Introduction to LED Diodes

LEDs, or Light Emitting Diodes, are semiconductor devices that emit light when an electric current passes through them. They have become the preferred lighting technology over traditional incandescent bulbs and fluorescent tubes due to their energy efficiency, long lifespan, and environmental friendliness. The 12v 3mm LED dioda is a miniature version of these versatile devices, designed for applications where space is limited and brightness is required.

Technical Specifications

The 12v 3mm LED dioda operates at a voltage of 12 volts and has a diameter of 3 millimeters. It is typically available in a range of colors, including red, green, blue, yellow, and white. The following are some key technical specifications: - Forward Voltage: The voltage required to forward bias the dioda and make it emit light. For the 12v 3mm LED dioda, this is 12 volts. - Forward Current: The current that flows through the dioda when it is forward biased. This is usually specified in milliamperes (mA). The typical operating current for a 12v 3mm LED dioda is around 20mA. - Light Output: The amount of light emitted by the dioda. This is measured in milliwatts (mW) or lumens (lm). The light output of a 12v 3mm LED dioda can vary depending on the color and manufacturer, but it is generally low to medium in intensity. - Lifetime: The expected lifespan of the LED dioda. High-quality 12v 3mm LED diodes can have a lifespan of up to 50,000 hours.
