Development of Rotating Crystal Kaleidoscope Disco Ball Light
Disco light ball, also known as ball mirror. Is a large sphere covered with many glass lenses or other reflective material. In clubs, entire disco balls are usually suspended above the dancers' heads. Once the spotlight is focused on the spinning ball, random bands of light are projected onto the walls, ceiling and floor.
A variable speed motor controlled by the DJ or lighting technician can change the speed and direction of the disco ball as it spins. The use of disco balls in dance club mirrored balls actually predates disco balls by decades.
In the mid-1960s, disco was introduced to the United States. It was only spread in some black clubs in New York at first. In the 1980s, since Leslie Cheung's song monica became popular in Hong Kong, disco music became popular in China.
From the perspective of music, disco is generally dominated by 4 or 4 beats, with a strong beat, and each beat is outstanding; its speed is about 120 beats per minute. Its structure is short, the lyrics are simple, and there are many repetitions of paragraphs. In fact, for all the tunes, just adjust the speed and change to a beat that stands out for each beat.
