Posankha tochi yosambira, anthu ambiri adzapusitsidwa.Pamwamba, ndizabwino kwambiri, koma kwenikweni, izi ndi ntchito zoyambira zowunikira tochi.Ndi chida chofunikira kwambiri pakuthawira pansi, kotero tikasankha tochi yodumphira, tisapusitsidwe ndi kusamvetsetsanaku.

Kuwala

Lumen ndi gawo lakuthupi lomwe limafotokoza kusinthasintha kowala, ndipo ndi chimodzimodzi kuyeza kuwala kwa tochi.Momwe 1 lumen imawonekera, mawuwo ndi ovuta kwambiri.Ngati mukufuna, mutha ku Baidu.Malinga ndi kunena kwa layman, babu wamba wamba wa 40-watt imakhala ndi kuwala kokwanira pafupifupi ma lumens 10 pa watt iliyonse, kotero imatha kutulutsa pafupifupi ma 400 a kuwala.

Ndiye pankhani yosankha tochi yodumphira pansi, ndi ma lumens angati omwe tiyenera kusankha?Ili ndi funso lalikulu kwambiri.Kuzama, cholinga ndi luso la kuvina ndizinthu zonse posankha kuwala.Ndipo kuwalako kumagawidwanso mu kuyatsa malo ndi astigmatism kuyatsa.Nthawi zambiri, nyali zolowera m'madzi ndi tochi zokhala ndi 700-1000 lumens zitha kukwaniritsa zofunikira.Ngati ndikudumphira usiku, kudumphira mozama, kudumphira m'mapanga, ndi zina zotero, iyenera kuwunikira.2000-5000 lumens adzachita.Okonda kwambiri okonda kwambiri ngati 5000-10000 lumens, yomwe ndi yofunika kwambiri, yowala kwambiri, ndipo imatha kukwaniritsa cholinga chilichonse.

Kuonjezera apo, kwa lumen yomweyi, cholinga cha kuika maganizo ndi astigmatism ndi chosiyana kwambiri.Kuyikirako kumagwiritsidwa ntchito kwambiri pakuwunikira kwakutali, pomwe astigmatism imangokhala yapafupi, kuyatsa kosiyanasiyana, komwe kumagwiritsidwa ntchito kwambiri pojambula.

Chosalowa madzi

Kuletsa madzi ndi chitsimikizo choyamba cha magetsi osambira.Popanda kutsekereza madzi, sizinthu zodumphira m'madzi konse.Kutsekereza madzi kwa magetsi odumphira kumakhudzanso kusindikiza thupi ndikusintha mawonekedwe.Magetsi osambira pamsika amagwiritsa ntchito mphete za mphira wamba za silicone., M'kanthawi kochepa, ntchito yopanda madzi imatha kutheka, koma chifukwa cha mphamvu yosauka bwino yokonza mphete ya mphira ya silicone, imakhudzidwa mosavuta ndi kutentha kwakukulu ndi kotsika, ndipo imakhala ndi asidi osauka ndi kukana dzimbiri za alkali.Amagwiritsidwa ntchito kangapo.Ngati sichidzasinthidwa munthawi yake, imataya kusindikiza kwake Idzayambitsa madzi.

Sinthani

Zowunikira zambiri pa Taobao zomwe zimati zitha kugwiritsidwa ntchito pamadzi nthawi zonse zimawonetsa zomwe zimatchedwa "magnetic control switch", yomwe ndi malo abwino ogulitsa "osewera" omwe amasewera ndi tochi.Kusinthana kwa magnetron, monga momwe dzinalo likusonyezera, ndiko kugwiritsa ntchito maginito kuti asinthe kukula kwa maginito kupyolera mu magnetism, kutsegula kapena kutseka, koma maginito ali ndi kusakhazikika kwakukulu, maginito omwewo adzaphwanyidwa ndi madzi a m'nyanja, ndipo maginito adzachita. pang'onopang'ono kufooka pakapita nthawi., kukhudzidwa kwa kusinthako kudzachepetsedwanso.Pa nthawi yomweyi, kufooka koopsa kwambiri kwa kusintha kwa maginito ndikosavuta kusonkhanitsa mchere kapena mchenga m'madzi a m'nyanja, zomwe zimapangitsa kuti kusinthako kusasunthike, zomwe zimabweretsa kulephera kwa kusintha.Mfundo ina yoti muzindikire ndikuti dziko lapansi lokha ndi maginito okulirapo adzapanga maginito, ndipo gawo la geomagnetic lidzakhalanso ndi chikoka chocheperako pa switch ya magnetron!Makamaka pankhani ya kujambula ndi kujambula, zotsatira zake zimakhala zazikulu kwambiri.

Tochi zakunja nthawi zambiri zimagwiritsa ntchito masiwichi amtundu wa thimble.Ubwino wa switch iyi ndiwodziwikiratu, ntchito yofunika kwambiri ndi yotetezeka, tcheru, yokhazikika, komanso yolunjika mwamphamvu.Pankhani ya kuthamanga kwambiri m'madzi akuya, imatha kugwirabe ntchito mokhazikika.Makamaka oyenera kujambula.Komabe, mtengo wamagetsi osambira amitundu yakunja ndiwokwera.

Moyo wa batri

Pakudumphira usiku, magetsi ayenera kuyatsidwa musanadutse, ndipo moyo wa batri wosakwana ola limodzi siwokwanira.Choncho, pogula, tcherani khutu ku batri ndi moyo wa batri wa tochi.Chizindikiro champhamvu cha tochi yodumphira m'madzi chikhoza kukhala njira yabwino yopewera vuto lakutha mphamvu pakati pakuyenda pansi pamadzi.Nthawi zambiri, pansi pa chikhalidwe cha 18650 (kuthekera kwenikweni 2800-3000 mAh), kuwalako ndi pafupifupi 900 lumens, ndipo ingagwiritsidwe ntchito kwa maola awiri.Ndi zina zotero.

Posankha tochi, musamangoyang'ana kuwala, kuwala ndi moyo wa batri ndizofanana.Ngati ilinso 18650 lithiamu batri, yolembedwa 1500-2000 lumens, ndipo ingagwiritsidwe ntchito kwa maola 2, palidi cholakwika.Wina ayenera kukhala wolakwika pakuwala komanso moyo wa batri.

Kwa anthu omwe sadziwa kwenikweni zowunikira zodumphira pansi, mfundo zomwe zili pamwambazi ndizosavuta kukodwa.Ndikukhulupirira kuti nkhaniyi ingakuthandizeni kumvetsetsa tochi za diving (brinyte.cn) zambiri, kuti tisapusitsidwe posankha.
