Methods and systems are described for replacing a lighting device in a wireless lighting device network. A first lighting device is identified using a mobile device such as, for example, a smart phone. Configuration data for the first lighting device is downloaded to the mobile device from a configuration database. The first lighting device is physically replaced with a second, replacement lighting device and the second lighting device is identified using the mobile device. The downloaded configuration data corresponding to the first lighting device is then uploaded from the mobile device to the second lighting device and is subsequently used by the second lighting device to control the operation of the second lighting device. The configuration database is then updated based on the identification information for the second lighting device and the configuration data uploaded to the second lighting device from the mobile device.

Configuring lighting electronics using database and mobile device

A connected light node (CLN) induction light ballast module for powering an induction lamp includes a printed circuit board having components mounted thereon and an earth ground region electrically isolated from a PCB ground region. A heat sink is disposed on a lower layer of the printed circuit board and electrically connected to the earth ground region, wherein a parasitic capacitance occurs between the printed circuit board ground region and the heat sink. A capacitive shield sandwiched by a lower insulating pad and an upper insulating pad is electrically isolated from the heat sink supporting the shield. A damping network electrically connects the capacitive shield to the PCB ground region. Switch-mode power converters are mounted above the upper insulating pad and the shield. The damping network suppresses noise by a parasitic capacitance between the PCB ground region and the heat sink during high frequency power converter operation.
