摘要： Systems, methods, and computer program products for remote configuration of one or more power supplies, particularly lighting power supplies, are disclosed. A configuration signal that includes a setting for a parameter is generated and then transmitted to a power supply. The power supply decodes the configuration signal and, if one or more certain conditions are met, configures the power supply according to information provided in the configuration signal.

摘要： Lighting control interface techniques and corresponding circuitry are provided. The techniques include receiving a first signal potentially representative of a first lighting control signal, and receiving a second signal potentially representative of a second lighting control signal, and determining if either of the first and second signals complies with a first or second lighting control protocol. The lighting control signal may be applied to the same interface connector (regardless of the protocol), thereby eliminating the need for separate dedicated interface connectors. In some cases, the techniques further include determining that a dummy control signal is manifesting in the first and/or second signals, thereby indicating that no lighting control signal is being applied. Depending on the resulting determination, the techniques may include, for example, setting output lighting power according to a pre-established value, or according to the first or second lighting control protocol.

摘要： A driver circuit includes a plurality of switches, forming two switching legs, each of at least two switches and connected between two DC voltage buses. The switches are matched to form diagonal pairs. The driver circuit also includes a load circuit connecting the legs, with a first inductor connected between one leg's switches, and a second inductor connected between the other leg's switches, and lamp terminals between the inductors and in series with the second inductor. The driver circuit also includes a capacitor in parallel with the series-connected lamp terminals and the second inductor, and a control circuit connected to the plurality of switches. During a commutation period, a diagonal pair operates in a non-conductive state and the other in a conductive state, until a current through the first inductor reaches a predefined value. Then the other operates in a non-conductive state until the current through the first inductor reaches zero.

摘要： Methods of protecting an electrical device, such as a ballast, from damage due to an inrush current, and devices incorporating such methods, are disclosed. A loss of input power received by the ballast is detected. In response, the ballast is entered into a standby mode. The ballast is able to remain in the standby mode for a standby period of time. The input power is monitored during the standby period of time to measure a start time. Measurement of the start time is triggered by the ballast receiving input power again. The ballast is entered into an active mode when the measured start time exceeds a protection time. The protection time corresponds to an amount of time needed for an inrush current to dissipate following input power again being received by the ballast, protecting the ballast from possible damage due to the inrush current.
