Abstract

To overcome the shortcomings of traditional single star simulators, a new single star simulator is designed to achieve multi-colour temperature and wide-magnitude-range output. Its colour temperature and magnitude do not affect each other and can be adjusted in real time. The basic principle is to mix a number of light rays of different narrow-band spectrums and intensities to control the whole intensity. The system’s overall structure, including the structure of the light source, the band intensity controller and the magnitude controller was designed. The assembly and testing were completed. The results show that the system can simulate numerous colour temperatures with a relative error less than ±0.10 and a simulated magnitude range of 0~+6.5 MI with an error less than ±0.3 MI. This flexibly operated system is stable and reliable. This research has already been used in related equipment with positive operational results, which serves as a reference for further studies..
