1879年,爱迪生发明的白炽灯结束了人类“黑暗”历史,为人类文明的发展做出了重要贡献。随着人类对能源的深层认知和对能源节约的重视,以汞蒸汽放电产生紫外线照射荧光粉而发光的气体照明有力地促进了人类照明技术的进步。但因为汞蒸汽有毒,使用寿命短,并含有害人体的紫外线,于是人类对健康、节能、环保的新型绿色光源产品充满期待和渴求。LED作为一种新型的绿色光源产品,其节能化、健康化、艺术化的特点,成为城市照明的一大亮点。LED灯替代传统光源照明,也是未来的发展趋势。经过多年的不懈努力,
In 1879, Edison invented the incandescent lamp to end the history of mankind ’darkness’ and made an important contribution to the development of human civilization. With the human’s deep cognition of energy and the emphasis on energy saving, the gas lighting which glows by irradiating the mercury with a mercury lamp to emit ultraviolet light and irradiating the phosphor effectively promotes the progress of human lighting technology. However, because mercury vapor is toxic, has a short service life and contains harmful UV rays, human beings are full of expectation and desire for a new green light source product that is health, energy saving and environmental protection. LED as a new type of green light source products, its energy-saving, health, artistic features, become a bright spot in urban lighting. LED light alternative to traditional lighting, but also the future trend of development. After years of unremitting efforts,
