Okwangoku, inqanaba lomgangatho kwizibane zesitrato ezi-LED kwintengiso ayilingani. Kwiindawo ezininzi, izibane zesitrato ezikhokelwayo azizukubonakala ziqaqambile kungekudala. Emva kophando lwezibane ezifudukayo ze-LED, unobangela weli phenyane kukuba ukukhanya kwesitrato esikhokelwa sisitrato esiphantsi. Xa ubushushu bokubekwa kwempahla nobushushu buhlwempuzekile, amaqondo obushushu angaphakathi okukhanya e-LED aya kuphakama kakhulu. Xa iqondo lobushushu le-LED liphuma, ukuchasana nokuchasa kwayo kuncipha, kukhokelela ekuncipheni kwevolthi yokujika.
Phantsi kweemeko ze-voltage efanayo, ubushushu bangaphakathi bunyuka ukukhanya kwe-LED kuya kwandisa i-LED yangoku. Ukunyuka kwezizathu ezibangela ukuba amaqondo obushushu aphakame ngakumbi, oko kubangela umjikelo ombi ukutshisa i-chip ye-LED. Ngapha koko, amaqondo obushushu angaphakathi okukhanya esitratweni i-LED kuphakame kakhulu, oko kubangela ukucocwa okukhanya kwe-CHIP ukuze kuqine kwaye kungabi nako ukuqaqamba okukhanyayo kungekudala. Ke siyintoni isizathu sokwenza ubushushu obungalunganga bokusebenza kokukhanya kwesitalato?
Okokuqala, umgangatho wesitrato esimahlazi.
I-chip ye-LED isetyenziselwe ukuqhutywa kweqondo lokuqhuba eliphantsi, kwaye iqondo lobushushu lokufa eli-LED alidlulisile kumphezulu (ubushushu wangaphakathi kunye nokubanda). Nokuba ubushushu bubushushu bongezwa, ubushushu bangaphakathi alunakuchithwa ngokupheleleyo, kwaye ke ukukhanya kwesitalato i-LED ayifudumezi ngaphakathi.
Okwesibini, iqondo lobushushu liphakame ngenxa yokunikezelwa kwamandla e-LED.
Umgangatho wamandla okukhupha isitalato ayilunganga. Xa i-LED ivuliwe, i-non-Noncilgod yombane kunye notshintsho olubuthathaka lwamandla luya kubangela okwangoku i-CHIP ye-LED yokunyusa, oluya kubangela ukuba iqondo lobushushu langaphakathi liphezulu kakhulu, eliza kuchaphazela ukulimaza kobushushu.
Wonke umntu kufuneka anikele ingqalelo kwi-ongetion yezibane zesitrato ezi-LED. Xa uthenga, zama ukukhetha izibane ezifudukayo ezikhokelwa zikhokelwa, kwaye unikele ingqalelo rhoqo, ukwenzela ukuqinisekisa uzinzo lwezibane zesitrato ze-LED.
