Accompanying drawing explanation
Fig. 1 is circuit diagram of the present utility model.
Detailed description of the invention
In order to make the purpose of this utility model and advantage clearer, below in conjunction with embodiment, this utility model is entered
Row further describes.Should be appreciated that specific embodiment described herein, and need not only in order to explain this utility model
In limiting this utility model.
As it is shown in figure 1, this utility model embodiment provides warning circuit icy on road, including the first resistance R1-the tenth
One resistance R11, operational amplifier IC, electric capacity C and LED, 6 feet of operational amplifier IC connect the 11st resistance respectively
R11 one end, the 3rd resistance R3 one end；1 foot of operational amplifier IC meets a fixed end and the moved end of the second resistance R2, the second resistance R2
Another fixed end be connected to the 11st resistance R11 other end, 14 feet of operational amplifier IC, the 6th resistance by the first resistance R1
R6 one end；2 feet of operational amplifier IC connect the 3rd resistance R3 other end and 5 feet of operational amplifier IC by the 4th resistance R4；
3 feet of operational amplifier IC meet the 5th resistance R5 to electric capacity C positive pole, the 8th resistance R8 one end, the 7th resistance R7 one end, the 7th electricity
11 feet of resistance R7 another termination operational amplifier IC, the 8th resistance R8 another termination the 9th resistance R9 one end, the 6th resistance R6 is another
One end and 12 feet of operational amplifier IC；10 feet of the 9th resistance R9 another termination operational amplifier IC；The 4 of operational amplifier IC
Foot connects LED one end, the LED other end and the equal ground connection of electric capacity C negative pole by the tenth resistance R10；Institute
The operational amplifier IC stated uses LM3900 four-operational amplifier.
It should be noted that the second described resistance R2 is swept resistance.
Additionally, the 11st described resistance R11 is critesistor.
The circuit of this detailed description of the invention uses a critesistor and three parts of LM3900 four-operational amplifier IC；
When temperature is down to 36 °F, the flicker the most per second of (light emitting diode) LED light is once.When dropping to 32 °F at a temperature of when, flicker
Frequency is accelerated, and LED is the most shinny.Amplifier I by critesistor with standard network resistance ratio relatively, and is connected to homophase input.
This detailed description of the invention can carry out warning icy on road effectively, is reported to the police by LED flicker, reminds people
Drive with caution.
The above is only preferred implementation of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of without departing from this utility model principle, it is also possible to make some improvements and modifications, these improve and
