Problems solved by technology

It is impossible to adjust and change the artistic lighting scene to express content according to changes in the external environment (such as the audio input of an external MIC microphone)
In the existing technology, if scene control of LED lights is required, it is often operated through a remote control device, and the equipped remote control device can only realize several simple fixed scene modes, resulting in a poor actual operating experience.

Embodiment

[0027] See figure 1 , figure 1 It is a flow chart of a voice-activated lighting scene effect realization method in the present invention. figure 1 In the voice-activated lighting scene effect realization method shown, the audio information collected by the MIC microphone is used as the input information to refine and identify, and the volume of the sound data and the real-time dynamic information of the music rhythm are extracted, and then the microprocessor uses the PWM waveform In the form of LED light dimming signal, LED light color adjustment signal, LED light flicker frequency control signal, and then realize the stage scene effect control of the brightness, color and flicker frequency of the light.

[0028] Combine below figure 1 , taking the application on an LED lighting array as an example, an application embodiment of a method for implementing a sound-activated lighting scene effect is specifically described.

[0029] Step S1, the microphone collects voice data of...

Abstract

The invention discloses a voice-operated lighting scene effect realization method. The method includes that audio information collected by an MIC microphone is taken as input information for refining and identification, real-time dynamic information of volume and music rhythm of voice data is extracted, then an LED lamp dimming signal, an LED lamp color matching signal and an LED lamp flicker frequency control signal are outputted through a microprocessor in a PWM (pulse-width modulation) waveform, and further stage scene effect control on light brightness, color and flicker frequency is realized. Art lighting scenes shown by an LED light array is more intelligent and more obvious in interactivity, and the light array can show the art effect in a larger area range.

Description

technical field [0001] The invention relates to the technical field of lighting control, in particular to a method for realizing sound-activated lighting scene effects. Background technique [0002] With the development of computer technology, digital dimming technology gradually appeared and gradually replaced analog dimming technology, and then a variety of communication protocols in the form of digital transmission appeared one after another. In order to enable the consoles and dimmers produced by various manufacturers to be connected to each other, USITT (United State Institute for Theater Technology, American Stage Lighting Association) formulated in 1986 the data communication between consoles and dimmers. Protocol DMX512. After several revisions of the protocol, DMX512 has become a widely used lighting control protocol. [0003] At present, the demand for the control methods of household lamps or stage lights for entertainment venues is more focused on intelligence,...
