  • Patent number: 8716729
    Abstract: A lighting device (1) comprises at least one element (2) emitting light which is at least in part visible, and at least one conversion medium (3), which converts at least part of the radiation emitted by the element (2) into radiation of another frequency. In addition, the lighting device (1) comprises at least one filter medium (4) which filters at least part of the radiation, and which is configured such that the quantity of the conversion medium (4) to be used is reduced for at least one predetermined color saturation and/or one predetermined hue. This means that, compared with a light source corresponding to the lighting device (1) apart from the filter medium (4), savings are made in conversion medium (3) while achieving the same color saturation or the same hue. Light of a predetermined color saturation or of a predetermined hue may be efficiently generated by such a lighting device (1) and the lighting device (1) may be inexpensively produced.

  • Publication number: 20110141716
    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.
