Description
Technical field
The utility model relates to the simple circuit that a kind of direct current light control time-delay is controlled.
Background technology
At present, utilize the design of light-operated circuit to have multiple, seldom have for light-operated delay control circuit, some can be controlled but circuit structure is complicated, element is more.
Therefore, need a kind of new technical scheme to address the above problem.
The utility model content
In order to overcome the deficiencies in the prior art, the simple circuit that the utility model provides a kind of direct current light control time-delay to control, this circuit structure is simple, be easy to realize, controls the time of time delay by adjusting resistance value, capacitance.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
The simple circuit that a kind of direct current light control time-delay is controlled, comprise light-operated branch road, time delay branch road, Control load branch; Described light-operated route diode D1, regulating resistance R1, 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 Control load branch is comprised of transistor Q, relay K, diode D3, thermistor R4, load.
With respect to prior art, the easy direct current light control time-delay of the utility model control circuit is simple in structure, be easy to realize.
The accompanying drawing explanation
Fig. 1 is circuit theory diagrams of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
Be illustrated in figure 1 the simple circuit that a kind of direct current light control time-delay is controlled.Comprise light-operated branch road, time delay branch road, Control load branch.Described light-operated route diode D1, regulating resistance R1, 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; Form 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 Control load branch is comprised of transistor Q, relay K, diode D3, thermistor R4, load; When illumination is arranged, light-sensitive element RG resistance is very little, has larger electric current to pass through, transistor Q conducting, and relay K obtains electric adhesive, and its normally-closed contact disconnects, and load quits work.
The above is only preferred implementation of the present utility model; be noted that for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
