Iindaba - ULwazi lwe-LED Isiqendu 1: Yintoni i-LED kwaye yintoni enhle ngayo?

Yintoni i-LED?

I-LED yi-acronym ye-LIGHT EMITTING DIODE, icandelo elikhupha ukukhanya kwe-monochromatic kunye nokuhamba kwamandla ombane.

Ii-LED zibonelela abaqulunqi bokukhanyisa uluhlu olutsha lwezixhobo zokuphuma ukuze bancede bafezekise iziphumo ezilungileyo kwaye baphuhlise izisombululo zokukhanyisa ezinobuchule kunye neziphumo ezimangalisayo ezazikade zingenakwenzeka ukuba zifezekiswe.I-LED esemgangathweni ophezulu kunye ne-CRI> i-90 index ehlelwe kwi-3200K - 6500K nayo ibonakala kwimarike.ezi zamva njeunyakas.

Ukukhanya, i-homogeneity, kunye nonikezelo lombala wezibane ze-LED ziphuculwe kangangokuba ngoku zisetyenziselwa uluhlu olubanzi lwezicelo zokukhanyisa.Iimodyuli ze-LED zinenani elithile lee-diode ezikhupha ukukhanya ezifakwe kwibhodi yesekethe eprintiweyo (eqinile kwaye iguquguqukayo) kunye nezixhobo ezisebenzayo okanye ezisebenzayo zokulawula zangoku.

I-Optics okanye izixhobo zokukhokela ukukhanya nazo zinokongezwa ngokuxhomekeke kwintsimi yesicelo sokufumana iiplanga ezahlukeneyo kunye nokukhanya.Uluhlu lwemibala, ubungakanani obudibeneyo kunye nokuguquguquka kweemodyuli ziqinisekisa uluhlu olubanzi lwezinto ezinokwenzeka zokudala kwizicelo ezininzi.

LEDs: zisebenza njani?

Ii-LED zizixhobo ze-semiconductor eziguqula umbane ube kukukhanya okubonakalayo.Xa inikwe amandla (i-polarization ngqo), ii-electron zihamba nge-semiconductor, kwaye ezinye zazo ziwela kwibhendi yamandla ephantsi.

Kuyo yonke inkqubo, amandla "agciniwe" akhutshwa njengokukhanya.

Uphando lwezobuchwephesha luvumele ukufikelela kwi-200 Im/W kwi-LED nganye yombane ophezulu.Inqanaba langoku lophuhliso libonisa ukuba iteknoloji ye-LED ayikafikeleli ngokupheleleyo.

Iinkcukacha zobugcisa

Sihlala sifunda malunga nokhuseleko lwe-photobiological kuyilo lokukhanyisa.Lo mba ubaluleke kakhulu umiselwa sisixa semitha yemitha ekhutshwa yiyo yonke imithombo enobude obuphakathi kwe-200 nm kunye ne-3000 nm.Ukuba sesichengeni ngokugqithisileyo ngemitha kunokuba yingozi kwimpilo yabantu.Umgangatho we-EN62471 uhlela imithombo yokukhanya ibe ngamaqela omngcipheko.

Iqela loMngcipheko 0 (RGO): iiluminaires zikhululekile kwiingozi ze-photobiological ngokuthobela umgangatho we-EN 62471.

Iqela le-Risk 0 (i-RGO Ethr): ii-luminaires zikhululekile kwiingozi ze-photobiological ngokuthobela umgangatho we-EN 62471 - IEC / TR 62778. Ukuba kuyimfuneko, qhagamshelana nenkonzo yethu yabathengi kumgama wokuqwalasela.

Iqela le-Risk 1 (iqela elinomngcipheko ophantsi): izikhanyiso azifaki nayiphi na ingozi ngenxa yokunciphisa ukuziphatha okuqhelekileyo komntu xa ebonakaliswe kumthombo wokukhanya.

Iqela le-Risk 2 (iqela eliphakathi lomngcipheko): izikhanyiso azifaki nayiphi na ingozi ngenxa yokusabela kwabantu kwimithombo yokukhanya eqaqambileyo okanye ngenxa yokungakhululeki kwe-thermal.

Iqela lomngcipheko

Iinzuzo zokusingqongileyo

Ubomi obude kakhulu bokusebenza (>50,000 h)

Ukukhula ngempumelelo

Ukhuseleko lwe-Photobiological

Izinto eziluncedo kubasebenzisi

Uluhlu olubanzi lwemibala eyahlukeneyo kunye neemodyuli ezihlangeneyo neziguquguqukayo zenza ukuba uninzi lwezisombululo zoyilo kunye noyilo oluyilayo

Iindleko zokuyilungisa ezicuthiweyo

Ukusetyenziswa kwamandla aphantsi, ubomi obude bokusebenza kunye nokugcinwa okuncitshisiweyo kuququzelele ukudalwa kwezicelo ezinomdla
