Intelligent warning triangle with automatically adjustable visibility

Abstract

The invention aims to overcome the defect that a traditional LED flashing warning triangle for use on an expressway is unable to automatically adjust LED flashing visibility and the traditional LED flashing warning triangle being poor in visibility in daytime and too dazzling in nighttime causes a great potential safety hazard to each vehicle coming behind at high speed, and aims to apply a photosensitivity control technique allowing automatic recognition of brightness on sunny days or cloudy days or at dusk or night, to the LED flashing warning triangle for the first time. In this case, the invention provides an intelligent warning triangle with automatically adjustable visibility; a constant-current constant-voltage boost module (2), a photosensitive resistor (3) and a control module (4) capable of automatically adjusting flashing brightness are added inside; in daytime sunlight, the triangle can give a high-visible red flashing triangular emergency warning signal to each vehicle behind 100 meters ahead; that is to say, a 100-meter safety distance is provided at each key moment.

Description

Technical field [0001] The present invention relates to road car failure triangular warning device, specifically, when a car accidentally breaks down (breaks down) or has an accident on the road, a farsighted triangular warning sign with LED flashing is placed on the road behind the car, belonging to the car Car spare in the field of vehicle failure triangle warning sign. Background technique [0002] When the car is driving on the expressway, once a tire blows out or other failures occur and it is forced to occupy the road and break down, a triangle warning sign with LED flashing is specially used to place on the road 50 meters behind the broken down car, but at present The traditional LED flashing triangle warning sign used on the highway has the biggest safety hazard: it cannot automatically adjust the brightness (eye-catching degree) of the LED flashing. If it is fixed at a suitable high brightness during the day, it will be super bright at night. , it will cause glare ...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the shortcomings of the traditional LED flashing triangle warning signs that cannot automatically adjust the eye-catching degree, the purpose of this invention is to apply the photosensitive control technology that can automatically identify the brightness of sunny days, cloudy days, cloudy days, dusk and night to the LED flashing triangle warning signs for the first time It can automatically supply different currents that are actually needed according to the brightness of various actual needs in sunny days, cloudy days, cloudy days, dusk and night, and can automatically adjust the eye-catching degree of the warning triangle flashing
