Can metal halide ballast replace high pressure mercury ballast?

2015-08-25 22:50:59

High pressure sodium lamp, metal halide lamp, etc. need to include voltage larger compared to the energy supply voltage to start. Common various kinds of HID lamps are needed to add 0.six ~ five.0kV on the pulse high voltage. The electronic ignitor is usually a gadget that will generate a pulse high pressure to begin a light bulb.Once the lamp is ignited, the pulse substantial voltage disappears, and the electronic ignitor stops operating in parallel.

The electronic ignitor will depend on the ballast winding up high-voltage isolation or as a element of the starting up technique. It ought to be able to withstand repeated pulse high pressure with no injury. In some lighting lines, ballast as beginning method of a component with all the ignitor matching, this sort of ballast to be specially produced and coil ballast pump turns and connection identification ought to comply with the style and design demands from the ignitor. Otherwise, any incorrect matching can cause the lamp cannot do the job, affect the life from the lamp, result in the destruction from the ballast or ignitor series start off: the pulse high voltage created from the electronic ignitor directly applied for the bulb at both ends to begin the lamp, and the ballast is not high pressure pulse. Consequently, and no far more exclusive demands beneath 100W power HID lamps and element from the new improvement of energy-saving HID lamp ballast, a week on the ignitor pulse quantity index even now has specific specifications, multi pulse ignitor easier to start lighting, so it can be additional ideal to ensure the lamp life and functionality in line with the test: about figure 6a-d lighting lines inside the, once the rise in the power provide voltage towards the rated worth + 105%, the lamp electrical power enhanced by 12%; when the energy supply voltage up to rated value +110%, lamp electrical power about enhanced 28% to 30%. And lighting line e due to the LC peak ballast in advance, once the rise of your electrical power supply voltage to the rated worth 110%, lamp power only improve 15% about. Because the electrical power supply voltage improvements to the lamp power, so the power provide voltage should be managed inside of 105% of your rated voltage. Otherwise it is going to seriously have an impact on lamp ballast lifestyle


Metal halide lamps from the begin on the secure to a handful of minutes to view figure, lamp yet again began to after a handful of minutes to twenty minutes cooldown, in some destinations, double ended metal halide lamp configuration hot commence gadget can speedy begin lighting metal halide lamps varieties and unique, various kinds of metal halide lamps the corresponding electrical and lighting circuit necessities is not really the same, widespread lighting circuit shown in figure, metal halide lamps can't be like high pressure sodium lamp that a sorts of metal halide lamp lighting for numerous lines. Lighting circuit configuration will not be affordable may possibly make the lamp isn't going to do the job, or shorten the service daily life with the lamp, the damage to electric appliances and lighting metal halide lamps in the discharge tube to factors, there are actually two varieties of short arc (spherical) and prolonged arc (VVM), the volume of spherical metal halide lamps may be produced extremely little, and that is quick to install within a compact form of lamps and lanterns. Typically high intensity fuel discharge lamp within the electrode after aging may rectifying impact, particularly for spherical discharge tube lighting, while in the lighting circuit seem rectifying impact of lighting, will lead to the failure of ballast, the current flowing during the circuit, overheating of your ballast burned. Ordinarily tiny electrical power metal halide lamp primarily with spherical discharge tube manufacturing, so lighting lines should be safeguarding gadget, normally made use of have two strategies: initially the high pressure mercury ballast installed thermal relay protection, the second is in lighting circuit connected in series a slow fuse fuse, the fuse capacity is two occasions from the rated existing.
