Kungani agqoke LED isibani nge izibani off? Ezinye izinto okungenzeka futhi izixazululo inkinga

Namuhla, izibani energy-saving athandwa kakhulu ngenxa yokuphila kwabo isikhathi eside futhi ongaphakeme ugesi ukusetshenziswa. Nokho, babengaliqondi labasibekela, njengoba abathengi abaningi bakhetha LED izakhi ukukhanyisa.

Yiqiniso, wonke umuntu ufuna imali eningi atholwe yidivayisi lisebenze kahle futhi akavumi ukuba nanoma iyiphi inkathazo. Nokho, ngezinye izikhathi kuyenzeka ukuthi ukukhanya eshaywa nge izibani off. Siyini isizathu? Ngingaba ukushiya luminaire ngaphandle ukunakwa? Njengoba sinazo zonke lezi imibuzo uyazama ukuqonda sihloko.

Kungani LED isibani ° ng: Isizathu ezijwayeleke kakhulu

Lokhu ukwehluleka ngokuvamile kwenzeka eziningi amandla ukulondoloza, futhi iningi LED izibani. Lonke iphuzu zedivayisi. Inkinga wukuthi lolu hlobo amadivayisi anikwe amandla zinamandla 12 V. Njengoba yaziwa, singanikezwanga in the amafulethi senethiwekhi. Ukuze imikhiqizo ongasebenza kusukela AC at 220 V, elakhiwa ngo isibani base voltage converters. Zakhiwa capacitor, icala-nokugcina, ukuze kukhona "ukuthungela", nokukhanya iqala kukhanye emva ngokuchofoza inkinobho. Ngakho, ukukhanyisa iyunithi akuyona enikeziwe ngokuqondile kodwa kuphela ngokusebenzisa Converter.

Ukuze uqonde ukuthi kungani Siyafulesha LED isibani nge izibani off, kubalulekile ukuba sicabangele isimiso ukusebenza kwe-inkinobho.

I kwasemuva icushiwe kanyekanye ne ngokucindezelwa, esakhiwa i LED kanye ongaphakeme amandla Resistor. Nge inkinobho izibani off "phinda" Iqhwa uchungechunge ukudla, kodwa ngesikhathi esifanayo ube indlela enjalo liphasisa zamanje encane. Inani lawo enganele ukushaja ngokugcwele ukuqala capacitor achithayo ngonyaka isibani Converter. Ngemva kwesikhathi esithile icala namanje luyakha, futhi kukhona "ukuqala" Isibani. Kodwa ubungako bamandla sincane kakhulu, ngakho amakhefu ukukhanyisa kudivayisi futhi ngokushesha uyacima, konke iyaphindwa futhi. Lokhu ngokuvamile uchaza isizathu esenza Siyafulesha LED isibani nge izibani off. Nokho, kunezizathu eziningi kulolu ukwehluleka. Bona ivamile impela, ngakho musa ukubeka eceleni kwabo.

izizathu ezivamile

Siyaqhubeka cabanga iphutha ukukhanyisa zalapho. Ukuze siqonde ukuthi kungani Siyafulesha LED isibani nge izibani off, kufanele sinake izimbangela iphutha. Mhlawumbe into:

• uxhumano esingalungile noma ukufakwa ohlelweni ukukhanyisa.
• Bewumsebenzi. Uma uthenga ngemali ephansi kakhulu ukukhanya Chinese isibani, akufanele balindele okukhulu kuyo.
• LED izibani inkinobho. Ukhiye ngokuvamile kakhulu ifakwe "flashlight" ezengeziwe elikuvumela ukuba ngokushesha ukuthola ungumthombo wokukhanya ebumnyameni. Inkinga wukuthi LED lusekelwa ngamandla kunethiwekhi eyodwa ne Iqhwa, yingakho izikhathi eziningi ukuphinda wesifunda kungenzeka.
• Sagcina impilo inkonzo izibani LED.

Mhlawumbe lokhu kuchaza ukuthi kungani LED ° ng ukukhanya. Futhi ukuzicabangela mancane amathuba izimbangela ukwehluleka. izimo ezinjalo zenzeka kancane kaningi.

izimbangela

Mancane kakhulu amathuba okuba ukuphendula umbuzo "Kungani ukubaniza ukukhanya LED off" iba enye yalezi amaphutha:

• Ukuze kulimaze noma iyiphi imininingwane kudivayisi chip.
• inethiwekhi iziphazamiso zivame kakhulu. Abakhiqizi akafanga ngenxa ngokweqile amandla yokwanda kwama. Lokhu kwenzeka kakhulu kuyaqabukela, kodwa uma uke ukuya efulethini zonke izibani, inkinga ingase ibe kuwo.
• It wadiliza dimmer. Le divayisi isetshenziselwa ushintsho bushelelezi e ukukhanya egumbini.

Abanye abantu ngokuphelele hhayi ecasulayo uma eshaywa LED isibani nge izibani off, futhi abanye bangase bangaqondi ziwulalelisise. Kodwa ungalokothi uweye lezi zinto ukukhanyisa.

