Electronic Ballast

Q: Why do triggers and ballast produce high pressure?: Because the power supply for alternating current (ac), series inductance in the circuit, if is the resistance, tube voltage and inductance voltage is 220 v, but the nature of inductance for ac voltage has the effect of phase shift, so the tube voltage and inductance voltage more than 220 v, alternating current (ac) power is related to the phase of voltage and current, so the ac load cannot separately use the product of voltage and current, because when the inductance on the voltage and current are not synchronized.

Q: how do you argue that a fluorescent lamp ballast is good or bad: The short circuit of the ballast turns is very common, and it is very difficult to make a lamp with a new lamp, which is not measured in the multimeter. Our experience is to use a leaky bad lamp tube (the filament is good, because the old is not bright) put on, want to burn also only burn bad lamp tube, you might as well try.

Q: Daylight lamp tube do not ballast, can connect directly electricity: Characteristics of the fluorescent lamp, lamp began to ignite need a high voltage, normal light allows only by small current, the voltage is lower than the voltage at the ends of the tube. This high voltage is provided by what we call the blister.

Q: What is the difference between an LED ballast and a quartz lamp?: There's a big difference, the LED is a constant current source, and the ordinary electronic ballast is a inductance.

Q: The ballast comes out of alternating current or direct current: Is fluorescent lamp ballast, ballast resistor) on the current limiting effect and the production of instantaneous high pressure equipment, it is enameled wire on the core of silicon steel production, the iron core coil, open/close the electricity in an instant, can produce high voltage, self inductance on the electrodes at the ends of the tube (filament)

Q: Does the gold halogen lamp do not need a ballast to be able to be a ballast: It is absolutely not possible to light the lamp with a high voltage when it is lit and the voltage is lowered and the voltage is lit up and the current is limited

Q: Hello, how do you change to the lamp with the energy-saving lamp ballast: Energy-saving lamp ballast break out, it is a small circuit board, rectifier circuit there is 220 v power supply cord, there are 4 lines, on the other side for the four wire tubes, each of the four lines connecting tube is ok, don't need to be paid attention to the two wires received tubes with end of the resonant capacitance

Q: Can 40W fluorescent lamp electronic ballast be used in a 30W fluorescent lamp: Close to the number, and with the working current of 0.4 A 0.3 to drive A 30 w lamp, lamp filament flow is easy to fuse the filament to launch electronic materials on early. However, in case of no use, the best match of the lamp tube rectifier should be used.

Q: Electronic transformer is different from electronic ballast: Electronic transformer is corresponding to your load of uninterrupted power supply, according to your designed different load parameters, electronic rectifier is needless to say. Transformer transformer, ac variable exchange; The rectifier

Q: How does the selection of the ballast choose the ballast: High-pressure sodium lamps and ballast High pressure sodium lamp and high pressure mercury lamp in performance is different, not only mercury search within high pressure sodium lamp, also filled with sodium, during the lamp work, sodium and mercury in the form of liquid sodium mercury gas storage in the cold end section of the discharge tube. During the lifetime of a high-pressure sodium lamp, the power of the lamp changes as the voltage of the lamp changes. This situation is different and high pressure mercury lamp, high pressure mercury lamp in power changes lamp voltage is relatively stable, because high pressure mercury lamp light while working inside the mercury vapor pressure in saturated condition. The relationship between the voltage of the lamp and the power of the lamp is based on the excess of sodium mercury in the discharge tube. During the lamp work, only part of the mercury and sodium vapor pressure, vapor pressure also is reflected in the light of high and low voltage, it depends on the discharge tube "cold end temperature. The change of the temperature of the cold end result in the change of the vapor pressure, the change of the lamp voltage, and the change of the power of the lamp. The relationship between lamp voltage and lamp power in a certain power range is approximately linear
