Ib tug tawg los yog yellowed diffuser feem ntau ncav cuag peb lub rooj ntev zaum tib yam: ib daim duab hauv xov tooj, ib daim kab xev ntsuas nteg hla ib feem, thiab kab"Koj puas tuaj yeem ua qhov no?"Cov lus teb ncaj ncees yog tias daim duab ib leeg tsis tshua tau txais leej twg yog qhov zoo. Lub teeb haum diffuser profile yog kho los ntawm plaub yam ib zaug: nws tus ntoo khaub lig-section, nws qhov kho qhov muag tiav, nws cov polymer, thiab txoj hauv kev nws zaum hauv tsev, thiab tshwj tsis yog tias koj tuaj yeem nyeem tag nrho plaub, txhua nqe lus uas koj tau txais rov qab yog qhov kwv yees. Dab tsi hauv qab no yog qhov kev nyeem ntawv peb cov neeg ua haujlwm daim ntawv thov tau ua haujlwm thaum cov qauv av ntawm no, nteg tawm kom koj tuaj yeem khiav nws tus kheej ua ntej koj xa ib qho kev nug.
Vim li cas cov lus piav qhia yuav luag tsis tau txais koj qhov raug
Ob yam ua rau diffusers tsis yooj yim piav qhia. Thawj yog tias "diffuser" yog lo lus overloaded: tshawb nws thiab koj tsoo nrog HVAC qab nthab diffusers (cov huab cua- tuav troffers uas qhia lub npe thiab tsis muaj lwm yam), ntxiv rau optical patents thiab lub teeb - cov ntaub ntawv tawg, tsis muaj ib qho uas pab tus neeg yuav khoom tuav lub npog tawg. Qhov teeb meem thib ob yog qhov nyuaj dua. Ntau lub npog qub yog lub Hoobkas- tsim rau lub rooj sib txoos uas tau txiav ntev, thiab leej twg tuav lub cuab yeej ploj mus. Cov rooj sib tham saib xyuas lub voj voog tib yam kawg nkaus: lub lens poob, tawg, thiab tus tswv paub tias nws tsis tuaj yeem ua tau zoo, nrog rau kev hloov tag nrho cov khoom siv tau hais tias pheej yig dua li caum ib qho - tawm.
Qhov thib ob scenario yog raws nraim qhov twg nyeem cov diffuser npog profile precisely them tawm, vim akev cai extruder tuaj yeem tsim yuav luag txhua qhov hla -section, tab sis tsuas yog hais tias tus ntoo khaub lig- ntu tau piav qhia raws li tus neeg tuag- tus tsim tuaj yeem ua. Yog li txoj haujlwm ntawm no tsis yog los qhuas ib feem. Nws yog los hloov nws mus rau plaub qhov kev txiav txim tau tseeb.
Pib nrog tus ntoo khaub lig-section, tsis yog xim
Finish yog thawj qhov pom qhov muag thiab qhov kawg uas yuav tsum tau tsav kev txheeb xyuas. Ob lub npog tuaj yeem nyeem tau "milky dawb" thiab tsis muaj dab tsi cuam tshuam. Pib hloov nrog lub silhouette koj yuav pom yog tias koj hlais ib feem thiab saib nws kawg - ntawm, txoj kev koj yuav faib cov teeb pom kev zoo diffuser los ntawm cov duab ua ntej lwm yam.
