Encyclopedia of specifications and models of SMD LED



  SMD LEDs are typically used in LED lighting applications. The specifications and models of SMD lamp beads can vary based on the manufacturer and the specific application. Here are some key factors to consider:

  1. Package Type:

    • SMD lamp beads come in various package types, such as 3528, 5050, 2835, etc. The numbers in the names often represent the dimensions of the LED package in terms of length and width (in tenths of a millimeter). For example, a 3528 package would have dimensions of approximately 3.5 mm x 2.8 mm.
  2. Color:

    • SMD lamp beads are available in different colors, including red, green, blue, white, and various shades of each. Some SMD LEDs are RGB, allowing for a wide range of colors.
  3. Forward Voltage (Vf) and Current (If):

    • These parameters indicate the voltage and current required to operate the LED. Different colors and packages may have different forward voltage and current specifications.
  4. Luminous Flux:

    • This measures the amount of visible light emitted by the LED. It is typically measured in lumens.
  5. Color Temperature:

    • Color temperature is a characteristic of visible light and is usually specified in Kelvin (K). It defines the color appearance of the light emitted, ranging from warm (lower Kelvin values) to cool (higher Kelvin values).
  6. Viewing Angle:

    • The viewing angle describes the angular range over which the LED emits light effectively. It is often specified in degrees.
  7. CRI (Color Rendering Index):

    • CRI measures the ability of a light source to accurately render colors. It's a scale from 0 to 100, with higher values indicating better color rendering.
  8. Lifetime and Reliability:

    • Consider the rated lifespan of the LED and any information about reliability, especially if the application requires a long operational life.

To obtain specific information about the latest SMD lamp bead models and specifications, you may need to refer to datasheets provided by manufacturers or contact them directly.
