Two Methods for White LED Light Production

That's correct. The two primary methods for producing white light from LEDs are fundamentally different in their approach and application. Here is a clear breakdown of those two methods:

SMD LEDs on Arduino Explained

When you look at an Arduino board, you will notice a few SMDs (surface-mount-devices). Like other components, LEDs can also be surface mounted. The RX and TX LEDs on Arduino are, as you might have guessed, examples of SMD LEDs. These types of LEDs don’t require any wiring and are soldered directly onto a circuit board.

Introduction to RGB LEDs

RGB is short for red, blue, and green. RGB LED is essentially LEDs in those colors put together. Combining those colors, RGB LED can produce almost any color, but it struggles with shades of pink and brown. With legs for each of the three colors, an RGB LED will have a fourth leg, for anode or cathode. When looking at an RGB LED, you should face it so the second leg from the left is the longest. They should then be in the following order: red, anode or cathode, green, and blue.

Bi-color and Tri-color LEDs Explanation

Bi-color and tri-color LEDs are components that light up in different colors depending on the direction or configuration of the electrical current.

The Development History of COB

Chip on Board (COB) is a mature technology in the electronics manufacturing industry, but its manufacturing process is unfamiliar to most electronics assembly plants. This is likely due to the fact that it utilizes integrated circuit (IC) packaging techniques such as wire-bonding. Consequently, many finished product assembly plants and specialized PCB foundries struggle to find skilled personnel.
