Ugqibele nini ukuthenga ithotshi entsha? Ukuba awukhumbuli, kusenokuba lixesha lokuba uqale ukuthenga izinto ezahlukeneyo.
Kwiminyaka engamashumi amahlanu eyadlulayo, itotshi ephezulu kakhulu yayenziwe nge-aluminium, idla ngokuba mnyama, yayinentloko yendibano yesibane eyayijika ukuze igxile kwi-beam kwaye yayisebenzisa iibhetri ezimbini ukuya kwezintandathu, nokuba yi-C okanye i-D-cell. Yayisisibane esinzima kwaye yayisebenza ngokulinganayo njengenduku, nto leyo eyabangela ukuba amagosa amaninzi abe nengxaki njengoko amaxesha kunye nobuchwepheshe butshintsha. Yiya phambili kwixesha langoku kwaye itotshi yegosa eliqhelekileyo ingaphantsi kwee-intshi ezisibhozo ubude, inokwenzeka ukuba yenziwe nge-polymer njenge-aluminium, inendibano yesibane se-LED kunye nemisebenzi/amanqanaba okukhanya amaninzi afumanekayo. Omnye umahluko? Itotshi kwiminyaka engama-50 eyadlulayo yayixabisa malunga ne-$25, isixa esikhulu. Kwelinye icala, itotshi zanamhlanje zinokubiza i-$200 kwaye zithathwa njengesivumelwano esihle. Ukuba uza kuhlawula olo hlobo lwemali, zeziphi iimpawu zoyilo ekufuneka uzikhangele?
Njengomthetho, masivume ukuba zonke iitotshi zomsebenzi kufuneka zibe ncinci kwaye zikhaphukhaphu ngokwaneleyo ukuze zithwalwe lula. "Ezimbini ngomnye omnye akukho namnye," sisichazi-magama sokhuseleko lokusebenza ekufuneka silwamkele. Njengoko malunga nama-80 ekhulwini okudubulana kwamapolisa kwenzeka kwiimeko eziphantsi okanye ezingenakukhanya, ukuba netotshi ngamaxesha onke xa usemsebenzini kuyimfuneko. Kutheni ngexesha lomsebenzi wasemini? Kuba awuyazi ukuba imeko iya kukusa nini kwigumbi elingaphantsi elimnyama lendlu, isakhiwo sezorhwebo esingenanto apho umbane ucinyiwe khona okanye ezinye iimeko ezifanayo. Kufuneka ube netotshi nawe kwaye kufuneka ube nenkxaso. Isibane esifakwe kwisixhobo kwipistol yakho akufuneki sithathwe njengenye yeetotshi ezimbini. Ngaphandle kokuba amandla abulalayo afanelekile, akufanele ukhangele ngesibane sakho esifakwe kwisixhobo.
Ngokubanzi, iitotshi zanamhlanje eziphathwa ngesandla ezisebenzisa ubuchule azifanele zibe ngaphezu kwee-intshi ezisibhozo ubude obuphezulu. Zinde ngaphezu koko kwaye ziqala ukungakhululeki kwibhanti yakho yesibhamu. Ii-intshi ezine ukuya kwezintandathu bubude obungcono kwaye ngenxa yetekhnoloji yebhetri yanamhlanje, loo bude banele ukuba nomthombo wamandla owaneleyo. Kwakhona, ngenxa yophuhliso lwetekhnoloji yebhetri, loo mthombo wamandla unokutshajwa kwakhona ngaphandle koloyiko lokuqhuma okutshajiswa kakhulu, ukufudumeza kakhulu kunye/okanye uphuhliso lwememori olugqibela ngokwenza ibhetri ingasebenzi. Inqanaba lokukhupha ibhetri alibalulekanga ukwazi njengoko kunjalo nangolwalamano phakathi kokusebenza kwebhetri phakathi kweetshaji kunye nesiphumo sokuhlanganiswa kwesibane.
