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: 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 method and apparatus for an adaptable vehicle light mount is provided. A recess created within an interior of a heat sink fin array of the vehicle light allows associated mounting hardware to be embedded within the recess. A physical offset between the vehicle light and the associated vehicle may therefore be minimized to provide a shallower mounting profile. A tube may be incorporated into the recess so as to allow one or more vehicle lights to be mounted to a single mount point on a vehicle where the tube and associated mounting hardware are incorporated and function as part of the heat reducing components of the vehicle light.

摘要: A high power factor control circuit is disclosed, which is used in an AC/DC converter. The converter includes a rectification module, a conversion module and a load. The rectification module receives AC power and rectifies it into a DC current, and the conversion module converts the DC current to drive power as desired by the load and provides it to the load. The conversion module includes a conversion element including an inductive element and a switching element. The control circuit includes a peak limiting signal generator and a switching element control module. The peak limiting signal generator receives a reference signal and produces at least one peak limiting signal from a sample signal. The switching element control module is configured to control switching of the switching element so that, within at least half a line-frequency period, a value of the ripple in the output current flowing through the load is not greater than a limit value.
