Kunezinkomba eziningi zepharamitha zeI-LED ubuhlalu. Uma kuqhathaniswa nabachwepheshe abaningi be-elekthronikhi, ukuze baqonde imakethe ye-LED, kuyadingeka ukuqonda ulwazi oluthile oluyisisekelo lwama-LED ubuhlalu, kufaka phakathi amanye amapharamitha aholwa kanye nezinkomba zokusebenza.
I-01 ihole ubuhlalu yamanje
Okokuqala, okukhona kwamanje kobuhlalu be-LED, okuvame ukubhekisa umkhawulo odlulile kwamanje kobuhlalu be-LED, kusho umkhawulo wamanje (uma) ubuhlalu obukholwayo lapho isigxobo esihle sixhumeke esigxotsheni esihle seukunikezwa kwamandla kagesiFuthi i-pole engemihle ixhumeke esigxotsheni esingesihle sokunikezwa kwamandla. Njengamanje, yiyona ezungeze i-20mA. I-attenuation ekhanyayo yamanje ye-General LED ubuhlalu ayikwazi ukwedlula i-IF2 / 3, cishe phakathi kwe-15MA ne-18MA. Ukuqina okukhanyayo kobuhlalu be-LED kuhlotshaniswa kahle uma kungaphakathi kwebanga elihambisanayo. Lapho uma> 20m, ukuthuthukiswa kokukhanya akujwayelekile. Ngakho-ke, ngokuvamile kunengqondo ukukhetha okusebenzayo kwamanje kobuhlalu be-LED cishe ngo-17-19MA. Ngokuthuthuka okuqhubekayo kobuchwepheshe, ubuhlalu obunamandla aphezulu buyavela njalo, njenge-0.5WWNED (uma = 150m), 1wled (uma = 350mma), kanye nokucaciswa okwengeziwe kwe-bead.
I-02 yahola impilo yesikhathi sokuphila
I-Lifespan of Led Beads nayo iyinkomba ebalulekile. Encwadini yokufundisa yama-LED ubuhlalu, kuvezwa ukuthi zingasetshenziswa isikhathi esingakanani, njengokusebenza kwamahora angaba ngu-50000. Kodwa-ke, kufanele kuqashelwe ukuthi isikhathi sokuphila sobuhlalu be-LED asikwazi ukumane sinqunywe ngokuthi ngabe basasebenza yini. Yingoba i-LED ayinayo inkinga yokuncibilika kuncibilika njengamalambu wendabuko, ngakho-ke ngeke kuyeke ukusebenza ngqo, kepha kuzokwehla kancane kancane ngokuhamba kwesikhathi. Ubuhlalu obusezingeni eliphakeme be-LED bungalondolozela cishe ama-60% okukhanya kwabo kokuqala ngemuva kwamahora angama-50000 okuqhubeka. Indlela engcono kakhulu yokunweba isikhathi sokuphila kobuhlalu se-LED ukunciphisa amandla afudumele akhiqizwe ngama-chip aholwa, okuyimbangela eyisisekelo yokulahleka kwe-LED.
Ngakho-ke, kuphela ngokuthola ukuqonda okungcono kwe-LED Bead Parameter Izinkomba esingazikhetha kangcono imikhiqizo yeBead Bead nemikhiqizo ye-LED Bead.
