Ib tug liab qab LED sawb yuav luag tsis nyeem raws li ib tug huv kab ntawm lub teeb. Saib ntawm nws ncaj nraim thiab koj pom cov kab sib cais, qhov chaw ci ntsa iab qhov twg txhua lub diode zaum nrog dimmer kwj nyob nruab nrab. Cov neeg tsim qauv hu qhov no dotting lossis hotspotting, thiab nws yog ib qho laj thawj feem ntau qhov ua tiav zoo li pheej yig txawm tias LEDs lawv tus kheej zoo. Qhov kev ntxhov siab yog qhov sib pauv hauv "zoo dua" npog feem ntau yuav luag tsis muaj dab tsi. Tias yog vim li cas LED teeb pom kev zoo yog qhov teeb meem geometry thiab optics ua ntej, thiab cov khoom siv teeb meem thib ob. Tau txais qhov kev txiav txim tsis ncaj ncees lawm thiab koj siv nyiaj rau txheej tsis raug.
Cov lus qhia no taug kev los ntawm plaub lub levers uas tau txav mus rau rab koob, uas yog qhov ceev, qhov deb, cov khoom siv, thiab qhov chaw, nyob rau hauv qhov kev txiav txim tus engineer yuav tsum ncav cuag rau lawv.Peb extrude diffuser profiles rau ib tug nyob, yog li qhov tseem ceeb ntawm no yog qhov tseem ceeb ntawm txhua qhov sib txawv ua li cas, nws raug nqi dab tsi rau koj, thiab qhov twg cov ntaub ntawv txoj cai ntsiag to lov.
Qhov twg cov dots tiag los ntawm
Txhua LED yog qhov chaw sib cais. Nws cuam lub teeb rau hauv lub khob ntawm kwv yees li 120 degrees, thiab ntawm ib lub diode thiab tom ntej no muaj qhov sib txawv uas tsis muaj emitter kiag li. Nyob ze rau ntawm daim kab xev, cov cones tseem tsis tau sib tshooj, yog li koj lub qhov muag nyeem ib ntu ntawm cov peaks ci ntsa iab sib cais los ntawm qhov sib txawv ntawm qhov tsaus nti: pom qhov kub ntawm qhov chaw pom. Tsiv qhov pom qhov chaw deb txaus thiab cov cones ua ke mus rau hauv ib qho kev ntxuav tas li. Tsis muaj dab tsi txog lub npog tau hloov pauv; tsuas yog qhov deb muaj.
Qhov tseeb ib leeg piav qhia tias yog vim li cas peb qhov sib txawv, tsis yog ib qho, tswj hwm dotting: qhov sib nrug ntawm diodes (pitch), qhov kev ncua deb ntawm lub diodes mus rau saum npoo uas thaum kawg qhia lub teeb, thiab yuav ua li cas aggressively lub npog nyob rau hauv nruab nrab ntawm scatters dab tsi dhau los ntawm nws. Lub diffuser tsuas yog qhov thib peb ntawm peb. Kev kho nws raws li tag nrho cov lus teb yog qhov yuam kev uas xa ntau qhov kaj - teeb meem hauv cov voj voog.
Dab tsi "txawm" txhais tau tias yog spec
"Txawm tias" zoo li cov ntsiab lus, tab sis teeb pom kev zoo engineers pin nws nrog qhov sib txawv ntawm qhov ci ci: qhov luminance ntawm qhov ci ntsa iab tshaj tawm tsam qhov tsaus ntuj tshaj plaws, feem ntau tsom ntawm ib ncig ntawm 8: 1 lossis nruj dua rau qhov chaw nyeem zoo li du. Qhov qis dua qhov piv, qhov sib txawv ntau qhov tshwm sim. Tuav nws yuav tsum ntsuas ob lub zog uas rub tawm ib leeg:lub teeb transmittance, uas yog ntau npaum li cas ntawm lumen tso zis ciaj sia lub npog, thiabhaze, uas yog npaum li cas lub npog scatters lub teeb ntawd. High transmittance ua rau lub teeb ci ci; siab haze hides lub diodes. Koj tsis tuaj yeem ua kom tiav ob qho tib si, yog li lub hom phiaj tiag tiag yog lub qhov rais, tsis yog lub ncov.
