Recently, Koito Manufacturing Co Ltd has made use of the design freedom of LEDs to designed a head lamp and showcased it at the 42nd Tokyo Motor Show 2011.

The head lamp, named "Ganriki" (eye force), is shaped like a human eye and the most distinctive feature is its winker lamp (the part emitting yellow light in the picture).

The LEDs vertically arranged on the fender side emit light downwards and inward while the LEDs horizontally arranged at the bottom emit light inward. The emitted light is guided to the light guiding path made by injection molding of polycarbonate or acryl. As a result, the entire light guiding path emits lights.

According to the company, it has overcome the difficulty of light guiding paths ‘ thickness in which light flows uniformly by using injection molding. The company has been developing a technology to improve the dimensional accuracy of injection-molded parts and can ensure the required dimensional accuracy by improving the shape of the metal mold and optimizing the temperature control mechanism of the mold.
