In the industrial field, precision and efficiency are crucial. Senior engineers, with their deep technical knowledge, look for solutions that optimize systems and minimize inconveniences. In this context, WorldWide WCE presents an innovation that will make a difference: miniature LED lamps with bipolar function.

Why is bipolar function relevant?

Miniature lamp sockets, such as Bi-Pin, Wedge Base or Sliding Base (Sliding Telephone Base, PSB) types, often do not display their polarity when powered by direct current (DC). This can lead to confusion and difficulties in lamp installation and replacement.

Imagine the situation: you try to turn on a lamp and it doesn't work. What's next? You have to remove it, turn it upside down and put it back in. This process is cumbersome and time-consuming, especially in industrial environments where every minute counts.

The solution: lamps with bipolar function

To avoid this inconvenience, WorldWide WCE offers a range of specially designed lamps with bipolar function. These lamps feature bi-directional rectification technology and dual chips. What does this mean? They are fully compatible with both alternating current (AC) and direct current (DC). No matter how they are connected, they will always work correctly.

Key Features:

  • Full compatibility: Bipolar function lamps are ideal for applications requiring flexibility in the power supply. They can operate without problems on AC or DC systems.
  • Standard LED Colors: WorldWide WCE offers a wide variety of standard LED colors, including warm white. This allows it to accommodate different signage and display needs.
  • Socket variety: The lamps are available in several types of sockets:
    • BiPin 2.54 / Ø 4.2: Model MWTP42xx
    • BiPin 3.17 / Ø 5.6: Model MWTP56xx
    • Sliding base for phones:
      • T4.5: Model MWTT45xx
      • T4,6: Model MWTT46xx
      • T5,5: Model MWTT55xx
      • T5,5 short: Model MWTK55xx
      • T6,5F (french socket T6,8F): Model MWCT65xx
      • T6,8: Model MWTT68xx
    • Wedge base:
      • W2x4,6d: Model MWTW46xx
      • W2,1x9,5d: Model MWGW95xx


These miniature LED lamps with bipolar function are the smart choice for engineers looking for quality, versatility and reliability in their industrial projects. No more guessing about polarity; simply install and turn on with confidence.
