LED節(jié)能燈報(bào)價(jià)之辨認(rèn)LED的竅門，首要就是在以下的幾個(gè)方面進(jìn)行選購(gòu)。
LED energy-saving lamps offer recognition LED trick, is the first in the following several aspects of the purchase.
一看包裝和商標(biāo)
A look at the packaging and trademarks
國(guó)家強(qiáng)迫需求LED燈具出產(chǎn)廠家商品在外包裝上標(biāo)出以下內(nèi)容：額外電壓、電壓規(guī)模、額外功率、額外頻率。一般說(shuō)來(lái)，優(yōu)質(zhì)商品的商標(biāo)打印質(zhì)量好，字體明晰，不易掉落，用軟濕布擦洗，象征明晰可辨，不易擦掉，有出產(chǎn)廠家的商標(biāo)及有關(guān)認(rèn)證象征。偽劣商品打印質(zhì)量差，字體含糊，易擦除，無(wú)出產(chǎn)廠家的商標(biāo)及有關(guān)認(rèn)證象征。
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燈管外觀
Two see the LED lamp appearance
真實(shí)的LED節(jié)能燈，是用三基色管，管白，用手遮住看，更白。別的，從燈管上看，可把多只燈放在一同對(duì)比，燈管形狀和尺度一致性較好的多為機(jī)器彎折成型，多是大規(guī)模出產(chǎn)的商品。商品的一致性好，質(zhì)量較簡(jiǎn)單得到確保，修理時(shí)的互換性較佳。當(dāng)然，外觀上還不能有裂縫、松動(dòng)和接口間被撬過(guò)的痕跡。在裝置、拆開(kāi)過(guò)程中，燈頭不該有松動(dòng)，歪頭表象。
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.
三看作業(yè)時(shí)的溫度
Three see operation temperature
LED節(jié)能燈在正常作業(yè)狀態(tài)下，其溫升應(yīng)很低。不然，LED節(jié)能燈壽數(shù)很短。一起，節(jié)能燈點(diǎn)亮?xí)r，有很快的閃爍，要么很扎眼動(dòng)搖，都闡明該節(jié)能燈存在質(zhì)量問(wèn)題。
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.
四看發(fā)動(dòng)功能
Four see launch function
LED節(jié)能燈發(fā)動(dòng)有兩個(gè)特性：一是溫度越高發(fā)動(dòng)越簡(jiǎn)單；二是燈關(guān)掉，不會(huì)閃。別的，值得一提的是，不少LED節(jié)能燈一開(kāi)很暗，這對(duì)燈泡壽數(shù)晦氣，LED節(jié)能燈應(yīng)在其內(nèi)部設(shè)有電源電路和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.
五看攪擾狀況
Five see troubling situation
在中國(guó)，電磁兼容性已是電器有必要經(jīng)過(guò)的項(xiàng)目，但是，此項(xiàng)目檢測(cè)很雜亂，用戶購(gòu)燈時(shí)一看包裝上是不是有經(jīng)過(guò)國(guó)家電磁兼容性測(cè)驗(yàn)的象征，二是帶一個(gè)中短波收音機(jī)，當(dāng)燈作業(yè)時(shí)，把收音機(jī)置于鄰近，收音要中短波無(wú)電臺(tái)處宣布的噪音越低，被測(cè)燈的電磁兼容性就越好。
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.
