Atmosphere illuminating system and method based on music contents

Abstract

The invention relates to an atmosphere illuminating system and method based on music contents. The system is composed of an atmosphere controller and an LED lamp strip; the atmosphere controller is provided with an analog audio input interface and an LED lamp strip control interface; music is played through a music player and then input into the atmosphere controller through the analog audio input interface; and the music controls the LED lamp strip through the atmosphere controller. The music is input into the atmosphere controller through the analog audio input interface; the atmosphere controller acquires an audio signal and converts the analog audio signal into a digital signal through a built-in AD converter, such that original music sampled waveform data is generated; the waveform data forms a time-domain acoustic wave signal; furthermore, a Fourier transform algorithm is carried out; and the time-domain acoustic wave signal is converted into a sound intensity signal in different frequency bands. When users enjoy the music or sing, the number of lamps or the intensity of the lamps can be changed in real time according to change of different frequencies of the music; and thus, the user experience is improved.

Description

technical field [0001] The invention relates to a lighting method, in particular to an ambient lighting system and method based on music content. Background technique [0002] With the development of LED technology, lighting has changed from monochrome to multi-color, which can present more content to users. Different colors bring users different moods and atmospheres. Different moods such as excitement and hesitation can use colors to deepen the atmosphere experience. However, the color change of lighting in the prior art requires manual control or automatic control according to a predetermined logic, and the color change cannot be implemented according to people's mood or preferences. For example, in some performance stages, according to the needs of the performance music, the brightness, color, and irradiation angle of the light are artificially preset at a specific time point when the specified track is played. Although the light and shadow effects complement each othe...

AI Technical Summary

Problems solved by technology

Although the light and shadow effects complement each other with the stage performance, it is still impossible for the lights to automatically match any song

Another example is the LED color-changing ambient light in KTV. The color change is in a fixed mode, and it cannot change automatically according to the rhythm of the song selected by the user.
