Chifukwa zikuthwanima anatsogolera nyali ndi magetsi? zingayambitse ndi njira zothetsera vutoli

Lero, mphamvu yopulumutsa nyali ndi otchuka kwambiri chifukwa moyo wawo yaitali utumiki ndi mowa otsika magetsi. Komabe, nuwaphimba, monga koposa ogula amakonda LED zinthu kuyatsa.

Kumene, aliyense amafuna ndalama zambiri yotengedwa ndi chipangizo kuthamanga bwino ndipo sindikufuna vuto lirilonse. Komabe, nthawi zina zimachitika kuti kuwunika kuphethira ndi magetsi. Chifukwa chiyani? Ndingatani kusiya luminaire popanda chidwi? Ndi mafunso onsewa kuyesetsa kumvetsa nkhaniyo.

Chifukwa LED nyali blinks: The chifukwa ambiri

kulephera kawirikawiri amapezeka ambiri mphamvu yopulumutsa, ndipo ambiri anatsogolera nyali. Mfundo lonse chipangizo. vuto ndi kuti mtundu uwu wa zipangizo zimayendera ndi voteji 12 V. Monga amadziwika, si zopezeka mu nyumba ya maukonde. Mankhwala ungatithandizire ku AC mphamvu pa 220 V, anamanga mu nyali converters m'munsi voteji. Iwo zigwirizana wa capacitor, woyang'anira-kusunga, kotero kuti pali "poyatsira" ndipo kuwala kuyamba kuwala pambuyo kuwonekera pa lophimba lapansi. Choncho, kuyatsa wagawo si aziwapatsa mwachindunji koma kokha kupyolera Converter ndi.

Kuti timvetse chifukwa kung'anima LED nyali ndi magetsi, m'pofunika kuganizira mfundo ntchito magetsi a.

backlight ndi adamulowetsa imodzi ndi ofunika, chomwe ndi kutsogozedwa ndi otsika mphamvu resistor. Ndi magetsi kuchokera batani "resets" chandelier unyolo chakudya, koma nthawi yomweyo ngati njira akapitirira panopa yaing'ono. Mtengo wake osakwanira kuti athe mlandu poyambira capacitor oyenerera mu babu Converter. Patapita kanthawi ulamuliro akadali chimamangirira, ndipo pali "kuyamba" nyale. Koma kuchuluka kwa mphamvu ndi chochepa kwambiri, kotero yopuma kuyatsa chipangizo ndipo pomwepo uchoka, ndi chirichonse akubwerezedwa kachiwiri. Izi nthawi zambiri anafotokoza chifukwa kung'anima LED nyali ndi magetsi. Komabe, pali zifukwa zambiri kulephera iyi. Iwo zachilendo, kotero musati kukusalani iwo.

zifukwa Common

Tipitirize kuganizira vuto la mindandanda yamasewera kuyatsa. Kuti n'chifukwa chake kung'anima LED nyali ndi magetsi, muyenera kulabadira zimayambitsa mwina vuto la. Mwina chinthu:

• kugwirizana zosayenera kapena unsembe wa dongosolo kuyatsa.
• Chipango. Ngati inu kugula wotchipa kwambiri Chinese getsi, inu sitiyenera kuyembekezera kwambiri kwa izo.
• LED kuyatsa magetsi. Chinsinsi chake ndi nthawi anaikapo zina "tochi" kuti amalola kuti mosavuta gwero la kuwala mu mdima. vuto ndi kutsogozedwa ndi zoyendetsedwa ndi maukonde limodzi ndi chandelier, ndilo chifukwa nthawi zambiri kubwereza dera angagwe.
• Tinamaliza moyo utumiki wa nyali LED.

Mwina likusonyeza kuti LED blinks kuwala. Komanso zothandiza zimayambitsa zokayikitsa kulephera. zoterezi zimachitika kwambiri.

zingayambitse

Wochepetsetsa funsolo "N'chifukwa chiyani kung'anima anatsogolera kuyatsira" akhala m'modzi wa zolakwa awa:

• Kuwononga chilichonse pa chipangizo Chip.
• zopezera zosokoneza zimachitika nthawi zambiri. Opanga si amene amachititsa kukakhala kwambiri mphamvu. Izi zimachitika kawirikawiri, koma ngati inu munayamba kupita ku nyumba kuchokera magetsi onse, vuto lanu lingakhale mu izo.
• Kuthyoka pansi dimmer. chipangizo Izi ntchito kwa kusintha bwinobwino mu kuwala mchipindamo.

Anthu ena mwamtheradi zosasangalatsa ngati kuphethira anatsogolera nyali ndi magetsi, ndi ena sangamvetsere kwa izo. Koma musachepetse zinthu izi kuyatsa.

