Accompanying drawing explanation
Accompanying drawing is the structure principle chart of a kind of Wireless Light modulating fluorescent lamp of the utility model system.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
As shown in the figure, a kind of Wireless Light modulating fluorescent lamp of the utility model system is comprised of power supply, transformation voltage stabilizing circuit, zero cross detection circuit, single-chip microcomputer, bidirectional triode thyristor drive circuit, bidirectional triode thyristor, daylight lamp circuit, wireless sending module and wireless receiving module.
What power acquisition was used is the alternating current of 220V~50Hz; The direct current that transformation voltage stabilizing circuit becomes 5V by the alternating current of the 220V~50Hz of input is powered to single-chip microcomputer.
The zero cross detection circuit course of work is as follows: zero cross detection circuit is mainly comprised of two opto-coupler chips and Schmidt trigger, first AC power is sent into two optocouplers, the input of noting two optocouplers is reverse, while making alternating voltage zero-crossing like this, no matter from positive voltage, become negative voltage or become positive voltage from negative voltage, can obtain at optocoupler output the step signal of a forward, after Schmidt trigger shaping, be also oppositely input on single-chip microcomputer external interrupt 0 pin, as interrupt trigger signal, single-chip microcomputer is signal judgement zero crossing thus, within a signal period, there are two zero crossings, phase difference between two zero crossings is 180 degree.
Each zero crossing at alternating voltage, by zero cross detection circuit, to outside middle-end 0 pin of single-chip microcomputer, send interrupt signal, single-chip microcomputer obtains the starting point signal of control cycle, control bidirectional triode thyristor turn-offs, and starts timer, and phase place is now made as 0 degree, after regularly finishing, timer just changes the driving signal of the control port of bidirectional triode thyristor, open bidirectional triode thyristor, now corresponding phase place is exactly the angle of flow of bidirectional triode thyristor, and visible angle of flow excursion is 0~180 degree.In the one-period of sinusoidal signal, only having like this bidirectional triode thyristor in specific time interval is conducting, also only have these times to have electric current to flow through fluorescent lamp, in one-period, the ON time of bidirectional triode thyristor is different like this, the power of fluorescent lamp will be different, thereby brightness is different, the utility model utilizes this principle to regulate fluorescent lamp brightness exactly.
After turning on light at every turn, single-chip microcomputer electrification reset, single-chip microcomputer is controlled bidirectional triode thyristor conducting with the angle of flow of acquiescence, and the angle of flow of this acquiescence can go to arrange as required.
Wireless sending module adopts the Infrared remote controller of two buttons, a button is the key that highlights, a button is to weaken brightness key, while having button to press on wireless sending module, the signal that single-chip microcomputer receives wireless receiving module is identified, and judgement is which button is pressed, when judging the key that highlights, press next time, with regard to controlling the angle of flow of bidirectional triode thyristor, reduce Δ θ, when judging, weaken brightness key and press next time, the angle of flow of just controlling bidirectional triode thyristor increases Δ θ, this increment Delta θ arranges as required, note being greater than 180 while spending when the angle of flow is increased to, the angle of flow will keep 180 degree constant, when being reduced to, the angle of flow is less than 0 while spending, the angle of flow will keep 0 degree constant.During bidirectional triode thyristor conducting, just have electric current to flow through fluorescent lamp, when bidirectional triode thyristor turn-offs, no current flows through fluorescent lamp, and while changing like this angle of flow of bidirectional triode thyristor, the power of fluorescent lamp changes, and the brightness of fluorescent lamp changes.
