Ko kupenya kwakanyanyachiedza chekuredza, zviri nani kuita hove?
Tisati tapinda mune izvozvo, ngatimbotaura zvishoma pamusoro pekupenya uye kupenya.
Luminance inoreva huwandu hwemuviri hwekupenya (reflection) kusimba pamusoro pemuviri unopenya (reflector). Ziso remunhu rinotarisa kunobva mwenje kubva kune imwe nzira, uye chiyero chekusimba kwechiedza munzvimbo iyi kune nzvimbo yechiedza "inoonekwa" neziso remunhu inotsanangurwa sechikamu chekupenya kwechiedza, ndiko kuti, kupenya kwesimba pane iyo unit yakarongwa nzvimbo. Iyo unit yekupenya ndeye Candela pa square mita (cd/m2). Kupenya maonero emunhu ekusimba kwechiedza. Iyo inoenderana nehuwandu. Kana tichikurukura nyaya yerambi rehove, nekuti mwenje unonyanya kunangana nemeso ehove, ndinofunga hazvina kufanira kushandisa kupenya kuongorora.1500w simbi halide hove rambi.Pane kudaro, tinofanira kushandisa kupenya kwemwaranzi, kana kupenya kwenguva pfupi.
Radiation luminance ihuwandu hwemuviri hunomiririra kusimba kwemwaranzi yenzvimbo pane imwe nzvimbo yemwaranzi yemwaranzi mune imwe nzira. Zvinoreva simba rinovhenekerwa nemwaranzi sosi panzvimbo yeyuniti uye unit solid Angle kuburikidza neyakatwasuka plane element yakajairika muunit time, kureva, radiation flux yemwaranzi sosi pane unit yakarongwa nzvimbo uye unit solid Angle. Iyo unit ndeye watts /(spheroidum m2)
Kupenya kunowanzo reva kusimba kwechiedza, izvo zvinoreva kuyerera kwechiedza chinooneka chinotambirwa panzvimbo yeyuniti uye chinoyerwa neLux kana Lx. Kana iyo inopenya inoyerera pamusoro penzvimbo ye 1 sikweya mita iri 1 lumen, kupenya kwayo i1 lux. 1Lux=1Lm/m2. Zviripachena, iyo pfungwa yekuvhenekera zvakare yakavakirwa pane subjective maonero eziso remunhu. Paunenge uchiongororasimbi halide squid hove rambi, chiedza chinopenya chinofanira kushandiswa. Radiant illuminance, inozivikanwawo se irradiance, ndiyo inopenya inoyerera pane yeyuniti nzvimbo yenzvimbo yakashama, mumawatts per square metre (W/ square metres). Nekudaro, iyo yazvino data yekutsvagisa pane phototaxis yehove inonyanya kuenderana nechiedza chine chekuita nekuona kwevanhu. Muhurukuro iyi, data uye zvikamu zvine chokuita nekuona kwevanhu zvichiri kushandiswa, izvo zvinofanirwa kugadziriswa zvakakodzera maererano newavelength nezvimwe zvinhu mukushandiswa chaiko.
Kazhinji kutaura, vazhinjihigh wattage Underwater hove magetsihusiku kuvhenekera kwakakodzera hakusi kudarika 20Lux, kuvhenekera kunopfuura 0.01Lux inokwezva hove. Kana 30% yemwenje wehalogen yakavhenekerwa yakananga kugungwa, ipapo hafu yechiedza inogona kupinda mumvura ichifunga nezveAngle. Huwandu hwemalumens muhurongwa hwechiedza hwechikepe hunosvika 21 trillion lumens, zvinoreva kuti nhamba ye1000 watt simbi halide mwenjeinenge 200 kusvika 300. Ramba uchiwedzera nhamba yerambi rehove, uvandudze kupenya kwechikepe chemwenje, kuvandudza kushanda kwekuunganidza hove hakusi rubatsiro rwakanyanya !! (kunze kwekuti simba uye nhamba yezviedza zvinowedzera panguva imwe chete, kusimudza kukwirira kwezviedza zvakarembera).
Madhiri anofungidzirwa kugara kupi? Kana magetsi akabatidzwa kwenguva yakareba zvakakwana, hove dzinogara kure nemamita zana uye kazhinji hadziswedere pedyo.
Mhedzisiro yekukurukurirana kwechinyorwa chechipiri: iyo yakazara nhamba yelumens yechiedza chechikepe chechiedzasystem inenge 21 trillion lumens, kureva kuti, nhamba ye1000W goridhe halide mwenje inenge 200-300. Ramba uchiwedzera huwandu hwerambi rehove, kuvandudza kupenya kwechikepe chemwenje, kuvandudza mhedzisiro yekuunganidza hove hakubatsiri zvakanyanya !! (kunze kwekunge kuwedzera simba uye nhamba yezviedza panguva imwe chete, simudza urefu hwezviedza zvakarembera, uye shandura Angle yezviedza zvakarembera).
