Sunlight/surround lighting the integrated transducer that is used for the control of air conditioning for automobiles and light
Technical field
The utility model relates to a kind of sensor, particularly a kind of sunlight/surround lighting integrated transducer that is used for air conditioning for automobiles and light control.
Background technology
At present, the operating mode of air conditioner for automobile machine is same as indoor air conditioner more, is locked in the running parameter of artificial setting.Owing to during running car, often be subjected to open-air light to wait condition influence, to the regulation and control of vehicle interior temperature, still be not so good as people's will like this.Though " a kind of light controlling device that is used for On-vehicle air conditioner " patented product by name emerges, and has been applied to regulate vehicle interior temperature automatically in the high-grade automobile, and its positive effect is arranged, its function singleness, and cost performance is higher.
In addition, along with the extension and the development of automobile industry optical, mechanical and electronic integration, people also expect to be used for automobile lamp and instrument background light source, also can realize the auto-control function, alleviate driver's working strength with energy savings.
The utility model content
The purpose of this utility model just is to overcome the deficiency of above-mentioned prior art, provides a kind of simple in structure, has the sunlight/surround lighting integrated transducer that is used for air conditioning for automobiles and light control of two light control functionality.
In order to achieve the above object, the technical solution adopted in the utility model is:
A kind of sunlight/surround lighting integrated transducer that is used for air conditioning for automobiles and light control comprises: cover cap, surround lighting Sensitive Apparatus, sunlight Sensitive Apparatus, circuit module, housing base and I/O interface.It is characterized in that:
Described circuit module is a two-sided printed board, and the left side, printed board top is equipped with the surround lighting Sensitive Apparatus, the right is equipped with the sunlight Sensitive Apparatus, in the printed board, the below is separately installed with other electronic devices and components in ambient light sensor circuit and the sunlight sensor circuit, the entire circuit module is installed in the housing base, its lower end is connected with the I/O interface, constitutes an integral body.
Sunlight sensor in the utility model, it is the photoelectric sensor that the outer intensity of illumination of car is converted to current signal.When intensity of illumination outside the car increased, the resistance of photoelectric sensor just descended, and the induction current of generation just increases, and the pulse signal of output just broadens; Otherwise, as the same.Air conditioning condition just changes with it in the car, to keep vehicle interior temperature equilibrium, amenity.
Ambient light sensor in the utility model, the same sunlight sensor of its mechanism, be mainly used in the control of automobile lamp and instrument background light source, according to from the current signal of ambient light sensor visibility size with environment-identification, make car inner control system open or regulate car light and instrument background light intensity automatically, so that illumination, energy savings effectively to be provided.
Distinguishing feature of the present utility model is: two combine into one with sunlight sensor and ambient light sensor, concentrates on one, realized the optical, mechanical and electronic integration function; Have simple in structure, volume is little, function is many, reliable operation, characteristics such as easy to use.
