    Abstract: PROBLEM TO BE SOLVED: To provide an LED device, for example an LED module, with the least possible deviation from a predetermined color locus. SOLUTION: The LED device is composed of a plurality of LEDs which have color loci specified by color coordinate values in a CIE color space, respectively; all color loci are formed by two isotemperature lines having predetermined color temperatures, blackbody loci, and one line assigned to the blackbody loci, or are in a region formed by the two isotemperature lines and two lines assigned to the blackbody loci; and the lines assigned to the blackbody loci have certain predetermined threshold deviations, respectively.

    Abstract: A CIE standard color space may be used. The color produced by the LED (6) is at or close to the white point (5) on the color space. The space may be marked with five Judd lines (1), corresponding to color temperatures of 3000, 4500, 5750, 7000 and 9500 degrees K. The Judd lines are crossed by seven lines of constant color saturation (3) ranging from Deltac = -30 SWE to Deltac = 30 SWE. A line (2) marks the characteristic of a Planck radiator in the CIE standard color space. There is a further line of constant color saturation (3a).

    Abstract: An illumination device (1) for backlighting a display is disclosed. The illumination device comprises: at least one semiconductor body (3), suitable for generating electromagnetic radiation of a first wavelength range, a first wavelength conversion substance (30), which is disposed downstream of the radiation-emitting front side (6) of the semiconductor body (3) in the emission direction (8) thereof and is suitable for converting radiation of the first wavelength range into radiation of a second wavelength range, which is different from the first wavelength range, and a second wavelength conversion substance (31), which is disposed downstream of the radiation-emitting front side (6) of the semiconductor body (3) in the emission direction (8) thereof and is suitable for converting radiation of the first wavelength range into radiation of a third wavelength range, which is different from the first and second wavelength ranges. A display comprising such an illumination device (1) is furthermore described.
