Detailed description of the invention

Provide specific embodiment below in conjunction with accompanying drawing, further illustrate how this utility model realizes。

The indoor intelligent LED illumination System of a kind of unified with nature light as shown in Figure 1, system adopts modularized design, it is divided into two large divisions: LED controls end and electrically driven curtain end, LED controls end and mainly includes controlling module I, bluetooth module, NRF24L01 module I, infrared receiving module, LED drive module, illumination detection module I, infrared detection module, power module I, crystal oscillator module I, memory module, LED, control module I respectively with bluetooth module, NRF24L01 module I, infrared receiving module, LED drive module, illumination detection module I, infrared detection module, power module I, crystal oscillator module I, memory module connects, described LED drive module is also connected with LED；Electrically driven curtain end mainly includes controlling module ii, NRF24L01 module ii, illumination detection module II, power module II, crystal oscillator module II, electro-motor, curtain, controlling module ii to be connected with NRF24L01 module ii, illumination detection module II, electro-motor, power module II, crystal oscillator module II respectively, described electro-motor is connected with curtain。

By with the smart mobile phone of Bluetooth function or IR remote controller, sending relevant light and regulate signal。This signal can be transferred to control module I after receiving this signal by the bluetooth module (or infrared receiving module) of LED control end, and microcontroller according to the data type received, can start relevant light-modulating mode: general modfel or perseverance optical mode。

In permanent optical mode adjustment process, by intensity of illumination outside optical sensor module ii sensing chamber, when less than set illumination threshold value, electro-motor does not work, and on the contrary, this enters window shaping modes, and the adjustment flow process of concrete electrically driven curtain is as shown in Figure 2

In permanent optical mode adjustment process, when electrically driven curtain adjustment nature light can not meet demand, system will start indoor LED lamp perseverance light and regulate。CPU can increase the dutycycle of the output square wave of certain value every time so that LED drive module output voltage increases, and LED luminance increases, and then reduces on the contrary。Through dynamically regulating so that indoor illumination intensity is finally near the brightness to regulate。Concrete LED controls end program circuit as shown in Figure 3。

Permanent optical mode regulates program flow diagram as shown in Figure 4, and regulative mode is as follows: during optical sensor module detection environment illumination intensity, first compares with the illumination threshold value set, draws the signal needing to regulate。Namely when data more than (less than) setting value time, (increase) PWM duty cycle can be reduced, again gather Lighting information discriminatory analysis, if data be also greater than (less than) threshold value, repeat above operation, until illumination intensity value reaches (or close) to setting threshold value, then intensity of illumination is detected again, when the threshold range of data with setting coincide, system enters bottom state of cycle operation, otherwise it is put into light-modulating mode (this process is important, and system program is without this part, and LED module luminescence can be unstable)。When LED is in opening, illumination detection module can detect in environment whether presence of people in real time, when can't detect infrared light supply, it is informed about controlling module I people already out, now control module I will pass through to change output PWM duty cycle (being now zero), control LED drive module and close LED。When realizing nobody in LED range of exposures, it is automatically switched off LED。