Feem ntau ntawmcoj profile diffuser homkoj yuav ntsib poob rau hauv ib pawg me me ntawm tsev neeg, kev ua haujlwm taxonomy peb txheeb cov qauv tuaj rau hauv:
| Hla -section tsev neeg | Hom silhouette | Qhov twg nws tshwm |
|---|---|---|
| U-channel (flat-sab saum toj) | Square / rectangular cap hla lub hauv paus qhib | Default rau nto -mounted LED strip channel |
| Curved / arched | Domed lossis ib feem -elliptical saum, qhib puag | Cove thiab indirect khiav qhov twg dot- zais qhov teeb meem |
| V / kaum | Ob lub ntsej muag sib ntsib ntawm ~ 90 degree | Hauv qab - txee thiab txee ntug |
| Round / raj | Kaw C, D, lossis tag nrho lub voj voog | Pendant raj, festoon thiab 360℃fittings |
| Lub teeb / lensed | Asymmetric lossis faceted optical sab saum toj | Beam{0}}shaping rau txoj haujlwm thiab teeb pom kev zoo |
| Flat sheet / vaj huam sib luag | Ib daim ntawv dawb, feem ntau loj | Troffers, wraparounds, poob -ceiling fittings |
| Prismatic / qe-crate vaj huam sib luag | Pyramidal facets los yog ib daim phiaj qhib | Chaw ua haujlwm lag luam thiab fluorescent -retrofit fittings |
Qhov sib cais uas mus ncig ntau tus neeg yuav khoom yog nruab nrab ntawmchannelntiaj teb thiabvaj huam sib luagntiaj teb. LED sawb ua haujlwm nyob hauv thawj plaub tsev neeg; coj mus muag qab nthab fittings, lubfluorescent-era troffers thiab wraparounds, nyob hauv ob lub xeem, nrog lawv tus kheej lub npe nkaus. Ib feem piav tsuas yog "cov diffuser profile" tuaj yeem zaum hauv ob qho tib si, thiab ob qho tib si yog los ntawm cov khoom sib txawv kiag li. Kaw raj seem, C, D, U thiab L cov duab siv rau lub teeb pom kev zoo, yog lawv tus kheej sub- pab pawg dua, extruded li lub voj kaw es tsis yog snap- ntawm lub hau; koj tuaj yeem hla- kuaj lub raj-style npog tiv thaiv tag nrho ntawmkaw-loop tube diffuser duabkom paub meej nws tsev neeg.
Tau tsev neeg txoj cai thiab koj tau tshem tawm feem ntau ntawm qhov tsis meej. Txhua yam tom qab no yog kev kho kom zoo.
Nyeem qhov kho qhov muag tiav thiab cov lej hauv qab nws
Finish yog thawj qhov pom qhov muag thiab qhov kawg uas yuav tsum tau tsav kev txheeb xyuas. Ob lub npog tuaj yeem nyeem tau "milky dawb" thiab tsis muaj dab tsi cuam tshuam. Pib hloov nrog lub silhouette koj yuav pom yog tias koj hlais ib feem thiab saib nws kawg - ntawm, txoj kev koj yuav faib cov teeb pom kev zoo diffuser los ntawm cov duab ua ntej lwm yam.
| Ua kom tiav | Kwv yees li. kev xa tawm | Koj pom dab tsi |
|---|---|---|
| Ntshiab / pob tshab | ~90–95% | Cov zis siab tshaj plaws; tus kheej LEDs pom |
| Frosted / semi- ntshiab | ~85–90% | Dots softened, tso zis NW nyuam qhuav txo |
| Opal / mis nyuj | ~65–75% | Qhov chaw zais; pom cov zis poob |
| Dub (lit) | ~55–60% | Hnyav zais, zoo nkauj -tawm saib |
| Silicone | ~70–75% | Yooj yim, me ntsis clarity |
Frosted thiab opal zoo ib yam li ib nrais muag tab sis ua haujlwm sib txawv, thiab qhov sib txawv ntawd txiav txim siab qhov sib tw. Frosted nto tawg ntawm ib daim tawv nyias nyias los yog sandblasted; ib qho opal npog nqa diffusing hais los ntawm cov khoom siv ntau, uas yog vim li cas nws thiaj nkaum qhov chaw zoo dua thiab raug nqi ntau dua ua nws. Prismatic panels yog cais dua: molded facets uashloov muses tsis yog tawg, tuav kev xa mus ib puag ncig 85-92% thaum tswj glare, uas yog vim li cas cov chaw ua haujlwm tau teev lawv ntev ua ntej LEDs thiab yog vim li cas glare txwv xws liUAS <19tseem tsav qhov kev xaiv ntawd. Yog tias koj xav tau kev lag luam ntev dua - tawm tom qab cov kev ua tiav no, peb cov lus qhia ntawmyuav ua li cas tiav thiab cov khoom lag luam tawm ntawm kev khiav tshiabnpog sab optical; Ntawm no lub ntsiab lus yog nqaim: qhov ua tiav hauv koj txhais tes npe cov chav kawm ua haujlwm uas tus tsim qauv qub tau yuav, thiab pins rau ib qho ntxiv ntawm cov teeb pom kev zoo diffuser profile uas koj tab tom sim kom phim.
