If it is determined that someone in the quadrant area, then sending to the lighting control module includes the information for illuminating space someone,
The Intelligent lightening device is controlled by the lighting control module to continue to illuminate；
If it is determined that in the quadrant area nobody, then to the lighting control module send illumination nobody information of space, by institute
Stating lighting control module control reduces the load current for flowing through the Intelligent lightening device, and controls and close after preset time period
The Intelligent lightening device.
8. the control method as described in one of preceding claims, which is characterized in that described to be unmatched according to gray average
Quadrant area information obtains the gray value of each pixel of quadrant area, further includes:
Described image processing module is extracted according to the gray value of each pixel and obtains being located at what gray average unmatched
Things profile in quadrant area, and judge whether the things is people.
9. the control method as described in one of preceding claims, which is characterized in that if described determine have in the quadrant area
People, further includes: judge whether the quadrant area is the most edge quadrant area for illuminating spatial gradation image,
If it is determined that the quadrant area is most edge quadrant area, then illumination space most edge is sent to the lighting control module
The information of quadrant area someone is sent from the lighting control module to the Intelligent lightening device close to the most edge quadrant area
The information of the most edge quadrant area someone；
If it is determined that the quadrant area is not most edge quadrant area, then by lighting control module region according to this quadrant
Gray average adjust automatically flows through the load current of the Intelligent lightening device.
10. the control method as described in one of preceding claims, which is characterized in that the lighting control module to close to this most
The Intelligent lightening device of edge quadrant area sends the information of the most edge quadrant area someone, further includes:
The Intelligent lightening device of the close most edge quadrant area receives the information of described most edge quadrant area someone
Afterwards, illumination is started according to the information automatically.
