Problems solved by technology

[0002] Commonly used LED lighting systems are generally used in large squares, advertising billboards, or any applicable places, such as restaurants, venues, PUBs, concerts, etc. However, they are generally controlled by engineers with circuits; therefore, LED lighting The change of music failed to achieve synchronization with the music, and even advanced or delayed. In practical terms, the sound and light effects of the scene are not ideal.

Embodiment Construction

[0034] Such as figure 1 As shown, the method of the present invention is to directly control the color of the LED light with the change of the sound frequency; The control circuit 40, and an LED light driving circuit 50 etc. constitute; wherein:

[0035] The audio frequency bandpass filter 10 can first filter out signals other than the audio source when the audio source is input, and at the same time appropriately amplify the audio source signal to output to the level comparison circuit 20;

[0036] The level comparison circuit 20 can amplify the signal again, and turn the signal greater than the reference voltage into a square wave, so as to facilitate frequency counting by the digitally integrated main control circuit 30;

[0037] The micro-control circuit 40 is made up of CPU, RAM, ROM, etc., and a firmware (FIRMWARE) is stored in the ROM to control all actions of the CPU;

[0038] The digital integrated main control circuit 30 can calculate the square wave signal from th...

Abstract

This invention relates to a control method and device of a total colorful LED acousto-optical system. Utilizing a sound source performance to control LED light, to make the sound and light changing synchronously with entire excellent acousto-optical effect which is sometimes soft sometimes exciting, not only lovely and vivid but also very strong.

Description

technical field [0001] The invention relates to a control method and device for a full-color LED acousto-optic system, which can make LED lights and sound sources change synchronously, and have excellent overall acousto-optic effects. Background technique [0002] Commonly used LED lighting systems are generally used in large squares, advertising billboards, or any applicable places, such as restaurants, venues, PUBs, concerts, etc. However, they are generally controlled by engineers with circuits; therefore, LED lighting The change of music failed to achieve synchronization with the music, and even advanced or delayed. In practical terms, the sound and light effects of the scene are not ideal. Contents of the invention [0003] The main purpose of the present invention is to provide a control method and device for a full-color LED acousto-optic system, so that the LED light and the sound source can be changed synchronously, and have an excellent overall acousto-optic effe...
