Izibani Zokonga Amandla
Phakathi kwesidingo esikhulayo sikagesi kanye nokuqwashisa umphakathi ngezinkinga zemvelo, isihloko sokukhanyisa kwasekhaya sisabalulekile. Sekungamashumi eminyaka, ama-incandescent bulbs abe yisinqumo esivame kakhulu ngenxa yezindleko zawo eziphansi, ukukhanya okufudumele, kanye nokutholakala kalula. Kodwa-ke, ama-incandescent bulbs avamile aziwa ngokusebenzisa amandla amaningi: iningi likagesi alisebenzisayo liguqulwa libe ukushisa, hhayi ukukhanya. Yilapho kwavela khona umqondo ophikisanayo kodwa othakazelisayo: ama-incandescent bulbs asebenzisa amandla amaningi. Kungenzeka yini ukuthi ama-incandescent bulbs asebenze kahle kakhulu? Yibuphi ubuchwepheshe obuwasondeza "ekongeni amandla"? Lesi sihloko sihlola umqondo, intuthuko, izinzuzo, ukubi, kanye namathiphu okukhetha ukukhanya okuhlakaniphile.
Ukuqonda Amabhalubhu Okukhanya Okusanhlamvu kanye Nesizathu Sokuchitha Amandla
Amabhalbhu akhanyayo asebenza ngesimiso esilula. Uma ugesi ugeleza ngentambo (ngokuvamile i-tungsten), uyashisa uze ukhanye futhi ukhiqize ukukhanya. Inkinga iwukuthi, intambo ekhanyayo ikhipha ububanzi bamandla, okuhlanganisa nemisebe ye-infrared, esiyibheka njengokushisa. Lokhu kusho ukuthi amandla amaningi "achithwa" njengokushisa, kuyilapho ingxenye encane iba ukukhanya okubonakalayo.
Ngokuvamile, ukusebenza kahle kwama-incandescent bulbs endabuko kuphansi kakhulu kunobuchwepheshe besimanje bokukhanyisa njengama-LED. Umphumela ubonakala ngokucacile ekusetshenzisweni kukagesi: ukuze kufinyelelwe izinga elithile lokukhanya, ama-incandescent bulbs adinga amandla engeziwe (i-wattage). Ngakho-ke, igama elithi "ama-incandescent bulbs asindisa amandla" livame ukubhekisela hhayi kuma-incandescent bulbs avamile, kodwa ezinhlotsheni ezithuthukisiwe noma ama-bulbs "abukeka njengama-incandescents" ngokwemibala ekhanyayo kanye nezici, kodwa asebenzisa ubuchwepheshe obusebenza kahle kakhulu.
Kusho ukuthini ukuthi “izibani ezikhanyisayo ezonga amandla”?
Emakethe, leli gama lingabhekisela ezintweni eziningana:
1. Isibani se-halogen (i-halogen incandescent)
I-Halogen iwukuthuthukiswa kwesibani esikhanyayo. Isasebenzisa i-tungsten filament, kodwa isibani siqukethe igesi ye-halogen (njenge-iodine noma i-bromine) esekela "umjikelezo we-halogen," okuvumela i-filament ukuthi isebenze emazingeni okushisa aphezulu, okuholela ekuphileni isikhathi eside kanye nokukhanya okukhanyayo nge-wattage efanayo. Uma kuqhathaniswa nezibani ezivamile ezikhanyayo, ama-halogen ngokuvamile asebenza kahle kakhulu, yize esasele ngemuva kwama-LED.
2. Izibani ze-Incandescent ezinomklamo okhanyayo noma ubuchwepheshe bokumboza
Ezinye izinto ezintsha zizama "ukubuyisela" ukushisa kwe-infrared ku-filament kusetshenziswa i-coating ekhethekile (i-infrared coating). Ngokwethiyori, ukushisa okubonakalayo kungasiza ekugcineni izinga lokushisa le-filament, kudinga ugesi omncane ukukhiqiza inani elifanayo lokukhanya. Lolu hlobo lobuchwepheshe luye lwathuthukiswa kumaphrojekthi ahlukahlukene ocwaningo, yize ukusetshenziswa kwalo kungavamile njalo emakethe yokuthengisa.
