Abstract (en)
[origin: WO2009094976A1] A lighting device (1) for back-lighting a display is disclosed.The lighting device comprises: -at least one semiconductor element (3) which is suitable for generating electromagnetic radiation of a first wavelength range; -a first wavelength conversion material (30) which is located downstream of the radiation-emitting front side (6) of the semiconductor element (3) in the emission direction (8) thereof and which is suitable for conversion of radiation of the first wavelength range into radiation of a second wavelength range different from the first wavelength range, and; -a second wavelength conversion material (31) which is located downstream of the radiation-emitting front side (6) of the semiconductor element (3) in the emission direction (8) thereof and which is suitable for conversion of radiation of the first wavelength range into radiation of a third wavelength range different from the first and second wavelength range. In addition, a display is described with one such lighting device (1).
