8mm yellow LED, also known as an 8mm yellow light-emitting diode, is a popular type of LED with a diameter of 8mm. This compact and efficient light source is widely used in various applications, ranging from indicator lights in electronic devices to decorative lighting in homes and offices. In this article, we will explore the 8mm yellow LED industry, including its history, technology, applications, and market trends.

History of 8mm Yellow LED

The development of the 8mm yellow LED can be traced back to the early 1960s when the first LEDs were invented. Initially, LEDs were only available in red, yellow, and green colors. Over the years, technological advancements have led to the production of LEDs in a wide range of colors, including yellow. The 8mm yellow LED has become a staple in the LED industry due to its compact size, efficient performance, and versatility.

Technology of 8mm Yellow LED

The 8mm yellow LED is made up of a semiconductor material that emits light when an electric current passes through it. The most commonly used semiconductor material for yellow LEDs is gallium nitride (GaN). When an electric current is applied, electrons and holes recombine within the GaN material, releasing energy in the form of light. The color of the light emitted depends on the energy band gap of the semiconductor material. The 8mm yellow LED typically has a forward voltage of around 2.0 to 2.2 volts and a forward current of 20 to 30 mA. The color rendering index (CRI) of these LEDs is usually around 70 to 80, which is suitable for general lighting applications. However, higher CRI values can be achieved by using different semiconductor materials or coatings.
