Kukosha kwedhiraivha simba rekupa kune LED luminaires
Vamwe vagadziri vanowedzera purofiti kuitira kuti vaderedze mitengo nekushandisa madhiraivha asina kunaka. Panofanira kunge paine nyaya yekuchengetedzwa isina kuisirwa neichi chigadzirwa chakachengetedzeka chinoputika.
Mamwe mafekitari, kuitira kuderedza mutengo wezvigadzirwa, kushandiswa kwekusingaperi voltage drive LED, kwakaunzawo kugadzirwa kwemazhinji ega ega LED luminescence kupenya hakusi yunifomu, maLED haagone kushanda mune yakanaka mamiriro uye akatevedzana matambudziko.
Constant ikozvino sosi dhiraivha yakanaka LED yekutyaira modhi, kushandiswa kweanogara aripo sosi dhiraivha, haifanirwe kunge iri mune inobuda dunhu teedzero ikozvino muganho kuramba, LED ikozvino kuyerera haina kukanganiswa nekunze kwemagetsi emagetsi shanduko, ambient tembiricha shanduko, pamwe ne LED parameter discrete, kuitira kuti urambe uripo, ipa yakazara kutamba kune akasiyana akanakisa maitiro e LED.
Kushandisa LED inogara iripo magetsi emagetsi emagetsi emagetsi e LED, nekuti iyo ikozvino inoyerera kuburikidza ne LED inongoonekwa uye inodzorwa panguva yebasa rekupa magetsi, saka haufanirwe kunetseka nezvekuve nekuyerera kwazvino kuburikidza ne LED munguva yesimba. , uye haufanirwe kunetseka nezvekuremerwa kupfupi-kutenderera magetsi ekupa.
Kushandisa inogara iripo yedhiraivha modhi, inogona kudzivirira shanduko ye LED yakanaka voltage uye kukonzera shanduko yazvino, nepo inogara iripo ichiita kuti kupenya kwe LED kugadzikane, asi zvakare kugonesa LED luminaire fekitori kuti iite kugadzirwa kwemazhinji kuti ive nechokwadi chekuenderana kwechigadzirwa, saka vagadziri vazhinji vakaziva zvizere kukosha kwekutyaira magetsi ekufambisa, vazhinji vanogadzira marambi e LED vakasiya inogara voltage modhi, uye vanosarudza mutengo wakakwira zvishoma unogara uripo nzira yekutyaira LED luminaires.
Vamwe vagadziri vanonetseka kuti simba rekushandisa dhiraivha bhodhi electrolyte capacitor richakanganisa hupenyu hwemagetsi, iko kusanzwisisana, semuenzaniso, kana ukasarudza madhigirii 105, hupenyu hwemaawa 8000 ekushisa kwakanyanya kwe electrolyte capacitor, maererano neiyo iripo electrolyte capacitor. mararamiro ekufungidzira nzira "yose kuderedzwa kwe1 0 madhigirii, kaviri hupenyu", zvino ine hupenyu hwekushanda hwe16,000 maawa munzvimbo ye95-degree, hupenyu hwekushanda hwe32,000 maawa munzvimbo ye85-degree, uye hupenyu hwekushanda Maawa 64,000 munzvimbo ye75-degree. Kana tembiricha yekushanda chaiyo yakadzikira, hupenyu hunenge hwakareba! Kubva pakuona uku, chero bedzi kusarudzwa kwepamusoro-soro electrolyte capacitors pahupenyu hwemagetsi ekufambisa magetsi hakukanganisi!
Pane zvakare poindi yakakodzera ye LED luminaire mabhizinesi cherechedzo: nekuti LED mukuita basa ichaburitsa huwandu hukuru hwekupisa, kuitira kuti tembiricha yepakati ikwire nekukurumidza, iyo yakakwirira iyo LED simba, iyo yakakura kupisa mhedzisiro. Kuwedzera kwekushisa kwe LED chip kuchaita kuti kuchinja kwekushanda kwemagetsi ekubudisa chiedza uye electro-optical conversion kunyatsoita attenuation, zvakakomba kana kunyange kukundikana, maererano nemiedzo yekuedza inoratidza kuti: LED yayo pachayo kupisa kwe5 degrees Celsius, kuyerera kwechiedza. yakaderedzwa ne3%, saka zvivheneko zve LED zvinofanirwa kutarisisa kune iyo LED sosi yemwenje sosi pachayo inotonhorera basa, kana zvichikwanisika kuwedzera nzvimbo inotonhorera yemwenje we LED sosi pachayo, nepazvinobvira kuderedza tembiricha yekushanda ye LED. pachayo, kana mamiriro ezvinhu achibvumira, simba rekupa chikamu rakaparadzaniswa kubva kune chiedza chitubu chikamu, Hazvidikanwi kutevera hukuru diki uye kufuratira tembiricha yekushandisa yemarambi uye magetsi.
