Thaum xaiv LED teeb pom kev zoo rau koj lub tsev cog khoom, lub tsev cog khoom, lossis kev lag luam loj hlob sab nraum zoov, koj puas tau pom cov cim "IP65" lossis "IP67" ntawm daim ntawv qhia tshwj xeeb? Qhov no zoo li tsis tseem ceeb ob - tus lej code tuaj yeem yog qhov sib txawv ntawm koj lub teeb uas kav peb xyoos lossis tsuas yog peb lub hlis xwb.Qhov tseeb IP67 txhais li cas? Thiab vim li cas IP65 tsis txaus rau kev loj hlob teeb?Tsab ntawv xov xwm no piav qhia txog cov qauv thoob ntiaj teb rau kev ntsuam xyuas IP, sib piv qhov sib txawv ntawm IP65 thiab IP67 hauv qhov chaw loj hlob tiag tiag, thiab qhia koj, nrog cov ntaub ntawv thiab qhov tseeb, qhov kev tiv thaiv qib twg tuaj yeem tiv taus ntev ntev - lub sij hawm raug rau cov av noo.
1. Nkag siab txog ob tus lej ntawm qhov ntsuas IP
IP sawv rauKev tiv thaiv Ingress, txhais los ntawm International Electrotechnical Commission (IEC) hauv tus qauv IEC 60529 (tau txais sib npaug li GB / T 4208 hauv Suav teb). Ib tus IP code muaj ob tus lej:
- Thawj tus lej (0–6) : Cov plua plav tiv thaiv qib. "6" yog qhov siab tshaj plaws - tag nrho cov plua plav-tight. Tsis muaj plua plav tuaj yeem nkag mus rau qhov khoom siv.
- Tus lej thib ob (0–9K) : Qib tiv thaiv dej. Cov lej siab dua qhia tias muaj zog tiv thaiv dej, tab sis cov kev sim ntsuas txawv heev.
Table 1: Cov Lus Qhia ntxaws ntxaws rau Kev Ntsuas IP Kev Tiv Thaiv Dej
| Kev ntsuas IP | Kev tiv thaiv plua plav | Txoj Kev Ntsuas Dej | Muaj peev xwm tseem ceeb | Kev txwv tseem ceeb |
|---|---|---|---|---|
| IP44 | Protects against solids >1 hli | Txau dej los ntawm txhua qhov chaw | Lub teeb los nag, yooj yim txaws kuj | Tsis yog los nag lossis jet-proof |
| IP65 | Ua kom plua plav-tooj | 6.3mm nozzle, dej dav hlau los ntawm txhua qhov kev taw qhia, Ntau dua lossis sib npaug li 3 min | Rainproof, low-pressure hose ntxuav | Yuav tsis tau raus dej |
| IP66 | Ua kom plua plav-tooj | 12.5mm nozzle, lub dav hlau dej muaj zog, Ntau dua lossis sib npaug li 3 min | Hnyav hiav txwv, siab-siab ntxuav | Yuav tsis tau raus dej |
| IP67 | Ua kom plua plav-tooj | Immersion ntawm 1m qhov tob rau 30 min | Kev tiv thaiv kev tsis sib haum xeeb | Tsis yog rau immersion ntev |
| IP68 | Ua kom plua plav-tooj | >1m qhov tob, lub sijhawm teev tseg los ntawm cov chaw tsim khoom | Nruam immersion | Tshawb xyuas qhov tob / sijhawm txwv |
(Cov ntaub ntawv xeem raws li IEC 60529 thiab cov ntaub ntawv pej xeem los ntawm cov chaw sim thib peb)
⚠️ Tseem ceeb misconception: IP65 tiv thaiv cov dav hlau tsis tshua muaj dej tab sistsis tawm tsam immersion; IP67 tiv thaiv tiv thaiv lub sijhawm luv luv tab sis tuaj yeemtsis yogtiv taus cov dav hlau siab. Lawv yogtsis interchangeable, los yog nws yog ib qho yooj yim linear upgrade – dhau IPX6 tsis cia li txaus siab IPX5; txhua qib yuav tsum tau txheeb xyuas nws tus kheej.
2. Lub Hnyav Humid Ib puag ncig rau Kev Loj Hlob Teeb - phem dua li koj xav
Kev ua haujlwm hauv tsev cog khoom, cov chaw cog qoob loo, thiab kev cog qoob loo sab nraum zoov yog qhov txawv ntawm qhov chaw sab hauv tsev. Cov av noo nyob ib puag ncig ib xyoos ib zaug, cov dej pos huab los yog cov tee dej muaj nyob rau hauv dej, thiab qee qhov chaw yuav tsum tau ntxuav tsis tu ncua. Thaum cov teeb pom kev zoo hauv tsev LED siv nyob rau hauv ib puag ncig zoo li no, noo noo nkag mus rau hauv cov khoom siv hluav taws xob sab hauv yog thawj qhov ua rau tsis ua haujlwm ntxov.
