Using LED RGB for decorating may bring a surprise
While LED RGB is not a strange concept, and RGB LEDs have been widely used in many areas, at public places, not many people know or understand it clearly. We will be looking closer at its structure, capability and uses in the article below.
Definition
LEDs (short for Light Emitting Diode) are diodes that are capable of emitting light or infrared and ultraviolet rays. LED RGB is a lighting system that combines 3 basic light sources: red (Red), green (Green), and blue (Blue).
LED RGB is a combination of 3 colors: red, green, and blue.
So LED RGB is a type of LED with multi-color light and the flexible color changing ability. Products are commonly used in many different fields, present in most stages, indoor and outdoor events, bars, etc.
Several variations of RGB LEDs
- LED AGRB
LED ARGB is a type of LED chip in which each LED eye is able to display separate colors, while in a normal RGB LED, a LED chip strip will display just a single color.
- Rainbow LED Lights
LED Rainbow is a 7-color LED with embedded chips in RGB LED that can change the intensity of light to create a shimmering, waveform color effect.
Rainbow LED systems can change color in either pre-programmed or controlled mode and they are often used in many computer accessories such as keyboards, mice, speakers, etc.
Structure
The LED RGB part consists of a light bulb and 4 contact pins, which include 1 common positive pin (anode) and 3 negative pins (cathode) equivalent to the 3 colors red, green, and blue. The color of the LED changes depending on the pin of the LED which is controlled by the PWM pulse.
The control board part of a basic RGB LED: Normally, to control the color of the light, we will have a panel with a voltage of 5 - 24V.
This circuit board will help users change the colors as well as create many different color gamuts, and adjust the light intensity to best suit the space that needs the light source.
RGB LED uses a microcontroller circuit to produce a variety of colors. The circuit will produce the following 8 basic colors.
Popular types of RGB LEDs
5-mm RGB multi-color LED
The 5-mm RGB LED has three main colors, namely red, blue, and green.
Suitable for temperature conditions from 30-60 degrees C, and diode voltage of 3-4V, the current supply for each 5-mm RGB bulb requires stability to maintain a good light source.
LED RGB aluminum bar
The voltage of the LED aluminum bar is 12V, and the thickness of the LED is 1 m, comprising 7 colors and 4 wires.
This type of LED is widely used in karaoke rooms, restaurants, advertising boxes, product display boxes, etc.
RGB molded LED
The voltage of this LED is 5V, the structure is more complicated than some other LED types and the light emitted is also considered beneficial to the eyes.
Molded RGB LEDs are widely used to decorate karaoke rooms, stages, or billboards with soft light sources, not dazzling to the viewer.
LED String RGB 200V
This is a 7-color LED coil light, the length of which is up to 100 meters, often used in decoration at large and long space, highly suitable as decorative wrapping for ornamental plants.
LED tube RGB
The product can change color thanks to computer programming, commonly found in decorative ceiling lights with a bulb capacity of 10W or 20W.
LED Strips RGB
This type of LED wire gives very vibrant, shimmering colors. The power of this LED wire is 9 W/m, the maximum heat resistance is 50 degrees Celsius, and is wrapped by a very flexible silicone shell.
