  • Publication number: 20240049373
    Abstract: An optoelectronic module includes a control element, at least one temperature sensor, and at least one semiconductor emitter unit. The semiconductor emitter unit includes at least a first emitter and a second emitter. The first emitter is intended to emit electromagnetic radiation in a first wavelength range. The second emitter is intended to emit electromagnetic radiation in a second wavelength range different from the first wavelength range. The control element includes a memory unit and a driver output for each emitter. The temperature sensor determines a temperature. Each emitter is assigned a non-linear characteristic curve in the memory unit. The control element is intended to drive the emitters independently of each other by means of a respective driver output. The control element controls the emitters depending on the determined temperature and the respective characteristic curve of the emitter.

  • Patent number: 11388798
    Abstract: 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.

  • Publication number: 20220126749
    Abstract: 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.
