节能灯的主要发光材料仍然是钨丝。其原理是,钨丝通电发热后会产生电子,运用一定的技术手段,使电子加速。节能灯的灯管被设计成真空,其中充有水银,即汞。加速后的电子与受蒸发后的汞原子作用,产生紫外线光在节能灯管内涂有荧光物质,紫外线光照射到荧光物质上,就产生了光线。LED是发光二极管的英文缩写。LED灯的主要部件是一个能将电能转化成光能的半导体,用银质电线或者金质电线将其与电路板连接,同时周围用户氧树脂密封保护,将上述整体置于保护壳之中。LED灯与节能灯除了发光原理上的不同,在环保节能、使用寿命、稳定度方面也是有着十分显著的不同。与节能灯相比,LED更加节能。LED消耗的能源是节能灯的百分之二十五,这是因为普通节能灯仍然消耗一部分的电能转化为热能,而LED灯则没有这个问题。LED灯的使用寿命更长,质量合格的LED灯泡的使用寿命可以达到一万至两万小时,而同样的节能灯,其使用寿命在六千到一万小时之间。LED灯更加环保。汞对于节能灯来说是必不可少的发光材料之一,随着使用时间增长,节能灯的密封性会出现缝隙,其中的汞会挥发至空气之中,对空气造成污染。LED灯完全没有这方面的问题,使用安全环保。LED灯在抗震防雷性能上要远远超过节能灯泡。电压不稳定导致的连续开关对LED灯的影响要远远小于节能灯。而节能灯若频繁开关,使用寿命会大大降低。目前造成LED推广阻碍的一个重要原因就是价格普遍太贵,对于普通用户来说,使用寿命、节能环保这些性能毕竟不能被直观观察到,能被直观感受到的只有价格。但是综合考虑上述LED灯的优势,它安装时的费用也是可以接受的,使用寿命毕竟有那么长,而且稳定不易坏,从长远来说,绝对比买节能灯划算多了。随着家庭装修热的不断升温,吸顶灯的变化也日新月异,不再局限于从前的单灯,而向多样化发展,既吸取了吊灯的豪华与气派,又采用了吸顶式的安装方式,避免了较矮的房间不能装大型豪华灯饰的缺陷。LED吸顶灯的灯体直接安装在房顶上,适合作整体照明用,通常用于客厅和卧室。LED吸顶灯在安装和使用中应注意以下几点:
在砖石结构中安装吸顶灯时,应采用预埋螺栓,或用膨胀螺栓、尼龙塞或塑料塞固定;不可使用木楔。并且上述固定件的承载能力应与吸顶灯的重量相匹配。以确保吸顶灯固定牢固、可靠,并可延长其使用寿命。
当采用膨胀螺栓固定时,应按产品的技术要求选择螺栓规格,其钻孔直径和埋设深度要与螺栓规格相符。
固定灯座螺栓的数量不应少于灯具底座上的固定孔数,且螺栓直径应与孔径相配;底座上无固定安装孔的灯具(安装时自行打孔),每个灯具用于固定的螺栓或螺钉不应少于2个,且灯具的重心要与螺栓或螺钉的重心相吻合;只有当绝缘台的直径在75mm及以下时,才可采用1个螺栓或螺钉固定。
LED吸顶灯不可直接安装在可燃的物件上,有的家庭为了美观用油漆后的三夹板衬在吸顶灯的背后,实际上这很危险,必须采取隔热措施;如果灯具表面高温部位靠近可燃物时,也要采取隔热或散热措施。
