Rakibaadda qalabka nalalka beeraha digaagga!

Waxaa jira farqi u dhexeeya nalalka iftiinka iyo nalalka iftiinka leh iyo saameyntooda rakibaadda.

Guud ahaan, xoogga iftiinka ee ku habboon gudahabeeraha digaaggawaa 5~10 lux (waxaa loola jeedaa: iftiinka la arki karo ee la helo halkii unug, tamarta shucaaca ee guud ee ka soo baxda halkii unug ee dusha sare ee shayga oo ay indhaha iyo indhahu arki karaan). Haddii la rakibo laambad iftiin leh oo aan lahayn dabool 15W ah, waa in lagu rakibaa dherer toosan ama masaafo toosan oo ah 0.7~1.1m jirka digaagga; haddii ay tahay 25W, 0.9~1.5m; 40W, 1.4~1.6m; 60 Watts, 1.6~2.3 mitir; 100 watts, 2.1~2.9 mitir. Masaafada u dhaxaysa nalalka waa inay ahaataa 1.5 jeer masaafada u dhaxaysa nalalka iyo digaagga, masaafada u dhaxaysa nalalka iyo derbigana waa inay ahaataa 1/2 masaafada u dhaxaysa nalalka. Meelaha lagu rakibayo laambad kasta waa inay ahaataa mid isku mid ah oo si siman loo qaybiyo.

 Haddii uu yahay laambad dhalaalaysa, marka masaafada u dhaxaysa laambadda iyo digaaggu ay la mid tahay laambadda dhalaalaysa ee awoodda isku mid ah leh, xoogga iftiinku wuxuu 4 ilaa 5 jeer ka weyn yahay kan laambadda dhalaalaysa. Sidaa darteed, si xoogga iftiinku u noqdo mid isku mid ah, waxaa lagama maarmaan ah in la rakibo laambad cad oo awood yar leh.

Immisa nalalka iftiinka ah ayaa lagu rakibay beeraha digaagga?

Tirada nalalka lagu rakibayo guriga digaagga waxaa lagu go'aamin karaa iyadoo loo eegayo masaafada kor ku xusan ee u dhaxaysa nalalka iyo masaafada u dhaxaysa nalalka iyo derbiga, ama tirada nalalka loo baahan yahay waxaa lagu xisaabin karaa iyadoo loo eegayo aagga waxtarka leh ee guriga digaagga iyo awoodda hal nal, ka dibna la habeeyo oo la rakibo.

 Haddii la rakibo laambadaha nalalka, guud ahaan waa fidsanbeeraha digaaggawaxay u baahan tahay qiyaastii 2.7 watts mitirkiiba laba jibbaaran; guriga digaagga ee qafis badan leh guud ahaan wuxuu u baahan yahay 3.3 ilaa 3.5 watts mitirkiiba laba jibbaaran sababtoo ah saameynta qafisyada digaagga, meelaha qafiska lagu xidho, weelasha cuntada, haamaha biyaha, iwm.

Wadarta watt ee looga baahan yahay guriga oo dhan oo loo qaybiyo watt-ka hal nal waa wadarta tirada nalalka la rakibayo. Waxtarka iftiinka ee nalalka fluorescent-ka guud ahaan waa 5 jeer ka badan nalalka incandescent-ka. Awoodda nalalka fluorescent-ka ee la rakibayo mitirkiiba labajibbaaran waa 0.5 watts guryaha digaagga fidsan, iyo 0.6 ilaa 0.7 watts halkii mitir labajibbaaran guryaha digaagga ee qafisyo badan leh.

 Qafis lakab badan lehbeeraha digaagga, booska rakibaadda laambadda waa inuu ahaadaa mid ka sarreeya qafiska digaagga ama bartamaha safka labaad ee qafisyada digaagga, laakiin masaafada u dhaxaysa digaagga waa inay awood u yeelataa inay hubiso in xoogga iftiinka ee lakabka sare ama lakabka dhexe uu yahay 10 lux., lakabka hoose wuxuu gaari karaa 5 lux, si lakab kasta uu u helo xoogga iftiinka ku habboon. Si loo badbaadiyo korontada loona ilaaliyo xoogga iftiinka ku habboon, waxaa ugu wanaagsan in la dejiyo hadhka laambadda, oo la ilaaliyo nalka, tuubada laambadda iyo hadhka laambadda inay noqdaan kuwo dhalaalaya oo nadiif ah. Qalabka nalalka waa in la hagaajiyaa si aan loo carqaladeyn xayawaanka iyadoo dib iyo dib loo ruxayo marka dabayshu dhacdo.
