Design of a Novel Multi-Mode LED Dimming and Color Control System

Aiming at the needs of different lighting applications, combined with the characteristics of LED dimming and color control, and using MSP430 digital control technology, a novel LED intelligent dimming and color control system was designed. The system integrated Bluetooth remote, human infrared sensor, voice/gesture control and other control modes, which could achieve LED multi-mode dimming and color intelligent control. System hardware and software were designed to develop a prototype to experimental verification. The designed method proposes new ideas and information for LED control.

新冠肺炎疫情下的逆全球化? 再全球化?

新冠肺炎疫情在世界范围内的暴发给全球化带来挑战与机遇。作为一种非传统安全威胁,疫情蔓延扩散本身就是全球化的突出表现,同时也导致了经济全球化受挫放缓,人员流动的全球化受阻隔绝,给全球化造成巨大冲击。借炒作疫情,质疑、反对全球化的"逆全球化"浪潮卷土重来,"脱钩论"就是其中的典型代表。然而,经济规律与技术进步决定了疫情不会导致逆全球化。全球化是时代潮流、大势所趋,并不会走向终结。相反,标志着全球化扩容升级的"再全球化"将在疫情中加速到来。未来,中国需要在国际抗疫合作中不断以更高水平的改革开放来推动高质量发展,继续引领再全球化拓展进步,为全球化带来新的生机与活力。
