Chiedza cheChiratidzo cheTraffic cheVafambi neVafambi che LED

Marambi e LED evanofamba netsoka chikamu chakakosha chehurongwa hwekutarisira traffic mumaguta, akagadzirirwa kuvandudza kuchengetedzeka kwevanofamba netsoka panzvimbo dzinoyambuka migwagwa nedzinoungana. Marambi aya anoshandisa tekinoroji ye light-emitting diode (LED), iyo inopa mabhenefiti akati wandei pamusoro pemarambi echinyakare e incandescent, anosanganisira kushandisa simba zvakanyanya, kurarama kwenguva refu, uye kuona zviri nani mumamiriro ese ekunze.

Kazhinji, zviratidzo zve LED zvinoratidzwa nevanofamba netsoka zvinoratidza zviratidzo kana magwaro, akadai semunhu anofamba (zvichireva "kufamba") kana ruoko rwakasimudzwa (zvichireva "kusafamba"), kuti zvitungamirire vafambi mukuita sarudzo dzakachengeteka pavanenge vachiyambuka mugwagwa. Mavara akajeka uye akajeka emwenje ye LED anoita kuti chiratidzo chionekwe zvakajeka masikati neusiku, zvichideredza njodzi yetsaona.

Pamusoro pebasa rawo guru rekuratidza vanofamba netsoka zviratidzo, mwenje iyi inogonawo kubatanidzwa nedzimwe nzira dzekutarisira traffic, dzakadai sema countdown timer kana sensors dzinoona kuvapo kwevanofamba netsoka, zvichiwedzera kuvandudza kuchengetedzeka uye kushanda zvakanaka kwenzvimbo dzemaguta. Kazhinji, mwenje ye LED yevanofamba netsoka inoita basa rakakosha mukusimudzira kufamba kwakachengeteka uye kwakarongeka kwevanofamba netsoka munzvimbo dzakabatikana dzemaguta.
