Description

Music lighting rhythm system and method

Technical field

The invention relates to the technical field of lighting devices, and in particular to a music lighting rhythm system and method.

Background technique

With the advancement of science and technology and the improvement of people's living standards, people's demand for quality life is beginning to rise. The invention of incandescent lamps is one of the important signs of human civilization from modern times to modern civilization. People use the light to dye the night into white. After entering the 21st century, people found that in addition to lighting, lighting also changed the atmosphere and rendered the atmosphere. Since then, various lighting systems aimed at rendering the atmosphere of the scene have begun to appear in the market. The original simple lighting has become colorful and beautiful. Among the various ambient light technologies, there is a kind of ambient light technology called light music rhythm technology that plays a very important influence on people's quality life. In this kind of lighting technology, the lighting of the lighting system generally changes regularly with the change of the background music. The change is not necessarily the change of brightness, but also the change of color. This technology is usually divided into two implementations, one is to play the role of rhythm lighting according to the change of voltage in the speaker of the audio power amplifier system to drive the light and dark changes of the light. The speaker is composed of an electromagnet, a coil, and a horn diaphragm. The greater the energy of the sound, the louder the sound, the more voltage is needed to drive the horn diaphragm. This lighting system uses this phenomenon of the speaker to move an extra circuit in the middle of the coil to the horn diaphragm to drive the light, and the light and dark changes of the light change with the intensity of the music. The other is to manually pre-program the lighting system according to the type of music, thereby controlling different lights to flash and change with the rhythm of the music. Such a system requires programmers to have a deep understanding of the songs that will be edited. These programmers need to write a special script for some common songs or melody and burn the script to the ROM of the rhythm system (read-only memory). Medium, then the system starts to drive the lighting system based on the data in the read-only memory.

In the music light rhythm technology based on the speaker, due to the simplicity of the implementation principle, the light can not achieve complex effects, and the rhythm of the music can only be simulated by the basic light and dark changes. This kind of music lighting rhythm technology can only match the rhythmic rock or pop music. If it is a classical symphony or a softer music, the performance will be degraded because the rhythm is not obvious. In addition, the technology can only achieve the rhythm of the rhythm, and the rhythm is only a part of the musical expression, but the more important melody can not be expressed, not only that, the technology is difficult to control through software, only suitable for simple scenes.

In the lighting rhythm technology based on pre-programming of single-chip microcomputer, there is a limitation of the scope of application due to the need to manually script the music effect in advance. Since human beings have a wide variety of music since ancient times, each person's interest in music is different. There may be a database with lighting control scripts associated with all music. The lighting rhythm system using this technology requires a lot of time and money.

Therefore, whether it is based on a speaker or a music and light rhythm technology based on single-chip microcomputer and programming, it is impossible to realize a highly expressive lighting effect efficiently and conveniently.
