Problems solved by technology
However, most of these triangular red warning signs are pasted with red reflective film, which can only emit light passively, because the brightness of the reflection is very limited, so when encountering insufficient brightness of car lights at night, or encountering dusk, or encountering rainy weather , its actual warning effect will be greatly reduced
If the triangular warning light is made of red light with constant brightness, the warning effect is not eye-catching enough.

The invention relates to an automobile-fault red LED shining triangular warning lamp. The automobile-fault red LED shining triangular warning lamp is characterized by comprising a 12-V lithium battery, an oscillating circuit and sound production circuit and an ultra-brightness red light-emitting-diode display circuit; the oscillating circuit and sound production circuit is composed of an oscillator IC1, a timing capacitor C1, an adaptive resistor R1 and a loudspeaker SY, and the model of the oscillator IC1 is LM3909. Only one timing capacitor is arranged on the periphery of the LM3909 to form a shining circuit, and can directly drive the shining warning triangular lamp and the loud speaker to work at the same time. The circuits have the advantages of being high integration degree, stable in shining frequency, resistant to vibration, stable in running and the like. According to the automobile-fault red LED shining triangular warning lamp, as ultra-brightness red light emitting diodes are installed on the three sides of a triangle, noticeable shinning red light is emitted at night, and the warning effect much better than that of single red light without changes is achieved.
Description
technical field [0001] The invention belongs to the technical field of automobile electronics, and relates to a red LED flashing triangular warning light for automobile failure. Background technique [0002] When a vehicle breaks down on an urban road, especially on an expressway, in order to ensure road safety, in order to prevent rear-end collisions, a triangular red warning symbol is usually placed tens of meters behind the car to remind the rear to approach in the same direction Vehicles. However, most of these triangular red warning signs are pasted with red reflective film, which can only emit light passively, because the brightness of the reflection is very limited, so when encountering insufficient brightness of car lights at night, or encountering dusk, or encountering rainy weather , its actual warning effect will be greatly reduced. If the triangular warning light is made of red light with constant brightness, its warning effect is not eye-catching enough. [0...
