Sammi Cheng's concert

Recently, Hong Kong singer Zheng Xiuwen’s concert kicked off at the Venetian Macao, with the reverberating sound filling the scene and the intoxicating stage lighting. How did the engineering team create such a gorgeous stage lighting effect? Today, I will show you the lighting project of Zheng Xiuwen’s concert.

The success of a concert depends on the stage lighting effect. In creating and adjusting the atmosphere of the scene, amazing stage lighting can stimulate the resonance of the scene that makes people never forget it.

The mood of the music determines the lighting effect. Stage lights convey the emotion of music through color, affecting the audience present. For example, in warm and passionate music, the lights usually use warm colors like red, yellow, etc., while in more subdued, euphemistic music, blue and cool colors can be used.

The rhythm of music determines the rhythm of the light.Play between a tune with a prelude, vice rhythm, melody, and other components, lighting should be divided into different parts, lights will be through the duration, intensity, color and category changes to reflect the length of notes, sound intensity, the change of pitch and timbre.

However, there is a variety of stage lights, like LED light strings, LED point lights, SMD spotlights, soft flex neon lamps, LED guardrail tubes, wall lights, pixel screens, high-power floodlights, and other LED digital lighting. In the face of such a wide category of lamps, how can the stage lights be reasonably controlled to show the ideal dynamic lighting effect?

LTECH applied its products to make the best interpretation of the Sammi Cheng concert stage, using the LTECH DMX - SPI decoder. The stage DMX512 digital signal is converted to an SPI (TTL) digital signal. Through the DMX512 control computer controller and built-in function call, the change mode, speed, etc., can be selected. With the DMX decoder model, using the control table to edit and control IC-driven LED lamps, it can control each channel of the LED lights, with a 0-100% dimming dynamic effect, creating a perfect fusion of performance stage lighting with the singer's performance.

The lighting of Zheng Xiuwen’s concert rises and falls with the musical atmosphere, thus transforming into the effect of changeable light and shadow. This not only gives the fans a great view but also makes the lighting control more convenient and accurate. Since its establishment in 2016, LTECH’s products have been used in various large and medium-sized stages, such as the CCTV Spring Festival Gala, the CCTV National Day Opera Concert, the Golden Film Festival, China's New Song Stage Engineering, providing high-quality products for stage performances, showcasing vibrant colors and dazzling dynamic effects.
