Nws tsis yog tag nrho hu rau LED qhov chaw teeb. Nws yog lub teeb pom kev zoo hluav taws xob nrog nws tus kheej cov yam ntxwv. Tom qab paub txog cov ntsiab lus tseem ceeb, tus nyeem ntawv yuav tuaj yeem xaiv lub cuab yeej, kev siv uas yuav ua tiav tag nrho nws cov kev xav tau thiab kev thov. Nws yuav tuaj yeem ntsuas qhov sib piv ntawm lub zog ntawm cov teeb pom kev zoo thiab cov teeb pom kev zoo LED kom pom qhov chaw ntawm tib cheeb tsam, sib piv cov nqi khoom siv rau qhov no.
Basic parameters of LED teeb
Lub zog ntawm lub teeb tawm los ntawm lub teeb ci yog txiav txim siab los ntawm kev siv hluav taws xob hluav taws xob.
Qhov piv ntawm LED teeb thiab lub teeb incandescent qhia tias rau cov khoom siv uas emitting LEDs ua lub teeb ci, nws yog qhov tsim nyog.siv ntau qhov kev txwv ntxiv:
- tus nqi ntawm cov luminous flux tawm, ntsuas hauv lumens (lm) rau thoob ntiaj teb system ntawm units;
- siv hluav taws xob hluav taws xob los ntawm cov khoom siv LED, ntsuas hauv watts (W);
- qhov ua tau zoo ntawm LED teeb pom kev zoo, uas txiav txim siab tus nqi ntawm luminous flux thaum lub cuab yeej siv 1 W ntawm lub zog hluav taws xob;
- xim kub uas txiav txim siab qhov ntxoov ntxoo ntawm lub teeb tawm (hnub ci, sov dawb, txias dawb);
- hom siv plinth nrog kev faib thoob ntiaj teb;
- ripple yam, nyob ntawm qhov zoo ntawm lub zog hauv cov khoom;
- muab qhov hluav taws xob ntawm 12 lossis 220 volts;
- kev pabcuam lub neej nyob ntawm qhov zoo ntawm cov khoom siv los ntawm cov chaw tsim khoom.
Qee qhov kev txwv ntxiv yuav muaj kev txaus siab rau cov neeg siv khoom thaum siv cov teeb ci LED rau txoj kev teeb pom kev zoo lossis thaj chaw pej xeem. Cov no suav nrog cov chav kawm ntawm kev tiv thaiv kev ya raws, av, kev ua haujlwm kub ntau, kev tiv thaiv kev ua phem ntawm rooj plaub.
LED teeb tsim
Thaum muab piv cov tsos ntawm cov teeb pom kev zoo thiab cov teeb ci LED, koj tuaj yeem pom tsuas yog ib qho kev paub - lub hauv paus, uas yog siv los txuas rau AC mains. Ntawm cov qauv tsim tseem ceeb ntawm LED teeb pom kev zoo (LED teeb), cov hauv qab no tuaj yeem paub qhov txawv:
- matte lub teeb diffuser ntawm ntau yam duab, hloov lub iav qhov muag teev;
- lub teeb-emitting LED diodes nyob rau ntawm lub rooj tsavxwm aluminium es tsis txhob siv cov tungsten filament;
- Powerful finned heatsink ua los ntawm cov hlau conductive heev kom dissipate cua sov los ntawm LEDs;
- tsav tsheb hluav taws xob nyob rau ntawm lub hauv paus, uas yog ib feem ntawm stabilizing kev khiav hauj lwm hom ntawm LED diodes.
Diffuser ua los ntawm cov khoom tawg, hlau heatsink tiv thaiv cov LEDs los ntawm kev poob siab los ntawm kev cuam tshuam sab nraud thiab ua rau cov qauv shockproof.