3. Izibani ze-LED ezinombala ofana nowe-incandescent
Abantu abaningi babiza izibani ze-LED ngokuthi “izibani ezigcina amandla” ngoba zikhiqiza ukukhanya okumhlophe okufudumele okufana nama-bulb akhanyayo (cishe ama-2700K), futhi ama-bulb awo akhiwe njengama-bulb akhanyayo akudala. Nakuba engewona ama-bulb akhanyayo ngokomthetho, ayisisombululo esithandwa kakhulu sokufeza ukukhanya okukhanyayo ngaphandle kokuchitha amandla.
Ngakho-ke, "ukonga amandla" uma kukhulunywa ngezibani ezikhanyisayo kuvame ukusho ukufaka esikhundleni izibani ezivamile ngobuchwepheshe obufana nezici zazo zokukhanya, kungakhathaliseki ukuthi ama-halogen angcono noma ama-LED asebenza kahle kakhulu.
Ukuqhathanisa Okusheshayo: I-Incandescent, i-Halogen, i-CFL, ne-LED
Ukuze kube lula ukuqonda, nansi isibonelo esilula:
– Izibani ezivamile ezikhanyisayo: ukukhanya okufudumele, i-CRI enhle kakhulu (ukunemba kombala), ezishibhile, kodwa ezichitha isikhathi futhi ezihlala isikhathi esifushane.
– I-Halogen: ukukhanya okufana ne-incandescent, ukusebenza kahle okungcono kancane, ukuphila isikhathi eside kune-incandescent, kodwa kusakhiqiza ukushisa okuphezulu.
– I-CFL (isibani sokonga amandla esijikelezayo): ukusetshenziswa kwamandla okuphansi, kodwa ingaqukatha i-mercury futhi ikhwalithi yokukhanya iyahlukahluka.
– I-LED: eyonga kakhulu amandla, ihlala isikhathi eside, ukushisa okuphansi, ukukhetha okubanzi kwemibala kanye namazinga okukhanya, kodwa ikhwalithi yomkhiqizo incike kakhulu kumkhiqizo/umshayeli.
Uma ukonga amandla kuyinjongo yakho eyinhloko, ama-LED ngokuvamile ayisinqumo esingcono kakhulu. Uma ufuna izici zokukhanya kwe-incandescent futhi usafuna ukonga okwengeziwe kune-incandescent evamile, ama-halogen angaba "ibhuloho," yize ukonga kungabalulekile njengama-LED.
Kungani Kusafunwa Imithunzi Yokukhanya Kwe-Incandescent?
Naphezu kokuchitha imali, izibani ze-incandescent ziyathandwa ngezizathu eziningana:
1. Imibala ekhanyayo efudumele nekhululekile
Amabhalbhu akhipha ukukhanya okuqhubekayo, okwenza izinto zibonakale zemvelo ngombala. Lokhu kuvame ukuhlotshaniswa nesimo "esifudumele" sasekhaya.
2. Kukhululekile emehlweni ezimweni ezithile
Ekamelweni lokuphumula, ekamelweni lokulala, noma endaweni yokudlela, ukukhanya okufudumele kuvame ukuthoba kakhulu kunomhlophe opholile.
3. Kulula ukufiphaza (ukufiphaza)
Amabhalbhu amaningi akhanyayo ahlanganiswa kalula ne-dimmer elula. Ama-LED nawo ayafiphala, kodwa adinga umshayeli ohambisanayo kanye ne-dimmer ukuze kuvinjelwe ukufiphala.
Ngenxa yalezi zizathu, izinto ezintsha "ezisindisa amandla" ngokuvamile zifuna ukugcina ikhwalithi yokukhanya kanye nenduduzo ebonakalayo ngenkathi kunciphisa ukusetshenziswa kwamandla.
