Niki UL940 V0 kumurongo wa LED?

Laboratoire zandika (UL) zashyizeho urwego rwa UL940 V0 rwo gucana kugira ngo rwemeze ko ibikoresho - muri uru rugero, urumuri rwa LED - byujuje ubuziranenge bw’umuriro n’ibipimo by’umuriro. Inzira ya LED ifite icyemezo cya UL940 V0 yakorewe ibizamini byinshi kugirango irebe ko idashobora kurwanya umuriro kandi ntizakwirakwiza umuriro. Hamwe niki cyemezo, imirongo yumucyo LED yemerewe gukurikiza amategeko akomeye yumutekano wumuriro kandi igakoreshwa mugihe umutekano wumuriro aricyo kintu cyambere.
Amatara yamatara agomba kuba yujuje ibyangombwa byokongoka umuriro hamwe n’ibisabwa kurwanya umuriro washyizweho na Laboratoire ya Underwriters (UL) kugira ngo yemeze nka UL94 V0. Ubushobozi bwibikoresho bwo guhangana n’umuriro no guhagarika ikwirakwizwa ry’umuriro nicyo kintu nyamukuru cyibisabwa. Ibisabwa byingenzi kumurongo wamatara nibi bikurikira:
Kuzimya: Iyo inkomoko yo gutwikwa ikuweho, ibikoresho bigomba kuzimya byonyine mugihe cyagenwe.
Ikwirakwizwa rya flame ntoya: Ibintu ntibigomba gutwikwa kurenza uko biri cyangwa gukwirakwira vuba kurenza uko byakagombye.
Ibitonyanga bibujijwe: Ibintu ntibigomba kurekura ibitonyanga byaka cyangwa ibice bishobora gukwirakwiza umuriro vuba.
Ibisabwa byo kwipimisha: Ukurikije igipimo cya UL94, umurongo wamatara ugomba gutsinda ibizamini bikubiyemo ibizamini byahagaritswe kandi bitambitse.
Iyo itara ryujuje ibyangombwa bisabwa, byerekana ko rifite imbaraga zo kurwanya umuriro no gukwirakwizwa kwaka umuriro, bigatuma umutekano mukoreshwa muburyo butandukanye - cyane cyane aho umutekano wumuriro ari ngombwa.

Nta kintu na kimwe gishobora kuvugwa ko kitagira umuriro rwose, nubwo itara ryambuye ryabonye igipimo cya UL94 V0 cyerekana umuriro mwinshi cyerekana urwego rwo hejuru rwo kurwanya umuriro no gukwirakwizwa n’umuriro.N'ubwo ibikoresho bifite uburinzi bwa UL94 V0 bigamije kugabanya cyane hasi ibyago byumuriro, ibikoresho birashobora gufata umuriro mubihe bikomeye nko guhura nubushyuhe bwo hejuru mugihe kinini cyangwa umuriro utaziguye. Kubwibyo, tutitaye ku gipimo cy’ibikoresho byo kurwanya umuriro, ni ngombwa gukomeza kwitonda no kubahiriza amategeko agenga imikoreshereze y’umutekano. Ubwanyuma, kwemeza neza kandi neza gukoresha amatara ya strip cyangwa ibindi bikoresho by'amashanyarazi, ni ngombwa kumvira inama zakozwe n’ibanze amategeko y’umutekano w’umuriro.
Twandikireniba ushaka kumenya amakuru menshi yerekeye amatara ya LED arimoCOB CSP, Neon flex, umurongo mwinshi wa voltage hamwe no gukaraba.
