Specific implementation mode
For technology contents, structure feature, realization principle and the objects and the effects of the utility model are described in detail, with
Lower combination embodiment simultaneously coordinates attached drawing to be explained in detail.
The utility model discloses a kind of classroom lighting automatic control systems, as depicted in figs. 1 and 2, including several lamps and lanterns
Group 1, several brightness sensors 2, several control switches 3, several light modulators 4 and controller 5.Several lamps and lanterns groups 1 are distributed on religion
Interior, each lamps and lanterns group 1 include several lamps and lanterns 10, and lamps and lanterns 10 include light source 100 and fan-shaped hood 101, hood 101 it is interior
Wall is provided with reflective layer (not shown), so that the light that light source 100 is sent out projects downwards as much as possible.Several brightness sensors
2 are separately mounted to the outer wall of the hood 101 of several lamps and lanterns 10 at top, and the light to reduce lamps and lanterns 10 passes brightness
The influence of sensor 2.Each control switch 3 is connected on respectively between each lamps and lanterns group 1 and power supply, each control switch 3 is controlled
Lamps and lanterns 10 in one lamps and lanterns group 1 of system open and close simultaneously.Several light modulators 4 are connected in series with several lamps and lanterns groups 1 respectively, are used
In the brightness for adjusting each lamps and lanterns group 1 in real time according to the detected value of several brightness sensors 2, i.e. each light modulator 4 is used for
Adjust the brightness of all lamps and lanterns 10 in a lamps and lanterns group 1.Controller 5 and several light modulators 4, several brightness sensors 2 and
Several control switches 3 are electrically connected, and controller 5 is turned on and off several controls according to the detected value of several brightness sensors 2
Switch 3.
Referring to Fig. 1, in the present embodiment, it is grouped teaching indoor lamps and lanterns 10 according to each row, is divided into three groups, it is each
There are four lamps and lanterns 10 in group, there are three switch 3 is controlled, this three control switches 3 control the lamp in above-mentioned three groups of lamps and lanterns groups 1 respectively
The opening and closing of tool 10, correspondingly, light modulator 4 is also provided with three, each light modulator 4 respectively with each group in four lamps
10 series connection of tool, the brightness for regulating and controlling all lamps and lanterns 10 in lamps and lanterns group 1.The detection of 5 real-time detection light luminance sensor 2 of controller
Value enters the detected value average computation of all brightness sensors 2 if brightness sensor 2 is detected from classroom window
The available light in classroom is more sufficient, and the control control switch 3 of controller 5 is in the open state, so that lamps and lanterns 10 are disconnected with power supply
It opens, when brightness sensor 2 detects that the indoor light of religion is weaker, controller 5 gives control 3 one signal of switch so that control
It makes switch 3 to be closed, opens lamps and lanterns 10.In addition, the brightness for the available light that controller 5 is detected also according to brightness sensor 2
Value, the brightness that control light modulator 4 adjusts lamps and lanterns 10 specifically can preset brightness values different from available light in the controller 5
10 luminous power of corresponding lamps and lanterns, to accomplish adjust automatically.Since the utility model is grouped lamps and lanterns 10, controller 5
In the detected value that detection light luminance sensor 2 is fed back, carried out as unit of group, if detecting a wherein lamps and lanterns group 1
The natural light brightness value of region is insufficient, and the natural light brightness value in other two groups is more sufficient, then controller 5 knows control
That group of lamps and lanterns 10 for opening insufficient light, in addition, controller 5 is adjusted in real time also according to the practical available light in each lamps and lanterns group 1
The brightness value of whole each lamps and lanterns group 1 to accomplish compartmentalization control, effectively save electric energy, and is convenient for management.Preferably, this
