When the high pressure sodium lamp supply voltage momentary fluctuations larger decline, the lamp will self extinguish, which goes out to some of the light source can not immediately restart particular attention. Certain safety factor should be considered, so that changes are not instantaneous voltage grid below a certain allowable value. Use more HPS ballast, power factor is less than 1.2) in a large area with gas discharge lamp lighting, non-ferrous metals in order to save and improve equipment utilization, compensation should be considered in order to improve the power factor, the general method is relatively centralized compensation convenient. Wire cross-section and in the choice of lighting transformer capacity, not only to calculate the electric power consumed by the light source, and should be included in the high pressure sodium ballast power loss....

American standard metal halide lamps and metal halide ballasts different European standard, European standard metal halide or mercury lines available sodium line, you can add triggers inductively ballast; while the American standard metal halide lamp should configure a dedicated The CWA ballast, ie ahead of the peak-type (magnetic flux leakage boost) ballast, otherwise it will cause difficulty in starting, lower light efficiency, so that the color temperature instability, reduced lamp life. As long as the European standard metal halide or high pressure sodium lamp ballast coupled with mercury ballast plus flip-flops and compensation capacitor 220V 50Hz power line in our work reliably. European standard metal halide lamp according to the start pulse peak voltage can be divided into two kinds of start pulse amplitude 0.6KV-1.5KV such as HPI lamps, another 4.0KV-5.0KV as HQI-T metal halide lamp. American Standard Metal Halide Metal Halide not use electrical configuration of European standard, European standard metal halide lamps in the circuit to obtain the minimum start rms voltage (≤ 240V) can not meet the American standard metal halide lamps for electrical requirements, So America must CWA underlying metal halide bulb lighting circuit configuration (ballast type the LC peak magnetic flux leakage boost ahead of ballast, the output voltage RMS and light form factor to meet the requirements), in order to ensure the bulbs work. If the metal halide lamp not match with MH ballast.it will appear the following questions:...

The Construction of the high pressure sodium ballast: (A) by the HPS ballast silicon steel, enameled ring, skeleton cover, bottom plate (shell), terminals and other components. (B) Coil: generating induced emf. In case of power, because there is a certain resistance coil will produce power loss, the resulting rise in temperature thermal energy ballast, the ballast is easy to accelerate aging. In order to reduce the resistance of the coil, try to use high purity copper enameled wire imports. Silicon steel sheet: block conductor in a changing magnetic field, the conductor in the entire internal cause induced current, commonly known as "eddy", it will cause energy consumption, temperature rise. In the ballast, in order to enhance the strength of the magnetic induction cores are used, but because of the presence of eddy currents to be insulated from each other using a thin silicon steel lamination core formed, rather than the core piece, to reduce eddy current bring loss. Bottom: fixed installation role. Skeleton: Fixed coils, chip, easy wiring role. Terminals: wiring up the role of the ballast circuit connected in series to go....

Electrolytic capacitors: Impregnated with a paste electrolyte absorbent paper clip in the middle of two winding made of aluminum foil, a thin oxide film as a capacitor dielectric. Because there is unidirectional conductive oxide film nature, electrolytic capacitors have polarity. Various electrolytic capacitors, large capacity, can withstand a large ripple current. Capacity error, leakage current is large; ordinary high and low temperatures are not suitable in applications, should not be used at frequencies above 25kHz.,Low frequency bypassing, signal coupling, power supply filtering. Tantalum sintered tantalum electrolytic capacitor blocks as anode, electrolyte using solid manganese dioxide. Temperature characteristics, frequency characteristics and reliability superior to the ordinary electrolytic capacitor, in particular small leakage current, good storage stability, long life, capacity error is small, and the volume is small, the unit volume can be obtained under the maximum capacitance voltage product. Images on a variety of film capacitor ripple current tolerance of difference, if the damage was easy to short-circuit condition. Ultra-small parts in high reliability. High pressure sodium ballast (inductance ballast) is a core coil, when the nature of the inductor current in the coil is changed, then the magnetic flux induced in the coil will change, thus generating an induced electromotive force, the direction and the current direction On the contrary, thus hindering current changes. Used in floodlight fixture....

Magnetic Ballast is an iron coreballast, 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. Rectifier is a rectifier unit, simply means that the AC (AC) into direct current (DC) devices. It has two main functions: first, the alternating current (AC) into direct current (DC), filtered and supplied to the load, or the supply of inverters; secondly, to provide battery charging voltage. Therefore, it is at the same time play the role of a charger....

Electronic ballasts difference of raw materials and production process: James lighting energy-saving lamps,its materials, technology, equipment and quality control measures are good, we open the energy-saving lamps can see the orderly arrangement of the circuit board components, components look very good, and then look at the circuit board solder joints should be the same size, plump and shiny, does not exist joints weld, false welding, as well as circuit boards Rocker skin phenomenon. Poor energy-saving lamp circuit board components stagger components because of poor quality, the appearance of good sense, negative spot size is inconsistent, solder no gloss, circuit board copper foil with Rocker leather and so on....

Fluorescent Ballast overheating: Cause: 1. Core Ballast itself quality problems; 2. Supply voltage is too high Remedy: check first with AC ammeter current in the circuit that ballast operating current, short circuit caused as a result of ballast working current is too large, should be listed ballast renewal or repair before use. If the ballast through the current standard range, power supply is not high, you should check whether the starter is the breakdown within the capacitor, neon bulb internal electrodes are connected ride....

Single-ended compact fluorescent lamps. This fluorescent lamp, fluorescent ballast and lamp holder tightly into one (electronic ballast placed inside), in addition to damaging blow, unable to remove them, it is called "compact" fluorescent. Since no external ballast, the ballast is also within driving circuit, so this is also a self-ballasted fluorescent lamp fluorescent and fluorescent activated within. Through the entire lamp E27 lamp holder directly for other grid connection, can easily replace incandescent lamps directly. Trichromatic fluorescent lamps, fluorescent lamps halogen powder should not be used. Trichromatic lamp with high luminous efficiency, good color and longer life advantages. Although the price is expensive (about twice as expensive), but because of its high luminous efficiency, not only energy saving, lower operating costs; And because the number of reduced use of lights, lamps and ballasts save costs, but to make the lighting system reduce the total cost was first built....
