Xa ukhetha isibane sokuntywila, abantu abaninzi baya kuqhathwa.Phezulu, ilungile ngokwenene, kodwa eneneni, le yimisebenzi esisiseko yeethotshi zokuntywila.Sisixhobo esibalulekileyo sokuntywila, ngoko xa sikhetha isibane sokuntywila, asimele sikhohliswe koku kungaqondi kulandelayo.

Ukuqaqamba

I-Lumen yiyunithi yomzimba echaza ukuguquguquka okukhanyayo, kwaye akukho ngaphandle kokulinganisa ukuqaqamba kwesibane.Indlela ekhanyayo ngayo i-lumen ye-1, inkcazo inzima ngakumbi.Ukuba unomdla, unga Baidu.Ngokwemigaqo ye-layman, iglowubhu yokukhanya ye-40-watt eqhelekileyo inokukhanya okumalunga ne-lumens ezili-10 ngewathi nganye, ngoko inokukhutshwa malunga nama-400 okukhanya okukhanya.

Ke xa kuziwa ekukhetheni isibane sokuntywila, kufuneka sikhethe i-lumens engakanani?Lo ngumbuzo obanzi kakhulu.Ubunzulu, injongo kunye nobuchule bokuntywila zizinto zonke ekukhetheni ukukhanya.Kwaye ukuqaqamba kwahlulahlulwe kukukhanya kwendawo kunye nokukhanya kwe-astigmatism.Ngokuqhelekileyo, izibane zokuntywila kwinqanaba lokungena kunye nezibane ezine-700-1000 lumens zinokuhlangabezana neemfuno ezisisiseko.Ukuba kukuntywila ebusuku, ukuntywila nzulu, ukuntywila emqolombeni, njalo njalo, kufuneka kuqaqambe ngakumbi.I-2000-5000 lumens iya kwenza.Abathandi abaphezulu bezinga eliphezulu abathanda i-5000-10000 lumens, eyona mfuno ephezulu, eqaqambileyo, kwaye inokwanelisa nayiphi na injongo.

Ukongezelela, kwi-lumen efanayo, injongo yokugxila kunye ne-astigmatism ihluke ngokupheleleyo.Ugxininiso lusetyenziswa kakhulu kwizibane ezikude, ngelixa i-astigmatism ikufutshane kuphela, ukukhanya okubanzi, okusetyenziselwa ukufota.

Into evikela amanzi

Ukungangeni kwamanzi sisiqinisekiso sokuqala sezibane zokuntywila.Ngaphandle kokuvalwa kwamanzi, akusiyo imveliso yokuntywila kwaphela.Ukuvalwa kwamanzi kwezibane zokuntywila ikakhulu kubandakanya ukutywinwa komzimba kunye nesakhiwo sokutshintsha.Izibane zokuntywila kwimarike zisebenzisa amakhonkco erabha abicah., Ngexesha elifutshane, umsebenzi ongenamanzi unokufezekiswa, kodwa ngenxa yekhono elibi lokulungiswa kwe-elastic ye-silicone ye-rubber ring, ichaphazeleka ngokulula kubushushu obuphezulu kunye nobushushu obuphantsi, kwaye ine-asidi embi kunye ne-alkali ukumelana nokugqwala.Isetyenziswa amaxesha amaninzi.Ukuba ayitshintshwanga ngexesha, iya kuphulukana nesiphumo sayo sokutywinwa Iza kubangela ukuphuma kwamanzi.

Tshintsha

Izibane ezininzi eTaobao ezithi ziyakwazi ukusetyenziselwa ukuntywila zihlala zibonisa into ebizwa ngokuba yi "magnetic control switch", eyona ndawo ipholileyo yokuthengisa "abadlali" abadlala ngeethotshi.Iswitshi yemagnetron, njengoko negama libonisa, kukusebenzisa umazibuthe ukutshintsha ubukhulu bangoku ngemagnethi, evulekile okanye evale, kodwa umazibuthe unozinzo olukhulu kakhulu, umazibuthe ngokwawo uya kukhukuliseka ngamanzi olwandle, kwaye umazibuthe uya kukhukuliseka. kancinci kancinci ngokuhamba kwexesha., uvakalelo lokutshintsha luya kuncitshiswa.Ngelo xesha, ubuthathaka obubi kakhulu bokutshintsha kokulawula umbane kukuba kulula ukuqokelela ityuwa okanye isanti emanzini olwandle, okwenza ukuba utshintsho lungakwazi ukuhamba, okubangelwa ukungaphumeleli kokutshintsha.Enye ingongoma ekufuneka uyiqaphele kukuba umhlaba ngokwawo nguMazibuthe omkhulu uya kuvelisa intsimi yamagnetic, kwaye intsimi ye-geomagnetic nayo iya kuba nefuthe elingakumbi okanye elingaphantsi kwi-switch yemagnetron!Ngokukodwa kwimeko yokufota kunye nokufota, impembelelo inkulu kakhulu.

Iitotshi zangaphandle zidla ngokusebenzisa iiswitshi zomatshini wohlobo lwethimble.Iingenelo zolu tshintsho zicace kakhulu, umsebenzi ophambili ukhuselekile, ubuthathaka, uzinzile, kwaye unolawulo oluqinileyo.Kwimeko yoxinzelelo oluphezulu kumanzi anzulu, isenokusebenza ngokuzinzileyo.Ngokukodwa kufanelekile ukufota.Nangona kunjalo, ixabiso lezibane zokuntywila zeempawu zangaphandle liphezulu.

Ubomi bebhetri

Ukuntywila ebusuku, izibane kufuneka zivulwe ngaphambi kokuntywila, kwaye ubomi bebhetri obungaphantsi kweyure enye akwanelanga.Ngoko ke, xa uthenga, nikela ingqalelo kwibhetri kunye nobomi bebhetri yesibane.Isalathisi samandla sesibane sokuntywila sinokuba yindlela elungileyo yokuphepha imeko elusizi yokuphelelwa ngamandla phakathi kokuntywila.Ngokuqhelekileyo, phantsi kwemeko ye-18650 (umthamo wangempela 2800-3000 mAh), ukukhanya malunga ne-900 lumens, kwaye ingasetyenziselwa iiyure ze-2.Kwaye nangokunjalo.

Xa ukhetha itotshi, sukujolisa nje ukuqaqamba, ukuqaqamba kunye nobomi bebhetri zihambelana ngokuphambeneyo.Ukuba kwakhona ibhetri ye-lithium ye-18650, ephawulwe i-1500-2000 lumens, kwaye ingasetyenziselwa iiyure ze-2, ngokuqinisekileyo kukho impazamo.Umntu makabe engalunganga malunga nokukhanya kunye nobomi bebhetri.

Kubantu abangaziqhelanga ngokukhethekileyo iitotshi zokuntywila, ezi ngongoma zingasentla kulula ukuba zibanjwe.Ndiyathemba ukuba eli nqaku linokukunceda uqonde iithotshi zokuntywila (brinyte.cn) ngakumbi, ukuze singakhohliswa xa ukhetha.
