SMD 3528 is a type of surface-mounted LED (Surface Mount Device) that has become increasingly popular in the LED industry due to its compact size, high efficiency, and versatility. As the world continues to shift towards energy-efficient lighting solutions, SMD 3528 LEDs have emerged as a key component in various applications, from indoor lighting to outdoor signage.

History and Evolution of SMD 3528 LEDs

The history of SMD 3528 LEDs dates back to the late 1990s when the first surface-mounted LED packages were introduced. Initially, these LEDs were used in niche applications due to their high cost and limited performance. However, with advancements in LED technology and manufacturing processes, SMD 3528 LEDs have become more affordable and efficient, making them a staple in the LED industry. Over the years, SMD 3528 LEDs have evolved in terms of color, brightness, and lifespan. Initially, these LEDs were available in a limited range of colors, such as red, green, and blue. However, with the development of new materials and manufacturing techniques, the color range has expanded to include white, amber, and even RGB (red, green, blue) versions. Additionally, the brightness of SMD 3528 LEDs has increased significantly, with some models now boasting over 100 lumens per LED.

Design and Specifications

SMD 3528 LEDs are designed with a small, rectangular package that measures just 3.5mm x 2.8mm. This compact size makes them ideal for use in tight spaces and applications where a high density of LEDs is required. The package typically contains a single LED die, which is mounted on a PCB (Printed Circuit Board) using a conductive adhesive. In terms of specifications, SMD 3528 LEDs have several key parameters that determine their performance: - Forward Voltage: This is the voltage required to turn on the LED. For SMD 3528 LEDs, the forward voltage typically ranges from 2.0V to 3.2V, depending on the color. - Forward Current: This is the current that flows through the LED when it is turned on. For SMD 3528 LEDs, the forward current usually ranges from 20mA to 30mA. - Luminous Flux: This is the amount of light emitted by the LED. SMD 3528 LEDs can have luminous flux values ranging from 20 to 100 lumens, depending on the model and color. - Lifetime: This is the expected lifespan of the LED, measured in hours. SMD 3528 LEDs typically have a lifespan of 50,000 to 100,000 hours, depending on the quality of the LED and the application.
