Abstract: 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.

Abstract: A network power distribution system includes a plurality of networked digitally controlled lighting devices and a network powered network controller. Each of the digitally controlled lighting devices includes a device driver that coupled to the network. The device driver is selectively transitionable between a first operating mode in which the device driver provides a first voltage and a first current to the network and a second operating mode where the driver does not provide a voltage or current to the network. The network controller autonomously determines a number of device drivers that, in the first operating mode, at least meet the current draw of the network controller. The network controller then transitions the determined number of device drivers to the first operating mode. The network controller monitors the device drivers for faults and autonomously swaps device drivers to maintain network power.

Abstract translation: 提供照明控制接口技术和相应的电路。 这些技术包括接收潜在地代表第一照明控制信号的第一信号，以及接收潜在地代表第二照明控制信号的第二信号，以及确定第一和第二信号中的任一个是否符合第一或第二照明控制协议。 照明控制信号可以应用于相同的接口连接器（不管协议），从而消除对单独的专用接口连接器的需要。 在一些情况下，这些技术还包括确定在第一和/或第二信号中显示虚拟控制信号，从而指示不施加点亮控制信号。 根据所得到的确定，技术可以包括例如根据预先建立的值或者根据第一或第二照明控制协议来设置输出照明功率。
