Imboni ye-LED iyimboni enamasu kazwelonke asafufusa, futhi umthombo wokukhanya we-LED ungumthombo wokukhanya omusha othembisa kakhulu ekhulwini lama-21, kodwa ngenxa yokuthi ubuchwepheshe be-LED busesesigabeni sokuthuthuka sokuvuthwa okuqhubekayo, imboni isenemibuzo eminingi mayelana nekhwalithi yayo yokukhanya. izici, leli phepha lizohlanganisa ithiyori nokusebenza, lihlaziye isimo samanje se-LED kanye nesiqondiso sokuthuthukiswa kwesikhathi esizayo, sikhuthaze ukuthuthukiswa okunempilo kwemboni ye-LED.

Isimo sokuthuthukiswa kwemboni ye-LED namathrendi

a.Ngokombono womjikelezo womkhiqizo, ukukhanya kwe-LED kungene esikhathini esivuthiwe kakhulu.

Njengamanje, izibani ze-LED, kungakhathaliseki ukuthi zikhanya ngaphandle, noma inkambu yokukhanyisa ezentengiselwano, zingena ngesivinini esishaqisayo.

Kodwa kulesi sigaba, indawo yokukhanya yasekhaya ingachazwa njengesikhwama esixubekile, imikhiqizo ephansi yokukhanya kwe-LED ephansi ingabonakala yonke indawo.Ukukhanyisa kwe-LED kusabambelele ekongeni amandla, ukuvikelwa kwemvelo kanye nempilo ende yezibani.Ngakho-ke, lokhu kuphinde kuholele kubakhiqizi abaningi bezibani ze-LED ukuthi baphishekele ukusebenza kahle okuphezulu kokukhanya kanye nokuncintisana kwezindleko eziphansi, kuyilapho beshaya indiva i-LED empilweni yomuntu nokunethezeka kanye nezici zokukhanyisa ezihlakaniphile zezinhlelo zokusebenza ezisezingeni eliphezulu.

b.Ikuphi indlela yesikhathi esizayo yemboni ye-LED?

Ukusebenza kahle kokukhanya kuzoqhubeka nokuqhubekisela phambili emisha yezobuchwepheshe, okuyinqubo engenakugwenywa yokuthuthukiswa kwempahla, ngenkathi yokukhanyisa okuholwa yi-LED, ngoba umthombo wokukhanya unezinhlobonhlobo zepulasitiki, ukuphishekela ikhwalithi yokukhanya nakho kuyathuthuka.

Ngokombono ophelele, imboni ye-LED okwamanje isesigabeni sokuthuthuka kancane, akusekho ukuqanjwa kabusha kwezobuchwepheshe okuholela embonini ehilelekile empini yamanani, empini yamanani ngokuya ngokushisa okumhlophe, okuphoqelela imakethe kukhwalithi, ukuhlakanipha nokunye. izikhombisi-ndlela.

Kuyini "ukukhanya" ngekhwalithi?

Esikhathini esidlule, izibani ze-LED ezikhanyayo, ukusebenza kahle kokukhanya okuzinzile, njll., isibani sekhwalithi esihle.Kulezi zinsuku, ngomqondo wokukhanya okuluhlaza futhi ogxilile ezinhliziyweni zabantu, izinga lencazelo yekhwalithi yokukhanya enhle kakhulu selishintshile.

a.Isigaba sokuwina ngobuningi sesidlulile, futhi isikhathi sokuwina ngekhwalithi sesifikile.

Lapho sisebenzela amakhasimende aseNyakatho Melika, sithole ukuthi izidingo zawo zekhwalithi yokukhanya kwe-LED ziya ngokuya ziba phezulu.I-North American Lighting Commission IES icacise indlela entsha yokuhlola i-TM-30 yekhono lokunikeza umbala wemithombo yokukhanya, iphakamisa izinkomba ezimbili ezintsha zokuhlola i-Rf ne-Rg, ebonisa ngokugcwele ukuthi ozakwabo bamazwe ngamazwe baqhubekisela phambili ucwaningo olukhanyayo lwe-LED.I-Blue King izokwethula ngokushesha izindlela ezinjalo zokuhlola e-China, ukuze abantu baseShayina bakwazi ukujabulela ngokugcwele umthombo wokukhanya we-LED wekhwalithi ephezulu.