Ib txoj haujlwm tsim nyog yuav tsum tsis txhob hais txog, vim tias feem ntau "nws nyob ntawm" cov lus qhia yuav tsis ua: rau txhua yam koj xav kom muaj sia nyob ib lub caij, ua tiav ib leeg tsis yog qhov kev txiav txim siab spec. Ib qho zoo nkauj opal tiav ntawm lub nkig, yellowing substrate yog ib feem koj yuav tau rov qab - qhov chaw hauv ob xyoos. Qhov twg yog cov khoom siv los daws qhov teeb meem.
Qhov polymer qhia koj
Feem ntau koj tuaj yeem nqaim cov khoom nrog peb qhov kev soj ntsuam: nws muaj hnub nyoog li cas, nws flexes li cas, thiab nws zoo li hluav taws kub li cas - ntsuas. Txhua lub ntsiab lus ntawm qhov chaw tshwj xeeb.
Lub npog ploj mus pom daj nyob rau nruab hnub yog yuav luag ib txwm tsis muaj polycarbonate uas poob nws qhov kev sib ntaus sib tua UV lossis, feem ntau ntawm cov khoom pheej yig, PVC.Acrylic (PMMA) tiv thaiv UV yellowing thiab nyob ruaj khov optically, uas yog vim li cas nws dominates khw muag khoom thiab architectural ua hauj lwm qhov twg zoo li yuav tsum tuav rau xyoo; nws kis tau ib ncig ntawm 92% tab sis yog piv rau brittle thiab crazes yog flexed. Polycarbonate pauv me ntsis clarity (~ 88%) rau kev cuam tshuam lub zog ntawm qhov kev txiav txim siab dhau los ntawm acrylic, uas yog vim li cas kev thauj mus los, pej xeem-chaw thiab sab nraum zoov fittings qhia nws yuav luag tshwj xeeb, ntawm tus nqi ntawm kev xav tau UV- qib sab nraum zoov. Silicone khoov qhov twg cov yas tawv tawv tawg, shrugs tawm ntawm cov cua sov tiag tiag, thiab tsis txhob daj, tab sis koj them rau qhov tseeb thiab tus nqi. Qhov ntsuas hluav taws kub yog qhov kawg thiab feem ntau kuaj pom ntawm cov khoom lag luam: lub npog uas yuav tsum tau ua kom tau raws li qhov xav tauUAS 94V-0 lossis 5VA flammability chav kawm yog yuav luag ib qho kev qhia qib engineering, tsis yog lub lens generic.
