[0007] Aiming at the influence of different lighting conditions on learning in the existing classroom lighting, the purpose of the present invention is to provide a scene-type classroom intelligent lighting system, a control device and an optimization and control method. The color temperature and illuminance of each test point under different driving current combinations of the dimming lamp group, and the dimming lighting distribution table is established. When it is applied online, the current activity mode in the classroom is identified based on the classroom image and human sensor signals, such as self-study, projection, blackboard teaching, Discussions, breaks, etc., according to the characteristics of different activities, adjust the light color scoring function of color temperature and illuminance. The driving current value of the LED string is optimized, and the optimization result is sent to the driver to change the light output of the lamp group to realize intelligent lighting suitable for various learning activities in the classroom

Abstract

The invention provides a scene-type classroom intelligent lighting system, a control device and an optimization and control method. The host unit obtains the color temperature and illuminance values, scene images and human body of each area of ​​the classroom based on the light color sensing unit, image acquisition unit and human body detection unit respectively. The position signal, based on the trained scene detector, identifies the current lighting scene according to the image characteristics and personnel position characteristics, and establishes the dimming lighting distribution table and the light color scoring function to control various combinations of LED string drive currents in the dimmable lamp group. Evaluation is carried out, and the combination of driving current values ​​is optimized through a multi-objective optimization algorithm, and finally the optimization result is sent to the driver for dimming. The light color scoring function of the present invention can be adjusted according to different learning activity scenes in the classroom, so that the optimized lighting conditions can meet the requirements of different learning scenes such as self-study, projection, discussion, breaks, etc., and the lighting control is improved. Sex, providing a more humane lighting environment for classroom learning.

Description

technical field [0001] The patent of the invention belongs to the field of intelligent lighting, and specifically relates to a scene-type classroom intelligent lighting system, a control device and a control method. Background technique [0002] The school is a place for learning. The lighting should fully consider the sufficient illumination required for reading and writing. It is necessary to choose a suitable light source and design and / or combine a comfortable and natural lighting environment. The classroom is the place where students spend the longest time every day. Inappropriate lighting not only affects students' learning, but may also cause students to be short-sighted. In the past, the lighting in the classroom was generally only required to be bright enough and not easily damaged. Today, with the progress of society and the development of lighting technology, meeting lighting standards is already the minimum requirement for classroom lighting, and further conside...
