Description
Technical field
The present invention relates to the simple circuit of the light-operated time-delay control of a kind of direct current.
Background technology
At present, it is multiple to utilize light-operated circuit design scheme to have, and seldom has at light-operated delay control circuit, and some can be controlled but circuit structure complexity, element are more.
So, need a kind of new technical scheme to address the above problem.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides the simple circuit of the light-operated time-delay of a kind of direct current control, this circuit structure is simple, be easy to realize, by regulating the time that resistance value, capacitance are controlled time-delay.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
The simple circuit of the light-operated time-delay control of a kind of direct current comprises light-operated branch road, time-delay branch road, relay control load branch road; Described light-operated route diode D1, adjusting resistance R 1, light-sensitive element RG form, route diode D2, charging resistor R2 are propped up in described time-delay, charging capacitor C1, discharge resistance R3 form, and described relay control load props up route transistor Q, relay K, diode D3, thermistor R4, load composition.
With respect to prior art, the light-operated delay control circuit of the easy direct current of the present invention is simple in structure, be easy to realize.
Description of drawings
Fig. 1 is circuit theory diagrams of the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is done further explanation.
Be illustrated in figure 1 as the simple circuit of the light-operated time-delay control of a kind of direct current.Comprise light-operated branch road, time-delay branch road, relay control load branch road.Described light-operated route diode D1, adjusting resistance R 1, light-sensitive element RG form; The D1 rectification, the resistance of regulating R1 is regulated the voltage at R3 two ends.Route diode D2, charging resistor R2 are propped up in described time-delay, charging capacitor C1, discharge resistance R3 form; Constitute integrating circuit by charging resistor R2 and capacitor C 1; Can pass through the resistance of allotment charging resistor R2 and the appearance value of capacitor C 1, thereby regulate the charging interval; Charging interval is delay time.Described instantaneous discharge is propped up route diode D2, and discharge resistance R3 forms; Can pass through the resistance of allotment discharge resistance R3, thereby regulate discharge time.Described relay control load props up route transistor Q, relay K, diode D3, thermistor R4, load composition; When illumination, light-sensitive element RG resistance is very little, has big electric current to pass through, transistor Q conducting, and relay K gets electric adhesive, and its normally-closed contact disconnects, and load quits work.
The above only is preferred implementation of the present invention; be noted that for those skilled in the art; under the prerequisite that does not break away from the principle of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
