When the switch is closed circuit 220V50Hz AC power is applied, the current flowing through the high pressure sodium ballast, lamp filament to filament heating ignitor(ignitor is disconnected from the beginning, due to the application of an AC voltage greater than 180V so jump ignitor arc discharge gas inside the bubble, jump vesicles bimetal thermal expansion deformation, two electrodes close together to form a pathway to the filament heating). When the starter of the two electrodes close together, because there is no arc discharge, the bimetal cooling, disconnect the two electrodes, the core ballast is inductive, the moment when the two electrodes is disconnected, the circuit current suddenly disappeared, so ballast generates a high pulse voltage, the power supply voltage is superimposed upon it, added to the tube ends, so that the lamp inside the inert gas ionization caused by arc discharge. (High pulse voltage time of about 1ms 600V ~ 1500V, its exact value depends on the type of lamp voltage). In the course of normal light, a stabilizing ballast inductance current in the circuit. Ballast is an iron core coil, when the nature of the inductor current in the coil changes, the magnetic flux induced in the coil will change, thus generating induced electromotive force in a direction opposite to the direction of the current, thereby preventing current changes, and thus play a role in stabilizing current limiting....

Sodium lamp use sodium vapor discharge electric light visible. Sodium lamp is divided into low pressure sodium and high pressure sodium lamps. Low pressure sodium vapor pressure of not more than the work of a few par. Low pressure sodium discharge radiation concentrated in the 589.0 nm and 589.6 nm, two pairs of D lines, they are very close to the human visual curve the highest value (555 nm), so its high luminous efficiency. High pressure sodium vapor pressure greater than 0.01 MPa work. HPS is too strong for low pressure sodium lamp monochrome, color is very poor, and other shortcomings of the discharge tube is too long developed. High pressure sodium ballast is an iron core inductor, inductance coil when the nature of the current changes, the magnetic flux induced in the coil will change, and thus the induced electromotive force in a direction opposite to the direction of the current, thereby preventing the current changes....

Electronic ballasts for its remarkable energy-saving effect, small size, light weight, high reliability, has been in compact fluorescent lamps, fluorescent lamps, integrated lights are widely used, and achieved good economic and social benefits, along with the continuous development of electronic technology reliability of electronic components continues to improve, and significantly reduce the cost, HID lamp electronic ballast will become an important part of the green lighting project. Energy saving: Under the same conditions, to get the same illumination, compared to conventional magnetic ballast, HID lamps with electronic ballasts, the input power can be reduced by 10% or more generally, because the lamp uses high-frequency or low-frequency square-wave current lighting work, the luminous efficiency of the system is improved. Electronic ballasts own loss, general product efficiency up to 93%. High power factor up to 0.99, reducing transmission line losses....

HID Electronic ballast with magnetic ballast advantages and disadvantages: 1, to ensure lamp life: the traditional core and coil ballast when aging or deterioration, it provides current may be too large, easy to damage the lamp, resulting in shortened life expectancy, CDM lamp priced quite high, if the use of electronic town flow control is easier to ensure lamp life. So long as there are 5,000 records lamp replacement for industry, the use of electronic than the traditional cost-effective. 2, anti-discoloration: If you use conventional copper iron ballasts, after 2,000 hours of use, metal halide color temperature will begin to shift, even up to 30% more color, have a serious impact on store merchandise, the use of electronic ballasts, to before the end of lamp life, color temperature changes confined within 5%. 3, power: compare and traditional copper iron ballasts, electronic can save 10% to 20% of the cost of electricity. 4, light weight: compare and traditional copper and iron ballast, electronic weighing about traditional 1/3. Especially suitable 35w and 20w small wattage metal halide or rail-mounted luminaire design.  HID electronic ballasts and fluorescent electronic ballast design differs metal halide electronic ballast fluorescent lighting electronic ballast operating frequency:> 20K Hz above <250 Hz Operating circuit constant current circuit constant power circuit drive half full p p resonance resonance  three, electronic ballasts and traditional magnetic ballasts compare 6:00  1, power: electronic ballast can save 10% to 20% of the electricity.  2, withstand voltage fluctuation: Electronic ballast power factor because the initiative Lulu, can withstand a wide range of voltage variation, while traditional ballast can only afford 10% range.  3, Light weight: The weight is about the traditional electronic ballast ballast 1/3.  4, strobe: electronic ballast without lamp flicker problem.  5, ignitor: No ignitor or electronic ballast.  6, compensation capacitors: electronic ballast without compensation capacitors....

Fluorescent tubes, diameter finer, starter ignition voltage is higher, the higher technical performance requirements for ballast. Diameter greater than T8 (including T8) fluorescent tubes, starter ignition voltage is low. Relative to 220V, 50Hz frequency alternating current, consistent starter ignition voltage is less than 1/2 power supply voltage law. Inductive ballast can be used for starter ignition operation. Diameter less than the T8 fluorescent tube, high voltage ignition starter. Relative to 220V, 50Hz frequency alternating current, does not meet the starter ignition voltage is less than 1/2 power supply voltage law. Inductive ballast can not be used for starter ignition operation. Diameter less than the T8 fluorescent tubes, electronic ballast must match. By an electronic ballast, strik pressure, the fluorescent tube breakdown ignited. Later, by the electronic ballast, fluorescent tubes lit drive operation. Fluorescent electronic ballast, electronic circuit mode will generally be based on 50Hz or 60Hz power rectified to DC power, and then to self-oscillation mode driver transistor to turn on - turn off generating high frequency switching mode power supply, and an inductor and resonant capacitor in series to produce a high voltage to excite fluorescent starter and has automatic protection circuit, when replacing the lamp or the lamp is damaged, it will automatically stop the transistor action, without generating high voltage in order to avoid danger....

Metal halide lamp is based on the improvement of high-pressure mercury lamp. High-pressure mercury lamp with high luminous efficiency, but the light color is poor. Its light blue, green, red component is missing. In order to improve the high-pressure mercury lamp color, in the early sixties people will be added to the metal in the form of high-pressure mercury halide go. Weakness improved high pressure mercury lamp, a metal halide lamp. So metal halide lamps are high pressure mercury lamp and halogen works developed on the basis of new efficient light sources. It is high luminous efficiency, light color is good, and can be designed and manufactured according to the different needs of the desired light color. Thus, not only in the application of lighting technology can also be used for a variety of special needs radiation.
