Smart Lighting with Autonomous Color Tunability

Smart lighting technologies are very important for high illumination quality and energy-efficiency. In this article, lighting performance controlled by color sensor module has been studied. With simplified system architecture and effective algorithm, the module can be used to obtain precise color and light characteristics for a target area, which can help to tune the specific color rendering property and the intensity of illuminance to an appropriate level automatically for different lighting scenarios. The balance between color preference and color fidelity can be achieved easily with suitable transformation program, and the illuminance information offers a route for governing lighting in high energy-efficiency.