I-TM-30 iqhathanisa amasampula ombala angu-99, amele imibala ehlukahlukene evamile engabonakala ekuphileni (kusuka kokugcwele kuya kokungagcwalisiwe, kusukela kokukhanyayo kuye kokumnyama)

Ishadi lombala we-TM-30

b.Ukufuna kuphela ukukhanya kwekhwalithi yokukhanya kwe-LED okungaletha induduzo kubasebenzisi.

Imikhiqizo yokukhanyisa kwe-LED yekhwalithi ephezulu ngenxa yokugxila kwezempilo, ukubonisa okuphezulu, imiphumela yokukhanya engokoqobo, ukuze imikhiqizo ehlukene ikhethe izinga lokushisa elifanele lombala, namalambu abe nezidingo ezimelene nokucwebezela, alawule izingozi zokuchichima kokukhanya okuluhlaza okwesibhakabhaka, ngamasistimu ahlakaniphile. ukulawula ukukhanyisa, ukuhlangabezana nezidingo zokulawula ezihlakaniphile nezicebile.

c.Ukubola kokukhanya kwe-LED

Ngokungafani nezibani zendabuko ezithambekele ekuhlulekeni kungazelelwe ukuqhubeka nokusebenza, izibani ze-LED azivamile ukuhluleka ngokuzumayo.Ngesikhathi sokusebenza kwe-LED, kuzoba nokubola kokukhanya.Ukuhlolwa kwe-LM-80 kuyindlela nenkomba yokuhlola izinga lokugcinwa kwe-lumen yomthombo wokukhanya we-LED.

Ngombiko we-LM-80, ungaveza impilo ye-LED, ku-IES LM-80-08 ejwayelekile Elinganiselwe I-Lumen Maintenance Life;I-L70 (amahora): ibonisa ukuthi umthombo wokukhanya we-lumens ukubola ku-70% wesikhathi sokuqala se-lumens esisetshenzisiwe;I-L90 (amahora): ibonisa ukuthi umthombo wokukhanya we-lumens ubola ukuya ku-90% wesikhathi sokuqala esisetshenzisiwe.

d.Inkomba yokunikeza umbala ophezulu

Inkomba yokunikeza umbala iyindlela ebalulekile yokuhlola ukunikezwa kombala kwemithombo yokukhanya, futhi iyipharamitha ebalulekile yokukala izici zombala zemithombo yokukhanya yokwenziwa, evezwa i-Ra/CRI.

U-Ra, u-R9 no-R15

Inkomba evamile yokunikeza umbala u-Ra uyisilinganiso sika-R1 kuya ku-R8, kanti inkomba yokunikeza umbala i-CRI iyisilinganiso esingu-RI-R14.Asicabangi nje kuphela ngenkomba evamile yokunikeza umbala u-Ra, kodwa futhi sinake inkomba ekhethekile yokunikeza imibala engu-R9 yokubomvu okugcwele, kanye nenkomba ekhethekile yokunikeza umbala engu-R9-R12 yemibala egcwele ebomvu, ephuzi, eluhlaza okwesibhakabhaka noluhlaza sasibhakabhaka, sikholelwa ukuthi lezi. izinkomba zimelela ngempela umthombo wokukhanya we-LED wekhwalithi, kanye nomthombo wokukhanya okhanyisayo wokuthengisa, kuphela uma lezi zinkomba zinamanani aphezulu zingaqinisekisa ukunikezwa kombala okuphezulu kwe-LED.

