Description

LED strobe warning device

technical field

The utility model relates to the field of road traffic signal warning lights, in particular to a red and blue LED strobe warning device.

Background technique

On road construction or expressways, some signal warning lights or traffic warning signs marked with red paint are usually set up. The main purpose is to provide a reminder for vehicles or pedestrians. The existing warning lights mainly have complex control circuits and large volume , and the warning effect is not obvious. And the traffic warning sign marked with a single red pigment is not eye-catching, especially for drivers or pedestrians who drive at night, it is easy to cause dangerous accidents.

Contents of the invention

In order to solve the above problems, the utility model provides an alternate flashing indicator board composed of a strobe controller and red and blue LED lights, which can not only reduce the occurrence of dangerous accidents, but also give pedestrians and vehicles a good warning in advance. A warning device.

The LED strobe warning device of the present utility model comprises a strobe control circuit composed of a 555 oscillating circuit, a D flip-flop and a MOS tube, a red and blue LED flash light composed of a red LED light and a blue LED light, and the strobe control circuit The output port is connected to the red and blue LED flashlight.

The beneficial effects of the LED signal warning device of the utility model are as follows: 1. The stroboscopic control circuit is placed in the box body, and the red and blue LED flashlights are embedded in one side of the box body, which is compact in structure and easy to install and operate; 2. The red and blue LED flashlights The board is embedded in the inner side of the box body, and a transparent glass plate is installed on the outside. The glass plate is sealed around the contact with the box body, which has good shock resistance, waterproof, and dustproof effects; After the red LED flashes twice, the blue LED flashes twice again, and the red and blue lights flash alternately and continuously, giving pedestrians and vehicles a good early warning. Flashing with red and blue LED lights is better than a single red warning effect.
