    摘要: A vehicle lighting system receives power from a power supply and includes a lighting control module, a lamp, and a ballast having a bias control circuit. The lighting control module provides a remote enable signal to the ballast in response to an input. The bias control circuit of the ballast receives a supply voltage from a power supply and the remote enable signal and selectively energizes a bias regulator circuit of the ballast as a function of the remote enable signal. When the bias regulator circuit is energized, a controller of the ballast operates the ballast to provide power from the power supply to the lamp.

    摘要: A thermal protection circuit, and system and method including same, is provided. The circuit includes a variable impedance circuit configured to be coupled to a constant current source and a plurality of solid state light sources. The constant current source provides a current to the plurality of solid state light sources and provides an output voltage to establish a supply voltage for the circuit. The circuit also includes a temperature sensor configured to sense a temperature of the plurality of solid state light sources. The circuit also includes a control circuit configured to receive the supply voltage and to drive the variable impedance circuit based on the sensed temperature, to adjust the current to the plurality of solid state light sources when the supply voltage is a least a minimum supply voltage of the control circuit.

    摘要: A current sensing circuit for sensing the current provided to LEDs by a constant current power source includes a resistive shunt in series with the load and a current mirror having a first leg connected to a first terminal of the resistive shunt and a second leg connected to a second terminal of the resistive shunt. Both legs of the current mirror are also connected to ground. The first leg provides a reference signal to the second leg, and the second log uses the reference signal and a voltage at the second terminal of the resistive shunt to provide a ground referenced output signal indicative of the current provided to the LEDs.

    摘要: A handheld rangefinder device operable to determine ballistic hold over information is disclosed. The rangefinder device generally includes a range sensor operable to determine a first range to a target, a tilt sensor operable to determine an angle to the target relative to the device, and a computing element, coupled with the range sensor and the tilt sensor, operable to determine a hold over value based on the first range and the determined angle. Such a configuration facilitates accurate firearm and bow use by providing ranges and hold over values without requiring time-consuming and manual user calculations.
