LED teeb rau lub tsev: qhov twg yog qhov tseeb?

Peb lub tsev yog nce pib tshwm khoom-xeev teeb pom kev zoo. LED teeb rau tsev tsim nyob ib ncig ntawm nws ib tug ntau ntawm taug xaiv thiab kev tsis sib haum ntaub ntawv.

Nyob rau hauv ib tes, cov manufacturers hais tias lub neej ntawm tej khoom yog 10-11 xyoo, tab sis ntawm qhov tod tes, muab ib tug guarantee ntawm xwb 3-5 xyoo. Ib tug ntau ntawm sib tham txog tus LED degradation, uas ua rau txo kev khiav hauj lwm lub sij hawm ntawm lub semiconductor ntsiab. Manufacturers faib cov ntaub ntawv uas LED teeb rau tsev muaj ib theem siab ntawm qhov kaj thiab qhov glow, thiab nyob rau lwm cov tes, cov neeg siv nyob rau hauv ib lub suab hais tias, hais tias cov teeb kaj lug txaus. Lub advertisement hais tias cov diodes tsim mos lub teeb thiab flicker li fluorescent teeb, thiab cov neeg hais tias lawv muaj ib tug phem emission spectrum.

Tam sim no hais txog cov ib puag ncig thiab huv si. Muaj yog ib tug ntau ntawm cov ntaub ntawv uas cov LED teeb rau lub tsev, raws li txwv mus rau lub zog-saving, tsis muaj mercury. Raws li, lawv yeej tsis muaj teeb meem rau kev siv thiab yooj yim pov tseg ntawm tsis muaj xyuas cov ib puag ncig. Nyob rau lwm cov tes, manufacturers yog kiag li ntsiag to rau lwm yam teeb meem tshuaj nyob rau hauv lawv cov khoom.

Lwm contradictory cov ntaub ntawv yog tus nqi thiab rov qab los rau peev ntawm tej teeb. Leej twg los yeej muaj pov thawj tus nqi siab ntawm LED teeb rau lub tsev, tab sis lub advertising cog lus tias nyob rau hauv tsib lub xyoos lawv yuav tau them rau nws tus kheej vim yog lub uas tsis muaj zog noj thiab ntev kev pab cuam lub neej. Tw cam hais tias lub teeb muab ib tug faint glow, thiab yog li ntawd lawv yuav tsum tau muab tso rau ntau ntau (ntau), thiab raws li ib tug tshwm sim yuav ua rau kom zog noj. Thiab nyob rau hauv thiaj li yuav ntev lub neej ntawm lub LEDs, nws yog tsim nyog rau nruab ntxiv khoom - voltage regulators, zoo heev ua rau tus nqi ntawm lub system thiab, yog li ntawd, cov nqe lus nug ntawm payback yog tsis yog li ntawd meej. Thiab yuav ua li cas muaj ntau LED teeb rau lub tsev? Tus nqi ntawm tej khoom yuav nyob ntawm seb lub hwj chim ntawm tus xov tooj ntawm LEDs rau cov kev ruaj ntseg theem. Qhov tsawg kawg nkaus tus nqi yog nyob ib ncig ntawm 5-15 dollars ib feem, zoo saum toj no tau hais tias, muaj yog tsis muaj kev txwv rau zoo tag nrho. Piv txwv li, tus nqi ntawm cov teeb yuav ua tau raws li high school raws li $ 50 apiece, thiab saum toj no.

Lub ntsiab yam ntawm LED teeb

• Nrog voltage ntawm 4 V, feem ntau ntawm cov khoom uas yog siv nyob rau hauv lub teeb, zoo nkauj tswm ciab.
• Nrog 12 V
• Nrog ib tug voltage ntawm 220 V, muaj ntau hom kev kaus mom. LED teeb rau hauv tsev E14, E27, GU10 muaj ib tug built-in transformer, vim li no lawv yuav siv tau ncaj qha nyob rau hauv tus qauv cartridges.

Yuav kom saib lub ntsab lug, peb hais tias tag nrho cov myths xwb thiab tsis sib haum cov lus qhia txog LED teeb yuav nyob twj ywm teeb meem nyob rau hauv lub nyob ze yav tom ntej. Yog li ntawd, cov kev xaiv ntawm cov khoom uas yuav tsum tau mus cautiously, ua tib zoo xyuas los mus xyaum lawv tiag tiag yam ntxwv thiab muaj peev xwm, los ntawm cov kev tsim economic cov kev pab cuam. Peb yuav tsum them nyiaj tshwj xeeb mloog mus rau cov kev kawm txog cov lus qhia txog tej teeb thiab saib rau qhov zoo ntawm cov khoom los ntawm ntau manufacturers. Tsis txhob cia siab rau lub tswv yim ntawm lwm leej lwm tus, txhua yam koj yuav tau mus xyuas koj tus kheej, vim hais tias peb txhua tus yeej paub yuav ua li cas muaj coob tus neeg - yog li ntawd ntau cov kev xav.
