How does LED light turn white
The LED emits ultraviolet radiation, not visible to human eye, which falls on the red, green, and blue phosphors and excites them. When these RGB phosphors gets excited, they emit radiations which are mixed together to provide a white light.

Can LED lights turn white
RGB LEDs can produce white light by mixing the primary red, green and blue lights together in theory. But the mixture includes blending and diffusion of colors, creating factitious white light. This kind of white light seems to be covered with fog.
What color LEDs make white
White light can be achieved with LEDs in two main ways: 1) phosphor conversion, in which a blue or near-ultraviolet (UV) chip is coated with phosphor(s) to emit white light; and 2) RGB systems, in which light from multiple monochromatic LEDs (red, green, and blue) is mixed, resulting in white light.

How is white light produced
White light is a combination of all colors in the color spectrum. It has all the colors of the rainbow. Combining primary colors of light like red, blue, and green creates secondary colors: yellow, cyan, and magenta. All other colors can be broken down into different combinations of the three primary colors.
How does a LED change color
The different materials in today's semiconductors are used to create controlled energy levels. From there, colored diodes reflect the elements used for each product. Color-changing LEDs contain three separate diodes within the same bulb, and each of these diodes emits its designated color – red, green, or blue.
Are all LED lights bright white
Both incandescent and LED bulbs offer soft white and daylight options. Consider the room where you will use the light bulbs to offer the best light in your home. Dimmers allow you to change the intensity of light in a room.

Are all white LEDs blue
Almost all "white" LED grow lights on the market today are actually just a blue LED with a phosphor coating which converts much of the blue light into different colors.
How do RGB lights make white
If you mix red, green, and blue light, you get white light.
As more colors are added, the result becomes lighter, heading towards white. RGB is used to generate color on a computer screen, a TV, and any colored electronic display device.
Can we create white light
If we keep adding all these different colors. We can build up an entire spectrum to give white. Light. However you may know that we can create white lights from just red green and blue lights.
How is color or white LED light produced
Phosphor conversion, in which a phosphor is used on or near the LED to convert the colored light to white light. Color-mixed systems, in which light from multiple monochromatic LEDs (e.g., red, green, and blue) is mixed, resulting in white light.
Why does LED turn blue
The enemy of the LED's phosphor is the heat and UV radiation it emits during operation. Over time, these two forces degrade the phosphor and break down its components. The result is a fixture that used to give off nice white light but is now a little off—perhaps a bit blue or pink or green.
Why do LED bulbs glow white
Common LED colors include amber, red, green, and blue. To produce white light, different color LEDs are combined or covered with a phosphor material that converts the color of the light to a familiar “white” light used in homes. Phosphor is a yellowish material that covers some LEDs.
Is LED yellow or white
Not only can you choose between dozens of different energy efficient bulbs, you can also opt for different colors of lighting as well. Most CFL lights offer what is known as cool light, or white light, while LED lighting can be found in both cool and warm (yellow) light.
What is the original color of LED
(the “Father of the Light-Emitting Diode”) invented the first LED that produced visible, red light while working at General Electric. Throughout the 1960s, researchers and engineers continued experimenting with semiconductors with the goal of producing more efficient LEDs.
What color does LED produce
LED lights come in a range of colours from soft yellows to bright whites. Warm light tends toward yellows, reds, and oranges. Cool light appears blue or greenish.
Do white LEDs exist
In 1996, the Nichia Company announced the production of white LEDs, and the rest is history. For the past twenty years, the power, efficiency, and brightness of these LEDs has increased.

Why is RGB white not white
RGB LEDs cannot produce pure white light because there is no such thing. Nothing can produce pure white light. White is the experience of all colour receptors firing off at the same time… or a subset firing off too much. Either way, it is not it's own colour.
Can RGB LED make warm white
Although RGB can produce a colour close to white, a dedicated white LED provides a much purer white tone and allows you the option of an extra warm or cool white chip. The extra white chip also provides extra scope for colour mixing with the RGB chips to create a huge range of unique shades. Which is better
How does RGB make white
If you mix red, green, and blue light, you get white light.
Red, green, and blue (RGB) are referred to as the primary colors of light. Mixing the colors generates new colors, as shown on the color wheel or circle on the right.
Is white light made of RGB
The different brightness values of red, green and blue become dramatically apparent. In the RGB system the maximum values of red, green and blue are adjusted so that the combination of the three colors will produce white. The amounts of the three component colors are not equal.
Who created the white LED
Nakamura has also worked on green LEDs, and is responsible for creating the white LED and blue laser diodes used in Blu-ray Discs and HD DVDs. Nakamura is a professor of Materials at the University of California, Santa Barbara.
Are LED lights white or yellow

Are blue LED lights healthy
Research shows blue light exposure may lead to age-related macular degeneration, or AMD. One study found blue light triggered the release of toxic molecules in photoreceptor cells. This causes damage that may lead to AMD.
