Triangular flickering warning lamp for car failures

Abstract

The invention provides a triangular flickering warning lamp for car failures.The triangular car fault flickering warning lamp for car failures is characterized by comprising a 12 V lithium battery, a blocking oscillator and a high-brightness red light-emitting diode driving circuit, wherein the selected model of a time-base circuit IC1 in the blocking oscillator is NE555.Most common triangular red warning signs are simply pasted with red reflecting films which only can emit light passively, and as the reflecting brightness is very limited, the actual warning effect of the common triangular red warning signs is seriously weakened under the conditions of low car lamp brightness or nightfall or rainy days.Thus, flickering high-brightness red light-emitting diodes are installed on the three sides of the triangular flickering warning lamp for car failures respectively and can emit striking flickering red light at night, the striking flickering red light has a far better warning effect compared with single invariable red light, and thus an ideal warning effect can be achieved in the daytime or at night.

Description

Technical field [0001] The invention belongs to the application field of electronic technology and relates to a triangular flashing warning light for car failure. Background technique [0002] When a car breaks down on urban roads, especially on highways, in order to ensure traffic safety, a triangular red warning symbol is usually placed tens of meters behind the car to remind the approaching vehicles to prevent rear-end collision. However, most of these triangular red warning signs are only pasted with red reflective film, which can only passively emit light. Because the brightness of the reflection is very limited, the actual warning is when the brightness of the car lights is insufficient at night, or at dusk, or on rainy days. The effect will be greatly reduced. If the triangular warning light is made of a fixed red light, the warning effect is also somewhat poor. [0003] For this reason, the car fault triangle flashing warning light of the present invention is equipped wit...

AI Technical Summary

Problems solved by technology

However, most of these triangular red warning signs are only pasted with red reflective film, which can only emit light passively. Because the brightness of the reflection is very limited, it is actually a warning sign at night when the brightness of the car lights is insufficient, or at dusk, or in cloudy and rainy days. The effect will be greatly reduced

If a triangular warning light is made with a fixed red light, the warning effect is not good enough.
