Briefly narrate the principle of work of Dim Dimmer below.
Meeting becomes the light guide principle of work: when two cars during at a distance of 250m, photo-transistor E1 receives the distance light optical signal of the other side's vehicle and produces photocurrent, make N1 the 3rd pin obtain an electric signal, N1 the 1st pin is given N2 the 2nd pin with signal one tunnel, be lower than N2 the 3rd pin level, N2 the 1st pin low level, D1 the 6th pin is low level also, make D1 the 4th pin high level, D1 the 2nd pin is high level also.N1 the 1st pin is given N2 the 12nd pin with another road of signal, is higher than N2 the 13rd pin level, makes N2 the 14th pin high level, and D1 the 1st pin is high level also.Like this, also high level of D1 the 3rd pin low level, the 10th pin high level, the 12nd pin.The photocurrent of photo-transistor E1 makes N1 the 5th pin obtain an electric signal simultaneously, N1 the 7th pin high level, and N2 the 6th pin is high level also, and is lower than the 5th pin level, makes N2 the 7th pin high level, and D1 the 13rd pin is high level also.D1 the 11st pin low level like this, N2 the 9th pin is low level, the 8th pin high level also, V14 conducting, D2 the 5th pin low level, V15 ends, the 8V power supply charges to C15 by R64R65, makes D3 the 3rd pin low level, and V18 ends, the 8V power supply makes the V21 conducting by R69V29R72, V22 ends, and K1 discharges, and head light is in the dipped beam state.If the other side's vehicle is used distance light always, N2 the 6th pin level is higher than the 5th pin level, N2 the 7th pin low level, D1 the 11st pin high level, N2 the 9th pin high level and greater than the 10th pin, N2 the 8th pin low level, V7 ends, V14 also ends, last K1 adhesive, and head light is in high-beam condition.Under the situation that vehicle front is unglazed, N1 the 1st pin low level, N2 the 12nd pin level is lower than the 13rd pin, N2 the 14th pin low level, D1 the 3rd pin high level, the 10th pin low level, the 11st pin high level, K1 adhesive as a result, head light is in high-beam condition.
Turn to and become the light guide principle of work: press left steering switch S 3-1, V8V13, R52R53R55 and C8 make the V14 conducting, and K1 discharges, and head light is in the dipped beam state.Press right steering switch S 3-2 too.
Overtake other vehicles and become the light guide principle of work: press the switch S 4 of overtaking other vehicles, when Der Blink und Abblendschalter output high level, by R59, the one tunnel charges to C12 through V10, makes N2 the 9th pin high level by R61 and V6 again, N2 the 8th pin low level, and V7 ends.Another road makes through V11 that V13 ends, the V14 conducting, and K1 discharges, and head light is in the dipped beam state.When the Der Blink und Abblendschalter output low level, V14 ends, the K1 adhesive, and head light is in high-beam condition.Along with the height variation of Der Blink und Abblendschalter outgoing level, head light far light and near light alternate.
In meeting, the three kinds of mode of operations that turn to, overtake other vehicles, the override of overtaking other vehicles.After the switch S of promptly overtaking other vehicles 4 pressed down, meeting became light and turns to change light not work.Turn to be better than meeting, after promptly pole changer S3 pressed down, meeting became light and does not work.
Obviously, the present invention turns to and head light also can automatic beam change when overtaking other vehicles except having nighttime meeting head light automatic beam change function, and obstacle overcome ability is stronger, is beneficial to safe driving, alleviate tired driver, can be widely used in all kinds of self-propelled vehiclees.
