Abstract
A non-blinking direct current fluorescent lamp circuit includes a switch, a bridge rectifier, a voltage regulation circuit, a filter capacitor, an ignition circuit, a contact points converter, a ballasting circuit, and a pole exchange circuit. The switch is a common switch or a contact switch circuit. Thus, the non-blinking direct current fluorescent lamp circuit does not produce electromagnetic radiation, has a steady illuminance, can be started at one time, has a higher working efficiency, can save the energy, can be worked safely, has a higher reliability, and has a longer lifetime.
