YCPWK移动橡套抗拉电缆

选择照明光源应考虑到各种光源的优缺点，适用场所、额定电压以及照度（照明亮度）的需要等方面的要求。在前面的课程中，我们对白炽灯、碘钨灯、日光灯等灯具的特点都有所了解，每种灯具的特点不同其光源的表现也各异，为了便于比较，现将常用的几种光源列表说明其优缺点及适用场所：

The selection of lighting source should take into account the advantages and disadvantages of various light sources, the requirements of applicable place, rated voltage and illumination (lighting brightness). In the previous course, we h***e known the characteristics of incandescent lamp, iodine tungsten lamp, fluorescent lamp and other lamps. Each lamp has different characteristics and its light source performance is also different. In order to facilitate comparison, we will list the advantages and disadvantages of several commonly used light sources and their applicable places:
