Abstract
The utility model relates to an interactive light control device, in particular to an interactive variable light controller for vehicle headlamps, which comprises a receiver, a transmitter and a switching control circuit and is characterized in that a microwave directional receiver is provided as the receiver and a microwave directional transmitter serves as the transmitter. The control circuit comprises a transmission control circuit, a receiving control circuit and a switching control circuit. The interactive variable light controller highly integrates circuits based on the technic proposal as above, improves circuit stability and immunity and is characterized in simple structure and mounting and operational convenience.
Description
One, technical field: the utility model relates to the interactive control setup of a light, particularly a kind of interactive Dim Dimmer that becomes light guide of automotive headlamp that is used for.
Two, background technology: the interactive light control device that becomes of automotive headlamp adopts the light-inductive mode to control far away, the near conversion of light mostly at present; in the practical application because vehicle is subjected to the interference in many extraneous signals source in the process of moving, through regular meeting the misoperation phenomenon appears.If adopt the complete interactive light mode that becomes to control, when the spacious highway section of some road or other did not need to become light, the complete interactive light that becomes was made troubles again.
Three, summary of the invention: the utility model is exactly the defective that exists in design at existing light variable controller, cause a large amount of appearance of the maloperation phenomenon in the use, the interactive Dim Dimmer of automotive headlamp of strong, the convenient use of a kind of antijamming capability, interactive manually combination is provided.
Realize that the technical scheme that above-mentioned purpose adopts comprises receptor, projector and conversion control circuit composition, it is characterized in that: receptor is the microwave directional receiver, projector is the microwave directional transmitter, and control circuit comprises countdown circuit, reception control circuit and conversion control circuit composition; Wherein countdown circuit is by diode D1, radio frequency choke L1, regulator block I capacitor C 1, radio frequency choke L3, diode D6 and capacitor C 1, capacitor C 3, capacitor C 5, capacitor C 7 connects the back and inserts microwave emitter F composition, reception control circuit is by diode D2, radio frequency choke L2, regulator block I capacitor C 2, radio frequency choke L4 and capacitor C 2, capacitor C 4, capacitor C 6, capacitor C 8, diode D3 connects the back and inserts microwave receiver SH composition, conversion control circuit is by aerotron T, relay J, diode D8, resistance R, capacitor C 9, after connecting to form, diode D7 inserts microwave receiver SH and microwave emitter F respectively, relay J control beam deflector switch K3, by contact relay J 1 and relay J 2 respectively with country beam YD, passing light relay J D connects, the positive pole of control circuit divides two-way contact K1 and K2, be connected with the diode D2 of reception control circuit and the diode D1 of countdown circuit respectively, contact K1 directly is connected with beam deflector switch K3 simultaneously, and contact K2 directly is connected with contact relay J 2 with passing light relay J D.At resistance R series connection adjustable resistance W; Reception, emission and conversion control circuit are made a wiring board and are fixed in the shell of a bell mouth shape, and the edge of shell is provided with screw, and opening part is fixed with plastic sealed board, to the wiring board capping.
Interactive Dim Dimmer after the employing technique scheme, circuit is simple, as long as a side becomes light, the other side's automatic beam change is realized the interactive light that becomes, owing to adopt microwave receiving and launch mode, improve the stability and the anti-interference resistance of circuit, and had characteristics simple in structure, easy to install.
Four, description of drawings:
Fig. 1 is schematic circuit diagram of the present utility model;
Fig. 2 is an appearance assumption diagram of the present utility model.
Five, the specific embodiment:
Contrast shown in Figure 1ly ,+B is the power lead of vehicle beam deflector switch K, by entering the Dim Dimmer control circuit after the K switch control.When K switch with after contact K1 is connected, contact K1 has positive voltage, one tunnel contact J1 and country beam YD through relay J connects, YD lights, another road connects the laggard microwave receptor SH of going into through diode D2, radio frequency choke L2, regulator block IC2, radio frequency choke L4 and capacitor C 2, capacitor C 4, capacitor C 6, capacitor C 8, diode D3, with stand-by.The conversion control circuit of being made up of aerotron T, relay J, diode D8, resistance R, adjustable resistance W, capacitor C 9, diode D7 simultaneously also is in electriferous state.At this moment, there is not the meeting signal to send as the opposite, the mouth output low level of receptor SH, D7, T connection is in the distance light connection location by working as.After microwave receiver SH received microwave number, the mouth of receptor SH became high level signal by low level, D3, T conducting simultaneously, and the J adhesive, contact J1 disconnects, and country beam is closed in contact J2 adhesive, and passing light is lighted, and finishes the interactive purpose that becomes light.
When meeting, the constant light of opposite vehicle, but manual unlocking K switch, K2 is connected with contact, passing light DJ lights, electric current connects the laggard microwave emitter F of going into via diode D1, radio frequency choke L1, regulator block IC1, radio frequency choke L3, diode D6 and capacitor C 1, capacitor C 3, capacitor C 5, capacitor C 7 simultaneously, and vehicle sends microwave signal to the opposite.After the other side's vehicle receives signal, become passing light automatically, process is the same.Initiatively become light side behind the meeting and manually recover country beam, the passive side recovers country beam automatically.
Contrast Fig. 2, Dim Dimmer wiring board 4 is installed in the shell 1 of bell mouth shape, goes out to be fixed with plastic sealed board 3 at opening, and shell 1 periphery is provided with screw 2, is fixed on the place ahead of vehicle by screw.
