7.1 Yanayin Aikace-aikace na Yau da Kullun

Wannan LED ya dace da:

• Hasken Cikin Motoci: Gunkin kayan aikin dashboard, hasken baya na maɓalli, ɗigon hasken yanayi na ciki.
• Hasken Waje na Motoci: Fitilun alamar gefe, fitilun tsakiyar tsayawa mai tsayi (CHMSL), alamun nuna juyi (ya danganta da ƙa'idodin gida da ƙarfin da ake buƙata).

Kusurwar kallonsa mai faɗi yana sa ya dace da aikace-aikace inda ake buƙatar ganin haske daga kusurwoyi masu yawa.

7.2 Tambayoyi da Amsoshi Game da Ƙira da Amfani

Tambaya: Menene ƙarfin lantarki na turawa da aka ba da shawarar?

Amsa: Ƙarfin lantarki na aiki na yau da kullun shine 20mA, yana ba da daidaitaccen ma'auni na haske da tsawon rayuwa. Matsakaicin matsakaici shine 50mA na ci gaba, amma aiki kusa da wannan iyaka yana buƙatar kulawar zafi a hankali kamar yadda aka nuna a cikin lankwasa rage ƙarfi.

Tambaya: Ta yaya zan tabbatar da daidaiton launi a cikin ƙirata?

Amsa: Ayyana rukunin tsawon zango mai rinjaye da ake buƙata (8588, 8891, ko 9194) lokacin yin oda. Amfani da LED daga rukunin samarwa ɗaya yana rage bambancin launi.

Tambaya: Shin resistor mai iyakancewa ya zama dole?

Amsa: Ee. LED ɗin na'urori ne masu turawa ta hanyar ƙarfin lantarki. Resistor na waje mai iyakancewa ko da'irar turawa mai ƙarfi na yau da kullun ya zama dole don hana guduwar zafi da lalata LED, musamman saboda bambancin ƙarfin lantarki na gaba (1.75V zuwa 2.75V).

Tambaya: Shin za a iya amfani da shi a aikace-aikacen da ba na motoci ba?

Amsa: Duk da cewa ya cancanci amfani da motoci, dogaronsa mai girma yana sa ya dace da sauran aikace-aikacen masana'antu masu tsauri, masu amfani, ko na alama inda ake buƙatar ƙarfin yanayi.

7.3 Nazarin Shari'ar Ƙira Mai Amfani

Yi la'akari da ƙirar fitilar nuna alama ta dashboard. Matakan ƙira zasu haɗa da: 1) Ƙayyade ƙarfin haske da ake buƙata bisa ga buƙatun gani na rana (zaɓar rukunin da ya dace, misali, AA ko AB). 2) Ƙirar da'irar turawa: Ƙididdigar ƙimar resistor na jeri don wadatar motoci na 12V, la'akari da rukunin ƙarfin lantarki na gaba na LED (misali, 2022 don ~2.1V) don cimma 20mA. Tsarin shine R = (V_wadatar- V_F) / I_F. 3) Binciken zafi: Tabbatar da cewa shimfidar PCB da yuwuwar zafin yanayi kusa da dashboard ba sa haifar da zafin wurin gyaɗa ya wuce matakin da ake buƙatar rage ƙarfi (duba lankwasa rage ƙarfi). 4) Aiwatar da kariya daga polarity mai juyawa akan PCB, saboda ba a tsara LED don aiki da ƙarfin lantarki mai juyawa ba.

8. Ka'idojin Fasaha da Mahallin Masana'antu

8.1 Ka'idar Aiki

Wannan LED tushen haske ne na semiconductor. Lokacin da aka yi amfani da ƙarfin lantarki na gaba wanda ya wuce bakin kofar sa, electrons suna sake haɗuwa da ramuka a cikin guntun semiconductor, suna sakin makamashi a cikin nau'in photons. Kayan musamman da ake amfani da su a yankin aiki na guntun suna ƙayyade tsawon zango (launi) na hasken da aka fitar, a wannan yanayin, rawa. Kunshin PLCC-2 ya haɗa da kofin mai nuna alama da ruwan tabarau na epoxy da aka ƙera don siffanta fitarwar haske da kuma cimma ƙayyadaddun kusurwar kallo na digiri 120.

8.2 Kwatance da Trends

Idan aka kwatanta da tsofaffin LED ɗin da ake amfani da su ta cikin rami, wannan na'urar PLCC-2 SMD tana ba da ƙaramin sawu, mafi dacewa don haɗawa ta atomatik, da ingantaccen aikin zafi saboda ƙirarta wanda ke ba da damar zafi ya watsa ta wurin gyaɗa. Trends a cikin hasken motoci yana zuwa ga ingantacciyar inganci (ƙarin lumens a kowace watt), ƙananan girman kunshi wanda ke ba da damar ƙira mai santsi, da ƙara haɗa kayan aikin sarrafa lantarki (misali, turawa LED) kai tsaye tare da tushen haske. Abubuwan kamar wannan, tare da cancantar AEC-Q102 da babban haske a cikin ƙaramin kunshi, sun yi daidai da waɗannan buƙatun masana'antu don ingantattun tsarin hasken motoci masu dogaro.
