摘要： A lamp driver delivers an output voltage and output current to a lamp load. A current regulating circuit at a secondary side provides a feedback signal for use by the driver when in a current regulation mode. An overvoltage protection circuit detects an overvoltage condition of an output voltage and modulates the feedback signal during detection of the overvoltage condition. The overvoltage condition can then be recognized more easily based on the resulting modulation of the output voltage.

摘要： A light emitting unit is configured to be applied to a surface area of a marine vessel and includes at least one light source configured to emit anti- fouling light (e.g., UV light), and two electrically conductive plates. One side of the at least one light source is electrically connected to one of the plates and another side to the electric energy distribution arrangement of the light emitting unit. The plates are arranged to form respective capacitors with an electrically conductive area of, or over, the surface of the marine vessel, the capacitors connected in series through the electrically conductive surface area once the light emitting unit is applied to the surface the marine vessel.

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： The present invention relates to an LED lighting circuit that receives feedback on the final voltage output applied to LEDs and performs PWM control to regulate current flowing through a transformer unit, rectifies voltage of a secondary side of the transformer unit, and smoothens power and blocks surges by an output-side smoothing and surge protection unit to supply to the LEDs. The LED lighting circuit generates output as a high signal or a low signal whenever a microcomputer is turned on/off, so that the capacitor smoothens power at a high output, and when the output is low, suppresses transient voltage to extend the lifespan of the smoothing capacitor.

摘要： A voltage sensing circuit uses a voltage divider for providing a sense signal indicating the voltage across a circuit component. A current injector is used for injecting current to the sensing terminal. A sense signal is obtained with no current injection, to determine if a fault is present. The sensing terminal is coupled to the external circuit component via a voltage clamping component. A further sense signal is obtained in response to the injection of current. By comparing the sense signal in response to the injected current and a clamping voltage of the voltage clamping component, it can then be determined if the fault is caused by the circuit component or by the voltage divider.
