Description
The present invention relates to a kind of control circuit device of car lighting lamp.
In the present prior art, institute's entrucking lamp all comprises country beam and passing light on the vehicles such as various trains, automobile, motor bike, open low beam when the car front has car or light strong, Kaiyuan City's lamp all will be selected for use by the chaufeur manual control in the time of a little less than positive no car of car or the light, frequent, the trouble of this operation, strengthened driver's work load, in case ignored lamp conversion low beam far away, then light straight thrust opposite car driver's eyes, cause body and mind uncomfortable, even cause the accident.Chinese patent 90206945.4 discloses a kind of " cars meeting at night light auto mat ", but the design plan of this patent is complicated, and reliability is low, and the cost height can not be applicable to the harsh environment of automobile.
The object of the present invention is to provide a kind of car light control setup that can select lamp far away or low beam according to extraneous light automatically for use, the present invention is simple in structure, dependable performance, and cost is low, can alleviate the work load of chaufeur, is applicable to various vehicles.
Technical scheme of the present invention is as follows: the present invention is made up of light measuring circuit, control circuit and executive circuit, and the electro-optical tubes PC of light measuring circuit and variable resistance VR and resistance R 1 are in series; Control circuit is made up of aerotron Q, magnet coil 14, magnetic reed switch 21, wherein the base stage of aerotron Q connects the end of electro-optical tubes PC, the emitter of aerotron Q connects an end of vehicle light power supply positive pole and coil 14, the other end of the collecting electrode wiring circle 14 of aerotron Q also connects a resistance R 2 between power cathode, coil 14 is on magnetic reed switch 21, but induction by current and one of closed magnetic reed switch 21 end connects power cathode, its other end connects the coil Ry of the relay J of executive circuit, the other end power connection positive pole of coil Ry.
Wherein control circuit connects light measuring circuit and executive circuit respectively, control circuit links to each other with vehicle light power supply again with executive circuit, the control of controlled circuit also realizes lamp far away or low beam is connected shinny executive circuit and connected lamp far away and low beam, but light measuring circuit comprises that the inspection vehicle front light is strong and weak and produces the photosensor of corresponding electric signal.The present invention is contained in Vehicular body front, when strong illumination or opposite meeting Kaiyuan City lamp are met in vehicle the place ahead when night running, detect the power of light by light measuring circuit, by control circuit control executive circuit, realization is automatically converted to out low beam immediately by original institute Kaiyuan City's lamp, waits behind the meeting or high light automatically replies later lamp illumination far away again immediately.
But the photosensor PC in the light measuring circuit of the present invention be contained in a front end opening with receive light, on every side in the shading sleeve of reflected light rays, realize directed photometry, promptly receive only the also irradiates light in inspection vehicle the place ahead, veiling glare around it is reflected by the shading sleeve, to prevent that veiling glare from disturbing, accurately detect the place ahead irradiates light, this shading sleeve is fixed on Vehicular body front.
The present invention can respond to ambient lighting light automatically and control selecting for use of lamp far away or low beam in real time, thereby alleviate the work load of chaufeur, keep the possibility of the suitable illuminating ray of car with the generation of minimizing accident, concrete structure of the present invention is simple, dependable performance, cost is low, is applicable to various vehicles, has fabulous application prospect.
The invention will be further described below in conjunction with accompanying drawing.
Fig. 1 is a structured flowchart of the present invention;
Fig. 2 is the scheme of installation of photosensor in the light measuring circuit;
Fig. 3 is the cutaway view of Fig. 2;
Fig. 4 is schematic circuit diagram of the present invention;
Fig. 5 is the decomposing schematic representation of magnetic reed switch 21 and magnet coil 14.
Fig. 1 has reflected basic structure of the present invention.Photosensor PC in Fig. 2 and Fig. 3 is installed in the shading sleeve 11, this shading sleeve 11 can disturb veiling glare on every side 12 reflections to get rid of, and make photosensor PC receive only the chief ray 13 of the place ahead irradiation, chief ray 13 receives PC and the generation corresponding electric signal by shading sleeve 11 interior front space 16 as light sensing chamber.
In Fig. 4, light measuring circuit comprises electro-optical tubes PC, and PC and variable resistance VR and resistance R 1 are in series, and executive circuit comprises relay J, the normally closed point 33 of J and transit point 34 taps lamp far away and lamp far away, and the common contact 32 of J connects the vehicle light power supply positive pole; Control circuit is made up of aerotron Q, magnet coil 14, magnetic reed switch 21, wherein the base stage B of Q connects the end of VR, the emitter E of Q connects an end of vehicle light power supply positive pole and coil 14, the other end of the collecting electrode C wiring circle 14 of Q also connects a resistance R 2 between power cathode, coil 14 is on magnetic reed switch 21, but induction by current and one of closed magnetic reed switch 21 end connects power cathode, its other end connects the coil Ry of relay J, the other end power connection positive pole of coil Ry.Variable resistance VR can adjust the PC susceptibility of illuminating ray to external world by the adjustment of its resistance value.When certain intensity light is injected PC, the PC conducting, when the light of injecting PC failed to reach certain intensity, then PC was the off-state of ending.Magnetic reed switch 21 is that two conductive reeds are encapsulated in the glass, when the magnetic field that the magnet coil on magnetic reed switch 21 14 is produced by the electric current that is passed through reaches certain intensity, two reeds in the magnetic reed switch 21 are connected, when the magnetic field that coil 21 is produced did not reach certain intensity, two reeds of magnetic reed switch 21 separated disconnection.
When electro-optical tubes PC receives certain intensity light, PC conducting, then aerotron Q conducting, the current decay of coil 14 at this moment, the reed of magnetic reed switch 21 separates disconnection, and relay J produces action, the normally closed point 33 of relay J contact 32 together joins, and transit point 34 separates, and then the bright lamp far away of low beam puts out; When electro-optical tubes PC fails to receive certain intensity light, PC is by disconnecting, then aerotron Q ends, this moment, the electric current of coil 14 increased, the reed closure of magnetic reed switch 21 communicates, the relay J action, and the normally closed point 33 of relay J contact 32 together separates, transit point 34 contact 32 together joins, and the bright low beam of lamp then far away puts out.Electro-optical tubes PC is as photoswitch, and variable resistance VR regulates light receiving intensity and the wavelength of PC, generally mixes up when dispatching from the factory, and also can be adjusted according to its installation environment and environment for use with product of the present invention by the user.The power supply of vehicle light power supply V+ and V-supply entire circuit.
The present invention is that the ambient lighting degree is selected lamp far away or low beam automatically for use during according to night travel, and two Facing Movement vehicles meeting in a kilometer can be measured the car light light of the other side's car, then changes out low beam automatically and stimulates driver's eyes to avoid high light; The opposite does not have car or then selects lamp far away in the half-light district automatically for use.The present invention is suitable for various kinds of vehicles and railway transport vehicle, various automobile, lorry, motor bike, bicycle, battery-driven car, railcar, LPG Car and other vehicle.
