Title: Cheng Luo and RGB Lighting Control Innovation.
Introduction
Cheng Luo is an inventor associated with Zhangzhou, China, and Leedarson Lighting Co., Ltd. His patent work addresses the control of color in RGB lighting systems through calibrated duty-cycle calculations.
Latest Patents
The provided patent information lists one patent for Cheng Luo: “Method and Apparatus for Calculating Duty Cycle of Lighting, Terminal, and Storage Medium.” The invention determines relationships among chromaticity coordinates, luminous flux, and the input duty cycles of the red, green, and blue light paths. It calibrates nonlinear transformations using tristimulus values measured during full-current operation, first to calculate a duty-cycle value for luminous flux and then to calculate a value for chromaticity. The resulting duty-cycle value is used to control the displayed colors of the RGB light source. The record reports 1 patent.
Career Highlights
Luo’s listed invention focuses on improving how RGB lighting systems calculate and apply duty cycles to achieve desired color output. His work is associated with Leedarson Lighting Co., Ltd., a company in the lighting industry.
Collaborations
The provided information names Hao Chen and Junru Liu as Luo’s coworkers. It does not specify whether they collaborated with him on this patent.
Conclusion
Cheng Luo’s listed patent concerns calibrated duty-cycle control for RGB lighting, connecting mathematical transformations with the practical control of displayed color.
