Pro Amagezi Okutereeza Ebizibu Ebitera Okubaawo mu Kulaga LED Ebweru

Screens eziraga LED ez’ebweru zikyusizza embeera y’obubonero bwa digito n’enkola z’empuliziganya ey’olukale. Olw’engeri gye zikoleddwamu ezigumira embeera y’obudde, okumasamasa okw’amaanyi, n’okukekkereza amaanyi, ebitundu bino eby’okulaga eby’ebweru ebikulembeddwamu bikozesebwa nnyo mu bisaawe, ebipande, siteegi z’okuyita mu bantu, n’ebizimbe by’ebyobusuubuzi. Naye olw’okubeera buli kiseera embeera z’obutonde enkambwe, ne screen esinga okubeera ey’omulembe eyitibwa outdoor led screen esobola okukulaakulanya ensonga ez’ekikugu ezikosa omulimu. Ekitabo kino ekijjuvu kijja kukutambuza mu bizibu mukaaga ebisinga okubeera ebweru led display screen — era kikulage engeri y’okubitereeza ng’omukugu omukugu.

1. okwolesebwa okutali kwa bulijjo mu bitundu bya screen ebitongole nga okozesa screen y’okulaga ebweru led

Obubonero:

• Okukyuka langi ya screen ekitundu

• Ebitundu bya kabineti ebitali bya kuddamu

• Ebbugumu lya langi ezitakwatagana

Okugonjoola:

Nga olaba localized visual anomalies ku outdoor led display screen yo, ensonga etera okubeera mu control system oba receiver cards. Wano waliwo enkola y’okugonjoola ebizibu mu mutendera ku mutendera:

1. Funa ekifo kya kabineti/module ekikoseddwa

2. Kebera amataala ga status ku kaadi ya receiver (kijanjalo kiraga nti zikola bulijjo)

3. Waanyisiganya kaadi za lisiiva eziyinza okuba nga zirina obuzibu ne yuniti ezimanyiddwa ezikola

4. Ddamu okutandika enkola eno era oddemu okupima bbalansi ya langi

Pro Tip:Bulijjo kuuma kaadi za sipeeya eza lisiiva eziweereddwa ekipimo ky’embeera ez’ebweru (-20°C okutuuka ku 60°C) okukakasa nti zikwatagana era nga zeesigika.

2. okukyusakyusa layini empanvu ku kulaga ebweru led

Obubonero:

• Layini ezitakyukakyuka eziwanvuye okubuna olutimbe

• Okukutula ebifaananyi mu kitundu

• Ebikolwa by’okusiba langi

Okugonjoola:

Layini eziwanvuwa zitera okuva ku nsonga z’okuyungibwa wakati wa modulo oba waya. Okugonjoola ekizibu kino ku led display yo ey’ebweru:

1. Kebera ebiyungo byonna ebya waya za ribiini oba tebiriimu oxidation oba okwambala

2. Gezesa data n’ebiyungo by’amasannyalaze ng’okozesa multimeter

3. Amangu ddala zzaawo waya za HUB75 zonna ezonoonese

4. Singa ensonga esigalawo, lowooza ku ky’okukyusa modulo ya LED yonna

Okuziyiza embeera y’obudde Weetegereze:Siiga giriisi ya dielectric ku bifo ebiyunga mu kiseera ky’okuddaabiriza okutumbula obunnyogovu n’okuwangaaza obulamu bw’ekitundu.

3. flashing screen syndrome ekosa ebweru led screen

Obubonero:

• Okuwuuma kw’olutimbe mu ngeri ey’ekifuulannenge

• Okuziba kw’amasannyalaze okutambula buli luvannyuma lwa kiseera

• Enkyukakyuka mu kwakaayakana

Okugonjoola:

Enneeyisa y’okumyansa oba okutambulatambula etera okukwatagana n’amasannyalaze agatali ganywevu. Laba engeri gy'oyinza okukikola obulungi ku screen yo eya led ey'ebweru:

1. Kakasa ebiyungo byonna ebya waya z’amasannyalaze era obiteeke ku 1.5Nm

2. Kozesa mita ya clamp okupima omugugu gw’amasannyalaze gwennyini

3. Yongera ku masannyalaze ag’ebweru aga IP67-rated okusobola okuwangaala obulungi

4. Teeka mu nkola enkola z’okugabanya amasannyalaze agatali ga bulijjo okutangira okulemererwa kw’ensonga emu

Okubala Omugugu:Ebiteekebwamu LED ebweru birina okukolebwa nga birina amaanyi ag’enjawulo waakiri 30% okusobola okubala enkyukakyuka mu bbugumu n’ebiseera by’okukozesa eby’oku ntikko.