I-XT DF flashlight eyenziwe yi-ASP Inc. inika ukukhanya okunamandla, okungama-600 lumens okuqala, kunye nenqanaba lokukhanya lesibini elinokucwangciswa ngumsebenzisi kwi-15, 60, okanye 150 lumens, okanye i-strobe. I-ASP Inc. Iibhalbhu ze-incandescent ziyinto yexesha elidlulileyo kwii-tactical lightlights. Ziphuka lula kwaye ukukhanya "kungcolile kakhulu." Xa ii-LED assemblies zaqala ukungena kwimarike yokukhanya okusebenzayo kwiminyaka embalwa eyadlulayo, ii-65 lumens zazithathwa njengezikhazimlayo kwaye linqanaba elincinci lokukhanya okusebenzayo kwisibane esisebenzayo. Ngenxa yophuhliso lwetekhnoloji, ii-LED assemblies ezityhala ii-500+ lumens ziyafumaneka kwaye ngoku kuvunyelwene ngokubanzi kukuba akukho nto injengokukhanya okuninzi. Ibhalansi ekhoyo ikhona phakathi kokukhanya okusebenzayo kunye nobomi bebhetri. Nangona sonke singathanda ukuba nesibane esingama-500 lumens esihlala iiyure ezilishumi elinesibini zokusebenza, oko akunakwenzeka. Kusenokufuneka samkele isibane esingama-200 lumen esisebenza iiyure ezilishumi elinesibini. Ngokwenyani, asisayi kuze sifune ukuba ithotshi yethu ivuthe xa sisebenza ixesha elizeleyo, ingayeki, ngoko ke kuthekani ngesibane se-lumen esingama-300 ukuya kuma-350 esinebhetri esinokuhlala iiyure ezine sisebenza ixesha elide? Loo ntsebenziswano yokukhanya/umbane, ukuba ukusetyenziswa kokukhanya kulawulwa ngokufanelekileyo, kufuneka ihlale ixesha elide.
Inzuzo eyongezelelekileyo yeendibano zezibane ze-LED kukuba ulawulo lokuhambisa umbane ludla ngokuba yi-digital circuitry evumela ukusebenza okongeziweyo ngaphandle kokuvula nokucima. I-circuitry kuqala ilawula ukuhamba kombane kwi-LED assembly ukuyithintela ekutshiseni kakhulu kwaye ilawula ukuhamba kombane ukuze inike inqanaba lokukhanya elithembekileyo nelilinganayo. Ngaphaya koko, ukuba ne-digital circuitry kunokwenza imisebenzi efana nale:
Kwiminyaka engamashumi amabini edlulileyo, ukusukela oko i-Surefire Institute yokuqala kunye ne-BLACKHAWK Gladius flashlight elandelayo zibonise amandla okukhanya kwe-strobing njengesixhobo sokuguqula indlela yokuziphatha, izibane ze-strobe bezisoloko zidumile. Kuqhelekile ngoku ukuba i-flashlight ibe neqhosha lokusebenza eliza kuhambisa ukukhanya ukusuka kumandla aphezulu ukuya kumandla aphantsi ukuya kwi-strobing, ngamanye amaxesha litshintsha ulandelelwano oluxhomekeke kwimfuno yemarike ebonwayo. Umsebenzi we-strobe unokuba sisixhobo esinamandla esinamacebiso amabini. Okokuqala, i-strobe kufuneka ibe yi-frequency efanelekileyo kwaye okwesibini, umqhubi kufuneka aqeqeshwe ekusebenziseni kwayo. Xa ingasetyenziswa ngendlela engafanelekanga, ukukhanya kwe-strobe kunokuba nefuthe elikhulu kumsebenzisi njengoko kunjalo kwithagethi.
