在你的院子里安装重点照明和安全照明不需要电工和大量昂贵的劳动力。低电压照明系统使得无需专业人员即可轻松规划和安装庭院灯。

为什么要用低压灯取代传统的120伏家用电源？低压灯运行成本更低，安装成本更低，操作更安全。例如，如果你用一把花园铁锹碰到低压系统的电线，你手上最担心的就是修理电线，而不是去急诊室。

《读者文摘》有一个关于规划和安装大型低压系统的分步指南。其中包括改进更便宜灯具设计的技巧，以及各种可以为您省钱和头痛的想法：

• Buy a larger transformer than you'll initially need so you can add lights later as your landscape (and imagination) expands. If you'll be installing 400 watts of lights, buy a 600-watt transformer.
• The farther a light is from the transformer (and the more lights installed between it and the transformer), the less light it will put out. Avoid this "voltage drop" by creating a tee (Fig. A ) and running two short lines rather than one long one. A good rule of thumb is to put no more than 100 watts of lighting on one line. If you want to put ten 20-watt lights on a circuit, make a tee connection with five lights on one line and five on the other. You can also minimize voltage drop by using a thicker gauge wire.

安装一个低压系统并不像买一盒太阳能灯并把木桩塞进花园小路那么简单，但最终的结果是一个具有更均匀、更可靠照明的优质照明系统。