Siv cov teeb pom kev sib tshuam ua piv txwv. Nroj tsuag transpiration tso tawm ntau cov dej vapor nyob rau hauv lub canopy, ua rau cov txheeb ze humidity mus rau sab saum toj.90%- qee zaum ze saturation. Nyob rau hauv cov cheeb tsam no, lub teeb fixtures tsis yog tas li raug rau high-humidity huab cua tab sis kuj ntsib cov teeb meem nram qab no:
- Condensation cycles: Kub nce thaum nruab hnub, nce transpiration; Thaum tsaus ntuj, qhov kub thiab txias poob thiab dej vapor condenses ntawm qhov chaw teeb tsa, ib ntus "soaking" lub tsev.
- Tshuaj corrosion: Cov huab cua hauv tsev cog khoom tsis yog dej ntshiab - nws muaj cov chiv seem, sulfur fumigants, tshuaj tua kab, thiab lwm yam tshuaj. Qhov no "tshuaj kua zaub" sai sai degrades zoo tib yam sealants thiab yas gaskets.
- Hydroponic txaws: Hauv cov txheej txheem sib sib zog nqus (DFT) cov txheej txheem, cov hauv paus hniav tau txuas ntxiv mus rau hauv cov khoom noj khoom haus. Thaum lub sij hawm hloov dej thiab kev saib xyuas, kev daws teeb meem tuaj yeem cuam tshuam rau lub teeb. Yog hais tias cov yeeb nkab tawg los yog cov qib dej hloov pauv txawv txav, cov teeb yuav raug luv luv.

3. Cov Hom Failure ntawm LED Loj hlob teeb nyob rau hauv qhov chaw siab-Humidity
Ua ntej nkag siab tias vim li cas kev tiv thaiv kev ntsuas tseem ceeb, cia peb saib yuav ua li cas tshwm sim thaum cov teeb pom kev zoo siv rau hauv cov av noo siab:
3.1 LED nti tsis ua hauj lwm - tuag LEDs thiab lumen depreciation
Cov dej noo nkag mus rau LED encapsulation thiab invades lub nti, ua rau luv luv Circuit Court los yog to tam sim no, ncaj qha ua rau tuag LEDs. Txawm hais tias tsis tas tuag, qhov ci ntsa iab, xim kub hloov, thiab flickering yuav tshwm sim. Lub nti ntsuas rau 50,000+ teev yuav pom nws lub neej kev pabcuam poob rauhauv qab 10,000 teevtom qab noo noo ingress.
3.2 Hlau corrosion - lead ncej oxidation
LED coj thiab thav duab feem ntau yog ua los ntawm tooj liab, nyiaj, lossis lwm yam hlau. High humidity accelerates oxidation thiab corrosion, tsim xeb thiab oxide txheej. Corrosion ua rau cov hluav taws xob tsis zoo, cuam tshuam rau kev sib kis tam sim no thiab ua rau flickering lossis tag nrho tsis ua haujlwm. Hauv qhov xwm txheej hnyav, tag nrho cov khoom siv tau raug muab pov tseg.
3.3 Kev nyab xeeb kev nyab xeeb – luv luv Circuit Court thiab to
Rau high-voltage LEDs los yog loj integrated modules, ya raws zoo heev txo cov rwb thaiv tsev tiv thaiv, yooj yim ua rau luv luv Circuit Court los yog to. Qhov no tsis yog tsuas yog ua rau cov neeg tsav tsheb thiab cov tswj kev puas tsuaj tab sis kuj tuaj yeem ua rau hluav taws kub lossis hluav taws xob poob rau hauv qhov xwm txheej hnyav.
3.4 Ntxiv tag nrho cov nqi ntawm cov tswv cuab - hloov tsis tu ncua
Xav txog lub tsev cog khoom nrog 500 lub teeb raj. Lub sij hawm nruab nrab-rau-ua tsis tiav los ntawm noo noo rau IP65 teeb yog nyob ib ncig ntawm 18 lub hlis; rau IP67 teeb, nws yog tshaj 5 xyoos. Kev hloov pauv tus nqi sib txawv yog ntau tshaj qhov kev txiav txim ntawm qhov loj - tsis hais txog qhov poob ntawm kev tsim khoom poob.
