Recently, with the support of the Chongqing Science and Technology Project, the Integrated Photoelectric Technology Research Center of Chongqing Institute of Green Technology, Chinese Academy of Sciences, made important progress in the application research of UV LED freeform surface light distribution technology. The successful application of UV LED light source in the field of exposure machine , Products have been PCB, LCD panels, touch-screen applications such as access. The relevant achievements have obtained the national patent authorization (Patent No .: for the ultraviolet LED alignment lens.0, high uniformity UV LED exposure head.4). The traditional parallel light exposure machine uses a high-pressure mercury lamp as a light source, which has a lifetime of only 1000 hours, high power consumption, and pollution. UVLED replace mercury lamp light source, life expectancy up to 50 times the mercury lamp, power consumption can be reduced by 90%, significantly reduce production costs, environmental pollution. At present, Chongqing Research Institute has broken through the LED multi-free surface with precise light distribution, suitable for the UV-band inorganic optical components processing and other key technologies for the first time developed based on UV LED parallel light exposure head, parallel half-angle can be controlled within ± 2 °, Lighting unevenness of less than 3%, lighting intensity up to 40mW / cm2. Self-developed part of the UV LED exposure head and light source module Water/Wet type wire drawing machine LT23-25/288 water tank wire drawing machine Water/Wet Type Wire Drawing Machine,Water Type Wire Drawing Machine,Wet Type Wire Drawing Machine,Water Tank Wire Drawbench Jiangyin Wanyi Machinery CO.,Ltd , https://www.wydrawmachine.com
