  • Patent number: 11375594
    Abstract: A LED lighting circuit has a plurality of LED segments connected in series. A switching arrangement is used to selectively bypass at least one LED segment to implement a tapped linear driver approach. Degrading of a component in the LED lighting circuit is detected, so that a first TLD current modulation scheme is implemented when no such degrading is detected whereas a second current modulation scheme, different from the first current modulation scheme, is implemented to compensate for said degrading. Said degrading is leading to an increase in a turning on voltage of one LED segment, and compared to said first current modulation scheme, said second current modulation scheme has a higher voltage threshold at which said LED segment is switched. In this way, protection may be provided for circuit components and the light output may be maintained at the desired level in the event of component degrading, such as LED chip failure or contact resistance changes.

  • Patent number: 11368322
    Abstract: The present invention relates to a simple data transmission protocol and a data receiving device (10, 10?, 10?, 10??) for a power over Ethernet system (100?) using the simple data transmission protocol. The device (10, 10?, 10?, 10??) comprises a port and a simple logic unit. The port is configured for receiving power and data transmitted to the device (10, 10?, 10?, 10??) via an Ethernet connection (16?). The simple logic unit is configured to decode data encoded in a characteristic of one or more data packets received at the port. The data can be encoded in data packet length, data packet duration, number of data packets in a predetermined interval, and/or sequence of data packets. The simple data transmission protocol can reduce power consumption as in contrast to the Ethernet protocol MAC does not need to be decoded for information transfer. Hence only simple logic functions are required.

  • Patent number: 11363692
    Abstract: An electrical luminaire receives an AC supply as well as an auxiliary power supply. A power converter converts the AC power to supply a lighting element. A power factor associated with the AC supply is used as a control input for selecting an amount of power to be supplied from the two supplies. This enables the overall power factor to be controlled, for example to avoid financial penalties associated with the use of the AC supply with low power factor.
