Introduction

Infrared emitters are devices that emit infrared radiation, which is a type of electromagnetic radiation with longer wavelengths than visible light. These devices have become an integral part of various industries, including consumer electronics, automotive, medical, and industrial applications. The demand for infrared emitters has been on the rise due to their versatility and efficiency in transmitting signals and heat. This article aims to provide an overview of the infrared emitter industry, covering its history, types, applications, market trends, and future prospects.

History of Infrared Emitters

The concept of infrared radiation was discovered in the early 1800s by Sir William Herschel, an English astronomer. He observed that, when the sun's light was passed through a prism, there was a heat-producing region beyond the red end of the spectrum, which he named "infrared." This discovery paved the way for the development of infrared emitters. The first practical infrared emitter was the incandescent filament lamp, which was invented by Thomas Edison in the late 19th century. Since then, various types of infrared emitters have been developed, including infrared lamps, diodes, and quantum dots. The advancements in technology have led to the miniaturization and increased efficiency of infrared emitters, making them more suitable for a wide range of applications.
