[INLES2009] Xiao Hongqing: LED to improve the quality of T5 fluorescent lamp dimming control analysis

Taiwan University of science and Technology Professor Xiao Hongqing in the third international new light source and New Energy Forum (INLES 2009) on the topic of "to improve the quality of the T5 fluorescent lamp dimming quality control analysis," the report of LED.

Professor Xiao in the frequency and voltage of two dimming ballasts, fluorescent lamp will be placed on the integral ball according to a fixed proportion of light and light mixing, and optical measurement equipment to capture the relevant data, according to the color temperature (corrELated color, temperature, CCT), color (color rendering property) to do a series of analysis and spectrum distribution, put forward by the optical characteristics of dimming ballast type decision. Based on the changes of the optical properties of the above hybrid process, this paper discusses the method of calculating the distribution of the spectrum and the color rendering. And to develop a calculus for spectrum, determine the color index to improve the original number of lights each light LED, and optical measurement equipment verified, confirm the feasibility of this method, so as to shorten the day after the light on improving the time needed to.
