Izindaba - Ulwazi lwe-LED Isiqephu 1 : Iyini i-LED futhi Yini Enhle Ngayo ?

Yini i-LED?

I-LED isifushaniso se-LIGHT EMITTING DIODE, ingxenye ekhipha ukukhanya kwe-monochromatic ngokugeleza kwamandla kagesi.

Ama-LED ahlinzeka abaklami bokukhanyisa ngohlu olusha lonke lwamathuluzi aphumayo ukuze abasize bathole imiphumela engcono kakhulu futhi bathuthukise izixazululo zokukhanyisa ezihlakaniphile ezinemiphumela emangalisayo ebikade ingenakwenzeka ngokobuchwepheshe ukuyizuza.I-LED yekhwalithi ephezulu ene-CRI>90 index elinganiselwe ku-3200K - 6500K nayo ivele emakethelezi zakamuvaunyakas.

Ukukhanya, i-homogeneity, nokunikezwa kombala kwezibani ze-LED kuthuthukisiwe kangangokuthi manje sezisetshenziselwa izinhlelo eziningi zokukhanyisa.Amamojula e-LED ahlanganisa inombolo ethile yama-diode akhipha ukukhanya afakwe ebhodini lesifunda eliphrintiwe (eliqinile neliguquguqukayo) elinamadivayisi alawulayo asebenzayo noma angenzi lutho.

Ama-Optics noma amadivaysi aqondisayo angabuye angezwe ngokuya ngendawo yohlelo lokusebenza ukuthola imishayo nokukhanya okuhlukile.Izinhlobonhlobo zemibala, usayizi ohlangene kanye nokuguquguquka kwamamojula kuqinisekisa uhla olubanzi lwamathuba okudala ezinhlelweni eziningi.

Ama-LED: asebenza kanjani?

Ama-LED angamadivayisi e-semiconductor aguqula ugesi ube ukukhanya okubonakalayo.Uma inikwe amandla (i-polarization eqondile), ama-electron ahamba nge-semiconductor, futhi amanye awo awela ebhendini yamandla ephansi.

Kuyo yonke inqubo, amandla "agciniwe" akhishwa njengokukhanya.

Ucwaningo lwezobuchwepheshe luvumele ukuzuza u-200 Im/W ku-LED ngayinye yamandla kagesi aphezulu.Izinga lamanje lokuthuthukiswa libonisa ukuthi ubuchwepheshe be-LED abukafinyeleli amandla aphelele.

Imininingwane yobuchwepheshe

Sivame ukufunda mayelana nokuphepha kwe-photobiological ekwakhiweni kokukhanyisa.Lesi sici esibaluleke kakhulu sinqunywa inani lemisebe ekhishwa yiyo yonke imithombo enobude begagasi obuphakathi kuka-200 nm no-3000 nm.Ukuchayeka emisebeni okweqile kungaba yingozi empilweni yomuntu.Izinga le-EN62471 lihlukanisa imithombo yokukhanya ibe ngamaqembu engcuphe.

I-Risk Group 0 (RGO): Izibani zikhululekile ezingozini ze-photobiological ngokuhambisana ne-EN 62471 evamile.

I-Risk Group 0 (RGO Ethr): izibani azikho ezingozini ze-photobiological ngokuhambisana ne-EN 62471 - IEC/ TR 62778 ejwayelekile. Uma kunesidingo, xhumana nesevisi yethu yamakhasimende ngebanga lokubuka.

Iqembu Lengozi 1 (iqembu elinobungozi obuphansi): izibani azifaki ubungozi ngenxa yemikhawulo evamile yokuziphatha yomuntu lapho echayeke emthonjeni wokukhanya.

Iqembu Lengozi 2 (iqembu lengozi eliphakathi nendawo): izibani azibangeli bungozi ngenxa yendlela abantu abasabela ngayo emithonjeni yokukhanya ekhanya kakhulu noma ngenxa yokungakhululeki okushisayo.

Izinzuzo zemvelo

Impilo ende kakhulu yokusebenza (>50,000h)

Ukukhula ukusebenza kahle

Imodi yokuvula esheshayo

Inketho yokufiphaza engenakho ukuhluka kwezinga lokushisa lombala

Ukukhishwa kokukhanya okunombala oqondile okungahluziwe Gcwalisa i-spectrum yombala

Imodi yokulawula imibala enamandla (i-DMX, i-DALI)

Ingavulwa nakumazinga okushisa aphansi (-35°C)

Ukuphepha kwe-Photobiological

Izinzuzo kubasebenzisi

Uhlu olubanzi lwemibala ehlukahlukene kanye namamojula ahlangene futhi aguquguqukayo anika amandla izixazululo eziningi zokuklama ezinobuhlakani nezintsha

Ukwehliswa kwezindleko zokunakekela

Ukusetshenziswa kwamandla okuphansi, impilo ende yokusebenza kanye nokulungiswa okuncishisiwe kusiza ukudalwa kwezinhlelo zokusebenza ezithakazelisayo
