WebbA CM white LED made by InGaN blue, cyan, green, and yellow LEDs and AlGaInP red LEDs was demonstrated with Ra as high as 97.5, luminous efficacy above 120 lm/W, … AlGaInP can be used as an LED. An LED is composed of a p-n junction which contain a p-type and an n-type. The material used in the semiconducting element of an LED determines its color. AlGaInP is one of type of LEDs used for lighting systems. Another is indium gallium nitride (InGaN). Slight changes in the composition of these alloys changes the color of the emitted light. AlGaInP alloys are used to make red, orange and yellow LEDs. InGaN alloys are used to make green, bl…
