The Institute of Chemistry of the Chinese Academy of Sciences announced the latest achievements in LED lighting technology

The Institute of Chemistry of the National Institute of Science and Technology has participated in the 2015 Taiwan International Lighting Technology Exhibition since the 25th. The exhibition will showcase the research and development results of the LED lighting industry raw materials, fluorescent powder and packaging materials. Lai Yaoxiang, director of the Institute of Chemistry of the Chinese Academy of Sciences, said that the chemical industry's LED lighting industry has been working hard for a long time. Using the special physical properties of composite ceramics, it has introduced composite ceramic LED lamps to gradually replace the alumina substrates and tantalum substrates used in current LEDs. Taiwan factory Mingjing, Taiwan semiconductor lighting cooperation for patio lights, street lights and so on. The Institute has implemented and responded to the policy of the Green Energy Low Carbon Promotion Council of the Executive Yuan and supported by the Technical Department of the Ministry of Economic Affairs. It has continued to develop in the fields of smart lighting component development, back-end R&D applications and basic research. At present, a number of LED technologies have been completed. Developed and proposed dozens of patent applications. In addition to exhibiting the aluminum nitride raw material technology of the LED lighting industry, Chen Zhan also highlights the key technologies required for LED lighting: fluorescent powder and packaging materials. In terms of phosphor powder, the formulation is designed to derive novel red nitride phosphors to improve brightness, color rendering and thermal properties. At the same time, the two-phase composite UV-excited nitride phosphor powder technology can be used to reduce the manufacturing cost of the phosphor powder. In terms of packaging materials, the epoxy conductive silver paste for LED module packaging and the conductive silver adhesive for packaging are developed, which is cost-effective and fully mastered in technology. The LED lighting market is growing, and the United States, Japan, South Korea and other countries continue to invest a lot of resources. The Institute of Chemistry of the Chinese Academy of Sciences uses the existing research and development energy, actively tutors domestic enterprises, vertically integrates the resources of the industry chain, and establishes the completeness of aluminum nitride LEDs in China. Industry supply chain, together with the industry to develop technologies related to smart lighting systems. Through the industry alliance, we will create China's independent industrial technology and equipment products, and enhance the value of the overall LED lighting products. We will be able to achieve international leading position in technology and application. Under the guidance of the Green Energy Low Carbon Promotion Council of the Executive Yuan and the Technical Department of the Ministry of Economic Affairs, the Institute will continue to promote the development of LED energy-saving lamps and conduct cross-disciplinary R&D and alliance through the integration mechanism of domestic production, government, learning and research. In addition to effectively improving China's economic development, it will better focus on energy conservation and carbon reduction and create a win-win situation.

Low Noise Laser

The low noise issues of lasers are due to the competition of mode in Laser resonant cavity, which lead to high frequency jitter of output power. Through special design for laser resonant cavity and other components, the laser amplitude noise can be reduce efficiently. CNI low noise laser can be widely applied to DNA sequency, cell sorting, spectrum analysis, interference measurement, laser holography, photo processing and biomedical and other fields.

CNI offers low noise lasers in wavelengths from ultraviolet to infrared (360~1550 nm).
