减少照明消耗

出于经济因素和环保考虑,全世界都在关注如何减少能耗。在家庭和商业楼宇中,照明在全部耗电量中的占比分别是25%和21%。所以,如何减少照明耗电量是业界关注的一大焦点。

随着卤素灯和紧凑型荧光灯的出现,人类在减少能耗方面取得了一定的进步。

虽然有很多人一直致力于在未来几年内逐步淘汰高耗电的白炽灯,不过卤素灯和紧凑型荧光灯等现有替代品仍存在健康风险和光质减弱等不足。与白炽灯、卤素灯和紧凑型荧光灯这些旧有技术相比,LED技术这几年在节能方面的效果更显著。此外,LED技术在改善效率、功率因数和光质方面的表现也非常明显。因此,LED技术被定位为未来几十年内的技术首选。据业内分析师估计,如果全球LED照明的普及率在2020年底达到50%,那么2020-2030年的节约下来的能源总额将超过4890亿美元。
