摘要： An illumination system has a controller stack that includes multiple power conversion and LED driver assemblies and a pole-mounted backplane that provides power and communication connections. The pole-mounted backplane further acts as a heat-sink and efficiently transmits excess heat to the pole on which the controller stack is mounted. The controller stack and its components include weathertight housings and connectors for outdoor applications, and it includes a master, which monitors the system operation and can switch to a backup LED driver based upon its monitoring of system operation.

摘要： A lighting system includes a plurality of lamps configured to operate in an on mode and in an off mode. The plurality of lamps include C×N lamps, wherein C is a number of channels and N is a number of lamps per channel. The lighting system includes a plurality of electronic switches coupled to the lamps to switch the lamps between the on and off modes. A power source provides the lamps with operating power. A controller is electrically coupled to operate the electronic switches. The controller includes timing circuitry to control time each lamp is in the on mode and the off mode. Within a given time period, the amount of time each lamp is in the on mode is less than the amount of time each lamp is in the off mode. The frequency at which each lamp is in the on mode is at least 60 Hz.

摘要： A load control device for controlling power delivered from a power source to an electrical load may comprise a control circuit configured to control the load regulation circuit to control the power delivered to the electrical load. The control circuit may be configured to operate in an AC mode when an input voltage is an AC voltage and in a DC mode when the input voltage is a DC voltage. The control circuit may be configured to disable the power converter in the DC mode. The control circuit may be configured to render a controllable switching circuit conductive in the AC mode, and non-conductive in the DC mode. The rectifier circuit may be configured to rectify the input voltage to generate a rectified voltage when the input voltage is an AC voltage, and to pass through the input voltage when the input voltage is a DC voltage.

摘要： A load control device for controlling the amount of power delivered from an AC power source to an electrical load is operable to conduct enough current through a thyristor of a connected dimmer switch to exceed rated latching and holding currents of the thyristor. The load control device comprises a controllable-load circuit operable to conduct a controllable-load current through the thyristor of the dimmer switch. The load control device disables the controllable-load circuit when the phase-control voltage received from the dimmer switch is a reverse phase-control waveform. When the phase-control voltage received from the dimmer switch is a forward phase-control waveform, the load control device is operable to decrease the magnitude of the controllable-load current so as to conduct only enough current as is required in order to exceed rated latching and holding currents of the thyristor.

摘要： An LED light string control system includes an LED light string, a voltage generation apparatus, and a control module. The control module controls the voltage generation apparatus to change a signal provided to the LED light string to a first voltage level according to a first logic of a light command, and changes the signal to a second voltage level according to a second logic of the light command. The control module controls the voltage generation apparatus to change the signal to a distinction voltage level once the first logics and/or the second logics of the light command appear consecutively.
