 led线条灯即led洗墙灯系列铝型材灯体,紧凑轻巧端盖和安装支架由铝合金高压压铸耐高温硅橡胶密封圈,保证防水的可靠性。灯具可单个或多个组合安装。适用于各种建筑物,室内外局部或轮廓照明

防硫化就是其中一个重要工艺,对芯片厂家的技术和设备要求较高。经过防硫化处理的灯珠,才更适合户外LED线条灯使用。因为LED线条灯的灌封胶或者线路板,多多少少会有硫或者其他元素成分,再加上户外环境存在大量腐蚀成分,对线条灯灯珠影响很大。


在遇到下雨或者下雪的时候加上关灯休息时,led线条灯体内的气温会急剧下降,温度急剧下降会导致灯壳内部瞬间产生压力甚至更大的真空。这时,空气或者湿气会通过密封间隙偷偷进入灯体内凝结成水珠,一旦密封的灯体内产生水珠,就不容易被排出来。长期排不出的水珠会在灯体内腐蚀电子元器件,严重影响led线条灯的寿命。

如果不需考虑驱动和电源出现的故障问题,大功率led线条灯的寿命长短的一个表现就是:“光衰”,意思就是,使用的时间越长它的亮度就越低,直到寿命耗尽灭灯。
 led线条灯通常采用铝材做散热器,散热器与空气的接触面积越大越好,这样有利于散热,整灯工作稳定,光衰小寿命长;球泡和天花射灯不要有过大的透气孔,以免在使用过程中蚊虫爬入,影响照明效果或造成不必要的损坏。

灌胶问题,玻璃面下面的硅胶要稠一点好,太稀的话影响凝固效果;其次,很多人问盖玻璃时要怎样,因为力道的不同,压在玻璃下面的硅胶量也不同,这里我们要求的是压紧一点;还有是关于防水透气阀的问题,一些高档的款式会用上,防水透气阀的原理是防止水进入而空气可以进入,这在雨天,led线条灯在雨水的急速降温时,防水透气阀能够加快促使灯体内外温度一致,使压强变化不会太剧烈,避免破坏灯体内部元件,平时也有利于散热,加快空气对流。就这几点,做得好的led线条灯轻松能达到IP65以上的效果。

优质的led线条灯光色必然是一样的,不会出现黄光或者其他的光色出现。如果大家不懂如何分辨,可以教大家一个小方法,只有将这一些电灯点亮,观察它们的光色变化就可以得到想要的答案了。由于led线条灯的亮度高,两种品牌同类型的灯,在同等条件下,用眼睛直视的方法观察进行比较,是很难判断其亮度的高低,同时这样也容易伤害眼睛视力。通常我们建议用一张白纸将光源盖住,通过白纸对光的衰减后,再进行比较,这样就比较容易看出灯光的亮度差异,亮度越高的就越好。
