LED Components Selection

How to choose a quality & Reliable Light Emitting Diode (LED)

Chapter 1 : Chips Selection

LED (Light Emitting Diode) will replace the bulb in the future (5-10 years), everybody in the world is chasing to make something out of this trendy technologies possible for their own use or business use.

However, selection of good LED components become important to those people who like to make thing happen.

Selection of LED start from selection of Chips technology. There are practically 3 types of chips technology available in the market :

• AlGaAs
• AllnGaP
• InGaN

Different type of chips emit different color. For example AlGaAs will only emit hyper red, AllnGaP will emit Red, Amber, Yellow & Yellow Green. Then InGaN will emit True Green & Blue. The emitting of WhiteLED is based on mixture of Yellow phospher and blue Chips from InGaN.

I will continue to explain the LED packaging selection in the next chapter.
