This article will introduce the basic concepts, characteristics, and application fields of 5mm white LED voltage, aiming to provide a comprehensive understanding of this topic for readers in the industry.

Introduction to 5mm White LED Voltage

The voltage of a 5mm white LED refers to the voltage required for the LED to emit light at its rated brightness. Generally, the voltage of a 5mm white LED is between 2.8V and 3.2V. This voltage range is suitable for most white LED products on the market. The specific voltage value depends on the LED's forward voltage and the current flowing through it.

Characteristics of 5mm White LED Voltage

1. Low forward voltage: Compared with other types of LEDs, the forward voltage of a 5mm white LED is relatively low, which makes it more energy-efficient and reduces the power consumption of the circuit. 2. High brightness: The brightness of a 5mm white LED is high, which is suitable for various lighting applications. 3. Wide color temperature range: The color temperature of a 5mm white LED can be adjusted within a wide range, from warm white to cool white, to meet different application requirements. 4. Long lifespan: The lifespan of a 5mm white LED is generally 30,000 to 50,000 hours, which ensures the stability and reliability of the product.

Application Fields of 5mm White LED Voltage

1. General lighting: 5mm white LED voltage is widely used in general lighting applications, such as home lighting, office lighting, and commercial lighting. 2.