Ngokucacileyo, ubunzima buhlala buyinto exhalabisayo xa sisongeza into kwibhanti yethu yezibhamu kwaye xa sijonga isidingo sezibane ezimbini, inkxalabo yobunzima iyaphindaphindeka. Isibane esiphathwa ngesandla esilungileyo kwihlabathi lanamhlanje kufuneka sibe nobunzima obuzii-ounces ezimbalwa kuphela; ngaphantsi kwesiqingatha seponti ngokuqinisekileyo. Nokuba sisibane esenziwe nge-aluminium esincinci okanye esenziwe nge-polymer, ukuba nobunzima obungaphantsi kwee-ounces ezine akusoloko kuyingxaki enkulu xa kujongwa imida yobukhulu.
Ngenxa yokuba inkqubo yamandla enokutshajwa kwakhona iyimfuneko, inkqubo yokubeka i-docking iyathandabuzeka. Kulula kakhulu ukungasusi iibhetri ukuze uzitshajwe kwakhona, ngoko ke ukuba i-flashlight ingatshajwa kwakhona ngaphandle kokwenza njalo, luyilo olunqwenelekayo ngakumbi. Ukuba isibane asitshajwa kwakhona kufuneka kubekho iibhetri ezongezelelweyo kwigosa ngexesha lotshintsho oluthile. Iibhetri zeLithium zintle kakhulu ngokuba nexesha elide kodwa phantsi kweemeko ezithile kunokuba nzima ukuzifumana, kwaye xa uzifumene, zinokubiza kakhulu. Itekhnoloji yanamhlanje ye-LED inika amandla ukusetyenziswa kweebhetri eziqhelekileyo ze-AA njengombane ngomda wokuba azizukuhlala ixesha elide njengezalamane zazo ze-lithium, kodwa zibiza kancinci kakhulu kwaye zifumaneka ngokubanzi.
Ngaphambili sikhankanye ngesekethe yedijithali enika amandla iindlela zokukhanya ezinemisebenzi emininzi kwaye enye iteknoloji ekhulayo yenza ukuba olo phawu lulula/lolawulo lube namandla ngakumbi: uqhagamshelo lwamazinyo aluhlaza okwesibhakabhaka. Ezinye izibane "ezicwangcisiweyo" zifuna ukuba ufunde incwadi yemiyalelo kwaye ufumane ulandelelwano olufanelekileyo lokucinezela amaqhosha ukuze ucwangcise ukukhanya kwakho ukuze ufumane amandla okuqala, imida ephezulu/ephantsi nokunye. Ngenxa ye-blue tooth tech kunye nee-apps zefowuni ezikrelekrele, ngoku kukho izibane ezithengiswayo ezinokucwangciswa kwifowuni yakho ekrelekrele. Ezi apps azikuvumeli nje kuphela ukuba ulawule ukucwangcisa ukukhanya kwakho kodwa zikuvumela ukuba ujonge amanqanaba ebhetri.
Kakade ke, njengoko bekutshiwo ekuqaleni, yonke le mveliso intsha yokukhanya, amandla kunye nokulula kokwenza iinkqubo kuza nexabiso. Ukukhanya okusemgangathweni, ukusebenza okuphezulu, nokucwangciswayo kunokubiza malunga ne-$200. Umbuzo oza engqondweni ke ngulo - Ukuba uza kuba namava naziphi na iimeko eziphantsi okanye ukungabikho kokukhanya ngexesha lomsebenzi wakho, kwaye ukuba kukho amathuba angama-80 ekhulwini okuba naluphi na uhlaselo lwamandla okubulala onalo luya kuba kwimeko enjalo, ngaba uzimisele ukutyala imali eyi-$200 njengepolisi yomshuwalense wobomi enokubakho?
Ithotshi ye-XT DF eyenziwe yi-ASP Inc. inika ukukhanya okunamandla, okumalunga nama-600 lumens okukhanya okuphambili, kunye nenqanaba lokukhanya lesibini elinokucwangciswa ngumsebenzisi kwi-15, 60, okanye 150 lumens, okanye i-strobe.
