Abstract

The invention discloses a driving device of the emotional control of LED light color and brightness change. Based on the association of three basic acoustic characteristic quantities of fundamental tone in voice, speaking speed or voice pause time and voice intensity with four emotion of calmness, happiness, sadness, anger, the acoustic characteristic quantities are extracted through a circuit and a CIE color system and an industrial HSL primary color ring are employed to carry out a special algorithm operation to drive the LED light color and brightness to change, and a purpose of the real-time and automatic brightness adjustment is realized. At the same time, the wireless remote control, wireless bus and communication technology, a microprocessor special algorithm, Bluetooth audio transmission technology and new technology of LED luminescent material are integrated in the device, an LED lamp driving control device with moodiness, individuation, romance, energy saving and environmental protection and 'mood-video' conversion is realized, and the perfect combination of energy saving, lighting, emotional catharsis and comfort and lighting art is realized.

Description

technical field [0001] The invention belongs to the field of LED lighting drive control. It is suitable for intelligent drive control of LED lighting, specifically a driving device for emotionally controlling the color and brightness of LED lighting. Background technique [0002] Pitch, speech rate, and sound intensity are important parameters in the emotional acoustic feature parameters, which have a strong correlation and regularity with people's emotions, and they are also popular research topics, and they are generally keen on the processing and analysis of sampled data. , if you completely rely on the characteristic signals obtained by data analysis to control the composite color and brightness changes of the 3-color LED, without a high-speed processor, the real-time effect is very poor. With the continuous development of LED lighting technology, in addition to the most basic purpose of lighting, it is possible for LED lighting to meet people's psychological and emotio...
