9. Tambayoyin da ake yawan yi (Dangane da Sigogi na Fasaha)

9.1 Menene bambanci tsakanin Matsakaicin Tsawon Zango da Matsakaicin Tsawon Zango?

Matsakaicin Tsawon Zango (λ_P):Madaidaicin tsawon zango inda LED ke fitar da mafi yawan ikon gani (630nm na al'ada).Matsakaicin Tsawon Zango (λ_d):Madaidaicin tsawon zango guda ɗaya wanda ya fi dacewa da launin da idon ɗan adam ya gane (625nm na al'ada). λ_dana ƙididdige shi daga madaidaitan launi na CIE kuma ya fi dacewa don ƙayyadaddun launi.

9.2 Zan iya tuƙa wannan LED a 20mA akai-akai?

Ee, 20mA shine matsakaicin ƙimar ci gaba da halin yanzu na DC a yanayin yanayi na 25°C. Duk da haka, idan yanayin yanayi ya wuce 30°C, dole ne ku rage ƙimar halin yanzu bisa ga ƙayyadaddun adadin 0.27 mA/°C. Misali, a yanayin yanayi na 50°C, matsakaicin halin yanzu da aka yarda zai zama 20mA - (0.27mA/°C * (50°C-30°C)) = 14.6mA.

9.3 Me ya sa ake buƙatar resistor na jerin ko da tare da samar da ƙarfin lantarki mai dorewa?

Ƙarfin lantarki na gaba na LED ba ƙima ce mai ƙayyadaddun ƙima kamar diode Zener ba; yana da juzu'in samarwa kuma yana raguwa tare da haɓakar zafin jiki. Resistor na jerin yana aiki azaman mai sarrafa halin yanzu mai sauƙi, mai tsayi. Idan ba tare da shi ba, ƙaramin canji a cikin ƙarfin wutar lantarki ko LED V_F(saboda bambancin zafin jiki ko kwandon binne) na iya haifar da babban canji a cikin halin yanzu, yana shafar haske sosai kuma yana iya wuce matsakaicin ƙimar.

10. Misalin Aikace-aikace na Aiki

Yanayin:Ƙira alamar kunna wuta don na'urar da ke aiki daga layin dogo na 5V DC. Hasken da ake so yana cikin tsakiyar kewayon iyawar LED.

1. Zaɓi Halin Tuƙi:Zaɓi I_F= 10mA, wanda shine daidaitaccen yanayin gwaji kuma yana ba da kyakkyawan haske tare da dogon rayuwa.
2. Ƙayyade Ƙarfin Lantarki na Gaba na LED:Yi amfani da ƙimar al'ada daga takardar bayanin, V_F= 2.5V.
3. Ƙididdige Resistor na Jerin:R = (V_wadata- V_F) / I_F= (5V - 2.5V) / 0.010A = 250 Ohms.
