 跟著LED紅外燈的廣泛應用，其質量問題也逐步遭到關注。因為裝置紅外燈的紅外攝像機絕大多數在高處，一旦出現問題，替換較為費事。所以紅外燈的質量的區別就顯得十分重要。在此將一些簡略的辨別辦法談談，僅供咱們參閱。
With the wide application of LED infrared light, the quality problem is gradually attention. Because most of the infrared lamp infrared camera device on high, if there are problems, replace more trouble. So the difference of infrared light quality is very important. Here are some brief ways of distinguishing, for our reference only.

怎么辨別紅外燈的質量好壞竅門一.正芯和散芯的區別
How to identify the quality of tips. A lamp distinction is core and core powder
燈芯選用正芯仍是散芯決議著紅外燈的質量，二者之間的報價也十分懸殊，乃至相差五倍以上，這也是商場上紅外燈報價三六九等的一個重要原因。攝像機對發光光譜在850納米的燈最敏感，即有紅爆的紅外管，這個頻段的紅外燈管也是報價最貴的。將紅外燈的燈板取下，再找一只可調的穩壓電源。在光線較暗的環境下，先將穩壓電源的輸出電壓調至紅外燈的額外作業電壓，銜接紅外燈，此刻紅外燈正常作業，然后逐步調低電壓至燈管熄滅，看燈管的發光程度是不是共同，假如在此過程中燈板上一切的燈管發光相同，則闡明燈管用的是正芯;假如有的燈稍亮有的燈稍暗，那么燈芯的質量就讓人置疑了。別的還有一種辦法——丈量法。在紅外燈正常作業的情況下丈量每個燈管的作業電壓。如今商場上的LED紅外燈大多數用的是小功率燈管，芯片多為12MIL或許14MIL[1密耳(mil)=0.0254毫米(mm)],每只燈管正常的作業電壓是1.5V左右。用一數字萬用表，量程開關打至2V檔，丈量每一個燈管的作業電壓，假如正芯管，每一個燈管的作業電壓的誤差值在0.03V以內，若大于這個數值，特別是遍及較大時就闡明這批燈管絕非正芯。這種辦法對940納米的紅外燈相同適用。
It is still the core selection of wick core powder determines the quality of infrared light, between the two prices are very high, and is more than five times, an important reason for this is the quotation lamp various grades and ranks. The camera is most sensitive to the 850 - nm light spectrum, known as the red burst infrared tube, and the band's infrared lamp is also the most expensive. The lamp lamp plate removed, then find a adjustable regulated power supply. In a dark environment, the additional operating voltage, the output voltage to the lamp power supply connection of infrared light, infrared light at normal operation, and then gradually reduce the voltage to the lamp extinguished, see light degree lamp is not so common, if in the process of the lamp board all the lamp light is same, light work. Is the core; if some lights brighter lights had a slightly dark, so the wick people doubt the quality of. There is another way - measuring method. In the case of the normal operation of infrared measuring each lamp operating voltage. Now in the market most of LED infrared light using a small power tube, multi chip 12MIL or 14MIL[1 mil (MIL) =0.0254 mm (mm)], each lamp working voltage is about 1.5V. With a digital multimeter, range switch to 2V files, each a lamp operating voltage, if the voltage operation error of core tube, each lamp value within 0.03V, if more than this value, especially in larger when this group is the core tube is not clarified. This approach to 940 nm infrared light for the same.
　正芯燈管的優點是作業穩定，新時相同新，老時相同老，作業上三五年今后再看燈板上的燈，他們發光也十分共同。假如是嫌照度低，恰當調整作業電流即可使其康復青春。散芯燈管就不相同了，作業半年今后燈板上有的燈亮有的燈暗，一年以內不出毛病即是萬幸了。即便是換掉壞管子，不長時刻后依然出毛病，因為全體質量太差了。
The advantage of the positive tube is that the operation is stable, the new time is the same, the new is old, the old is the same old, and the 35 years of operation, we will look at the lights on the lamp board again, and they shine very much together. If it is suspected of low illumination, proper adjustment of the operating current can restore the youth. Powder core tube is not the same, the first half of next working lamp board some lights on some lights, within a year out of trouble is lucky. Even if the bad pipe is replaced, it will still go wrong after a long time, because the quality of the whole is too bad.
怎么辨別紅外燈的質量好壞竅門二、燈芯芯片巨細的區別
How to distinguish the difference between infrared light quality tips two, the wick of chip size
正規的辦法是用化學溶劑將膠體溶解后丈量燈芯的巨細。可是對于絕大多數人來說，即使你能夠溶解膠體也無法丈量出精確數據，因為咱們沒有那么精確的丈量工具[1密耳(mil)=0.0254毫米(mm)]。通常是看作業電流。通常來說12MIL的燈管最大作業電流不超越60毫安，14MIL的不超越70毫安。可是如今因為商場等等要素，有些一體機的12MIL的燈作業電流做到了80毫安。這個辦法又不判定了。可是能夠供給咱們一個參閱，即是作業電流大的芯片也許就大，可是電流大了壽數就短了。比方12MIL的燈作業電流做到了80毫安，那么它的壽數最多也即是2年。你知道這個，手頭上多備些燈板就能夠了，橫豎換一次燈板掙一次錢，出售及工程都有賺，咱們皆大歡喜。
Regular method is to use chemical solvent to dissolve the colloid after measuring wick size. But for most people, even if you're able to dissolve the colloid, you can't measure exact data, because we don't have the exact measuring tools [1 mil (MIL) =0.0254 mm [mm]]. Usually it depends on the operating current. In general, the maximum operating current of the 12MIL lamp is no more than 60 Ma, and the 14MIL is no more than 70 ma. But now because of shopping malls and other factors, some of the machine's 12MIL lights work current done 80 ma. This method is not decided. But we can supply a reference, which is perhaps the current chip operation is large, but the current life is short. For example, the 12MIL lamp operating current to 80 Ma, it is at most 2 years of life. You know this, do much to prepare some light board can, anyway for a lamp board to earn a money, sell and engineering have made us to the satisfaction of all.