PVC tsis muaj qhov chaw hauv lub diffuser koj xav khaws cia. Nws yog pheej yig thiab nplaim taws- tiv taus, tab sis nws nqus dej noo, tiv taus cua sov tsis zoo, thiab daj nyob rau hauv lub hlis hauv load. Qhov ntawd tuav ntev npaum li qhov yuav tsum nyob ntev; rau ib qho - tawm ib ntus tso saib nws yog kev tiv thaiv kev txuag, thiab qhov ntawd tsuas yog rooj plaub uas kuv yuav tso nws. Yog li yog tias koj tab tom txheeb xyuas lub npog PVC qub kom rov xaj nws zoo li - rau - nyiam, txheeb xyuas nws, tom qab ntawd hloov kho cov khoom siv. Sib piv geometry tsis yog -negotiable; txuam ib feem ntawm cov cuab yeej phem tshaj tsis yog. Thaum daim ntawv thov tiag tiag xav tau durability, aPC diffuser ua rau kev lag luam thiab sab nraum zoov fittingsyog qhov kev hloov pauv peb yuav ua cuaj npaug ntawm kaum, thiab nws yog qhov hloov pauv uas tib neeg feem ntau tsis nco thaum lawv kho lub teeb haum diffuser los ntawm cov duab ib leeg, tsis muaj rov- nyeem cov khoom.
Qhov haum thiab qhov ntev uas ua tiav qhov kev txiav txim
Zoo, tiav thiab cov khoom tau txais koj ib feem uas zoo nkaus li zoo. Qhov haum yog qhov tau txais koj ib qho ntawdrooj, thiab nws yog qhov uas reorders feem ntau ua tsis tiav, ua - lossis - tawg txheej ntawm txhua lub teeb haum diffuser profile uas koj tab tom sim rov xaj dua.
Diffusers txuas ob txoj hauv kev sib txawv, thiab lawv tsis sib hloov. Snap-hauv (los yog nyem-hauv) npog flex hla lub channel di ncauj thiab nias nyob rau hauv txhua qhov chaw ntawm kev khiav. Swb- nyob rau hauv npog xov los ntawm qhov qhib kawg thiab taug kev ntev. Tsis tseem ceeb- saib, kom txog rau thaum koj ntaus lub ntxiab uas ntes tau txawm tias cov neeg tsim khoom muaj caij nyoog: tus swb- hauv lub lens siv tsis tau rau hauv phab ntsa- rau- phab ntsa recessed qhov, vim tsis muaj qhov qhib kawg los pub nws mus. Koj yuav tsum tau ntxig nws ua ntej cov channel tsim rau hauv qab nthab, thiab thaum lub plaster nce qhov tsis zoo. Snap-nyob rau hauv yog lub neej ntawd kev nyab xeeb rau ib qho chaw recessed los yog twb tau- ntsia channel; swb-nyob rau hauv khwv tau nws qhov chaw nyob rau hauv ncua lossis siab - kev vibration khiav qhov twg nruj dua, pop- lub rooj tiv thaiv yog tsim nyog rau qhov kawg tshem tawm nws xav tau.
Tom qab ntawd plaub qhov kev ntsuas uas yuav tsum tau mus nrog ib qho kev tsocai, vimib tug tuag raug txiav rau lawv:
- dav dav, ntug rau ntug.
- Zuag qhia tag nrho qhov tob / qhov siab, uas tseem teev deb npaum li cas lub ntsej muag diffusing zaum saum qhov chaw.
- Daim di ncauj los yog rov qab los, lub me hooked ntug uas koom nrog lub tsev. Cov yam ntxwv no, ntau dua li lub ntsej muag pom, txiav txim siab seb puas yog qhov clips hauv tsev, thiab nws yog ib daim duab tshaj plaws zais.
- Phab ntsa thickness, uas cuam tshuam rau ob qho tib si diffusion thiab yuav ua li cas qhov flexes ntawm kev teeb tsa.
