选购LED手电筒的5个注意事项

1、头数适中。家用的一般不要超过12头,使用的电池在2~3颗比较好,再大了有点浪费,用于其他特殊需要的可根据需要自己确定。
2、焊接要牢。每只二极体都是通过焊接连接在线路板上的,如果有虚焊接触不好,就有可能造成不亮或影响整体使用。

3、电珠聚光面儘量集中一点。这种手电筒不像普通电筒可以调整焦距,选购时应注意不要有散光现象。

4、电源开关接触要明显。这种手电筒多采用旋转式开关,拧紧就开,再拧松就关,如果接触不明显,很容易造成时亮时灭的现象。

5、注意防水。由于它属于电子产品,手电筒前部有一块线路板,一旦进水容易发生短路,造成损坏。

为何要选用LED手电筒,不好意思又得介绍一下LED的优点了:

1、LED超长使用寿命,一般可达到5万小时以上比传统钨丝灯寿命高出5~10倍。
2、冷光,发热度低,不会损坏灯座安全性高。
3、反应速度快,耐冲撞、体积小、易小型轻量化等。
4、省电、节能,新环保灯泡。
5、反应速度快只要1us(微秒),不需暖灯可提高安全度。
6、低压驱动安全。
