 The Infrared LED Strip Market: A Comprehensive Guide to China Manufacturers and Suppliers

The global market for Infrared (IR) LED strips is undergoing rapid expansion, driven by increasing demand across high-growth sectors like security
and surveillance, consumer electronics, and healthcare. China, as the world’s leading manufacturing hub for optoelectronics, stands at the forefront of this industry, housing a vast network of manufacturers and suppliers.This comprehensive guide provides an in-depth analysis of the Chinese IR LED strip market,key technologies, major applications, and a strategic framework for sourcing reliable suppliers.

Understanding Infrared LED Strip Technology

Infrared LEDs, unlike standard visible-light LEDs, emit electromagnetic radiation in the infrared spectrum, which is invisible to the human eye
but crucial for specific technological applications.

An IR LED strip is a flexible circuit board (PCB) populated with these IR emitters, often integrated with resistors and other components,
offering a versatile, linear, and low-power light source.

Key Spectral Ranges and Materials

The performance and application of an IR LED strip are primarily defined by the wavelength of light it emits.
Near-Infrared (NIR) (600 nm – 1,000 nm):
This is the most common range for IR LEDs. Wavelengths like 660nm, 850 nm and 940 nm are critical for security cameras, night vision, and remote controls.

Technical Specifications for IR LED Strips

Wavelength Measured in nanometers (nm), e.g.,660NM , 850 nm or 940 nm. Must match the sensor or application requirement.
Power Output Measured in milliwatts (mW) or optical power density. Dictates illumination distance.
LED Density Number of LEDs per meter (e.g.,5050 2835 30LEDS/M 60 LEDs/m, 120 LEDs/m). Affects light uniformity and power consumption.
PCB Material Quality of the Flexible PCB (FPCB), often copper content (e.g., 2oz) for better heat dissipation.
IP Rating Ingress Protection rating (ip20for indoor, IP65 AND IP67 for outdoor).
Voltage Typically 12V / 24V DC. Must match the power supply and system design

* Wavelength and Visibility: As it belongs to the infrared spectrum, the light from an 850nm LED strip is invisible to the human
eye under normal circumstances. However, in some cases, you might notice a faint red glow if you look closely.
* Brightness and Radiation Intensity: Compared to some other infrared wavelengths like 940nm, the 850nm LED strip has relatively
higher radiation intensity at the same current, which means it can provide stronger illumination in infrared applications.
* Forward Voltage Drop: Typically, when operating at a certain current (for example, around 20mA), the forward voltage (VF) of an
850nm LED is usually in the range of about 1.35 – 1.55 volts.
* Cuttable Design: Many 850nm LED strips are designed to be cuttable at specific intervals. This allows users to adjust the
length of the strip according to their actual needs easily.
* Long Lifespan: LEDs in general have a long service life, and 850nm LED strips are no exception. They often can last for more
than 50,000 hours, reducing the need for frequent replacements and maintenance costs.
