Yuav ua li cas xaiv chav kawm teeb blackboard teeb
Cov teeb hauv chav kawm, teeb pom kev dub, thiab lwm yam, txhua yam yuav tsum tau tsav los ntawm hluav taws xob, yog li cov teeb pom kev hauv chav kawm yuav tsum xaiv cov khoom tsim los ntawm cov tuam txhab tsis tu ncua. Kev xaiv cov teeb hauv chav kawm thiab teeb pom kev dub:
Ua ntej, saib qhov teeb pom kev zoo Lub teeb ci yog ib qho tseem ceeb tshaj plaws uas txiav txim siab qhov zoo ntawm cov teeb pom kev zoo. Tam sim no, cov teeb pom kev zoo hauv khw feem ntau suav nrog cov qhov muag teeb, cov raj fluorescent thiab LEDs. Ntawm lawv, cov teeb ci incandescent yog pheej yig tab sis muaj lub neej luv luv (kwv yees li 1000 teev), thiab muaj peev xwm muaj kev nyab xeeb rau kev siv; Lub teeb fluorescent muaj kev ua haujlwm siab tab sis tsis pub dhau lub neej (kwv yees li 100, 000 teev) thiab cov xim tsis zoo, thiab feem ntau yog siv rau kev kho kom zoo nkauj; LEDs muaj lub teeb pom kev zoo dua Thiab kev tiv thaiv ib puag ncig thiab txuag hluav taws xob (lub neej kev pabcuam tuaj yeem ncav cuag ntau dua 50,000 teev), nws yog qhov zoo tshaj plaws lub teeb pom kev zoo tam sim no.
2. Saib cov xim rendering Performance index CRI hais txog qhov piv ntawm cov duab muaj peev xwm ntawm ib yam khoom ntawm lub retina tom qab raug irradiated los ntawm lub teeb nrog lub teeb tiag tiag. Tus nqi siab dua, qhov ze ntawm cov khoom yog rau cov xim ntuj. Thaum yuav khoom, koj yuav tsum tau them sai sai rau seb cov khoom puas tau cim nrog qhov qhia meej ntawm tus nqi ntawm nws cov khoom?
3. Saib lub hwj chim Fais fab yog ib qho tseem ceeb Performance index parameter uas muaj feem xyuam rau lub illuminance, thiab nws kuj yog ib qho tseem ceeb muaj feem xyuam rau lub hwj chim noj ntawm lub teeb. Feem ntau hais lus, qis dua 40w yog lub zog qis, 60w ~ 120w yog lub zog nruab nrab, 100w ~ 200w yog lub zog siab, thiab siab dua 220w yog ultra-siab zog.
4. Saib ntawm qib kev tiv thaiv. Thaum yuav khoom, koj yuav tsum xyuam xim rau cov hmoov av-pov thawj, noo noo-pov thawj thiab tsis muaj dej tsis zoo ntawm cov khoom?
5. Saib ntawm txoj kev teeb tsa Muaj ob hom sib nqus ballasts nyob rau hauv kev ua lag luam: magnetic nplhaib hom thiab hlau plhaub hom: magnetic nplhaib ballast muaj qhov zoo ntawm qhov me me thiab lub teeb yuag; hlau plhaub hom yog tus cwj pwm los ntawm kev ua haujlwm zoo thaum tshav kub kub dissipation. kev puas tsuaj.
6. Saib ntawm lub hwj huam mov voltage Feem ntau, 220v AC mains tuaj yeem tsav teeb ntawm 40 watts.
7. Ceev faj rau kev yuav khoom
1. Ua ib qho kev xaiv tsim nyog raws li qhov loj ntawm koj chav thiab tag nrho layout
2. Txiav txim siab seb lub teeb yuav xaiv li cas raws li cov teeb pom kev hauv tsev thiab tag nrho cov style
3. Ua tib zoo saib rau txoj haujlwm ntawm lub teeb hloov thiab tswj cov cuab yeej
4. Tshawb xyuas qhov zoo li qhov kev puas tsuaj
5. Xyuas seb cov hlau puas ua tau raws li qhov yuav tsum tau ua
6. Tom qab lub hwj chim rau thiab sim qhov ci, xyuas seb qhov ci ci zoo li cas
7. Ua tib zoo nyeem cov khoom siv phau ntawv
8. Sim mus rau cov khw loj lossis cov khw muag khoom loj mus yuav cov khoom lag luam uas muaj npe nrov
9. Yuav siv thiab tswj kom raug li cas
1. Ua ntej siv, xyuas seb cov khoom puas xoob lossis poob.
2. Thaum siv, tsis txhob kov lub ntsej muag ntawm lub teeb nrog koj txhais tes kom tsis txhob kub hnyiab
3. Tsis txhob txhuam lub teeb nrog ib daim ntaub ntub dej
4. Tsis txhob siv lub teeb rau lub sijhawm ntev ntawm qhov kub siab heev
5. Tsis txhob cia dej nkag rau ntawm lub cuab yeej
6. Yog tias pom muaj qhov txhaum, nws yuav tsum tau hloov raws sijhawm
7. Tsis txhob disassemble thiab kho lub teeb ntawm lub siab nyiam
8. Tsis txhob siv nyob rau hauv ib qho chaw ntub dej
9. Tsis txhob txaws cov kua corrosive rau ntawm lub teeb
10. Txheeb xyuas kab tsis tu ncua
