Ndezvipi zvakanakira LED kuratidza kupenya?Senzira yekushambadza, ma LED anoratidza masikirini anowanzo kuoneka muhupenyu hwedu, uye kudiwa kweruzivo rwekuchengetedza chiziviso chine chekuita ne LED kuratidza skrini kwawedzerawo.Ngatikurukurei nzira yekuziva kupenya kweiyo LED kuratidza.
Chekutanga pane zvese, ngatinzwisise kuti chii kupenya kweiyo LED kuratidza:
Kupenya kwe LED light-emitting chubhu kunoreva kusimba kwechiedza chinoburitswa nemuviri unopenya, unonzi light intensity, unoratidzwa muMCD.Kupenya kunopenya kwechiratidzo che LED indekisi yakazara, iyo inoreva iyo yakazara indekisi yeiyo yakazara luminous flux (luminous flux) yeese ma LED modules pachiyero cheyuniti uye kupenya kune imwe chinhambwe.
LED inoratidzira kupenya: Mune yakapihwa gwara, iyo inopenya kusimba pane imwe unit nzvimbo.Iyo unit yekupenya ndeye cd/m2.
Kupenya kwakaenzana nenhamba ye LED pane imwe unit nzvimbo uye kupenya kwe LED pachayo.Kupenya kwe LED kwakanangana nedhiraivha yayo ikozvino, asi hupenyu hwayo hwakapesana nehupamhi hweyazvino, saka dhiraivha yazvino haigone kuwedzerwa zvakanyanya mukutsvaga kupenya.Panguva imwecheteyo density, kupenya kwechiratidzo che LED kunoenderana nezvinhu, kurongedza uye saizi ye LED chip inoshandiswa.Iyo chip yakakura, iyo inowedzera kupenya;ukuwo, kuderera kupenya.
Saka ndezvipi zvinodikanwa zvekupenya kweambient kupenya kwescreen?
Izvo zvinodikanwa zvekupenya zvakajairika ndezvizvi:
(1) Indoor LED kuratidza:> 800CD/M2
(2) Semi-indoor LED kuratidza: > 2000CD/M2
(3) Kunze kwe LED kuratidzwa (gara kumaodzanyemba uye kutarisana nechokuchamhembe): > 4000CD/M2
(4) Kunze kwe LED kuratidzwa (gara kuchamhembe uye kutarisana nechokumaodzanyemba): > 8000CD / M2
Hunhu hwe LED inopenya machubhu inotengeswa mumusika haina kuenzana, uye kupenya kwakawanda hakugone kuvimbiswa.Vatengi vanonyengerwa nechiitiko che shoddy.Vanhu vazhinji havakwanisi kusiyanisa kupenya kwe LED luminous tubes.Naizvozvo, vatengesi vanoti kupenya kwakafanana nekupenya.Uye zvakaoma kuzvisiyanisa nemeso asina kupfeka, saka ungazviziva sei?
1. Nzira yekuziva sei kupenya kwe LED kuratidza
1. Ita 3V DC magetsi emagetsi ari nyore kubatanidza kune chiedza-emitting diode uri wega.Zvakanakisa kushandisa bhatiri kuigadzira.Iwe unogona kushandisa maviri mabhatani mabhatiri, woaisa mudiki epurasitiki chubhu uye kuburitsa maprobes maviri seakanaka uye asina kunaka anobuda.Iyo muswe inopera inogadzirwa zvakananga kuita switch ine shrapnel.Kana iri kushandiswa, iyo yakanaka uye yakaipa probes inoenderana neiyo yakanaka uye isina kunaka kubatanidzwa kwechiedza-emitting diode.Papini isina kunaka, dzvanya uye ubate switch kumagumo, uye iyo inopenya chubhu inoburitsa mwenje.
2. Chechipiri, batanidza photoresistor uye digitaalinen multimeter kuumba nyore chiedza metering mudziyo.Tungamira photoresistor newaya mbiri dzakatetepa uye uzvibatanidze zvakananga kune mapeni maviri edhijitari multimeter.Iyo multimeter inoiswa panzvimbo ye20K (zvichienderana nephotoresistor, Edza kuita kuti kuverenga kuve kwakarurama sezvinobvira).Ziva kuti iyo yakayerwa kukosha ndiyo chaiyo yekupikisa kukosha kweiyo photoresistor.Naizvozvo, kupenya kwechiedza, kudiki kukosha.
3. Tora LED light-emitting diode uye shandisa iri pamusoro 3V yakananga ikozvino kuivhenekera.Musoro unobudisa chiedza wakatarisana uye uri pedyo nepamusoro pephotosensitive pamusoro peiyo yakabatana photoresistor.Panguva ino, multimeter inoverenga kusiyanisa kupenya kwe LED.
2. Kupenya kwerusarura nhanho inoreva kupenya kwechifananidzo chinogona kusiyaniswa neziso remunhu kubva pane dema kusvika kune jena.
Iyo grey level ye LED kuratidza skrini yakakwirira kwazvo, iyo inogona kusvika 256 kana kunyange 1024. Zvisinei, nekuda kwekunzwa kushoma kwemaziso evanhu kupenya, aya mazinga egrey haagoni kunyatsozivikanwa.Mune mamwe mazwi, zvinogoneka kuti akawanda ari pedyo mazinga egrey scale maziso evanhu anotaridzika zvakafanana.Uyezve, mano okusiyanisa maziso anosiyana pamunhu nemunhu.Kune ma LED ekuratidzira masikirini, iyo yakakwira mwero wekuzivikanwa kweziso remunhu, zviri nani, nekuti mufananidzo wakaratidzwa ndewekuti vanhu vaone mushure mezvose.Kuwedzera kupenya kwemazinga iro ziso remunhu rinogona kusiyanisa, hombe nzvimbo yeruvara yeratidziro ye LED, uye yakakura mukana wekuratidza akapfuma mavara.Iyo yekupenya yekusarura nhanho inogona kuedzwa neakakosha software.Kazhinji, iyo skrini yekuratidzira inogona kusvika padanho remakumi maviri kana kupfuura, kunyangwe iri nhanho yakanaka.
3. Zvinodiwa pakupenya uye kona yekuona:
Kupenya kwemukati we LED kuratidzwa kunofanirwa kunge kuri pamusoro pe800cd/m2, uye kupenya kwekunze-yakazara-ruvara kuratidza kunofanira kunge kuri pamusoro pe1500cd/m2 kuve nechokwadi chekushanda kwakajairika kwechiratidziro che LED, zvikasadaro mufananidzo unoratidzwa hauzove wakajeka nekuti kupenya kwakaderera.Kupenya kunonyanya kutsanangurwa nemhando ye LED inofa.Saizi yekona yekutarisa inotarisisa vateereri veiyo LED kuratidza, saka yakakura zvirinani.Iyo kona yekuona inonyanya kutsanangurwa neiyo die package.
