Besides the fields of lighting and backlight, the LED demand has also increased in the emerging applications of vehicle, projector and flashlight in these years. LEDinside had the exclusive interview with Dr. Alfred Felder, the President and CEO of OSRAM Opto Semiconductors Asia Ltd., owned by Osram group, and discussed the major LED companies’ view about the future of LED industrial development, as well as the fields which would become the development direction in the future market.

Dr. Alfred Felder, the President and CEO of OSRAM Opto Semiconductors Asia Ltd.

Osram will continue to focus on the market of vehicle application, lighting and consumer electronics

Dr. Alfred Felder previously took the position of the general manager of OLED, the department of the company located in USA, and also worked in Siemens and Infineon Technologies. He believes that the whole LED industry is still the important emerging industry, which has the promising future.

Osram-OS estimates that the global light source market, applied by general lighting, will increase to USD$ 15.9 billion by 2020. On the occasion, LED light source will develop greatly, accounting for 50% of the total market shares. Besides LED illumination, Osram will also focus on the market of vehicle applications and consumer electronics.

The further improvement of LED light source technology

Dr. Alfred Felder says that Osram holds the optimistic attitude toward new ThinGaN technology, which will become the good solution to improve LED light extraction efficiency. This technology will make the LED light extraction efficiency more than 80%, which is more favorable than any previous LED product. The advantage of this technology lies in the fact that GaN based LED component is separated from the original structure and gives off lighting by more effective ways, which will also improve the overall LED IQE efficiency. In addition, Osram will also provides UX:3 technology, which can improve the luminance of white LED by 10%-20%. At present, the Osram’s production capacity has reached 120 lm/w, which is expected for 200 lm/w in the future.

He believes that CRI is one of the important elements for LED lighting products, which is also different on the basis of different situations and applications. The primary task of lighting product manufacturers is to ensure the best quality of LED light source. At the present stage, the Osram LED has achieved the luminous efficiency of 150 lm/w under the LED component with CRI 90 standard.

He also points out that Osram’s Ostar, besides multiple-wafer technology, also has the array design of LED wafer. The company has also developed the LED products with high voltage drive, which will contribute to some specific markets in the future.

Benefited from LED light source, the vehicle lighting product will have more innovations

In terms of the vehicle lighting market, the LED lighting factories will cooperate with vehicle manufacturers to produce more creative and diversified vehicle lamps with the rise of new-model LED light sources, which has been more and more adapted in some vehicle giants’ new senior cars, Hybrids and EVs.

He points out that the new vehicles are required to reduce the CO2 emission under Europe policy. Besides the improvement of engine efficiency, the traditional engine vehicle can also reduce the power consumption of other components, which can not only improve fuel efficiency but also cut CO2 emission. Therefore, the vehicle light sources, from inside to outside, widely use LED products. Regarding the most energy-intensive driving light and the head lamp, with the development of LED manufactures’ technology, the LED lighting has been applied in headlights, which will be used in more and more vehicles in the future.

He emphasizes, the years of experience in vehicle lighting market ensure that Osram still shows high visibility in LED market. At present, the company’s vehicle LED products, including driving lights, take up about 40% of global market.

Pico light source product will be in large scale in the future

In addition, Dr. Alfred Felder predicts that Pico Projector with LED light source will increase to 7 million units in 2013. Besides Pico Projector, the LED light source will also be applied in notebooks, tablet computers, smart phones and digital cameras, which will become the digital equipments with the function of Pico Projector. LED is the best choice for these Pico Projectors. Osram has also prepared a range of products and will cooperate manufacturers to introduce more these products in 2011.

Although the quantity is not very large at the primary stage, he is very optimistic about the market development, and Orsan has also made full preparation.

OLED lighting focuses on commercial space and indoor illumination

Osram has also achieved rapid development in OLED lighting technology. He reveals that OLED light source in the company’s lab can achieve the luminous efficiency of 100 lm/w, which is expected for further development in 2011. The great urgency is to cut the production cost of OLED, and maintain the strong competitive edge in the market of commercial space, residential lighting and office illumination.

He predicts that OLED lighting market will show obvious growth trend in 2012. By 2016, OLED lighting will achieve the commercial success in the fields of cost, production, efficiency and sales.
