Abstract

The utility model provides an automatic control device for automobile lights. The device comprises a controller, an external light intensity sensor and an illuminating circuit of automobile lamps, wherein the input wire of the controller is connected with the anode and the cathode of an automobile power supply respectively, a hand-operated switch is connected on the cathode wire of the input wireof the controller in series, and the output wire of the controller is connected with the outlet wires of an automobile front lamp hand-operated switch and an automobile clearance lamp hand-operated switch respectively. The device can turn on or off a front lamp and a clearance lamp of an automobile instantaneously according to the changes of an external light environment, so as to realize the automatic on/off function and to provide prompt and necessary lighting for safe driving when the automobile suddenly enters such complicated areas with insufficient lighting as tunnels, garages and heavily foggy places, or travels at night.

Description

The car bulb automatic control device

Technical field

The utility model relates to the automotive lighting field, relates in particular to a kind of car bulb automatic control device.

Background technology

Chaufeur drives to pass through a dark relatively environment, during as basement garage or tunnel, human eye needs the adaptation time about 3 ~ 10 seconds, during this period of time, eyes are in blind pasty state attitude substantially (though illuminating street lamp is arranged in the tunnel, but still can not compare with daylight), can not open moment as car bulb, the accident of many car crashes just probably can take place; When chaufeur rolls basement garage or tunnel by day away from, because of daytime imperceptible light whether open, forget closing vehicle lamp sometimes, wait that the storage battery electricity has consumed when finding, vehicle can not normally start, and can result in hand cramps.

Summary of the invention

Technical problem to be solved in the utility model provide a kind of can be according to the variation of running light environment, realize the car bulb automatic control device of self-opening or closing automobile headlight or lampet.For this reason, the utility model by the following technical solutions: it comprises the lighting circuit of controller, car UV light intensity sensor and car light; The input line of described controller is connected with the both positive and negative polarity of automobile power source respectively, the manual power switch of connecting on the negative line of the input line of described controller, the output line of described controller is connected with the output line of described automobile headlamp with the hand switch of lampet respectively.

The utility model indication controller is digital signal controller commonly used, and it can adopt microprocessor (micro controller system etc.), industrial control unit (ICU) or by the control apparatus commonly used with calculation function that control chip and other peripheral circuit, elements constituted.The headlight of the utility model indication is head light or passing light or the country beam that is commonly called as, or the assembly of passing light and country beam.The lampet of the utility model indication is meant parking light, taillight, registration mark light, dashboard lamp.

Owing to adopt the technical solution of the utility model, the utility model can be according to the variation of automobile external light environment, front lamp of vehicle and lampet are opened or closed to moment, realize its self-opening or close, for automobile enters tunnel, garage, thick fog district suddenly or at the bad complex region of light such as night, in time provides the necessary security vehicling lighting.

Description of drawings

Fig. 1 is the structure partial cutaway view of embodiment of the present utility model.

Fig. 2 is the control flow block diagram of the embodiment of the utility model control headlight and little light switch.

The specific embodiment

With reference to attached Fig. 1 and 2.The utility model comprises the lighting circuit of controller 1, car UV light intensity sensor 2 and car light, and described car UV light intensity sensor 2 is photosensors such as photodiode, photo-transistor, photoconductive cell; Described controller 1 is connected with the lighting circuit of car UV light intensity sensor 2 and car light, accepts the signal of car UV light intensity sensor 2, according to the switch of the strong and weak Control of Automobile headlight of car UV light, lampet.Like this, can make headlight according to car UV light condition automatic shutter to help safety traffic.Such as in travelling by day during access tunnel, timely automatic shutter headlight.In the control of controller, also can further set parameter selectively, to reach further function, such as headlight is carried out time-delay closing.Can make under the strong situation of extraneous light by setting in the enforcement, by manual automotive light switch control headlight and little light switch, under the situation a little less than the extraneous light, by controller control headlight and little light switch to controller.Carry out the explanation of control flow below in conjunction with Fig. 2.

In the time of a little less than the signal of the car UV light intensity sensor 2 that controller reads is light, close if the manual automotive light switch signal that controller reads is lampet, headlight, then the signal of controller output be lampet, headlight open and with this signal as opening signal storage automatically; If the manual automotive light switch signal that controller reads is that lampet, headlight are opened, then controller is made as lampet, headlight pass with current demand signal, and judge that whether last time signal in the memory device is for opening automatically, as denying, then the signal of controller output is that lampet, headlight are opened, in this way, then the signal of controller output is that lampet, headlight close.

The signal of the car UV light intensity sensor 2 that reads when controller is light when strong, closes if the manual automotive light switch signal that controller reads is lampet, headlight, and then the signal of controller output is that lampet, headlight close; If the manual automotive light switch signal that controller reads is that lampet, headlight are opened, then the signal of controller output be lampet, headlight open and with this signal as the non-automatic signal storage of opening.If the manual automotive light switch signal that controller reads is that lampet is opened, headlight closes, no matter then the signal of sensor 2 how, the signal of controller output be that lampet is opened, headlight closes and with this signal as the non-automatic signal storage of opening.

Described controller is connected with the positive and negative level of automobile power source respectively with input line 4 by input line 6; The negative line of the input line of described controller is promptly imported the manual power switch 3 of the described controller of series connection on the line 4, when this manual power switch is opened, and controller work; Otherwise controller is not then worked.After described controller was installed, the car bulb hand switch still can normally use.

The output line of described controller is connected with the output line 8 of the manual headlamp switch of lampet with the output line 7 of the vehicle manual headlamp switch of described automobile headlamp respectively.

Described controller inserts car engine ignition switch output line by input line 5, can obtain automotive engine and whether start the signal that enters mode of operation.

Described controller 1 is installed on operator's compartment inside, and concrete controller can firmly be installed on the inboard shelter of baffle plate, bearing circle below, and is attractive in appearance and make things convenient for wiring; Controller switches can be installed at an arbitrary position; When front glass the top was green or grey, car UV light intensity sensor 2 was installed on chaufeur dead ahead, Windshield the top; When front glass the top was clear, colorless, car UV light intensity sensor 2 was installed on directly over the back mirror, the Windshield the top.

The controller 1 that the utility model adopted all can adopt common junction circuit commonly used with being connected of sensor, detector, lighting circuit etc.
