Qaphela: I-UGR ecetyisiweyo yi-BSEN12464 ayinyanzelekanga ukuba ilandelwe; yingcebiso nje. Ukwenza ukukhanya okugqibeleleyo, yila ukukhanya kwakho kwaye ukhethe i-UGR ngokusekwe kwiimfuno zesicelo sexesha lokwenyani.
Imida yeNdlela ye-UGR
1. Imida yamaxabiso e-data sheet ye-UGR
Ixabiso olifumana kwiphepha ledatha le-UGR ayiloxabiso elingaguqukiyo lolungiso. Ngokomzekelo, ukuqwalasela ubungakanani begumbi eliqhelekileyo le-4H / 8H kunye nomgangatho wokubonisa i-20%, iindonga ze-50%, kunye ne-70% yesilingi, i-UGR yokukhanya i-19. Kwizicelo zangempela, i-UGR ingaba phezulu okanye ngaphantsi.
2. Imida yendlela yetheyibhuli ye-UGR
Indlela yetheyibhuli ye-UGR isebenzisa ilungiselelo le-luminaire ebonakalayo, hayi izibane zokwenyani. Ngaphandle koko, ubungakanani begumbi kule ndlela bulinganiselwe phakathi kwe-2H kunye ne-12H. Ngoko ke, ayibonisi siphumo sokubengezela kumagumbi amakhulu kuno-12 H okanye amancinci kuno-2H.
3. Imida kubungakanani bemithombo yokukhanya
Indlela ye-UGR ayisebenzi kwimithombo yokukhanya egubungela i-angle eqinileyo engaphantsi kwe-0.0003 sr okanye ngaphezulu kwe-n 0.1 sr. Ke, ukuba izibane ezikhulu zibekwe kwiiholo ezinkulu ezinobude obuphakamileyo, awungekhe ulinganise umphumo welitha ngendlela ye-UGR. Ke, ayisebenzi kwiiwasha zodonga, iisilingi ezikhanyayo, izibane ezilungelelanisiweyo (ezincinci), kunye nezinye iindawo ezincinci okanye ezinkulu kakhulu ezikhanyayo.
4. Imida ngenxa yeenguqu ezibonakalayo ezinxulumene neminyaka kunye nezixhobo zokulungiswa kombono
Kwindlela ye-UGR, amaxabiso abekwe ngokusekwe kumndilili wokuthandwa. Ubudala kunye nemeko yeliso lomntu ngamnye, amaxabiso e-UGR ayahluka; oku kuthintela ukuchaneka kwayo.
5. Imida yeendawo eziphakamileyo
Ngokutsho kwe-CIE 117: 1995, indlela ye-UGR ayisebenzi kwiiholo eziphezulu, umz, ukusuka kwi-7 m ukuya phezulu. Kule meko, ngenxa yokuphakama kwendawo enkulu, umbonisi ubona izikhanyiso kwii-angles ezincinci, eziqinileyo. Kodwa nala ma-engile amancinci avela kwindawo ephezulu ekhanyayo anokubangela ukubengezela okukhulu.
FAQs
Ukuqhawula phezulu
Emva kwazo zonke ezi ngxoxo, ngokuqinisekileyo uye waqonda ukuba i-UGR ayiloxabiso elingaguqukiyo. Itshintsha kwiindlela ezahlukeneyo, ukukhanya okukhanyayo, ubungakanani begumbi, njl. Ngoko ke, ukuba ufuna ukufumana ixabiso elichanekileyo le-UGR yesibane sakho, yiya kuvavanyo lwexesha lokwenyani.
