The benefits of electronic ballast
It's too hard to replace them now and now you're out of the ballast
The electronic ballast has the following advantages compared with the traditional inductance ballast 1. Energy saving Improve the performance of the ceramic gold halogen lamp, make the lamp tube (lamplight) more stable. Perfect protection The effect of voltage change on the power grid is very small When activated, the impact on the grid is small The potential damage of the current harmonic is small Light weight
(1) the energy saving. Fluorescent electronic ballasts, use 20-60 KHZ frequency supply tubes, more make the lamp light efficiency about 10% higher than that of power frequency (according to the length of 4 feet of tubes), and its low power consumption, make the total input power of the lamp fell about 20%, has the better energy saving effect. Electronic ballast (2) eliminate stroboscopic and glow more stable. Improves the visual resolution and improves the efficacy; Reducing the visual fatigue of continuous operation is beneficial to the protection of eyesight. (3) the starting point is more reliable. After the preheating lamp, the starting point is successful, avoiding multiple starting points. (4) the power factor is high. The power factor of 25W, above 25W of national standard, is above 0.95. However, it should be noted that the national standard has a high harmonic limit on the light tube under 25W, so that its power factor is reduced to 0.7-0.8.
The electronic ballast is essentially a dc - ac inverter, which saves electricity at the maximum possible cost in the work, and has a saving rate of 20 percent. In addition, his features than ordinary inductance ballasts can reactive power compensation, improve the efficiency of power supply, also do not damage the eyes, very suitable for work long time sitting under the light of the crowd. It can be prevented by automatically turning off the light circuit when the light circuit is unable to ignite properly. In terms of voltage, the electronic ballast can effectively control voltage, when the city lights of voltage instability, the stability of the electronic ballast quickly lamps and lanterns of current, power and so on, the prevention and control of the light burning.
Electronic ballast can be combined with the function of the generator, which can save the individual generator. Electronic ballast can also improve or eliminate the flash of a fluorescent lamp by increasing the current frequency or the waveform, such as a square wave. Electronic ballast can also be used to make fluorescent lamp use dc power source
