Ibipimo ngenderwaho by'igishushanyo mbonera cy'amatara yo mu muhanda ya LED

Bitandukanye n'amatara asanzwe yo ku muhanda,Amatara ya LED ku muhandakoresha amashanyarazi ya DC afite voltage nkeya. Izi nyungu zidasanzwe zitanga imikorere myiza, umutekano, kuzigama ingufu, kubungabunga ibidukikije, kuramba igihe kirekire, igihe cyo gusubiza vuba, hamwe n'amabara menshi, bigatuma bikoreshwa mu mihanda myinshi.

Igishushanyo mbonera cy'urumuri rw'amatara yo ku muhanda rwa LED gifite ibi bikurikira:

Ikintu cy'ingenzi cyane mu matara ya LED ni urumuri rwayo rutanga urumuri rw'icyerekezo. Amatara ya LED y'amashanyarazi hafi ya yose afite utugarura-rumuri, kandi imikorere y'utwo tugarura-rumuri iri hejuru cyane kurusha utw'utugarura-rumuri tw'itara. Byongeye kandi, isuzuma ry'imikorere y'urumuri rwa LED rikubiyemo imikorere myiza y'utugarura-rumuri twayo. Amatara ya LED y'umuhanda agomba kongera urumuri rwayo rw'icyerekezo, akareba ko buri LED iri mu cyuma iyobora urumuri kuri buri gace k'umuhanda umurikiwe. Hanyuma akagarura-rumuri k'icyuma gatanga umucyo w'inyongera kugira ngo hagerwe ku gukwirakwiza neza urumuri muri rusange. Mu yandi magambo, kugira ngo amatara yo ku muhanda yuzuze ibisabwa mu gupima no guhuza nk'uko bisabwa na CJJ45-2006, CIE31, na CIE115, agomba gushyiramo sisitemu yo gukwirakwiza urumuri rw'icyiciro bitatu. Amatara ya LED afite utugarura-rumuri n'inguni zo gutanga urumuri zitanga umucyo mwiza cyane. Mu cyuma gitanga urumuri, kunoza aho ashyirwa n'icyerekezo cy'urumuri rwa buri LED hashingiwe ku burebure bw'icyuma n'ubugari bw'umuhanda bituma habaho gukwirakwiza neza urumuri rw'inyongera. Akagarura-rumuri muri ubwo bwoko bw'urumuri kakora gusa nk'igikoresho cy'inyongera cyo gukwirakwiza urumuri rwa gatatu, kagatuma habaho urumuri rumwe mu muhanda.

Mu miterere nyayo y'ibikoresho by'amatara yo ku muhanda, igishushanyo mbonera cy'icyerekezo cya buri LED gishobora gushyirwaho, buri LED ifatanye n'igikoresho hakoreshejwe umupira. Iyo igikoresho gikoreshejwe ku burebure butandukanye n'ubugari butandukanye bw'imirasire, umupira ushobora guhindurwa kugira ngo ugere ku cyerekezo cyifuzwa kuri buri LED.

Sisitemu y'amashanyarazi ikoreshwa mu matara yo mu muhanda ya LED nayo itandukanye n'iy'amatara asanzwe. Amatara ya LED akeneye umushoferi udasanzwe uhoraho, ari na ngombwa kugira ngo akore neza. Uburyo bworoshye bwo guhinduranya amashanyarazi akenshi bwangiza ibice bya LED. Kwita ku mutekano wa LED zipakiye neza nabyo ni ikintu cy'ingenzi gishingirwaho mu gusuzuma amatara yo mu muhanda ya LED. Imiyoboro ya LED isaba umushoferi uhoraho. Kubera ko ingufu z'amashanyarazi zihuza amatara ya LED zihinduka gato cyane mu gihe cyo gukora imbere, kugumana umushoferi uhoraho wa LED by'ukuri bitanga imbaraga zihoraho zo gutanga.

Kugira ngo uruziga rw'umushoferi wa LED rugaragaze imiterere y'umuvuduko uhoraho, impedance y'imbere y'umuvuduko wayo, ireberwa ku mpera y'umushoferi, igomba kuba iri hejuru. Mu gihe cyo gukora, umuvuduko w'umuzigo nawo unyura muri iyi mpedance y'imbere y'umuvuduko. Niba uruziga rw'umushoferi rugizwe na step-down, rectifier-filtered, hanyuma DC constant current source circuit, cyangwa amashanyarazi akoreshwa muri rusange hamwe na resistor circuit, ingufu nyinshi zikoreshwa zizakoreshwa. Kubwibyo, nubwo ubwo bwoko bubiri bwa driver circuits bwujuje ibisabwa kugira ngo power output ihoraho, imikorere yabwo ntishobora kuba iri hejuru. Igisubizo gikwiye cyo gushushanya ni ugukoresha active electronic switching circuit cyangwa high-frequency current kugira ngo utware LED. Ubu buryo bubiri bushobora kwemeza ko driver circuit igumana imiterere myiza y'umuvuduko uhoraho mu gihe ikomeza kugira imikorere myiza yo guhindura.

Kuva ku bushakashatsi n'iterambere n'igishushanyo mbonera kugeza ku gutanga ibicuruzwa byarangiye,Amatara ya LED ya TIANXIANG ku muhandakugenzura imikorere y'urumuri, urumuri, uburinganire n'umutekano mu ruhererekane rwose, guhuza neza n'ibikenewe mu matara mu bihe bitandukanye nko mu mihanda yo mu mijyi, imihanda y'abaturage, na pariki z'inganda, gutanga ubufasha bwizewe ku mutekano w'ingendo za nijoro n'amatara arengera ibidukikije.
