Cálculo de Resistencia para LED 2835

flux

0:31

Para calcular correctamente la resistencia de cada cadena necesito saber la corriente de trabajo que quieres usar.
¿Deseas operar cada cadena de 3 LED a, por ejemplo, 20 mA (valor típico), o prefieres otro valor?

He preparado los componentes para tu lámpara de 12 V con 129 LEDs SMD 2835 verdes en 43 cadenas de 3 LEDs, cada cadena con su resistencia serie calculada para operar a 20 mA.
Componentes a añadir:
La resistencia aproximada se calculó como:
R = (12 V – 3×3.1 V) / 0.02 A ≈ 135 Ω
