摘要
目前的LED路灯主要是由市电供电,也有利用风能或太阳能等配合蓄电池供电的,但蓄电池需要反复充放电,会影响使用寿命。通常采用一颗LED芯片照亮道路中某一特定区域,一旦其中部分芯片损坏,易导致照明盲区,一般没有备用芯片,维修不便。为了克服上述不足,在此提出一种新型LED路灯,由各种能源(风能、太阳能及振动能)配合市电供电,节余部分并网进入市电系统,不足部分由市电系统进行补充。蓄电池作为应急之用,充放电频率比较低,可延长使用寿命。每个LED芯片上均设置自由曲面透镜,使其发出的光都能均匀照射到路面特定的矩形区域,其中部分芯片损坏时不会造成照明盲区,只需设置部分备用芯片,便于维修。实际测试表明,系统使用效果良好。
The available LED street lamps are mainly powered by the mains supply,and also powered by wind energy or solar energy cooperated with battery. The service life of the storage battery is influenced by charging and discharging repeatedly.Usually one LED chip is used to illuminate a certain particular area. In case that some of the chips are damaged,it is easy to lead to lighting blind area. The maintenance is inconvenient without spare chips. In order to overcome the above disadvantages,a new LED street lamp is put forward,which utilizes various energy（wind,solar and vibration energy） cooperated with the mains power supply. On the one hand the surplus energy enters into the mains supply,on the other hand the insufficient energy is supplemented by the electric supply system. The storage battery is used as an emergency device,so its service life is prolonged due to the low charge-discharge frequency. The free-form surface lens is installed in each LED chip,which makes its light illuminate a specific rectangular area of the road surface evenly. Therefore,the damage of some chips will not result in the appearance of lighting blind area. Some spare chips are needed for preparation only prepared to make maintenance convenient.The real test indicates that the application eppect is all righy.
