Q:The power of fluorescent lamp tube and the relation of ballast
The power of the fluorescent tube is the rated power of the bulb; The power indicated by the ballast is the power of the fluorescent tube that is used for it.
Q:The principle of the rectifier
The inductance ballast When the switch is closed circuit of 220 v, 50 hz ac power, the electric current flows through the ballast, lamp filament to the starter filament heating (at the beginning of the starter is broken, due to exert a greater than 190 v ac voltage, the starter has jump of gas inside the bubble inside the arc discharge, the bimetallic strip heating deformation, two electrodes together, form a path to the filament heating), when the starter of the two electrodes together, since there is no arc discharge, bimetallic strip cooling, poles apart, due to the inductance ballasts are perceptual, when the circuit is suddenly interrupted, duration on both ends of the lamp will produce about 1 ms pulse voltage 600 v to 600 v, the exact voltage value depends on the kind of light, in the case of discharge, the ends of the lamp voltage drop, immediately the lamp current limiting effect on the ballast on the one hand, on the other hand make the supply voltage and the working current of the lamp produces 55. - 65. The phase difference of the lamp, which keeps the lamp's secondary start voltage, makes the lamp more stable.
Q:Can ballast be replaced with the usual daylight tube ballast?
Yes, the power is the same.Completely, the ballast power is not small.I hope my answer will help you
Q:Can the eyelet lamp do not use a ballast
National electric light source quality supervision and inspection center of Beijing the lamp that shield an eye had special spot market, spot check results show that 80% of the products on the market is poor quality raw materials, such as unqualified components, components. The design of the circuit is not in accordance with the specification; The curing agent, the flame retardant is not enough, the heat resistance is not qualified; Light shading, low power, high frequency flash, etc. Inferior the lamp that shield an eye on children and adolescents eyesight caused serious harm, although not can appear in the short term, but its security hidden danger to the human body and the impact on the normal product is obvious.
Q:Do you use a 50Hz ballast for the lamp of 220v 60Hz
It may not be possible, depending on the structure of the ballast itself. A, if the lamps and lanterns is used within the ballast is the inductive limit flow (e.g., low cost design of high pressure mercury lamp), suitable for the occasion of 60 hz, the inductance may be applicable to the 50 hz occasions about 20%, so the current rating of 20%, probably more than design flow effect and may make core magnetic saturation, led to the decrease of the inductance further... The resulting flow of light is damaged;
Q:How to use digital multimeter to measure the ballast of fluorescent lamp
If the inductance ballast, multimeter to resistance, measurement on both ends of the ballast is pass, but the resistance is not 0, is not very big, the ballast winding can be thought of as normal. Any line should not be able to detect the shell.
Q:Maintenance of electronic ballast for energy-saving lamps
Energy-saving lamp electronic ballast is replace inductive rectifier products, its characteristic is to use two 13003 amplification, each other is a filament for 120 volts, in the middle of the two filament series a 0.01 UF ceramic tile capacitance, make its light. Thank you to adopt
Q:What's the difference between a ballast and a starter?
Now the suction light is usually used in ballast, and the ballast is covered with the starter, providing a transient high voltage start-up for the fluorescent lamp. Meanwhile, the ballast contains electronic components such as filtering. For your home after open flash lamps and lanterns, it is possible that the voltage instability (see other, etc. If there is a similar situation, there is no word is other reasons), the reason of lamps and lanterns is very small, but you can change a try, generally this is the reason of the ballast
Q:Can be able to change the power of fluorescent lamp by electronic ballast
Fluorescent lamp tube, has its own power, namely optimal lamp tube voltage, with current. In a certain range, changing the current can change the power, but the efficiency of luminescence is reduced, and it is not economical to use a watt of electricity. If the current is too small, the light will go out; If the current is too large, the tube will burn. So, try not to do that.
Q:The ordinary ballast circuit of a daylight lamp is more efficient than the electronic ballast circuit.
Launch within the tube material run out and broken filament) often occur, personally think that the domestic electronic ballasts quality is very poor, in contrast is energy-saving, but not to save money.
We are a well-known enterprise specializing in the production and sales of high-grade Ballast. Since the establishment of our company, we have been devoted to setting up a good reputation in the world.
