Introduction

The infrared emitter lamp, also known as an infrared lamp, is a type of lighting that emits infrared radiation. It has a wide range of applications in various industries, including medical, industrial, and consumer electronics. In this article, we will explore the history, working principle, applications, and future prospects of the infrared emitter lamp.

History of Infrared Emitter Lamp

The concept of infrared radiation was discovered in the early 19th century by British astronomer William Herschel. He observed that as the spectrum of sunlight was passed through a prism, there was a region beyond the red light that could not be seen by the human eye. This region was later named the infrared spectrum. The first practical infrared emitter lamp was developed in the late 19th century, and it was primarily used for medical purposes. In the 20th century, the applications of infrared emitter lamps expanded significantly. They were used in various industries, including agriculture, manufacturing, and military. With the advancement of technology, the efficiency and lifespan of infrared emitter lamps have been greatly improved, making them more versatile and widely used.

Working Principle of Infrared Emitter Lamp

Infrared emitter lamps work by converting electrical energy into infrared radiation. The process involves the following steps: 1. Electric current passes through a filament or a semiconductor material. 2. The filament or semiconductor material heats up due to the resistance to the electric current. 3. The heated filament or semiconductor material emits infrared radiation in the form of light. The intensity and wavelength of the emitted infrared radiation depend on the material and design of the lamp. There are different types of infrared emitter lamps, such as ceramic infrared emitter lamps, quartz infrared emitter lamps, and halogen infrared emitter lamps.
