This article aims to provide a comprehensive introduction to the 3mm amber LED, exploring its features, applications, market trends, and future prospects.

Introduction to 3mm Amber LED

The 3mm amber LED, also known as a 3mm amber light-emitting diode, is a type of LED that emits light in the amber color spectrum. These LEDs are typically used in indicator lights, signaling devices, and decorative applications due to their visibility in various lighting conditions. The size of the 3mm amber LED is approximately 3mm in diameter, making it one of the smallest LEDs available in the market.

Design and Construction

The 3mm amber LED is constructed using a semiconductor material, usually gallium arsenide (GaAs), which emits light when an electric current is applied. The LED is encapsulated in a transparent or diffused lens to control the light output and direction. The housing of the LED is usually made of plastic, which provides protection and helps to dissipate heat.

Features and Specifications

Some key features and specifications of the 3mm amber LED include: - Color: Amber, which is a shade of yellow with a reddish hue. - Brightness: Typically ranges from 500 to 1500 mcd (millicandelas), depending on the quality of the LED and the application. - Operating Voltage: Commonly operates at 2.0 to 2.5 volts. - Operating Current: Typically requires a current of 20 to 30 mA to achieve optimal brightness. - Life Expectancy: The lifespan of a 3mm amber LED can vary, but it is generally around 50,000 hours under normal operating conditions.
