I-apharathasi begodu wesifunda kwesibani Fluorescent

Isibani sikagesi (LL) kuyinto umthombo wokukhanya eyenziwe osenyameni kagesi e konemimoya mercury umusi kanye igesi engaxubani namakhemikhali. Lokhu kuphakamisa le ongabonakali ultraviolet ukukhanya oyibamba phezu ungqimba phosphor camera ngaphakathi ebhodleleni. Umbonisi evamile Fluorescent isibani isikebhe sizinze yidivayisi nge isikebhe sizinze kagesi (EmPRA).

incazelo Kudivayisi futhi LL

izibani Iningi isibani ngaso sonke isikhathi kwadingeka simise cylindrical, kodwa manje kungaba ngesimo sibalo eziyinkimbinkimbi. Ngesikhathi semikhawulweni electrode aboshelwe ke, ikhipha ezihlobene ezinye Kuvunguza izibani intambo ezenziwe tungsten. Basuke soldered kuya izikhonkwane esisogwini ngaphandle, lapho zihlala zinamandla sisetshenziswa.

Negesi aphakathi conductive ngaphakathi LL has a ukumelana ezimbi. It kuzibonakalisa zokunciphisa voltage phakathi electrode eziphikisayo nokwanda kokungabi wamanje okumele kungagcini. Isikimu zokuhlanganisa isibani Fluorescent yakhiwa ballastnik (binda), injongo eyinhloko okuyinto - ukudalwa zinamandla ishayela ezinkulu ukuthungela yayo. Ngaphandle-ke likhona EmPRA ukuziqalela - ziyavutha isibani ibekwe ngaphakathi electrode ezimbili igesi emkhathini inert. Omunye wabo wenziwe bimetal. In the state kokuqala electrode evulekile.

Isimiso ezisebenza we LL

Isifunda ukuziqalela kwesibani Fluorescent usebenza kanje.

1. On the wesifunda is nginomdlandla, kodwa kuqala ngokusebenzisa LL yamanje ngenxa elikhulu ukumelana imvelo. Ngu lemiklamo cathode zamanje sihamba heats kubo. Ngaphezu kwalokho, ibizwa nangokuthi yanikezwa ukuziqalela lapho voltage supply esanele umsuka ngaphakathi osenyameni kukhanya.
2. Lapho amalahle oxhumana ukuziqalela by odlula zamanje ipuleti bimetallic Kuvalwa. Ngemva kwalokho, umqhubi metal kuba, futhi ocucuzayo inqanyulwa.
3. I electrode bimetallic ayaphola phansi kuvula contact. Uma lokhu binda okukhiphayo a high voltage ishayela ngenxa self-inductance, futhi LL ephakamayo.
4. Lenza ngokusebenzisa zamanje isibani elivele ke sehliselwe izikhathi 2, njengoba voltage yonkana inductor uwela. Akwanele kabusha oxhumana ukuziqalela okusalayo evulekile ngokunganaki ngesikhathi omlilo LL.

Icebo ukufakwa izibani luminescent amabili efakwe kwelinye luminaire, kuhilela ukusetshenziswa kwazo kwelulwa binda ezivamile. Basuke ixhumeke chungechunge, kodwa isibani ngamunye efakwe eyodwa ukuziqalela ngokulinganisa.

Ububi kwesibani kuvaliwe valve yesibili, uma kungenzeka omunye wabo kuhlulekile.

Okubalulekile! Ngezibani Fluorescent udinga ukusebenzisa ukushintsha ekhethekile. Ngo amadivayisi kwezimali kokuqala imisinga makhulu, nalabo oxhumene nabo angaba okunamathelayo.

Mpintsha-free Fluorescent izibani ukufakwa: schema

Naphezu eziphansi, ballasts kagesi abe kahle. Kwakumelwe isizathu ukudalwa kagesi ukuthungela (ECG).

Indlela ukugijima LL nge ballasts electronic

Mpintsha-free ukufakwa izibani Fluorescent esenziwe electronic control unit, okudala ukulandelana voltage ushintsho ngesikhathi ukuthungela yabo.

Izinzuzo e-drive wesifunda:

• kungenzeka ukuqala kusukela yisiphi isikhathi ukubambezeleka;
• Asazi badinga omkhulu mpintsha kagesi kanye ukuziqalela;
• akukho izibani engakunaki nokubhuza futhi eshaywa;
• okusezingeni eliphezulu kahle elikhanyayo;
• ukudlala futhi compactness zedivayisi;
• ukuphila enkulu.

ballasts Modern electronic anosayizi icwecwe futhi low power ukusetshenziswa. Zibizwa ngokuthi abashayeli, sifake kumila izibani ezihlangene. Mpintsha-free ukuqala izibani Fluorescent evumela ukusetshenziswa ezivamile ejwayelekile cartridges.

Electronic isikebhe sizinze uhlelo kuguqula i kushintshana voltage inethiwekhi 220 imvamisa high. Okokuqala LL electrode ukufuthelana, bese fed zinamandla okusezingeni eliphezulu. Ngezinye okusezingeni eliphezulu imvamisa kahle luyanda kanye kulokolokoza siqedwa ngokuphelele. Isikimu ukufakwa kwesibani Fluorescent anganikeza ukuqalisa ikhompiyutha noma bushelelezi ukwanda ukugqama. Esimweni sokuqala, ukusebenza kwe-ukuphila electrode is kakhulu ziyancipha.

