Okwamanje, abaningiImikhiqizo ye-LEDsebenzisa imodi yokushayela yamanje ukuze ushayeleI-LED. Imodi yokuxhumeka kwe-LED iphinde idizayine izindlela ezahlukene zokuxhuma ngokuya ngezidingo zangempela zesekethe. Ngokuvamile, kunezinhlobo ezine: uchungechunge, ukuhambisana, okuxubile kanye nohlu.

1. Imodi yochungechunge

Isifunda salolu chungechunge lokuxhumanisa silula. Ikhanda nomsila kuxhunywe ndawonye. I-current egeleza nge-LED ngesikhathi sokusebenza inhle kakhulu. Ngenxa yokuthi i-LED iyidivayisi yohlobo lwamanje, ingaqinisekisa ngokuyisisekelo ukuthi ukushuba okukhanyayo kwe-LED ngayinye kuyahambisana. Imodi yokuxhumeka kwe-LED inezinzuzo zokujikeleza okulula nokuxhumeka okulula. Kodwa kukhona futhi kusimo esibulalayo, okungukuthi, lapho omunyeAma-LEDinephutha lesifunda elivulekile, lizokwenza ukuthi yonke intambo yesibani se-LED iphume futhi ithinte ukuthembeka kokusetshenziswa. Ngakho-ke, kuyadingeka ukuqinisekisa ikhwalithi enhle kakhulu ye-LED ngayinye, ukuze ukwethembeka kuzothuthukiswa ngokufanele.

Kuyaqapheleka ukuthi uma i-LED isetshenziswa amandla kagesi okushayela njalo amandla okushayela i-LED, amandla wesekethe azokhula lapho i-LED ifinyezwa. Uma inani elithile lifinyelelwa, i-LED izolimala, okuholela ekulimaleni kwawo wonke ama-LED alandelayo. Kodwa-ke, uma amandla okushayela amanje e-LED asetshenziswa njalo ukushayela i-LED, yamanje ngokuyisisekelo izohlala ingashintshile lapho i-LED ifinyezwa, engenawo umthelela kuma-LED alandelayo. Kungakhathaliseki ukuthi iyiphi indlela yokushayela, uma i-LED isiyisifunda esivulekile, isifunda sonke ngeke sikhanyiswe.

2. Imodi ehambisanayo

Imodi ehambisanayo ibonakala ngokuxhuma okufanayo kwekhanda nomsila we-LED, futhi i-voltage ethwalwa yi-LED ngayinye iyalingana ngesikhathi sokusebenza. Kodwa-ke, okwamanje akulingani ngempela, ngisho nama-LED wemodeli efanayo, ukucaciswa kanye nenqwaba. Lokhu kungenxa yenqubo yokukhiqiza nezinye izizathu. Ngakho-ke, ukusatshalaliswa kwamanje okungalingani kwe-LED ngayinye kungase kunciphise impilo yesevisi ye-LED ngamandla amanje kakhulu uma kuqhathaniswa namanye ama-LED, futhi kulula ukuvutha ngokuhamba kwesikhathi. Isifunda sale modi yokuxhumana ehambisanayo silula, kodwa ukwethembeka akuphakeme. Ikakhulukazi uma kunenombolo enkulu yama-LED, amathuba okuhluleka aphezulu.

Kuyaphawuleka ukuthi i-voltage edingekayo ekuxhumekeni okufanayo iphansi, kodwa ngenxa yokwehla kwe-voltage eya phambili ehlukene ye-LED ngayinye, ukukhanya kwe-LED ngayinye kuhlukile. Ukwengeza, uma i-LED eyodwa ifinyezwa, isifunda sonke sizofinyezwa, futhi amanye ama-LED awakwazi ukusebenza ngokujwayelekile. Ngomjikelezo ovulekile oholayo, uma kusetshenziswa idrayivu yamanje eqhubekayo, okwamanje okwabelwa ama-LED asele kuzokwanda, okungaholela ekulimaleni kwama-LED asele, Nokho, ukusetshenziswa kwe-voltage drive engaguquki ngeke kuthinte ukusebenza okuvamile kwe-LED. yonke isifunda se-LED.

3. Imodi yeHybrid

Ukuxhumana kweHybrid kuyinhlanganisela yochungechunge nokuhambisana. Okokuqala, ama-LED amaningana axhunywe ochungechungeni, abese exhunywa ngokufana kuzo zombili iziphetho zokunikezwa kwamandla okushayela kwe-LED. Uma ama-LED engaguquguquki ngokuyisisekelo, le ndlela yokuxhuma iyamukelwa ukuze i-voltage yawo wonke amagatsha ilingane ngokuyisisekelo futhi egelezayo egatsheni ngalinye ihambisane ngokuyisisekelo.

Kuyaphawuleka ukuthi imodi yokuxhumeka kwe-hybrid isetshenziswa ikakhulukazi endabeni yenombolo enkulu yama-LED, ngoba le modi iqinisekisa ukuthi ukwehluleka kwe-LED egatsheni ngalinye kuthinta kuphela ukukhanya okuvamile kwaleli gatsha kakhulu, okuthuthukisa ukuthembeka uma kuqhathaniswa uchungechunge olulula kanye nemodi yokuxhumana ehambisanayo. Njengamanje, le ndlela isetshenziswa kabanzi kumalambu amaningi e-LED aphezulu ukuze kuzuzwe imiphumela ewusizo kakhulu.

4. Imodi ye-Array

Ifomu eliyinhloko lemodi yohlelo yileli: igatsha lithatha ama-LED amathathu njengeqembu futhi lixhunywe kumatheminali okukhiphayo e-UA, Ub kanye ne-UC okukhipha umshayeli ngokulandelanayo. Uma ama-LED amathathu egatsheni ejwayelekile, ama-LED amathathu azokhanya ngesikhathi esisodwa; Uma i-LED eyodwa noma amabili ehluleka futhi evulekile isekethe, ukusebenza okuvamile okungenani kwe-LED eyodwa kungaqinisekiswa. Ngale ndlela, ukwethembeka kweqembu ngalinye lama-LED kungathuthukiswa kakhulu, futhi ukwethembeka okuphelele kwayo yonke i-LED kungathuthukiswa. Ngale ndlela, amaqembu amaningi okufaka amandla okufakwayo ayadingeka ukuze kuthuthukiswe ukwethembeka komsebenzi we-LED futhi kuncishiswe izinga lokuhluleka kwesekethe lilonke.
