21、rt of IEC 62707 specifies general requirements, a grid and a corresponding code for the colour binning of white LED packages emitting incoherent, visible radiation. It applies for LED packages. Other parts of the IEC 62707 series covering chromaticity of coloured LED packages, luminous flux/luminous
22、 intensity, colour rendering and forward voltage are in preparation or under consideration. NOTE 1 This International Standard does not apply for LED modules, LED lamps and LED luminaires. NOTE 2 Even though the words “white light“ are used, the purpose of this International Standard is not to defin
23、e “white light“, but to specify a grid and a corresponding colour code for the colour binning of white LED packages emitting incoherent, visible radiation. The area covered by the grid may differ from the definition of white light given in other standards or regulations. 2 Normative references The f

29、stant steps along the Planckian locus, and its extension beyond the high temperature boundary towards blue colours, in the first direction (Planck-axis) and in equidistant steps along the Judd isothermal lines in the second direction (Judd-axis). The origin of the grid shall be on the Planckian locu
30、s at T(u/v) = (0,180 06/0,395 28). The distance between adjacent grid points along the Planckian locus and its extension beyond the high temperature boundary towards blue colours and along Judd isothermal lines in the u, v colour space shall be s = 0,001 74. Steps along the Planckian locus are count
31、ed with a positive index p, steps toward blue with a negative index p. Steps towards the saturated colour line (gamut) along the Judd-axis are counted with a positive index j and with negative index j in the opposite direction. NOTE 1 s = 0,0017 4 has been chosen as providing for the best alignment
32、with existing chromaticity requirements. The Planckian locus shall be extended beyond T(towards blue) as follows (see Figure 1): Quadratic Bzier locus defined by three points: P1: T(u/v) = (0,180 06/0,395 28) P2: (u/v) = (0,141 22/0,155 93) P3: (u/v) = (0,256 80/0,016 59) The Bzier locus is B(t) = P
33、1 (1-t)2+ 2P2 t (1-t) + P3 t2; t (0;1). NOTE 2 P2is the intersection of spectral locus of the u, v colour space and tangent of Planckian locus at Tin direction of blue wavelength. NOTE 3 P3corresponds to a wavelength of 380 nm on the spectral locus of the u, v colour space. BS EN 62707-1:201462707-1

Figure 1 Extension of the Planckian
35、locus beyond TThe coordinates uBB(p) and vBB(p) of the grid points on the Planckian locus (BB = Black Body) and the extension on the Planckian locus are given in Annex A and Annex B, as well as the unit increments uBB(p) and vBB(p) of the corresponding Judd isothermal lines. The u and v coordinates
36、of a grid point specified by the indices p and j are given by u(p, j) = uBB(p) + j uBB(p) v(p, j) = vBB(p) + j vBB(p) or u, v (p, j) = (uBB(p) + j uBB(p); vBB(p) + j vBB(p) The index (p, j) = (0, 0) corresponds to the Tpoint and the coordinates are (rounded to five digits): u (0, 0) = 0,180 06, v (0
37、, 0) = 0,395 28 or u, v (0, 0) = (0,180 06; 0,395 28) Grid points in the u, v coordinate system can be translated into equivalent grid points in the x, y coordinate system using the following equations: x(p, j) = 9u(p, j)/(6u(p, j) 16v(p, j) + 12) BS EN 62707-1:2014 8 62707-1 IEC:2013 y(p, j) = 4v(p
38、, j)/(6u(p, j) 16v(p, j) + 12) It is recommended to round grid point coordinates to 5 digits after the decimal sign. 4.2 White colour bins White colour bins are defined as the area inside a quadrilateral. An origin (p, j) and a positive step size m, n along the Planckian locus (or its extension beyo
39、nd T) and the Judd lines respectively is given. The quadrilateral is constructed by connecting the four grid points u, v (p, j), u, v (p+m, j), u, v (p, j+n) and u, v (p+m, j+n) or x, y (p, j), x, y (p+m, j), x, y (p, j+n) and x, y (p+m, j+n) It should be noted that white colour bins with step sizes
40、 of m or n equal 1 are not considered to be practical in view of measurement accuracy. 4.3 Code for the chromaticity of white LED packages 4.3.1 Optional six digit code for the designation of white colour bins Subclause 4.3.1 specifies an optional code for white colour bins using only six digits. Th
41、e first four digits are reserved for the identification of the grid point representing the origin of the white colour bin. The last two digits are reserved for the number of steps along the Planckian locus (or its extension beyond T) and the Judd lines respectively. The first digit is: “e” for p 0 a
42、nd j 0 “f” for p 0 and j 0 “g” for p 0 and j 0 “h” for p 0 and j 0 The second and third digits represent the absolute value of p starting at “aa“. Only the following letters shall be used in the counting for the second and third digit: a b c d e f g h j k l m n p r s t u v w x y z NOTE 1 The coding
43、for the second and third digit can also be found in the column “Code“ in Annex A (p 0), respectively in Annex B (p 0). The code for |p| is specified in Table 1.
