This article aims to provide an in-depth introduction to the 3535 LED, covering its history, technical specifications, applications, and future prospects.

History of 3535 LED

The 3535 LED was first introduced in the early 2000s by major LED manufacturers. Initially, it was used in low-power LED applications such as indicator lamps and small displays. Over the years, the 3535 LED has gained popularity due to its ability to produce high-quality light with a small footprint, making it suitable for a wide range of applications.

Technical Specifications

The 3535 LED is a surface-mount device (SMD) with a diameter of 3.5mm and a height of 3.5mm. It typically has a 5mm lead pitch, which allows for efficient assembly and high packing density on circuit boards. The 3535 LED comes in various colors, including red, green, blue, yellow, and white, and offers different brightness levels, ranging from 2000mcd to 8000mcd. One of the key advantages of the 3535 LED is its high efficiency. It can convert up to 70% of the electrical energy into light, which is significantly higher than traditional incandescent bulbs. This makes the 3535 LED an environmentally friendly and energy-efficient lighting solution.
