Ugcine nini ukuthenga ithoshi elisha? Uma ungakhumbuli, kungase kube yisikhathi sokuqala ukuthenga endaweni yonke.
Eminyakeni engu-50 edlule, ithoshi eliphezulu lalenziwe nge-aluminium, ngokuvamile elimnyama, lalinekhanda lokuhlanganisa isibani elalijika ligxilise uhlaka futhi lisebenzisa amabhethri amabili kuya kwayisithupha, kungaba C noma D-cell. Bekuwukukhanya okusindayo futhi kusebenza ngendlela efanayo njengenduku, okuvele kwathola izikhulu eziningi enkingeni njengoba izikhathi nobuchwepheshe buthuthuka. Gxumela phambili manje futhi ithoshi lesikhulu elimaphakathi lingaphansi kwamayintshi ayisishiyagalombili ubude, kungenzeka ukuthi lakhiwe nge-polymer njengoba liyi-aluminium, linokuhlanganiswa kwesibani se-LED kanye nemisebenzi/amaleveli amaningi okukhanya atholakalayo. Omunye umehluko? Ithoshi eminyakeni engu-50 edlule lalibiza cishe u-$25, inani elibalulekile. Ngakolunye uhlangothi, amathoshi anamuhla angabiza u-$200 futhi athathwa njengento enhle. Uma uzokhokha lolo hlobo lwemali, yiziphi izici zokuklama okufanele uzibheke?
Njengomthetho, masikwamukele ukuthi wonke amathoshi omsebenzi kufanele aminyene futhi alula ukuze athwale kalula. “Ababili munye futhi oyedwa akekho,” kuwumgomo wokuphepha ekusebenzeni okudingeka siyamukele. Cishe amaphesenti angu-80 wokudubula kwabantu bomthetho okwenzeka ezimweni eziphansi noma ezingenakukhanya, ukuba nethoshi nawe ngaso sonke isikhathi lapho usemsebenzini kuyisibopho. Kungani ngesikhathi sosuku? Ngoba ngeke wazi ukuthi izimo zizokufaka nini ngaphansi kwendlu emnyama, isakhiwo sezentengiselwano esingenamuntu lapho amandla acishiwe noma ezinye izimo ezifanayo. Kufanele ube nethoshi nawe futhi kufanele ube nesipele. Isibani esifakwe ngezikhali kusibhamu sakho akufanele sithathwe njengesinye sezibani ezimbili. Ngaphandle uma amandla abulalayo anesizathu, akufanele useshe ngesibani sakho esifakwe isikhali.
Ngokuvamile, amathoshi aphathwayo ahlakaniphile anamuhla akufanele alinganise amayintshi ayisishiyagalombili njengobude obukhulu. Isikhathi eside kunalokho futhi baqala ukungakhululeki ebhandeni lakho lesibhamu. Amayintshi amane ukuya kwayisithupha ubude obungcono futhi sibonga ubuchwepheshe banamuhla bebhethri, lobo ubude obanele ukuze ube nomthombo wamandla owanele. Futhi, ngenxa yokuthuthukiswa kobuchwepheshe bebhethri, lowo mthombo wamandla ungashajwa ngaphandle kokwesaba ukuqhuma kokushajwa kakhulu, ukushisisa ngokweqile kanye/noma ukuthuthukiswa kwenkumbulo okugcina kwenze ibhethri lingabi namsebenzi. Izinga lokukhipha ibhethri alibalulekile ukwazi njengobudlelwano phakathi kokusebenza kwebhethri phakathi kokushajwa nokuphumayo kokuhlanganisa isibani.
Ithoshi le-XT DF le-ASP Inc. linikeza ukukhanya okukhulu, okungu-600 kokukhanya okuyisisekelo, okunezinga lesibili lokukhanya elingahlelwa umsebenzisi ku-15, 60, noma ku-150 lumens, noma i-strobe.ASP Inc.Izibani ze-Incandescent aziyinto yesikhathi esedlule. amathoshi ahlakaniphile. Ziphuka kalula futhi ukukhanya “kungcole” kakhulu. Lapho ama-LED assemblies eqala ukufika emakethe yokukhanya yamaqhinga emashumini ambalwa eminyaka emuva, ama-lumens angama-65 athathwa njengokugqama kanye nezinga eliphansi lokukhipha ukukhanya kokukhanya kwamaqhinga. Ngenxa yokuvela kobuchwepheshe, ama-LED ahlanganisa ama-lumens angu-500+ ayatholakala futhi ukuvumelana okujwayelekile manje ukuthi ayikho into efana nokukhanya okuningi. Ibhalansi ezotholakala ikhona phakathi kokukhipha ukukhanya nempilo yebhethri. Nakuba sonke singathanda ukuba nesibani esingu-500-lumen esihlala amahora ayishumi nambili okusebenza, lokho akulona iqiniso. Kungase kudingeke ukuthi sivumelane nesibani esingu-200-lumen esisebenza amahora ayishumi nambili. Uma sikhuluma iqiniso, ngeke sidinge ithoshi lethu likhanyise ukuze sishintshe ngokuphelele, singami, ngakho-ke kuthiwani ngokukhanya okungu-300- kuya ku-350-lumen ngebhethri elingahlala amahora amane okusetshenziswa kancane? Lobo budlelwano bokukhanya/amandla, uma ukusetshenziswa kokukhanya kulawulwa kahle, kufanele kuqhubeke kalula amashifu ambalwa.
