Infrared LED beads are important components widely used in remote control, night vision, security monitoring and other fields. In the market, common infrared LED chips have two emission angles of 120 degrees and 60 degrees. So, what is the difference between them? This article will provide a detailed analysis from the aspects of luminescence angle, illumination range, and application scenarios.

1、 Luminous angle

Firstly, from the perspective of luminescence, the 120 degree infrared LED beads have a wider luminescence angle than the 60 degree infrared LED beads. This means that under the same working conditions, 120 degree infrared LED beads can cover a larger area, making the light more evenly distributed. The emission angle of 60 degree infrared LED beads is relatively narrow, the light is relatively concentrated, and the irradiation range is small.

2、 Exposure range

Due to the different emission angles, there are also differences in the irradiation range between 120 degree infrared LED beads and 60 degree infrared LED beads. 120 degree infrared LED beads can cover a wider area, making the light more evenly distributed and suitable for scenes that require a larger illumination range. The illumination range of 60 degree infrared LED beads is relatively small, and the light is relatively concentrated, making it suitable for scenes that require precise illumination.

3、 Application scenarios

Due to the difference in emission angle and illumination range, 120 degree infrared LED beads and 60 degree infrared LED beads also have different application scenarios. 120 degree infrared LED beads are suitable for scenes that require a large illumination range and even distribution of light, such as security monitoring, nighttime lighting, etc. The 60 degree infrared LED beads are suitable for scenes that require precise illumination, such as remote controls, sensors, etc.

4、 Performance comparison

In addition to the emission angle, illumination range, and application scenarios, there are also differences in performance between 120 degree infrared LED beads and 60 degree infrared LED beads. Generally speaking, the intensity of 120 degree infrared LED beads is relatively weak because their light needs to cover a wider area. The intensity of 60 degree infrared LED beads is relatively strong because their light is more concentrated. In addition, due to the wider emission angle of 120 degree infrared LED beads, their heat dissipation performance is relatively better.

5、 Choose Suggestions

When selecting infrared LED chips, the appropriate light emission angle should be chosen based on the specific application scenario and requirements. If a larger irradiation range and uniform distribution of light are needed, 120 degree infrared LED beads can be selected; If precise illumination and strong light intensity are required, 60 degree infrared LED beads can be chosen. In addition, it is necessary to consider the quality and performance of the product, and choose reputable suppliers and brands.

In short, the difference between infrared LED beads at 120 degrees and 60 degrees mainly lies in the emission angle, irradiation range, and application scenarios. In practical applications, the appropriate type of infrared LED beads and corresponding suppliers and brands should be selected according to specific needs. By gaining a deeper understanding of the performance and applications of infrared LED chips, we can better meet practical needs and improve the quality and competitiveness of our products.
