Kungani izibani ze-LED ziba mnyama futhi zibe mnyama?
Kuyinto evamile kakhulu ukuthi izibani eziholayo ziba mnyama futhi zibe mnyama njengoba zisetshenziswa. Fingqa izizathu ezingenza kube mnyama ukukhanya kwe-LED, okungeyona into engaphezu kwamaphuzu amathathu alandelayo. 1.Shayela ubuhlalu bezibani ze-LED ezilimele kudingeka ukuthi usebenze ku-DC voltage ephansi (ngaphansi kuka-20V), kodwa ama...Funda kabanzi -
Ayini ama-LED "COB" futhi Kungani Abalulekile?
Ayini ama-LED e-Chip-on-Board (“COB”)? I-Chip-on-Board noma i-“COB” ibhekisela ekufakweni kwe-chip ye-LED engenalutho lapho kuxhunywana ngokuqondile ne-substrate (njenge-silicon carbide noma isafire) ukuze kukhiqizwe ama-LED afanayo. Ama-COB LED anenani lezinzuzo ngaphezu kobuchwepheshe be-LED obudala, obufana ne-Surface Mount...Funda kabanzi -
Imikhiqizo yokukhanyisa izohlakanipha kakhulu futhi incike kakhulu
Eminyakeni yamuva, imakethe ye-LED yomhlaba wonke ibilokhu ikhula ngokushesha, eye yashintsha kancane kancane izibani ze-incandescent, izibani ze-fluorescent neminye imithombo yokukhanyisa, futhi izinga lokungena liye laqhubeka landa ngokushesha. Kusukela ekuqaleni kwalo nyaka, kusobala ukuthi imakethe yabahlakaniphile...Funda kabanzi -
Funda Mayelana Nokukhanya Kwe-LED
Okuyisisekelo Kokukhanya Kwe-LED Ayini ama-LED futhi asebenza kanjani? I-LED imele i-light emitting diode. Imikhiqizo yokukhanyisa kwe-LED ikhiqiza ukukhanya kufika ku-90% ngendlela ephumelelayo kunama-incandescent amalambu. Zisebenza kanjani? Umsinga kagesi udlula ku-microchip, ekhanyisa ukukhanya okuncane ukuze...Funda kabanzi -
Ukubuka konke kwe-LED emhlophe
Ngokuthuthuka nokuthuthuka komphakathi, izindaba zamandla kanye nezemvelo ziye zanda kakhulu emhlabeni. Ukongiwa kwamandla kanye nokuvikelwa kwemvelo sekuya ngokuya kuba umfutho oyinhloko wenqubekelaphambili yomphakathi. Ezimpilweni zabantu zansuku zonke, isidingo sokukhanyisa...Funda kabanzi -
Iyini i-LED yamandla okushayela njalo amandla okunikezwa kwamandla?
Esinye sezihloko ezishisa izikhotha embonini yakamuva yokuphakelwa kukagesi we-LED i-led ehlala njalo yamandla. Kungani ama-LED kufanele ashayelwe amandla angaguquki? Kungani ungakwazi ukushayela njalo amandla? Ngaphambi kokuxoxa ngalesi sihloko, kufanele siqale siqonde ukuthi kungani ama-LED kufanele ashayelwe amandla angaguquki?
