Kungani amalambu omgwaqo we-LED angena esikhundleni samalambu omgwaqo endabuko?

Ngokusho kokuhlukaniswa komthombo wokukhanya, amalambu omgwaqo angahlukaniswa ngamalambu omgwaqo aholwa kanye namalambu omgwaqo wendabuko. Kodwa-ke, ngokusetshenziswa okwandayo kwamalambu omgwaqo we-LED, amadolobha amaningi aqala ukusebenzisa amalambu omgwaqo aholwa yi-LED esikhundleni samalambu omgwaqo wendabuko. Manje yini umehluko phakathi kwamalambu omgwaqo aholwa kanye namalambu wendabuko?

Umehluko phakathiAmalambu omgwaqo aholwanamalambu omgwaqo wendabuko:

1. Impilo Yenkonzo: Izibani zethrafikhi ze-LED zinempilo yenkonzo ende, ngokuvamile zifika eminyakeni eyi-10. Uma kucatshangelwa umthelela wezimo zangaphandle ezinzima, isikhathi sokuphila kulindeleke ukuthi sehle iminyaka engu-5-6 ngaphandle kokugcina.

Izibani zendabuko zendabuko ezifana nesibani se-incandescent nesibani se-halogen zinempilo emfushane. Ukushintsha isibani esikhanyayo kungukuhlupheka. Kudinga ukushintshwa izikhathi ezingama-3-4 ngonyaka. Izindleko zokulungisa ziphezulu.

2. Design:

Uma kuqhathaniswa nemithombo yokukhanya yendabuko, amalambu omgwaqo aholwa ama-LED anomehluko osobala ku-Optical System Design, izesekeli zikagesi, izindlela zokunciphisa ukushisa kanye nokwakhiwa kokushisa kanye nokwakheka okuhle. Nga-Amalambu omgwaqo aholwaIngabe ukwakheka kwesibani sephethini esakhiwa amalambu we-LED amaningi, amaphethini ahlukahlukene angakhiwa ngokulungisa ukwakheka kwe-LED. Futhi ingahlanganisa zonke izinhlobo zemibala njengenye futhi zonke izinhlobo zezibani zesiginali njengeyodwa, ukuze isikhala esifanayo somzimba wokukhanya singanikezelwa imininingwane yethrafikhi eyengeziwe futhi silungiselele amasu amaningi omgwaqo. Kungabuye kwakha amasignali wemodi enamandla ngokushintsha imodi ye-LED yezingxenye ezahlukene, ukuze ukukhanya kwesiginali yethrafikhi eqinile iba ngabantu abaningi futhi bacace bha.

Isibani sesiginali yendabuko yendabuko sihlanganiswa kakhulu ngomthombo wokukhanya, umnikazi we-lampiw, embonini kanye nesembozo esibonakalayo. Ngandlela thile, kusekhona ukushiyeka okuthile. Izakhiwo ze-LED ezinjengezibani zethrafikhi ze-LED azikwazi ukushintshwa ukuze zenze amaphethini. Lokhu kunzima ukufeza imithombo yokukhanya yendabuko.

3. Akukho mbukiso wamanga:

I-LED Traffic Signal Ukukhanya Spectrum kuyinto emncane, i-monochromatic, akukho hlungathi, umthombo wokukhanya ungasetshenziswa ngokuyisisekelo. Ngoba akufani nesibani se-incandescent, kufanele ungeze izitsha ezikhanyayo ukwenza konke ukukhanya. Ngaphezu kwalokho, kukhipha ukukhanya kombala futhi akudingi ukuhlunga kwelensi yemibala, okuxazulula inkinga yomphumela wokubonisa wamanga kanye ne-chromatic afrration of lens. Hhayi nje kuphela ukuthi amahlandla amathathu kuya kwane kukhanya ngaphezu kwamalambu omgwaqo we-incandescent, futhi unokubonakala okukhulu.

Izibani zethrafikhi yendabuko zidinga ukusebenzisa izihlungi ukuthola umbala owufunayo, ngakho-ke ukusetshenziswa kokukhanya kuncishiswe kakhulu, ngakho-ke amandla wesiginali aphelele okukhanya kwesiginali kokugcina akuphezulu. Kodwa-ke, amalambu omgwaqo endabuko asebenzisa ama-Chips wombala kanye nezinkomishi ezikhanyayo njengohlelo lwe-Optical ukukhombisa ukukhanya okuphazamisayo kusuka ngaphandle (njengokukhanya kwelanga noma ukukhanya kwelanga okusebenzayo, okungukuthi "ukubonisa okungamanga", okungaholela ezingozini.
