Nzira yekusarudza iyo chaiyo LED mwenje sosi yepasi mwenje?
Nekukura kuri kuda kwekuchengetedza simba uye kuchengetedza kwezvakatipoteredza, tiri kuwedzera kushandisa marambi e LED mukugadzira mwenje wepasi. Musika we LED parizvino musanganiswa wehove nedhiragoni, yakanaka uye yakaipa. Vagadziri vakasiyana-siyana nemabhizinesi vari kushanda nesimba kusimudzira zvigadzirwa zvavo. Panyaya yemhirizhonga iyi, maonero edu zviri nani kumurega atumire bvunzo pane kuteerera.
Eurborn Co., Ltd ichatanga kusarudzwa kwe LED ye muvhu chiedza kunosanganisira kuonekwa, kupisa kupisa, kugovera chiedza, kupenya, kuiswa, nezvimwewo. Nhasi, hatingatauri pamusoro pemiganhu yemarambi nemarambi, kungotaura pamusoro pechiedza chechiedza. . Iwe unonyatsoziva here nzira yekusarudza yakanaka LED mwenje sosi? Iwo makuru ma paramita emwenje sosi ndeaya: ikozvino, simba, inopenya flux, inopenya attenuation, yakareruka ruvara uye ruvara kupa. Chinangwa chedu nhasi ndechekutaura pamusoro pezvinhu zviviri zvekupedzisira, kutanga kutaura muchidimbu nezvezvinhu zvina zvekutanga.
Chokutanga pane zvose, tinowanzoti: "Ndinoda watts mangani echiedza?" Iyi tsika ndeyekuenderera mberi nechiedza chekare chekare. Kare ikako, iyo mwenje sosi yaingova neakawanda akatarwa wattages, zvakanyanya iwe unogona chete kusarudza pakati peaya mawattages, haugone kuigadzirisa zvakasununguka, uye iyo yazvino LED nhasi, magetsi emagetsi achinja zvishoma, simba rinoshandurwa nekukurumidza! Kana iyo yakafanana mwenje sosi yemwenje yepasi ichifambiswa neyakakura ikozvino, simba rinokwira kumusoro, asi rinokonzera kuderera kwechiedza mukubudirira uye kuwedzera mukuora kwechiedza. Ndapota ona mufananidzo uri pasi apa
Kazhinji kutaura, redundancy = tsvina. Asi inochengetedza kushanda ikozvino kwe LED. Kana dhiraivha iripo inosvika pakakwirira inotenderwa chiyero pasi pemamiriro ezvinhu, ichidzikisa dhiraivha iripo ne1/3, iyo yakabairwa inopenya inoyerera ishoma, asi mabhenefiti akakura:
Chiedza attenuation yakaderera zvikuru;
Urefu hwehupenyu hunowedzerwa zvakanyanya;
Kuvimbika kwakagadziridzwa kwakakura;
Kushandiswa kwesimba kwepamusoro;
Naizvozvo, kune yakanaka LED mwenje sosi yepasi, yekutyaira ikozvino inofanira kushandisa inosvika 70% yehupamhi yakayerwa ikozvino.
Muchiitiko ichi, mugadziri anofanira kukumbira zvakananga kupenya kunopenya. Kana iri iyo wattage yekushandisa, inofanirwa kusarudzwa nemugadziri. Izvi ndezvekusimudzira vagadziri kuti vatevedze kushanda nesimba uye kugadzikana, pachinzvimbo chekupira kushanda nesimba uye hupenyu nekusimudza wattage yemwenje sosi upofu.
Izvo zvataurwa pamusoro apa zvinosanganisira aya ma parameter: ikozvino, simba, luminous flux, uye luminous attenuation. Pane hukama hwepedyo pakati pavo, uye iwe unofanirwa kuchenjerera kwavari mukushandisa: Ndeipi iyo yaunoda chaizvo?
