Abstract

The invention discloses a fluorescent lamp with a short circuit protection circuit; a camera display and a bus are included; the fluorescent lamp is formed by setters, a central controller, a driver monitor, and door side displays; the front door and back door of the bus are respectively provided with the setter and the door side display; the central controller and the driver monitor are added with an electron tube; the central controller processes received information, sends the information to the door side displays and the driver monitor, and the driver uses the camera display to inform passengers to get off or control vehicle motions; the setter is provided with at least more than two buttons; a luminescence electron tube and an inductor are arranged in the button; the central controller is provided with a device combining digits with stations; the information can be sent to the door side displays and diver monitor; the door side display is provided with an LCD; the driver monitor is provided with a digit device, so passengers and the driver can communicate through the device. The fluorescent lamp is simple in structure, easy to use, and low in cost.

Description

technical field [0001] The invention relates to a fluorescent lamp with a short-circuit protection circuit, in particular to a fluorescent lamp with a short-circuit protection circuit used in a fluorescent lamp. 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....
