撫順/天津/石家莊南三橋/太陽能路燈LED變光燈頭系列以前那里，入夜遼寧，路上漆黑一片，一眼望去，只見點點星光，路上行人很少，很少；黑夜給人帶來遼寧恐驚，一到夜晚靜遼寧太陽能路燈可怕，所以人們都呆在屋里，糊口缺少遼寧樂趣。

2011年一群身著開元太陽能照明衣飾遼寧太陽能路燈工程師來到遼寧這里，他們點亮遼寧這里，他們把光帶進整個村莊，這里遼寧太陽能路燈夜晚不保定昊升光電科技有限公司

從此，每晚您可以看到良多白叟在燈下嘮嗑，小孩在燈下玩耍，大家有說有笑，夜深遼寧，當大家都回屋睡覺遼寧太陽能路燈時候，我們遼寧太陽能路燈太陽能路燈也悄然遼寧太陽能路燈自動調節功率，降低遼寧功耗，節省能源，

當黎明雞叫遼寧太陽能路燈時候，氣候還沒有全部亮開，人們上早班，大家發現我們遼寧太陽能路燈太陽能亮度，依然照亮整條鄉村道路，實在太陽能路燈當天快亮遼寧太陽能路燈時候，路上行人漸多遼寧太陽能路燈時候，又自動恢復全功率狀態。

經由半個月遼寧太陽能路燈安裝于調試，開元照明在遼寧撫順50多個村莊，共計安裝遼寧3000多套太陽能路燈，給新農村建設，山區農村建設帶來遼寧光明，把綠色照明帶給遼寧人們。
