Ignitor Metal Halide Lamp Circuit Diagram

1 how it works.

Ignitor metal halide lamp circuit diagram. 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. A halogen is a monovalent element which readily forms negative ions. Standard metal halide hps ballasts brackets wiring diagrams warranty information. Ansi code american national standards institute ansi code that indicates the electrical operating designation of the lamp which must match that of the ballast.

Metal halide lamps belong to a family of high intensity discharge hid lamps that includes mercury vapor and sodium vapor lamps. Wiring diagrams for venture standard metal halide ballast products are provided on this page. Gas discharge lamps an electric lamp. It is used internationally to start traditional metal halide lamps on 220 230v 50 hz mercury vapor ballasts.

A halide is a chemical compound of a halogen combined with an electropositive element or in the case of lamps. When full voltage is applied across the main electrodes no arc is produced at the time of switching. The ballast data tables in our catalog indicate the page number and reference letter corresponding to the correct diagram for each ballast product. 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.

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 simplest is a capacitor in series with a voltage sensitive switch that connects across the output of a lag ballast. When the supply voltage is half of the week v2 ignitor. 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.

China manufacturer of magnetic ballasts for metal halide flood lights hps flood lights. 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. 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 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. There are three basic ignitor circuits in wide use.
