Mainjiniya ambiri omwe amagwira ntchito m'mafakitalekusintha magetsimakampaniakuchita nawoMphamvu yamagetsi a LEDkupanga. Makampani ambiri ali ndi mitundu itatu yayikulu yopangira magetsi oyendetsa:
Choyamba. Chiyambi ndi mawonekedwe aMphamvu ya driver wa LED
1. Chiyambi chaMphamvu ya driver wa LED
Mphamvu yoyendetsa galimoto ya LED imatanthawuza mphamvu yomwe imasinthidwa kukhala kuwala kwa LED kupyolera mu chosinthira magetsi (monga AC-DC).
Nthawi zambiri, kulowa ndima frequency high-voltage mafakitale ACnthawi zambiri, zomwe timazitcha mains magetsi. magetsi akudziko langa ndi 220V/50HZ, ndipo magetsi aku North America ndi 120V/60HZ; chachiwiri, alipohigh-voltage ndi low-voltage DC, monga 12V, 24V ndi 36V, komanso pali low-voltage high-frequency AC, mongathiransifoma zamagetsitimagwiritsa ntchito voteji yofananira.
2. Mkhalidwe ndi makhalidwe apano aMphamvu yamagetsi a LED
(1)Kudalirika kwakukulu, Nthawi zambiri, chitsimikizo cha nyali zaku North America chimatha kufikira zaka 5, zomwe ndi zabwino.
(2)Kuchita bwino kwambiri, Kugwiritsakusintha magetsikapena liniya magetsi, mphamvu ya 75 ~ 80% ndiyokwera kwambiri.
(3)Mphamvu yapamwamba, kawirikawiri kufika pamwamba pa 0.9, zomwe zikutanthauza kuti zipangizozi zimagwira ntchito zopanda pake, zimagwiritsa ntchito mphamvu bwino, ndipo nyalizo zimakhala nthawi yaitali.
(4) Lili ndi chitetezo chothandiza monga chitetezo cha surge, overvoltage ndi undervoltage.
(5) Lili ndi ntchito zokana fumbi ndi madzi, monga IP44 level.
(6) Ili ndi malamulo otetezeka komanso magwiridwe antchito a electromagnetic.
(7) Madalaivala atatu wamba adzakambidwa pansipa.
Chachiwiri. Zitatu zofananaZida zamagetsi zamagetsi za LED
1. Kusintha gwero lokhazikika
Masiku ano, kugwiritsa ntchito akusintha magetsiKupanga madalaivala a LED ndiye njira yodziwika kwambiri yopangira.
Choyamba, kuchokera ku lingaliro lake la mapangidwe, kuchokera kumapeto kwa zolowetsa, kawirikawiri kupyolera mutransformer yopangidwapalokha, mphamvu yamagetsi yamagetsi yamagetsi yamagetsi ya AC imatsikira kumagetsi otsika (AC-DC), ndipo magetsi okhazikika a DC amatha kutulutsa kudzera pagawo lowongolera. Kuphatikiza apo, EMI fyuluta dera, mawotchi ndi chitetezo mphezi dera, electrostatic chitetezo dera, overvoltage ndi undervoltage chitetezo dera, etc. akuwonjezedwa, ndipo ntchito ndi bwino kwambiri ndipo kudalirika ndi apamwamba.
Kachiwiri, pali mabwalo awiri osinthira nthawi zonse, imodzi ndi dera lodzipatula ndipo linalo ndi lopanda kudzipatula.
Kuchokera ku dzina,dera lodzipatulayapanga midadada ku zigawo zina zamphamvu kwambiri mpaka zotsika mphamvu, zokhala ndi chitetezo chambiri, chitetezo cham'kati mwake, komanso magwiridwe antchito oyipa kwambiri akunja. Chofunikira pagawo lodzipatula ku North America ndi <60Vac.
Winadera losadzipatulaimakulungidwa mu chipolopolo cha pulasitiki chotchingira kunja, chomwe chimakhala chotetezeka, koma mtengo wake ndi wotsika kwambiri kuposa dera lodzipatula. Njira zonsezi zili ndi ubwino ndi zovuta zake.
Chifukwa chake kuchokera pazigawo ziwirizi, zitha kuwoneka kuti magetsi osinthika amakhala ndi chitetezo chabwino komanso magwiridwe antchito okhazikika, omwe ali oyenera kukhala odziwika bwino.Mphamvu yamagetsi a LEDlingaliro lopanga!
Zomwe zimatchedwa mphamvu zamagetsi, monga momwe dzinalo likusonyezera, ndi magetsi a mzere. Kunena zowona, zolowetsa ndi zotulutsa ndizofanana. Mwachitsanzo, nyali zaku North America zimagwiritsa ntchito njira yolumikizira IC, yokhala ndi 120V/60HZ ndi kutulutsa pafupifupi 118V nthawi zambiri.
Zitha kuwoneka kuti kusiyana ndikusintha magetsisikuti voteji imachepetsedwa ndi transformer, koma izoma IC amtundu umodzi kapena angapo amagwiritsidwa ntchito pogawa magetsi(ma IC wamba akuphatikizapo OB5656). Palinso zigawo zochepa, makamaka zigawo za aluminiyamu, m'malo mwa matabwa obiriwira amkuwa amagetsi osinthira magetsi. Mfundo ina ndi yakuti ili ndi mphamvu yapamwamba komanso yogwira ntchito kwambiri, ndipo safuna ma electrolytic capacitors, omwe amakhala ndi moyo wautali kuposakusintha magetsi.
Komabe, chilichonse chili ndi mbali ziwiri. Ngakhale ndizothandiza, zotulutsa zake ndizokwera kwambiri. Munthu akachigwira, chimaika moyo pachiswe, choncho nthawi zambiri chimakhala chipolopolo cha pulasitiki, chomwe chimakhala chotetezeka, koma chovuta kuchichotsa.
3. RC njira yotsika pansi
Zomwe zimatchedwa RC kutsika pansi kwenikweniamagwiritsa Kulipiritsa ndi kutulutsa kwa ma capacitor kuti atulutse magalimoto apanokuyatsa ma LED. Ndi yosavuta kupanga, yosavuta kugwiritsa ntchito, komanso ndiyopanda ndalama. Komabe, abwenzi osamala apeza kuti n'zosavuta kuwononga dera chifukwa cha kuphweka kwake, ndipo pali zinthu zambiri zosakhazikika.
Makamaka m'chilimwe pamene mphamvu ili yochepa, magetsi amazimitsidwa ndi kuyatsanso kawirikawiri kumayambitsa kuwonongeka kwa nyali. Kutulutsa kwake kumakhala kofanana ndi kwa mzere wa IC, ndipo voteji yapamwamba siimalekanitsidwa, choncho ndiyowopsa kwambiri kugwiritsa ntchito. Komabe, chipolopolo chake ndi pulasitiki, motero, chitetezo chake sichili bwino ngati mphamvu yosinthira magetsi.
Kotero mawonekedwe ake ogwiritsira ntchito ndimphamvu yochepanyali, pafupifupi 5W.
Pamafunso azinthu, chonde onanitsamba mankhwala, nanunso mwalandiridwaLumikizanani nafekudzera muzomwe zili pansipa, tidzakuyankhani mkati mwa 24.