Ob qhov nyiaj pub ntev ntev ntes cov neeg tawm. Cov kaus mom kawg ntxiv qhov ntev tiag tiag, feem ntau 1/8 "rau 1/4" (3-6 mm) ib lub hau, yog li kev ntsuas ntsuas lub hau- ntsej muag rau lub hau- lub ntsej muag tsis yog qhov ntev rau kev txiav txim. Thiab yog hais tias lub diffuser zaum hla ib qho kev txiav- rau- suab LED sawb, cov channel yuav tsum hwm cov sawb qhov txiav nce ntxiv, feem ntau 50 mm lossis 100 mm, lossis koj tawm ntawm tus Tsov tus tw tsaus ntawm qhov kawg. Qhov tob yog qhov tshwm sim ntawm qhov muag pom ib yam nkaus: txhawm rau tua pom qhov pom, qhov sib txawv ntawm LEDs thiab qhov chaw diffusing yuav tsum dhau qhov sib nrug ntawm cov diodes. Ntawm 30-LED / m strip lub diodes zaum roughly 33 mm sib nrug, yog li ib tug ntiav profile hla ib sparse sawb qhia hotspots txawm yuav ua tau zoo npaum li cas.
Cov yuam kev uas tig ib qho yooj yim reorder rau hauv ib seem seem
Ob peb qhov yuam kev rov tshwm sim feem ntau txaus rau lub npe, vim hais tias txhua tus ntsiag to ua ib feem uas yog geometrically "kho" thiab tseem tsis muaj txiaj ntsig.
Thawj qhov ua tiav -tsuas yog sib txuam: xaj "lwm lub mis" yam tsis tau ntes daim di ncauj geometry, ces pom nws yuav tsis clip rau hauv lub vaj qub qub. Qhov thib ob yog tus swb-hauv- rau hauv-a-recessed- qhov yuam kev saum toj no: lub lens zoo meej uas lub cev tsis tuaj yeem nruab. Qhov thib peb yog orientation ntawm faceted panels. Prismatic diffusers yog kev taw qhia, thiab ntawm fluorescent -style haum lub ntsej muag prismatic (dimpled) musnqes, mus rau hauv chav tsev, kom nthuav tawm lub teeb kom raug; nws yog ib qho kev sib cav ntau xyoo ntawm cov rooj sib tham hluav taws xob thiab tau thim rov qab xav tsis thoob ntau zaus. Qhov thib plaub yog zoo li -rau- zoo li cov khoom siv ntawm ib feem uas yog cov khoom siv tsis raug pib nrog, feem ntau yog PVC. Thiab qhov thib tsib yog qhov nyob ntsiag to: piv txwv tias yog lub Hoobkas tsis txuas ntxiv- lub hau npog tuaj yeem sib phim los ntawm ib qho ncaj- ntawm daim duab, thaum daim di ncauj thiab phab ntsa tuab (ob lub ntsej muag daim duab tiaj tiaj tiaj) yog raws nraim li qhov yuav tsum tau tuag.
Hloov lub hau, hloov lub fixture, los yog re-extrude nws?
Kev txheeb xyuas tsuas yog khwv tau nws khaws yog tias nws xaus rau hauv kev txiav txim siab, thiab qhov kev txiav txim siab tsis yog ib txwm "yuav ib feem ntxiv." Nws feem ntau yog los ntawm cov neeg ua haujlwm hu ua lej txij nkawm, thiab thawj cov tswv yim tsis tshua muaj lub hau. Ib qho tam sim no, tus qauv channel profile dhau lub suab vaj tsev yog qhov yooj yim hu: hloov lub hau, ceev tshaj plaws thiab pheej yig tshaj, nrog rau kev ntsuas qhov yuam kev saum toj no tsuas yog qhov txaus ntshai tiag tiag. Cov lej hloov pauv ib zaug qhov kev sib tw nws tus kheej yog qhov teeb meem. Ib qho khoom siv tsis raug cai uas tam sim no tau noj nws tus thib peb diffuser feem ntau raug nqi tsawg dua los hloov tag nrho, tshwj xeeb tshaj yog tom qab cov kab zais cov khoom neeg ua haujlwm chij: ib chav tsev so yuav xav tau qab nthab ua- zoo, thiab nyob rau hauv ntau thaj tsam swapping ib qho nyuaj -wired fixture yog ib daim ntawv tso cai - hluav taws xob txoj hauj lwm thaum poob rau hauv lub lens tsis yog. Txoj kev thib peb yog qhov ob qhov kev xaiv pom tseeb zais. Thaum koj dhau los ntawm kwv yees li ob peb puas meters ntawm kev khiav, lossis qhov tsis yog - tus qauv, lossis nws yuav tsum tau ua tiav lossis qib hluav taws kub lub txee tsis nqa, rov-extruding profile los ntawm tus qauv lossis kos duab feem ntau pheej yig dua ib chav tsev dua li kev yuav ob zaug, thiab nws yog tib txoj kev uas cia koj kho cov khoom thaum koj nyob ntawm nws.
