　1、芯片輻射功率等級的差異：
1, chip radiation power level difference:
以廈門三安的芯片為例，S-23BBMUP-C*******，芯片尺度為23X10mil，這個芯有4個輻射功率等級(@20mA)，輻射功率越高，做出的燈珠越亮。
In the case of Xiamen Sanan chip, S-23BBMUP-C*******, chip scale 23X10mil, the core 4 radiation power level (@20mA), the radiation power is high, make the lamp more bright.
D24 輻射功率 26-28mW
D24 radiation power 26-28mW
D25 輻射功率 28-30mW
D25 radiation power 28-30mW
D26 輻射功率 30-33mW
D26 radiation power 30-33mW
D27 輻射功率 33-36mW
D27 radiation power 33-36mW
D24與D27的輻射功率相差8mW，也即是說，一樣尺度的芯片，做出的燈珠亮度不一樣，相差許多，需求了解芯片的輻射功率等級。
The microwave power is D24 and D27 is 8mW, that is to say, the same scale of the chip, make the lamp brightness is not the same, are many, needs to understand the radiation power level chip.
2、燈珠支架資料的差異：
The difference between the 2, the lamp bracket materials:
目前商場上有鋁支架、黃銅支架、紫銅支架等，鋁支架最廉價，紫銅支架最貴，報價相差十幾倍。即便是紫銅支架，鍍銀的報價也有凹凸之分，商場通常稱為好支架的，大部分是黃銅鍍銀做的。
At present, there are aluminum bracket, brass bracket, copper bracket, etc. the aluminum bracket is the cheapest and the copper bracket is the most expensive. The quotation is ten times more than the difference. Even if the copper stent, silver plated quote also has a concave and convex points, shopping malls are usually called good stent, most of the brass silver plating.
3、芯片尺度的差異：
3 chip scale differences:
通常所報的芯片尺度是以mil，如果沒有高倍丈量顯微鏡，通常是很難差異的，芯片越大越亮，咱們能夠經過核算芯片面積來對比芯片巨細，如23X10，芯片的面積是230平方mil，用芯片面積差異芯片巨細才是個好辦法。
Usually reported by the chip scale is mil, if there is no high power microscope measurement, it is usually difficult difference, the bigger the chip light, we can through the accounting chip area compared to chip size, such as 23X10, the chip area is 230 square mil, with the area of the chip chip size difference is a good way to.
4、焊線資料的差異：
4 、 difference of welding line data:
芯片與支架是用金線焊接辦法完結電極連通，目前商場上有合金線、純金線兩種，純金線最佳，金線依照粗細又分0.7、0.9、1.0、1.2等，金線越粗，熱組越低，壽數越長，所有要問清金線的原料和直徑。
The chip and the bracket is connected to the end of the electrode with gold alloy wire, welding, there are currently two kinds of pure gold market, pure gold, gold in thickness is divided into 0.7, 0.9, 1, 1.2, gold is thicker, the heat group is low, life is long, all to ask the raw materials and the diameter of gold.
5、熒光粉的差異：
5. Difference of phosphor:
白光燈珠是用藍光芯片加**熒光粉做成的，熒光粉主要分鋁酸鹽和硅酸鹽，鋁酸鹽功能優于硅酸鹽，鋁酸鹽最為代表的是YAG，YAG功能安穩，光衰低，硅酸鹽本身的化學安穩性較差，但亮度比YAG高，想做功能安穩的產品，可不要被所謂的高亮度忽悠了，這但是個大問題。
The white light lamp is made of blue chip with * * fluorescent powder, fluorescent powder consists of aluminate and silicate, aluminate silicate aluminate is better than, the most representative is YAG, YAG function stable, low light decay, Portland itself chemical stability is poor, but the brightness is higher than YAG, want to do function stable products, can not is the so-called high brightness flicker, but this is a big problem.
6、膠水的差異：
6, glue difference:
熒光粉是要和膠水拌和后在點在芯片上的，膠水的好壞影響到光衰和色漂移，差的膠水時間長會黃化，光衰加大，好的膠水是果凍膠。
The fluorescent powder and glue to mixing at the point on the chip, affect the glue to decay and color drift, poor glue long time will increase the light yellow, jelly glue is good.
7、分色、分壓與分光的標準：
7 、 standards of color separation, pressure distribution and separation:
分色：即是色溫分檔，如3200K-3350K為一檔，規范的封裝廠會提供色溫的BIN碼，色溫分檔越小越好，色溫分檔小，做出的光源光的色彩一致性好。
Color separation: that is the color temperature of the file, such as 3200K-3350K for a file, the standard packaging factory will provide color temperature BIN code, color temperature, the smaller the better file, color temperature, small files, make the light source of light color consistency is good.
分壓：即是芯片的電壓分檔，如3.0V-3.15V，關于光源是串并聯的銜接方法，電壓分檔控制在0.15V以內，這么光源的電流分布均勻，有利于進步光源的壽數。
Pressure: is the chip voltage range, such as 3.0V-3.15V, a light source is the method of series parallel connection, the voltage grading control within 0.15V, so the uniform current distribution of light source, light source is conducive to the progress of life.
分光：即是燈珠亮度分檔，有流明分檔或許光強度分檔，關于用于照明光源，最佳選用流明分檔。建議收購LED，還是以光效為根據，高光效的產品，才會節能，壽數長。
Light: is the lamp brightness range, a lumen tranche or tranches of a light intensity, for lighting, the best selection of lumen tranches. The proposed acquisition of LED, or in the light effect on high efficiency products, will be energy saving, long life.
以上是收購LED燈珠的幾條準則，只要了解這些內容，并把這些條款做在你的定貨合同里，你才會有時機維護自個的權益，否則，吃虧的一定是你，燈珠的報價是最誘人的陷阱，一旦陷下去，公司只要關門走人了。
These are a few guidelines to buy LED beads, as long as the understanding of the content, and these terms in your orders, you will have the opportunity to maintain self interests, otherwise, you must suffer, beads offer is the most attractive trap, once the sink, as long as the company closed.
