Inyigisho ya Porofeseri Xiong: Ese urumuri rwinshi rwo kuroba, niko amafi agira ingaruka nziza? (3)

Birabagiranaitara ryo kuroba, ingaruka nziza zamafi?
Mbere yuko tujya muri ibyo, reka tuganire gato kubyerekeye umucyo no kumurika.
Luminance bivuga ubwinshi bwumubiri wa luminance (reaction) ubukana hejuru yumubiri wumucyo (reflektor). Ijisho ryumuntu ryitegereza inkomoko yumucyo uva mucyerekezo kimwe, kandi igipimo cyimbaraga zumucyo muriki cyerekezo hamwe n’ahantu isoko y’umucyo “wabonywe” nijisho ryumuntu isobanurwa nkumucyo wibintu bitanga isoko yumucyo, ni ukuvuga, ubukana bwa luminous kumurongo uteganijwe. Igice cyumucyo ni Candela kuri metero kare (cd / m2). Umucyo ni imyumvire yumuntu kumva ubukana bwurumuri. Ni ingano ifatika. Iyo muganira ku ngingo y’itara ry’amafi, kubera ko urumuri rugamije ahanini amaso y’amafi, ntekereza ko bidakwiye gukoresha umucyo kugirango dusuzume1500w icyuma cya halide itara ryo kuroba.Ahubwo, dukwiye gukoresha imirasire yumucyo, cyangwa imirasire mugihe gito.
Imirasire yumucyo nubwinshi bwumubiri bugaragaza ubukana bwimirasire yikintu kumasoko yimirasire yubutaka muburyo runaka. Yerekeza ku mbaraga zituruka ku mirasire y’imirasire ku gice cy’ibice hamwe n’ibice bikomeye Inguni inyuze mu ndege ihagaritse ikintu gisanzwe mu gihe cy’ibice, ni ukuvuga ko imirasire y’imishwarara y’imirasire ku gice cyateganijwe hamwe na Angle ikomeye. Igice ni watts / (spheroidium m 2)
Kumurika ubusanzwe bivuga ubukana bwurumuri, bivuga urujya n'uruza rw'urumuri rugaragara rwakiriwe kuri buri gice kandi rukapimirwa muri Lux cyangwa Lx. Iyo luminous flux hejuru yubuso bwa metero kare 1 ni lumen 1, kumurika kwayo ni 1 lux. 1Lux = 1Lm / m2. Ikigaragara ni uko igitekerezo cyo kumurika nacyo gishingiye ku myumvire ifatika y'ijisho ry'umuntu. Mugihe cyo gusuzumaicyuma halide squid itara, kumurika kumurika bigomba gukoreshwa. Imirasire yumucyo, izwi kandi nka irradiance, ni imirasire yumucyo kumwanya wubuso bwagaragaye, muri watts kuri metero kare (W / metero kare). Nyamara, amakuru yubushakashatsi agezweho kuri Phototaxis y amafi ahanini ashingiye kumurika rijyanye nicyerekezo cyabantu. Muri iki kiganiro, amakuru hamwe nibice bijyanye nicyerekezo cyabantu biracyakoreshwa, bigomba guhinduka neza ukurikije uburebure bwumuraba nibindi bintu mukoresha nyabyo.
Muri rusange, benshiwattage ndende Amatara yo kuroba mumazinijoro kumurika bikwiye ntibirenze 20Lux, kumurika birenze 0.01Lux ikurura amafi. Niba 30% by'itara ry'itara rya halogene rimurikirwa ku nyanja, noneho kimwe cya kabiri cyurumuri rushobora kwinjira mumazi urebye Inguni. Umubare rusange wa lumens muri sisitemu yumucyo wubwato ni tiriyoni 21 lumens, bivuze ko umubare wa1000 watt icyuma cya halideni nka 200 kugeza 300. Komeza wongere umubare wamatara yuburobyi, utezimbere urumuri rwubwato bwamatara, kunoza ingaruka zo gukusanya amafi ntabwo bifasha cyane !! (keretse niba imbaraga numubare wamatara byiyongereye icyarimwe, kuzamura uburebure bwamatara amanitse).

Shoals ziteganijwe kuguma he? Niba amatara yaka igihe kirekire bihagije, amafi azaguma nko muri metero 100 kandi muri rusange ntazigera yegera.

Ibisubizo byo kuganira ku ngingo ya kabiri: umubare rusange wa lumens yaamatara yorohejesisitemu igera kuri tiriyoni 21 lumens, ni ukuvuga, umubare wamatara ya zahabu ya 1000W hafi 200-300. Komeza wongere umubare wamatara y amafi, utezimbere ubwiza bwubwato bwamatara, kunoza ingaruka zo gukusanya amafi ntabwo bifasha cyane !! (keretse niba wongeyeho imbaraga numubare wamatara icyarimwe, uzamure uburebure bwamatara amanitse, kandi uhindure Inguni yamatara amanitse).
