LED hniav teeb lub cev tsis tsim hluav taws xob ultraviolet

LED ib lub raj fais fab 0.03 ~ 0.06 watts, siv DC tsav, ib lub raj tsav hluav taws xob 1.5 ~ 3.5 volts, tam sim no 15 ~ 18 mA, cov lus teb ceev ceev, tuaj yeem ua haujlwm ntawm ntau zaus. Nyob rau hauv cov xwm txheej ntawm tib lub teeb pom kev zoo ntawm LED teeb pom kev zoo, lub zog noj yog ib kaum txhiab ntawm cov qhov muag teeb, thiab ib nrab ntawm cov raj fluorescent. Nws yog kwv yees nyob rau hauv Nyiv hais tias yog LEDs nrog ob zaug lub luminous efficiency yog siv los hloov ib nrab ntawm Japanese qhov muag teev. Incandescent thiab fluorescent teeb. Qhov sib npaug ntawm 6 billion litres roj av tuaj yeem khaws cia txhua xyoo. Nyob rau hauv cov ntaub ntawv ntawm tus choj guardrail teeb, lub teeb fluorescent nrog tib cov nyhuv yog ntau tshaj 40 watts, thaum lub zog ntawm txhua LED tsuas yog 8 watts, thiab nws muaj peev xwm muaj yeeb yuj.

Hnub so LED teeb pom kev zoo ntawm lub koob tsheej kho kom zoo nkauj teeb pom kev zoo siv hluav taws xob hluav taws xob hluav taws xob hluav taws xob los tawm lub teeb, thiab cov filaments muaj qhov tsis zoo xws li kev kub nyhiab, cua sov, thiab lub teeb attenuation. Lub teeb LED yog me me thiab lub teeb nyob rau hauv qhov hnyav, encapsulated nrog epoxy resin, tuaj yeem tiv taus kev siv tshuab ua haujlwm siab thiab kev co, thiab tsis yooj yim rau tawg. Qhov nruab nrab lifespan yog 100,000 teev. Kev pabcuam lub neej ntawm kev ua koob tsheej LED teeb lub cev tuaj yeem ncav cuag 5-10 xyoo, uas tuaj yeem txo tus nqi kho lub teeb thiab zam qhov mob ntawm lub teeb hloov ntau zaus.

Lub cev ntawm lub hnub so LED teeb pom kev zoo tsis tsim cov kab hluav taws xob ultraviolet, yog li yuav tsis muaj yoov tshaj cum nyob ib puag ncig lub teeb pom kev zoo li cov teeb pom kev zoo. Cov teeb niaj hnub yog teeb los ntawm qhov hluav taws xob siab tso tawm los ntawm lub rectifier, thiab tsis tuaj yeem teeb thaum qhov hluav taws xob txo. Lub hnub so kho kom zoo nkauj teeb lub cev tuaj yeem teeb nyob rau hauv ib qho ntawm qhov voltage, thiab qhov ci kuj tuaj yeem hloov kho.

LED chips ntawm hnub so LED hniav teeb yuav inevitably muaj hnub nyoog thaum lub teeb pom kev zoo, thiab ces lub teeb decays. Feem ntau, tom qab siv lub sijhawm, cov teeb yuav twv yuav raug me ntsis tsaus dua li qhov pib, thiab lub teeb qis dua tuaj yeem ua kom lub neej ntev dua. Nyob rau ntawm qhov kub ntawm qhov sib txuas ntau dua, lub teeb tawg ntawm LED yuav maj mam nce ntxiv thaum qhov kub nce. Thaum qhov kub thiab txias ntawm LED tshaj qhov sib txuas qhov kub, lub teeb lwj yuav nce hauv txoj kab ncaj nraim.

High luminous efficiency yuav txo tau cov cua sov tsim, thiab txo cov cua sov tsim yuav txo tau lub teeb lwj, thiab ib tug ntau dua junction kub yuav txo tau qhov yuav tsum tau rau radiators. Xaiv cov chips qib siab yog qhov zoo tshaj plaws kev ua koob tsheej LED hniav lub teeb lub cev. Txawm li cas los xij, lub teeb nrog American CREE chips tsis tuaj yeem yuav ntawm qee yam khoom muaj nqis, vim tias lawv kim dhau, thiab qhov sib txawv ntawm cov chips ntawm tib qhov loj yog li 10-100 zaug, thiab qhov sib txawv ntawm cov khoom tiav yog ntau dua.
