Arahina Tohu i runga i te ara iahiko

Interesting ki te kite pēhea te mīharo hangarau tere kē. E toru tekau tau ki muri, ko matou tino makona ki te hikohiko, whakamahia nei te, i te motokā tika, tetahi wahi whakararuraru, me iti-tere, whare tano kahore whakahoutanga. Ko te tangata kia whakaturia e te tonu te tutava no te tahi mea atu tino, a inaianei tata rohe katoa o te ora, ko te kaupapa ki te ao hou, tamau. Pa, whakaatu ano hoki tenei tukanga me ngā pūnaha rama. Na, haere mai matou ki ngā pūrere Semiconductor atu matatau ki te whakakapi rama aano - LED.

emitting karaihe

tīmata te hītori o te whakamahi o Semiconductors pakeke te whakamahi i rama E-momo. AS Popov, nei whakaaro ko te ihi o te reo irirangi, rapu i te tikanga o te pūrere Semiconductor ohie, te aroaro o ngaru irirangi. Kua Popov ngōhiko tuatahi (pūoko) kua hanga e i te maramara Semiconductor whakaritea i roto i te taata tei mau, me te puna whakapā o te Tungsten oka rino ranei. okioki ana tēnei whakapā kei i runga i te rohe Semiconductor, a ki runga ki te wāhi whakapā rānei kia kitea ki te tino mārama transceiver tohu.

kitea te kaha o etahi tioata ki emit marama i te nāianei i muri mai, i te tupono noa, engari e kore e te wa tuatahi i whakamahia i roto i te mahi. Na, Heoi, LEDs e whānui e whakamahia ana i roto i te taputapu motuhake, me i roto i te ora ia rā.

He aha te mea he LED, te ara titiro ai i runga i te tūtohi?

momo arahina huaina Semiconductor huānga he singularity o te karaihe ki te emit marama i raro i te mana o te therethrough e haere nāianei hiko. E kore te mea tenei pānga i Semiconductors katoa, engari anake te hunga i nei i roto i te tukanga o te tauhono o irahiko me rua te tuku o te pūngao puta i roto i te whānuitanga whatu. Arahina rite te ngōhiko tikanga, he PN-komititanga me haere nāianei i roto i te ahunga kotahi anake.

He āhuatanga o LED rite te pūrere emitting marama ko e te tukua ai quanta tika marama. titore ana tēnei i te reira i rama aano, e puta tōrino whakawera tuatahi ki te tetahi pāmahana, kōnakonako rama ranei ki te pānga ionization. parekura Energy i roto i te te p marama-emitting whiwhi.

Te hanganga, i roto i te tïpako arahina e pani ki te terminals karaihe mo te hononga ki te taiawhio hiko me te whare, i te mea te wā kotahi te pūnaha whatu. ti'araa arahina i roto i te kaupapa kua he tetahi kīanga whakairoiro, i runga i te poari hiko denoted ia he whakawaehere motuhake.

He aha te arahina, me pehea kitea tenei i roto i tona whakaaturanga i runga i te tūtohi?

E faatae mai te marama LED, ko tona whakaaro tenei. A i roto i te schematic e mārama e te pere e rua e haere mai ana i te huānga. Kua riro te whakamahi o te pūrere rawa whanui:

• whakaatu rerekē. Hei whakaoho whakaurua o ngā aratau o ngā pūrere hiko mā te whakamahi i ngā huānga motuhake. he rōpū o ngā pūrere e whakamahia ana i roto i te whakaatu mamati, te wahi ia wāhanga arahina nui te tūranga o tau pukapuka ranei. Tohu arahina i runga i te ara iahiko ngā i roto i te rōpū, e kore e waiho motuhake mo ia, ka whakaaturia te rōpū katoa kei roto i te puka o te tohu ki te peka, me te taua o hoapā.
• Hoki rama noho, tūmatanui, me te ahumahi.
• Hei wāhanga o te mata mō te pāpāho waho, me te ki te waihanga kuputuhi panuku.
• Ko te optocouplers. kō atu hoahoa ti'araa arahina i roto i tenei take e ki te huānga image photodetector.
• pūnaha muka-whatu. Here, mahi nga LED rite radiators o te ngaru whatu modulated.
• Hei huluhulu te mata karaihe wai.
• Hoahoa me te ahumahi whakangahau.

Āhuatanga o te drawings tirohia ki te Semiconductor

paerewa Hangarau me ture faatere i te ti'araa o te arahina i runga i te ara iahiko. GOST 2.702-2011 whakatakoto:

• Whakaatu LED me ētahi atu huānga taiawhio i te tikanga o kai tuhi, ranei i roto i te puka-hiko. I roto i tenei take, te kōwhiringa whakamutunga ko ki te whai i te taumira o te iti rawa 300dpi ka whakauru i te tif toronga kōnae bmp ranei.
• Ko te LED Ko te mahi schematic rite te ngōhiko tikanga kopakia ana i roto i te porohita. Runga ake te wahi matau o runga o te paenga e whakaritea e rua pere whakarara, whakawhānui i te mema turanga i te koki ki te maha tika.
• LED Tata tohu tona waehere ārepa tonu.
• No mea pehea te arahina i runga i te ara iahiko, me te wehenga tawhiti i roto i tetahi aronga ranei tetahi ranei i te koki, e noho tonu te aronga o te pere.
• Ko te putanga e haere mai ana i te tapatoru i roto i te hoahoa tohu te pitoake (+) me te rārangi poutū - he pitoiho (-).
• kia whai i te LED i runga i te ara iahiko ona ake tau rangatū. Ko te taua haere i mahue ki matau, runga ki raro.

