Yini okufanele iqashelwe lapho uthenga izibani ze-LED zamaphrojekthi obunjiniyela?
Kungani "imininingwane" inquma impumelelo noma ukwehluleka kwephrojekthi yobunjiniyela lapho uthenga izibani ze-LED? 1.1 Umehluko oyinhloko phakathi kokuthengwa kobunjiniyela nokuthengwa komuntu ngamunye: usayizi omkhulu webhetshi, ithonya elibanzi, kanye nokubekezelelana kwamaphutha amancane ●Amaphutha okuthengwa komuntu siqu ...Funda kabanzi -
Umehluko phakathi kwezibani ze-LED ezingangeni manzi ze-IP65 ne-IP67: Izixazululo ezahlukene zokuzivumelanisa nezimo zangaphandle
Kungani izinga lokungangeni manzi “liyindlela yokuphila” yemigqa yokukhanya ye-LED yangaphandle? 1.1 Izinsongo eziyinhloko ezindaweni zangaphandle: Umthelela wemvula, uthuli kanye nomswakama emigqeni yokukhanya: ●Amacala okujikeleza okufushane kanye nokusha okubangelwa ukucwiliswa emanzini emvula noma ukuchaphaza ●Ukuqongelela kothuli kuthinta ukusha...Funda kabanzi -
Yiziphi izinzuzo ze-ics eyakhelwe ngaphakathi kanye ne-ics yangaphandle emigqeni yokukhanya ye-LED ngokulandelana?
Emkhakheni wezibani ze-LED, umehluko oyinhloko phakathi kwe-“IC eyakhelwe ngaphakathi” kanye ne-“IC yangaphandle” usesikhundleni sokufakwa kwe-chip yokulawula (i-IC), enquma ngqo imodi yokulawula, izici zokusebenza, ubunzima bokufaka kanye nesimo esisebenzayo...Funda kabanzi -
Iyini intambo yokukhanya engeyona eye-polar?
Imichilo yokukhanya ye-LED engeyona i-polar iwumkhiqizo olula futhi oguquguqukayo emkhakheni wokukhanya kwe-LED. Inzuzo yabo eyinhloko itholakala ekudluleni emkhawulweni we-polarity wezintambo zemichilo yokukhanya ye-LED yendabuko, okuletha ukulula okukhulu ekufakweni nasekusetshenzisweni. Okulandelayo...Funda kabanzi -
Ungakugwema kanjani omiyane ngokukhanya?
Omiyane sebebe ngabahamba phambili ekusakazeni amagciwane. Kufanele senze kanjani umsebenzi omuhle ekuvikeleni? Ingxenye 1: Isimiso sokuvimbela omiyane 1）Lapho ososayensi bezinambuzane befunda izici zomzimba womiyane, bathole ukuthi omiyane bazwela kakhulu futhi bathanda...Funda kabanzi -
Uyini umehluko phakathi kwemigqa yokukhanya ye-AC voltage kanye nemigqa yokukhanya ye-DC voltage?
Izici zokunikezwa kwamandla, ukwakheka, ukusetshenziswa, kanye nokusebenza kwemigqa yokukhanya ye-AC (alternating current) kanye ne-DC (direct current) ziphakathi komehluko omkhulu phakathi kwazo. Umehluko oyinhloko ungokulandelayo: 1. Imigqomo yokukhanya ye-AC njengomthombo wamandla Le migqa i...Funda kabanzi -
Yiziphi izici ezihlobene nenani eliphikisana nokukhanya kwemicu yokukhanya?
Izinto eziningana zingathinta indlela ukukhanya okubonwa ngayo nokuthi ukukhanya okukhanyayo akumnandi kangakanani kubabukeli, okubuye kuthinte inani elimelene nokukhanya kwemigqa yokukhanya. Okulandelayo yizinto eziyinhloko ezithinta ikhono lemigqa yokukhanya lokunciphisa ukukhanya: 1. Ukukhanya: Into eyodwa ebalulekile okufanele uyicabangele...Funda kabanzi -
Iyini idizayini ngaphandle kwesibani esikhulu?
Ngokuvamile okwaziwa ngokuthi “ukukhanya okunezendlalelo” noma “ukukhanya okuzungezile,” ukuklama indawo engenalo ukukhanya okuyinhloko kuhilela ukusebenzisa imithombo ehlukahlukene yokukhanya ukukhiqiza umoya okhanyayo kahle ngaphandle kokuthembela ku-headset eyodwa. Okulandelayo ezinye zezingxenye ezibalulekile kanye...Funda kabanzi -
Uyini umehluko phakathi kwezibani ze-strip kanye nezibani ze-LED?
“Izibani ze-strip” kanye “nezibani ze-LED” azifani; zibhekisela ezicini ezihlukile zobuchwepheshe bokukhanyisa. Ngezansi kukhona ukufingqwa komehluko: Incazelo Yezibani ze-LED Izibani ze-LED (Light Emitting Diode) ziwuhlobo lobuchwepheshe bokukhanyisa obukhiqiza ukukhanya kusetshenziswa i-semic...Funda kabanzi -
