產(chǎn)品描述

車(chē)規級二極管簡(jiǎn)稱(chēng)為LED是指由含鎵(Ga)、砷(As)、磷(P)、氮(N)等的化合物制成的可以把電能轉化為光能的半導體二極管的一種。

當電子與空穴復合時(shí)能輻射出可見(jiàn)光，因而可以用來(lái)制成車(chē)規級二極管。在電路及儀器中作為指示燈，或者組成文字或數字顯示。砷化鎵二極管發(fā)紅光，磷化鎵二極管發(fā)綠光，碳化硅二極管發(fā)黃光，氮化鎵二極管發(fā)藍光。因化學(xué)性質(zhì)又分有機車(chē)規級二極管OLED和無(wú)機車(chē)規級二極管LED。下面來(lái)了解一下車(chē)規級二極管的正負極怎么區分。

用萬(wàn)用表R×1K擋，紅、黑兩表筆交替接車(chē)規級二極管的兩根引線(xiàn)，當發(fā)現其中一次測量，表針先向右擺動(dòng)一定距離，然后表針在此位置上開(kāi)始輕微抖動(dòng)(振蕩)，擺動(dòng)幅度在一小格左右。這種現象說(shuō)明車(chē)規級二極管內部的集成電路在萬(wàn)用表內部1.5V電池電壓的作用下開(kāi)始振蕩，輸出的脈沖電流使指針產(chǎn)生抖動(dòng)，只是因為電壓太低還不能使車(chē)規級二極管發(fā)光。但此現象說(shuō)明萬(wàn)用表紅、黑表筆的接法是正確的，即萬(wàn)用表黑表筆接的是車(chē)規級二極管的正極。

注意：在判斷車(chē)規級二極管正、負極時(shí)，千萬(wàn)不要像測普通二極管那樣，認為電阻小的那次測量，黑表筆接的是二極管正極。
