摘　　要：以LED为代表的数字化照明时代,是继爱迪生发明灯泡以后的又一次照明革命,因为之前的人工照明都是连续的光谱,是模拟信号,如同传统的胶卷。而如今的LED,是数字化设备,光谱是不连续的,而且在使用中无法把灯具和光源划分开来。灯具的研发和生产,必须具有系统化的思维和方法,从光学系统、LED模组、电源系统、热学管理、灯具等各方面系统开发。Era represented by the LED digital lighting,the scientific community have a saying is the Edison invent the light bulb again after the revolution of lighting,because before the artificial lighting is a continuous spectrum,are analog signals,as the traditional film now LED,digital equipment,spectrum is discrete,and not in use the lamps and lanterns and light so divided the development and production of lamps and lanterns,must have a systematic thinking and method,the LED module,power supply system from the optical system of lamps and lanterns of thermal management system and so on various aspects of system development.
