Ecucuza Luminous - Iyini?

Amandla ngokukhanya okubonakalayo, balinganisela lokujabulela iso womuntu futhi ulinganiswa lumens - okukhipha ukukhanya. Lona amandla okunika yimuphi umthombo wokukhanya.

wavelength

Amandla we umthombo wokukhanya sidlula Babechichima amagagasi kagesi. ecucuza Luminous - kuba isilinganiso sabo, okunikeza ulwazi mayelana amandla ukuvutha umthombo. amagagasi Energy ukukhanya ehlweni lomuntu ubona ehlukile. Nombono ka 0.55 microns e umbala oluhlaza ibonwa okuningi namandla kunomFilisti elibomvu nge ubude 0,63 microns. Esikhathini uhla emisebeni ultraviolet infrared amehlo ethu abanamandla.

Yingakho izimfanelo nombono ka yokucucuza elikhanyayo kubaluleke kangaka. Uma ucabangela ezifweni esweni ngu efingqa yamaza, sithola ukubaluleka kwesejwayelekile. ecucuza Luminous - lingamandla kuyinsakavukela we zamandla akhishwa imisebe yalo, okulinganiselwa ngenxa lokujabulela ukukhanya. Ukukhetha umthombo wamandla ukukhanya, umuntu okuhambisana namandla alo okulingana. Ngokwesibonelo, uma kudingeka esikhundleni izibani incandescent ne LED. Kulokhu, kubalulekile ukuba recalculate okukhiphayo ukukhanya.

Indlela ukukwenza

ecucuza Luminous - iyona ingxenye main ngale ndlela. Ngesikhathi esifanayo dvadtsativoltnoy esikhipha isibani ke zazilingana 250 lumens. Uqinisile yokucucuza efanayo elikhanyayo sezibani LED anganikeza Watts ezimbili noma ezintathu, futhi Fluorescent - eziyisihlanu kuya kweziyisikhombisa. Ngakho, izinzuzo izibani LED ingaphezu sobala.

Ake sithi kudingeka umthombo elikhanyayo okukhipha ecucuza ka lumens 400. Isibani intambo kuyakuba sorokavattnoy, isibani Fluorescent kungaba kusuka Watts eziyishumi kuya nantathu LED - emine noma emihlanu. Noma, ngokwesibonelo, sidinga ecucuza enamandla elikhanyayo sezibani - 2500 lumens. Tungsten ayikwazi ukuba Kulokhu esingaphansi dvuhsotvattnoy, Fluorescent - ayisithupha kuphela ayisishiyagalombili watt LED ngisho kancane - kuphela amabili nanhlanu noma amashumi amathathu.

Yiziphi izibani

Ubukhulu yanoma yimuphi input amandla isibani ulinganiswa Watts (W). Ekuphileni kwethu kwansuku zonke, isetshenziswa, isibonelo, LED izibani kusukela Watts omunye kwabayishumi, kanye ukukhanyisa ongaphandle, badinga enamandla kakhulu - kukhona abangaphezu kwekhulu Watts. Kodwa kumelwe wazi ukuthi amandla isibani ephawula ngesilinganiso energy ukusetshenziswa, umqondo okujula ukuphendula engawuboni kuphela.

Kukhona kungenziwa libhekene eyodwa noma komunye umthombo kuphela iyunithi ecucuza elikhanyayo, okuyinto kulungiselelwa ehluke ngokuphelele. It is hhayi ulinganiswa Watts futhi lumens. Ngisho akuzona zonke nomkhiqizi isibani kahle ucacise ongakhetha kuzo. Ngokwesibonelo, ilebula on the isembozo: yokucucuza elikhanyayo of 280 lumens i amandla isibani LED ukuze Watts ezine, obulingana pyatidesyativattnoy esikhipha isibani. Bheka ithebula: in the sakamuva ecucuza elikhanyayo akuyona 280, futhi wonke 560 LM kufanele kube. Wakwenza njani lokho?

izibalo

Iyunithi ecucuza elikhanyayo is inesikhala ukugeleza lapho likhipha endaweni blackbody ka 0,5305 mm ² ezingeni lokushisa eliphezulu kakhulu - 1773 ° C, lapho Uqinisa-platinum, isibonelo. umfutho ukukhanya - ukuminyana ekucucuzeni elikhanyayo ngomqondo kwendawo, kubalulekile ukucabangela indlela okukhipha ukukhanya kuhlobene nezinga ubukhulu bale engela okuqinile (engela okuqinile - ingxenye isikhala lapho bonke imisebe bukhomba). Ngakho: iyunithi okujula elikhanyayo - hhayi lumens futhi Candela.