Ntawm no yog ib feem feem ntau spec ntawv tawm tawm. Diffusion yeej tsis pub dawb. Scattering lub teeb rov qab mus rau hauv vaj tse thiab nqus tau qee qhov txhais tau hais tias lub diffused module feem ntau tsaws ze li 85% ntawm nws tsis muaj-cov ntaub ntawv npog, ib daim duab uas rov tshwm sim hauv cov luminaire luam tawm- diffuser ntsuas, thiab qhov hnyav opal npog cov nqi ntau dua li qhov ntawd.Yog li tiv thaiv cov teeb pom kev ci ntsa iab yog ib txwm ua lag luam tawm tsam kev ci ntsa iab. Qhov sib npaug npaum li cas koj xav tau tsis yog tus lej tas li, txawm li cas los xij: lub hau ntxuav phab ntsa los ntawm ob metres tuaj yeem nyob nrog cov qauv pom tias lub rooj - qhov siab linear fixture saib ntawm caj npab ntev tsis tuaj yeem ua tau, thiab cov teeb pom kev zoo zam lub teeb pom kev ua haujlwm tseem ceeb yuav tsis ua. Pinning tus piv pes tsawg koj fixture yuav tsum ntaus, thiab yog li ntawd ntau npaum li cas brightness koj muaj peev xwm them taus mus yuav nws, yog qhov kev txiav txim hu uas teeb tsa txhua qhov kev txiav txim hauv qab no, thiab nws yog thawj qhov tsim nyog nailing down ua ntej koj kov lub hau.
Kauj ruam 1: LED ceev thiab suab
Qhov ze ntawm lub diodes, qhov sib txawv me dua txhua qhov diffuser yuav tsum nkaum. Qhov no yog vim li cas qhov ntom ntom yog thawj qhov yuav tsum tau kuaj xyuas. Tsawg- strips ceev nyob rau hauv 30–60 LEDs-ib -meter ntau yam tawm hauv qhov tsaus nti dav thiab yog qhov nyuaj rau du; siab - strips ceev ntawm 120 lossis ntau dua LEDs ib 'meter' ntim cov peev txheej ze txaus uas cov cones sib tshooj yuav luag tam sim ntawd, thiab coj cov hotspots loj saib xyuas lawv tus kheej ua ntej yuav muaj kev cuam tshuam.
Kev tshuaj xyuas tus neeg yuav khoom ywj pheej, The Hook Up's dav sib koom LED-channel sib piv (thesmarthomehookup.com), lub rooj ntev zaum- kuaj cov channel thoob plaws txhua qhov ntom ntom thiab ua rau tus nqi tsis quav ntsej qhov tseeb. Ntawm 30 LEDs / m, txawm tias qhov sib sib zog nqus channel ua ke nrog nkhaus "spotless" npog 5 qhov chaw tseem pom, thiab pom 6% qis dua. brightness.Los ntawm 60 LEDs / m, qhov tob tib yam -ntxiv rau-spotless- npog ua ke mus txog ib tug tiag tiag kab txawm nyob rau hauv txhua txhua xim thiab brightness theem, thiab ntawm 144 LEDs / m qhov kub qhov chaw tau ploj mus yam tsis ua hauj lwm ze li ntawm qhov nyuaj.Kev sib ntaus sib tua ib tug sparse strips purely ntawm lub diffuser yog qhov kim tshaj txoj kev uas koj muaj peev xwm hlawv ntawv. ntawm qhov chaw los ntawm kev yuav qhov ntom ntom.
COB strips yog cov ntaub ntawv txwv ntawm lub tswv yim no: ntau pua ntawm cov chips me me nyob rau hauv cov txheej txheem phosphor txuas ntxiv, tsis muaj suab los nkaum. Lawv yog ib tug configuration uas koj muaj peev xwm feem ntau hla hnyav diffusion nkaus thiab tseem tau ib tug seamless kab, txawm ib tug npog tseem khwv tau nws qhov chaw rau kev tiv thaiv thiab glare tswj.
Kauj Ruam 2: geometry, nrug, thiab channel qhov tob
Yog tias qhov ntom ntom tau kho los ntawm ib lub sawb koj twb yuav lawm, qhov kev ncua deb yog qhov tom ntej no - tus nqi qis tshaj, thiab nws yuav luag ib txwm siv tsis tau.Txoj cai ua haujlwm rau kev teeb pom kev zoo yog lub suab coj los npog qhov kev ncua deb ntawm tsawg kawg yog 1: 1: qhov sib txawv ntawm diodes los npog yuav tsum muaj tsawg kawg yog sib npaug ntawm lub suab. Yog hais tias lub suab yog 10 hli, muab lub teeb tsawg kawg yog 10 hli mus ncig thiab lub khob hliav qab muaj chav sib koom ua ke; cia lub suab tshaj qhov kev ncua deb thiab tus kheej diodes pib xuas nrig ntaus los ntawm tsis muaj teeb meem dab tsi npog koj haum. Rau kev zais tob hauv cov vaj huam sib luag backlit, lub teeb - mus rau - diffuser nrug ntawm kwv yees li 1.5 mus rau 2.5 npaug ntawm lub suab yuav ib lub paj zoo nkauj, ntawm tus nqi me ntsis lumen poob thaum lub teeb kis.
