  • LED-illuminated stop/tail lamp assembly
    Patent number: 5765940
    Abstract: The present invention relates to an LED-illuminated lamp assembly which includes a lens that is capable of directing light from the LEDs both horizontally and vertically. The taillight mode is also directed slightly upward so as to comply with applicable lighting regulations. The lamp assembly also includes a current regulating assembly which is mounted within the housing and attached to a power source for providing current to LEDs positioned within the housing. The LEDs are mounted on an LED board assembly. The current regulating assembly is capable of maintaining steady current through the LEDs independent of the power source voltage so as to prevent an overheating of the LEDs at higher than normal voltages and to provide constant, non-flickering light output with varying input voltages.
