Single-color LEDs are semiconductor light sources that emit light within a specific wavelength range, producing a distinct color output. Utilizing various semiconductor materials, these LEDs serve a spectrum of applications, from indicators and displays to scientific uses and beyond.
Working principle
LED operates leveraging the phenomenon of electroluminescence within semiconductor materials. When a voltage is applied across the leads of a LED, electrons and electron holes recombine within the semiconductor material, releasing energy in the form of photons.
The energy of these photons determines the wavelength of light emitted, which is specific to the semiconductor material used in the LED. By controlling the semiconductor material’s composition and structure, we can produce LEDs that emit light in specific colors, such as red, yellow, green, or ultraviolet.
Red LED emits light primarily in the red part of the visible spectrum, typically around 610-760 nm. Its forward voltage is relatively low, around 1.6 to 2.0.
