Foggy day brightened warning triangle

Abstract

The invention discloses a foggy day brightened warning triangle, comprising a first equilateral triangle frame, a second equilateral triangle frame, a base, first LED light emitting groups, second LEDlight emitting groups, spotlight covers, a first light transmissive casing, a second light transmissive casing, a rain mist sensor, a controller and an LED power supply, wherein the rain mist sensoris mounted on the top of the back surface of the first equilateral triangular frame; each side of the front surface of the first equilateral triangular frame is equipped with the first LED light emitting group; each side of the front surface of the second equilateral triangular frame is equipped with the second LED light emitting group; each second LED light emitting group is composed of a plurality of second LEDs; and the plurality of second LEDs are installed in the matching spotlight covers. The foggy day brightened warning triangle has a good light transmission effect in rainy days or foggy days, a good warning effect, and adjusts the brightness of the LEDs according to the concentration of the rain or fog.

Description

Technical field [0001] The invention belongs to the field of traffic warning signs, and in particular relates to a triangular electronic warning sign with increased brightness on foggy days. Background technique [0002] As a commonly used traffic warning sign, warning triangles are mainly used to place around vehicles when a car breaks down to warn passing vehicles and prevent collisions. Since various accidents of automobiles are sudden, it is necessary to put the warning triangle in the trunk of the car for emergencies. Most of the common warning triangles are a luminous body coated with reflective materials. Some triangle warning signs that rely on external light reflection have poor light transmission in the rain or fog, which directly affects the warning effect, so they are not suitable for use on highways. Patent CN200990180 discloses an electronic strobe triangle The warning signs use LED lights to strobe to provide warnings when driving. Although the warning effect of t...

Because various accidents of automobiles are sudden, it is necessary to put the warning triangle in the trunk of the car, so that it is needed in case of emergency. Most of the common warning triangles are a luminous body coated with reflective materials. Some triangular warning signs that rely on external light reflection have poor light transmission effect in rain or fog, which directly affects the warning effect, so they are especially not suitable for use on expressways, and a kind of electronic strobe triangle is disclosed in patent CN200990180 The warning sign uses LED lights to provide warnings for
