摘要： A load control device for controlling the power delivered from an AC power source to an electrical load includes a thyristor, a gate coupling circuit for conducting a gate current through a gate of the thyristor, and a control circuit for controlling the gate coupling circuit to conduct the gate current through a first current path to render the thyristor conductive at a firing time during a half cycle. The gate coupling circuit is able to conduct the gate current through the first current path again after the firing time, but the gate current is not able to be conducted through the gate from a transition time before the end of the half-cycle until approximately the end of the half-cycle. The load current is able to be conducted through a second current path to the electrical load after the transition time until approximately the end of the half-cycle.

摘要： An electrical gang box adapted for use with drivers is disclosed. The electrical gang box includes a main compartment with a front opening sized and adapted to accept an electrical control and structure around the front opening to secure the electrical control within the front opening and within the main compartment. The electrical gang box also includes a lower compartment that extends below the main compartment, is set back from the front of the main compartment and is open to the main compartment along an upper portion. The gang box may also include one or more pairs of rails disposed on opposite interior walls. In such cases, a divider panel is sized to slide into and extend between the rails to divide the gang box. Multiple-gang boxes with these features are also disclosed.

摘要： A load control device coupled between an AC power source and an electrical load may operate in a three-wire mode or a two-wire mode based on whether the load control device is connected to a neutral side of the AC power source. The load control device may further comprise first and second zero-cross detect circuits to be respectively used in the two-wire mode or the three-wire mode, and a neutral wire detect circuit configured to generate a neutral-wire detect signal indicating whether the load control device is connected to the neutral side of the AC power source. A control circuit of the load control device may determine whether the load control device should operate in the two-wire mode or in the three-wire mode in response to the neutral-wire detect signal.

摘要： A method for controlling an amount of power delivered to an electrical load may include controlling an average magnitude of a load current towards a target load current that ranges from a maximum-rated current to a minimum-rated current in a normal mode, and controlling the average magnitude of the load current below the minimum-rated current in a burst mode. The burst mode may include at least one burst-mode period that comprises a first time period associated with an active state and a second time period associated with an inactive state. During the burst mode, the method may include regulating a peak magnitude of the load current towards the minimum-rated current during the active state, and stopping the generation of at least one drive signal during the inactive state to control the average magnitude of the load current to be less than the minimum-rated current.

摘要： A lighting driver includes a negative third harmonic generator configured to generate a negative third harmonic signal corresponding to a third harmonic of an AC input voltage shifted by 180 degrees. The lighting driver further includes an adder circuit configured to generate an adder output signal by adding the negative third harmonic signal to a voltage divider output signal generated from the AC input voltage. The lighting driver also includes a controller configured to control generation of a DC output voltage provided by the lighting driver based on a control signal generated from the adder output signal.

摘要： A color temperature switching scheme for an LED lighting device is disclosed. The color temperature switching scheme comprises a plurality of different color temperature performances correspondingly generated by a plurality of different paired combinations of a first electric power allocated to a first LED load emitting a light with a first color temperature and a second electric power allocated to a second LED load emitting a light with a second color temperature such that a mingled color temperature between the first color temperature and the second color temperature can be generated thru a light diffuser. For tuning the mingled color temperature of the LED lighting device a reverse yet complementary power adjustment process for distributing a total electric power T between the first LED circuit and the second LED circuit is required such that a total light intensity remains unchanged while the mingled color temperature is being adjusted.