Ntau yam tsav tsheb
Lub ci ntsa iab tsis tu ncua ntawm LEDs tau lees paub los ntawm kev ntws ncaj qha los ntawm lawv cov qauv. LED diodes tsis tuaj yeem txuas ncaj qha mus rau 220 volt tsev AC fais fab mov. Tus tsim ntawm lub teeb LED muab rau lub xub ntiag ntawm ib tug ntaus ntawv nyob rau hauv nws ua hauj lwm ntawm ib tug tas mus li qhov chaw tam sim no. Nws txo qis qhov hloov hluav taws xob ntawm cov khoom siv sib txuas rau tus nqi xav tau, hloov nws mus rau tam sim no ncaj qha thiab ruaj khov nws tus nqi.
Nyob ntawm lub hauv paus siv los ntawm tus tsim tawm, ntau hom kev tsav tsheb hluav taws xob tuaj yeem paub qhov txawv:
- Circuit Court siv cov capacitors kom nqis AC voltage;
- Circuit Court siv lub kauj ruam-down mains voltage transformer;
- pulse circuits using Pulse Width Modulation (PWM) oscillators.
Thawjob pab pawg muaj rau linear hom tsav tsheb. Lawv txawv los ntawm kev yooj yim ntawm kev sib dhos, lub peev xwm los kho cov khoom tso tawm tsis pub dhau ntau yam los ntawm kev hloov cov kev ntsuam xyuas ntawm cov ntsiab lus suav nrog hauv lawv lub voj voog. Lawv cov nqi kuj tsawg. Pulse circuits siv PWM generators sib sau ua ke ntawm microcircuits hauv ib pob yog qhov ua tau zoo. Lawv coefficient ntawm kev ua tau zoo (COP) nce mus txog 98%.
Yuav ua li cas xaiv tus tsav tsheb LED
Lub luminous flux ntawm lub teeb yuav tsum muab qhov xav tau ntawm qhov teeb pom kev zoo. Rau qhov chaw ua haujlwm, nws yog tsim los ntawm cov cai hauv tsev thiab cov cai (SNiP). Thaum muas LED teeb, nws yuav tsum raug coj mus rau hauv tus account tias cov chaw tsim khoom qhia tag nrho lub zog siv los ntawm cov khoom, uas yog qhov suav ntawm lub zog ntawm LED diodes siv thiab lub zog siv hluav taws xob siv hluav taws xob. Cov neeg tsav tsheb feem ntau siv 1-2 watts.
Nws yog ib qho tsim nyog yuav tsum tau coj mus rau hauv tus account qhov ua tau zoo, uas nyob ntawm tus tsav tsheb. Qhov yooj yim tshaj plaws pheej yig linear hom tsav tsheb tuaj yeem txo nws mus txog 80%. Kev siv matte lub teeb diffusers txo cov luminous flux los ntawm lwm 15-20%.
Tus neeg tsav tsheb tuaj yeem yuav khoom raws li cov khoom tiav tiav lossis sib sau ua ke ntawm nws tus kheej los ntawm tus tsim, uas yog muag hauv ntau lub khw hauv online. Qhov no yuav txuag tau li 20% ntawm tus nqi ntawm LED teeb. Nrog rau txoj kev daws teeb meem no, nws yog ib qho tsim nyog yuav tsum coj mus rau hauv tus account qhov tsis muaj lub zog siab tshaj plaws los ntawm lub cuab yeej, uas yuav tsum tsis txhob tsawg dua lub zog load. Lub Circuit Court yuav tsum muab qhov tso zis voltage thiab kev khiav hauj lwm tam sim no txausrau kev ua haujlwm ntawm LED diodes hauv nominal brightness hom.
