Inhlanganisela yama-LED abomvu, aluhlaza okwesibhakabhaka kumojula eyodwa ngokuya ngemodeli yombala we-RGB, ukukhanya okumhlophe kukhiqizwa ingxube efanele yokukhanya okubomvu, okuluhlaza okwesibhakabhaka. Indlela emhlophe ye-RGB ikhiqiza ukukhanya okumhlophe ngokuhlanganisa okukhiphayo okuvela kuma-LED abomvu, aluhlaza naluhlaza.
Ngiyibeka kanjani i-RGB yami iholele kokumhlophe?
Isibonelo, ukuze udale umbala ophuzi, isilawuli sihlanganisa izingxenye ezilinganayo zokubomvu nokuluhlaza (okuluhlaza okwesibhakabhaka kuvaliwe). Ukuze kukhiqizwe umbala omhlophe kusetshenziswa i-RGB 5050 LED, isilawuli sihlanganisa izingxenye ezilinganayo zokubomvu, okuluhlaza okotshani nokuluhlaza okwesibhakabhaka.
Uzenza kanjani izibani ze-LED zibe mhlophe?
Ekuhlanganiseni kombala okungeziwe, ukukhanya okubomvu, okuluhlaza okwesibhakabhaka nokuluhlaza kuhlanganisa ukwenza ukukhanya okumhlophe. Ngokuya ngomphumela we-spectral wama-LED, akuyona yonke imibala emithathu ehlala idingeka.
Ingabe i-RGB LED Strip ingaba mhlophe?
Nakuba i-RGB ingakhiqiza umbala osondele komhlophe, i-LED emhlophe ezinikele ihlinzeka ngethoni emhlophe ecwebe kakhulu futhi ikuvumela inketho ye-chip emhlophe efudumele noma epholile. I-chip emhlophe eyengeziwe futhi ihlinzeka ngendawo eyengeziwe yokuxuba imibala nama-chips e-RGB ukuze kwakhe uhla olukhulu lwamathunzi ahlukile.
Ingabe izibani ze-LED zingaba mhlophe?
Ama-LED awakhiqizi ngokuqondile ukukhanya okumhlophe. … Ukusebenzisa i-LED eluhlaza okwesibhakabhaka ene-phosphor coating ukuguqula ukukhanya okuluhlaza kube ukukhanya okumhlophe ngenqubo ebizwa nge-fluorescence. Kuhlanganisa ama-LED abomvu, aluhlaza okwesibhakabhaka naluhlaza ukukhiqiza ukukhanya okumhlophe. Ukukhanya okumhlophe kukhiqizwa ngokuhlukahluka kokuqina kwama-chips abomvu, aluhlaza okwesibhakabhaka naluhlaza.
Kungani ukukhanya kwe-LED kumhlophe?
Ama-LED aguqulwe nge-phosphor akhiqiza ukukhanya okumhlophe ngokuhlanganisa ukukhanya kwemibala ehlukahlukene. Kumklamo owodwa wezohwebo (kwesokunxele), ukukhanya okuvela ku-LED ekhipha okwesibhakabhaka kujabulisa i-phosphor ephuzi. Okuhlaza okwesibhakabhaka nokuphuzi kuhlangana ukwenza ukukhanya okumhlophe.
Kungani izibani ze-LED ezimhlophe ziluhlaza okwesibhakabhaka?
Ama-LED amaningi “amhlophe” asebenzisa umthombo oluhlaza okwesibhakabhaka we-monochromatic (hhayi i-UV), obese ufakwa nge-fluoresced ukuya kumaza aphansi nge-phosphor. I-phosphor enhle iyabiza, futhi i-fluorescing eyengeziwe ilimaza ukusebenza kahle. Ngenxa yalokho, imithombo ye-LED eshibhile ivame ukuba luhlaza okwesibhakabhaka futhi ibe ne-CRI embi.
Ingabe zonke izibani ze-LED ziyi-RGB?
I-RGB LED isho ama-LED abomvu, aluhlaza okwesibhakabhaka naluhlaza. Imikhiqizo ye-RGB LED ihlanganisa le mibala emithathu ukuze ikhiqize ama-hues okukhanya angaphezu kwezigidi ezingu-16. Qaphela ukuthi akuyona yonke imibala engenzeka. Eminye imibala “ingaphandle” kukanxantathu owakhiwe ama-RGB LED.
Uyini umehluko phakathi kwe-white LED ne-RGB LED?
I-RGB isebenzisa umbala omsulwa we-Red/Green/Blue LED's. Uma uzigxilisa ndawonye, zidala ukukhanya okumhlophe kwangempela futhi lokhu okugxilwe kusibonisi kufanele kudale imibala egqamile, eyiqiniso. Ama-LED amhlophe empeleni angamaledi aluhlaza okwesibhakabhaka anephosphor ephuzi, futhi ngaleyo ndlela enza umbono omhlophe.
Iyini i-RGB emhlophe?
Okumhlophe = [255, 255, 255]
Ingabe ukukhanya okumhlophe kwe-LED akulungile emehlweni?
Ucwaningo lwaseSpain lwango-2012 lwathola ukuthi imisebe ye-LED ingadala umonakalo ongalungiseki ku-retina. Umbiko wango-2019 ovela eFrance Agency for Food, Environmental and Occupational Health and Safety (ANSES) uxwayise “ngemiphumela yezithombe” yokuvezwa kokukhanya okuluhlaza okwesibhakabhaka, okufaka nengozi eyengeziwe yokwehla kwamandla emisebe okuhlobene nobudala.
Yikuphi ukukhanya kwe-LED okungcono kakhulu kwamehlo?
Ukukhanya okufudumele kuhle kakhulu emehlweni. Lokhu kuhlanganisa ukukhanya kwemvelo okuhlungiwe nokukhanya okukhiqizwa ama-incandescent namalambu okukhanya e-LED. Sabalalisa ukukhanya endlini yakho nasendaweni yokusebenza ukuze uqinisekise ukukhanya okwanele.
Yikuphi okungcono okumhlophe okufudumele noma okumhlophe okupholile?
Nakuba okumhlophe okupholile kubukeka kukuhle emakhishini esimanje nalapho okucwebezelayo kungcono, okumhlophe okufudumele kusebenza kangcono kakhulu lapho ufuna ukukhanya okuthambile. Ifaneleka kakhulu amagumbi okuphumula, amagumbi okuhlala kanye nekhishi lendabuko, njengezitayela zezwe, lapho ukukhanya okumhlophe kuqhathaniseka kakhulu nalo lonke igumbi.