Kuyini okukhanyisa? Lokhu kungenziwa ngokuthi surface ukuminyana ecucuza elikhanyayo okungukuthi sigameko phezu, ilingana ratio yokucucuza elikhanyayo usayizi ebusweni esikhanyayo, lapho ngokulinganayo basakaza. Ngo okukhanyisa Ubuye iyunithi ayo zokulinganisa, futhi hhayi inesikhala futhi. Futhi ukwenza ngisho Candela. Lokhu lux (LX). Yikuphi okuyoba ukuba alingana nengxenye suite, uma okukhipha ukukhanya ilingana komunye inesikhala, basakaza ngokulinganayo phezu endaweni eyodwa imitha sikwele? Kodwa: 1 lux = 1 LM / 1m ^2.

Ukukhanya likhanya ngendlela efanayo

Ukusakaza Khanyisa kungenzeka ukugqama ezahlukene kanye svetnosti (likhanya ngendlela efanayo). Ukugqama - iyona nokulingana kwabantu ebusweni umfutho elikhanyayo nokuxhumana kwalo isikhala, afakwa ebusweni elikhanyayo ebhanoyini perpendicular lesi siqondiso. Iyunithi ukugqama ubhekwa omunye Candela per imitha square (1 cd / m ^2).

Svetnost (noma iLuminance) is kwabantu yokucucuza elikhanyayo okuyinto Likhipha ebusweni Illuminated. Kuyinto njalo ulingana yokucucuza elikhanyayo ngenhlonipho endaweni yaleli ebusweni. Likhanya ngendlela efanayo futhi, has iyunithi ayo 1 LM / m ^2.

yokucacisa ukufana

Isici ukusetshenziswa ekucucuzeni elikhanyayo indlela ukubala ukufana kungakhanyi ukukhanya kwezindaba zonke evele ovundlile, kungakhathaliseki ukuthi hlobo izibani. essence yayo wukuthi Coefficient ibalwa igumbi ngalinye, uma sicabangela imingcele yayo eziyisisekelo futhi izakhiwo izinto Retro-kokuphothula. Lena izibalo sasivumela isikhathi akuzona olunembile kakhulu ngokwanele, kodwa le ndlela is kabanzi at zasendlini ukukhanyisa ukuhlelwa.

Umthamo egumbini njalo has uhlobo oluthile ekuvikeleni ebusweni, okuyinto lizobonisa yokucucuza ukukhanya okuvela emthonjeni. Lokhu odongeni, ophahleni, phansi fenisha kumbe impahla yokusebenza asegunjini. Zonke ebusweni ehlukile kuveza okuza, nge value ephakeme noma ngaphansi. Bala inani lamadivayisi ukukhanyisa, hhayi ikhumbula ukugeleza kubonakala kungenzeka kuphela nokungaqiniseki ezinkulu.

okulinganisiwe ingxenye

Okokuqala akhethiwe imithombo ukukhanya izibani uhlelo, ezikhethiwe izinhlobo zalapho for nesikhala esinikeziwe - yokuhlala noma ehhovisi, bese ukubala wenziwa. Injongo yalo iwukuba ukucacisa inombolo luminaires. Kulandzelana kwalokucuketfwe lokuhleliwe ukubala engenziwa ngokuvumelana scheme:

