Tam sim no peb tuaj yeem pom cov teeb ci nyob txhua qhov chaw, Hauv txoj kev, khw khw,
Nyob rau hauv lub Hoobkas thiab chaw ua hauj lwm, nyob rau hauv lub vaj thiab lub tiaj ua si ... Thiab ib co coj teeb muaj ib tug tshwj xeeb functionlike coj loj hlob lub teeb uas pab cov nroj tsuag loj hlob sai thiab coj UV teeb uas muaj tshuaj tua kab mob thiab sterilization muaj nuj nqi, Teeb ib tug coj UV teeb nyob rau hauv tsev yuav muaj kev nyab xeeb dua thaum lub sijhawm COVID-19. Kuv tuaj yeem hnov tias cov teeb pom kev zoo nyob ib puag ncig peb.Vim li cas coj lub teeb hloov Incandescent teeb sai sai?
Ua ntej, qhia rau peb paub qhov txawv ntawm Incandescent teeb thiab fluorescent teeb, thiab coj teeb.
● Incandescent teeb
Lub teeb incandescent kuj muaj npe raws li Edison qhov muag teev, Nws ua haujlwm los ntawm kev khiav hluav taws xob los ntawm ib qho filament (tungsten, melting ntawm 3,000 degrees Celsius) uas ua kom sov. Cov kauv ua kom cov cua sov ua kom muaj zog, ua rau cov filament txias mus rau qhov kub ntawm ntau tshaj 2,000 degrees Celsius. Thaum incandescent, lub filament emits lub teeb zoo li glowing liab hlau.Qhov kub ntawm lub filament, lub brighter lub teeb.
Tsis tas li ntawd, Lub teeb xim tsuas yog daj. Thiab cov xim ntawm cov khoom nyob rau hauv lub teeb incandescent tsis txaus tiag tiag (Ra tsawg heev). Lub neej tsis ntev vim yog Tungsten filament sublimation.
●Fluorescent teeb
Nws txoj hauv kev ua haujlwm: lub fluorescent teeb lub raj yog tsuas yog hais tias yog lub raj xa hluav taws xob kaw. Cov roj tseem ceeb hauv lub raj yog argon (argon) roj (uas kuj muaj neon lossis Krypton) ntawm li 0.3% ntawm cov cua. Nws kuj muaj ob peb tee ntawm cov nyiaj - tsim ib lub vapor me me ntawm mercury. Mercury atoms tsim txog ib txhiab ntawm tag nrho cov atoms ntawm cov pa.
Fluorescent teeb muaj qhov zoo ntawm kev ua haujlwm siab luminous (5 npaug ntawm cov qij zoo tib yam), pom kev txuag hluav taws xob, lub neej ntev (8 npaug ntawm qhov muag teev), me me, thiab siv tau yooj yim. Ntxiv rau lub teeb dawb, tseem muaj lub teeb sov. Feem ntau hais lus, nyob rau hauv tib lub wattage, lub teeb txuag hluav taws xob yog 80% txuag hluav taws xob ntau dua li lub teeb incandescent, thiab lub neej nruab nrab yog 8 zaug ntev dua. 5w yog sib npaug rau 25 watts ntawm cov roj teeb, 7 watts yog sib npaug rau 40 watts, thiab 9 watts yog kwv yees li ntawm 60 watts.
●LED teeb
LED teeb tseem hu ua lub teeb-emitting diodes. Nws yog ib qho khoom siv hluav taws xob semiconductor uas tso tawm lub zog hauv daim ntawv ntawm photons thiab ncaj qha hloov hluav taws xob rau hauv lub teeb. Qhov no yog lub hauv paus ntsiab lus ntawm LED teeb pom kev zoo.
LED teeb muaj ntau yam zoo
1. me me
2. Tsawg zog noj
3. lub neej ntev
4. non-toxic
5.kev tiv thaiv ib puag ncig
LED teeb tau maj mam tsim los ntawm kev kho kom zoo nkauj sab nraum zoov thiab engineering teeb pom kev zoo rau cov teeb pom kev hauv tsev.
Tam sim no koj tuaj yeem nkag siab tias yog vim li cas LED teeb thiaj li nrov, thiab hloov lub teeb tsoos sai sai. Raws li cov khoom siv coj teeb, lub teb chaws Yelemees Liper Teeb pom kev zoo yog cov chaw tsim khoom uas muaj kev tshaj lij hauv kev lag luam coj mus rau ntau tshaj 29 xyoo. Los ntawm kev tsim khoom mus rau kev muag khoom, peb muab kev pabcuam ib-nres. Zoo siab txais tos hu rau peb kom paub ntau ntxiv.