Ngokuvamile, inani liphakeme, ukusondelana nombala wokukhanya kwelanga, ukusondela kombala wayo wangempela into ekhanyiswayo.Imithombo yokukhanyisa ye-LED enenkomba ephezulu yokunikeza umbala ivame ukukhethwa embonini yokukhanyisa.Imikhiqizo ehlinzekwa yi-Blue View ngokuvamile isebenzisa i-CRI>95 ngokuvumelana nesidingo sekhasimende, engabuyisela ngempela umbala wezimpahla ekukhanyeni, ukuze kuzuzwe okujabulisayo emehlweni futhi kushukumise isifiso sokuthenga sabantu.

e.Ukukhanya Okukhazimulayo

Ngo-1984, i-Illuminating Engineering Society yaseNyakatho Melika yachaza ukucwayiza njengokuzwakala kokucasuka, ukungakhululeki noma ukulahlekelwa ukusebenza okubukwayo endaweni yokubuka okubangelwa ukukhanya okukhulu kakhulu kunalokho iso elingakwazi ukuzivumelanisa nakho.Ngokwemiphumela, ukuxhopha kungahlukaniswa kube ukucwayiza okungajabulisi, ukuxhopha okujwayela ukukhanya kanye nokucwayiza komngcwabo.

I-LED iyinombolo enkulu yephakeji eyi-cylindrical noma eyindilinga, ngenxa yendima ye-convex lens, inokukhomba okuqinile, ukuqina okukhanyayo okunomumo wephakheji ohlukile nokuqina okuncike ekuqondeni kwe-angular: etholakala ohlangothini olujwayelekile lobukhulu obukhulu bokukhanya, i-engeli yokuphambana nendiza evundlile engu-90. lapho uchezuka endaweni evamile ye-engeli engu-θ ehlukile, amandla okukhanya nawo ayashintsha.izici zomthombo wokukhanya wephoyinti we-LED.Ukuze izici zomthombo wokukhanya we-LED zibe nokukhanya okuphezulu kakhulu kanye nezinkinga zokuxhopha zenzeka.Uma kuqhathaniswa nezibani ze-incandescent, izibani ze-fluorescent, izibani ze-sodium ezicindezela kakhulu nezinye izibani zendabuko, isiqondiso se-fiber optic yezibani ze-LED sigxile kakhulu futhi sithambekele ekukhiqizeni ukukhanya okungakhululekile.

f. Izingozi zokukhanya eziluhlaza okwesibhakabhaka

Ngokuduma kwe-LED, ingozi yokukhanya okuluhlaza okwesibhakabhaka ye-LED noma ukuchitheka kokukhanya okuluhlaza okwesibhakabhaka sekuyinkinga okufanele bonke abantu babhekane nayo futhi bayixazulule, futhi embonini yezibani iyafana.

Izinga elisha le-EU jikelele le-luminaire libeka ukuthi uma i-luminaire ehlanganisa i-LED, izibani zensimbi ze-halide nezinye izibani ezikhethekile ze-tungsten halogen ezingakwazi ukukhululwa ekuhloleni ubungozi be-retina kufanele zihlolwe ngokuvumelana ne-IEC/EN62778:2012 “Ukuphepha kwe-Photobiological kwemithombo yokukhanya nezibani izinhlelo zokusebenza zokuhlola ukulimala kokukhanya okuluhlaza okwesibhakabhaka”, futhi akufaneleki ukusebenzisa imithombo yokukhanya enamaqembu ezingozi zokukhanya okuluhlaza okwesibhakabhaka angaphezu kwe-RG2.

Esikhathini esizayo, sizobona izinkampani eziningi kakhulu, zingakhiqizi kuphela imikhiqizo yokukhanyisa i-LED, futhi zingagxili kumingcele ngayinye yomkhiqizo, kodwa zingacabanga ngendlela yokuthuthukisa ikhwalithi yokukhanya ngokusekelwe kuchungechunge lwenani kusukela ekukhiqizeni kuya kulo lonke. ukufezekiswa kwesidingo.Enqubweni yokuthuthukisa, amakhono okuklama izibani, amakhono okwenza ngokwezifiso umkhiqizo, kanye nokusungulwa nokuthuthukiswa kwamakhono okuphendula ngokushesha, kuyinselelo izinkampani okufanele zibhekane nazo.
