LED日光灯如何选择?

摘要

现在市场上生产LED日光灯的企业不计其数、产品品质与性能差异很大,这让不懂行的外贸企业、节能公司、工程公司、外资企业驻中国采购办等非专业人员在采购产品的过程中不知怎样去辨别各企业生产的LED日光灯的质量与性能,在选购产品时不知所从,可能花了高的价格而没有买到自己想要的理想产品。

一、型材、结构。

2、半塑半铝管:现在市场上所销售的LED日光灯基本上都是这种一半PC一半铝合金,在需要透光的那一半采用塑料,在不需要博客来棋牌透光而需要散热的那一半就采用铝合金。电源当然是放在铝管里面,这样,LED的发热量再加上电源的发热量就相当大了,因为这种灯的功率通常在20W左右。功率再做大点,半根铝管并不能解决它的散热问题。所以又提出另一种散热的铝管结构:扇骨形铝管。扇骨形铝管采用扇骨形状的散热结构,大大增加了散热器面积。它把电源放到管外,从而可以把半边铝壳完全做成散热器。相对于半圆形的铝管来说,它的散热面积至少增大了3倍以上。再加上电源不放在管内,又可以减少热量,这就大大延长了LED的寿命。(图片放不进去,请见谅)


二、电源


LED日光灯的电源分为内置式和外置式两种。所谓内置式就是指电源可以放在灯管内部。这种内置式的最大优点就是可以做成直接替换现有的荧光灯管,而无需作任何电路改动。所以内置式的形状都是做成长条形,以便塞进半圆形的灯管中去。

三、芯片


这个基本上就没有什么好说的,一般情况下,像CREE、Osram博客来棋牌、惠普(HP),日亚化学(Nichia),丰田合成Lumileds等一线品牌的品质肯定要比二线或台湾的要好。目前用在日光灯的是3528、3020、3014等规格,这几种规格主要是其大小尺寸、芯片的散热方式不一样。同一品牌的芯片,封装的厂家不一样,其品质也不一样。
