He aha te tukanga o te hanga rama riu LED?
He aha te tukanga whakaputa LED
He aha te tukanga hanga maramara LED?
Inaa he tino uaua te mahi angiangi epitaxial, i te whakaaturanga i muri i te angiangi epitaxial, ka timata ki te LED angiangi epitaxial mahi hiko i muri (P, N), katahi ka tiimata ki te whakamahi miihini laser mo te tapahi i te wafer epitaxial LED (i mua LED epitaxial angiangi te nuinga whakamahi taimana tapahi maripi), hanga ki te maramara, i nga waahi rereke i roto i te angiangi i runga i te tangohanga o nga tawhā whakamatautau e iwa.
- Te nuinga whakamatautau i te ngaohiko, te roangaru me te kanapa o nga angiangi ka taea te tutuki i nga tawhā paerewa tuku noa ka haere tonu ki te mahi ka whai ake. Mena karekau te whakamatautau iwa ira e tutuki i nga whakaritenga e tika ana, ka waiho nga angiangi ki te taha mo tetahi atu mahi.
2, angiangi tapahia ki maramara, % tirohanga tirohanga (VI/VC), me whakamahi e te kaiwhakahaere karukaropi whakanui 30 nga wa mo te tirohanga tirohanga.
3, ka whakamahi whakarōpū aunoa rite ki ngaohiko rerekē, roangaru, tawhā matapae wherikotanga o te maramara ki te kowhiringa aunoa, whakamātautau me te whakarōpūtanga. - Ka mutu, taki (VC) ka tapaina te maramara LED. Ko te waahi maramara me noho ki waenganui o te kiriata puru, me te nuinga o nga maramara kei runga i te kiriata puru, engari ko te maha o nga maramara mo ia kiriata puru kaua e iti iho i nga maramara, me te momo maramara, tau rota, me tuhi nga tatauranga inenga nui me te whakaahua hiko ki te tapanga e piri ana ki muri o te pepa waxy. The chips on the blue film will undergo the final visual inspection according to the same standards as the first visual inspection to ensure that the chips are neatly arranged and of good quality. This makes LED chips (collectively known as squares on the market at present).
In the process of LED chip production, the chip with some defects or electrode wear, sorted out, these are the loose crystals behind, at this time in the blue film there are some do not meet the normal shipping requirements of the chip, it will naturally become a side piece or hair, etc.
Talked about in different locations on the wafer extraction parameters testing, nine points do to do not conform to the requirements of the wafer for additional processing, these cannot be directly used to make the LED wafer square piece, also won’t do any sorting, sold directly to customers, which is currently on the market the LED wafer (but also have good things in your wafer, such as the party).
Nga rama haukura LED
Mai i te taenga mai o nga rama neon, after a hundred years of unfailing. It is a special low pressure cold cathode glow discharge electric light source, a he rereke mai i etahi atu penei i te rama rama, rama konutai pehanga teitei, rama halide whakarewa, rama mercury, incandescent lamp and other arc lamp. Neon lights are produced by a cold cathode glow discharge under a high voltage field of inert gas filled in a glass tube. The color of the neon lamp is determined by the spectral characteristics of the inert gas. Fluorescent neon lights are filled with argon and mercury, ko nga rama neon e tuku ana i te rama kikorangi me te kowhai. These two types of neon lights are generated by excited radiation from the atoms of the working gas in the tube. Compared with other electric light sources, Ko nga rama haukura nga ahuatanga e whai ake nei:
Tuatahi, kakama teitei
Ko nga rama haukura e whakawhirinaki ana ki nga hiko i nga pito e rua o te rama i roto i te waahi ngaohiko teitei ka noho te hau i roto i te ngongo., he rereke mai i te puna marama noa me tahu waea tungsten ki te teitei teitei ki te marama, ka puta te nui o te hiko hiko i te ahua o te wera wera ka pau, no reira, me te nui o te kaha hiko, He teitei ake te kanapa o te neon.
Rua, he iti te pāmahana, karekau te whakamahi i te aukati i te rangi
Rama haukura na te ahua o te katode makariri, kei raro te pāmahana ngongo i te 60°C i te wa e mahi ana, no reira ka taea te whakanoho ki te hau tuwhera i te ra me te ua, i roto ranei i te tinana.
He iti te kohi hiko
I roto i te wa o te auaha hangarau tonu, kei te whakapai tonu te hangarau hanga o nga rama neon me te taumata hangarau o nga waahanga e pa ana. Ko te tono o nga hiko hou me nga huringa hiko kua tino whakahekehia te kaha o nga rama neon, mai 56 Watts ia mita rama ki 12 Watts ia mita rama.
E wha, ora roa
Nga rama haukura i te mahi tonu i raro i te ahua o te hiko tonu, ora ake i te 10,000 haora, he uaua tenei painga ki te whakatutuki i tetahi atu puna marama hiko.
Rima, hanga hangawari, kanorau tae
He mea hanga mai i nga ngongo karaihe ka taea te pupuhi me te piko ki tetahi ahua me te tino ngawari. Ma te kowhiri i nga momo ngongo me te whakakii ki nga momo hau koretake, ka taea e te haukura te whakaputa i te kara, rama maha-tae.
ono, hihiri, pānga pai, ohaoha me te mahi
Mata marama haukura e te ngongo marama tonu me te titonga ngongo matawai marama, ka taea te whakarite ki te peke karapa, āta matawai, huringa tae hanumi whitu karapa kara. Te ngongo matawai ma te whakaurunga ki te mana whakahaere matawai maramara rorohiko moroiti, ngongo matawai kia rite ki te marama o te papatono kua oti te whakarite, kua weto ranei, te hanga rerenga pikitia, ano he aniwaniwa i te rangi, rite te Milky Way, ano he ao moemoea, whakamihi, e kore e warewaretia. No reira, Ko te neon he momo panui me te iti ake o te haumi, pānga kaha me te whaipainga ohaoha
