First Claim
Patent Images
1. An automotive lamp assembly comprising:
- a light source to emit a supply of light, the light source being a single incandescent light bulb;
an elongated cylindrical light pipe having a first end and a second end, an elongated cylindrical portion of the light pipe extending between the first end and the second end of the light pipe, said first end of said light pipe spaced apart from the light source and configured to accept said supply of light from said light source to carry the supply of light from the first end to the second end of the light pipe to illuminate the light pipe, the first end of the light pipe positioned adjacent to the light source, the elongated cylindrical portion of the light pipe extending away from the light source;
a reflex reflector mounted on a side of an automotive vehicle within an automotive headlamp, the reflex reflector having a first surface, the first surface having a plurality of teeth, the first surface further including a cutout portion adjacent to the plurality of teeth, the reflex reflector spaced apart from the first end of the light pipe, the reflex reflector spaced apart from and not connected to the light pipe, the reflex reflector positioned to allow a first beam of light from the light source to pass through the reflex reflector to deliver the light to an exterior of the vehicle, the light pipe positioned to allow a second beam of light from the light source to travel down the light pipe; and
wherein said light source, said light pipe and said reflex reflector are positioned adjacent one another enabling said light source to simultaneously provide light to both said light pipe and said reflex reflector.

Abstract
The present invention provides a headlamp assembly including a light pipe and reflex reflector integration utilizing a single bulb to illuminate both the reflex reflector and the light pipe, simultaneously. The headlamp assembly includes a single light source, a light pipe and a reflex reflector positioned adjacent one another allowing the light source to provide light to both the reflex reflector and the light pipe. The reflex reflector includes a reflecting element and a cutout to allow light to pass though the reflex reflector into the reflecting element. The reflex reflector is adapted to transform light from white to amber thereby creating the side marker function. The headlamp assembly further includes a reflector behind the light source to direct light into the light pipe. The automotive headlamp assembly provides an automotive headlamp assembly that includes a reflex reflector light and a light pipe while reducing cost and decreasing weight.