Arahina - wehenga ti'araa

ti'araa arahina i runga i te tūtohi hanga reira ngāwari ki te whakatau i te wehenga tawhiti, engari kia whakatau i te reira i te tūemi hou hokona, e hiahia ana koe ki te titiro i tona whakapā. kāpeka pitoake pai te tikanga he roa nui atu te pitoiho.

Ki te eke i te arahina i runga i te poari, me ia, mo mea katoa take, kua kahore huānga tohu, ka taea te whakaritea te wehenga tawhiti o te Semiconductor, he titiro i tona tinana. Mai i te taha o te pitoiho (kāpeka tōraro) i runga i te tinana i te kakari āhua flat. Ano, ka arahina kite te momo marae mārama tona roto. Ōritetanga o te kapu, kei ai te te maramara Semiconductor, kua he hononga tika ki te pitoiho.

I roto i te take te wahi he e taea ai ki te whakatau i te wehenga tawhiti o nga tikanga i runga ake, engari i reira ko te aroaro o te multimeter hiko, ka taea e koe te whakamahi i te reira. Tangohia ngōhiko noa o te wehenga tawhiti mōhiotia hoatu tonu ki te pūrere mahi, me te hono atu ki te Semiconductor. Rokiroki i te wehenga tawhiti ka fakahoko nāianei te ngōhiko. Arahina hono ki te schupam ruri. Me whakarite e tataki reira nāianei, mōhio wehenga tawhiti.

Ko te arahina i runga i te poari

A, no te radiomontazhniki te whakaminenga poari ara iahiko tāngia ake pūnaha me te whakatakotoranga o te rārangi o ngā huānga. E ai ki tenei rārangi o tohu tīpakongia tohu i te momo o ngā tau tūemi me tūranga ki runga ki te ara iahiko. He ao paerewa tohu i runga i te poari, e e whakamahia nuitia i roto i te taputapu kawemai.

Ko te ti'araa o te poari arahina i roto i te puka o whakapakoko whakairoiro, whakawaehere mau me tau. Ko te whakaaturanga tuatahi i roto i nga Semiconductors neke matua, tohu nga pukapuka te momo o te pūrere, me te tau - ko te tau rangatū ki te kaupapa, me te i roto i te rārangi.

He momotuhi kauwhata mō te papa iahiko arahina he ōrite ki tona whakapakoko i roto i te tuhi, engari kāore pea e whai i te paenga a tawhio noa te icon ngōhiko. Ko te whakawaehere whakamana reta whakapaipai mau - arahina (kawemai kaupapa) me HL (kāinga). Ko te maha mai i muri i te pukapuka ranei te raro. Te kore te tau e taea ki te whakatau i te tawhā o te Semiconductor e kore e te poari tohu he okotahi onge.

tohu LED

pū arahina i runga i te kaupapa (tohu) He te mōhiohio katoa e pā ana ki te āhuatanga o te pūrere ngā Semiconductor. Tohu kei te rota tonu o pūāhua, na e kore e te hoatu ai ki runga ki te whare, me te mata i roto i te ara iahiko i runga i te tākai ranei e kore e soldered huānga. He LEDs i roto i te rïpene he whanga i te coils, e mau nga tohu tohu. whakaata whakawaehere Pūāhua:

• He raupapa o ngā hua.
• Ko te tae o te marama arahina. He ma, matomato, whero, puru, karaka, kōwhai te p marama-emitting Modern.
• Ko te kounga o te rere tae. Hei tauira, te raiti arahina i roto i te whare ranei i runga i te huarahi, pūrere whakaatu, rama, hoki tāhū, image.
• momo o te arotahi. He mea marama-haapurararaa me te radiation arotahi ki te arotahi domed, mārama, me te puatakore.
• putanga Light.
• Consumption o te kaha hiko.
• waehere tāututanga o te kaiwhakanao. He kahore kawenga mahi.
• tohu rāhui. waiho ratou Manufacturers mo te whakarereke taea o te huānga.

Kahore he paerewa motuhake mo te tapanga o LED, na ia kaihanga kua ona ake whakawaehere. Kia mahara e kore te mea e ahei, engari e kore te mea rawa nui te kamupene nui o tenei hua i runga i te mākete. I roto ia ratou e taua kamupene rite Philips, Cree ko Samsung.

mutunga

I tua atu ki LED tikanga ki te titi, i reira SMD-LED ki Pads. He iti i roto i te rahi ratou. He māmā, me te nuinga o te wā whāiti ki tohu te pitoruatanga reta ti'araa o LED o taua momo i roto i te Scheme ōrite ki arahina-āhuatanga, engari te poari.
