I-Flashlight I-LED engenakulinganiswa: izinkomba, izintengo

I-flashlight iyidivayisi edingekayo kunoma yimuphi umndeni. Isidingo sokukhanyisa isikhala somnyama singavela ngesikhathi sokuhamba emigwaqweni ebusuku, futhi lapho senza umsebenzi wokulungisa emaceleni okufinyelela kanzima. Kukhona nokuguqulwa okukhethekile okusetshenziselwa abasebenzi basezimayini, izivakashi, abasebenzi bezophuthumayo, njll Emakethe yobuchwepheshe namuhla ungathola i-flashlight ibhethri LED, enezinto eziningi eziphawulekayo ezinhlobonhlobo zendabuko.

Izici Eziyinhloko

Noma yikuphi ukukhanya kwe-flashlight kulinganiselwa ngemingcele emibili esemqoka: ububanzi be-luminescence nokukhanya. Ngokuvamile, lezi zici zihlobene futhi zigeleza, kepha kunezinguqulo ezikhethekile lapho lobu buhlobo obungasebenzi khona. Ngokuqondene nepharamitha yokuqala, izibani ezinamandla ze-LED nge-lens zinganikeza ububanzi cishe ngo-150-200 m. Kodwa ngisho ne-lens ayisize njalo ukugcina ububanzi bokukhanya kokukhanya. Ukuze uqinisekise ubude obude, kubalulekile ukugxila ibhambe njengoba ilula. Ngakho-ke, i-beam izoba "ubude obude", kodwa inesizotha ngobubanzi. Amamodeli asetshenziswe kaningi kakhulu anama-50-120 m. Kuleli cala, ngisho nezilinganiso zamandla okukhanya ngaphandle kwe-lens zinganikeza ububanzi obukhulu endaweni ekhanyayo.

Isimo ngokukhanya, esichazwe ku-lumens (Lm), sinembile. Ingxenye yokuqala ibonisa izinhlobo ze-300-350 lm. Amadivayisi anjalo akwazi ukunikeza ububanzi obungaphezu kwamamitha angu-100, futhi ahluke ezindaweni eziningi zokukhanya. Amadivayisi aphambili anama-LED angama-900-1800 Lm. Lokhu kuvumela, okungenani, ukwandisa indawo yokuqapha, kodwa ngokwebanga, inani lamakhodi asetshenzisiwe lizodlala indima ebalulekile. Isibonelo, i-flashlight ekhanyayo ye-LED enezici ezimbili ezikhanyayo iyakwazi ukuletha ukukhanya ku-150 m ngobukhulu obukhulu, ngokukhanya okungaphezulu kwama-350 lm. Ingabe ukushintshaniswa kokukhanya okuphezulu kulungele i-LED yesibili? Ezimweni lapho kubalulekile ukwandisa ukunikezwa kwamandla, ukucushwa okunjalo ngempela kukonga.

Izici zebhethri

Emakethe kukhona namanje izibani zendabuko kumabhethri angu-2-3, kodwa ngokuphindaphindiwe kuthathwa esikhundleni samamodeli ebhethri. Empeleni, kunezinguqulo ezimbili zamabhethri zalolu hlobo - i-Li-Ion yesimanje kanye ne-Ni-Cd yokuguga. I-voltage evamile kuzo zombili izimo i-4-6 V. Ivolumu, lapho ubude benkampani incike khona, bububanzi buka-1-4 A * h. Kuncike ekusebenzeni, ukukhanya okufanayo nenani lama-LED, ibhethri lingakwazi ukulondoloza amandla kusuka emahoreni amaningana kuya kumahora angu-24 kwimodi evuthayo eqhubekayo. Futhi lapha into ebalulekile ibhethri ngokwalo, ehlome nge-flashlight elayishwayo e-LED ekusebenzeni okuqondile.

Amabhuloki e-Nickel-cadmium abonakala ngokumelana nokushintsha kwezinga lokushisa, ukushayela kwezinga eliphezulu, kodwa ngesikhathi esisodwa, kanye nokuphila okuncane. Amaseli e-lithium-ion amaningi adingekayo, okuyizingqinamba ezihlanganisiwe zingaba nomthamo omkhulu. Kodwa zibiza kakhulu. Ngendlela, akufanele ushiye ngokuphelele imodeli yebhethri, uma kunezinye izici ezifanelekile. Zingahle zithuthukiswe ngokufaka uhlelo lwesistimu yokunikezwa kwamandla - ukuhlinzwa okunjalo kuvame ukuhambisana nezibani zekhanda lobuchwepheshe be-LED. Ukwenza umsebenzi wokuzijabulisa ekhaya kuzoncishiswa kuze kususwe ekamelweni lebhethri nokufakwa komnikazi webhethri. Lezi zinsuku zingathathwa emgqeni wamadivayisi eselula.

