Abstract
The utility model relates to an illumination control device comprising an illumination intensity detection circuit, a control circuit, an alarm circuit and an illuminating lamp drive circuit. An output signal of the illumination intensity detection circuit is transmitted to the control circuit and an output signal of the control circuit is sent to the alarm circuit and the illuminating lamp drive circuit. The illumination control device does not work at daytime, enables a lamp to give out light automatically if the illumination is weak, can be used for illumination devices in classrooms of schools or factories, has the function of sound and light prompt, and achieves the effects of energy conservation and environmental protection.
Description
Technical field
The utility model relates to a kind of control appliance, particularly be a kind of illumination control device.
Background technology
Traditional illuminator, be all round-the-clock lighting, and having namely wastes electric energy and accelerate again the shortcomings such as life-span of luminous tube.
The utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of illumination control device is provided.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of illumination control device, formed by illuminance testing circuit, control circuit, warning circuit and illuminating lamp driving circuit, the output signal of described illuminance testing circuit is transferred to control circuit, and the output signal of described control circuit is sent to respectively warning circuit and illuminating lamp driving circuit.
Described illuminance testing circuit consists of photo-resistor RG, variable resistance RP, the resistor R1 of mutual series connection, and the output of described photo-resistor RG is connected to ungated integrated circuit IC1 through resistance R 1.
Described control circuit consists of time-base integrated circuit IC2 and peripheral resistor R3-R5, diode VD1, VD2 and capacitor C1, the C2 that connects thereof.
By adopting above-mentioned technical scheme, the beneficial effects of the utility model are: the utility model is not worked by day, automatically lights when illumination is weak, can be used for classroom or industrial light equipment, has sound-light prompting function, reaches the energy-saving and environmental protection texts.
Description of drawings
Fig. 1 is frame structure schematic diagram of the present utility model.
Fig. 2 is circuit theory diagrams of the present utility model.
Embodiment
Further illustrate the utility model below in conjunction with the drawings and specific embodiments.
As shown in Figure 1 and Figure 2, a kind of illumination control device of the present utility model, formed by illuminance testing circuit 1, control circuit 2, warning circuit 3 and illuminating lamp driving circuit 4, the output signal of described illuminance testing circuit 1 is transferred to control circuit 2, and the output signal of described control circuit 2 is sent to respectively warning circuit 3 and illuminating lamp driving circuit 4.
Described illuminance testing circuit 1 consists of photo-resistor RG, variable resistance RP, the resistor R1 of mutual series connection, the output of described photo-resistor RG is connected to ungated integrated circuit IC1 through resistance R 1, and described control circuit 2 consists of time-base integrated circuit IC2 and peripheral resistor R3-R5, diode VD1, VD2 and capacitor C1, the C2 that connects thereof.
Daylight is stronger, photo-resistor RG is subjected to irradiation and is low resistive state, the input of ungated integrated circuit IC1 is low level, output is high level, diode VD1 conducting, and the 2nd pin of time-base integrated circuit IC2 and the 6th pin are high potential, the 3rd pin output low level of time-base integrated circuit IC2, information ring device BL does not send chimes of doom, not adhesive of relay K, and illuminating lamp EL does not work.
When light dies down, the resistance of photo-resistor RG also starts to increase, along with dying down gradually of light, the input terminal voltage of ungated integrated circuit IC1 also rises gradually, when this voltage rose to the threshold voltage of ungated integrated circuit IC1, its output became low level, made diode VD1 cut-off, capacitor C1 starts charging, and the 2nd pin voltage of time-base integrated circuit IC2 is descended gradually.Basis set became the 2nd pin voltage of IC circuit 2 to be down to 1/3 o'clock of supply voltage at that time, the 3rd pin output high level of time-base integrated circuit IC2, make the relay K adhesive, its normally opened contact is connected, illuminating lamp EL energising is lighted, another road is through resistance R 5 current limlitings, and information ring device BL obtains the electric alarm sound that sends, and reaches the energy-saving and environmental protection texts.
Above-described is only a preferred embodiment of the present utility model, can not limit the scope that the utility model is implemented, and every equalization of doing according to the utility model claim changes and decorates, and all should still belong in the scope that the utility model contains.
