Abstract: The LED replacement for low voltage lamps has a plurality of LED lights disposed in a housing capped by a multifaceted reflector to provide lighting having comparable lighting characteristics to non-LED sourced low voltage lamps. Power conditioning solid state circuitry is disposed in the housing and provides the LED lights with a regulated excitation voltage source. The power conditioning circuitry has at least one ceramic capacitor in parallel with output leads of a power supply for the lamp. A zener diode pair having anodes connected together is disposed in parallel with the ceramic capacitor. The power conditioning circuitry is disposed in advance of a voltage rectifier and filter bank, whose output is provided to a voltage regulator that provides regulated DC voltage to the LED light sources. Output of the voltage regulator is modulated by thermal protection circuitry that throttles the LEDs off responsive to lamp overheating.

Abstract: The Low profile LED lighting assembly includes a housing, a circuit board, a plurality of LEDs, and a plurality of reflector assemblies. The circuit board provides wiring and power to thirty-two LEDs arranged in the housing. Each LED is surrounded by a reflector assembly and arranged within the housing to provide a relatively uniform and bright central region to illuminate a predetermined space beneath the device. Each LED and reflector assembly is adapted to illuminate a portion of the total target area. The reflector assembly has five asymmetrical facets surrounding each LED to direct the LED light output to a region within the narrow region of the target space. Repetition of this arrangement results in a light distribution pattern that covers the entire target area.

Abstract: The invention is directed to a neutral sensing switch for use with a remote vehicle starter to prevent the vehicle starter from starting a vehicle unless the shift lever for the transmission is in the neutral position. The neutral sensing switch includes a transmitter mounted on top of a shift lever which transmits a signal generally towards a receiver. The transmitter and receiver are both connected to a processing circuitry of a controller. Based on the signal detected by the receiver, the controller determines whether the shift lever is in the neutral position.