Inzuzo eyengeziwe yemihlangano yesibani se-LED ukuthi izilawuli zokulethwa kwamandla ngokuvamile ziyi-digital circuitry evumela ukusebenza okwengeziwe ngaphandle kokuvala nokuvala. I-circuitry ilawula kuqala ukugeleza kwamandla ukuya kumhlangano we-LED ukuze ivinjwe ekushiseni ngokweqile futhi ilawule ukugeleza kwamandla ukuze inikeze izinga elithembeke nakakhulu lokukhanya. Ngaphandle kwalokho, ukuba naleyo mjikelezo wedijithali kunganika amandla imisebenzi efana nale:
Cishe eminyakeni engamashumi amabili edlule, kusukela i-Surefire Institute yasekuqaleni kanye ne-BLACKHAWK Gladius flashlight ibonise amandla okukhanya okuzulazulayo njengethuluzi lokuguqula ukuziphatha, izibani ze-strobe bezilokhu zihamba phambili. Sekuyinsakavukela umchilo wesidwaba manje ukuthi ithoshi libe nenkinobho yokusebenza ezohambisa ukukhanya ngamandla aphezulu kuye emandleni aphansi ukuya ku-strobing, ngezikhathi ezithile iguqule ukuhleleka okuncike esidingweni esicatshangwayo semakethe. Umsebenzi we-strobe ungaba ithuluzi elinamandla elinama-caveats amabili. Okokuqala, i-strobe kufanele ibe imvamisa efanele futhi okwesibili, opharetha kufanele aqeqeshwe ekusetshenzisweni kwayo. Ngokusebenzisa okungalungile, ukukhanya kwe-strobe kungaba nomthelela omningi kumsebenzisi njengoba kwenza kumpokophelo.
Ngokusobala, isisindo sihlala sikhathaza lapho sengeza okuthile ebhandeni lethu lesibhamu futhi lapho sibheka isidingo samathoshi amabili ukukhathazeka kwesisindo kuphinda kabili. Ukukhanya okuhle okuphathwa ngesandla kweqhinga ezweni lanamuhla kufanele kube nesisindo esingamaounces ambalwa kuphela; ngaphansi kwesigamu sephawundi ngokuqinisekile. Kungakhathaliseki ukuthi ukukhanya kwe-aluminium enezindonga ezincane ezinodonga oluncane noma okunye kokwakhiwa kwe-polymer, ukuba nesisindo esingaphansi kwama-ounces amane ngokuvamile akuyona inselele enkulu uma kubhekwa imikhawulo yosayizi.
Uma kubhekwa ukufiseleka kwesistimu yamandla aphinde ashajwe, isistimu yokudokha iyangabazeka. Kungcono kakhulu ukuthi ungawasusi amabhethri ukuze uwashaje, ngakho-ke uma ithoshi lingashajwa ngaphandle kokuthi lenze kanjalo, liwumklamo ofiseleka kakhulu. Uma isibani singashajwa futhi amabhethri engeziwe kufanele atholakalele isikhulu ngesikhathi sanoma yisiphi isikhathi sokushintsha. Amabhethri e-lithium ayamangalisa ngokuba nempilo yeshelufu ende kodwa ngaphansi kwezimo ezithile kungaba nzima ukuwathola, futhi uma uwathola, angabiza. Ubuchwepheshe banamuhla be-LED bunika amandla ukusetshenziswa kwamabhethri e-AA avamile njengomthombo wamandla anomkhawulo wokuthi angeke ahlale isikhathi eside njengabazala bawo be-lithium, kodwa abiza kancane kakhulu futhi atholakala kabanzi.
Phambilini sike sasho ukujikeleza kwedijithali okunika amandla izinketho zokukhanya zemisebenzi eminingi futhi obunye ubuchwepheshe obukhulayo benza leso sici esingaba lula / sokulawula siqine nakakhulu: ukuxhumana kwezinyo eliluhlaza okwesibhakabhaka. Ezinye izibani "ezihlelekayo" zidinga ukuthi ufunde imanuwali futhi uthole ukulandelana okufanele kokucindezela inkinobho ukuze uhlele ukukhanya kwakho ukuze uthole amandla okuqala, imikhawulo ephezulu/ephansi nokunye. Ngenxa yezinhlelo zokusebenza ze-blue tooth tech kanye ne-smart phone, manje sekunezibani emakethe ezingahlelwa ngocingo lwakho oluhlakaniphile. Izinhlelo zokusebenza ezinjalo azikuvumeli kuphela ukuthi ulawule ukuhlela ukukhanya kwakho kodwa zikuvumela ukuthi uhlole namaleveli ebhethri.
Yiqiniso, njengoba kushiwo ekuqaleni, konke lokhu okukhipha ukukhanya okusha, amandla nokuhleleka kalula kuza nenani. Ikhwalithi, ukusebenza okuphezulu, ukukhanya kwamaqhinga okuhlelekayo kungabiza kalula cishe u-$200. Umbuzo ofika emqondweni yilo-ke yilo – Uma uzohlangabezana nanoma yiziphi izimo eziphansi noma ezingenakukhanya lapho wenza umsebenzi wakho, futhi uma kunamathuba angamaphesenti angama-80 okuthi noma yimaphi amandla abulalayo ohlangana nawo ayoba kuleyo ndawo. , ingabe uzimisele ukutshala imali engu-$200 njengomshwalense ongase ube khona wokuphila?
Ithoshi le-XT DF le-ASP Inc. linikezela ngokukhanya okukhulu, okungu-600 kokukhanya okuyisisekelo, okunezinga lesibili lokukhanya elingahlelwa umsebenzisi ku-15, 60, noma 150 lumens, noma i-strobe.
