What are the characteristics of LED fluorescent tube ballast
Features of fluorescent lamp ballast:
(1) the stroboscopic light is eliminated and the luminescence is more stable. It is conducive to improving visual resolution and efficiency; Reduce the visual fatigue of continuous operation, which is conducive to the protection of vision.
(2) the starting point is more reliable. After preheating the lamp tube, one starting point is successful, avoiding multiple starting points.
(3) high power factor. The power factor of fluorescent lamps above 25W conforming to the national standard is higher than 0.95. However, it should be noted that the harmonic limit specified in the national standard for lamps below 25W is very high, so that the power factor is reduced to 0.7 ~ 0.8.
Function of fluorescent lamp ballast: during starting, limit the preheating current to avoid burning the filament due to excessive preheating current, and ensure that the filament has thermoelectric emission ability. Establish a pulsed high potential. When the starter jumps off, a pulse high potential is established at both ends of the lamp to make the lamp light. Stable working current and stable discharge.
