Lighting device
摘要:
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. In operation, it also has high light intensities and a long service life.
