  • Current shaping of an LED signal for interfacing with traffic control equipment
    Patent number: 7701150
    Abstract: A system creates a desired current level within a traffic signal. A power supply unit receives an external power signal and transforms the power signal to a lamp current. A pulse generator monitors the value of the lamp current and automatically adjust the power usage of the current sink circuit to maintained a predefined current amplitude. A current pulser generates square current pulses at a frequency based at least in part on the frequency of the lamp current. A current sink superimposes the rectangular current pulse onto the lamp current and outputs a combined power signal to the alternating current power line.

  • Module for powering and monitoring light-emitting diodes
    Patent number: 6762563
    Abstract: LED lamp circuitry that emulates an incandescent lamp's behavior upon remote verification of the LED lamp. The LED lamp circuitry presents an input power switch circuit, a fuse blow-out circuit and a cold filament detection circuit permitting the use of LED lamps in applications, such as railway signal light applications, where there is a need for remote monitoring of the lamps, while keeping the advantageous features of lower power consumption and longer life.
