The starter is used by many fluorescent Lights, and most of them have the same with the Light. The Light will not turn on when it is not working. The function of the starter is to instantaneously short-circuit, so that the inductor generates a high voltage and breaks down the gas in the Light , Let the electrons pass, making the lighting. Is it okay to use a starter for the Light? What is the working principle of the Light starter?
Is it okay to use a starter for the Light?
It mainly plays the role of heating the filament. The heated filament can be lit up at a source voltage of 310V. If the filament is hot enough, 200V can also light 40W fluorescent Light. There is also a boosting effect, but not the main one.
The role of the starter is to instantaneously short-circuit, so that the inductor produces a high voltage, breakdown the gas in the Light tube, and let the electrons pass. Therefore, it can only work if it is used in conjunction with an inductor.
The starter is used in the fluorescent ballast circuit of the inductive ballast, and it acts as an automatic switch: the Light current passes through the starter, where the neon bulb lights up, and the bimetal is bent after heating, the circuit is automatically disconnected, and the current in the inductor When it is suddenly interrupted, a higher self-inductance potential is generated, and the Light is lit after superimposed with the external power supply. After the Light is lit, the current flows through the Light and no longer passes through the starter. At this time, removing the starter does not affect the lighting of the Light.
The power range of the Light used by the starter is very wide, and it can usually be used in 8-40 watt fluorescent Lights. In the electronic ballast fluorescent Light circuit, the starter is not needed. Is it okay to use a starter for the Light? Instead of using a starter, electronic ballasts are used to generate instantaneous high voltages through electronic circuits.
Without starter method:
Keep the original circuit of the fluorescent Light, and lead out the two ends of the original starter, and connect a normally open lockless key switch to make the “Qihui” button (but be sure to retain the inductive ballast and circuit). When it is necessary to turn on the light, turn on the power with the original power switch (on), press the “Qihui” button, and then release, the ballast will generate an instantaneous high voltage due to the inductance on / off, causing the Light The gas was broken and ignited.
You can replace the rectifier with electronic originals, which can also make the fluorescent Light light up, and you can not use the starter.
However, the withstand voltage of electronic components should be higher (more than the peak voltage). The heat dissipation is better, which can extend the life.
The starter is a device that uses preheating to increase the voltage across the Light to light the Light. The starter capacitor is one of the extended parts of the starter. The function of the starter capacitor is obvious, mainly for protection effect.
Working principle of Light starter:
Activate the inert gas in the Light tube with instantaneous high pressure and activate the phosphor on the wall to emit light. The function of the ballast in the picture is to generate high-voltage self-induced electromotive force when the starter is turned on and off, and the filament in the Light tube is used to heat the inert gas. The voltage of the two ends of the starter when the circuit is just connected to the power supply is greater than 65V. The neon gas in the starter bubble starts to heat up, and the U-shaped bimetallic sheet is heated and straightened. b After the two ends are connected, the voltage in the bubble disappears, the U-shaped bimetallic sheet becomes cold and retracts, and the contact is disconnected. The ballast generates an instantaneous high voltage when the starter is disconnected to activate the fluorescent tube to emit light. After the Light glows, the voltage across the starter remains below 65V and no longer operates. Short-circuiting the starter seat with a wire is to simulate the working process of the starter.
