Harison Toshiba Lighting Corp has developed
a new, unique SMD LED package called "O2PERA" (Optimized OutvPut
by Efficient Reflection Angle).
The SMD LED has been applied to automotive interior lighting, rapidly replacing the conventional incandescent lamps. The package is comprising a LED die on the leadframe encapsulated with transparent epoxy resin framed by high-reflective white resin. Harison Toshiba Lighting Corp achieved approximately 30% improvement of output efficiency using this "O2PERA" package. Only the internal reflection structure is optimized with the external dimension and its manufacturing cost unchanged. Beside its advantage of 30% brighter performance for the same driving currents, it saves the energy by 30% keeping the same brightness.
