Description
technical field [0001] The invention relates to the field of LED lighting control, in particular to an intelligent LED lighting control system and control method based on a vector machine. Background technique [0002] Under the background of global energy shortage, light-emitting semiconductor elements (LEDs) have been fully promoted and applied. At present, there are many researches on LED lighting control systems at home and abroad, and LED lighting control technology has been applied to various fields. At present, the control of LED lighting is mainly to connect the lights to the local area network, communicate with smart terminals such as computers, and then send control commands with smart devices to control the lights on, off, and dimming lights. [0003] In Zhao Chen's "SOPC-Based Adaptive LED Lighting System", the system can take advantage of the characteristics of LEDs and use information such as the temperature and light intensity of the external environment to o...
