Patent number: 7425798Abstract: The inventive signal incorporates an intelligent diagnosis module inside a light emitting diode (LED) signal, such as an LED traffic signal. The inventive signal can self-extinguish or send a signal through its communication port at the end of its useful life when the LEDs are no longer providing the required light output. Additionally, the inventive signal sends a signal to increase the current as the LEDs degrade to ensure the light output is above a threshold minimum.Type: GrantFiled: March 30, 2005Date of Patent: September 16, 2008Assignee: Lumination LLCInventor: Nicolas St.-Germain

Patent number: 6642666Abstract: A railway searchlight signal uses a printed circuit board populated by three arrays (green, red and yellow) of LEDs. The LEDs are lit by a standard color light power supply unit (PSU). As only one array of LEDs is lit at a time, an interface between the PSU and the LEDs is provided to select which LED array to couple with the PSU. External repeater contacts provide information on which aspect is displayed. This searchlight system design is failsafe in that no single failure of a component will produce a less restrictive aspect.Type: GrantFiled: October 20, 2000Date of Patent: November 4, 2003Assignee: Gelcore CompanyInventor: Nicolas St-Germain
