  • Light degradation sensing led signal with visible fault mode
    Patent number: 6667623
    Abstract: A light emitting diode (LED) signal with an LED light output monitoring sensor. If the LED light output drops below a pre-set level, an output signal of the sensor via a comparator and deactivation circuit, deactivates one or more LEDs creating a visible fault display aspect, thereby visually indicating signal failure but allowing a continued use of the signal prior to replacement.
    Type: Grant
    Filed: November 7, 2001
    Date of Patent: December 23, 2003
    Assignee: Gelcore LLC
