  • Vehicle lamp fixture and method of use
    Patent number: 6367950
    Abstract: A vehicle lamp fixture is disclosed in which a truncated bowl-shaped reflector 6 is formed as a single unit in front of each respective LED 5. Each reflector is formed from a transparent substance and has an aperture in the front surface. Each reflector also has a reflective surface 6b that totally reflects light from the LED 5 and a light conductive member 6c that conducts at least a portion of light reflected by the reflective surface toward the front of the light fixture. A transparent front lens can thereby be used that does not include light-distributing facets.
