ABSTRACT:
A long, thin illuminated line of light is provided for highlighting components in an automotive dashboard or interior such as a cup holder or gearshift console. A point light source such as a surface mounted LED or incandescent lamp is located at one end of a light guide. An arcuate rear reflecting surface of the light guide causes total internal reflection of the light from the point light source and produces a uniform light display at a front viewing surface. The line of light can fit into deep recesses of a plastic molded console with minimal spacing (e.g., of only about 0.10 inches) between walls. The line of light can also be used for aesthetic or functional displays such as for consumer electronic equipment and industrial controls.
