LED节能灯报价之辨认LED的窍门，首要就是在以下的几个方面进行选购。
LED energy-saving lamps offer recognition LED trick, is the first in the following several aspects of the purchase.
一看包装和商标
A look at the packaging and trademarks
国家强迫需求LED灯具出产厂家商品在外包装上标出以下内容：额外电压、电压规模、额外功率、额外频率。一般说来，优质商品的商标打印质量好，字体明晰，不易掉落，用软湿布擦洗，象征明晰可辨，不易擦掉，有出产厂家的商标及有关认证象征。伪劣商品打印质量差，字体含糊，易擦除，无出产厂家的商标及有关认证象征。
Countries forced demand LED lamp manufacturers of goods marked with the following on the outer packing: extra voltage, voltage, power, frequency scale extra extra. Generally speaking, the trademark printing quality goods, font clear, not easy to fall off, with a soft damp cloth to scrub, symbolic legible, not easy to erase, a manufacturer of trademarks and relevant certification symbol. Fake and inferior commodities poor print quality, fonts vague, easy to erase, no manufacturers and the relevant certification trademark symbol.
二看LED灯管外观
Two see the LED lamp appearance
真实的LED节能灯，是用三基色管，管白，用手遮住看，更白。别的，从灯管上看，可把多只灯放在一同对比，灯管形状和尺度一致性较好的多为机器弯折成型，多是大规模出产的商品。商品的一致性好，质量较简单得到确保，修理时的互换性较佳。当然，外观上还不能有裂缝、松动和接口间被撬过的痕迹。在装置、拆开过程中，灯头不该有松动，歪头表象。
LED energy saving lamp is real, with three tubes, tube white, his hand to see, more white. The other, from the lamp, the lamp can be put together contrast, tube shape and scale better consistency for the machine bending forming, are mass produced goods. The consistency of product is of better quality, simpler ensured, repair interchangeability better. Of course, the appearance can not have cracks, loose and the interface between the traces of broken. In the device, open process, the lamp should not loose, Waitoushan representation.
三看作业时的温度
Three see operation temperature
LED节能灯在正常作业状态下，其温升应很低。不然，LED节能灯寿数很短。一起，节能灯点亮时，有很快的闪烁，要么很扎眼动摇，都阐明该节能灯存在质量问题。
LED energy-saving lamps in the normal working state, the temperature rise should be low. Otherwise, LED energy-saving lamp life is short. Together, the energy-saving lamp is lit, flash quickly, or very glaring shake, all the energy-saving lamps quality problems.
四看发动功能
Four see launch function
LED节能灯发动有两个特性：一是温度越高发动越简单；二是灯关掉，不会闪。别的，值得一提的是，不少LED节能灯一开很暗，这对灯泡寿数晦气，LED节能灯应在其内部设有电源电路和PCB板子。
LED energy saving lamp engine has two characteristics: one is the higher the temperature to launch more simple; two is light, no flash. The other, it is worth mentioning that, many LED energy saving lamp a very dark, the light bulb life bad luck, LED energy-saving lamps should be internally provided with a power supply circuit and PCB board.
五看搅扰状况
Five see troubling situation
在中国，电磁兼容性已是电器有必要经过的项目，但是，此项目检测很杂乱，用户购灯时一看包装上是不是有经过国家电磁兼容性测验的象征，二是带一个中短波收音机，当灯作业时，把收音机置于邻近，收音要中短波无电台处宣布的噪音越低，被测灯的电磁兼容性就越好。
In China, the electromagnetic compatibility is appliances necessary after project, however, this test is very messy, users purchase lights at the packaging is it right? Has been a symbol of national electromagnetic compatibility test, the two with a short wave radio, when the lamp is in operation, the radio in the neighborhood, to medium and short wave radio no radio announced that noise is low, the electromagnetic compatibility test lamp is better.
