Ballast is a necessary electrical component of discharge luminescent device. It can generate instantaneous high voltage when the starter is disconnected, so that the luminescent device starts to emit light, and then limit the current to control within the rated range of the luminescent device.
Energy saving
The lamp's electronic ballast mainly USES the frequency of 20 ~ 60kHz to supply the lamp, which makes the light efficiency of the lamp increase by about 10% compared with the power frequency (according to the length of the lamp is 4 feet), and its own power consumption is low, so that the total input power of the lamp decreases by about 20%, which has better energy saving effect.
2. More stable luminescence
It is beneficial to improve visual resolution and efficiency.Reduce the visual fatigue of continuous operation, which is beneficial to protect eyesight.
3. A more reliable starting point
Preheat the lamp tube after a successful starting point, avoid multiple starting points.
4. High power factor
The power factor of fluorescent lamp that accords with national standard above 25W is higher than 0.95.However, it should be noted that the national standard sets a very high harmonic limit for lamps below 25W, so that its power factor drops to 0.7~0.8.
5. Stable input power and output luminous flux
High quality products have good voltage stability performance, when the power source, voltage deviation is large, still can maintain the constant power of the light source, stable illumination, is conducive to energy saving.
6. Extend lamp life
The constant power of high quality products and the drop of tube current, as well as the reliable starting point can prolong the life of the lamp.
