Intshayelelo
Xa kuziwa ekukhetheni izibane ze-LED zekhaya lakho okanye indawo yokuthengisa, izinto ezimbini eziphambili zihlala zivela: Isalathiso soMbala woMbala (CRI) kunye nokusebenza kakuhle okukhanyayo. Yomibini le miba ichaphazela kakhulu umgangatho kunye nokusebenza kokukhanya kwiindawo ezahlukeneyo. Kule bhlog, siza kuphonononga ukuba yintoni i-CRI, iwuchaphazela njani umgangatho obonakalayo wokukhanya, kunye nendlela ukuphumelela okukhanyayo okuchaphazela ngayo ukusetyenziswa kwamandla kunye nokusebenza. Ukuqonda ezi mpawu kuya kukunceda wenze izigqibo ezinolwazi xa ukhetha izibane ze-LED.
1. Yintoni i-Colour Rendering Index (CRI)?
I-Color Rendering Index (CRI) yimetric esetyenziselwa ukuvavanya indlela ngokuchanekileyo umthombo wokukhanya utyhila imibala yokwenyani yezinto xa kuthelekiswa nokukhanya kwelanga kwendalo. Kubaluleke kakhulu xa ukhetha izibane zeendawo apho ukuqondwa kombala ngokuchanekileyo kubalulekile, njengeegalari zobugcisa, iivenkile ezithengisayo, iiofisi kunye namakhitshi.
Amanqaku aphambili malunga ne-CRI:
I-CRI Scale: Isikali se-CRI sisuka kwi-0 ukuya kwi-100, kunye ne-100 emele ukukhanya kwendalo (ukukhanya kwelanga) okwenza imibala ngokugqibeleleyo. Okukhona liphezulu ixabiso le-CRI, kokukhona ngokuchanekileyo umthombo wokukhanya ubonisa imibala.
I-CRI 90 okanye ngaphezulu: Ithathwa njengegqwesileyo kuninzi lwezicelo, kubandakanya iindawo zokuthengisa, amagumbi omboniso, kunye neemyuziyam.
I-CRI 80–90: Isetyenziswa ngokuqhelekileyo ekukhanyeni ngokubanzi kumakhaya okanye kwimo yeofisi.
I-CRI engaphantsi kwe-80: Ihlala ifumaneka kwizibane ezikumgangatho ophantsi kwaye ayikhuthazwa ngokubanzi kwiindawo ezifuna unikezelo lombala oluchanekileyo.
Indlela i-CRI ewuchaphazela ngayo uMgangatho wokuKhanya:
Imibala echanekileyo: I-CRI ephezulu iqinisekisa ukuba imibala ibonakala njengoko bekuya kuba njalo phantsi kokukhanya kwendalo. Ngokomzekelo, ukutya kwivenkile okanye iimpahla kwivenkile yokuthengisa kuya kubonakala kunamandla kwaye kukhangayo phantsi kwezibane ezine-CRI ephezulu.
Intuthuzelo ebonakalayo: Ukukhanya okuphezulu kwe-CRI kunciphisa ukugqwetheka kombala, okwenza iindawo ezisingqongileyo zizive zendalo kwaye zikhululekile. Oku kubaluleke kakhulu kwiindawo zokusebenza apho imisebenzi ebonakalayo ifuna ukuchaneka.
2. Yintoni iLuminous Efficiency?
UkuSebenza okuLuminous kubhekiselele kubungakanani bokukhanya okubonakalayo oveliswa ngumthombo wokukhanya kwiyunithi nganye yamandla ewasebenzisayo. Ngokusisiseko, ilinganisa ukuba umthombo wokukhanya uwaguqula njani amandla ombane (watts) ukuba abe luncedo ekuphumeni kokukhanya (lumens). Ukuphakama kokusebenza okukhanyayo, kokukhona ukukhanya kuveliswa ngeyunithi nganye yamandla.
Amanqaku aPhambili malunga noKusebenza ngokuKhanyayo:
Ilinganiswe kwiiLumens ngeWatt nganye (lm/W): Le metric ibonisa ukusebenza kakuhle komthombo wokukhanya. Ngokomzekelo, ukukhanya okuphantsi kunye ne-100 lm / W kuvelisa i-lumens ye-100 yokukhanya kwi-watt nganye yamandla asetyenzisiweyo.
Ukusebenza kakuhle kwe-LED: Izibane ze-LED zanamhlanje zinokukhanya okuphezulu kakhulu, zihlala zidlula i-100 lm / W, oku kuthetha ukuba zivelisa ukukhanya okungaphezulu ngamandla amancinci, zibenza basebenzise amandla xa kuthelekiswa nobuchwepheshe bokukhanyisa bendabuko njenge-incandescent okanye i-halogen.
Indlela UkuSebenza Okuqaqambileyo Okusichaphazela Ngayo Isithuba Sakho:
IMithetho eYilwayo yaMandla asezantsi: Okukhona kukukhanya komthombo wokukhanya, amandla amancinci owufunayo ukukhanyisa indawo, okukhokelela kwiindleko zombane eziphantsi.
Ukuzinza: Izibane ze-LED ezinokukhanya okuphezulu okuphezulu akugcini nje ukugcina imali kodwa zinegalelo ekunciphiseni impembelelo yokusingqongileyo ngokunciphisa ukusetyenziswa kwamandla kunye nokunciphisa i-carbon footprints.
Ubunzulu bokukhanya: Ukusebenza okuphezulu okukhanyayo kuqinisekisa ukuba neendawo ezinamanzi aphantsi zisenakho ukuqaqamba okwaneleyo. Oku kuluncedo ngokukhethekileyo kwiindawo zorhwebo okanye kumagumbi amakhulu afuna ukukhanya okufanayo kunye nokuqaqambileyo.
