Abstract: Techniques presented herein are directed to synchronizing the execution time of lighting operations within a networked lighting system. In one example, a network device that is connected to at least one networked light fixture accepts one or more timing reference messages representing a network time base. The network device generates one or more lighting control messages that identify at least one light control setting for the networked light fixture connected to the network device. Based on the one or more timing reference messages, the network device encodes a time for execution of the light control setting within the lighting control messages, thereby generating one or more time encoded lighting control messages. The network device sends the time encoded lighting control messages to the networked light fixture for execution of the light control settings at the time of execution specified in the time encoded lighting control message.

An n-channel transistor in which threshold voltage changes in a positive direction and the amount of the change is small is used. When the threshold voltage of the transistor is obtained, the gate voltage of the transistor is adjusted as appropriate.

Abstract: A three-way load control device may be coupled to a circuit including an AC power source, an electrical load, and an external single-pole double-throw (SPDT) three-way switch. The load control device may include a three-way switching circuit comprising an internal SPDT switch, a relay coupled to the internal SPDT switch, a turn-on delay circuit responsive to a voltage at a movable contact of the internal SPDT switch, and a turn-off delay circuit responsive to voltages at fixed contacts of the internal SPDT switch. The turn-on delay circuit renders the relay conductive after a turn-on delay from when either the internal SPDT switch or the external three-way switch is actuated to turn the electrical load on. The turn-off delay circuit renders the relay non-conductive after a turn-off delay from when either the internal SPDT switch or the external three-way switch is actuated to turn off the electrical load.

When the voltage on the current sensing resistor is higher than the reference voltage or the on time of the low voltage MOS transistor reaches the preset time of the maximum on-time timer, the low voltage MOS transistor is turned off.

Abstract: In one embodiment, a method of driving a load can include: monitoring an AC input to a rectifier circuit in real-time, where the rectifier circuit can include first and second rectifier circuits, and controlling first and second controllable switches based on a state of the AC input is in a first state. For example, a first state can include the AC input being in a positive half cycle and increasing, or the AC input being in the positive half cycle and decreasing while being at least as high as a predetermined threshold value. The AC input can be used to supply power to a load circuit and an output capacitor via the first rectifier circuit when the AC input is in the first state, where the first rectifier circuit can include a first diode and the second controllable switch.
