Introduction to LED Dioda 12V 3mm

The LED dioda 12V 3mm refers to a specific type of LED that operates at a voltage of 12 volts and has a diameter of 3 millimeters. These LEDs are known for their small form factor, which makes them suitable for embedding into various electronic devices and applications. The 3mm size is particularly popular in the hobbyist and DIY electronics communities, as well as in some commercial products.

History of LEDs

LEDs, or Light Emitting Diodes, have been around since the early 20th century. However, it wasn't until the 1960s that LEDs began to be used as a practical light source. The first visible-spectrum LED was developed by Nick Holonyak Jr. at General Electric in 1962. Since then, the technology has advanced significantly, leading to the development of various types of LEDs with different colors, intensities, and voltages.

How LED Dioda 12V 3mm Works

An LED dioda 12V 3mm operates on the principle of electroluminescence. When an electric current passes through the diode, electrons recombine with electron holes within the semiconductor material, releasing energy in the form of photons. This process is what produces light. The color of the light emitted depends on the semiconductor material used in the LED. In the case of the 12V 3mm LED, the semiconductor material is designed to operate efficiently at 12 volts. The small size of the LED is achieved by using a highly efficient, compact semiconductor chip that is mounted on a tiny, heat-conducting substrate. The substrate helps to dissipate heat, ensuring that the LED remains cool and maintains its longevity.