Nyob rau hauv ib tug linear fixture, qhov kev ncua deb yog teem los ntawm qhov tob channel, uas yog raws nraim yog vim li cas ib tug sib sib zog nqus aluminium channel hides dots uas ib tug ntiav ib tug tsis tau. Thiab qhov no yog qhov sib txawv uas ntsiag to thim rov qab qhov kev xav li niaj zaus: thaum tus qauv qhia pom qhov ci ntsa iab, cov neeg feem coob ncav cuag qhov kim dua, hazier npog. Feem ntau qhov kev kho pheej yig dua yog ntxiv qhov tob kom lub teeb sib xyaw ua ntej nws puas tau mus txog lub diffuser, txij li cov channel sib sib zog nqus nrog cov npog yooj yim feem ntau ntaus cov channel ntiav nrog tus hwm, rau nyiaj tsawg. Qhov tob npaum li cas yog qhov tshwj xeeb rau koj qhov tsim: nws ntog tawm ntawm koj lub suab thiab koj lub hom phiaj kev sib piv, tom qab ntawd ua lag luam tawm tsam qhov chaw ntawm lub cev thiab qhov sib npaug ntawm cov khoom siv tuaj yeem nqa tau, uas yog lub ntsiab lus uas channel thiab npog yuav tsum tau teev tseg ua ke es tsis yog yuav khoom sib cais.Xaiv ib yam tsis muaj lwm yam yog li cas cov phiaj xwm xaus rau - them raudiffuser profiles tuned rau linear LED fixturesuas yeej tsis mus yeej tawm tsam qhov tob tob.
Kauj Ruam 3: Cov khoom siv thiab lub qhov rais kho qhov muag
Tsuas yog tom qab qhov ceev thiab kev ncua deb tau txiav txim siab cov khoom siv npog pib teeb meem, thiab ntawm no ob lub tshuab ua haujlwm yas sib txawv tiag tiag.
| Khoom | Acrylic (PMMA) | Polycarbonate (PC) |
|---|---|---|
| Lub teeb transmittance (ntshiab, tib tuab) | ~92–93% | ~88–90% |
| Kev cuam tshuam tsis kam | Tsawg dua, nkig | Ntau dua, nyob ze shatterproof |
| Kub kam rau ua | qis | Siab; ruaj khov thoob plaws ntau yam |
| Native UV tiv taus | Zoo dua | Hmoov tsis zoo - daj tsis muaj UV tiv thaiv |
| Yam haum | Sab hauv, optics- ua ntej, yooj yim rau fabricate | Sab nraum zoov, cuam tshuam -nrawm, lossis kub fixtures |
Acrylic kis lub teeb me ntsis ntxiv thiab tuav lub hnub ci ntawm nws tus kheej, uas yog vim li cas optics - coj cov khoom siv sab hauv tsev lean ntawm nws. Polycarbonate muab ob peb lub ntsiab lus ntawm kev xa tawm tab sis yuav siv qhov cuam tshuam thiab cua sov uas yuav tawg acrylic, ua rau nws lub neej ntawd rau sab nraum zoov, pej xeem, lossis siab - qhov kub thiab txias, yog tias nws tiv thaiv UV, vim tias tsis kho PC yellows thiab embrits nyob rau hauv lub hnub.
Tom qab ntawd muaj qhov kev txiav txim siab haze, uas yog qhov ci ntsa iab - qhov chaw tswj tau yeej lossis poob. Raws li txoj cai ntawm tus ntiv tes xoo, lub npog meej tsuas yog 5-10% ntawm cov zis tab sis zais yuav luag tsis muaj dab tsi; frosted npog nqi kwv yees li 15-25% thiab softens cov dots; qhov tseeb opal (milky) npog tus nqi 30-40% lossis ntau dua thiab yog dab tsi thaum kawg ua rau diodes ploj. Kev sib raug zoo ntawm kev tswj hwm yog yooj yim thiab tsis zam txim: qhov ntau diffusing particle koj thauj khoom rau hauv cov khoom, qhov siab dua qhov kub hnyiab thiab qhov zoo dua qhov zais, thiab qhov qis dua qhov transmittance.Transmittance thiab zais fais fab zaum ntawm qhov sib txawv ntawm tib lub dial. Txoj cai ceev rau cov kauj ruam twg los xaiv: nyob twj ywm tsuas yog thaum lub sawb muab zais los ntawm kev pom ncaj qha, mus frosted thaum nws ntsia mus rau hauv ib chav, thiab ncav cuag opal thaum ib tug neeg tuaj yeem ntsia ncaj qha rau hauv nws; cov qhab-nees nyob rau hauv qhov qhab nia yog dab tsi tau hu rau ntawm koj tus lej.Quantifying qhov chaw koj tsaws tsis yog twv ua haujlwm; nws yog ntsuas rauASTM D1003 Kev Tshawb Fawb Kev Tshawb Fawb Kev Tshawb Fawb Kev Tshawb Fawb Kev Tshawb Fawb Kev Tshawb Fawb Kev Tshawb Fawb Kev Tshawb Fawb thiab Kev Tshawb Fawb Kev Tshawb Fawb, yog li tus diffuser tuaj yeem teev rau tus lej ntau dua li kev xav. Qhov kev ua yuam kev kom tsis txhob: chasing qhov siab tshaj plaws xa mus rau qhov ci, tsaws qis dhau ntawm qhov kub hnyiab, thiab nrhiav pom cov chaw kub kub tsis tau ploj mus. Xauv lub qhov rais, tsis txhob maximize ib ntug ntawm nws.
