How Does Color Changing LED Lighting Work?

Have you ever paused to think about how LED lights change colors? What makes them transform from a color to another instantly?

Today we are going to uncover the science behind color-changing LED lighting and how it works to create the magnificent display of various colors that we see in various gadgets around us.

Let's start with the basics.

What is LED lighting?

LED is an abbreviated form of Light Emitting Diode; they are tiny bulbs that use semiconducting materials to convert electricity into light. Compared to traditional light bulbs, LED lights are more energy-efficient, durable, and compact. They are used in various devices and gadgets, from toys and decorations to traffic lights and household lighting.

LED lights create different colors by emitting various wavelengths of light. Wavelength is the distance between the peaks of two successive waves, and it determines the color of the light that we see. The shorter the wavelength, the bluer the light, while the longer the wavelength, the redder the light.

How do color-changing LED lights work?

Color-changing LED lights feature tiny microchips that control the colors they emit. The microchip is responsible for adjusting the brightness and the wavelength of light that the LED bulb emits.

The most popular type of color-changing LED light is the RGB LED. It stands for Red, Green, Blue LED; these three colors produce white light. An RGB LED light consists of three LED lights that are mounted on the same chip. Each LED light has a different color; red has the shortest wavelength, followed by green, and blue has the longest wavelength.

When you switch on the RGB LED light, all the three LED lights turn on, producing white light. But if you want to change the color, the microchip in the RGB LED light switches off one of the LED lights and adjusts the intensity of the other two. For instance, if you want to get a red light, the microchip will switch off the green and blue LED lights, leaving only the red LED light on.

If you desire a different color, the microchip will adjust the intensity of all the three LED lights to produce a new color. For instance, if you desire a yellow color, the microchip will increase the intensity of the green and red LED lights equally.

Some color-changing LED lights come with additional colors; these lights feature more than one chip, and each chip contains RGB LED lights responsible for different colors. With such LEDs, the microchip chooses which chip to light up and the intensity of the different LEDs on that chip to get the desired color.

How does the microchip know which colors to choose?

Most color-changing LED lights come with remote controls, allowing you to choose the color that you desire. The remote control sends infrared or radio signals to a receiver inside the color-changing LED light. The receiver translates the signals and passes them to the microchip. The microchip responds by adjusting the colors appropriately.

Alternatively, some color-changing LED lights come with a smartphone application that you can install on your phone to control the colors that the LED light produces. The application communicates with the LED light through Wi-Fi or Bluetooth.

Conclusion.

In conclusion, color-changing LED lights work by emitting different wavelengths of light that produce varying colors. They feature microchips that control which LED bulbs to light up and the intensity of each bulb to achieve the desired color. With remote controls and smartphone applications, you can control the colors that the LED light emits.

LED lights are energy-efficient, durable, and compact, and they produce magnificent lighting displays that enhance the visual appeal of our living spaces. With the knowledge of how they work, you can unleash the full potential of color-changing LED lights and transform your living spaces into a magnificent display of colors.
