Keli\u0173 \u017eenklai nakt\u012f da\u017enai atrodo tarsi \u0161viest\u0173 patys, nors jokios elektros jiems nereikia. \u0160\u012f efekt\u0105 sukuria retrorefleksija \u2013 fizikinis rei\u0161kinys, kai \u0161viesa atspindima atgal beveik ta pa\u010dia kryptimi, i\u0161 kurios atkeliavo, t. y. \u012f vairuotojo \u017eibintus.<\/p>\n

Dauguma pavir\u0161i\u0173 \u0161vies\u0105 i\u0161sklaido \u012f \u012fvairias puses, tod\u0117l objekt\u0105 matome tik tada, kai dalis \u0161viesos pasiekia akis. Veidrod\u017eiai \u0161vies\u0105 atspindi vienu kryptingu kampu, o retrorefleksiniai pavir\u0161iai j\u0105 nukreipia atgal \u012f \u0161altin\u012f, tod\u0117l \u017eenklas atrodo ry\u0161kus net visi\u0161koje tamsoje.<\/p>\n

Kas slepiasi atspindin\u010dioje pl\u0117vel\u0117je<\/h2>\n

Kelio \u017eenkl\u0173 pavir\u0161ius dengiamas daugiasluoksne atspindin\u010dia pl\u0117vele, sukurta taip, kad efektyviai gr\u0105\u017eint\u0173 automobili\u0173 \u017eibint\u0173 \u0161vies\u0105. Da\u017eniausiai naudojamos dvi technologijos: stiklo mikrokamuoliukai arba mikroprizmi\u0173 strukt\u016bros.<\/p>\n

Stiklo mikrokamuoliuk\u0173 sprendimas paprastai yra pigesnis ir mechani\u0161kai atsparesnis, tod\u0117l gerai tinka ten, kur pavir\u0161ius labiau d\u0117visi. Mikroprizmi\u0173 technologija daugeliu atvej\u0173 yra kelis kartus efektyvesn\u0117, ta\u010diau brangesn\u0117 ir jautresn\u0117 situacijoms, kai \u0161viesa \u012f pavir\u0161i\u0173 krinta itin dideliais kampais.<\/p>\n

Kod\u0117l \u017eenklai taip smarkiai pagerina matomum\u0105<\/h2>\n

Retrorefleksija svarbiausia d\u0117l saugumo: nakt\u012f ir esant prastam orui vairuotojo matomumas smarkiai suma\u017e\u0117ja. Objektai be atspindin\u010di\u0173 element\u0173 da\u017enai pastebimi tik i\u0161 20\u201330 metr\u0173, tod\u0117l reakcijai lieka labai ma\u017eai laiko.<\/p>\n

Tuo metu objektai su atspindin\u010diais pavir\u0161iais gali b\u016bti \u012f\u017ei\u016brimi gerokai anks\u010diau, net 150\u2013200 metr\u0173 atstumu, tod\u0117l vairuotojas turi daugiau laiko \u012fvertinti situacij\u0105 ir laiku suma\u017einti greit\u012f. D\u0117l to retrorefleksin\u0117s med\u017eiagos laikomos vienu efektyviausi\u0173 pasyvaus saugumo sprendim\u0173 keliuose.<\/p>\n

Ilgaam\u017ei\u0161kumas ir ma\u017eesn\u0117s s\u0105naudos<\/h2>\n

Dar vienas privalumas \u2013 energijos nereikia: \u017eenklai i\u0161lieka ai\u0161kiai matomi ne\u012frengiant ap\u0161vietimo ir netiesiant kabeli\u0173. Tai ma\u017eina infrastrukt\u016bros \u012frengimo ir prie\u017ei\u016bros ka\u0161tus, o kartu suma\u017eina ir energijos vartojim\u0105.<\/p>\n

Siekiant, kad atspindintis sluoksnis tarnaut\u0173 ilgiau, mikroprizmin\u0117s pl\u0117vel\u0117s da\u017enai papildomai dengiamos skaidriu apsauginiu sluoksniu, kuris gerina atsparum\u0105 UV spinduliams ir krituliams. D\u0117l to \u017eenklai ilgiau i\u0161laiko ry\u0161kum\u0105 ir re\u010diau reikalauja atnaujinimo.<\/p>\n","protected":false},"excerpt":{"rendered":"
