摘要： A method of operating an optoelectronic component for generating a target brightness includes measuring a voltage across the optoelectronic component at one or more predetermined currents and receiving a target brightness for the optoelectronic component during a time period. The method also includes determining a pulse duration to operate the optoelectronic component during the time period based on the target brightness and subdividing the pulse duration into a number of partial pulse durations. The method further includes determining partial brightnesses from the measured voltages, which are compared with the respective brightnesses, and partial currents for operating the optoelectronic component are selected on the basis of the comparison. The method additionally includes operating the optoelectronic component during each partial pulse duration with the selected partial current. The partial currents of at least two partial pulse durations are different. The partial currents can each be assigned a voltage via the optoelectronic component.

摘要： A smart lamp system and method for monitoring a status of LEDs. The system can provide LED status monitoring using a logic controller communicating with at least one strip of LEDs. The system can utilize the logic controller to assign a unique identifier (ID) to the at least one strip of LEDs based on a physical position of a plurality of dual-inline package (DIP) switches incorporated within a smart lamp housing. The system can provide a hardware architecture to interface the logic controller with a power-line communication (PLC) transceiver. The system can establish a communication protocol between the PLC transceiver and a PLC receiver to efficiently communicate the statuses of the LEDs. The logic controller can generate a payload including a binary representation of the unique ID of the smart lamp and the statuses of the LEDs and transmit the payload to the PLC transceiver.

摘要： Solid state transducers with state detection, and associated systems and methods are disclosed. A solid state transducer system may include a support substrate that carries a solid state emitter and a state device. The solid state emitter and the state device may be stacked along a common axis. Further, the state device may be positioned to detect a state of the solid state emitter and/or an electrical path of which the solid state emitter forms a part. The solid state emitter may include a first semiconductor component, a second semiconductor component, and an active region between the first and second semiconductor components. The state device may include a state-sensing component having a composition different than that of the active region and the first and second semiconductor components. In some embodiments, the state-sensing component may include an electrostatic discharge protection device, a thermal sensor, a photosensor, or a combination thereof.

摘要： A lighting system (100; 120) comprises at least one lamp (10) and a processing unit (20) for estimating an end-of-life of the at least one lamp (10). The processing unit (20) is configured to receive a lamp burning time during which the at least one lamp is turned on and a forecasted temperature over a selected period of time at a location of the at least one lamp. The processing unit (20) is configured to estimate the end of life of the at least one lamp based on the lamp burning time and the forecasted temperature. By using the forecasted temperature, use of dedicated lamp sensors measuring internal parameters of the lamp usable for the end-of-life estimate may be avoided and the estimate may be simplified.

摘要： The invention relates to a short-circuit fault detection illumination device (1) for a motor vehicle headlight, comprising



a voltage input (SE) and a terminal (ME) for connection to earth potential,
a power branch (LS) supplied via the voltage input (SE), which comprises a number of light sources (2) to be monitored, wherein this number is at least two, wherein the light sources (2) are designed to emit the light of the illumination device (1) and the light sources (2) are connected to one another in series within the power branch (LS),

wherein the illumination device (1) further

has an auxiliary branch (HS) with transistors (3) arranged therein and connected to one another in series, wherein each light source (2) of the power branch (LS) is associated with one of the transistors (3), and thus a monitoring pair (P1, P2, P3, P4), consisting of a light source (2) to be monitored and a transistor (3) assigned for monitoring, is formed, wherein each transistor (3) is coupled to the cathode and anode of the light source (2) in such a manner that the voltage that drops across the light source (2) in normal operation is used to connect the transistor (3), and in the event of a short circuit of the light source (2), the voltage drop caused by the short circuit leads to a blocking of the transistor (3) and thus of the auxiliary branch (HS), wherein the short-circuit fault detection illumination device (1) further has a fault detection device (6) coupled to the auxiliary branch (HS), which is designed to output an error signal (SF) or trigger an error routine (FR) in the event of the auxiliary branch being blocked.
