Igniter Circuit For Metal Halide Lamp

So once these occur with your metal halide lamp getting a replacement bulb doesn t have to be your first step.

Igniter circuit for metal halide lamp.

It is used internationally to start traditional metal halide lamps on 220 230v 50 hz mercury vapor ballasts. Although metal halide bulbs are long lasting still they wear out. Will test a pulse start light fixture with an ignitor. Checks starting pulse voltage and open circuit voltage.

Electric lamps part 08 notes is available in http zenmurali blogspot in inventor of metal halide mh lamps in the year 1912 charles p. 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 metal halide and high pressure sodium ballasts also incorporate wave shaping of the open circuit voltage to provide a higher peak voltage than a normal sine wave. Used on hps high pressure sodium mh metal halide and mv mercury vapor types of lamp.

A halogen is a monovalent element which readily forms negative ions. So when you begin to experience rapid flickering dimming buzzing and changing colors the fault could be with the bulb but most times it is a faulty ballast. Capacitor a device used in electric circuitry to temporarily store electrical charge in the form of an electrostatic field. 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.

This peak voltage along with the ignitor when used is used to start the lamp and control the lamp current crest factor typically 1 60 1 65. Both testers fit in one belt loop. Metal halide high pressure sodium and mercury vapor are types of hid lamps. 1 how it works.

A halide is a chemical compound of a halogen combined with an electropositive element or in the case of lamps. 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. 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 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.

There are three basic ignitor circuits in wide use. Suitable for hid ballast circuit with starter ignitor. Ignitor a device either by itself or in association with other components that generates voltage pulses to start discharge lamps.
