Background technology
With the fast-developing and social progress of national economy, education all receives publicity in the whole society and payes attention to, campus rule
Mould increases also with the quantity of educatee and constantly expands, and the quantity in classroom is also increased considerably, to make teachers and students have comfortably
Impart knowledge to students and academic environment, either the area in classroom, facility and illumination, school side has paid within one's power, all ten
The effort for dividing.
But due to the opening management mode of school, and the awareness of saving energy of crew is thin, and the classroom of school is on daytime
In the case that indoor illumination intensity is very high, still generally existing is turned on light operation phenomenon.Energy shortage is the 21 century new class that faces of the world
Topic, outside the new energy is found, how energy saving, increasing the benefit also just becomes the important topic of our researchs, so
How school also becomes a problem in the urgent need to address saving electric power energy.
But China's illumination intelligent level is integrally also relatively low, brightness adjustment control mode is applied to into classroom, ladder religion
Again cost is too high for room, it is difficult to receive, and up to the present, the light fixture in school instruction building have selected fluorescent lamp mostly, and brightness adjustment control is needed
Special dimming ballast is wanted, it is comparatively laborious, therefore, switch control rule is the major control mode of classroom's illumination.
In prior art, also without both switch control rule and Based Intelligent Control effectively can be combined and the low photograph of cost
Bright system.
The content of the invention
The technical problem to be solved is to overcome the deficiencies in the prior art, there is provided a kind of intelligent classroom lighting system
System, its circuit structure is simple, by the way that switch control rule and Based Intelligent Control are effectively combined, makes the present invention both can be with effectively save
Electric energy, but also with easy to operate, low cost, be easy to promote advantage.
The present invention is achieved through the following technical solutions：

DC voltage is rectified into through rectifier bridge, then relevant voltage value VCC, magnitude of voltage VCC conducts are obtained Jing after first resistor current limliting
The power supply of timer is connected with timer No. 8 pins, and timer and the 4th resistance, the second electric capacity constitute together it is monostable
State trigger, IGCT is controlled by above-mentioned monostable flipflop, for the break-make of control load, is then used to control in the present invention
The unlatching and extinguishing of lamp processed, concrete operating principle is：On well-lighted daytime, when light is irradiated to five resistance, the 5th
The resistance of resistance becomes very little, presses switch, and No. 2 pins of timer can not produce triggering negative pulse of the amplitude less than VCC/3,
Therefore No. 3 pins of timer can not be made to export high level and turn on it triggering IGCT, load does not work；Evening or indoor light
When not enough, the resistance of the 5th resistance becomes big, presses switch, and No. 2 pins of timer generate the low level arteries and veins less than VCC/3
Punching, so that No. 3 pins output high level of timer, it triggers the control pole of IGCT, makes turn on thyristors, and load is bright,
In advance by the 4th resistance of adjustment and the value of the second electric capacity, different timings can be set, after corresponding timing, lamp
Extinguish.Therefore, the present invention switch control rule and Based Intelligent Control are effectively combined, realize only at night or indoor light not
Switch is pressed when sufficient can just make that lamp is bright, and timing one is arrived, and lamp actively extinguishes, and such as need to open again, needs to press switch again, and
Also will not be bright even if well-lighted daytime presses switch lamp, the illumination needs of people had both been met, the wave of electric energy is reduced again
Take, so as to significantly more efficient electric energy has been saved；In addition, circuit structure of the present invention is simple, timer technique is ripe and low cost, property
Can be reliable, it is easy to operate, it is easy to promote.
Further, also including the first electric capacity, one end of the first electric capacity is grounded, the other end and first resistor of the first electric capacity
