  • 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.

  • Patent number: 10531536
    Abstract: An optoelectronic assembly and method for operating an optoelectronic assembly are provided. In some aspects, the optoelectronic assembly includes an organic light-emitting component, a temperature sensor configured to record a temperature value, and a driver circuit coupled to the organic light-emitting component and the temperature sensor. The driver circuit is configured to apply an AC voltage to the organic light-emitting component when the organic light-emitting component is switched on, and if the recorded temperature value is less than a predetermined temperature threshold value, where the AC voltage is, at least, temporarily less than an instantaneous threshold voltage of the organic light-emitting component. The driver circuit is also configured to apply a DC voltage to the organic light-emitting component if a measurement value is greater than or equal to a predetermined threshold value, where the DC voltage is greater than the instantaneous threshold voltage of the organic light-emitting component.

  • Publication number: 20180220509
    Abstract: An optoelectronic assembly and method for operating an optoelectronic assembly are provided herein. The optoelectronic assembly may include an organic light-emitting component, a temperature sensor for recording a temperature value, and a controller coupled to the organic light-emitting component and to the temperature sensor. The controller may be configured to apply an alternating current (AC) voltage to the organic light-emitting component when the organic light-emitting component is switched on, and if the recorded temperature value is less than a predetermined temperature threshold value, where the AC voltage may, at least, temporarily less than an instantaneous threshold voltage of the organic light-emitting component.
