Mukapita ku chipatala chilichonse chomwe sichinasinthe zida zake m'zaka khumi zapitazi, mudzawaona: magetsi ofunda achikasu pang'ono a halogen omwe akumveka pamwamba pa mpando wochitira opaleshoni. Amayatsabe, amapanga kuwala, ndipo akhala odalirika kwa zaka zambiri. Ndiye bwanji kuwononga ndalama m'malo mwa chinthu chomwe chikugwirabe ntchito?
Ndinadzifunsa funso lomweli mpaka mnzanga wina atandionetsa kusiyana kwa bilu yamagetsi atasintha malo ake ochitira masewera olimbitsa thupi atatu kukhalaMagetsi owunikira a LEDManambala anasintha maganizo anga. Izi ndi zomwe ndinaphunzira.
Mtengo Wobisika Wosungira Magetsi a Halogen
Nyali yowunikira ya halogen imaoneka yotsika mtengo chifukwa muli nayo kale. Koma ola lililonse ikagwira ntchito, imakuwonongerani ndalama mwakachetechete zomwe sizimawonekera pa oda yogulira.
Mababu a halogenamasintha pafupifupi 80% ya mphamvu zawo kukhala kutentha, osati kuwala. Chotenthetsera cha 150-watt kwenikweni chimakhala chotenthetsera cha 120-watt pa mkono wolumikizidwa. Mu chipinda chaching'ono choyezera, izi zimapangitsa kuti choziziritsa mpweya chizigwira ntchito molimbika - makamaka nthawi yachilimwe pamene zipatala zikuvutika kale kuti zipinda zikhale bwino kwa odwala.
Kenako pali kusintha mababu. Babu la halogen limatenga maola 1,000 mpaka 2,000. Mu chipatala chotanganidwa, izi zikutanthauza kusintha mababu pafupifupi kawiri pachaka pa chipangizo chilichonse. Mukawonjezera nthawi yobereka, kusokonezeka kwa kulephera kwapakati pa ntchito, ndi zinthu zina zomwe zatsala, ndipo kuwala kwa halogen "kwaulere" kumasiya kuwoneka kwaulere mwachangu.
Kumene Ma LED Exam Lights Akutsogola
Kusiyana koyamba ndi mtundu wa kuwala. Halogen imapanga kuwala kofunda, kwachikasu — pafupifupi 3,000K — komwe kumasokoneza pang'ono mawonekedwe a minofu. Mumaphunzira kubweza, koma imeneyo ndi khama lamaganizo lomwe simuyenera kuwononga.
Magetsi amakono a LED owunikira zachipatala amapereka kuwala koyera kwabwino kwambiri kwa dzuwa komwe kumakhala ndi chizindikiro chosonyeza mtundu (CRI) cha 93 mpaka 98. Mwachidule, izi zikutanthauza kuti kusiyana pakati pa mucosa ya pinki yathanzi ndi minofu yotuwa yokayikitsa kumawonekera nthawi yomweyo m'malo mwa chinthu chomwe mumachiyang'ana mozama. Pa matenda a khungu, matenda a akazi, matenda a ENT, ndi matenda aliwonse ozindikira matenda, izi zokha zimatsimikizira kukwezaku.
Kupatula mtundu, magetsi oyesera a LED opanda mthunzi amafalitsa ma diode angapo pamalo akuluakulu, zomwe zimachepetsa mithunzi yoopsa ya mfundo imodzi yomwe imakhudza mapangidwe a halogen ya babu limodzi. Kusasintha pang'ono panthawi ya mayeso kumatanthauza kupambana pang'ono komwe kumawonjezera odwala ambiri tsiku lililonse.
Manambala Omwe Amatseka Mlanduwu
Kuwala kwa LED kwabwino kwambiri kumakoka ma watts 20 mpaka 50 pomwe kumafanana ndi halogen ya 150-watt - kuchepetsa magetsi ndi 70 mpaka 80%. Kutentha kochepa m'chipinda kumatanthauza kuti mpweya wozizira umakhala wochepa, ndipo mu chipatala chokhala ndi zipinda zambiri, izi zimawonekera pa bilu yamagetsi ya mwezi uliwonse.
Nthawi ya moyo ndi chiwerengero chomaliza. Mababu a LED a kalasi yachipatala amawerengedwa kuti ndi maola 40,000 mpaka 80,000 — maola asanu ndi atatu patsiku, zomwe zikutanthauza zaka 14 mpaka 27 asanawonongeke. Yerekezerani zimenezo ndi kusintha mababu a halogen miyezi isanu ndi umodzi iliyonse, ndipo mtengo wonse wa umwini umasinthidwa m'malo mwa LED mkati mwa zaka ziwiri kapena zitatu, zomwe zimapangitsa kuti mtengo wogulira ukhale wokwera. Ma LED amapereka CRI ya 93 mpaka 98 poyerekeza ndi pafupifupi 85 mpaka 90 ya halogen, ndi mphamvu yochepa kwambiri yotulutsa kutentha. Kwa zaka zisanu, LED imodzi imapewa kusintha mababu pafupifupi khumi omwe halogen ingafunike.
