This article is very cool and Lucius wants to share it with anybody, especially 3rd graders! The following article will teach you about light as well as LED lights. In our everyday lives, light plays a significant role. It is responsible for us being able to view everything around — the sun shining in the sky to the various lights in our homes. LED lightbulbs revolutionized home lighting, it became brighter and also, energy saving. Learning about the different colors of light produced by LED lights can shed some light (pun intended) about their operation and their effect on us.
It is a form of energy that we see wih our eyes. Light Light is a special type of energy. It moves in waves through the air, and it can make a lot of different colors. Think about a rainbow! The colors of a rainbow are purple, blue, green, yellow, orange, and red. Every color comes from a different wavelength of light. All of these colors combined makes white light — what we see when we turn on most of the lights in our homes.
LED Light Color (Kelvins) When discussing color of LED lights, we call them with how many Kelvins (K) they are. LED lights can vary in color temperature from warm white (2000K-3000K) to neutral white (3500K-4500K), and even to cool white (5000K-6500K). Warm white light is cozy and yellowish, cool white light is brighter and bluish. Put simply, the higher the Kelvin number the cooler and bluer the light appears. Such will help us to know what kind of light we are using in different situations.
LED grow lights have become extremely popular for cultivating plants Indoors. It is because they are more effective and less expensive compared to simple lighting sources. Light Spectrum Selection for Plants When it comes to growing plants with LED lights, selecting the correct colors of light is crucial. Plants do best with different colors of light and specific colors have specific purposes for plant growth.
For instance, blue light (400-500nm) is optimal for developing strong, vegetative growth in the plant. However, red light (600-700nm) is more beneficial when plants begin to flower and with the production of fruit. Then there is light falling in between blue and red (500-600nm) that plays a key role in maintaining plant health in general. By using the right colors for light that plants grow better and more faster — which we would all presume!
The light spectrum can be customized by mixing colors and creating different combinations. For example, you would mix red, green, and blue (RGB) colors to form multiple shades. Cool white and warm white LEDs may also be combined together. This means you can produce a multitude of colors and color temperatures as you need. You can customize the LED lights to be a bright light for getting work done, or a soft light for leading you up to bed!
Light of different colors by the way can be much more helpful. For example, blue light is commonly utilized in hospitals and health-care fixtures since it promotes the healing process. So that’s why you may observe blue lights in those locations. Green light is also an excellent option because it is commonly used in night lights. Color that is less harmful to our sleep than others and makes us sleep better at night.