Chiedza chemavara
Munguva yezvinyorwa zvechinyakare zvemwenje, kana zvasvika pakudziya kwemavara, munhu wese ane hanya chete nezve "yellow mwenje uye chena mwenje", kwete dambudziko rekutsauka kwemavara. Zvakadaro, tembiricha yeruvara rwechinyakare mwenje sosi ingori rudzi irworwo, ingosarudza imwe, uye kazhinji haizonyanya kukanganisa. Munguva ye LED, takaona kuti ruvara rwechiedza chepasi chiedza chine zvakawanda uye chero rudzi. Kunyange bhechi rimwe chete remarambi rinogona kutsauka kune zvakawanda zvechienzi, misiyano yakawanda.
Wese munhu anoti LED yakanaka, inochengetedza simba uye ine hushamwari. Asi kune makambani mazhinji chaizvo anoita kuti ma LED aora! Inotevera ipurojekiti yakakura inotumirwa neshamwari ine chinangwa Kushandiswa kwehupenyu chaihwo kwemhando yakakurumbira yemumba yemarambi eLED nemarambi, tarisa uku kugovera kwechiedza, uku kuenderana kwetembiricha yeruvara, iyi mwenje webhuruu usina kusimba….
Tichifunga nezvemhirizhonga iyi, fekitori yekuvhenekesa ye LED yakavimbiswa kune vatengi: "Marambi edu ane kutsauswa kwekushisa kwemavara mukati me ± 150K!" Kana kambani ichiita kusarudzwa kwechigadzirwa, zvinotsanangurwa zvinoratidza: "Zvinoda kutsauka kwekushisa kwemavara emarambi mabheji ari mukati me ± 150K"
Iyi 150K inobva pakuguma kwekutora zvinyorwa zvechinyakare: "Kutsauswa kwekushisa kwemavara mukati me ± 150K, izvo zvakaoma kuti ziso remunhu rione." Vanotenda kuti kana tembiricha yemavara iri "mukati me ± 150K" izvo zvisingawirirane zvinogona kudzivirirwa. Muchokwadi, hazvisi nyore kudaro.
Semuenzaniso, mukamuri yekuchembera yeiyi fekitari, ndakaona mapoka maviri emabhara emwenje ane mavara echiedza akasiyana. Rimwe boka rakanga riri jena rinodziya, uye rimwe boka rakanga rakarerekera divi rimwe chete. Sezvinoratidzwa mumufananidzo, tinogona kuwana mutsauko pakati pemabhawa maviri emwenje. Imwe yakatsvuka uye imwe yakasvibira. Zvinoenderana nezvakataurwa pamusoro apa, kunyangwe maziso emunhu anogona kutaura zvakasiyana, hongu musiyano wetembiricha yemavara unofanirwa kunge wakakwira kupfuura 150K.
Sezvaunogona kutaura, maviri masosi emwenje anotaridzika zvakasiyana zvachose kune ziso remunhu ane "yakabatana ruvara tembiricha" musiyano we20K chete!
Haisi mhedziso yekuti "kutsauka kwemavara ekushisa kuri mukati me ± 150K, zvakaoma kuti ziso remunhu rione" rakaipa? Usanetseke, ndapota nditenderei nditsanangure zvishoma nezvishoma: Rega nditaure nezve pfungwa mbiri dzetembiricha yeruvara vs (CT) yakabatana tembiricha yemavara (CCT). Isu tinowanzo taura nezve "tembiricha yeruvara" yemwenje sosi kune muchiedza chepasi, asi kutaura zvazviri, isu tinowanzo tora iyo "yakabatana ruvara tembiricha" mushumo webvunzo. Tsanangudzo yeaya ma paramita maviri mu "Architectural Lighting Design Standard GB50034-2013"
Rudzi Tembiricha
Kana chromaticity yemwenje sosi yakafanana neyemuviri mutema pane imwe tembiricha, tembiricha yemuviri mutema ndiyo tembiricha yeruvara rwechiedza. Iyo inozivikanwawo sechroma. Iyo unit ndeye K.
