摘要:
A method for manufacturing at least one optoelectronic semiconductor device includes providing a substrate and applying a number of optoelectronic semiconductor chips, which are arranged spaced apart from one another in a lateral direction, on an upper face of the substrate. At least one reflective coating is applied to the exposed areas of the substrate and the lateral surfaces of the optoelectronic semiconductor chips. Openings are introduced into the reflective coating, which completely penetrate the reflective coating. Electrically conductive material is arranged on the reflective coating and at least on some parts of the openings. Radiation penetration surfaces of the optoelectronic semiconductor chips are free of the reflective coating and the reflective coating does not laterally extend beyond the optoelectronic semiconductor chips.
摘要:
An optoelectronic component comprising a housing and a luminescence diode chip arranged in the housing is specified, which component emits a useful radiation. The housing has a housing material which is transmissive to the useful radiation and which is admixed with radiation-absorbing particles in a targeted manner for setting a predetermined radiant intensity or luminous intensity of the emitted useful radiation. The radiation-absorbing particles reduce the radiant intensity or the luminous intensity by a defined value in a targeted manner in order thus to set a predetermined radiant intensity or luminous intensity for the component. A method for producing an optoelectronic component of this type is additionally disclosed.
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 colour 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 colour saturation or the same hue. Light of a predetermined colour 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.