Zoyenera Kuyang'ana Mukakweza
Si magetsi onse oyesera a LED omwe ali ofanana, ndipo kutsatsa kotsika mtengo pamsika nthawi zambiri sikoyenera kwa akatswiri azachipatala.
Kutentha kwa mtundu komwe kungasinthidwe n'kofunika kulipira. Kusintha pakati pa kutentha (pafupifupi 3,800K) ndi kuzizira (mpaka 5,500K) koyera kumakupatsani mwayi wogwirizanitsa kuwala ndi njira: kutentha kuti muwone bwino, kuwala kozizira kwa masana kuti muwone bwino kwambiri. Machitidwe monga Micare E500 Multi-Color series amakulolani kusintha njira zingapo zamitundu ya LED paokha kuti muwongolere bwino.
CRI iyenera kukhala osachepera 93. Pansi pa 90 ndipo mukuphonya phindu lozindikira lomwe limapangitsa kuti halogen isinthe. Zida zapamwamba - kuphatikizapo nyali yowunikira ya Micare JD1800L Plus - zimapeza CRI ya 96 kapena kupitirira apo ndi R9 deep red rendering pamwamba pa 90, yofunika kwambiri powonetsa kapangidwe ka mitsempha yamagazi.
Kukhazikitsa malo oimikapo zinthu n'kofunika kwambiri kuposa momwe zipatala zambiri zimaganizira. Magetsi oyendera a LED oyenda pa malo oimikapo zinthu amapereka kusinthasintha pakati pa zipinda. Magetsi oyezera oikidwa pakhoma amasunga malo pansi m'zipinda zazing'ono. Magetsi oyezera oikidwa padenga amakwanira zipinda zapadera zoyezera zinthu. Mndandanda wa Micare wa JD umaphatikizapo zonse zitatu, kotero zipatala zimatha kuyika mtundu umodzi wofanana ndi kapangidwe ka chipinda chilichonse.
Ziphaso siziyenera kukambidwanso: Kulemba chizindikiro cha CE pansi pa MDR 2017/745, ISO 13485. Izi si zizindikiro zotsatsa malonda - zimatsimikizira kuti kuwala kwayesedwa malinga ndi miyezo yachipatala.
Zinthu Zachilengedwe
Mababu a halogen alibe mercury, kotero kutaya mababu sikoopsa kwambiri kuposa njira zakale zowunikira. Koma kuchuluka kwa mababu omwe chipatala chimataya kwa zaka khumi kumawonjezeka. Chojambulira cha LED chimachotsa zinyalalazo pafupifupi zonse. Kuchepetsa mphamvu kumatanthauzanso kuchepa kwa mpweya woipa - ndipo mochulukira, odwala ndi ogula mabungwe amaika kukhazikika kwa zinthu zomwe amapereka.
Kupanga Kusintha Kothandiza
Simukuyenera kusintha magetsi onse usiku wonse. Yambani ndi chipinda chanu choyesera chomwe chili ndi anthu ambiri, ikani nyali yabwino kwambiri ya LED, ndipo tsatirani momwe mababu amasinthira magetsi ndi momwe amagwiritsidwira ntchito kwa miyezi isanu ndi umodzi. Deta idzapanga chivundikiro cha chipinda china.
Gulani kuchokera kwa wopanga yemwe amasamala kwambiri za magetsi azachipatala, osati wogulitsa wamba. Zipangizo zamankhwala zimapangidwa kuti zigwirizane ndi kuyeretsa, kapangidwe ka mpweya wochepa, kulumikizana kolondola komwe kumasunga malo ake popanda kusuntha, komanso njira zina zosungira batri. Nanchang Micare Medical Equipment — wopanga wovomerezeka ndi ISO 13485 ndi CE MDR — wakhala akuyang'ana kwambiri magetsi azachipatala kwa zaka zambiri. Magetsi awo oyendera ndi magetsi opangidwa ndi JD series ndi magetsi opangidwa ndi opaleshoni amatumizidwa kumayiko opitilira 100 ndi chitsimikizo cha zaka zitatu.
Nyali yanu yoyezera ya halogen ikugwirabe ntchito. Koma "ikugwirabe ntchito" si "chisankho choyenera." Masamu a LED atsimikizika: mtengo wotsika wogwirira ntchito, kuwoneka bwino kwachipatala, komanso chipinda choyezera chozizira. Funso lokhalo ndilakuti ndi chipinda chiti chomwe muyenera kukweza kaye.
