What are AlGaAs, AlInGap and InGaN?


    These are chemical symbols used for materials used in the manufacturing process of the LEDs to generate specific colors.


    AlGaAs - Aluminium Gallium Arsenide used to generate red and amber portions of the visible spectrum.

    AlInGap - preferred chip technology using Aluminium, Indium, Gallium and phosphorous to produce red, orange and amber colors.

    InGaN - Indium, Gallium and Nitrogen to produce green, blue and white colors.
