Yuav ua li cas yog lub teeb DRL?

Dua li ntawm qhov rov tshwm sim ntawm lwm cov kev teeb qhov chaw, lub teeb DRL yog tseem yog ib qho ntawm feem nrov dlaws siv rau teeb pom kev zoo uas muaj thaj chaw thiab txoj kev. Qhov no yog vim li thaum koj xav txog qhov zoo ntawm lub teeb pom kev zoo ib yam:

• ntev kev pab cuam lub neej, tshwj xeeb tshaj yog nyob rau hauv tas mus li lag luam (tshwm sim rau txhua gas paug teeb) ;
• High efficiency thiab tseem ceeb lub teeb flux;
• txaus ntseeg ntawm tag nrho cov ntshav.

Nws twb ntseeg tau tias nrog lub advent ntawm lwm txoj kev rau sodium teeb DRL yuav poob lawv txoj hauj lwm, tab sis nws tsis tshwm sim. Yam tsawg kawg vim hais tias ntawm nws cov teeb dawb spectrum yog ntau yam mus rau tib neeg lub qhov muag tshaj li txiv kab ntxwv ntxoov ntxoo lub teeb flux sodium daws teeb meem.

Yuav ua li cas yog lub teeb DRL?

Cov tsiaj ntawv "DRL" sawv rau yog heev yooj yim - ib tug mercury arc teeb. Tej zaum ntxiv tshe cov nqe lus "fluorescent" thiab "kev kub siab". lawv tag nrho cov kev cuam tshuam ib yam ntawm cov yam ntxwv ntawm cov tshuaj no. Nyob rau hauv hauv paus ntsiab lus, cov lus "DRL" koj muaj peev xwm tsis yog tshwj xeeb kev txhawj hais tias ib tug yuam kev nyob rau hauv tus txhais lus yuav tau ua. Qhov no tsiaj tau ntev lawm ib tug neeg hauv tsev neeg lub npe, nyob rau hauv qhov tseeb, lub thib ob lub npe. Los ntawm txoj kev, koj muaj peev xwm tej zaum saib lub sij hawm "teeb DRL 250". Ntawm no, cov xov tooj 250 txhais tau tias noj nqos tau cov hluav taws xob lub hwj chim. Heev yooj yim, raws li cov qauv yuav tsum sib phim uas twb muaj lawm switching khoom.

Lub hauv paus ntsiab lus ntawm cov lag luam thiab cov ntaus ntawv

Teeb DRL yog tsis ib yam dab tsi tag nrho tshiab. Hauv paus ntsiab lus ntawm tiam lub qhov muag pom ultraviolet tawg nyob rau hauv ib tug roj puag ncig nrog hluav taws xob neej puas tau ntev tau paub thiab ntse siv nyob rau hauv fluorescent raj flasks (nco ntsoov "cov neeg tu vajtse" nyob rau hauv peb lub tsev). Hauv lub teeb nyob rau hauv ib tug inert roj nrog ntxiv mercury raj yog ua los ntawm quartz iav rau mas siab kub. Thaum voltage yog thov, thawj ib tug arc ntawm ob zoo spaced electrodes (ua hauj lwm thiab caws nplaum). Yog li pib cov txheej txheem ntawm ionization, lub conductivity ntawm cov kis nce thiab thaum nws nce mus txog ib tug tej yam muaj nuj nqis tshwm sim rau cov thawj arc switching electrode nyob rau lub opposite sab ntawm lub quartz raj. Caws nplaum kev sib cuag nrog cov txheej txheem ntawm los, raws li yog kev cob cog rua ntawm lub tsis kam, thiab yog li ntawd, nws yog tag rau tam sim no.

Main arc tawg ntog rau hauv ultraviolet ntau, uas yog hloov dua siab tshiab rau hauv pom lub teeb los ntawm lub phosphor txheej loj rau lub puab nto ntawm lub hwj.

Yog li, tsis zoo li lub classical fluorescent teeb nyob rau hauv ib tug arc kindling txheej txheem. Qhov tseeb yog hais tias rau qhov pib ntawm ionization yuav tsum tau pib roj neej puas. Yav tas los pulsed hluav taws xob uas muaj peev xwm tsim txaus siab voltage rau lub neej puas tag nrho kis nyob rau hauv ib tug quartz raj, tsis muaj txaus ntseeg, yog li ntawd, cov developers 1970 nyom - muab tso rau hauv cov qauv ntxiv electrodes, nruab nrab ntawm uas tiv cav tseb tshwm sim nyob rau mains voltage. Anticipating lwm lo lus nug hais txog yog vim li cas lub teeb, hlab tawm, tom qab tag nrho, yog tsim siv cov kev zawm caj, cov lus teb - tag nrho ib tug teeb meem ntawm lub hwj chim. Kev noj tubular kev daws teeb meem tsis pub dhau 80 watts, thiab XRD yog tsis muaj tsawg tshaj li 125 watts (ncav 400). Qhov txawv yog palpable.

Thaiv daim duab DRL teeb yog heev uas zoo sib xws rau cov tshuaj siv rau ignition ntawm fluorescent raj teeb pom kev zoo. Nws muaj xws li ib tug series kev cob cog rua caj pas (hluav taws xob tam sim no txwv), thaum uas tig mus-kev cob cog rua capacitors (tshem tawm ntawm cuam nyob rau hauv lub network) thiab lub fuse.
