Emitter tube LED, or Emitting Diode Light Emitting Diode, is a type of light source that has gained significant attention in the lighting industry due to its high efficiency, long lifespan, and versatility. This article aims to provide an in-depth introduction to emitter tube LED technology, covering its history, working principle, applications, and future prospects.

History of Emitter Tube LED

The concept of LED technology dates back to the early 20th century when the first LED was invented by Oleg Vladimirovich Losev in 1927. However, it was not until the late 1960s that LEDs started to gain popularity as a lighting source. In the 1970s, researchers at General Electric (GE) developed the first emitter tube LED, which was a significant breakthrough in the lighting industry. Since then, emitter tube LED technology has evolved rapidly, with continuous improvements in efficiency, color rendering, and cost-effectiveness.

Working Principle of Emitter Tube LED

Emitter tube LED is a solid-state lighting device that emits light when an electric current passes through it. The basic structure of an emitter tube LED consists of a semiconductor chip, a lens, and a package. When an electric current is applied to the semiconductor chip, electrons and holes recombine, releasing energy in the form of photons. The lens then focuses the emitted light, directing it in a specific direction. The semiconductor chip is made of a material with a specific bandgap, which determines the color of the emitted light. For example, a chip with a small bandgap emits blue light, while a chip with a larger bandgap emits red light. By using different semiconductor materials and bandgaps, emitter tube LED can produce a wide range of colors.

Applications of Emitter Tube LED

Emitter tube LED technology has found numerous applications in various fields, including residential, commercial, industrial, and outdoor lighting. Some of the most common applications include: 1.
