Delay-Time PTC Thermistors for Lamps and Lanterns
Features of Products:
With the development of global energy conservation, PTC Thermistors for electronic ballast softly starting has attracted more and more public attention. The traditional ballast starting, added high-pressure filament material suddenly without preheating, will take serious sputter and loss, and make the light turn black and scrap ahead of time. However, the electronic ballasts we have researched and developed, have been through preheating and high pressure. Lighting the tube, the filament material can only produce slight sputter, and can extend the light life span greatly. Tests by some authority organizations have indicated: Using PTC Thermistor to delay starting, can change the hard starting to pre-heating starting of the electronic ballasts and electronic power-saving lamps. The pre-heating time of wires can reach to 0.4-2.0 seconds. Such electronic ballasts can make the lamp service prolonged to more than 5 times.
Working Theories:
When the high frequency shaking return circuit has been put through, and because PTC is in a cold state and Rt is in a low state of resistance, its resistance value is far lower than that of C2, and the light pressure is smaller than that of starting it. Then current through C1, RT forms the return circuit-preheating filament. Meanwhile, PTC Thermistor is heated to above the Curie temperature, Rt heating temperature exceeding the switch temperature TSW and leaping to the state of high resistance too. Its resistance value is far higher than that of C2, and the current goes through C1, C2, forming the return circuit and causing LC resonance and producing high pressure and lighting the tube. Generally speaking, to delay the preheating time, we should select the relatively lower resistance, taller Tc point and bigger PTC Thermistor.
Main Applications
Products are mainly applied in fluorescence lamp electronic ballasts, electronic power-saving lamps, and triggers.
