3535 LEDs, also known as 3535 surface mount diodes, have become a popular choice in the LED industry due to their compact size and high efficiency. These LEDs are designed with a 3.5mm x 3.5mm package, which makes them ideal for various applications requiring a dense arrangement of light sources. This article will delve into the world of 3535 LEDs, exploring their features, applications, and the impact they have on the industry.

Introduction to 3535 LEDs

3535 LEDs are a type of surface mount LED, which means they are mounted directly onto a printed circuit board (PCB) without the need for leads. The compact size of these LEDs allows for a higher density of lights on a single PCB, making them suitable for applications where space is limited. The 3535 package size is smaller than the more common 5050 and 3528 packages, which makes them a preferred choice for high-resolution displays and compact lighting solutions.

Design and Specifications

3535 LEDs are typically made using a high-quality aluminum nitride (AlN) or sapphire substrate, which provides excellent thermal conductivity and mechanical strength. The die size within the 3535 package is usually around 1.5mm x 1.5mm, and the LEDs can emit light in a range of colors, including red, green, blue, white, and RGB. The luminous intensity and color temperature of these LEDs can vary depending on the manufacturer and the specific application requirements.
