White Light Emitting Diodes or White LEDs are the next big thing in lighting. Earlier LEDs were restricted to applications like indicators, displays or emergency lighting.
What is white LED light good for?
White, natural lighting has many benefits and has become both cheap and accessible. LED bulbs give you control over the color temperature of your home as well as energy efficient lighting.
Are white LED lights bad for you?
The AMA says that life-long exposure of the retina and lens to blue peaks from LEDs can increase the risk of cataract and age-related macular degeneration. Studies also reveal that light emitted by LEDs can cause retinal changes, if there is high exposure for even a short period of time.
Are white LEDs blue?
White LEDs and the illumination breakthrough
Using different phosphors produces green and red light through fluorescence. The resulting mixture of red, green and blue is perceived as white light, with improved color rendering compared to wavelengths from the blue LED/YAG phosphor combination.
Is LED light white light?
Choosing the right color LED
The two most popular colors available for LEDs are soft white (also called warm white) and bright white (also called daylight). … If you want to get technical, the color of light on the white light spectrum is called color temperature, and it’s measured on the Kelvin scale.
What bulb is closest to natural light?
Halogen bulbs are a type of incandescent that gives a close approximation of natural daylight, known as “white light.” Colors appear sharper under halogen light and the bulbs can be dimmed. They’re a little more energy efficient than incandescent bulbs, but they’re more expensive and burn at a higher temperature.
Can you use white LED lights to grow plants?
Generally, yes. But because LED technology is so customizable, every bulb is different and you want bulbs that produce the exact mix of red, blue and other wavelengths preferred by your plants. White light contains a great mix for plants, so white LED bulbs will work to grow.
Is white LED light bad for eyes?
Scientists from the U.S. and Europe warn that LED lights could be doing more harm than good: A 2012 Spanish study found that LED radiation can cause irreversible damage to the retina.
Is sleeping with LED lights bad?
Leaving lights on at bedtime can lead to unsatisfying, disrupted sleep, not to mention all sorts of health risks. Keep these tips in mind to protect yourself from harmful blue light and to get better quality sleep. Power down your electronics.
Which LED light is best for eyes?
Warm light is best for the eyes. This includes filtered natural light and light produced by incandescent and LED light bulbs.
Why do white LED lights look blue?
Most “white” LEDs use a monochromatic blue source (not UV), which is then fluoresced to the lower frequencies with phosphor. Good phosphor is expensive, and more fluorescing hurts efficiency. Consequently, cheap LED sources tend to be blue and have a poor CRI.
Why do white LED lights turn yellow?
The heat generated even from a medium-power LED Chip is enough to discolor plastic. … You can see the white that it is supposed to be and the yellowing LED light discoloration that has occurred as a result of choosing a plastic cover.
What does warm white LED look like?
Warm White is a yellowish that resembles a traditional incandescent or halogen light. Cool White on its side, leans towards shades of blue and more like the light you would get from a neon.
Which is better warm white or cool white?
If you like the traditional yellowish colour of a conventional lamp then warm white around (2700-3000K ) would be the ideal choice, this is the most popular choice for homes. If you want a modern, clean look, you may prefer the cleaner, brighter feel of a cool white lamp (4000K+).
How do you make a white light LED?
There are two ways in which white light is produced from LEDs as below: Using a blue LED with a phosphor coating to convert blue light to white light by a process called fluorescence. Combining red, blue and green LEDs to produce white light.
How do I make my LED lights white?
In additive color mixing, red, green and blue light combine to make white light. Depending on the spectral output of the LEDs, not all three colors are always necessary.
