摘要： An optoelectronic device comprises a layer stack, which includes a carrier layer, a cover layer, and a first layer. The first layer is in particular an intermediate layer, arranged between the cover layer and the carrier layer. At least one electronic or optoelectronic element, in particular an optoelectronic light source, is arranged on the first layer and at least one layer of the layer stack and preferably all layers of the layer stack are at least partially transparent. The layer stack comprises at least one layer which comprises particles with a high thermal conductivity and/or at least one thermally conductive layer which is arranged between two adjacent layers of the layer stack.

摘要： A light emitting device includes a radiation source for the emission of electromagnetic radiation and a converter element on which the electromagnetic radiation impinges in a first surface region and which, excited by the impinged electromagnetic radiation, emits visible light into an environment in a second surface region which differs at least partially from the first surface region. The wavelength of the light emitted into the environment differs from the wavelength of the electromagnetic radiation impinged on the converter element. The converter element includes a luminous element including a textile with a converter material. The converter material due to excitation by the electromagnetic radiation with a first wavelength emits visible light with a second wavelength differing from the first wavelength. The radiation source realizes a background illumination for the converter element. The first surface region is formed by a side surface or a back surface of the converter element.

摘要： A method for operating an optoelectronic semiconductor device. The semiconductor device includes a first optoelectronic semiconductor chip for generating, for example, blue light, an optional second optoelectronic semiconductor chip for generating, for example, green light, and a third optoelectronic semiconductor chip for generating, for example, red light. The semiconductor device also includes a driver unit which supplies the semiconductor chips with current during operation. The third semiconductor chip is operated on the basis of a temperature-brightness characteristic curve stored in the driver unit. The temperature-brightness characteristic curve is configured for a minimum color location deviation over an intended operating temperature range, relative to at least one reference color location.
