Introduction to LED SMD 3535 3V 2W

The LED SMD 3535 3V 2W is a surface-mounted device (SMD) LED that measures 3.5mm x 3.5mm in size. As the name suggests, it operates at a voltage of 3V and has a power rating of 2W. This LED is known for its high luminous efficiency, which is a measure of how much light is produced per unit of electrical power consumed. The 3535 size is one of the most common SMD LED packages, offering a balance between size and performance.

Design and Construction

The LED SMD 3535 3V 2W is constructed using advanced semiconductor technology. It consists of a chip, a lead frame, and a lens. The chip is the heart of the LED, where the light is generated. It is made of gallium nitride (GaN) or silicon carbide (SiC), materials known for their high efficiency and ability to emit light at high brightness levels. The lead frame serves as the electrical connection between the chip and the external circuit. It is typically made of copper or aluminum and is designed to provide a stable electrical path for the current. The lens is the outermost part of the LED and is responsible for focusing the light into a specific beam pattern. The lens can be clear, diffused, or colored, depending on the desired application.
