Claims

[Scope of utility model registration request]

The DC voltage from the storage battery is converted to high-frequency voltage by an inverter and boosted by a transformer.The output of the DC voltage is used to excite the filament heating transformer, and the output of the filament heating transformer is applied to each filament of the fluorescent lamp. In addition, in a fluorescent lamp that is lit by applying a boosted high-frequency voltage between filaments, a thyristor is used in the boosted high-frequency current supply circuit to provide bidirectional 1. A switching circuit configured to allow current to flow is connected to the storage battery, and a dimmer configured with a multivibrator is connected to the storage battery.
The output of this dimmer is connected to the gate of the switching circuit thyristor, and the thyristor of the switching circuit is driven by the output pulse of the dimmer to control the energization time of the high frequency current flowing through the discharge circuit, and the fluorescent lamp A dimmer device for vehicle fluorescent lights that adjusts the luminous intensity of the vehicle.