Spec'ing lub teeb haum diffuser profile yog li nws yog thawj zaug
Thaum koj txiav txim siab kom muaj ib qho rov ua dua tshiab, qhov kev nug uas tau txais cov lus cog lus ruaj khov, tsis yog ib lub lis piam rov qab -thiab- tawm mus, nqa rau yam:
| Spec rau muab | Vim li cas tus neeg tuag- tus tsim khoom xav tau nws |
|---|---|
| Hla -section dav × qhov tob | Teem lub core tuag geometry |
| Daim di ncauj / rov qab profile | Txiav txim siab seb nws zaum hauv lub tsev uas twb muaj lawm |
| Phab ntsa thickness | Tsav diffusion, flex thiab cov khoom ntim |
| Haum hom (snap vs swb) | Paub meej txog kev koom tes geometry |
| Length + kawg -cap allowance | Tsis txhob khiav luv / ntev thiab tsaus tails |
| Finish + khoom qib | Locks transmittance, UV thiab hluav taws kub |
Kho lub rooj li hauv pem teb, tsis yog cov lus teb: kev ua haujlwm siab ntev ntawm txhua kab hloov nrog cov khoom siv thiab phab ntsa tuab. Opal PMMA thiab cuam tshuam PC tsis tuav tib qhov rov qab qhov ntev, yog li cov lej tseeb rov qab los nrog cov qauv, tsis yog ua ntej nws.
Ib qho piv txwv ntaus ib daim duab, thiab ib qho kev kos duab ntaus ib qho kev piav qhia, tab sis ib qho ntawm peb txoj haujlwm ua haujlwm thaum muaj rau daim teb no. Ntawm peb sab uas cov qauv dhau los ua ib qho rov qab -engineered cross-section: peb hauv- lub tsev cuab yeej khw hloov tus neeg siv khoom tus qauv lossis kos duab ua haujlwm tuag nyob rau hauv li 72 teev, hla PC, PMMA, PVC, ABS thiab silicone, pob tshab, opal los yog matte tiav matched rau Pantone siv, nrog V-0es 9 grade 4. Rau sab nraum zoov npog uas yuav tsum tau tiv thaiv yellowing rau xyoo, peb mam li tsim nws raws li ib tugco-extruded UV-stabilized cap hla tus qauv corees tsis yog cia siab rau ib qho resin, ntawm UV-stabilized polycarbonate thiab acrylic qib los ntawm cov chaw muag khoom xws li SABIC, Covestro, Mitsubishi thiab Teijin. Ob xyoo caum ntawm extruding teeb pom kev zoo rau cov neeg siv khoom thoob plaws 50-ntxiv lub teb chaws, nyob ib ncig ntawm 2,000 tons ib xyoo, nyob rau hauvISO 9001 Daim ntawv pov thawjthiab los ntawm peb tus kheej QC lab, txhais tau hais tias qhov tsis txaus ntseeg, qhov tsis siv neeg npog tsis muaj leej twg yuav hais, feem ntau yog qhov niaj hnub no. Yog tias qhov ntawd yog qhov ntawm koj lub rooj zaum, pib akev cai diffuser profile nugnrog ib daim duab thiab rau tus lej ntawd.
