3mm yellow LED, a compact and highly efficient light-emitting diode, has become a popular choice in various industries due to its small size and bright yellow light output. This article delves into the details of 3mm yellow LEDs, exploring their applications, technology, market trends, and future prospects.

Introduction to 3mm Yellow LED

3mm yellow LEDs are a type of surface mount device (SMD) that emits a bright yellow light. They are characterized by their small diameter, typically around 3mm, which makes them highly suitable for use in tight spaces. These LEDs are often used in indicator lamps, displays, and other applications where a small, bright yellow light source is required.

Technology Behind 3mm Yellow LED

The technology behind 3mm yellow LEDs is based on the principles of semiconductor physics. LEDs are made of a semiconductor material, such as gallium arsenide (GaAs), gallium nitride (GaN), or silicon carbide (SiC), which emits light when an electric current is applied. In the case of yellow LEDs, the semiconductor material is typically gallium nitride doped with indium (InGaN) or gallium phosphide (GaP).

The yellow color is achieved by the emission of photons with a specific energy level, which corresponds to the yellow part of the visible spectrum. The efficiency of the LED is determined by the quality of the semiconductor material and the design of the LED chip. High-quality 3mm yellow LEDs can achieve a luminous intensity of up to 50,000 mcd and an efficiency of over 100 lumens per watt.