Indlela Yokukhetha Ukukhanya Okusebenzisa Amandla Ngendlela Efanele "Yokukhanya"
Uma ufuna isimo sokukhanya kwe-incandescent kodwa ungabizi kakhulu, cabanga ngamaphuzu alandelayo:
1. Gxila kuma-lumens, hhayi kuma-watts
I-Wattage ikhombisa ukusetshenziswa kwamandla, hhayi ukukhanya. Ukuze uqhathanise ukukhanya, bheka ama-lumens. Isibonelo, isibani esilinganiselwe cishe ama-lumens angu-800 ngokuvamile silingana nokukhanya ne-incandescent engu-60W (izinombolo zingahluka ngomkhiqizo).
2. Khetha izinga lokushisa lombala (Kelvin) 2700K–3000K
Ukuze uthole umbala okhanyayo, funa ilebula elimhlophe elifudumele elicishe libe ngu-2700K. Uma ufuna umbala ongathathi hlangothi kodwa ofudumele, i-3000K ingafaneleka.
3. Naka i-CRI (Inkomba Yokunikeza Umbala)
Ama-bulb akhanyayo ayaziwa nge-CRI yawo ephezulu. Khetha ama-bulb ane-CRI engu-80 noma ngaphezulu, futhi uma kungenzeka, i-CRI engu-90 noma ngaphezulu ukuze uthole imibala enembile, ikakhulukazi emakamelweni okudlela, emakamelweni e-powder, noma ezindaweni zokubonisa.
4. Qiniseka ukuthi "i-flicker" iphansi
Amanye ama-LED ashibhile anokukhanya okungabonakali okungakhanga amehlo akho ngokushesha. Funa imikhiqizo ekhangisa ukukhanya okuphansi noma usebenzise abashayeli bekhwalithi ephezulu.
5. Uma usebenzisa i-dimmer, qiniseka ukuthi iyahambisana.
Sebenzisa ama-LED afiphazekayo kanye ne-dimmer efanele. Inhlanganisela engalungile ingabangela ukukhazimula, ukubhonga, noma ukungasebenzi kahle kwesibani ngaphambi kwesikhathi.
6. Cabanga ngesimo sebhalbhu
Ama-LED amaningi esimanje afika ngesimo sama-bulb akudala (A60), amakhandlela, noma ama-filament e-LED abukeka njenge-filament e-incandescent. Lawa afanelekela izibani ezilengayo zokuhlobisa.
Londoloza Amandla Hhayi Ezibanini Kuphela
Ngaphandle kokushintsha izibani, ukonga ugesi kungatholakala futhi ngemikhuba nokuklama:
– Sebenzisa ukukhanyisa okusekelwe endaweni: vula izibani kuphela ezindaweni ezisetshenziswayo.
– Khulisa ukukhanya kwemvelo: vula amakhethini, sebenzisa imibala egqamile yodonga.
– Sebenzisa isibani esifanele: umthunzi obonakalisa ukukhanya kahle ungandisa “umuzwa wokukhanya” ngaphandle kokwengeza amandla.
– Hlanza njalo i-armature: uthuli esivalweni nasesibanini kunciphisa ukukhanya.
Ngaleli cebo, isidingo samandla sokukhanyisa singancishiswa ngaphandle kokulahlekelwa induduzo.
Isiphetho
Igama elithi "Ama-Incandescent Bulbs Asebenza Kahle Ngamandla" lichaza umgomo wokufeza izici ezifudumele nezinembile zokukhanya kwe-incandescent, kodwa ngokusetshenziswa kwamandla okuphansi. Empeleni, izinketho ezivame kakhulu ama-halogen bulbs (asebenza kahle kakhulu kunama-incandescent bulbs avamile) noma ama-LED anombala we-incandescent (awonga kakhulu futhi ahlala isikhathi eside). Uma ukhetha isimo sokukhanya kwe-incandescent, khetha i-LED emhlophe efudumele engu-2700K ene-CRI ephezulu kanye nomshayeli omuhle. Ngale ndlela, ungagcina isimo esifudumele ekhaya lakho ngenkathi wonga ezindleleni zikagesi futhi unciphisa umthelela wakho emvelweni.
Uma ungathanda, ngingakusiza ukuthi ulungise lesi sihloko sibe ngamagama ayi-1000 afaneleka kakhulu (okwamanje siseduze ne-1000), noma usiguqule sibe yinguqulo yesayensi/ethandwa kakhulu, enezibonelo zokubala ukonga izindleko zikagesi.
