Abstract

The invention discloses a multifunctional ballast, which comprises a video display. A bus is composed of setters, a central controller, a driver monitor and door side displays, wherein the front door and the rear door of the bus are provided with the setters and the door side displays respectively; electron tubes are added to the central controller and the driver monitor, the central controller processes the received information and transmits the information to the door side displays and the driver monitor, and the driver informs a passenger to get off the bus or controls the vehicle to move through the video display; the setter is provided with at least two buttons, and the button is internally provided with a light emitting electron tube and a sensor; the central controller is provided with a device which integrates numbers and stops, and the numbers and the stops are transmitted to the door side displays and the driver monitor; the door side display is provided with a liquid crystal display screen; and the driver monitor is provided with a number device. A device for enabling the passenger and the driver to communicate exists. The structure is simple, convenient and practical, and the cost is low.

Description

technical field [0001] The invention relates to a multifunctional ballast, in particular to a multifunctional ballast for fluorescent lamps. Background technique [0002] In the current lighting industry, the existing general-purpose electronic tubes are composed of electrical components such as power capacitors, normally closed thermal switches, and thermal resistance coils. This electronic tube has strong vibration noise and temperature rise, and has light flickering. When the power supply is turned on, the lamp cannot be lighted up quickly, and at the same time, due to the unstable voltage of the mains, the electronic tube and the lamp are easy to burn out, causing losses to the user. [0003] The new electronic tube has been improved in some parts. The circuit includes the AC-DC conversion circuit module, the useless band filter circuit module, the DC-AC inverter circuit module, and the output device. It can reduce vibration noise and control temperature rise, and quickl...
