Koito Manufacturing Co. Ltd.

Single LED Bi-functional Projector Headlamp

Before Koito innovated a standardized compact dual beam LED unit, the high beam – low beam LED applications needed to use multiple LEDs and two lens systems. These systems were large, costly, heavy and did not enable standardization. Koito’s innovation LED Compact Family, is uniquely enabled by two patented inventions: sub-reflectors which provides very high light spread and reach, plus an internal mechanical light shaping mechanism, which doesn’t need to shade. Thus this dual beam LED unit doesn’t waste generated light and it uses a single LED for all modes of operation. The result, is a single compact unit can employ single beam, AFS Adaptive Front-lighting System, and also a dual beam ADB Adaptive Driving Beam.
