简约原则
The principle of simplicity
灯饰在房间中应起到画龙点睛的作用。过于复杂的造型、过于繁杂的花色，均不适宜设计简洁的房间。
Lighting should play a key role in the room. Too complicated modeling, too complicated color, are not suitable for the design of a simple room.

方便原则
Principle of convenience
大部分人都经历过更换吸顶灯灯泡的尴尬：踩着桌子、踏着椅子、昂首90度，抬双臂过头到2。5米高甚至更高的顶棚。选择灯具时，一定要考虑更换灯泡方便。

A 5 meter high or even higher roof. When choosing lamps, you must consider replacing bulbs.


节能原则
Energy saving principle
节能灯泡节电、照明度又好，也不会散发过多热量，适用多头灯具。节能灯泡大都是标准螺口，而吊灯有两种口径，一种是标准的，可以使用节能灯泡；一种是非标准的，不能使用节能灯泡。选择时要注意：射灯大都是非节能产品。
The energy saving lamp has good electricity saving and good illumination, and it does not emit excessive heat. Most of the energy saving bulbs are standard snails, and the chandeliers have two kinds of caliber, one is standard, and energy saving bulbs can be used; the other is non - standard, and energy saving light bulbs can not be used. Attention should be paid when choosing: spotlights are mostly non energy saving products.

安全原则
Safety principle
一定要选择正规厂家的灯具。正规产品都标有总负荷，根据总负荷，可以确定使用多少瓦数的灯泡，尤其对于多头吊灯最为重要，即：头数×每只灯泡的瓦数＝总负荷。另外潮气大的卫生间、厨房应选用防水灯具。
Must choose the regular manufacturer of lamps and lanterns. Regular products are marked with total load. According to the total load, how many watts of light bulbs can be used, especially for multi head chandeliers, that is, the number of heads and the number of tiles per bulb = total load. In addition, the bathroom with large humidity and kitchen should choose waterproof lamps and lanterns.


功能原则
Functional principles
不同使用功能的房间，应安装不同款式、照明度的灯饰。客厅应该选用明亮、富丽的灯具；卧室应选用使人躺在床上不觉刺眼的灯具；儿童房应选用色彩艳丽、款式富于变化的灯具；卫生间应选用式样简洁的防水灯具；厨房应选择便于擦拭、清洁的灯具；某些需要特殊表现的地方也可选择地暖地板射灯。
Different types of lighting should be installed in rooms with different functions.
