A halide is a chemical compound of a halogen combined with an electropositive element or in the case of lamps.
When the supply voltage is half of the week v2 ignitor.
A halogen is a monovalent element which readily forms negative ions.
Schematic diagram of a metal halide lamp is shown below.
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.
Ansi code american national standards institute ansi code that indicates the electrical operating designation of the lamp which must match that of the ballast.
It is used internationally to start traditional metal halide lamps on 220 230v 50 hz mercury vapor ballasts.
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.
Wiring diagrams for venture standard metal halide ballast products are provided on this page.
Gas discharge lamps an electric lamp.
The simplest is a capacitor in series with a voltage sensitive switch that connects across the output of a lag ballast.
How does a metal halide lamp work.
1 how it works.
The ballast data tables in our catalog indicate the page number and reference letter corresponding to the correct diagram for each ballast product.
Metal halide lamps belong to a family of high intensity discharge hid lamps that includes mercury vapor and sodium vapor lamps.
There are three basic ignitor circuits in wide use.
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.
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.
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.
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.
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.
