Taiwanese LED chip manufacturer Arima Optoelectronics Corporation (AOC) has released a statement on Thursday stating it is assessing whether Chinese competitor San’an Opto’s AlGaInP LED products had infringed its wafer bonding technology patents.

Epistar announces today the successful development of a new AlGaInP LED with record-breaking efficacy of 133 lm/W. Applying the company's novel light-extracting technology, Epistar’s newest additions to its PX series of chips continue to push the envelope on energy efficiency and lighting quality. At a dominant wavelength of 613 nm, the small chip in the PX series reaches 133 lm/W driven by 20mA, while the power chip in the same series reaches 110 lm/W at 350mA.
