LED Ikinyabiziga kimurika

Kubijyanye n'amatara y'imodoka, muri rusange twita ku mubare wa lumens n'imbaraga. Mubisanzwe bizera ko hejuru "agaciro ka lumen", niko amatara yaka! Ariko kumatara ya LED, ntushobora kuvuga gusa agaciro ka lumen. Ibyo bita lumen nigice cyumubiri gisobanura urumuri rwa luminous, rusobanurwa na physics nka buji (cd, candela, luminous unit unit, ihwanye nuburemere bwurumuri rwa buji isanzwe), muburyo bukomeye (ubumwe kuzenguruka hamwe na radiyo ya metero 1). Ku muzenguruko, inguni igereranwa na cone spherical ihuye n'ikamba rya sheferi ya metero kare 1, ihuye n'inguni yo hagati yo hagati (hafi 65 °), itanga urumuri rwinshi rusohoka.
Kugirango turusheho gushishoza, tuzakoresha itara rya LED kugirango dukore igerageza ryoroshye. Itara ryegereye ubuzima kandi rishobora kwerekana cyane ikibazo.

 

LED yerekana urumuri

Duhereye ku mashusho ane yavuzwe haruguru, turashobora kubona ko itara rimwe rifite isoko imwe yumucyo, ariko urumuri rurahagarikwa, nuko rero hari itandukaniro rinini cyane, ryerekana ko urumuri rwamatara rutajyanye gusa nubucyo bwa isoko yumucyo ubwayo, ariko kandi ntishobora gutandukana nicyuma. Isano. Kubwibyo, urumuri rwamatara ntirushobora gusuzumwa gusa na lumens. Kumatara, dukwiye gukoresha "imbaraga zumucyo" zifatika kugirango ducire urubanza,
Ubwinshi bwurumuri bivuga imbaraga zumucyo ugaragara wakiriwe kuri buri gice, byitwa kumurika, naho igice ni Lux (Lux cyangwa Lx). Ijambo ryumubiri ryakoreshejwe kwerekana ubukana bwurumuri nubunini bwurumuri hejuru yubuso bwikintu.

Uburyo bwo gupima kumurika nabwo buroroshye kandi bworoshye. Nyuma yo gupakira, irashobora gupimwa gusa na illuminometero. Lumens irashobora kwerekana gusa amakuru yumucyo ubwayo mbere yimodoka. Itara nyuma yimodoka rigomba kuba ryibanze kandi rikagabanywa na ecran. Niba intumbero idakwiye, niba urumuri rudashobora gucika burundu, nubwo "lumen" iri hejuru gute.
 

(Imbonerahamwe yigihugu yerekana urumuri rwerekana amatara yimodoka)
Amatara yimodoka nayo akeneye gusohora urumuri binyuze mumucyo hanyuma ugahagarikwa nigikombe cyerekana. Itandukaniro n’itara ni uko urumuri rwumucyo wimodoka rutazenguruka nkitara. Ibisabwa byamatara yimodoka birakomeye kandi biragoye, kubwumutekano wo gutwara no Urebye umutekano wabanyamaguru, hashyizweho urwego rwumucyo nurwego rwurumuri, kandi iki gipimo cyitwa "ubwoko bwurumuri".

"Ubwoko bwurumuri" (urumuri ruto) rwamatara rugomba kuba hasi ibumoso naho hejuru iburyo, kuko uruhande rwibumoso rwimodoka zo murugo ni umwanya wumushoferi. Mu rwego rwo kwirinda amatara atangaje no guteza imbere umutekano wo gutwara iyo modoka zombi zihuye mugihe cyo gutwara nijoro. Umucyo uri iburyo ni muremure. Ku mushoferi wimodoka yibumoso-ibumoso, uruhande rwiburyo rwikinyabiziga rufite umurongo mubi ugereranije kandi ukeneye umurima mugari wo kureba. Gerageza gushobora kumurikira kaburimbo, ihuriro nibindi bihe byumuhanda hamwe nubuso bunini iburyo, niba bishoboka. Fata ingamba mbere yigihe. (Niba ari imodoka yo gutwara iburyo, ishusho yumucyo ihabanye)
Ibyiza by'amatara ya LED
1. LED ibicuruzwa byoroheje ni voltage ntoya itangira, kandi ibintu byumutekano biri hejuru;
2. LED ibicuruzwa byoroheje bitangira ako kanya, bikaba bihuye nibyifuzo byimodoka zabantu;
3. Kuzigama ingufu no kurengera ibidukikije, hamwe nibyiza bigaragara mugutezimbere ibinyabiziga bishya byingufu mugihe kizaza;
4. Hamwe nogukomeza gutezimbere no kunoza urwego rwo hejuru rwamashanyarazi ya LED yamashanyarazi yinganda, inyungu zihenze zamatara ya LED zizakomeza kugaragara.
5. Plastike yumucyo wa LED irakomeye cyane, irakwiriye cyane kubijyanye nigihe kizaza cyo gukoresha.
