A long row of warning lights and its circuit

Abstract

The invention relates to a long row warning light and its circuit, comprising a lamp holder, a plurality of light source components and a fixing device. The lamp holder is provided with a card slot, and a plurality of sliders are arranged in the card slot, and the sliders can be opposed to each other in the card slot. The lamp holder slides, the light source assembly is installed between the two sliding blocks through the fixing plate, and the fixing devices are respectively installed at both ends of the lamp holder. The circuit of the present invention includes a voltage stabilizing circuit, a control circuit, a driving circuit and an LED lighting circuit. The control circuit is provided with a single-chip microcomputer (U1), and the control circuit is connected with a current limiting resistor (R1), a voltage stabilizing diode (ZD1), and a filter capacitor (C1). ), there are 14 pins on the microcontroller (U1). The invention has the characteristics of reasonable structure design, simple and stable installation, and convenient replacement or maintenance of the light source.

Description

technical field [0001] The invention relates to a vehicle lamp, in particular to a long row of warning lamps and a circuit thereof. Background technique [0002] Long rows of police lights are usually used in police cars, ambulances, and road law enforcement vehicles. [0003] The light source assembly of the existing long row of warning lights is usually installed on a fixed plate with the same length as the lamp holder as a whole, and then the fixed plate is inserted into the slot of the lamp holder after installation. It is easy to get stuck and difficult to install; and if you want to replace the light source after installation, you need to remove the entire light source assembly fixed on the fixing plate. After replacing the light source, install the entire fixing plate, which is also extremely troublesome . [0004] Moreover, conventional warning light equipment has a single function. In order to achieve different warning effects, it is necessary to install various w...

Problems solved by technology

[0005] In order to solve the above-mentioned technical problems, the present invention designs a long row of warning lights, which solves the problems of complicated installation and troublesome replacement and maintenance of the existing long row of warning lights for vehicles, and only needs 3 electric wires (positive pole of power supply / power supply) in terms of circuit design. Negative pole / control line), wide working voltage (DC9-30V), a power switch and a control button are set in the cab, and the functions that previously required multiple devices can be realized
