LED qhov teeb pom kev zoo yog cov teeb pom kev zoo uas siv lub teeb ci-emitting diodes (LEDs) ua lawv lub teeb ci tseem ceeb, tsim los rau loj - thaj chaw teeb pom kev zoo hauv qhov chaw xws li txoj kev loj tunnels thiab subways. Featuring high -kev ua tau zoo LED modules thiab precision lens-raws li kev faib tawm lub teeb, cov teeb no muaj lub neej ntev (ntau tshaj 50,000 teev), muaj xim zoo nkauj (70–80), thiab IP65 tiv thaiv kev ntsuas; ntse dimming tshuab tso cai rau lawv hloov mus rau cov teeb pom kev zoo tshwj xeeb ntawm cov ntu sib txawv. Muab piv rau cov teeb pom kev zoo ib txwm muaj, lawv ua tiav kev txuag hluav taws xob txog li 50% thiab tuaj yeem txo cov neeg tsav tsheb qhov teeb meem tsis pom kev los ntawm cov tswv yim teeb pom kev zoo.
Tsav los ntawm kev nce qib hauv LED thev naus laus zis, cov khoom lag luam no tau maj mam hloov cov teeb pom kev zoo ib txwm siv txij li thaum xyoo 2000s. Cov thev naus laus zis xws li modular heat dissipation thiab reflective optical designs tau txhim kho cov khoom lag luam kev ntseeg siab ntxiv txij li xyoo 2010s; Cov piv txwv tseem ceeb suav nrog kev teeb tsa ze li ntawm 14,000 linear LED fixtures nyob rau hauv Shenzhen Outer Ring Expressway tunnels thiab daim ntawv thov ntawm Baima Snow Mountain Qhov hauv Yunnan uas tau ua tiav 63% txhua xyoo kev siv hluav taws xob txo. Cov khoom lag luam tseem ceeb tam sim no muaj nyob rau hauv lub zog ntawm 30W txog 320W, txhawb nqa ntau yam input voltages thiab customizable xim kub, thiab ua raws li thoob ntiaj teb thiab domestic qauv xws li IEC thiab GB. Txawm li cas los xij, kev lag luam tseem ntsib cov teeb meem, suav nrog cov nqi pib siab thiab xav tau kev kho kom zoo ntxiv ntawm cov txheej txheem txheej txheem.
