In this article, we will delve into the details of the 8mm red LED voltage, exploring its characteristics, applications, and the factors affecting its performance.

Introduction to 8mm Red LED Voltage

The 8mm red LED voltage refers to the voltage required to drive the 8mm red LED. This type of LED is commonly used in various applications due to its small size, low power consumption, and high brightness. The voltage required for an 8mm red LED can vary depending on the specific model and the quality of the LED chip.

Characteristics of 8mm Red LED Voltage

1. Forward Voltage: The forward voltage of an 8mm red LED is typically around 1.8V to 2.2V. This means that the LED will start to emit light when the voltage across its terminals reaches this range. 2. Forward Current: The forward current of an 8mm red LED is usually around 20mA to 30mA. Operating the LED at a higher current can increase its brightness but may also reduce its lifespan. 3. Luminous Intensity: The luminous intensity of an 8mm red LED is measured in millivolts (mV) or candela (cd). This parameter determines the brightness of the LED. 4. Color Temperature: The color temperature of an 8mm red LED is around 6200K to 6300K, which gives it a warm red color.

Applications of 8mm Red LED Voltage