Kauj ruam 4: nto tiv thaiv ntim diffusion, thiab dab tsi extrusion tswj
Ob lub npog tuaj yeem nyeem tib tus xov tooj cua daj cua dub thiab coj txawv txawv, vim tias muaj ob txoj hauv kev kom tawg lub teeb thiab lawv tsis ua rau cov lus qhia.
Nto diffusion, frosted los yog textured daim tawv nqaij, tawg ntawm lub ntsej muag sab nrauv xwb.Nws ua kom kis tau tus mob siab thiab zoo nkaus li huv, tab sis nyias nyias txheej feem ntau tsis tuaj yeem faus qhov chaw muaj zog, yog li cov dots ciaj sia nyob ze saib. Volume diffusion, scattering particles dispersed los ntawm tag nrho cov tuab, khoov lub teeb nyob rau hauv ntau txhiab ntawm internal interfaces, xa deb dua haze thiab ntau zoo zais, ntawm ib tug steeper transmittance nqi.Qhov loj tshaj plaws ua hauj lwm rau nkaum coj chips siv ntim diffusion raws li lub hauv paus thiab tunes nto zoo nkauj nyob rau saum nws.
Qhov no yog txheej txheej ntawm daim ntawv yuav tsis pom thiab tus extruder tswj ncaj qha, thiab nws yog qhov chaw tiv thaiv cov teeb ci ntsa iab dhau los ua kev txiav txim siab tsim khoom ntau dua li kev yuav khoom. Nyob rau hauv extrusion peb teem lub diffusing additive loading rau av transmittance ntawm ib lub hom phiaj, feem ntau stepped nyob ib ncig ntawm 80%, 70%, los yog 60%, es tsis txhob txais txawm ib tug off- lub - txee ntawv tshwm sim.Peb muaj peev xwm dov ib tug micro-textured los yog sawtooth geometry ncaj qha mus rau hauv lub luag hauj lwm ntawm lub teeb thiab geometry. extrusion tawm tom qab. Tsim nyog ua ncaj ncees txog qhov kawg taw tes: rub kab ntawm lub hau extruded tuaj yeem txo qis tab sis yeej tsis tau tshem tawm tag nrho, thiab txhua tus neeg muag khoom uas tau cog lus tias qhov chaw tsis muaj qhov tsis zoo yog overselling.Qhov kho yog tsim, tsis yog khawv koob: txhob txwm tshaj tawm lub ntsej muag tig ib qho khoom cuav uas tsis tuaj yeem ua ib feem ntawm lub tswv yim kho qhov muag.
Ob txheej txheem ntxiab nyob ntawm no ib yam nkaus, thiab ob qho tib si yooj yim rau underrate. Polycarbonate yog noo noo- tshaib plab: peb qhuav nws mus rau kwv yees li 120℃rau peb mus rau plaub teev thiab tuav cov dej seem hauv qab li ntawm 0.02% ua ntej nws puas tau ncav cuag lub hau, vim tias PC khiav ntub dej tshwm sim li nyiaj streaks thiab micro- npuas, thiab ntawm diffuser cov no tsis yog cov tshuaj pleev ib ce tsis zoo ntawm qhov tsis zoo ntawm {5} qhov tsis zoo, tab sis qhov tseeb Muab tso rau hauv ib qho uas koj tab tom sim kho.Peb rub ntev dhau lub rooj tshuaj ntsuam xyuas backlit los ntawm txoj kab ncaj nraim kom ntes tau ib pob streaked ua ntej nws ships es tsis yog tom qab nws tau teeb tsa. Thiab rau txhua qhov chaw sab nraum zoov, kev tiv thaiv UV yog qhov zoo tshaj plaws ntxiv ua co-extruded cap txheej es tsis yog sib xyaw los ntawm ntau, muab kev tiv thaiv raws nraim qhov twg lub hnub hits thiab ua kom tus nqi qis. Cov no yog cov variables uas ua ib qhoextruded polycarbonate diffuser engineered rau kev lag luam teeb pom kev zoocoj kwv yees thoob plaws ib qho kev tsim tawm tag nrho es tsis txhob drifting batch rau batch.
