This is an RGB linear lighting project in the Teatro Mori theater in Chile. As this project, the RGB light strip is used as a design element, and the aluminum profile is used as a linear lighting fixture. Its installation method is surface fixed installation, mainly The effect of uniform lighting is presented through surface lighting, so the uniformity of lighting is required to be higher. The use of 4040 RGB 120LEDS/M high-density light strips can achieve uniform and no spot effects. Linear lamps installed on the surface as the main lighting are very Suitable, in addition to high density, there is also a 5mm ultra-narrow width option, which can be suitable for aluminum profiles of different sizes to achieve the effect of unlimited RGB and size.
