3 Terms and definitions

The terms and definitions defined in GB/T 24826 and the following apply to this document. 3.1 Group Bin A defined range of LED performance characteristics consisting of LEDs with similar nominal performance such as chromaticity, photometric performance, radiation characteristics, and/or electrical performance It is defined by a group of LED chips or LED packages. [Source. GB/T 24826-2016, 3.5] 3.2 grid An area defined by a series of grid points and represented by color coordinates. 3.3 Gridpoint The color coordinates in u',v' color space (or equivalently x,y color space) are determined by two independent indices. The first index p is the number of steps counted along the Planck locus and its extension toward the blue line crossing the high temperature boundary; the second index j is counted along the Judd isotherm Count the number of steps. Note. The u', v' color space is specified in ISO /CIE11664-5, and the x, y color space is specified in ISO /CIE11664-1. 3.4 white groupwhitecolourbin A quadrilateral region defined by 4 grid points. ......
