杯/平頭:此種支架一般做對角度、亮度要求不是很高的材料，比其他支架要短10mm左右。Pin 間距為2. 28mm;B、2003杯/平頭:一般用來做φ 5以上的Lamp ，湖南投光燈led, 外露pin長為+29mm、-27mm，Pin 間距為2.54mm;C、2004杯/平頭:用來做用來做φ 3左右的Lamp， Pin長及間距同2003支架;D、2006:兩極均為平頭型，用來做閃爍、兩極均為平頭型，用來做閃爍Lamp，固IC，湖南投光燈led，焊多條線;F、2009:用來做雙色的Lamp,杯內(nèi)可固兩顆，三支pin腳控制極性;G、2009-8/3009:用來做三色的Lamp，杯內(nèi)可固三顆晶片，四支pin腳，湖南投光燈led。首先我們可以先檢查一下，led燈珠是否因供電電源部分的原因而沒有正常工作導(dǎo)致燈珠不亮。湖南投光燈led</p><div

驅(qū)動方式現(xiàn)在通行的有兩種:其一是一個恒壓源供多個恒流源，每個恒流源單獨給每路LED供電。這種方式，組合靈活，一路LED故障，不影響其他LED的工作，但成本會略高-一點。另一種是直接恒流供電，LED串聯(lián)或并聯(lián)運行。它的優(yōu)點是成本低一點，但靈活性差，還要解決某個LED故障，不影響其他LED運行的問題。這兩種形式，在-段時間內(nèi)并存。<span
