LEDs drive the evolution of lighting, and its overall market growth is strong and will continue into 2020. At the LEDforum2014 China International LED Market Trend Summit, hosted by industry bodies, Michael Schmitt, Director of Solid State Lighting Marketing for OSRAM Opto Semiconductors Asia Pacific, said.
Michael Schmitt said lighting consumption will continue to grow, driven by global GDP, and the shift to solid-state lighting is the main driver of growth. This is undoubtedly a good news for the current lighting market's LED lighting.
Of course, the development of LED lighting is not likely to happen overnight. Although the national ban policy has been introduced one after another, bringing a wide range of LED light source replacement tide, traditional lighting will still maintain a certain market share in a short period of time. Michael Schmitt said in his speech that the traditional lighting market will remain resilient until 2016 due to the continuous shift to green lighting.
At the LEDforum2014 China International LED Market Trend Summit Forum, Michael Schmitt paid close attention to the status of the commercial lighting market. He used graphs to show the different requirements for light parameters in different segments. Among them, architectural landscaping and hotel lighting have little difference in light parameters, and have high requirements in color rendering index, cost performance and service life. The most important value for money is home lighting, while industrial lighting is more focused. Light efficiency and service life.
In terms of store lighting, Michael showed the importance of lighting solutions to the store: perfect lighting turns the shop window into a showcase, making the merchandise dazzling and attracting passers-by. Good lighting effect can guide customers into the store, making the store a soft and pleasant atmosphere, making the products dazzling and attracting customers' desire to buy. Studies have shown that contrast is more important than brightness for store lighting, so current store lighting uses narrow beam spotlights to create an atmosphere that contrasts the surrounding environment.
In addition, Michael Schmitt also introduced OSRAM's unique chip technology UX: 3 (SOLERIQP), which was originally developed exclusively by OSRAM in 2010. It is understood that the UX:3 chip has built-in n-type contact electrode, which can produce higher quantum efficiency, and can reduce Auger recombination, and solve the problem of LED efficiency degradation at high current. Michael Schmitt showed the comparison of UX:3 technology and SOLERIQS. UX:3 uses surface illuminating, SOLERIQS uses volume illuminating. In contrast, UX:3 emits more uniform light. UX:3 can be densely arranged to reduce package size. SOLERIQS technology must reserve a certain interval to avoid re-absorption; in terms of luminous flux, UX:3 has a wider range of lumens, while SOLERIQS is relatively limited. In comparison, the advantages of UX:3 chip technology are already very obvious.
In terms of the choice of light source quality, high light efficiency and high color rendering are the key to LED. However, the color rendering index of warm white or neutral white LEDs on the market is usually low, and various methods are used to increase the color rendering index, usually accompanied by loss of light efficiency. Michael pointed out that in a single LED, high light efficiency and high color rendering are like fish and bear's paw, not both. The BrilliantMix color mixing LED technology developed by OSRAM effectively solves this problem. It provides 110lm/W high luminous efficiency and a color rendering index higher than 90. Its color temperature can be adjusted from 2700K to 6000K. BrilliantMix color mixing LED is very suitable for high-end. The retail industry offers products that combine high color rendering and high light efficiency, which is consistent with OSRAM's focus on commercial lighting.
It is noteworthy that although OSRAM did not have any booths at this Guangya exhibition, it held a LightisOSRAM-themed customer event in Guangzhou during the June 11th exhibition. Showcases general and specialty lighting products and solutions that cover a wide range of commercial lighting, including commercial chains, hotels, roads, architectural beautification, and home. This shows that OSRAM attaches great importance to the commercial lighting market.
