Commonly available colors of led are red, green, blue, yellow, amber and white. the light from red, blue and green colors can be easily combined to produce white light with limited brightness. the working voltage of red, green, amber and yellow colors is around 1.8 volts. the actual range of working voltage of a light emitting diode can be. The light emitted by an led is usually monochromatic i.e. of single color and the color is dependent on the energy band gap of the semiconductor. light emitting diodes can be manufactured to emit all the wavelengths of visible spectrum i.e. from red (620nm to 750nm) to blue – violet (380nm to 490nm).
Leds (that's "ell ee dees") are a particular type of diode that convert electrical energy into light. in fact, led stands for "light emitting diode." (it does what it says on the tin!) and this is reflected in the similarity between the diode and led schematic symbols: in short, leds are like tiny lightbulbs. The light emitting diode is the most visible type of semiconductor diode. they emit a fairly narrow bandwidth of either visible light at different coloured wavelengths, invisible infra red light for remote controls or laser type light when a forward current is passed through them. the “ light emitting diode ” or led as it is more commonly. Led or light emitting diode is the most used electronic component in our daily life. it is a light source and in form of a small bulb that can be fitted inside a circuit. it is a special type of diode that converts electrical energy into light energy. unlike an incandescent bulb, it does not get hot, therefore it is an energy efficient light. A led or light emitting diode is an electrical component that produces light when current passes through it. leds are semiconductor devices, light is produced when the electrons combine with the material used as the semiconductor. leds can come in a variety of different shapes, colours and sizes. leds can produce the same amount of light around.

Wavelength and color. the led color (emission wavelength) will change depending on materials used. this makes it possible to customize the color to meet certain wavelength specifications required for applications that use traditional bulbs as light sources (for which standards exist), such as traffic lights and automotive lamps. Kelvin is the unit of measurement for color temperature (k). leds can emit light in various color temperatures. it can range from warm white (2700k–3000k) to cool white (5000k–6500k). a slower color temperature value indicates a warmer (yellowish) light. at the same time, a higher one indicates a cooler (bluish) light.
