电源为什么要使用80%的功率
①电源自启动本身会有功率损耗。
②布线接户外灯具会有线损，通常1米/1w。
③长时间带载，温度升高产生功率损耗。
④留出20%旷量使用，能让电源更稳定，使用寿命更长。
Why  the power supply use 80% of the total  power?
①The self-starting of the power supply will cause power loss.
②There will be wire loss when wiring connected to  lamps, usually 1m/1w.
③ Long-term load, the temperature rises, resulting in power loss.
④ Set aside 20% of the open capacity for use, which can make the power
