Preferably, described lighting apparatus comprises indoor illumination light fitting.
According to the utility model, by adopting controller in conjunction with technological means such as illumination detection, human body sensing, output controls, realized the Based Intelligent Control to lighting apparatus, solved thus that lighting energy consumption is high, inefficient problem.And device of the present utility model can also take full advantage of natural daylight, automatically regulates indoor illumination intensity.When guaranteeing necessary illumination, effectively reduced the operating time of light fixture, saved unnecessary energy spending, also extended the life-span of light fixture.
Description of drawings
For understanding better the utility model, hereinafter the utility model is described in further detail by reference to the accompanying drawings with embodiment.In accompanying drawing:
Fig. 1 is the structured flowchart of energy saver of the self-control lighting equipment of the utility model one embodiment;
Fig. 2 is the exemplary hardware circuit diagram of this embodiment middle controller;
Fig. 3 is the software program flow chart of this embodiment.
Embodiment
With reference to Fig. 1, Fig. 1 is the structured flowchart of energy saver of the self-control lighting equipment of the utility model one embodiment.Described device comprises lighting detecting circuit 11, body induction circuit 12, controller 13 and output control circuit 14.Wherein, controller 13 can adopt one chip microcomputer to realize, for example, adopts the AT89C51 single-chip microcomputer, and Fig. 2 is the hardware circuit diagram of this single-chip microcomputer.
Lighting detecting circuit 11 can adopt the optical sensor spares such as photodiode for detection of the ambient brightness of lighting apparatus, converts ambient brightness to corresponding digital level, then directly accesses the IO pin of single-chip microcomputer.As shown in Figure 2, when external environment illumination was strong, photo resistance R13 resistance was less, and the A level point is lower; When a little less than external environment illumination, photo resistance R13 resistance is larger, and the A level point is higher.This level signal is delivered to single-chip microcomputer, whether realize illumination by program control.
In the situation that the ambient brightness deficiency, the human-induced signal that controller 13 detects based on body induction circuit 12 controls lighting apparatus by output control circuit 14 and lights; If body induction circuit 12 does not detect the human-induced signal, controller 13 extinguishes by output control circuit 14 control lighting apparatus.
Preferably, body induction circuit 12 comprises pyroelectric infrared sensor, signal processing circuit two parts.For example, signal processing circuit can adopt integrated circuit BIS0001, is equipped with the rpyroelectric infrared sniffer that pyroelectric infrared sensor and a small amount of outward element consist of passive type.Wherein, pyroelectric infrared sensor can detect with cordless the infrared ray of human body radiation, and is converted into voltage signal.Slow due to the signal intensity of pyroelectric infrared sensor output, amplitude is little (less than 1mV), can not directly be used as the control signal of illuminator, therefore, the output signal of transducer must be through the processing of signal processing circuit BIS0001, as carry out two-stage and amplify, so that converting to, the irregular waveform of sensor output signal is suitable for the digital signal that single-chip microcomputer is processed.
Referring again to Fig. 1, preferably, described device also comprises delay selection circuit 15, is used for making lighting apparatus to light by the time delays of setting.For example, delay selection circuit 15 can adopt timer, by reading external parameter, realizes the timing of different time.
The signal that single-chip microcomputer is exported lighting detecting circuit 11 and above-mentioned signal processing circuit detects, and its output control signal is by the P2.0 pin output of single-chip microcomputer, as shown in Figure 2.In indoor environment illumination strong or illumination is weak but indoor nobody the time, P2.0 pin output high level, triode V1 cut-off this moment, relay J 1 is not worked, the lighting apparatus that is connected on the 220V alternating current does not work.When weak and transducer detects the indoor people of having at indoor illumination, P2.0 pin output low level, triode V1 conducting this moment, relay J 1 work, the 220V alternating current is added on lighting apparatus by relay J 1, and lighting apparatus is normally lighted.
Here, output control circuit 14 adopts Control.Relay is a kind of when input variable (electricity, magnetic, sound, light, heat) when reaching certain value, and the automatic control device that great-jump-forward changes will occur output variable.The advantages such as this device has that action is fast, working stability, long service life, volume are little, the device such as be widely used in electric power protection, automation, motion, remote control, measurement and communicate by letter.According to the difference of structure, it can be divided into the models such as electromagnetic relay, temperature-sensitive dry-reed relay, solid-state relay, reed relay, optical relay.Because electromagnetic relay is simple and easy to use, on off state extremely easily judges, so the utility model preferably adopts electromagnetic relay to control.
Single-chip microcomputer of the present utility model can opening or cutting out by the Control lighting apparatus; Brightness detects to the lighting apparatus periphery by lighting detecting circuit; If luminance shortage, single-chip microcomputer simultaneously the detection signal treatment circuit whether collected the human body pyroelectricity transducing signal; According to having or not the human body pyroelectricity transducing signal, single-chip microcomputer can be controlled at once lighting apparatus and open or close again.
With reference to Fig. 3, Fig. 3 is the software program flow chart of this embodiment.The main task of software section is, completes the processing to the output signal of above-mentioned lighting detecting circuit, signal processing circuit.When illumination is stronger, continue the output state of lighting detecting circuit is detected.When illumination is weak, the output state of signal processing circuit is detected.If the indoor people of having detected, control that lighting apparatus is lighted and delay time by the time of setting.When the indoor people of having being detected again in delay time, then delay time by the time of setting; If detect in delay time indoor nobody the time, control that lighting apparatus extinguishes and again the output state of signal processing circuit detected.
Obviously, the utility model described here can have many variations, and this variation can not be thought and departs from spirit and scope of the present utility model.Therefore, the change that all it will be apparent to those skilled in the art is within all being included in the covering scope of appended claims.
