METHOD AND APPARATUS FOR CONTROLLING LIGHT ATTRIBUTES OF LIGHTING DEVICE, AND LIGHTING SYSTEM
Provided is a method and apparatus for controlling light attributes of a lighting device, and a lighting system and includes an indicator that receives an input, and sends to a control unit, a signal for switching light attribute of the lighting device; and the control unit determines whether a first switching signal or a second switching signal from the indicator is received during a light emission period after the lighting device is powered on, and if it is determined that the first switching signal is received, switching a current light attribute to another light attribute, or if it is determined that the second switching signal is received, switching the current light attribute to a light attribute indicated by the second switching signal such that when a specific light attribute is indicated by the second switching signal, the light attribute can still be adjusted with the first switching signal.
Load control device having a closed-loop gate drive circuit including overcurrent protection
A load control device for controlling power delivered from an AC power source to an electrical load may have a closed-loop gate drive circuit for controlling a semiconductor switch of a controllably conductive device. The controllably conductive device may be coupled in series between the source and the load. The gate drive circuit may generate a target signal in response to a control circuit. The gate drive circuit may shape the target signal over a period of time and may increase the target signal to a predetermined level after the period of time. The gate drive circuit may receive a feedback signal that indicates a magnitude of a load current conducted through the semiconductor switch. The gate drive circuit may generate a gate control signal in response to the target signal and the feedback signal, and render the semiconductor switch conductive and non-conductive in response to the gate control signal.

Method of controlling an agricultural vehicle lighting system and system thereof
An agricultural work vehicle for operating in a field includes a chassis, a cab mounted to the chassis, a controller for controlling operation of the work vehicle, and a lighting system including a array field light. The array field light projects a light emission to illuminate a defined zone. A light control module is disposed in electrical communication with the controller and operably controls the at least one array field light. A sensing device senses an area surrounding the work vehicle. The sensing device transmits a signal indicative of a detected object to the controller, which in turn determines if the detected object is in the defined zone. If the detected object is in the defined zone, the light control module controllably adjusts an output from the array field light so that only a portion of the defined zone in which the object is not located is illuminated.