3. Indlela i-CRI kunye noKusebenza ngokuKhanyayo okuSebenzayo kunye
Ngelixa i-CRI kunye nokusebenza kakuhle okukhanyayo zizimethrikhi ezahlukileyo, zisebenza kunye ukumisela umgangatho opheleleyo wenkqubo yokukhanyisa. Umthombo wokukhanya ophakamileyo kwi-CRI kunye nokusebenza kakuhle okukhanyayo kuya kubonelela ngombala obalaseleyo kunye nokukhanya okuqaqambileyo ngelixa usebenzisa amandla amancinci.
Ukuphucula zombini i-CRI kunye nokusebenza ngokufanelekileyo:
Itekhnoloji ye-LED iphuculwe kakhulu kule minyaka idlulileyo, ibonelela ngeemveliso ezinokufezekisa zombini i-CRI ephezulu kunye nokusebenza kakuhle okukhanyayo. Ngokomzekelo, izibane ezininzi ze-LED zanamhlanje zibonelela nge-CRI 90+ kunye ne-lumens nge-watt nganye ye-100+. Ezi zikhanyiso zibonelela ngezona hlabathi zimbini: unikezelo lombala oluchanekileyo kunye nokonga amandla aphezulu.
Xa ukhetha isisombululo sokukhanyisa, kubalulekile ukulinganisa i-CRI kunye nokusebenza kakuhle okukhanyayo ngokusekelwe kwiimfuno zakho zokukhanyisa. Kwiindawo ezifuna ukuchaneka kombala, ezifana nokuthengisa okanye iigalari zobugcisa, i-CRI ephezulu ibalulekile. Ukukhanyisa ngokubanzi apho ukonga amandla kubaluleke kakhulu, ukusebenza kakuhle okukhanyayo kufuneka kube yingqwalasela ephambili.
4. Ukusetyenziswa kwe-CRI kunye nokuSebenza okuLuminous kwii-Downlights ze-LED
Izibane eziphezulu ze-CRI ze-LED:
Iindawo zokuthengisa: Ii-LED eziphezulu ze-CRI zifanelekile kwiindawo zokuthengisa, apho ukubonisa iimveliso ngemibala yazo yokwenyani kubalulekile ekuthengisweni. Unikezelo lombala oluchanekileyo lungundoqo kwiivenkile zempahla, iivenkile zezacholo, kunye neesaluni zobuhle.
Iigalari zoBugcisa kunye neeMyuziyam: Imisebenzi yobugcisa kunye nemiboniso kufuneka ikhanyiswe ngokukhanya okuphezulu kwe-CRI ukuveza imibala yabo yokwenyani kunye neenkcukacha ngaphandle kokuphazamiseka.
Amakhitshi kunye neendawo zokuSebenza: Kwiindawo apho ukwahlukana kwemibala echanekileyo kuyadingeka (njengamakhitshi, iindibano zocweyo, okanye izitudiyo zokuyila), ukukhanya kwe-CRI ephezulu kuqinisekisa ukunikezelwa kombala wokwenene.
Izibane ze-LED eziLungileyo eziLumlekileyo:
Iiofisi kunye neNdawo eziKhulu zoRhwebo: Kwiindawo ezifuna ukukhanya okufanayo kunye nokuqaqambileyo, ukusebenza kakuhle okukhanyayo kuqinisekisa ukonga amandla ngelixa kugcinwa amanqanaba okukhanya ayimfuneko kwimveliso kunye nokuthuthuzela.
Ukusetyenziswa kweKhaya: Izibane ze-LED ezisebenza ngamandla kumakhaya zibonelela ngokukhanya okuqaqambileyo ngaphandle kokunyusa kakhulu iindleko zamandla.
Ukukhanya kwangaphandle: Kwiindawo zorhwebo zangaphandle ezifana neendawo zokupaka okanye iindlela zokuhamba, ukukhanya okuphezulu okukhanyayo kuqinisekisa ukuba iindawo ezinkulu zikhanyiswa ngokufanelekileyo ngokusetyenziswa kwamandla amancinci.
5. Ukukhetha isibane esiLungileyo se-LED kwiiMfuno zakho
Xa ukhetha izibane ze-LED, qwalasela zombini i-CRI kunye nokusebenza okukhanyayo okusekwe kwiimfuno ezithile zendawo:
I-CRI ephakamileyo ibalulekile kwiindawo apho ukuchaneka kombala kubaluleke kakhulu.
Ukusebenza okukhanyayo okuphakamileyo kulungele iindawo ezinkulu okanye zorhwebo ezifuna ukuqaqamba kodwa zisebenzise amandla.
Kwizicelo zokukhanyisa ngokubanzi, ukufumana ibhalansi phakathi kwe-CRI kunye nokusebenza kakuhle kuya kukunika ixabiso elifanelekileyo.
Ukuqukumbela
Zombini iSalathiso sokuBonelelwa koMbala (CRI) kunye nokuSebenza okuLuminous zizinto ezibalulekileyo ekufuneka uziqwalasele xa ukhetha izibane ze-LED kwiiprojekthi zakho zokukhanyisa. Ngokuqonda indlela nganye yezi mpawu ichaphazela ngayo umgangatho wokukhanya, ukusetyenziswa kwamandla, kunye nokuthuthuzela okubonakalayo, unokwenza izigqibo ezinolwazi ngakumbi ukudala indawo efanelekileyo yokukhanyisa indawo yakho.
Nokuba ukhanyisa ikhaya, iofisi, okanye indawo yokuthengisa, ukukhetha i-CRI ephezulu kunye nezibane ze-LED ezonga amandla kuya kukunceda ufezekise ulungelelwaniso olugqibeleleyo lokuqaqamba, ukuchaneka kombala, kunye nokonga amandla.
