The Evolution le Bohlokoa ba Mabone a Hlooho ho Polokeho ea Likoloi

Ho tloha ha ho qaptjoa koloi,mabone a peleli fetohile ho tloha mokhoeng o bonolo oa ho khantša tsela bosiu ho ea ho karolo e rarahaneng e bapalang karolo ea bohlokoa ho polokeho ea likoloi le moralo. E le e ’ngoe ea litsamaiso tsa bohlokoa tsa ho bonesa koloing, mabone a ka pele ha a etse hore bakhanni ba bonahale feela empa hape a etsa hore likoloi li hlokomelehe haholoanyane ho batho ba tsamaeang ka maoto, ba libaesekele le bakhanni ba bang ba likoloi—haholo-holo maemong a tlaase a lebone, boemo ba leholimo bo seng botle, kapa nakong ea mafube le ka shoalane.

Matsatsi a pele a mabone a likoloi a ne a tšoauoa ka bonolo le mefokolo. Qetellong ea lekholo la bo19 la lilemo, likoloi tsa pele li ne li itšetlehile ka mabone a oli kapa mabone a khase, a tšoanang le a likoloi tse huloang ke lipere. Mabone ana a ne a hlahisa khanya e lerootho, e panyang e neng e etsa hore motho a se ke a bonahala haholo, e leng se neng se etsa hore ho khanna bosiu e be mosebetsi o kotsi. Mathoasong a lekholo la bo20 la lilemo, mabone a pele a motlakase a ile a qala ho nkela mabone a pele a ho tuka. Mabone a pele a motlakase, a hlahisitsoeng ka 1912, e ne e le li-bulbs tsa incandescent tse tsamaisoang ke betri ea koloi, tse fanang ka mohloli o khanyang le o tsitsitseng haholoanyane. Leha ho le joalo, ba ne ba ntse ba e-na le mathata: ba ne ba sebelisa matla a maholo, ba hlahisa mocheso, 'me khanya ea bona e ile ea fokotseha ha nako e ntse e ea.

Ho theosa le lilemo tse mashome, tsoelo-pele ea theknoloji e ile ea fetola moralo le tšebetso ea mabone a pele. Bohareng ba lekholo la bo20 la lilemo ho ile ha hlahisoa mabone a sealed-beam a neng a kopanya tleloubu, sebonela-hōle le lense hore e be yuniti e le 'ngoe. Moralo ona o ile oa ntlafatsa ho tšoarella le ho fokotsa litlhoko tsa tlhokomelo, kaha kopano eohle e ile ea nkeloa sebaka ha tleloubu e cha. Lilemong tsa bo-1980, ho ile ha hlaha mabone a lihlooho a kopantsoeng, a lumellang hore ho be le setaele se feto-fetohang le kabo e ntle ea khanya. Mabone ana a lihlooho a arotse tleloubu ho sebonela-hōle le lense, e leng se nolofalletsang baetsi ba likoloi ho etsa meralo e mebe, e matla haholoanyane ha ba ntse ba ntlafatsa khanya.

Kajeno, likoloi tsa sejoale-joale li na le mefuta e mengata ea theknoloji ea mabone a holimo, e 'ngoe le e' ngoe e fana ka melemo e ikhethang. Mabone a Halogen, a ileng a ata ka bo-1970, a sebelisa lesela la tungsten le kentsoeng ka tleloubu e tletseng khase ea halogen. Li theko e tlaase, ho bonolo ho li nkela sebaka, 'me li fana ka leseli le futhumetseng le le mosehla le tloaelehileng ho bakhanni ba bangata. Leha ho le joalo, ha li sebelise matla a mangata 'me li phela nako e khutšoanyane ha li bapisoa le theknoloji e ncha.

Mabone a Xenon HID (High-Intensity Discharge) a hlahisitsoeng ka bo-1990, a emela ho tlolela pele haholo. Mabone ana a hlooho a sebelisa arc ea motlakase pakeng tsa li-electrode tse peli ka tleloubung e tletseng khase ea xenon ho hlahisa leseli le khanyang, le lesoeu le tšoanang hantle le khanya ea motšehare. Mabone a HID a fana ka ponahalo e ntle, sebaka se selelele, le tšebeliso e tlase ea matla ho feta li-halogen bulbs. Li boetse li na le nako e telele ea bophelo, e leng se etsang hore e be khetho e tsebahalang bakeng sa likoloi tsa mabothobotho le tse sebetsang hantle. Leha ho le joalo, litšenyehelo tsa bona tse phahameng le khanya e ka bang teng bakeng sa bakhanni ba tlang ke litšitiso tse hlokomelehang.

Moqapi oa morao-rao oa theknoloji ea lebone la hlooho ke mabone a LED (Light-Emitting Diode). Li-LED ke lisebelisoa tsa semiconductor tse hlahisang leseli ha motlakase o feta ho tsona. Li sebetsa hantle haholo, li sebelisa matla a ka tlase ho 80% ho feta li-halogen bulbs, 'me li na le nako e telele haholo ea bophelo-hangata e tšoarella bophelo bohle ba koloi. Mabone a LED a hlahisa leseli le khanyang, le lesoeu le ntlafatsang phapang le ho fokotsa khatello ea mahlo ho bakhanni. Ho feta moo, boholo ba bona bo kopaneng bo lumella baetsi ba likoloi ho rala libopeho tse rarahaneng tsa lebone la hlooho, e leng se eketsang boipiletso ba koloi. Lisebelisoa tse ngata tsa morao-rao tsa LED li boetse li na le theknoloji e feto-fetohang, e kang adaptive front-lighting systems (AFS), e fetolang tataiso le matla a leseli ho latela lebelo la koloi, seteraeke sa ho tsamaisa le maemo a potolohileng. Ka mohlala, ha e reteleha, AFS e sututsa mabone a pele ho khantša mothipa, e ntlafatsa ponahalo ho pota-pota.

Ka ntle ho tsoelo-pele ea theknoloji, mabone a pele a boetse a tlas'a melao e thata ho netefatsa polokeho le ho fokotsa khanya. Mebuso le mekhatlo ea machaba, e kang Society of Automotive Engineers (SAE) le United Nations Economic Commission for Europe (UNECE), e behile litekanyetso tsa ho khanya ha lebone la hlooho, mokhoa oa ho behoa le ho behoa. Melao ena e ikemiselitse ho leka-lekanya tlhokahalo ea ponahalo e lekaneng bakeng sa mokhanni le tšireletso ea sephethephethe se tlang ho tloha mahlaseli a feteletseng, a ka bakang bofofu ba nakoana le ho eketsa kotsi ea likotsi.

Bohlokoa ba mabone a pele ho polokeho ea likoloi bo ke ke ba feteletsoa. Ho ea ka National Highway Traffic Safety Administration (NHTSA), karolo e kholo ea likotsi tsa likoloi e etsahala nakong ea maemo a tlaase, 'me tšebeliso e nepahetseng ea lebone e ka fokotsa kotsi ea likotsi tsena. Ntle le ho khantša tsela, mabone a pele a boetse a bontša boteng ba koloi ho ba bang, e leng ntho ea bohlokoa maemong a mabe a leholimo a kang pula, moholi kapa lehloa. Likoloi tse ling tsa sejoale-joale li boetse li na le mabone a mots'eare (DRLs), e leng mabone a khanya a tlase a lulang a khantšitse motšehare ho.
