Izindawo ezishisayo eziyishumi zokuthuthukiswa kobuchwepheshe bohlelo lokusebenza lwe-LED
Okokuqala, ukusebenza kahle kwamandla okuphelele kwemithombo yokukhanya ye-LED nezibani.Ingqikithi yamandla okusebenza kahle = ukusebenza kahle kwe-quantum yangaphakathi × Ukusebenza kahle kokukhishwa kokukhanya kwe-Chip × Ukusebenza kahle kokukhishwa kokukhanya kwephakheji × Ukuphumelela okujabulisayo kwe-phosphor × Ukusebenza kahle kwamandla × Ukusebenza kahle kwesibani.Okwamanje, leli nani lingaphansi kwe-th...Funda kabanzi -
Izinkomba eziyisithupha zokwahlulela ukusebenza komthombo wokukhanya we-LED nobudlelwano bawo
Ukwahlulela ukuthi ingabe umthombo wokukhanya we-LED uyilokho esikudingayo, ngokuvamile sisebenzisa i-sphere ehlanganisayo ukuze sihlole, bese sihlaziya ngokuya ngedatha yokuhlola.I-sphere evamile yokuhlanganisa inganikeza amapharamitha ayisithupha abalulekile alandelayo: ukuguquguquka okukhanyayo, ukusebenza kahle okukhanyayo, i-voltage, ukuxhumanisa umbala, umbala...Funda kabanzi -
Kuyini isibani se-LED esingcwatshwe
Umzimba wesibani ongcwatshwe we-LED wenziwe nge-adze noma insimbi engagqwali nezinye izinto, ezihlala isikhathi eside, ezingangeni manzi futhi zihle kakhulu ekulahlekeni kokushisa.Ngokuvamile singathola ubukhona bayo kumaphrojekthi wokukhanyisa we-landscape wangaphandle.Ngakho-ke yini eholwa isibani esingcwatshwe futhi yiziphi izici zalolu hlobo lwesibani...Funda kabanzi -
Amakhono okukhetha nokuhlukaniswa kwemithombo yokukhanya yombono womshini
Njengamanje, imithombo yokukhanya ebonakalayo efanelekile ihlanganisa isibani se-high-frequency fluorescent, isibani se-fiber optical halogen, isibani se-xenon nomthombo wokukhanya we-LED.Izinhlelo zokusebenza eziningi ziyimithombo yokukhanya eholayo.Nansi imithombo yokukhanya ye-LED eminingana evamile ngokuningiliziwe.1.
