Introducing the 3535 LED, a compact and highly efficient lighting solution that has gained significant popularity in the LED industry. This article delves into the details of the 3535 LED, its applications, benefits, and its impact on the market.

Introduction to 3535 LED

The 3535 LED, as the name suggests, refers to an LED package with dimensions of 3.5mm x 3.5mm. This small form factor makes it an ideal choice for various applications where space is limited. The 3535 LED is part of the SMD (Surface-Mounted Device) family, which includes other popular sizes like 5050, 3528, and 2835.

Design and Construction

The 3535 LED is constructed using a standard SMD design, which includes a die attached to a substrate, typically made of PCB (Printed Circuit Board) material. The die is encapsulated in a transparent epoxy, which not only protects the die but also helps in the dispersion of light. The small size of the 3535 LED allows for a high packing density, making it suitable for applications requiring numerous LEDs in a compact space.

Efficiency and Power

One of the key advantages of the 3535 LED is its high efficiency. These LEDs can convert a significant portion of electrical power into light, making them energy-efficient. The typical forward voltage for a 3535 LED is around 2.8 to 3.2 volts, and the forward current ranges from 20 to 30 mA. This combination of voltage and current ensures optimal performance while keeping the power consumption low.

Color Options and Wavelengths

The 3535 LED is available in a wide range of colors, including red, green, blue, white, and RGB (Red, Green, Blue) combinations. The color is determined by the wavelength of the emitted light, which can vary from 620nm to 660nm for red, 470nm to 520nm for blue, and 460nm to 530nm for green. White LEDs are typically a combination of blue and yellow phosphors, which can also be adjusted to achieve different color temperatures.

Applications of 3535 LED

The compact size and high efficiency of the 3535 LED make it suitable for a variety of applications. Some of the most common uses include: -

Backlighting for LCD screens and keypads

-

Indicator lighting in electronic devices

-

LED strips and strip lights for decorative and functional lighting

-

Automotive lighting, such as brake lights and turn signals

-

General lighting in small spaces, like pico projectors and portable devices

Market Impact

The 3535 LED has had a significant impact on the LED market due to its versatility and efficiency. As the demand for energy-efficient lighting solutions continues to grow, the 3535 LED has become a staple in many lighting applications. Its small size has also allowed for innovative designs in consumer electronics and automotive lighting.
