Infrared LED beads are a type of light source that emits infrared radiation and are widely used in consumer electronics, security monitoring, smart homes, and other fields. Next, let's follow Xinyouwei Radio and Television to learn about several aspects that need to be understood when choosing infrared LED chips.
(1) Luminous efficiency
The luminous efficiency of infrared LED beads refers to the brightness of light emitted per unit current. The higher the luminous efficiency, the less energy consumption and the longer the service life
(2) Emission wavelength
The emission wavelength of infrared LED beads determines their applicable application scenarios. At present, the common emission wavelengths of infrared LED beads on the market are 850nm and 940nm. 850nm is suitable for long-distance signal transmission, lighting, and security monitoring, while 940nm is suitable for close range lighting, biological detection, and wireless charging.
(3) Packaging form
There are two packaging forms for infrared LED beads: SMD and COB. SMD packaged LED beads have small volume and large emission angle, making them suitable for places that require high brightness and flexible layout; The COB packaged LED beads have high brightness and excellent heat dissipation performance, making them suitable for places that require high power output and long-term work.
