Chikonzero nei iyo LED Mwenje Source Module Ichiita seisina Kugadzikana

Iko kushanduka kwemhando yemwenje ye LED bead VF haina kutariswa, zvichikonzera kuderera kwemwenje, uye kunyange mutengo wemutoro we LED light source module mune isina kugadzikana LED light source module. Iyo inowanzo kuumbwa akati wandei LED tambo ye LEDs. quantity. LED's VF inoshanduka nekuchinja kwekushisa. Kazhinji, panguva inogara iripo, VF inodzikira pakupisa kwepamusoro, uye VF inova yakakwira pakudzikira kwakadzika. Nokudaro, kushanda kwemagetsi emagetsi emwenje e LED pakupisa kwepamusoro kunoenderana neVOL, uye mwenje we LED wekutakura mhepo inoshandiswa pamhepo yakadzika inoenderana neVOH. Pakusarudza dhiraivha ye LED, mutyairi anobuditsa voltage renji yakakura kupfuura VOL VOH. Kana mutengo we LED light source module kune yakakura kubuda voltage yakaderera pane VOH, kushivirira kwerambi pakudzika kwakadzika kunogona kusasvika kune chaiyo simba. Kana iyo yakasarudzwa LED drive kune yakaderera voltage yakakwira kupfuura VOL, dhiraivha inogona kufambiswa nekupisa kwakanyanya pakupisa kwakanyanya. Kubuda kunodarika chiyero chekushanda, basa racho harina kugadzikana, marambi achapenya, nezvimwe. Asi mutengo wakadzama uye nekutarisa kwakanaka, haugone kutevedzera neupofu huwandu hweiyo LED driver's Ultra-wide kubuda voltage renji: nekuti mutyairi voltage inongori mune imwe nhanho, dhiraivha inoshanda ndiyo yakanyanya kunaka. Mushure mekupfuura chiyero, kushanda nesimba uye simba chinhu (PF) kuchaderera. Panguva imwecheteyo, dhizaini yekubuda kwevoltage renji yemutyairi yakawandisa, izvo zvinozoita kuti mari iwedzere uye kushanda zvakanaka hakugone kugadziridzwa. Kana iyo chiyero chesimba uye kudzikisa zvinodiwa zvikasatariswa, iro rezita simba reiyo LED drive inoreva iyo data yakayerwa neyakayerwa nharaunda uye yakayerwa voltage. Tichifunga kuti vatengi vakasiyana vachange vaine maapplication akasiyana, vatengesi vazhinji ve LED drive vanopa magetsi ekudzikisa curve pane yavo yezvigadzirwa zvechigadzirwa (yakajairwa mutoro VS ambient tembiricha inodonha curve uye mutoro VS yekupinda voltage yekudzikisa curve)). Iyo dzvuku curve inoratidza kuti kana mutengo we LED light source module waiswa 120VAC, simba rekudzikisa curve ine ambient tembiricha inoshanduka. Kana ambient tembiricha yakadzikira kupfuura 50 C, mutyairi anobvumira 100 yakazara mitoro. Kana tembiricha yepakati yakakwira kusvika 70 C, mutyairi anogona chete kuderedza mutoro kusvika 60%. Kana ambient tembiricha yachinja pakati pe50-70 C, dhiraivha redhiraivha rine tembiricha ine tembiricha ine tembiricha Kusimuka uye kuderera kwemutsara. Iyo yebhuruu curve inoratidza kuti kana mutyairi we LED apinda 230VAC kana 277VAC, mutoro wayo une simba rekudzikisa curve nekuchinja kwe tembiricha ye ambient. Iyo yebhuruu curve inoreva kuti kana mutyairi we LED ari 55 C, inobuda simba rekudzikisira curve nekuchinja kwemagetsi ekuisa anochinja. Kana magetsi ekuisa ari 140VAC, mutoro wemutyairi unobvumira 100 mitoro yakazara, uye sezvo magetsi ekuisa anoderedzwa; kana simba rekubuda richiramba risina kuchinjwa, iyo yekuisa ikozvino ichakwira, zvichikonzera kuwedzera kwekurasikirwa kwekupedzisira kwekupinza, kushanda kunoderera, kutonhora kwechigadzirwa kunokwira, nzvimbo yekushisa yega yega inogona kuitika. Mitemo yakawandisa ingatokonzera kuti michina ikundikane. Naizvozvo, kana magetsi ekuisa ari pasi pe140VAC, iyo inobuda mutoro wemutyairi inodikanwa kudzikiswa nemagetsi ekuisa uye kuderera kwemutsara. Mushure mekunzwisisa iyo yepamusoro yekudzikisa curve uye zvinoenderana nezvinodiwa, kana uchisarudza mutengo we LED light source module, iwe unofanirwa kunyatso funga uye kusarudza zvinoenderana neiyo chaiyo tembiricha yemamiriro ekunze uye ekuisa voltage mamiriro, uye wosiya zvakakodzera kuti usiye kudzikiswa kwekudzikisira. kuderedzwa kwemari yekuderedza.
