Infrared LED beads are a common light-emitting device widely used in various lighting and display devices. In design and applicationInfrared LED beadsUnderstanding its voltage value is very important. This article will introduce how to calculate the voltage value of infrared LED beads.

Firstly, we need to understand the specification sheet for infrared LED beads. The specification sheet usually provides parameters such as voltage and current values of the lamp beads. Generally speaking, the specification book will provide two voltage values: forward voltage and reverse voltage. Forward voltage refers to the voltage at which the light bulb emits light normally, while reverse voltage refers to the voltage at which the light bulb goes out.

The calculation formula for forward voltage is:

Forward voltage=(1.5 × VCC)/(R1 R2)

Among them, VCC is the power supply voltage, and R1 and R2 are the resistance values of series resistors. By using this formula, we can calculate the value of the forward voltage.

The calculation formula for reverse voltage is:

Reverse voltage=VCC - (I × R2)

Among them, I is the current value, and R2 is the resistance value of the series resistor. By using this formula, we can calculate the value of the reverse voltage.

It should be noted that the voltage value of infrared LED beads is affected by factors such as temperature, color, and manufacturing process. Therefore, in practical applications, we should make appropriate adjustments and corrections according to specific situations.

In addition, we also need to consider the impact of other factors on infrared LED beads. For example, excessive or insufficient current can affect the luminous effect and lifespan of the lamp beads; The high or low working environment temperature can also affect the performance of the lamp beads. Therefore, when designing and applying infrared LED beads, we should fully consider these factors to ensure their normal operation and optimal performance.

In short, understanding the voltage value of infrared LED chips is very important. Through calculation and correction, we can better grasp its performance and application scope, thus maximizing its advantages in practical applications.