1. Ukukhethwa kohlelo ukukhanyisa.

2. Ukuqondanisa of ukuzinza ekukhanyeni into.

3. Ukukhethwa umthombo ukonga kakhulu yokukhanya.

4. Ukukhethwa uhlobo okunengqondo isibani.

5. Ukuhlolwa isici ukuphepha kanye Coefficient bokungafani sokukhanyisa ke.

6. Ukuhlolwa reflectance ezishelelayo egumbini.

7. Ukubalwa egumbini Inkomba.

8. Ukunqunywa Coefficient ukusetshenziswa ukukhanya.

9. Ibala inani zalapho ezonikeza okukhanyisa edingekayo into.

10. Yenza indaba emfushane ka indawo zalapho usebenzisa uhlelo phansi (ucacise usayizi).

ukukhanyisa uhlelo

Kuba nzima nakakhulu ukubala izibani ukusebenza, ngoba ngokuvamile kakhulu it is kuhlanganiswe. Ngokwesibonelo, e izitshalo yokukhiqiza kuyinto Ukusabalala wendawo eyodwa kuphela kunqatshelwe ngokomthetho. Khetha ukukhanya ubukhulu owesincane umehluko ohlelweni into, okusho zokuqinisekisa ukunemba kwayo yonke indalo ekhona ezibukwayo, ukuze kwenziwe egumbini.

Kukhona imithetho: umsebenzi ngowokuqala ibhithi lesithupha abazenzi kuphela lapho kuhlanganiswe okukhanyisa uhlelo. Lokhu workshop, mechanical, Instrumentation, inhlangano kanye nokunye okufana nalokho. Kuphela izimboni ezifana Electroplating noma ekubunjweni singasetshenziswa jikelele ukukhanyisa uhlelo. Ngakho-ke, ukukhetha uhlelo kanye nemithetho sokukhanyisa kanyekanye.

illuminance kwesejwayelekile

ukukhanyisa Artificial izinkomba ambalwa kanye qualitative kunqunywa ngokuhambisana esiqinile imithetho esebenzayo njalo zokukhiqiza uhlobo lomsebenzi.

izici quantitative yokukhanya wathola ezansi surface ngamunye usebenza kuye ukudedelwa imisebenzi ezibukwayo, i-contrast futhi into ngemuva ohlelweni okukhanyisa. Ukudedelwa kunqunywa ubukhulu eyodwa into (imininingwane), ingxenye noma isici esincane kuso esebenza kuyodingeka ukuthola abuye ahlukanisa phakathi imisebenzi yayo. Eliphezulu ukukhanyisa ukusebenza - ngezinga elithile ukukhanya futhi yezwakala.

imithombo Khanyisa: ngobuhle nangobubi bawo

Indlela ukucacisa imingcele yokukhetha engabizi futhi ngesikhathi esifanayo imvelo umthombo wokukhanya? On isinqumo kungase kuthinte izici eziningi, njenge: isixazululo ukuhlela, ubungcweti, ukwakhiwa imingcele, emoyeni imvelo kanye nesimo salo, kwabanye kwezomnotho kanye, yebo, design. Umklami, ukuklama ukukhanyisa, njalo uya ukusilela, ikhumbula nemingcele eziningi izibalo.

Ngokwesibonelo, ngesibani esikhipha akuyona ukonga kakhulu, awayona eliphezulu kakhulu ukusebenza kahle elikhanyayo, ekushayweni spectrum ehlanekezelwe emsebenzini, bathola kushisa kakhulu futhi ngokushesha behluleka. Nokho, izindleko kubo sincane kakhulu, zingabantu kulula ukusebenzisa konke, kodwa ngoba amakamelo lapho abantu bahlale okwesikhashana, yasendlini nokunye okunjalo, izibani incandescent kungenziwa Kunconywa. Fluorescent ukukhanya okukhipha futhi abe aphakeme, ukuphila isikhathi eside, kakhulu umbala ukuhumusha, ukungabi bafudumale. Kodwa isibani endleleni enjalo futhi zidinga inkonzo Ochwepheshe. izibani switchgear Fluorescent liyinkimbinkimbi kakhulu, ngezinye izikhathi flash futhi ukubhonga, futhi abanazo eziyinkinga.