Izimpawu zokuzivikela zama-flashlights e-LED

Ngisho noma singakhulumi ngezicelo ezikhethekile, izibani zingavezwa ezicini ezihlukahlukene zethonya langaphandle - kusuka kumswakama ophezulu kuze kube nemithelela engakahleleki. Kodwa okwedlulele kunazo zonke kule ndaba yizibani ze-LED ze-headlamp amabhethri, ezenzelwe ukusebenza ezimayini. Zibonakala ngesigaba sokuvikelwa kwekhasi IP68, okusho ukumelana okukhulu nokulimala ngokomzimba. Kukhona nezinguqulo ezikhethekile zezivakashi. Kulesi simo, ukugcizelela kungenziwa ezindaweni zokumelana kwamanzi. Ukuguqulwa kwalolu hlobo, isibonelo, kungabhapathizwa emanzini kuya ku-1-2 m.

Abakhiqizi

Kuhluka kwesabelomali, ungathola iziphakamiso ezithakazelisayo ezivela kubakhiqizi basekhaya bezinto zokukhanyisa. Ngaphansi kwegama elithi "Bright Beam" nelithi "Svetozar" kukhona izindleko eziphansi, kodwa amamodeli aphezulu kakhulu okusetshenziswa ekhaya. Ngokuqondene nezinguqulo ezikhethekile, ukuguqulwa kokwakhiwa kanye nembonini kuyotholakala emindenini yeCamelion, i-Dewalt ne-Bosch. Okuphawulekayo yizimpawu ze-LED ze-hybrid ezivela ku-Hangliang. Ngokuyinhloko, ukuguqulwa kwe-HL-W110 akuyona kuphela i-flashlight, kodwa i-baton. Lo modeli uboniswa ngomzimba ophakeme kakhulu namandla okukhanya okukhanya. Amadivaysi anokusebenza okuhlangene nawo anikezwa yi-JTC, u-Enkor nabanye.

Kungakanani ukukhanya okukhanyayo kwe-LED?

Amathanga amanani angabizi kakhulu kuma-LED angama-ruble angu-500. Le nguqulo elula yedivaysi yasekhaya ngaphandle kwezinzuzo ezikhethekile zokusebenza. Imakethe yezimpahla inikeza onobuhle obukhulu, etholakalayo ku-1-1.5 izinkulungwane. Ngesikhathi esifanayo, kuncike kakhulu kumenzi okhiqiza ama-flashlights e-LED. I-China kule ndaba iyinkululeko yentando yeningi - isibonelo, izinguqulo eziningi ezivela ku-TrustFire zibiza ama-ruble angu-1000, kodwa ngesikhathi esifanayo zikhombisa amandla afanayo njengamanye amashintshi avela ku-Bosch afanele ama-2 000.

Ungakhetha kanjani i-flashlight efanele?

Ngaphezu kwezici ezichazwe ngenhla, akufanele ukhohlwe mayelana nokusebenza, ukulungisa amandla kanye nemishini eyengeziwe. Ngezidingo zomkhaya, kuzoba namamodeli akwanele anezilungiselelo ezincane. Kodwa inkundla yobuchwepheshe ingadinga ukuthi idivaysi ibe nezinqubo ezimbalwa zokusebenza, izindlela zokulondoloza amandla eziphezulu kanye nezinsizakalo zokubambisana.

Ngakho-ke, i-flashlight LED flashlights nge-lens yokugeleza okunamandla emayini noma ngaphansi kwezimo zamanzi ivame ukufakwa ngezingodo ezikhethekile - isibindi noma izihloko ezifanayo. Ngokuphathelene namathuba okulungiswa, kuye ngokuthi izimo zohlelo lokusebenza, umsebenzisi uzokwazi ukulungisa kahle ibanga le-boram nobubanzi balo ndawo.

Isiphetho

Imakethe yesimanje yamadivayisi e-LED isathuthuka ngokubili ngokuvumelana nokugcwaliswa kwe-optical kanye ne-ergonomic. Inhlanganisela ephumelelayo yemingcele eminingana yezobuchwepheshe neyokusebenza ihlukile nakwezimali zesibhajethi ze-LED. I-China iphinde ibe negalelo ekuphakanyisweni kwemikhiqizo enjalo ekhangayo nangenxa yamanani aphansi. Enye into ukuthi le mfanelo kulesi simo ingaphansi kweYurophu, futhi ngokuvamile imikhiqizo yasekhaya. Ngaphambi kokubhena nokusebenza kwangaphandle, kodwa ukuqina kwamaseli ebhethri nama-LED kushiya okuningi okudingekayo.
