Nchiyani Chimakhudza Moyo Wautali wa Magetsi a Kuphulika kwa LED?

Nyali yowunikira kuphulika kwa LED ndi mtundu wina wa nyali yopanda kuphulika. Mfundo yake ndiyofanana ndi nyali yotsimikizira kuphulika, kupatula kuti gwero loyatsa ndi gwero la kuunika kwa LED, lomwe limatanthawuza nyali yokhala ndi njira zingapo zapadera zoteteza chilengedwe cha fumbi ndi mpweya kuti usayatseke. Nyali zowunikira kuphulika kwa LED pakadali pano nyali zopulumutsa mphamvu zophulika, zomwe zimagwiritsidwa ntchito m'magetsi a petrochemicals, migodi yamalasha, magetsi, malo amafuta ndi malo ena.

Tonsefe tikudziwa kuti magetsi ophulika a LED ali ndi zotsatira zabwino zopulumutsa mphamvu komanso kuwala kwabwino. Nanga ndi chiyani chomwe chimakhudza moyo wamagetsi owunikira kuphulika kwa LED, ndipo kukonza kungabweretse bwanji phindu?

Zinthu zingapo zomwe zimakhudza moyo wa nyali zowunikira kuphulika kwa LED:

1. Ubwino wa chingwe ndicho chinthu choyambirira chomwe chimatsimikizira kukhala ndi nyali ya LED yopanda kuphulika

Pakapangidwe ka tchipisi cha LED, kuipitsidwa kwina kwa ion, zolakwika zazitsulo ndi njira zina zamakono zimakhudza moyo wawo. Chifukwa chake, kugwiritsa ntchito zingwe zapamwamba za LED ndiye vuto lalikulu.

Nyali ya Keming yopanga kuphulika imagwiritsa ntchito mkanda umodzi wamphamvu kwambiri wa nyali yotsanzira lumen ndi kapangidwe kakang'ono ka chip. Chitsime chowunikira cha LED chopangidwa mwapadera chimakhala ndi kuyerekezera koyunifolomu, kufalikira kwa kuwala kwakukulu ndi kunyezimira pang'ono.

2. Kukonzekera kwa nyali ndi nkhani yofunika kwambiri yomwe imakhudza moyo wa nyali zowunikira kuphulika kwa LED

Kuphatikiza pakukumana ndi zisonyezo zina za nyali, mapangidwe oyatsa nyali ndichinthu chofunikira kwambiri kuthana ndi kutentha komwe kumatulutsa LED ikayatsidwa. Mwachitsanzo, magetsi ophatikizika opangira magetsi pamsika (osakwatira 30 W, 50 W, 100 W), gwero lowala lazogulitsazi komanso njira yolumikizirana ndi kutentha sikusalala, chifukwa, zinthu zina zimayambitsa kuwala pambuyo pa miyezi 1-3 yakuunikira. Kuvunda kumakhala kopitilira 50%. Zogulitsa zina zikagwiritsa ntchito chubu yamagetsi yotsika pafupifupi 0.07 W, chifukwa palibe njira yodziyimira pakatenthedwe, kuwala kumawonongeka mwachangu kwambiri. Izi zitatu zomwe sizopanga zimakhala ndiukadaulo wotsika, mtengo wotsika komanso moyo wawufupi.

3. Mphamvu yamagetsi ndiyofunika kwambiri pamoyo wa nyali ya LED yophulika

Kaya magetsi a nyali ndi ololera amakhudzanso moyo wake. Chifukwa LED ndi chida choyendetsedwa pakadali pano, ngati magetsi pano amasinthasintha kwambiri, kapena kuchuluka kwa ma spikes amagetsi kumakhala kwakukulu, zimakhudza moyo wa gwero la kuwala kwa LED. Moyo wamagetsi wokha umatengera ngati kapangidwe ka magetsi ndi koyenera. Pogwiritsa ntchito kapangidwe ka magetsi, moyo wamagetsi umadalira moyo wazinthuzo.

4. Mphamvu ya kutentha kozungulira pa moyo wa nyali zowunikira kuphulika kwa LED

Moyo wamfupi wapano wa nyali za LED makamaka chifukwa chakanthawi kochepa kwamagetsi, ndipo moyo wawufupi wamagetsi ndi chifukwa chakanthawi kochepa ka electrolytic capacitor. Mbali ina ya cholozera cha moyo cha ma electrolytic capacitors ndikuti iyenera kuwonetsa moyo womwe uli pansi pa kutentha kwa malo okhala madigiri angati, ndipo nthawi zambiri umatchulidwa ngati moyo womwe umakhala pansi pamawonekedwe ozungulira a 105 ℃. M'munsi kutentha kozungulira, nthawi yayitali moyo wautumiki wa capacitor. Ngakhale wamba wa electrolytic capacitor wokhala ndi moyo wa maola 1,000 amatha kufika maola 64,000 kutentha kozungulira kwa 45 ° C, komwe kumakwanira nyali wamba ya LED yokhala ndi moyo wa maola 50,000. Anagwiritsa ntchito.

Kukonzekera tsiku ndi tsiku kwa magetsi ophulika a LED:

Timagula nyali yabwino yopanga kuphulika kwa LED itha kugwiritsidwa ntchito kwa zaka zitatu, koma nthawi zambiri simusamala posamalira nyali ya LED yophulika, chifukwa chake mutha kuyigwiritsa ntchito zaka ziwiri zokha, zomwe ndi Kugwiritsa ntchito ndalama zambiri, timapanga bwanji nyali ya LED yopanga kuphulika Kutalika kwa moyo ndikofunika, tiyeni tikambirane mwachidule zinthu zingapo pansipa:

1. Nthawi zonse tsukani fumbi ndi zinyalala zina zapanyumba ya nyali (ngati sizitsukidwa kwa nthawi yayitali, fumbi limamatira ku nyali kuti izitchinga kutentha kotulutsidwa ndi nyali, zomwe zimapangitsa kuti kutentha kusasokonezeke. nyali yotulutsa kuphulika kwa LED Kutulutsa bwino kutentha), kutaya bwino kutentha ndikofunikira pakukulitsa moyo wa LED.

2. Kukonza mosalekeza komanso kutseka kwa nyali. Ndikulimbikitsidwa kuti nyali zisamagwire ntchito mosadukiza kwa maola 24, chifukwa kutentha kwa nyali kudzawuka pang'onopang'ono pakamagwira ntchito mosadodometsedwa. Kutentha kwakukulu, kumakhudza kwambiri moyo wa nyali. Kutentha kumakulira, ndikufupikitsa moyo wa nyali. .

3. Chivundikiro chofiyiracho chimatsuka fumbi ndi zinyalala zina pafupipafupi kuti zitsimikizire kuwunika

4. Nthawi zonse yang'anani mphamvu ya dera. Ngati magetsi ali osakhazikika, dera liyenera kusamalidwa ndikukonzedwa.

5. Kutentha kozungulira kwa nyali zowunikira kuphulika kwa LED sikuyenera kukhala kopitilira 60 madigiri, ndipo moyo wautumiki ungafupikitsidwe mwachindunji ndi 2/3 ngati ndipamwamba kuposa madigiri 60.

6. Nyali ziyenera kuyatsidwa nthawi zonse mukamagwiritsa ntchito nthawi zonse.
