Abstract

The utility model provides a light automatic controller for night meeting of automobiles, which is composed of a photometric circuit, a control circuit of far light, an automatic flashing circuit of high-beam headlights, a control circuit of low-beam headlights, a manual control section of low-beam headlights, an executive circuit of far light and an executive circuit of near light. When being illuminated, the photometric circuit outputs voltage signals to drive integrated blocks 101 and 102 to work to switch off the high-beam headlights and switch on the low-beam headlights. The light automatic controller for night meeting of automobiles works stably, saves power consumption and meets the requirements of night driving.

Description

Automatic controller for light of vehicle meet at night

The utility model belongs to car electrics

Stipulate according to traffic regulation, travel when night, the front has car to sail relatively, when 150 meters of two spacings, answering the change country beam is passing light, gets into an accident in order to avoid cause both sides' driving sight " the temporary transient disappearance ", if long-time night running, the labour intensity of artificial adjusting light is more much higher than the labour intensity of steering vehicle, like this, just gives to travel and has caused unnecessary accident factor.

For addressing the above problem, the utility model provides a kind of cars meeting at night light auto mat, by light measuring circuit instant and near light lamp control circuit etc., far away, low beam is carried out automatic guidance.

The utility model relates to a kind of cars meeting at night light auto mat, it is characterized in that: by light measuring circuit 2, and distance light control circuit 3, the country beam circuit 1 that glitters automatically, dipped beam control circuit 4 is manually controlled the dipped beam part, distance light executive circuit 5, dipped beam executive circuit 6 is formed.Conducting when the sidelight circuit is subjected to illumination, with voltage signal input ic IC1, its output end voltage is reduced, country beam puts out, IC 2 input ends are subjected to the control of IC 1 mouth current potential simultaneously, make mouth produce high potential, passing light is lighted, and the distance light control circuit that glitters automatically is made of multi-vibrator.Oscillator signal is by BG ₂BG is passed through in collecting electrode output ₃The self-opening of control country beam in the dipped beam driving process.

The utility model is used to improve the safety of nighttime meeting, alleviates the labour intensity of chaufeur, and it is simple that this auto mat has assembling, and it is convenient to debug, and circuit working stability is high, power consumptive province, characteristics such as long service life.

Below in conjunction with accompanying drawing the utility model is described in detail:

Figure one is schematic circuit diagram.

The 1-country beam control circuit 2-light measuring circuit 3-distance light control circuit 4-dipped beam control circuit 5-distance light executive circuit 6-dipped beam executive circuit that glitters automatically wherein.

Country beam glitters control circuit 1 automatically by R among the figure ₁, R ₂, R ₃, R ₄, C ₁, C ₂, BG ₁, BG ₂Form multi-vibrator, BG ₃Be the signal output pipe, light measuring circuit 2 is made of 30 U type photo-transistors, and the characteristics of ending when using its conducting when being subjected to illumination, the unglazed photograph are controlled other circuit, and distance light control circuit 3 is by IC 1, C ₃, BG ₄, R ₇Constitute, base application circuit when being a representative type, the distance light executive circuit is cut effect pipe and BG by two vmos ₆, BG ₇, BG ₅Constitute R ₅Be biasing resistor, dipped beam control circuit 4 is by IC 2, C ₄, BG ₅, R ₉Constituting, is a typical Shi Ji application circuit, is controlled by distance light control circuit output voltage, and dipped beam executive circuit 6 is cut effect pipe BG by two vmos ₈, BG ₉, R ₆Constitute R ₆It is biasing resistor.When unglazed the photograph, sidelight circuit 2 ends, IC1 ₂The pin current potential is low, the lsi internal circuit upset, and the mouth current potential raises, and country beam is lighted.While IC2 ₆Pin promptly obtains high potential from ic output, and the internal circuit upset makes mouth low, and passing light ends.Sidelight circuit 2 conductings when illumination is arranged, IC1 ₆Pin current potential height, the circuit upset, the mouth current potential reduces, and distance light ends, simultaneously IC2 ₂The pin current potential reduces, the upset of IC2 internal circuit, and the mouth current potential raises, and passing light is lighted, and the country beam pulse letter that control circuit 1 produces that glitters automatically passes through BG ₃, light country beam one time second every 2-2.5, to the supervision of distant object, country beam automatic control circuit component parameters is R in the circuit diagram 1 in travelling for dipped beam ₁5K Ω ₁R ₂43K Ω ₁BG ₃2APP, R ₃56K Ω, R ₄5K Ω ₁C10uf/16v, C ₂10uf/16v, BG ₁3 DG6, BG ₂3DG6; The sidelight circuit component is a 3QU type photo-transistor, and distance light control circuit element is IC1NE555C, BG ₄2APP, C ₃0.01uf, R ₇400K Ω; Distance light executive circuit element is cut the effect pipe by vmos and is constituted; BG ₆Adopt TOP25MOS, BG ₇Adopt TOP25MO5, R543K Ω; Dipped beam control circuit IC2 adopts VE555C, C ₄0.01, BG ₅Adopt 2APP, R ₈400K Ω; The dipped beam executive circuit constitutes BG for the vmos field effect ₈Adopt TOP15MO5, BG ₉Adopt TOP15MO5, R ₆43K Ω.