Voltage anda circuit electronic wadala ngokusebenzisa wesifunda oscillation, okuholela resonance nesibani ukuthungela. Ukwethulwa isifika lula kunalokho kule scheme classical nge mpintsha kagesi. Khona-ke, njengoba voltage Sehlile ukubaluleka wayefisa nokugcinwa khulula.

Voltage ukulungiswa kwananoma wenziwa ibhuloho diode, ngemva kwalokho bese eshelelayo parallel exhunywe capacitor C _1. Ngemva yokuxhuma kwinethiwekhi ngokushesha icala capacitor C ₄ futhi amakhefu dynistor. Ukuqalisa lapho kugamanxa-ibhuloho generator transformer TR ₁ kanye transistors T ₁ ne-T _2. Lapho ukufinyelela 45-50 kHz imvamisa ekhiqizwa usebenzisa resonance serial wesifunda c C _2, C _3, L _1, exhunywe kwi-electrode, futhi isibani wokhela. Kulesi uhlelo Ubuye binda, kodwa ubukhulu lincane kakhulu, okuvumela ukuba ngiyibeke base isibani.

isikebhe sizinze Electronic has ilungise ngokuzenzakalelayo LL njengoba izici ukushintsha. Ngemva kwesikhathi adingekayo bakhathale isibani voltage ngo ukuthungela. Ngo Isikimu EmPRA kuvele ngeke lusebenze, kanye isikebhe sizinze electronic kuhlelwe ngaphansi izici ekushintsheni ngaleyo ndlela sisenze umshini ukuba usebenze e izimo ezikahle.

Izinzuzo ballasts zesimanje ze-elekthroniki zimi kanje:

• isiqalo ezithambile;
• Umnotho wokusebenza;
• kulondolozwe electrode;
• ngaphandle kulokolokoza;
• operability ezingeni lokushisa ongaphakeme;
• compactness;
• ngokuqina.

I yokuntula ezinamanani aphansi ephakeme futhi eziyinkimbinkimbi wesifunda ukuthungela.

Isicelo se-Okuphindaphinda voltage

Indlela wenza sikwazi ukufaka LL kagesi ngaphandle isikebhe sizinze, kodwa okungcono wasebenzisa isikhathi ekuphileni yezibani. Circuit yezibani eshile Fluorescent kubenza bakwazi ukusebenza isikhathi esithile, uma amandla ingeqi 20-40 Watts. Kulokhu intambo kungaba yayinjalo noma kushaywa. Kuzo zombili lezi zimo, iziphetho intambo ngayinye kuyadingeka ukuze isekhethi.

Ngemva ekulungiseni voltage ngokuphindwe kabili, futhi izibani isibani ngokushesha. Capacitors C _1, C ₂ ezikhethiwe ukuze voltage yokusebenza 600 V ethile wabo yobukhulu enkulu. I capacitors C _3, C ₄ ogibele mica 1000 V

LL ayenzelwanga ngqo wamanje ugesi. Ngokuhamba kwesikhathi, mercury aqoqana eduze omunye electrode, kanye kukhanya buthaka. Ukubuyisela ekushintsheni polarity Goal isibani. Kungenzeka ukusetha inkinobho ukuze akusho ukudubula.

Besstarternaya scheme ukufakwa izibani luminescent

Isikimu ukuziqalela kudinga isibani gaphambi eside. Ngaphezu kwalokho, ngezinye izikhathi kudingekile ukushintsha. Kule ndaba, kukhona elinye icebo nge electrode evuthayo ngokusebenzisa yesibili emazombezombe we transformer, liyilo isibili, elona umsebenzi we isikebhe sizinze.

Lapho inkinobho wenziwe izibani Fluorescent ngaphandle ukuziqalela, kufanele RS isiqu (isiqalo okusheshayo). Ilambu ne kwethulwa ukuziqalela ngeke isebenze lapha nje electrode kwakhona evuthayo, futhi kuvunguza ashisiwe ngokushesha.

Indlela uvula isibani wokushiswa?

Uma Kuvunguza awahlelanga, LL kungenziwa luvutha ngaphandle Okuphindaphinda voltage, besebenzisa uhlelo evamile EmPRA. Isikimu unike amandla tho isibani Fluorescent iyahlukahluka kancane kuphela kuqhathaniswa ezivamile. Ngenxa yale njongo, lo capacitor ukuziqalela ixhumeke chungechunge, futhi electrode izikhonkwane kukhona sesiwancamulile. Ngemva onjalo ekuguqulweni nesibani esincane izothatha isikhathi esithile.

isiphetho

Design kanye wesifunda kwesibani Fluorescent is njalo ngcono maqondana emnothweni, ukunciphisa usayizi nekwenyusa ukuphila service. Kubalulekile ababusebenzisela, ukuqonda ezihlukahlukene izinhlobo kukhiqizwa futhi ukwazi izindlela eziphumelelayo ukuxhuma.
