Abstract
The utility model relates to an automatic dimming circuit of an ecological house, which consists of a power supply voltage (VCC), four resistors (R1 to R4), two thyristors (V1 to V2), a triode (Q), a capacitor (C), an output port (A) and an output port (B) which are connected together. The automatic dimming circuit of the ecological house has the beneficial effects that the brightness of a lamp can be weakened by adjusting the magnitude of conducting pins of the thyristors and thereby the goal of circuit protection can be achieved.
Description
Technical field
The utility model relates to circuit field, particularly a kind of circuit with an automatic light meter of ecological room.
Background technology
Ecological room design of Controller theory is that imitation meets human body more a good life, rest environment arise at the historic moment technology-imitation natural ecological environments such as application message electronics, the effect that can play beauty treatment, skin care, takes care of health.Be integrated into a control system with these more existing practical techniques and realize that whole system is divided three modules: air-conditioning control module, central controll block, human-computer interaction module, realize mutually by communication modes between three control modules between the information transmission.
But the circuit with an automatic light meter that always lacks so far, a kind of not only simple but also effective ecological room.
Summary of the invention
The utility model provides a kind of circuit with an automatic light meter of simple and effective ecological room in order to overcome the deficiency of above technology.
The utility model is realized by following measure:
A kind of circuit with an automatic light meter of ecological room, by a supply power voltage VCC, four resistance (R1-R4), two controllable silicons (V1-V2), triode Q, capacitor C, two delivery outlet A and B are formed by connecting:
Be connected photo resistance R1 between the base stage of supply power voltage VCC and triode Q, be connected resistance R 3 between the emitter of supply power voltage VCC and triode Q, cross-over connection resistance R successively 2 between the collector electrode of resistance R 2 and triode Q, capacitor C and resistance R 4, the end ground connection that resistance R 2 is connected with capacitor C, the end that resistance R 4 is connected with capacitor C also links to each other with the end of controllable silicon V1, the other end of controllable silicon V1 links to each other with the end of controllable silicon V2, and this end of controllable silicon V2 directly connects output port B, the other end of controllable silicon V2 be connected on the output port A after electric light EL connects.
The beneficial effects of the utility model are: circuit of the present utility model, by regulating the size of silicon controlled conducting pin, the brightness of regulating lamp will weaken, and reaches the protection purpose of circuit.
Above-mentioned explanation only is the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of specification, below preferred embodiment of the present utility model and conjunction with figs. describes in detail as after.Embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.
Description of drawings
Fig. 1 is the drive circuit schematic diagram with an automatic light meter in ecological room of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is made specific description.
A kind of circuit with an automatic light meter of ecological room, by a supply power voltage VCC, four resistance (R1-R4), two controllable silicons (V1-V2), triode Q, capacitor C, two delivery outlet A and B are formed by connecting:
Be connected photo resistance R1 between the base stage of supply power voltage VCC and triode Q, be connected resistance R 3 between the emitter of supply power voltage VCC and triode Q, cross-over connection resistance R successively 2 between the collector electrode of resistance R 2 and triode Q, capacitor C and resistance R 4, the end ground connection that resistance R 2 is connected with capacitor C, the end that resistance R 4 is connected with capacitor C also links to each other with the end of controllable silicon V1, the other end of controllable silicon V1 links to each other with the end of controllable silicon V2, and this end of controllable silicon V2 directly connects output port B, the other end of controllable silicon V2 be connected on the output port A after electric light EL connects.
The concrete mode of operation of circuit with an automatic light meter of the present utility model is as follows:
Photo resistance is used for detecting the intensity of illumination of lamp as detection probe.When intensity of illumination was not enough, the photo resistance resistance increased, and makes the base stage point potential drop of triode low, and collector current increases, and the charging interval of capacitor C 1 reduces, and made the Phase advance of trigger impulse, and silicon controlled conducting pin increases, and illumination brightness increases; When intensity of illumination was too high, silicon controlled conducting pin can diminish, and the brightness of lamp will weaken, and reached the protection purpose of circuit.
The foregoing description just is to allow the one of ordinary skilled in the art can understand content of the present utility model and enforcement according to this for technical conceive of the present utility model and characteristics being described, its objective is, can not limit protection range of the present utility model with this.The variation or the modification of every equivalence of having done according to the essence of the utility model content all should be encompassed in the protection range of the present utility model.
