摘要： An LED illumination system includes a DC power supply, at least two LED illumination lamp sets and at least two power circuits corresponding to the LED illumination lamp sets. The DC power supply provides sufficient electric power for the LED illumination lamp sets and is connected to the LED illumination lamp sets via the power circuits. The invention supplies electric power required by the LED illumination lamp sets via a single DC power supply without an extra DC power supply, hence the cost is lower. Moreover, the DC power supply is located remote from the LED illumination lamp sets, hence high temperature generated by the DC power supply does not affect lighting and lifespan of the LED illumination lamp sets. The hazard of electric shock by inadvertently touching the AC power source while replacing lamps in the LED illumination lamp sets can also be avoided to improve safety.

摘要翻译： LED照明系统包括DC电源，至少两个LED照明灯组和至少两个对应于LED照明灯组的电源电路。 直流电源为LED照明灯组提供足够的电力，并通过电源电路连接到LED照明灯组。 本发明通过单个直流电源提供LED照明灯组所需的电力，而不需要额外的直流电源，因此成本较低。 此外，直流电源远离LED照明灯具，因此由直流电源产生的高温不会影响LED照明灯具的照明和寿命。 也可以避免在更换LED照明灯组时更换灯泡时无意中触碰交流电源的触电危险，从而提高安全性。