Kev sib txawv ntawm ntau hom teeb
Qhov sib piv tiag tiag ntawm cov teeb pom kev zoo thiab cov teeb ci LED qhia tias feem ntau cov neeg siv khoom txaus siab rau kev txuag hluav taws xob thaum tau txais cov teeb pom kev zoo tib yam los ntawm cov teeb pom kev sib txawv. Chav ntsuas rau illuminance yog lux. Tus nqi no yog ntsuas los ntawm ib lub cuab yeej hu ua luxmeter. Nws qhia tau hais tias lub luminous flux ntawm ib lub teeb ci ib 1 m2 ntawm thaj chaw nws illuminates. Lub luminous flux loj dua kuj tsim kom muaj qhov pom kev zoo dua. Qhov ci ntsa iab ntawm cov teeb ci thiab cov teeb ci LED qhia tau hais tias yav dhau los haus txog 8-10 npaug ntau lub zog.
Cov lus saum toj no yog raws li kev siv cov cuab yeej ntsuas tshwj xeeb. Nws muab qhov pom kev sawv cev ntawm qhov piv ntawm lub zog ntawm cov teeb ci, LED thiab lub zog txuag hluav taws xob.
Hloov lub qhov muag teeb nrog LEDs
Qhov kev txiav txim siab tseem ceeb thaum hloov pauv yuav tsum tau muab rau hom lub hauv paus ntawm lub teeb yuav hloov. Lawv yuav tsum muaj tib lub npe raws li kev faib tawm thoob ntiaj teb. Feem ntau ntawm cov no yog E27 thiab E14. Lawv raug ntsuas rau 220V AC fais fab.
Nws raug nquahu kom siv cov npe nrov. Nws yuav ua raws li cov yam ntxwv uas tau tshaj tawm los ntawm cov chaw tsim khoom. Tsis tas li ntawd, koj tuaj yeem them sai sai rau xim kub ntawm lub teeb. Nws sib haum rau lub teeb dawb dawb (4200K), lub teeb sov dawb (2700K) lossis lub teeb txias dawb (6400K).
Qhov zoo thiab qhov tsis zoo ntawm LED teeb
Qhov piv ntawm LED teeb thiab lub teeb incandescent txiav txim siab tias yav dhau los muaj kev siv hluav taws xob qis dua. Nws lub neej kev pabcuam, tshaj tawm los ntawm cov chaw tsim khoom, tshaj 30,000 teev. Qhov no yog qhov zoo tshaj 1,000 teev ntawm kev ua haujlwm tsis tu ncua ntawm lub teeb. Tsis tas li ntawd, nws muaj zog dua txhua yam ntawm lub cev.
Qhov piv ntawm watts ntawm LED teeb thiab cov teeb pom kev zoo qhia tau hais tias nrog tib lub zog siv, lub qub emit ib tug ntau dua luminous flux, thaum tsim illumination ntau dua.
Qhov tsis zoo ntawm LED teeb pom kev niaj hnub no yog lawv tus nqi siab. Cov teeb ci li no tso lub teeb nyob rau hauv ib qho kev taw qhia, uas qhia lawv siv nyob rau hauv lub rooj teeb los yog nyob rau hauv lub qab nthab cov qauv nrog ib tug loj tus naj npawb ntawm emitters ntsia ntawm txawv ces kaum.
Unscrupulous manufacturers feem ntau muab LED teeb rau muag, cov neeg tsav tsheb uas tsis muab ib tug txaus theem ntawm smoothing ntawm DC ripple uas pub cov LEDs. Qhov no ua rau muaj qhov flickering tas li ntawm lub teeb tawm los ntawm lawv, pom qhov muag.
Zoo kawg
Qhov piv ntawm LED teeb thiab lub teeb incandescent yuav tso cai rau tus nyeem ntawv xaiv lub teeb pom kev tsim nyog, suav nrog txhua tus nqi ntawm nws qhov tau txais thiab cov nqi khiav lag luam tom ntej. Tus nqiCia li nco ntsoov tias qhov zoo ntawm cov teeb pom kev zoo ntawm LED teeb tuaj yeem cuam tshuam los ntawm kev dag ntxias kom txuag nyiaj los ntawm kev yuav khoom pheej yig los ntawm cov tuam txhab tsis paub.
