Description
Technical field
the utility model relates to automobile equipment technical field, is specifically related to a kind of Der Scheinwerfer mit FernlichtAbblendlichtStandlicht automatic regulating system.
Background technology
automobile lamp is the important component part of automobile, and it provides illumination necessary in running car and instruction, and at present, the control of car bulb, generally still by the manually operated mode of driver; When surrounding environment brightness changes, driver needs manual to carry out switch or switching to light, and use very loaded down with trivial details, which increase the burden in driving procedure of driver, driving experience is not good.
Summary of the invention
for overcoming above-mentioned defect, namely the purpose of this utility model is to provide a kind of Der Scheinwerfer mit FernlichtAbblendlichtStandlicht automatic regulating system.
the purpose of this utility model is achieved through the following technical solutions:
the utility model is a kind of Der Scheinwerfer mit FernlichtAbblendlichtStandlicht automatic regulating system, comprising:
be fixedly installed on the ambient light sensor outside shield glass, described ambient light sensor is connected with the light automatic control circuit for controlling automobile lamp work, and described light automatic control circuit connects with automobile head headlight;
this light automatic control circuit comprises: surround lighting memory device, photo threshold memory device, comparator and meeting vehicle controller;
described surround lighting memory device is connected with ambient light sensor, for storing ambient light signal that this ambient light sensor collects;
described photo threshold memory device is for storing the first photo threshold and the second photo threshold;
described comparator connects with surround lighting memory device and photo threshold memory device respectively, for ambient light signal is compared with first, second photo threshold respectively, if ambient light signal is less than the first photo threshold, drive the work of automobile head headlight, and drive meeting vehicle controller; If ambient light signal is greater than the second photo threshold, automobile head headlight is driven not work;
described meeting vehicle controller is connected with described comparator and ambient light sensor respectively, and it is for judging whether the variable quantity of ambient light signal in the given time reaches predetermined value, if reach predetermined value, then reduces the operating power of automobile head headlight.
further, be provided with the linearity control circuit linearly changed for controlling car light operating power in described meeting vehicle controller, this linearity control circuit is connected between automobile lamp power supply and automobile lamp.
further, described light automatic control circuit is in series with hand signal master cock, described hand signal master cock is for controlling the on off state of light automatic control circuit.
the utility model brightness is environmentally carried out adjustment automatically to car bulb and is controlled, and driver does not need to divert one's attention for controlling light again, and reduce the work load of driver, driving experience is good.
Accompanying drawing explanation
for ease of illustrating, the utility model is described in detail by following preferred embodiment and accompanying drawing.
fig. 1 is integral structure schematic diagram of the present utility model;
fig. 2 is electrical block diagram of the present utility model.
Detailed description of the invention
in order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further described.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
refer to Fig. 1 and Fig. 2, Der Scheinwerfer mit FernlichtAbblendlichtStandlicht automatic regulating system of the present utility model, comprising:
be fixedly installed on the ambient light sensor 100 outside shield glass, described ambient light sensor 100 is connected with the light automatic control circuit 200 for controlling automobile lamp work, and described light automatic control circuit 200 connects with automobile head headlight 300;
this light automatic control circuit 200 comprises: surround lighting memory device 201, photo threshold memory device 202, comparator 203 and meeting vehicle controller 204;
described surround lighting memory device 201 is connected with ambient light sensor 100, for store this ambient light sensor 100 collect ambient light signal;
described photo threshold memory device 202 is for storing the first photo threshold and the second photo threshold;
described comparator 203 connects with surround lighting memory device 201 and photo threshold memory device 202 respectively, for ambient light signal is compared with first, second photo threshold respectively, if ambient light signal is less than the first photo threshold, drive automobile head headlight 300 to work, and drive meeting vehicle controller 204; If ambient light signal is greater than the second photo threshold, automobile head headlight 300 is driven not work; When ambient light signal is more weak and lower than first threshold, illustrate that surrounding environment is comparatively dark, need to throw light on, therefore need to drive automobile head headlight 300 to work, when ambient light signal is comparatively strong and higher than Second Threshold, illustrate that surrounding environment is brighter, do not need to throw light on, therefore automobile head headlight 300 cuts out;
described meeting vehicle controller 204 is connected with described comparator 203 and ambient light sensor 100 respectively, and it is for judging whether the variable quantity of ambient light signal in the given time reaches predetermined value, if reach predetermined value, then reduces the operating power of automobile head headlight 300; When at short notice, ambient light signal strengthens suddenly, illustrates that opposite has intense light source to irradiate, namely runs into the situation of meeting, therefore needs the operating power will reduce automobile head headlight 300.
further, be provided with the linearity control circuit linearly changed for controlling car light operating power in described meeting vehicle controller 204, this linearity control circuit is connected between automobile lamp power supply and automobile lamp; It can realize regulating without rank gradual change type of car bulb.
further, described light automatic control circuit 200 is in series with hand signal master cock, described hand signal master cock is for controlling the on off state of light automatic control circuit 200.When user needs to carry out Non-follow control, open hand signal master cock, light automatic control circuit 200 will be in off-state, and car bulb will not carry out auto-control.
the foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
