On April 20th, “2017 OSRAM Opto Semiconductors Solid State Lighting Innovation Product Technology Seminar†was successfully held in Shenzhen. This event is the third stop of the series seminar. Dr. Shao Jiaping, Head of General Lighting Sales, Osram Opto Semiconductors Greater China, Dr. Chen Wencheng, Head of Application Technology Department, Mr. Wu Sen, Head of Marketing Department, and Senior Industry Researcher, LED inside Mr. et al. attended and spoke and communicated with the industry insiders on the development trend of the industry and the latest developments of OSRAM Opto Semiconductors.
“Focus on the LED market and continuous research and development of LED cutting-edge technology, this is the key to our development.†Dr. Shao Jiaping, head of general lighting sales for OSRAM Opto Semiconductors Greater China, said, “Reviewing the development of OSRAM in recent years, technology and patent advantages, research and development The continuous investment and rapid response to market demand are our strong strengths.†But at the same time, in response to the increase in industry aggregation and industrial scale, OSRAM has also begun to expand its scale. “The upcoming Wuxi LED packaging factory in China. The second phase of the expansion project, and the Malaysian Kulim chip factory, which is expected to be put into operation in December this year, demonstrates our ambition to expand production and make strides forward,†added Dr. Shao.
Dr. Shao Jiaping, Head of General Lighting Sales, Osram Opto Semiconductors Greater China, gave a speech
Dr. Chen Wencheng, Head of General Lighting Application Technology at OSRAM Opto Semiconductors, introduced the cutting-edge technology of the LED industry from a professional perspective. Dr. Chen Wencheng believes that LED technology is constantly developing and mature, and the market demand is more diversified. How to ensure the final performance and quality of LED devices through technological innovation has become the core of the success of major manufacturers. "The core of LED devices is the technology and quality of substrates, chips, phosphors and packages. We have core technologies at these four levels to ensure our quality. The breakthrough in LED technology in the future is mainly from phosphor technology. We have the most advanced phosphor technology and patents, which gives us confidence in the future development," said Dr. Chen Wencheng.
Subsequently, Mr. Chu Yuchao, a senior industry researcher at LEDinside, introduced the development trend of the 2835 package platform, filament lamp and CoB commercial lighting, which have the most potential for LED lighting generation. He said that the 2835 package platform is cost-effective and the price is fierce. Only when the company has a patent can it avoid the quagmire of price competition. Since its introduction in 2012, the filament lamp has been used only for low-power lamps to develop decorative lights and incandescent lamps. Lamp replacement lamps, even expected to develop into a diversified use of fluorescent lamps instead of lamps by 2020, adding more added value to the filament lamps, making a different direction, is the secret to expand the filament lamp market; and for CoB commercial lighting Mr. Chu Yuchao also believes that as more manufacturers enter the CoB field, the price of products also has a downward trend. The key to the development of the CoB market is to insist on differentiation and make higher-end products specially designed for different scenarios.
The product line of OSRAM Opto Semiconductors in 2017 coincides with Mr. Chu Yuchao's analysis of the three major market segments. Mr. Wu Sen, Head of General Lighting Marketing Department of Osram Opto Semiconductors, introduced Osram as the main product of indoor lighting in 2017, and will launch a newly developed professional medium and low power OSCONIQ product line; emphasize the patent advantage in the field of filament lamps and strive to expand Product diversity; in the field of CoB, OSRAM will take advantage of existing advantages to further expand the application of specific scenes such as fresh lights. Mr. Wu Sen added that OSRAM will also build a comprehensive product line while focusing on market segments. The existing product range covers a full range of products from medium to low power to ultra high power. It offers both cost-effective and high-end professional products to meet the diverse needs of the market.

1. The blades of an axial fan push air to flow in the same direction as the shaft. The impeller of an axial fan is similar to the propeller. When it works, most of the airflow is parallel to the shaft, in other words along the axis. When the inlet airflow is free air with zero static pressure, the axial flow fan has the lowest power consumption. When operating, the power consumption will increase as the airflow back pressure rises. Axial fans are usually installed in cabinets of electrical equipment, and sometimes integrated on motors. Because of their compact structure, they can save a lot of space and are easy to install, so they are widely used.
Its characteristics: high flow rate, medium wind pressure
2. Centrifugal fan
When the centrifugal fan works, the blades push air to flow in a direction perpendicular to the shaft (ie, radial), the air intake is along the axis direction, and the air outlet is perpendicular to the axis direction. In most cases, the cooling effect can be achieved by using an axial fan. However, sometimes if the airflow needs to be rotated by 90 degrees or when a larger wind pressure is required, a centrifugal fan must be used. Strictly speaking, fans are also centrifugal fans.
Its characteristics: limited flow rate, high wind pressure
3. Mixed flow fan
Mixed flow fans are also called diagonal flow fans. At first glance, mixed flow fans are no different from axial flow fans. In fact, the air intake of mixed flow fans is along the axis, but the air outlet is along the diagonal direction of the axis and the vertical axis. Because the blades and outer cover of this fan are called conical, the wind pressure is higher. Under the same size and other comparable performance, the centrifugal fan has lower noise than the axial fan.
Its characteristics: high flow rate and relatively high wind pressure
4-flow fan
Tubular wind flow can produce a large area of wind flow, which is usually used to cool large surfaces of equipment. The inlet and outlet of this fan are perpendicular to the axis (see Figure 1). The cross flow fan uses a relatively long barrel-shaped fan impeller to work. The diameter of the barrel-shaped fan blade is relatively large. Because of the large diameter, it can use a relatively low speed on the basis of ensuring the overall air circulation. , Reduce the noise caused by high-speed operation.
Its characteristics: low flow rate, low wind pressure
