太阳能路灯的中心组件：
The main components of solar street lights
1.首要有电池板，操控器，电池 ，光源，灯杆构成
Solar panel , controller, led lamp, pole ect.
2.作业原理是白日经过太阳能电池板给蓄电池充电，黑夜使用蓄电池给光源供电。
Absorb the sunlight at day and charge the battery and power the led lamp at night.
现在太阳能路灯的光源首要以LED为主，为了确保LED光源 的寿数，LED光源通常需求一个恒流源。大多数太阳能路灯操控器经过集成的方式将恒流源内置在操控器内部为光源供电。
The popular street lights is popular with Led power source, and which require a DC supply. Most of the solar street lights are controlled by controller,
所以一般的太阳能路灯操控器的首要作 用即是维护电池，操控和驱动光源。 市电互补太阳能路灯跟传统太阳能的差异在于，市电互补太阳能路灯需求接一组市电电缆到操控器上，在电池缺电的情况下变换市电供电。
The normal solar street lights controller is to protect the battery, led lamp ect.
The difference between the traditional solar energy and the solar energy complementary solar street lamp is that the city electricity complementary solar street lamp needs to connect a group of electric power cable to the controller, and the power supply is converted to the power supply when the battery is short of power.
两种体系各有优劣势：
The different advantages of two different system
传统的太阳能路灯首要长处在于：
The traditonal solar street lights with advantages
1.不必铺设电缆线，装置便利。
NO Cable need, installation is simple
2.操控器恒流一体，构造简略。
DC control and simple structure
3.所有动力自给自足，无需其它动力弥补。
All power are self supply , no need other addtional power.
缺陷在于:
The disadvantages
1.若需求要大功率光源或许习惯特别环境，如阴雨天较多，就需求加大电池板
及蓄电池，成本较高。
If you need to high-power light source or adapt to special circumstances, such as rainy days more, you need to increase the battery board
And battery, high cost.
2.环境习惯能力较差
Poor environmental adaptability
市电互补太阳能路灯首要长处在于：
The main advantage of complementary solar street lamp
1.光源可做较大功率
High power available
2.受环境影响较小
Strong environmental adaptability
3.对电池，电池板请求不高
No high requirement for battery , solar panel
缺陷在于：
The disvantages
1.需铺设线缆，装置较为费事
Need cable and complicated installation
2.需求装备别的的开关电源及恒流源
Additional switching power supply and constant current source are required
