Muri iki gihe LED yabaye igice kitagerwaho mubuzima bwacu. Uyu munsi, nzaguha intangiriro ngufi kubitekerezo, ibiranga, no gutondekanya.

Igitekerezo cya LED

LED (Umucyo Utanga Diode) nigikoresho gikomeye cya semiconductor gihindura amashanyarazi kumucyo. Umutima wa LED ni chip ya semiconductor, hamwe numutwe umwe ufatanye na scafold, impera imwe ikaba ari electrode itari nziza, naho iyindi ihujwe nimpera nziza yo gutanga amashanyarazi, kuburyo chip yose iba ifunze muri an epoxy resin.

Chip ya semiconductor igizwe n'ibice bibiri, kimwe muri byo ni p-ubwoko bwa p-semiconductor, aho imyobo yiganje, naho ikindi kikaba n-ubwoko bwa n-semiconductor, kuri electron ziganje. Ariko iyo semiconductor zombi zahujwe, habaho “pn ihuza” hagati yabo. Iyo umuyoboro ushyizwe kuri chip unyuze mu nsinga, electron zisunikwa kuri p-karere, aho zongera guhurira nu mwobo kandi zigatanga ingufu muburyo bwa fotone, nuburyo LED zaka. Kandi uburebure bwumucyo, ibara ryumucyo, bigenwa nibikoresho bigize ihuriro rya PN.

Ibiranga LED

Ibiranga LED byerekana ko aribwo buryo bwiza bwo gutanga urumuri rwo gusimbuza urumuri gakondo, rufite intera nini yo gusaba.

• Umubumbe muto

LED mubusanzwe ni chip nto cyane ikubiye muri epoxy resin, nuko rero ari nto cyane kandi yoroheje.

-Koresha ingufu nke

LED ikoresha ingufu ni nkeya cyane, mubisanzwe, LED ikora ni 2-3.6V.
Imikorere ikora ni 0.02-0.03A.
Nukuvuga ko itwara amashanyarazi atarenze 0.1W.

• Ubuzima Burebure

Hamwe numuyoboro ukwiye hamwe na voltage, LED irashobora kugira ubuzima bwa serivisi bwamasaha 100.000.

• Umucyo mwinshi n'ubushyuhe buke

• Kurengera Ibidukikije

LED ikozwe mubikoresho bidafite uburozi, bitandukanye n'amatara ya fluorescent, arimo mercure kandi atera umwanda. Birashobora kandi gukoreshwa neza.

• Birakomeye kandi biramba

LED iba yuzuye neza muri epoxy resin, ikaba ikomeye kuruta itara ryaka ndetse nigituba cya fluorescent.Nta bice byacitse imbere mumatara, bigatuma LED idashobora kurimburwa.

Itondekanya rya LED

1, Ukurikije umuyoboro utanga urumuriibaraingingo

Ukurikije urumuri rutanga urumuri rwumucyo utanga urumuri, rushobora kugabanywamo umutuku, orange, icyatsi (nicyatsi kibisi cyumuhondo, icyatsi kibisi nicyatsi kibisi), ubururu nibindi.
Mubyongeyeho, LED zimwe zirimo chip y'amabara abiri cyangwa atatu.
Ukurikije urumuri rusohora diode ivanze cyangwa itavanze nabatatanye, ibara cyangwa ibara, amabara atandukanye yavuzwe haruguru ya LED nayo ashobora kugabanywamo ibara ryeruye, ridafite ibara ryeruye, amabara atatanye kandi akwirakwiza ibara ryubwoko bune.
Gukwirakwiza diode itanga urumuri n'umucyo - gusohora diode birashobora gukoreshwa nk'itara ryerekana.

2. Ukurikije ibiranga urumurihejuruy'umucyo usohora umuyoboro

Ukurikije ibiranga urumuri rusohora urumuri rusohora urumuri, rushobora kugabanywa mu itara ryizengurutse, itara rya kare, itara ry'urukiramende, itara ryo mu maso risohora umuyoboro, umuyoboro wo ku ruhande hamwe na tike ya micro kugirango ushyire hejuru, nibindi.
Itara ry'umuzingi rigabanyijemo Φ2mm, Φ4.4mm, Φ5mm, Φ8mm, Φ10mm na Φ20mm, n'ibindi.
Ubusanzwe abanyamahanga bandika di3mm itanga urumuri nka T-1, φ5mm nka T-1 (3/4), naφ4.4mm nka T-1 (1/4).

3.Kurikijeimiterereya diode itanga urumuri

Ukurikije imiterere ya LED, hariho epoxy enapsulation, ibyuma fatizo epoxy encapsulation, ceramic base epoxy encapsulation hamwe nikirahure.

4.Kurikijeubukana bwa luminous hamwe nibikorwa bigezweho

Ukurikije ubukana bwa luminous na current current bigabanijwemo urumuri rusanzwe LED (ubukana bwa luminous 100mCD);
Imbaraga zumucyo hagati ya 10 na 100mCD zitwa umucyo mwinshi urumuri rutanga urumuri.
Imiyoboro ikora ya LED rusange kuva kuri mA icumi kugeza kuri mA mirongo, mugihe amashanyarazi akora ya LED ntoya iri munsi ya 2mA (umucyo ni nkuw'umuyoboro usanzwe utanga urumuri).
Usibye uburyo bwo gutondekanya hejuru, hariho nuburyo bwo gutondekanya ibikoresho bya chip nibikorwa.

Ted: ingingo ikurikira nayo ivuga kuri LED. Niki? Nyamuneka komeza ukurikirane.
