Description of drawings
Fig. 1 is the structural representation that the utility model is responded to light modulating device automatically;
Fig. 2 is the circuit diagram that the utility model is responded to light modulating device automatically.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, the automatic induction light modulating device that the utility model provides comprises human body induction module, comprises a plurality of transducers, is used for surveying the variation of human body infrared spectrum, the output induced signal; Microprocessor, its input port is connected with the output of described transducer, is used for the output signal according to described its output port of actuated signal control of input; Light-adjusting module connects the output port of described microprocessor, is used for regulating the electric current of input light fixture.
When the people entered and remain in the induction range, this moment, the people can move in induction range, described transducer output high level, and when the people leaves induction range, the load of switch automatic delay function.Described switch has super low-power consumption, oneself power consumption＜0.00005W.Described transducer sensitivity is high, and reliability is strong.
When human body moved closer to described transducer, described microprocessor was according to the induced signal of described input, and output is so that the output signal that the electric current in the described light-adjusting module raises gradually; When human body during gradually away from described transducer, described microprocessor is according to the induced signal of input, and output is so that the output signal that the electric current in the described light-adjusting module reduces gradually.During transducer that this has just realized installing near the ad-hoc location in parlor or the toilet as the people, light fixture brightens gradually; When transducer that the people installs away from the ad-hoc location in parlor or the toilet, light fixture is dimmed gradually.Easy to use, light does not stimulate eyes.
More excellent, the delay time after the described transducer output low level is no more than 30 minutes.Further more excellent, the adjustable scope of delay time after the described transducer output low level is 0.3 second to 18 seconds.
Described transducer adopts wide voltage design, and input 4.5V-20VDC exports fixing 3.3V, also can input with output to be: 2.7-5V.
More excellent, described transducer has the induction blocking time, and in the time period after described transducer time-delay output low level, described transducer is not responded to.Thereby realize " induction output time " and " blocking time " both interval work, can be applicable to the interval detecting devices; But the various interference that produce in the establishment load handoff procedure simultaneously.Further more excellent, described induction blocking time is no more than 1 minute.
But described transducer can adopt continuous trigger and can not two kinds of triggering modes of continuous trigger.
As shown in Figure 2, described microprocessor adopts 8051 series monolithics, and there is external interrupt its inside, two programmable Timer/counters, the input/output port of more than 20 control able to programme; Can realize Based Intelligent Control by coding.
