Ziqaqambe kangakanani izibane zendlela?

Izibane zendlelaziyinxalenye ebalulekileyo yeziseko ezingundoqo eziqinisekisa ukhuseleko ezindleleni. Ezi zibane zinkulu, zide zinika ukukhanya kubaqhubi abahamba kuhola wendlela ebusuku. Kodwa ziqaqambe kangakanani ezi zibane zendlela? Zeziphi izinto ezigqiba ukuqaqamba kwayo?

Ukukhanya kokukhanya kohola wendlela kunokwahluka ngokuxhomekeke kwizinto ezahlukeneyo, kuquka uhlobo lokukhanya, ukuphakama okunyukayo, kunye neemfuno ezithile zendlela. Ngokuqhelekileyo, izibane zendlela yenzelwe ukubonelela ngezinga eliphezulu lokukhanyisa ukuqinisekisa ukhuseleko lomqhubi kunye nokuvumela ukubonakala kwisantya esiphezulu.

Enye yezona zinto zibalulekileyo ezimisela ukukhanya kwendlela yokukhanya luhlobo lokukhanya ngokwalo. Kukho iintlobo ngeentlobo zezibane ezidla ngokusetyenziswa ekukhanyeni kuhola wendlela, ngasinye sinenqanaba lalo lokuqaqamba elahlukileyo. Olona hlobo luqhelekileyo lwesibane olusetyenziselwa ukukhanyisa uhola wendlela zizibane ze-LED, ezaziwa ngokukhanya okuphezulu nokuthembeka. Ezi zibane zikwawonga amandla, nto leyo ezenza zibe lukhetho oludumileyo lokukhanyisa kuhola wendlela.

Umphakamo apho kunyuswe isibane sokukhanya nako kudlala indima ebalulekileyo ekuqinisekiseni ukuqaqamba kwaso. Izibane zohola wendlela ziqhele ukunyuswa kangangeemitha ezingama-30 ukuya kwezingama-40 ngaphezu kwendlela ukuze kugqunywe kakhulu kunye nokukhanya. Lo mphakamo ukwanceda ukuthintela ilitha kwaye usasaze ukukhanya ngokulinganayo ngaphaya kwendlela.

Ukongeza kuhlobo lwesibane kunye nokuphakama kofakelo lwaso, iimfuno ezithile zendlela nazo ziyimiba emisela ukukhanya kwezibane zendlela. Umzekelo, oohola bendlela abanesantya esiphezulu okanye uyilo lwendlela oluntsonkothileyo banokufuna izibane eziqaqambileyo ukuqinisekisa ukuba abaqhubi banokubonakala okwaneleyo. Uyilo oluthile lwendlela, njengokugoba kwendlela kunye nobukho bemiqobo, kuya kuchaphazela iimfuno zokukhanya kwezibane zendlela.

Ke, ziqaqambe kangakanani izibane zendlela? I-Illuminating Engineering Society (IES) iphuhlisa imigangatho yokukhanyisa uhola wendlela echaza amanqanaba okukhanyisa afunekayo kwiindidi ezahlukeneyo zeendlela. Le migangatho isekelwe kuphando olubanzi kwaye yenzelwe ukuqinisekisa ukhuseleko lwabaqhubi kunye nokubonakala. Ngokuqhelekileyo, izibane zendlela yenzelwe ukubonelela ukukhanya okuncinci kwe-1 ukuya kwi-20 lux, kuxhomekeke kwiimfuno ezithile zendlela.

Itekhnoloji yokukhanyisa yenze inkqubela phambili ebonakalayo kwiminyaka yakutshanje, ekhokelela kuphuhliso lwezibane zendlela ezikhanyayo, ezonga amandla. Izibane ezikhanyayo ze-diode (i-LED), ngokukodwa, ziye zaba lukhetho oludumileyo lokukhanyisa uhola wendlela ngenxa yokukhanya okuphezulu kunye nokusebenza kakuhle kwamandla. Izibane ze-LED ziyaziwa nangokuphila kwazo ixesha elide, ukunciphisa iindleko zokugcinwa kwexesha.

Kubalulekile ukuqaphela ukuba ngelixa izibane eziqaqambileyo zohola wendlela zibalulekile kukhuseleko lwabaqhubi kunye nokubonakala, kufuneka zilungelelaniswe ukuthintela ilitha kunye nongcoliseko lokukhanya. Ukukhanya okuvela kwizibane eziqaqambileyo kunokuchaphazela ukubonakala komqhubi, ngelixa ungcoliseko lokukhanya lunokuba nefuthe elibi kwindalo kunye nezilwanyana zasendle. Yiyo loo nto kubalulekile ukuyila ngononophelo kwaye ufake izibane zendlela ukubonelela ngomlinganiselo ofanelekileyo wokuqaqamba ngaphandle kokubangela ilitha elingeyomfuneko okanye ungcoliseko lokukhanya.

Isishwankathelo, izibane zendlela zenzelwe ukubonelela ngezinga eliphezulu lokukhanyisa ukuqinisekisa ukhuseleko kunye nokubonakala kwabaqhubi endleleni. Ukukhanya kokukhanya kohola wendlela kuya kwahluka ngokuxhomekeke kwizinto ezifana nohlobo lokukhanya, ubude bofakelo, kunye neemfuno ezithile zendlela. Njengoko ubugcisa bokukhanyisa buhambela phambili, kulindeleke ukuba kwixesha elizayo sibone izibane eziqaqambileyo, ezonga umbane ngakumbi, siphucula ngakumbi ukhuseleko ezindleleni.

Ukuba unomdla izibane zendlela, wamkelekile ukuba uqhagamshelane TIANXIANG kufumana isicatshulwa.
