  • Light emitting diode light bar
    Patent number: 6948840
    Abstract: A lighting fixture is disclosed which provides a substantially uniform elongated light output, yet is powered by only a minimum number of inexpensive light emitting diodes. The lighting fixture has a curved back surface and a selected focal area to provide a substantially uniform output. Multiple LEDs may be controlled by a controller to provide special lighting effects. Each of the side surfaces and the back surface may include a reflector. The lighting fixtures preferably have flat end surfaces so they may be placed end-to-end to create an elongated light bar of any desired length.
