I ēnei rā, kua noho te rama LED hei wāhanga o tō tātou ao e kore e taea te uru atu. I tēnei rā, ka hoatu e au he kupu whakataki poto ki te ariā, ngā āhuatanga, me te whakarōpūtanga.

Te Ariā o te LED

Ko te LED (Light Emitting Diode) he taputapu haurua-ā-roto totoka e huri tika ana i te hiko ki te Mārama. Ko te ngākau o te LED he maramara haurua-ā-roto, ko tetahi pito e piri ana ki te tūāpapa, ko tetahi pito he irahiko kino, ā, ko tetahi pito e hono ana ki te pito pai o te pūtake hiko, kia kapi katoa ai te maramara i roto i te kapia epoxy.

E rua ngā wāhanga o te maramara haurua-irahiko, ko tētahi he haurua-irahiko momo-p, e nui ana ngā kōhao i roto, ko tētahi he haurua-irahiko momo-n, e nui ana ngā irahiko i runga. Engari ina honoa ngā haurua-irahiko e rua, ka puta he "hononga pn" i waenganui i a rāua. Ina tukuna he ia ki te maramara mā te waea, ka panaia ngā irahiko ki te rohe-p, ka hono anō ki te kōhao, ka tukuna te pūngao i roto i te āhua o ngā photon, koinei te āhua o te kanapa o ngā LED. Ā, ko te roanga ngaru o te mārama, te tae o te mārama, ka whakatauhia e te rauemi e hanga ana i te hononga PN.

Ngā Āhuatanga o te LED

Ko ngā āhuatanga ā-roto o te rama LED e whakatau ana koinei te puna mārama tino pai hei whakakapi i te puna mārama tuku iho, ā, he whānuitia hoki ōna whakamahinga.

• Rōrahi Iti

Ko te rama LED he maramara iti rawa kua whakakiia ki te kapia epoxy, nō reira he tino iti, he tino māmā hoki.

-Te Whakamahinga Mana Iti

He iti rawa te whakamahinga hiko o te LED, ko te ngaohiko whakahaere o te LED he 2-3.6V i te nuinga o te wā.
Ko te iahiko mahi he 0.02-0.03A.
Ara, kāore e neke atu i te 0.1W te hiko e pau ana.

• Te Ora Ratonga Roa

Mā te iahiko me te ngaohiko tika, ka taea e ngā LED te roa o te mahi tae atu ki te 100,000 hāora.

• Te Kanapa Nui me te Wera Iti

• Te Tiaki Taiao

He mea hanga ngā rama LED ki ngā rauemi kore-paitini, he rerekē ki ngā rama fluorescent, kei roto nei te mercury, ā, ka puta te parahanga. Ka taea hoki te hangarua.

• Kaha, ā, pakari

Kua whakakīia katoatia ngā rama LED ki te kapia epoxy, he kaha ake i ngā pūangi rama me ngā ngongo hihi-ātaahua. Kāore hoki he wāhanga wetewete i roto i te rama, e kore ai e taea te whakangaro i ngā rama LED.

Te Whakarōpūtanga o te LED

1, E ai ki te ngongo e whakaputa ana i te māramataengā tohu

E ai ki te tae o te ngongo e whakaputa ana i te mārama, ka taea te wehewehe ki te whero, te karaka, te kakariki (me te kōwhai kakariki, te kakariki paerewa me te kakariki parakore), te kikorangi me ētahi atu.
Hei tāpiritanga, kei roto i ētahi rama LED he maramara o ngā tae e rua, e toru rānei.
E ai ki te whakaranu, te kore whakaranu rānei o ngā rama rama marara, tae, kore tae rānei, ka taea hoki te wehewehe i ngā tae LED rerekē ki ngā momo tae mārama, tae kore tae mārama, tae kore tae mārama, tae marara me te tae kore tae marara.
Ka taea te whakamahi i ngā taiorama tuku mārama me ngā taiorama tuku mārama hei rama tohu.

2. E ai ki ngā āhuatanga o te kanapamatao te ngongo e whakaputa ana i te māramatanga

E ai ki ngā āhuatanga o te mata e puta ai te mārama o te ngongo e puta ai te mārama, ka taea te wehewehe ki te rama porowhita, te rama tapawhā, te rama tapawhā, te ngongo mata, te ngongo taha me te ngongo moroiti mō te tāutanga mata, me ētahi atu.
Kua wehea te rama porowhita ki Φ2mm, Φ4.4mm, Φ5mm, Φ8mm, Φ10mm me Φ20mm, me ētahi atu.
Ko te tikanga, ka tuhia e te iwi ke te Φ3mm light-emitting diode hei T-1, φ5mm hei T-1 (3/4), meφ4.4mm hei T-1 (1/4).

3. E ai ki tehangangao ngā diode e whakaputa ana i te mārama

E ai ki te hanganga o te LED, kei reira ngā momo epoxy encapsulation katoa, ngā epoxy turanga whakarewa, ngā epoxy turanga uku me ngā epoxy turanga karāhe.

4. E ai kite kaha o te māramatanga me te iahiko mahi

E ai ki te kaha o te kanapa me te iahiko mahi, ka wehea te kanapa noa o te LED (kaha kanapa 100mCD);
Ko te kaha o te mārama i waenga i te 10 me te 100mCD ka kiia ko te diode emitting light-emitting wherikotanga teitei.
Ko te iahiko mahi o te rama LED whānui kei waenganui i te tekau mA ki te tekau mA, ko te iahiko mahi o te rama LED iti kei raro iho i te 2mA (he rite te kanapa ki te kanapa o te ngongo rama noa).
Haunga ngā tikanga whakarōpū o runga ake nei, kei reira anō ngā tikanga whakarōpū mā te rauemi maramara me te mahi.

Ted: Ko te tuhinga e whai ake nei mō te LED anō hoki. He aha tēnei? Kia mataara tonu mai.
