Ungazikhetha njani izibane zeFloodlights kwiiNtsika eziPhakamileyo?
Iipali eziphakamileyo zemasti zisetyenziswa kakhulu kwiindawo ezinkulu zangaphandle ezifana neenkundla zemidlalo, iindlela ezinkulu, amazibuko, izikhululo zeenqwelo-moya, kunye neendawo zoshishino. Ezi zakhiwo zinde zezibane zibonelela ngokukhanya okunamandla nokulinganayo kwiindawo ezinkulu. Eyona nto iphambili ekusebenzeni kwazo kuhlobo kunye nomgangatho wezibane ezifakwe kuzo. Ukukhetha izibane ezifanelekileyo zemasti eziphezulu kubalulekile ukuqinisekisa ukhuseleko, ukusebenza kakuhle, kunye nokusebenza kakuhle kweendleko. Nazi ezinye zezinto ezibalulekileyo ekufuneka uziqwalasele xa ukhetha.
1. Iimfuno zokukhanyisa kunye nokusetyenziswa kwazo
Ngaphambi kokukhetha izibane ezikhanyayo, kubalulekile ukuchaza injongo yokukhanyisa. Umzekelo, iimfuno zokukhanyisa kwindlela enkulu zahlukile kwezo zebala lemidlalo. Ukukhanya okufunekayo (okulinganiswe ngee-lumens), i-angle ye-beam, kunye nobushushu bombala kufuneka kumiselwe ngokwesicelo. Umzekelo, amazibuko kunye neendawo zoshishino zinokufuna ubushushu bombala obupholileyo (5000K–6500K) ukuze kucace, ngelixa amabala emidlalo enokuxhamla kwithoni efudumeleyo ukuze kuthomalale ukubonakala.
2. Amandla ombane kunye nokusebenza kakuhle okukhanyayo
Izibane ezikhanyayo ezinemasti ephezulu kufuneka zinike amandla okukhanya aphezulu — ii-lumens ezingaphezulu nge-watt nganye — ukunciphisa ukusetyenziswa kwamandla ngelixa kugcinwa ukukhanya. Izibane ezikhanyayo ze-LED zanamhlanje zisebenza kakuhle kakhulu, zinika i-120 ukuya kwi-160 lm/W. Amandla ombane akhethiweyo kufuneka afanele ukuphakama kwemasti (ngesiqhelo i-20-40 yeemitha) kunye nendawo eza kukhanyiswa. Njengomthetho jikelele, iipali eziphakamileyo zifuna amandla ombane aphezulu.
3. I-Optics kunye ne-Beam Angle
I-engile yemitha ichaphazela indlela ukukhanya okusasazeka ngayo. Ii-engile zemitha ezimxinwa (10°–30°) zilungele ukugxila ekukhanyeni kwiindawo ezithile, ngelixa ii-engile ezibanzi (60°–120°) zisetyenziselwa ukugubungela ngokubanzi. Ukusebenzisa umxube wee-engile zemitha kwinkqubo enye ye-mast ephezulu kunokunceda ukunciphisa izithunzi nokuqinisekisa ukukhanya okulinganayo.
4. Ukuqina kunye nokumelana nemozulu
Ekubeni izibane ezikhanyiswayo ezinde zibonakala kwiindawo zangaphandle, kufuneka zikhuseleke kwimozulu. Khangela izixhobo ze-IP65 okanye ezikumgangatho ophezulu, ezikhuselweyo eluthulini nasemanzini. Ukongeza, izinto ezisetyenziswayo kwizixhobo kufuneka zingabi nagqwala, ingakumbi kwiindawo eziselunxwemeni okanye kwimizi-mveliso.
5. Ukusasazwa kobushushu kunye nexesha lobomi
Ukuchithwa kobushushu ngokufanelekileyo kubalulekile ukuze izibane ze-LED zihlale ixesha elide. Ulawulo olubi lobushushu lunokunciphisa ixesha lokuphila kwaye lunciphise ukusebenza. Khetha izibane ze-floodlight ezinezitshisi zobushushu ze-aluminium kunye noyilo oluhle lomoya. Ixesha elide lokuphila (iiyure ezingama-50,000 nangaphezulu) kunciphisa iindleko zokulungisa, ingakumbi kuba izibane ze-mast eziphezulu kunzima ukuzifikelela.
6. Ulawulo olukrelekrele kunye nokuDimming
Izibane zanamhlanje zihlala zineendlela zokulawula ezikrelekrele, kubandakanya izibali-xesha, izinzwa zokuhamba, kunye nokujonga kude. Ezi mpawu zinceda ukuphucula ukusebenza kakuhle kwamandla kwaye zivumela ulawulo lokukhanya oluguquguqukayo ngokuxhomekeke kwixesha losuku okanye kwinqanaba lomsebenzi.
