Infrared fill light LEDs, also known as infrared LED fill lights, have become increasingly popular in various industries due to their excellent performance and wide range of applications. This article aims to provide a comprehensive introduction to the infrared fill light LED industry, covering its history, technology, applications, market trends, and future prospects.

History of Infrared Fill Light LEDs

The concept of infrared fill light LEDs originated from the field of photography. In the early 20th century, photographers began to use infrared light to capture images that were invisible to the naked eye. However, due to the limitations of technology at that time, infrared light sources were relatively expensive and inefficient. With the advancement of semiconductor technology, infrared LEDs were developed, which made infrared fill light LEDs more accessible and cost-effective. In the 1980s, infrared fill light LEDs started to gain attention in the medical field. They were used in medical imaging systems to enhance the visibility of tissues and blood vessels. Later, with the rapid development of LED technology, infrared fill light LEDs found their way into various other industries, such as security, automotive, and consumer electronics.

Technology of Infrared Fill Light LEDs

Infrared fill light LEDs are based on the principle of electroluminescence, where electrons and holes recombine at the PN junction of a semiconductor material, emitting light in the infrared spectrum. The key factors that determine the performance of infrared fill light LEDs include the material, structure, and driving mode. The most commonly used material for infrared fill light LEDs is gallium arsenide (GaAs). GaAs-based infrared LEDs have a longer wavelength and higher intensity than other materials, making them ideal for various applications. In addition, the structure of the LED, such as the p-n junction and the package, also plays a crucial role in determining the performance and lifetime of the device. The driving mode of infrared fill light LEDs is another critical factor. A proper driving mode can ensure the stability and longevity of the device. Common driving modes include constant current, constant voltage, and pulse width modulation (PWM).
