额定功率（瓦数和盏数）的确定：为了满足生产、工作、学习和生活的需要，不同照明场所，需要不同的照度。在要求不太严格的场所，可按单位面积所需要的照明功率计算，先计算整个场所所需要的照明功率，然后再来确定每盏灯的功率和盏数。用公式表示如下：

Determination of rated power (wattage and number of lamps): in order to meet the needs of production, work, study and life, different lighting places need different illuminance. In places with less strict requirements, the lighting power required per unit area can be calculated. First, the lighting power required for the whole place can be calculated, and then the power and number of each lamp can be determined. The formula is as follows:

∑P=WS

∑P=WS

式中∑P为场所所需要的总照明功率，单位为瓦特。W为单位面积所需要的照明功率，YCB扁电缆单位为瓦特/平方米，单位面积照明功率可参考下表。S为整个照明场所的面积，单位为米2。场所所需要的总照明功率∑P算出后，可根据场所的情况确定安装电灯的盏数N，然后可按下式计算每盏灯的功率P：ycb扁电缆

Where ∑ P is the total lighting power required by the place, in watts. W is the lighting power required per unit area, in watts per square meter. Refer to the table below for the lighting power per unit area. S is the area of the whole lighting place, in M2. After the total lighting power ∑ P required by the place is calculated, the number of electric lamps n can be determined according to the situation of the place, and then the power P of each lamp can be calculated according to the following formula:
