Txij li thaum 1898, tib neeg tau siv hluav taws xob rau lub teeb tsa tsheb thiab cov teeb cig. Tom qab ntau dua 100 xyoos ntawm kev tsim kho, cov teeb tsa taub hau tsheb tau maj mam tsim cov kab ke tiav. Nrog kev nce qib ntawm thev naus laus zis, tsheb teeb tau dhau los ntawm halogen, xenon, LED Cov qauv hloov ntawm lasers, ntau yam khoom siv teeb pom kev zoo muaj ntau yam kev txwv, txhua tus yuav tsum tsis txhob qauj muag mloog kev tshaj tawm, tus sau hauv qab no yuav qhia cov khoom cov yam ntxwv thiab qhov zoo thiab tsis zoo ntawm ntau lub tsheb teeb.
Keeb kwm ntawm kev siv hluav taws xob halogen nyob rau hauv tsheb tuaj yeem taug qab ntawm 1970 s. Qhov tseeb, nws yog qhov hloov kho ntawm cov roj uas tsis tshua pom tseeb rau kev siv hauv tsev, tshwj tsis yog tias cov khoom sib xyaw halogen tau ntxiv, qhov ci ci tau nce los ntawm 1. 5 lub sijhawm, thiab lub neej tau nce 2-3 zaug Cov. Txog li ob peb xyoos dhau los, hom teeb ci no tseem yog hom teeb ci loj tshaj plaws ntawm cov teeb taws teeb pom kev hauv cov tsheb uas tsim los ntawm cov pib loj cov tsheb. Raws li cov qauv kev teeb tsa ntawm cov tsheb qis, txawm hais tias lub teeb roj halogen muaj qhov tsis txaus ntawm qee yam khoom, vim tias tus nqi pheej yig, nws tseem yog qhov kev xaiv pheej yig heev rau qee tus qauv kev lag luam nrog cov nqi tsawg, tab sis cov teeb no tsis pom zoo rau txhua tus Cov. Cov.
Vim tias niaj hnub no' s txoj kev txhim kho, ntau thiab ntau tus qauv tau maj mam tso tseg kev siv ntawm halogen taws teeb, thiab cov hom loj tau pib nrov ua daim ntawv thov ntawm xenon taws teeb hauv cov qauv qis. Xenon cov teeb pom kev zoo dua peb zaug dua li lub teeb roj halogen, tab sis lawv lub zog siv tsuas yog ob feem peb ntawm lub teeb halogen. Txawm li cas los xij, qhov kev teb tau qeeb, thiab nws siv sijhawm li peb mus rau plaub feeb los taws lub teeb ua ntej kom ua tiav qhov pom kev zoo tshaj plaws. Txawm li cas los xij, txoj ntsiab cai ntawm xenon lub teeb liab txiav txim siab tias qhov kev taw qhia ntawm lub teeb ci yog qhov tsis meej. Yeej, nws yog qhov tsim nyog los nruab lub teeb tsa los ua qhov nqaj irradiation kev coj kom zoo dua.
Cov teeb taws teeb hluav taws xob muaj lub hauv paus ua tiav qhov kev hloov kho tshiab ntawm LED teeb ci
LED ntseeg hais tias cov neeg uas ua tib zoo mloog rau cov zaub yuav tsis paub dua. Lub backlight ntawm hnub no' s kua siv lead ua kua pom yog LED. LED tuaj yeem hloov hluav taws xob ncaj qha rau lub teeb pom kev zoo. Cov hloov dua siab tshiab ua hauj lwm yog heev. Txhua qhov chaw ntawm lub teeb nrig LED suab zoo li qhov siab dua. khoom. Ntau thiab ntau dua cov khoom kim heev tam sim no siv cov LEDs tag nrho raws li lub teeb ci rau cov teeb pom kev zoo, thiab tom qab kev ua lag luam nce qib, ntau hom kuj tau xaiv LEDs rau lub lag luam tsheb me me. Nyob rau hauv kev lag luam yav tom ntej ntawm kev txuag hluav taws xob thiab kev tiv thaiv ib puag ncig, tiv thaiv lub teeb ci LED yuav ua rau lub ntsiab muag.
Lub zog siv hluav taws xob ntawm cov teeb pom kev zoo ntawm LED tsuas yog 1 / 20 ntawm lub teeb halogen, thiab lub neej ua haujlwm tuaj yeem ncav ntau dua 1 00,000 teev. Txhua leej txhua tus yuav tsis paub meej txog lub tswvyim ntawm 1 00,000 teev. Yeej, koj lub tsheb yuav raug pov tseg thiab lub teeb yuav siv tau ib txwm piv nrog xenon taws teeb, lawv me dua qhov loj me thiab tuaj yeem teeb tam sim ntawd, uas muaj kev nyab xeeb heev rau kev tsav tsheb, tab sis qhov yuav tsum tau ntawm LED teeb ua kom zoo rau cov cua sov ua kom muaj cua sov thiab qhov cua yog. kuj kub siab kawg.
Cov teeb taws teeb hluav taws xob laser yog tam sim no kev siv tshuab thev naus laus zis hauv tsheb teeb pom kev zoo. Txhua txoj hauv kev yog qhov pib hloov kho dua tshiab ntawm LED teeb ci. Lawv muaj qhov tshwj xeeb hauv kev hais txog kev deb deb thiab tuaj yeem ncav cuag ntau qhov ntawm 600 meters ua ntej. Irradiated rau 300 meters. Tam sim no, qhov tsis zoo tshaj plaws yuav yog tias tus nqi ntau dhau kom nrov. Plaub yam saum no ntawm cov taws taubhau yog kev qhia paub ntxaws rau txhua tus.
