Banyere LED - Nkebi nke mbụ

LED_bulbs

N'oge a LED aghọwo akụkụ na-enweghị ike ịnweta nke ndụ anyị. Taa, a ga m enye gị okwu mmeghe nkenke maka echiche, njirimara na nhazi.

Echiche nke LED

Igwe ọkụ (Light Emitting Diode) bụ ngwaọrụ semiconductor steeti siri ike nke na-agbanwe ọkụ eletrik ozugbo na ọkụ. Obi nke LED bụ mgbawa semiconductor, nke nwere otu njedebe na-ejikọta ya na scaffold, otu njedebe ya bụ electrode na-adịghị mma, na njedebe nke ọzọ jikọtara ya na njedebe dị mma nke ike ọkụ, nke mere na a na-ejikọta mgbawa dum na otu. epoxy resin.

Ihe mgbawa nke semiconductor nwere akụkụ abụọ, otu n'ime ha bụ p-ụdị semiconductor, nke oghere na-achịkwa, nke ọzọ bụ semiconductor n-ụdị, nke electrons na-achịkwa. Ma mgbe ejikọtara semiconductors abụọ ahụ, "pn junction" na-etolite n'etiti ha. Mgbe a na-etinye ihe dị ugbu a na mgbawa site na waya, a na-agbanye electrons na p-mpaghara, ebe ha na-ejikọta na oghere ahụ ma na-emepụta ike n'ụdị photon, nke bụ otú LEDs na-enwu. Na ogologo oge nke ìhè, agba nke ìhè, na-ekpebi ihe na-emepụta njikọ PN.

Njirimara nke LED

Njirimara dị n'ime nke LED na-ekpebi na ọ bụ isi iyi kachasị mma iji dochie isi iyi ọkụ ọdịnala, ọ nwere ọtụtụ ngwa.

  • Obere Olu

Igwe ọkụ ọkụ bụ obere mgbawa etinyere na resin epoxy, yabụ na ọ dị obere ma dịkwa ọkụ.

-Obere ike oriri

Oriri ike LED dị obere, n'ozuzu n'ikwu okwu, voltaji arụ ọrụ LED bụ 2-3.6V.
Ọrụ ugbu a bụ 0.02-0.03A.
Ya bụ, ọ dịghị ihe karịrị 0.1W ọkụ eletrik.

  • Ogologo ndụ ije ozi

Site na ugbu a na voltaji ziri ezi, LED nwere ike ịnwe ndụ ọrụ ruo awa 100,000.

  • Elu ihie na obere okpomọkụ
  • Nchekwa gburugburu ebe obibi

A na-eji ihe ndị na-adịghị egbu egbu eme LEDs, n'adịghị ka oriọna fluorescent, nke nwere mercury na-ebute mmetọ. Enwere ike megharịa ha.

  • Ike na Inogide

LEDs na-ejupụta n'ụzọ zuru ezu na epoxy resin, nke dị ike karịa ma ọkụ ọkụ na fluorescent tubes. Enwekwara akụkụ ndị na-adịghị mma n'ime oriọna ahụ, nke na-eme ka ọkụ ndị ahụ ghara imebi.

Nhazi nke LED

1, Dị ka ọkụ emitting tubeagbaisi

Dị ka ìhè na-agbapụta agba nke tube na-egbuke egbuke, enwere ike kewaa ya na-acha uhie uhie, oroma, akwụkwọ ndụ akwụkwọ ndụ (na odo odo, akwụkwọ ndụ akwụkwọ ndụ na-acha ọcha na akwụkwọ ndụ akwụkwọ ndụ dị ọcha), acha anụnụ anụnụ na ihe ndị ọzọ.
Na mgbakwunye, ụfọdụ LED nwere ibe nke agba abụọ ma ọ bụ atọ.
Dị ka ìhè emitting diode agwakọta ma ọ bụ na-adịghị agwakọta na-agbasasị, acha ma ọ bụ colorless, ndị dị n'elu dị iche iche na agba nke LED nwekwara ike kewara n'ime acha transperent, colorless transperent, acha agbasasị na-enweghị agba nkesa nke anọ ụdị.
Enwere ike iji diodes na-ekpochapụ ọkụ na ọkụ - diode na-ekupụta dị ka oriọna na-egosi.

2.Dịka njirimara nke luminouselunke ìhè emitting tube

Dị ka àgwà nke ìhè emitting elu nke ìhè emitting tube, ọ nwere ike kewaa gburugburu oriọna, square oriọna, akụkụ anọ oriọna, ihu ìhè emitting tube, akụkụ tube na micro tube maka elu echichi, wdg.
A na-ekewa oriọna okirikiri ahụ na Φ2mm, Φ4.4mm, Φ5mm, Φ8mm, Φ10mm na Φ20mm, wdg.
Ndị mba ọzọ na-edekọkarị diode Φ3mm na-enye ọkụ dị ka T-1, φ5mm dị ka T-1 (3/4), naφ4.4mm dị ka T-1 (1/4).

3. Dị ka ndịnhazinke ìhè-emitting diode

Dị ka ihe owuwu nke ikanam, e nwere niile epoxy encapsulation, metal base epoxy encapsulation, seramiiki base epoxy encapsulation na iko encapsulation.

4.Dịkaluminous ike na arụ ọrụ ugbu a

Dị ka luminous ike na-arụ ọrụ ugbu a na-ekewa n'ime nkịtị ihie ikanam (luminous ike 100mCD);
A na-akpọ ọkụ ọkụ dị n'etiti 10 na 100mCD diode nchapụta dị elu.
Igwe ọkụ na-arụ ọrụ nke LED n'ozuzu sitere na iri mA ruo ọtụtụ MA, ebe ọrụ ugbu a nke LED dị ala dị n'okpuru 2mA (nchapụta bụ otu ihe ahụ nke tube ọkụ nkịtị).
Na mgbakwunye na ụzọ nhazi ọkwa ndị a dị n'elu, enwekwara ụzọ nhazi ọkwa site na ihe mgbawa na site na ọrụ.

Ted: isiokwu na-esote bụkwa maka LED. Kedu ihe ọ bụ? Biko nọrọ na nche.:)
