不久前,诺贝尔物理学奖颁发给3位日本科学家。他们在发现新型高效、环境友好型光源,即蓝色发光二极管(LED)方面做出了巨大贡献。虽然LED灯在使用寿命、发光效率和环保等方面有很大优势,但是目前传统日光灯的使用范围仍然很广泛。日光灯优点有很多,但存在一些问题,如汞污染。日光灯、节能灯等又称荧光灯,具有发光面积大、效率高、省电、光线柔和、使用寿命长等优点,广泛使用于家庭、学校、办公室等室内环境。

Not long ago, the Nobel Prize in Physics was awarded to three Japanese scientists. They made a significant contribution to the discovery of a new, highly efficient, environmentally friendly light source, the Blue Light Emitting Diode (LED). Although the LED lamp has great advantages in terms of service life, luminous efficiency and environmental protection, the use range of the traditional fluorescent lamp is still very wide. There are many advantages of fluorescent lamps, but there are some problems, such as mercury pollution. Fluorescent lamps, energy-saving lamps, also known as fluorescent lamps, with light-emitting area, high efficiency, power saving, soft light, long life, etc., widely used in homes, schools, offices and other indoor environments.
