为了使指定色温的紧凑型荧光灯的色坐标落在CIE规定的标准色容差范围内(即“进圈”),还同时满足显色指数的要求,是很复杂的问题。除首先需按荧光粉三色间合理组配,达到适当的色坐标x、y值外,它还受樊光粉的比重、颗粒级配和制灯工艺等多种因素的制约。本工作在低色温区给出选定荧光粉的组配与色温等参数间的规律性 In order to make the color coordinates of a compact fluorescent lamp of a specified color temperature fall within the standard color tolerance (ie, “into a circle”) defined by the CIE and satisfy the requirement of a color rendering index at the same time, it is a complicated problem. In addition to the first need to press phosphor trigeminal rational allocation, to achieve the appropriate color coordinates x, y value, it is also Fan powder proportion, particle grading and lighting technology and other factors. The work in the low color temperature region gives the selected phosphor combination and color temperature and other parameters between the regularity
