With the rapid development of technology, infrared LED has become an indispensable part of our lives. As a key parameter in the design and application of infrared LED, forward voltage plays a crucial role. This article will introduce the concept, characteristics, and application of infrared LED forward voltage, aiming to help readers understand this important parameter in the industry.

Introduction to Infrared LED Forward Voltage

Infrared LED forward voltage refers to the voltage required to make the infrared LED emit light. It is a critical parameter in the design and application of infrared LED, which directly affects the efficiency and stability of the LED. In general, the forward voltage of an infrared LED is between 1.2V and 3.5V, depending on the material and structure of the LED.

Characteristics of Infrared LED Forward Voltage

1. Non-linear relationship with current The forward voltage of an infrared LED is not a linear relationship with the current. When the current increases, the forward voltage will increase, but the rate of increase is not constant. Therefore, in the design and application of infrared LED, it is necessary to consider the non-linear relationship between forward voltage and current. 2. Temperature dependence The forward voltage of an infrared LED is also affected by temperature. Generally, as the temperature increases, the forward voltage will decrease. Therefore, in the application of infrared LED, it is necessary to consider the temperature influence on forward voltage to ensure the normal operation of the LED. 3. Material and structure dependence The forward voltage of an infrared LED is also related to the material and structure of the LED. Different materials and structures will lead to different forward voltages. For example, the forward voltage of a GaAs infrared LED is generally higher than that of a GaAlAs infrared LED.

Application of Infrared LED Forward Voltage

1. Infrared communication Infrared communication is one of the most common applications of infrared LED. The forward voltage of the infrared LED is used to control the current and ensure the stable transmission of the signal. In the design of infrared communication equipment, the forward voltage of the infrared LED needs to be considered to ensure the normal operation of the equipment. 2. Infrared remote control Infrared remote control is another important application of infrared LED. The forward voltage of the infrared LED is used to control the current and ensure the stable transmission of the signal. In the design of infrared remote control devices, the forward voltage of the infrared LED needs to be considered to ensure the normal operation of the device. 3. Infrared detection Infrared detection is also an important application of infrared LED. The forward voltage of the infrared LED is used to control the current and ensure the stable detection of the target. In the design of infrared detection equipment, the forward voltage of the infrared LED needs to be considered to ensure the normal operation of the equipment.

Conclusion

Infrared LED forward voltage is a key parameter in the design and application of infrared LED.
