High power infrared light emitting diode (HP-IRLED) technology has become a crucial component in various industries, including automotive, medical, and industrial automation. This article aims to provide an in-depth introduction to the field of HP-IRLEDs, covering their working principles, applications, market trends, and future prospects.

Working Principles of HP-IRLEDs

High power infrared light emitting diodes are semiconductor devices that emit infrared radiation when an electric current is applied. These diodes consist of a p-n junction, where the p-type material has an excess of positively charged carriers (holes), and the n-type material has an excess of negatively charged carriers (electrons). When a forward bias voltage is applied to the diode, electrons and holes recombine at the junction, releasing energy in the form of infrared radiation. The key characteristics of HP-IRLEDs include: 1. High optical power output: HP-IRLEDs can generate output powers ranging from a few watts to tens of watts, making them suitable for various high-power applications. 2. Wide spectral range: HP-IRLEDs can emit radiation across a wide range of wavelengths, from near-infrared (NIR) to mid-infrared (MIR). 3. Efficient thermal management: High power devices generate significant heat, so efficient thermal management is crucial for their performance and longevity. 4. Long lifespan: With proper design and thermal management, HP-IRLEDs can have a lifespan of tens of thousands of hours.
