LED Power Drive Knowledge

Kupisa kupisa, simba rekutyaira, uye mwenje sosi ndiwo anonyanya kukosha echigadzirwa chemwenje che LED. Kunyange zvazvo kupisa kwekushisa kunonyanya kukosha, kupisa kwekushisa kunobata zvakananga hupenyu hwechigadzirwa chekuvhenekera, asi chiedza chechiedza ndicho chikamu chikuru chechigadzirwa chose. Hupenyu hwesimba rekutyaira pachayo uye kugadzikana kwezvinobuda uye voltage zvine simba guru pahupenyu hwese hwechigadzirwa.

Iyo LED mutyairi simba rekupa zvakare chigadzirwa chekuwedzera. Hunhu hwesimba pamusika parizvino hauna kuenzana. Imwe ruzivo nezve LED mutyairi simba inopiwa pazasi.　

LED drive magetsi maficha

　　(1) Kuvimbika kwakakwirira

Kunyanya semagetsi ekufambisa emagetsi emagetsi e LED, anoiswa panzvimbo yakakwirira, kugadzirisa hakuiti, uye mari yekugadzirisa zvakare yakakura.

(2) Kubudirira kwepamusoro

Ma LED zvinhu zvinochengetedza simba, uye kushanda kwemagetsi ekutyaira kwakakwira. Zvinonyanya kukosha kubvisa kupisa kubva kune magetsi akaiswa mukugadzirisa. Simba remagetsi rine hukuru hwekushanda, simba rayo rekushandisa idiki, uye kupisa kunogadzirwa mumwenje kuduku, izvo zvinoderedza kukwira kwekushisa kwemwenje. Zvinobatsira kunonoka kuora kwechiedza che LEDs.

(3) High simba chinhu

Chinhu chemagetsi ndicho chinodiwa negridi. Kazhinji, hapana zviratidzo zvinosungirwa zvemidziyo yemagetsi iri pasi pe70 watts. Kunyange zvazvo simba remutengi ane simba rimwechete rine simba rakaderera rine simba shoma pane girasi remagetsi, huwandu hwekuvhenekera hunoshandiswa usiku hwakakura, uye mutoro wakafanana wakanyanyisa, izvo zvichakonzera kusvibiswa kwakakomba kune grid simba. Kune 30 watts kusvika 40 watts ye LED mutyairi simba, zvinonzi munguva pfupi iri kutevera, panogona kunge kune zvimwe zviratidzo zvesimba zvinhu.

(4) Nzira yekutyaira

Kune mhando mbiri dzetraffic: imwe inogara iri voltage sosi yeakawanda anogara aripo masosi masosi, uye imwe neimwe inogara iripo sosi inopa simba kune yega yega LED zvakasiyana. Nenzira iyi, kusanganiswa kunoshanduka, uye zvikanganiso zvose zve LED hazvikanganisi basa remamwe ma LED, asi mari ichave yakakwirira zvishoma. Imwe yacho yakananga nguva dzose magetsi emagetsi, inova nzira yekutyaira inotorwa ne "Zhongke Huibao". Iwo ma LED anoshanda munhevedzano kana mukuwirirana. Zvakanakira kuti mutengo wakaderera, asi kuchinjika kwakashata, uye zvakafanira kugadzirisa kumwe kutadza kwe LED pasina kukanganisa kushanda kwemamwe ma LED. Aya mafomu maviri anogara kwenguva yakati. Multi-channel inogara iripo yekuburitsa magetsi emagetsi modhi ichave iri nani maererano nemutengo uye kuita. Zvichida ndiyo nzira huru mune ramangwana.

(5) Kuwedzera kudzivirira

Kugona kwema LED kutsungirira masurges kune hurombo, kunyanya kupokana nereverse voltage kugona. Zvakakoshawo kusimbisa kudzivirira munzvimbo iyi. Mamwe marambi e LED anoiswa kunze, akadai semwenje yemugwagwa we LED. Nekuda kwekutanga kwegidhi mutoro uye kuiswa kwekurova kwemheni, mavhisi akasiyana achapindirwa kubva kune grid system, uye kumwe kuvhiya kunokonzeresa kukuvara kwe LED. Iyo LED mutyairi magetsi anofanirwa kuve nekugona kudzvanya kupindira kwekuvhiya uye kudzivirira iyo LED kubva mukukuvara.

(6) Basa rekudzivirira

Kuwedzera kune yakajairwa kuchengetedza basa, iyo magetsi inogonesa kuwedzera iyo tembiricha ye LED yakaipa mhinduro mune inogara iripo inobuda kudzivirira tembiricha ye LED kubva pakunyanya; inofanirwa kusangana nezvinodiwa zvekuchengetedza mirau uye electromagnetic kuenderana.
