装饰用led灯要如何选购

若是家里，用的也不是很多选择单色的(白色、**)等；选择并联灯；实在不懂就选择一些品牌灯具质量会好一些而且会包换保修...
灯带不长的话,也可选T5D灯管(不要选T4)

ぁ念念不忘 07-06 05:36

1、LED射灯采用的芯片：芯片有国产和台湾芯片，进口芯片。芯片不同，价格差异很大。进口芯片价格比较昂贵，在国内市场很少人用，那种主要是针对高端客户。目前的中端客户一般选用的是台湾芯片，性价比是最好的。

2、LED射灯封装：分树脂封装和硅胶封装。树脂封装的价格要便宜一些，因为散热性能稍差，其他都是一样。硅胶封装的散热性能好，因此价格要比树脂封装的稍贵一点。

3、LED射灯颜色的一致性：目前国内有很多封装厂，大大小小加起来也有上千家，当然也就有实力的强弱之分。有很多小的封装厂由于没有分光分色机，因此要么不分光分色，要么就是外发。这样对于品质就很难保证。

4、LED的亮度：不同亮度的LED价格不同，普通亮度和高亮的LED价格相差比较悬殊。因此，采购的时候一定要清楚的知道自己需要的是什么样的亮度，这样才能准确的定位自己的产品。

希望可以帮助到你。

Led射灯分低压、高压两种，消费者最好选低压射灯，其寿命长一些，光效高一些。射灯的光效高低以功率因数体现，功率因数越大光效越好，普通射灯的功率因数在0.5左右，价格便宜，优质射灯的功率因数能达到0.99，价格稍贵。
射灯一般用于对装饰物的加强照明上，一般是嵌入到吊顶或墙体中，射灯工作时一般会发出较高温度，所以一定要购买优质的产品，不然会有安全隐患。
射灯使用时要搭配变压器使用，灯珠也应选择品质好的，不然射灯的灯珠很容易坏，想想，吊顶里的射灯灯珠，更换起来可是相当麻烦的。
而目前市场上的射灯质量良莠不齐，凭肉眼很难辨别好坏，所以购买射灯最好选择品牌产品，并选择相搭配的优质变压器。
