Ikizamini cy'amatara yo ku muhanda ya LED

Itara rya LED rikunze kuba kure yacu, iyo urumuri rupfuye, tugomba gutwara ibikoresho n'ibikoresho byose bikenewe, kandi bisaba tekiniki kugira ngo risanwe. Bifata igihe kandi ikiguzi cyo kuryitaho kiraremereye. Bityo rero, isuzuma ni ingenzi. Gupima itara rya LED ririmo isuzuma ry'uburinzi bw'amazi cyangwa uburinzi bw'ingress (IP), isuzuma ry'ubushyuhe, isuzuma ry'uburinzi bw'ingaruka (IK), isuzuma ry'ubusaza, n'ibindi.

Ikizamini cyo kurinda kwinjira (IP)

Igena niba urumuri ruzarinda ibice bikora amazi, umukungugu, cyangwa ikintu gikomeye kwinjira, bigatuma ibicuruzwa biguma mu mutekano kandi bigakomeza igihe kirekire. Isuzuma rya IP ritanga isuzuma rishobora gusubiramo kugira ngo rigereranye uburinzi bw'aho byashyizwe. Isuzuma rya IP risobanura rite? Umubare wa mbere mu isuzuma rya IP usobanura urwego rw'uburinzi ku kintu gikomeye kuva ku kuboko kugera ku mukungugu, naho umubare wa kabiri mu isuzuma rya IP usobanura urwego rw'uburinzi ku mazi meza kuva kuri mm 1 y'imvura kugeza ku mazi y'agateganyo kugeza kuri metero 1.

Dufate urugero rwa IP65, “6” bivuze ko nta mukungugu winjiramo, “5” bivuze ko birinzwe n’amazi aturuka mu nguni iyo ari yo yose. Ikizamini cya IP65 gisaba igitutu cya 30kPa ku ntera ya metero 3, ingano y’amazi ikaba litiro 12.5 ku munota, igihe cy’ikizamini ni umunota 1 kuri metero kare nibura iminota 3. Ku matara menshi yo hanze, IP65 ni nziza.

Hari uturere tugwa imvura nyinshi dukenera IP66, "6" bivuze ko turinzwe n'amazi menshi n'inyanja nyinshi. Ikizamini cya IP66 gisaba umuvuduko wa 100kPa ku ntera ya metero 3, ingano y'amazi ikaba litiro 100 ku munota, igihe cy'ikizamini kikaba umunota 1 kuri metero kare nibura iminota 3.

Ikizamini cyo kurinda ingaruka (IK)

Amahame ngenderwaho y’isuzuma rya IK: IEC 62262 igaragaza uburyo imvange zigomba gupimwa kugira ngo zimenyekane ku isuzuma rya IK, ibi bikaba ari urwego rw’uburinzi imvange zitangwa ku ngaruka zo hanze.

IEC 60598-1 (IEC 60529) igaragaza uburyo bwo gupima bukoreshwa mu gushyira mu byiciro no gupima urwego rw'uburinzi urugomero rutanga ku bintu bikomeye bitandukanye binini kuva ku ntoki no ku ntoki kugeza ku mukungugu muto ndetse no kurinda amazi kwinjira mu bitonyanga bigwa bikagera ku muvuduko mwinshi w'amazi.

IEC 60598-2-3 ni Igipimo Mpuzamahanga cy’Amatara ku Mihanda no ku Mihanda.

IK points zisobanurwa nka IKXX, aho "XX" ari umubare kuva kuri 00 kugeza kuri 10 ugaragaza urwego rw'uburinzi butangwa n'ibizingo by'amashanyarazi (harimo n'ibimuri) ku ngaruka zo hanze. Igipimo cya IK points kigaragaza ubushobozi bw'ibizingo bwo kurwanya urwego rw'ingufu z'ingaruka zipimwe muri joules (J). IEC 62262 igaragaza uburyo ibizingo bigomba gushyirwaho kugira ngo bipimwe, imiterere y'ikirere ikenewe, ingano n'ikwirakwizwa ry'ingaruka z'ibizamini, hamwe n'inyundo y'ingaruka igomba gukoreshwa kuri buri rwego rw'isuzuma rya IK.
