High power red LED for projection light source OSRAM

Germany OSRAM Opto Semiconductors (OSRAM Opto Semiconductors GmbH) announced that the developed driving current of 350mA luminous efficiency is as high as 119lm/W red led. The product uses the company's high power red LED chip "Thinfilm" technology, luminous efficiency increased by about 30% compared with the original. According to OSRAM, the luminous wavelength of 615nm, the luminous efficiency of the wavelength (when the input 350mA current), a new record". When the driving current is 70mA, the luminous efficiency is 136lm/W. The development of the red LED red LED chip will be included in the OSRAM called Golden DRAGON Plus package. The luminous flux of 400mA current is 100lm. "Scheduled for the next 1 years to achieve the product" (the company), is expected to be mainly used in the projector light source, but also envisaged for general lighting purposes.
