Fluorescent lamp inverters
Fluorescent lamps have a negative discharge characteristic, so a stable period for controlling the current is required. This ballast is a device that applies the necessary voltage to the lamp and controls the current suitable for the lamp. 5 features 1. Immediate lighting Unlike the conventional glow starter method, the ballast function and starter function have been digitized; therefore, they light up as soon as the switch is turned on. 2. Flicker cut As the fluorescent lamp is powered by a high-frequency current, the strobing frequency of is increased and the lamp flicker that is peculiar to fluorescent bulbs is not felt. 3. Energy conservation The ballast itself consumes power in the form of copper loss and iron loss. This inverter ballast offers significant power-savings. 4. Low-rise sound The annoying high-pitched whine that is peculiar to fluorescent lamp fixtures has been eliminated using an electronic circuit instead of conventional iron-core type ballast. 5. Noise cut Measures have been taken to cut noise that interferes with other electronic components.
