R&D and innovation are the future of LED companies

The 11th China International Semiconductor Lighting Forum, in the face of the audience's layout on the future of Samsung, Samsung LED China General Manager Tang Guoqing told everyone: Samsung puts the most energy on research and development, not only for the existing Products, more are the development and innovation of future products. Tang Guoqing said that the current status of the LED lighting industry indicates that the current SMEs are facing survival problems. The idea of ​​the 20,000 companies proposed by Secretary Dou Linping to the last 5,000 is unlikely because he believes that according to the lighting industry. Regularly, this number should be less. Tang Guoqing said that many big companies do not take innovation as their responsibility. What they want to do is how to put the quantity up, but not focus on the core technology. At the same time, he calls on powerful enterprises to work hard on scientific research. . It is understood that China's total investment in research and development has exceeded 2% of total GDP, which is close to that of developed countries, and LED R&D growth is the highest in the world. However, there is still a clear gap between China's LED technology level and advanced countries. In the core patent.

Auxiliary equipment. Welding installations consist of components designed to locate the workpiece in the position most convenient for welding, to turn the workpiece around during welding or during service operations in the weld zone, and to mount and transport the welding apparatus. Roller-conveyor, spindle, chain, pivot-type, and lever tilters are used to locate parts in a convenient welding position. Rotators with vertical, inclined, or horizontal axes of rotation are used to rotate the article being welded. Workpieces are fastened and turned using a disk chuck or a guide (for center rotators) or rollers (for roller-type rotators). Roller-type rotator stands are frequently used in welding cylindrical articles; the drive rollers of such rotators are usually rubber-coated. Shop and welding manipulators are used to turn workpieces around their axes in those cases where the spatial position of the axis is changed during welding. Overhead platforms, rail tracks, and special fixtures that grip the workpiece are used to mount and transport automatic and semiautomatic welders, to suspend the apparatus above moving workpieces, and to transport the apparatus along a weld seam or from weld to weld.
