12V 3mm Green LED Hanga-i roto i te parenga DC

12 wae LED ki 12V 3mm Na roto i-poka LED Green parare LED

He E rua ara ki te whakaputa i te 12V ngōhiko emitting marama, te tetahi tuatahi ko ki mua-waea i te parenga ki te mata arahina. E te tikanga, i ia wa oti matou te hanga o arahina Rama, e ti'a ia tatou ki te Weld te iahiko paku (e pā ana ki 1mm) ki te huha arahina kia taea te hanga i te reira tino tenei LED mahi pūmau i roto i 12V ngaohiko tiketike. I te tahi atu te ringa, ka taea e tatou te tāpiri i te hanga i roto i te parenga iahiko ki te arahina, i te mea tahi ki te maramara arahina. Tenei 304LGD52D7L12V12 Ua he hanga i roto i te parenga iahiko i roto i te mōkihi aifaito matomato, ara ko tenei 3mm matomato i roto i-poka arahina, te resisitor tonu nui iti ki te kia tākai roto. I roto i tenei ara, tatou e kore e taea e ai kite i te iahiko iti rānei i o arotahi aifaito. Ko te mahi i te reira mahi pai mo te Green Throguh-rua arahina roto. Ki te hiahia koe i LED matomato etahi 12V 3mm mo koutou kaupapa, tika ite noa ki te whakapā mai me te whiwhi taipitopito atu e pā ana ki reira ~

Ahu o 3mm Green i roto i-poka arahina:

Tawhā Electrical:

* Motopaika nako rama;

Taipitopito Hua:

99.99% waea te viivii koura;

Hiriwa whakakikoruatia anga arahina;

Tītipi parani rongonui;

Epoxy kounga High;

Hokohoko te ahunga whakamua o roto i-poka arahina:

Whakatauritea ki SMD arahina, ka kia atu faingataa i roto i-rua arahina production. E te tikanga ka tangohia reira atu te ahunga whakamua production me te wā whakaputa:

Tuatahi o te katoa, he aha matou ki te faaineine i te maramara arahina (ka taua rite SMD LED production tenei); Tuarua, ka hiahia tatou ki te hoatu i te kongakonga arahina ki te anga arahina, a ka ka hiahia tatou te waea koura parakore ki te hono i te pitoiho me pitoake o anga arahina. He haere mai rerekē, hoki SMD LED production, e ti'a ia tatou ki te hoatu i te epoxy ki arahina anga, me te tatari noa maroke i te reira i te oumu. Heoi, hoki LED Rama, Me matou ki te wero epoxy ki te pokepokea ai o arotahi me te hoatu i nga mea katoa ki te oumu mo te iti rawa 8 haora maroke noa ratou. I muri i taua, e ti'a ia tatou ki te Color ratou i te oumu, me te tiki i te arahina atu o pokepokea ai. Na reira e hiahia ana matou ki te tapahi i te titi o arahina kia e taea e ratou ngāwari ki te whakamātautau.

I te pae hopea, ka matou te arahina. I roto i te tikanga ki te kia te kounga me te kākahu rite pai rite hiahiatia. Me hoki tatou ki te hoatu katoa te arahina ki te mīhini wehenga, me ratou e ka e matou te arahina ki taua rāpihi.