4. obutakyukakyuka enzikiza oba ekitangaala emiguwa ku ebweru led display screen

Obubonero:

• Bbandi ezimasamasa/enzirugavu eziyimiridde zirabika ku ssirini

• Ensobi mu langi ezenjawulo mu strip

• Ghosting effects ezirabika wansi w’amataala agamu

Okugonjoola:

Emiguwa egy’enzirugavu oba emitangaavu egy’okwesimbye gitera okulaga nti IC ya ddereeva eremererwa. Goberera emitendera gino okugonjoola ensonga ku screen yo ey’okulaga led ey’ebweru:

1. Siiga ebbugumu erifugibwa (80–100°C) ng’okozesa siteegi y’empewo eyokya ey’ekikugu

2. Zuula IC za ddereeva eziremye ng’okozesa kkamera ekwata ebifaananyi eby’ebbugumu

3. Kikyuseemu chips za TD62783 oba TLC5947 ezitali nnungi

4. Teeka kabineti ezirimu ebintu ebizimbiddwamu ebiziyiza obunnyogovu

Ensonga y’obutonde bw’ensi:Nga 68% ku nsonga za vertical strip zibaawo nga obunnyogovu busukka 80% RH. Kakasa nti empewo eyingira bulungi n’okusiba.

5. okulemererwa enkola okujjuvu okw'okulanga ebweru led okwolesebwa

Obubonero:

• Skirini enjeru nga eriko kaadi y’omuweereza eyakaayakana

• Tewali kuzuula bubonero okuva mu pulogulaamu ezifuga

• Okufiirwa omukutu gw’omukutu

Okugonjoola:

Okwolesebwa kwo okwa led okulanga okw’ebweru bwe kulemererwa ddala, kola diagnostics zino wammanga:

1. Kakasa okuyingiza amaanyi (mu ngeri entuufu 380–480V ku by’okwolesebwa ebinene)

2. Gezesa fiber optic links ne mita y’ekitangaala ey’ekikugu

3. Kikyuseemu waya za network eza CAT6a ezonoonese ezipimiddwa ebweru

4. Teeka ebikuuma amazzi ku layini zonna ezitambuza data

Okukebera okukakasa:Kakasa nti ebitundu byonna bituukana n’omutindo gwa MIL-STD-810G ogw’okuziyiza ensisi n’okukankana naddala ku bifo ebiteekebwa ku kisaawe n’oku nguudo.

6. okusoomoozebwa kw’obutakyukakyuka bwa langi mu kwolesebwa kwa led ebweru

Obubonero:

• Langi etakwatagana mu bitundu eby’enjawulo

• Bbalansi y’abazungu etali ya bwenkanya

• Okukyama kwa gamma curve

Okugonjoola:

Okutuuka ku bumu bwa langi obutuukiridde ku display yo ey’ebweru led:

1. Kozesa spectroradiometer okupima langi entuufu

2. Teekateeka emiwendo gya PWM mu nkolagana ya pulogulaamu y’okufuga

3. Kikyuseemu ebipapula bya LED ebikaddiye mu bitundu ebikwatagana

4. Teeka mu nkola enkola z’okulondoola langi n’okuzitereeza mu ngeri ey’otoma

Enteekateeka y’okuddaabiriza:Kirungi okukola okupima langi enzijuvu buli ssaawa 2,000 ez’okukola okusobola okukuuma omulimu omulungi ogw’okulaba.

olukalala lw’okukebera okuddaabiriza okuziyiza ku screen y’okulaga led ebweru

Okuddaabiriza buli kiseera kikulu nnyo mu kwongera ku bulamu n’omulimu gwa screen yo ey’okulaga led ebweru. Kozesa enteekateeka eno ey’okuddaabiriza sizoni:

• Buli mwezi: Okwoza enfuufu ekuŋŋaanyiziddwa ng’okozesa empewo enyigirizibwa (40–60 PSI) .

• Buli luvannyuma lwa myezi esatu: Kola sikaani z’ebifaananyi eby’ebbugumu okuzuula ebitundu ebibuguma ennyo

• Bi-annually: Gezesa emigugu gy’amasannyalaze era okebere ebiyungo bya grounding

• Buli mwaka: Kebera obulungi bw’ebizimbe n’ebiziyiza amazzi

mu bufunzi

Okukuguka mu bukodyo bw’okugonjoola ebizibu obulagiddwa waggulu kijja kukuyamba okukendeeza ku budde bw’okuyimirira n’okukendeeza ku nsaasaanya ey’ekiseera ekiwanvu ekwatagana n’enkola z’okulaga ebweru ezikulembeddwa. Wadde ng’ensonga nnyingi zisobola okugonjoolwa n’ebikozesebwa ebikulu n’okumanya, okuteeka ebintu ebizibu oba ensobi eziddirira ziyinza okwetaagisa obuyambi okuva mu bakugu abakakasibwa. Teeka mu nkola enteekateeka y’okuddaabiriza era bulijjo kozesa ebitundu ebikyusiddwa eby’omutindo ebipimiddwa embeera ez’ebweru okukakasa nti ekyokulabirako kyo eky’ebweru ekikulembeddwa kigenda mu maaso n’okutuusa omulimu ogw’omutindo ogw’awaggulu omwaka ku mwaka.

Oyagala obuyambi bw'ekikugu ku kwolesebwa kwo okwa led okw'ebweru? Tuukirira abakugu baffe abakakasibwa okufuna okunoonyereza mu bujjuvu n’okuddaabiriza okutuukira ddala okusinziira ku mbeera yo entongole ey’okussaako.
