Uyilo lokukhanya kwetonela
Ngenxa yokuba icandelo ngalinye letonela lineemfuno ezahlukeneyo zokukhanya, indlela ezibekwe ngayo izibane nayo yahlukile. Amacandelo asisiseko (amacandelo angaphakathi) ngaphakathi kwetonela ahlelwe ngamaxesha alinganayo, kwaye amacandelo ekungeneni kunye nokuphuma kufuneka ahlelwe ngamaxesha ahlukeneyo ngokweemfuno zokukhanya kunye neemeko zezibane ezikhethiweyo.
Ukhetho lokukhanyisa itonela
Imithombo yokukhanyisa yemveli efana nezibane ze-incandescent, izibane ze-metal halide, izibane ze-sodium ezinoxinzelelo oluphezulu, izibane ze-sodium ezinoxinzelelo oluphantsi, kunye nezibane ze-mercury ezinoxinzelelo oluphezulu zineengxaki ezinje ngeebhanti zokukhanya ezincinci, ukukhanya okungahambi kakuhle, ukusetyenziswa kwamandla aphezulu, kunye nobomi obufutshane. I-span, ekhokelela ngokuthe ngqo kwiziphumo ezibi zokukhanya kwiitonela zendlela. Ayinakuhlangabezana neemfuno zokukhanyisa kwiitonela zohola wendlela, ichaphazela kakhulu ukhuseleko lokuqhuba.
Izibane zokukhanyisa kwitonela kufuneka zihlangabezane nezi mfuno zilandelayo:
1. Kufuneka ibe nedatha epheleleyo yefotometric kwaye yenze uyilo lwenzululwazi nolunengqiqo;
2. Ubuncinci ukuhlangabezana neemfuno zomgangatho wokhuseleko we-IP65;
3. Iindawo ezidibeneyo zesibane kufuneka zibe namandla aneleyo omatshini ukuhlangabezana neemfuno zokumelana nokuzamazama komhlaba;
4. Izinto eziphathekayo kunye neengxenye zesibane kufuneka zibe nokumelana nokugqwala kunye nokumelana nokugqwala;
5. Ubume besibane kufuneka bubonelele lula ukugcinwa nokutshintshwa.
