Näidetéeled

Näidetéeled is a term used for a class of light-emitting diodes employed in educational kits to demonstrate basic electronics concepts. The name combines näide, meaning example in Estonian, with LED, signaling its role as a demonstrative component in teaching settings.

In practice, Näidetéeled modules are designed for ease of use. They typically operate from standard low-voltage supplies (often around 5 volts) and may include built-in current-limiting resistors or resistor networks. They are available in common colors such as red, green, blue, and yellow, with sizes typically in the 3–5 millimeter range. Some variants use integrated resistor arrays or color-coded markings to simplify experiments.

Design features emphasize compatibility with educational tools. Many Näidetéeled modules are mounted on small, breadboard-friendly boards or directly on prototyping surfaces. Variants include single-color LEDs, multi-color modules, and RGB LEDs, enabling demonstrations of color mixing, brightness control, and basic serial or parallel circuits.

Educational use and significance: Näidetéeleds are widely used to teach Ohm’s law, circuit topology (series and parallel configurations), forward voltage concepts, and the relationship between electrical current and light output. They are common in school laboratories, university outreach programs, and maker spaces, where hands-on experimentation supports theoretical learning.
