Ingabe kukhanya nakakhuluukukhanya kokudoba, ngcono umphumela wezinhlanzi?
Ngaphambi kokuthi singene kulokho, ake sikhulume kancane mayelana nokukhanya nokukhanya.
Ukukhanya kubhekisela enanini elibonakalayo lokukhanyisa (reflection) endaweni ekhanyayo ebusweni bomzimba okhanyayo (isibonisi).Iso lomuntu libheka umthombo wokukhanya usuka ohlangothini olulodwa, futhi isilinganiso samandla okukhanya kule ndawo kuya endaweni yomthombo wokukhanya “ebonwa” ngeso lomuntu sichazwa njengeyunithi yokukhanya komthombo wokukhanya, okungukuthi, ukukhanya. umfutho okhanyayo endaweni ehlongozwayo.Iyunithi yokukhanya yi-Candela ngemitha yesikwele (cd/m2).Ukukhanya yindlela umuntu abona ngayo amandla okukhanya.Isamba se-subjective.Uma kuxoxwa ngesihloko sesibani sezinhlanzi, ngoba ukukhanya kuhloswe kakhulu emehlweni ezinhlanzi, ngicabanga ukuthi akufanelekile ukusebenzisa ukukhanya ukuze kuhlolwe.Isibani sokudoba se-1500w sensimbi ye-halide.Kunalokho, kufanele sisebenzise ukukhanya kwemisebe, noma ukukhazimula ngamafuphi.
Ukukhanya kwemisebe yinani elibonakalayo elimelela amandla emisebe yephoyinti emthonjeni wemisebe ongaphezulu endaweni ethile.Isho amandla asakazwa umthombo wemisebe endaweni kanye neyunithi ye-engeli eqinile ngokusebenzisa isici sendiza eqondile indlela evamile ngesikhathi seyunithi, okungukuthi, ukugeleza kwemisebe yomthombo wemisebe endaweni eklanyelwe iyunithi kanye neyunithi ye-Engeli eqinile.Iyunithi ngama-watts /(spheroidum m 2)
Ukukhanya kuvame ukusho ukushuba kokukhanya, okubhekisela ekugelezeni kokukhanya okubonakalayo okutholwe endaweni yeyunithi ngayinye futhi kukalwa nge-Lux noma i-Lx.Lapho ukukhanya okukhanyayo endaweni eyimitha-skwele engu-1 kuyi-lumen engu-1, ukukhanya kwayo kuyi-lux engu-1.1Lux=1Lm/m2.Ngokusobala, umqondo wokukhanya usekelwe futhi ekuboneni okuzimele kweso lomuntu.Lapho uhlolaisibani se-metal halide squid sokudoba, kufanele kusetshenziswe ukukhanya okukhazimulayo.Ukukhanya okukhazimulayo, okwaziwa nangokuthi i-irradiance, ukugeleza okukhazimulayo endaweni yeyunithi yendawo eveziwe, ngama-watts ngemitha yesikwele (W/ square metres).Kodwa-ke, idatha yamanje yocwaningo ku-phototaxis yezinhlanzi isekelwe kakhulu ekukhanyeni okuhlobene nokubona komuntu.Kule ngxoxo, idatha namayunithi ahlobene nokubona komuntu asasetshenziswa, okufanele alungiswe kahle ngokuya nge-wavelength nezinye izici ekusetshenzisweni kwangempela.
Ngokuvamile, iningiamalambu okudoba angaphansi kwamanzi aphezuluebusuku ukukhanya okufanele akukho ngaphezu kwe-20Lux, ukukhanya kungaphezu kuka-0.01Lux kukhanga ukudoba.Uma u-30% wokukhanya kwesibani se-halogen ukhanyiswa ngaselwandle, ingxenye yokukhanya ingangena emanzini ngokucabangela i-Engeli.Inani eliphelele lama-lumens ohlelweni lokukhanya lwesikebhe lilinganiselwa ku-21 trillion lumens, okusho ukuthi inani1000 watt metal halide izibaniimayelana ne-200 kuya ku-300. Qhubeka nokwandisa inani lesibani sokudoba, uthuthukise ukukhanya kwesikebhe sesibani, ukuthuthukisa umphumela wokuqoqwa kwezinhlanzi akuwona usizo oluningi !!(ngaphandle kokuthi amandla kanye nenani lezibani kunyuswa ngesikhathi esifanayo, kukhuphula ukuphakama kwezibani ezilengayo).
Kulinganiselwa ukuthi kuhlala kuphi izinhlanzi?Uma izibani zikhanya isikhathi eside ngokwanele, izinhlanzi zizohlala cishe ngamamitha ayi-100 futhi ngokuvamile ngeke zisondele.
Umphumela wengxoxo yesihloko sesibili: inani eliphelele lama-lumens weukukhanya kwesikebhe esikhanyayouhlelo imayelana 21 trillion lumens, okungukuthi, inani 1000W izibani zegolide halide imayelana 200-300.Qhubeka nokwandisa inani lesibani sezinhlanzi, uthuthukise ukukhanya kwesikebhe sesibani, ukuthuthukisa umphumela wokuqoqwa kwezinhlanzi akuwona usizo oluningi !!(ngaphandle kwalapho ukwandisa amandla kanye nenani lezibani ngesikhathi esifanayo, phakamisa ukuphakama kwezibani ezilengayo, futhi ushintshe i-Angle yezibani ezilengayo).
