一,LED的封装技能,这就需求我们找到一个牢靠的出产厂商.
First, LED Packaging skills, which requires us to find a reliable manufacturer
二,电源的规划, 由于LED的离散性特强，压降、波长、光色、高度不同很大，只要上述几个指标共同的LED才干并联在一起运用,反之, 压下降的电流很大，压降高的电流很小，形成光色、高度不均，电流大的寿数缩短。
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的作业电源, 按电子职业“规则”，实际出产应用时只能用到极限值的60%，才干确保正常的功能和寿数。如今许多广告厂家在作LED发光字的时分,为了寻求亮度硬性拨高LED的电流,这无异于一种竭泽而渔饮鸠止渴.所以在寻求最大亮度的一起,确保安全电流.
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, 关于防止静电. LED底座最佳是运用抗静电的PVC插槽.
Four, to prevent static electricity. LED base is the best use of anti-static PVC slot
五,LED电源.如今许多店为了节约变压器,通常选用二百二十伏加电阻串接LED的作法,榜首,无稳压,无恒流,第二,LED的PN结通正弦波阻负弦波,所以,沟通二百二中有一百一十伏负半波被无形的浪费了,还有,一灯一个电阻,电阻所浪费了一部分的电量.这么作,捐害了LED的运用寿数也增加了用电量. 其次是铁芯变压器，降压整流成直流。粗笨、不稳压，但可靠性好. 还有即是如今很多运用的开关电源，效率高，价格适中，但质量容易掺假，有时会焚毁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.
