. The simplest is a capacitor in series with a voltage sensitive switch that connects across the output of a lag ballast.
