  • Light-emitting diode combination marker/clearance lamp for trucks and trailers
    Publication number: 20020044454
    Abstract: The present invention is a vehicular combination marker/clearance lamp for trucks and trailers using a reduced number of light-emitting diodes and an optics design using total internal reflection to produce the light intensity and angular distribution required by the Department of Transportation. The present invention accomplishes this goal by utilizing a one-piece optical system. The system possesses a collimating lens, ribbed structures, and a modified conical shape, which will concentrate and distribute the light produced by the light-emitting diodes.