怎么辨別紅外燈的質量好壞竅門三.看技術
How to identify the quality of the infrared light three. See technical tips
看技術就像看一個人相同，假如一個人穿戴邋里邋遢，很難信息他的作業會認真(當然陳景潤先生那樣的在外)。技術的好壞必定程度上闡明商品的質量，特別是焊接技術。燈管焊接時刻請求小于1.5秒，焊接時刻過長會直接影響到燈管的壽數。這一點咱們在實驗過程中已得到確定。
Look like a person, if a person is wearing a messy, hard information (of course his homework seriously like Mr. Chen Jingrun in). The quality of the technology, to some extent, illustrates the quality of the goods, especially the welding technology. Tube welding time request is less than 1.5 seconds, the welding time is too long will directly affect the lamp life. We have determined this point in the course of the experiment.
怎么辨別紅外燈的質量好壞竅門四、別的方面
How to identify the quality of the infrared lamp tips four, other aspects
從作業電壓看紅外燈的穩定性。仔細觀察燈板咱們不難發現燈板上若干個燈管串聯為一組，然后這若干組再并聯，然后構成全部燈板線路。每組燈管中假如有一個燈管出現問題，那么這一組燈就會不亮。如今商場上大多數燈板的作業電壓是12V，有些是24V。12V的燈多為6至7只燈管串聯為一組，24V的則為14只或許15只為一組串聯。相同是一只燈管有毛病，電壓高的不作業的燈管數量遠大于電壓低的燈。即是說作業電壓低的燈穩定性要高一些。
See from the infrared lamp operating voltage stability. Careful observation of the light plate, we can not find that the lights on a number of lamps in series into a group, and then these groups are connected in parallel, and then constitute all the lights board circuit. If there is a problem with a tube in each tube, the group of lights will not turn on. Nowadays, the voltage of most light boards in shopping malls is 12V, and some are 24V. 12V lights are mostly from 6 to 7 lamps in series, while 24V is 14, or 15 are in series. The same is a lamp, there is a problem, the high voltage, no work of the tube is much larger than the low voltage lamp. That is to say, low voltage operation, the lamp stability is higher.
　紅外線燈的質量主要取決于兩個方面，除了LED紅外二極管外即是供電電源了。紅外線燈絕大多數裝置在高處，一旦出現問題工程商首要拾麻煩，然后工程商再找出售商，出售商再找廠家;正本出售商的贏利就低，再來回地接貨發貨，到最后這一個燈不必定掙錢還有也許賠錢。所以電源的質量至關重要!
The quality of infrared light mainly depends on two aspects. Besides the LED infrared diode, it is the power supply. Most of the infrared lamp device in the high, once the problem of Engineering first pick up trouble, then the project and then find out the sale of business, sell business to find manufacturers; original vendor profit is low, come back to the last cargo delivery, this one will not light and perhaps lose money to make money. So the quality of the power supply is critical!
怎么辨別紅外燈的質量好壞竅門五、對于陣列式紅外燈
How to identify the quality of the infrared lamp five tips for IR array
陣列式紅外燈本來即是將若干個紅外LED芯片集中在一片基板上，其內部線路與通常的LED紅外燈相同。選購陣列式紅外燈必定注意其散熱辦法。好質量的陣列式紅外燈的后背都有一個厚厚的散熱片，并且陣列式基板與散熱片之間還涂有導熱硅脂，以便于散熱。
IR array is originally a plurality of infrared LED chip on a substrate, the internal wiring of the same with the usual LED lamp. The purchase must pay attention to the thermal IR array method. IR array of good quality back and have a thick heat sink, and between the array substrate and the heat sink is coated with thermal grease to facilitate heat dissipation.
陣列式紅外燈有體積小重量輕等優點，但也有它的缺陷，因為其內部相同是采取先串聯后并聯線路，一旦有一個芯片損壞就會致使一組燈不作業，一起無法替換這個損壞的芯片。假如損壞的組數多了的話就只得替換全部基板了，保護成本相對較高。
IR array has the advantages of small volume and light weight, but also has its defects, the same is taken because of its internal series parallel line, once there is a chip damage will cause a group of lights do not work together to replace the damaged chip. If the damage of the group more, then have to replace all the substrate, the protection costs are relatively high.
怎么辨別紅外燈的質量好壞竅門六、對于大功率紅外燈
How to identify the quality of infrared light for high-power infrared light, six tips
大功率紅外燈(食人魚封裝)最重視的即是散熱，燈板用鋁基板，且經過螺絲與機殼銜接，經過外殼散熱。別的多內置風機，經過強行風冷添加燈板與外殼的熱交換。假如是用通常的線路板，能夠判定這個燈板的質量必定不高，并且壽數也必定不長。
High power infrared lamp (piranha package) is the most important heat, with aluminum plate lamp plate, and after connection screw and shell after shell heat sink. Many other built-in fans are forced to cool air to add heat exchange between the light plate and the shell. If the circuit board normally, can judge the quality of the lamp board is not high and will not be life long.
怎么辨別紅外燈的質量好壞竅門七、對于紅外燈的壽數
How to identify the quality of the infrared lamp seven, infrared light for life tips
廠家通常標稱紅外燈的壽數為25000小時。實踐壽數與燈的生產技術、線路規劃、電源質量及作業環境等等都有聯系。
The factory usually lamp life 25000 hours nominal. The practice of life and light production technology, route planning, power quality and operation environment and so on are linked.