Chifukwa sangaunyalanyaze Morgan nyale

Ngati chipangizo ntchito kuyatsa kwa malo luso, zikhoza kubweretsa mavuto aakulu. Pankhaniyi, mukhoza kusiya chirichonse monga izo ziri. Komabe, pamene izo zifika pa chipinda chochezera, ndiye kuunika zikuthwanima zingayambitse mavuto aakulu.

Popeza kuti kukulowa zoipa kwambiri kwa diso. Ngati chipinda nthawi zonse kuphethira kuwala, maso adzakhala asatope mofulumira kwambiri ndi ntchito aluntha kenako angaletsedwe. Izi makamaka zoipa kwa ana aang'ono.

Komanso kubuka mobwerezabwereza hule khunyu kuyima mwa munthu akudwala matenda aakulu. Kuphethira nyali kungasokoneze nyama, makamaka amphaka. Zinayi miyendo kuyamba kuchita zinthu nkhawa kwambiri ndipo amayamba kusonyeza mokwiya.

Chotero ngati LED blinks kuwala pambuyo kuzimitsa, m'pofunika vutolo. Ndipo kutero mwamsanga. Komanso, chisamaliro ayenera kumwedwa zimaphethira chandeliers koyefishienti si upambana 20%. Ndi zokwanira kugula mita kuwala.

Ife tsopano mutembenukire kwa malangizo kwa yokonza kuyatsa wolakwika.

Zikuthwanima anatsogolera kuwala: chochita?

Yoyamba njira - kusintha mu magawo a ntchito dera backlight mphamvu. Pali njira ziwiri za tani anakonza:

• Ntchito bolodi limene ili yaying'ono resistor ndipo anatsogolera.
• Pamene olumikizidwa ku kufanana, muyezo resistor ndi LED-zinthu.

Mbali yoyamba tidzakhala ndi nthawi yaitali kwambiri tinker. Zikanakhala bwino kuti pasakhale mlandu. Ngati chachiwiri, chirichonse chiri chophweka kwambiri. Mungayesere kusintha resistor m'malo wamphamvu kwambiri. Chifukwa ichi yafupika panopa Wochokera condenser, kotero izo basi kudziunjikira.

Pamene kuchotsa resistor n'kofunika kuganizira mphamvu ndi mtundu wa chipangizo kuyatsa. Pakuti LED zinthu aggregates abwino ndi zizindikiro 470 kapena 680 ohms.

njira 2

Pankhaniyi m'pofunika kukhazikitsa kugwirizana yomweyi nyali ndi madera ndi kukana otsika. Chifukwa mafunde osefukira kudzera backlight sadzaweruzidwa atasunga condenser lapansi. M'malo mwake, iwo adzadutsa unyolo, ndipo kuwala zimaleka ziphaliwali.

Kuti tichite zimenezi, muyenera kugula resistor mphamvu osapitirira 2 Watts ndi impedance mwadzina 50 ohms. Kukhala kosavuta kulumikiza izo, muyenera solder mawaya zotuluka ake. Pambuyo pake, m'pofunika kupeza resistor. Pakuti ili, choyamba kukonzedwa m'mbuyo mfundo soldering, kenako resistor Chikoka shrinkable chubu (kwambiri bwino) kukana ndi kutseka nyumba.

Konzekerani ndi unyolo olumikizidwa ku kufanana kwa nyale. Ndi bwino kugwiritsa ntchito bokosi zolumikizanazo.

njira 3

Ena amagwiritsa ntchito capacitor m'malo resistor lapansi. Pankhaniyi, muyenera kugula unit, amene mphamvu 400 V. Kugwirizana analengedwa mu njira yomweyo - mu kufanana. Bwino kugwiritsa ntchito bokosi zolumikizanazo.

Iyi ndi njira yosavuta komanso zothandiza kuthandiza zonse ntchito Morgan nyali.

Ngati mavuto kutchinjiriza

Ngati pali kutayikira masiku ano ndi vuto lalikulu kwambiri. Pankhaniyi, muyenera kupeza oxides wochititsa PAD ndi kuziyeretsa. Komanso, m'pofunika solder kugwirizana.

Nthawi zina, panopa akhoza "kupita" chifukwa cha kutchinjiriza osauka, kotero iwe uyenera kutaya nthawi yambiri kufufuza kuchucha. Pamene mzere uli ofunika makina, izo ndi zonse "agogoda". Ngati zimenezi zachitika, ndiye ayenera vuto lagona Kulumikizana zoipa. Kudziwa ake "yopuma" chophweka njira ntchito multimeter.

Kudziwa chifukwa zikuthwanima anatsogolera nyali ndi magetsi, mungathe kuthetsa vuto nokha. Komabe, anthu amene "inu" ndi magetsi, ndi osavomerezeka kuyetsa. Ndi bwino kuitana mbuye. Mmisiri waluso adzaona ndi apoyera, nanga n'chifukwa kulephera.