Kungani awanakuziziba Morgan isibani

Uma idivayisi isetshenziselwa ukukhanyisa kwezakhiwo lobuchwepheshe, kungasilethela okungathi sina. Kulokhu, ungakwazi ushiye konke njengoba sinjalo. Nokho, uma kuziwa egumbini lokuphumula, bese ukukhanya agqoke kungabangela enkingeni enkulu.

Iqiniso lokuthi kulokolokoza kuyalimaza kakhulu iso. Uma ekamelweni sonke isikhathi eshaywa ukukhanya, emehlweni ngeke usukhathele ngokushesha, futhi umsebenzi bokusungula uyogcina ingathiyeki. Lokhu kuyingozi ikakhulukazi ezinganeni ezincane.

Futhi nokuqubuka okuphindaphindiwe kungase kubangele kokuquleka nabanesithuthwane e umuntu uhlushwa lokhu isifo esiyingozi. izibani eshaywa abe nomthelela ongemuhle izilwane, ikakhulukazi amakati. Four-ezinemilenze ziqala ukuba baziphathe nexhala futhi ungase uqale ukubonisa ulaka.

Ngakho-ke, uma LED ° ng ukukhanya ngemuva kokucima, kubalulekile ukulungisa inkinga. Futhi ukwenza kanjalo ngokushesha ngangokunokwenzeka. Futhi, kufanele zinakekelwe ukuze blink Chandeliers Coefficient ingeqi 20%. Kuyinto eyanele ukuthenga imitha ukukhanya.

Manje phenya izincomo ukulungisa ukukhanyisa okuyiphutha.

Flashing LED ukukhanya: yini okufanele uyenze?

Indlela yokuqala - ushintsho kwemigomo ukusebenza ngamandla wesifunda kwasemuva. Kunezindlela ezimbili ke zingahlelwa kanjani yilezi:

• Nge ukusetshenziswa ebhodini lapho etholakala Resistor icwecwe futhi LED.
• Uma ixhunywe parallel, lo Resistor ejwayelekile futhi LED-izakhi.

Esimweni sokuqala sizoba isikhathi eside kakhulu ukuba silungise. Kungaba lula nje ukususa kwenkokhelo. Esimeni sesibili, konke kulula kakhulu. Ungazama ukushintsha Resistor ukulishintsha namandla kakhulu. Ngenxa yalesi encishisiwe zamanje ukuthi livela epholisayo, ngakho-ke nje ngeke buthelela.

Lapho esikhundleni Resistor kubalulekile ukucabangela amandla ayo kanye nohlobo ukukhanyisa kudivayisi. Ukuze LED izakhi lokubolekwa efanelekayo nezinkomba 470 noma 680 ohms.

indlela 2

Kulokhu-ke kubalulekile ukuba lelisu uxhumano okucishe kufane nalokhu nezibani izifunda nge ukumelana ongaphakeme. Ngenxa imisinga egeleza ngokusebenzisa kwasemuva ngeke zanqwabelana epholisayo. Kunalokho, iyophuma ngokusebenzisa iketango, kanye ukukhanya uyayeka ukukhanyisa.

Ukuze wenze lokhu, udinga ukuthenga umthamo Resistor ezingekho ngaphezu 2 Watts kanye impedance ngokulinganisa of ohms 50. Ukuze wenze kubelula ukuxhumana ke, kudingeka solder izintambo ukuze okukhiphayo yayo. Ngemva kwalokho, kubalulekile ukuba bahlukanise Resistor. Ngenxa yalesi, kuqala alunge zincipha iphuzu ngalinye nokunamathisela ngomthofu, okwathi ngemva kwalokho Resistor silingo shrinkable tube (kulapho ngcono) Ukumelana avale izindlu.

Njengoba yenziwe ngu neketanga ixhumeke parallel kwesibani. Kunconywa ukusebenzisa lebhokisi lokuxhuma izintambo.

indlela 3

Abanye abantu basebenzisa capacitor esikhundleni sohlelo Resistor. Kulokhu, udinga ukuthenga iyunithi, ogama Amandla 400 V Uxhumano senziwa ngendlela efanayo - ngokulinganisa. Kungcono ukusebenzisa lebhokisi lokuxhuma izintambo.

Lesi yisisombululo elula nephumelelayo ukusiza lokulawula umsebenzi izibani Morgan.

Uma izinkinga ukwahlukanisa

Uma kukhona zamanje ukuvuza, kuba inkinga engathí sina ngokwengeziwe. Kulokhu, kufanele uthola umqhubi oxides pad zihlanzwe. Futhi, kubalulekile ukuba solder uxhumano.

Kwezinye izimo, lamanje 'baqhubeke "ngenxa ukwahlukanisa abampofu, ngakho kufanele uchithe isikhathi esiningi ukucinga ukuvuza. Lapho umugqa kuwufanele umshini, kubuye kube njalo "sidilize". Uma lokhu kwenzeka, khona-ke cishe Inkinga iba wiring ezimbi. Ukuze sithole "break" yayo indlela elula ukusebenzisa multimeter.

Ukwazi ukuthi kungani flashing LED isibani nge izibani off, ungakwazi ukuxazulula le nkinga ngokwakho. Nokho, labo "wena" ngogesi, it is hhayi Kunconywa ukuba ulinge. Kungcono ushayele okuyinhloko. Ingcweti onekhono eyonquma ngeso lenyama, yini isizathu ukwehluleka.
