能效很高污染减少 太阳能路灯前景光明

来源:照明中国网

夜幕降临,宁波工程学院镇海新校区的河边,一盏盏草坪灯在绿化带中依次点亮,还不时变幻出红、黄、绿等颜色,煞是好看。新鲜的是,连同学校学生餐厅两侧40盏两层多楼高的路灯,都是不用电,而靠太阳能来发光的。

  研发太阳能灯的项目负责人,工程学院电信学院王洪涛教授自豪地说,规模化布设太阳能灯,在宁波还是头一次。

  镇海新校区的这批太阳能灯,分为300盏0.6米高的草坪灯和40盏6米高的路灯两种,本月6日正式安装调试起用。五彩灯光倒映在水中,学生们看了都说:实在太美了。

  太阳能灯的奥秘在于其顶部有一块太阳能接收板,内藏蓄电池,用芯片自动控制灯的开关。王教授用一本书盖住草坪灯的太阳能接收板,很快LED灯管就亮起来了,“阳光照射一天,太阳能灯可照明7天以上,能效很高。”

  据记者了解,这种太阳能LED灯是工程学院电信学院老师联合国内几所高校研制出来的,在学院的帮助下,老师们还成立了一家新能源公司,实现“产、学、研”一条龙。学院大四的杨超一同学已经是公司的员工,成了技术能手。王教授介绍说,去年,她们的太阳能照明系统上报了7项国家专利,其中两项已经获批,另外两项初审已通过。

  与普通的路灯相比,太阳能灯不用电,无需挖沟埋电线,安装“就像种萝卜,挖个坑放进去就可以了。”王教授说,镇海新校区的340盏灯,电压分别是4伏和12伏的直流电,不会触电,十分安全。

  太阳能灯发光很“给力”,30瓦的LED灯管亮度相当于100瓦的普通路灯。因为不用电,它更是节能减排的“高手”。王教授说,100套普通的300W市政道路照明路灯,以每天10小时照明计,使用10年要耗电100万度以上,换算成二氧化碳排放量,有1078吨。而有了太阳能灯,就全省了。

  根据王教授的测算,镇海新校区的340盏大小太阳能灯,一年省下的二氧化碳排放量,有70吨之多。

  虽然初期投入,太阳能灯比普通路灯费用要大一点,但若10年用下来,总费用能省30%至50%,还能减少能源污染。
