一,LED的封裝技能,這就需求我們找到一個牢靠的出產廠商.
First, LED Packaging skills, which requires us to find a reliable manufacturer
二,電源的規劃, 由于LED的離散性特強，壓降、波長、光色、高度不同很大，只要上述幾個指標共同的LED才干并聯在一起運用,反之, 壓下降的電流很大，壓降高的電流很小，形成光色、高度不均，電流大的壽數縮短。
Two, the power of planning, because of discrete LED characteristics, pressure drop, wavelength, color, height, as long as the LED to the several common parallel index together with, on the other hand, the current pressure decreased greatly, the current high pressure drop is very small, the formation of color, highly uneven, large current life shortening.
三, LED的作業電源, 按電子職業“規則”，實際出產應用時只能用到極限值的60%，才干確保正常的功能和壽數。如今許多廣告廠家在作LED發光字的時分,為了尋求亮度硬性撥高LED的電流,這無異于一種竭澤而漁飲鳩止渴.所以在尋求最大亮度的一起,確保安全電流.
Three, the operation of power supply LED, according to the electronic occupation "rules", the actual application can only be used when the limit value of 60%, to ensure the normal function and life. Now many manufacturers in time for advertising LED luminous characters, in order to find the current LED high brightness rigid dial, which is tantamount to an outright Jiezeeryu. So looking for a maximum brightness, to ensure the safety of current.
四, 關于防止靜電. LED底座最佳是運用抗靜電的PVC插槽.
Four, to prevent static electricity. LED base is the best use of anti-static PVC slot
五,LED電源.如今許多店為了節約變壓器,通常選用二百二十伏加電阻串接LED的作法,榜首,無穩壓,無恒流,第二,LED的PN結通正弦波阻負弦波,所以,溝通二百二中有一百一十伏負半波被無形的浪費了,還有,一燈一個電阻,電阻所浪費了一部分的電量.這么作,捐害了LED的運用壽數也增加了用電量. 其次是鐵芯變壓器，降壓整流成直流。粗笨、不穩壓，但可靠性好. 還有即是如今很多運用的開關電源，效率高，價格適中，但質量容易摻假，有時會焚毀LED。
Five, LED power supply. Now many stores in order to save the transformer, usually with two hundred and twenty plus resistor are connected in series, LED approach, the list, no regulator, no constant current, second LED sine wave sine wave through the PN junction resistance negative, so there are one hundred and ten volts negative half wave is invisible waste, and communication two hundred and twenty,. A resistance, resistance of the wasted part of electricity. So, detrimental to LED using his increased use of electricity. The iron core transformer, DC step-down rectifier. Clumsy, unregulated, but good reliability. There is now a lot of use of switching power supply, high efficiency, moderate price, but the quality is easy to adulterate, sometimes burning LED.
