Intelligent PTC thermal resistor

The PTC can be connected across the lamp resonator without changing the circuits. It can change hard start of the ballast and electronic energy-saving lamp to preheated start and the preheating time of the filament can come up to 0.4-2 seconds, which will extend the service life of the fluorescent tube by over 10 times.

Meanwhile, it can overcome the disadvantage of temperature-rising after preheating and starting of the electronic ballasts and energy-saving lamps, therefore it can be considered as another breakthrough revolution of green illumination electric appliances.

As the preheating and softly-starting component of the electronic ballasts and energy-saving lamps, the PTC thermistor can greatly increase the light switching and opeating time.
