Do light-emitting-diode threat health?

Depends. Normally, no. Some suggest that the impure white light produced by LEDs can cause headaches. Also, due to the method of most white LEDs (blue LED coated with yellow reactive phosphor) used to produce the color some have suggested that the LED's blue light might be dangerous (see: blue-light hazard).


What are polarized LEDs?

Polarized LEDs are light-emitting diodes that emit polarized light, meaning the light waves oscillate in a specific direction. This property can be advantageous in certain applications, such as displays and optical communication, where controlling the orientation of the light is important for performance.


What are the different color spectra of a LED?

LEDs can emit light in different color spectra based on the materials used in the construction of the LED. Common colors include red (630-700nm), green (510-550nm), blue (450-495nm), and white (mix of different colors). Other colors like yellow, orange, and ultraviolet can also be produced by LEDs.


Chlorophyll and chloroplast are usually what color?

Chlorophyll is usually green in color, and chloroplasts, the organelles where chlorophyll is found, are also green. This green color comes from the absorption of red and blue light by chlorophyll, with green light being reflected and giving plants their characteristic color.


Do led has radiation?

LEDs can also be designed to emit light in the infrared spectrum, but the radiation emitted is very slight and only has limited use, such as communication between electronic devices using infrared ports and signals. Since the diodes are so small, they cannot easily be used to generate large amounts of heat. Other LEDs fall in the visible light spectrum, with some nearing ultraviolet light.

What does a bi-colour light emitting diode do?

There are actually two different LEDs of different color inside one package, wired so that either one or the other can light depending on how power is applied to the leads. Some bi-color LEDs will also permit both to light at the same time.

What color LEDs in Gallium used to make?

Gallium nitride (GaN) LEDs are commonly used to create blue LEDs. By combining a blue LED with a yellow phosphor coating or a green and red LED, white light can be produced. Additionally, different additives can be incorporated to create other colors such as red, green, and yellow LEDs.

What things have light energy?

Light energy comes from sources such as the sun, light bulbs, and fire. It also includes bioluminescent organisms like fireflies and deep-sea creatures, as well as artificial sources like lasers and LEDs.

What household items have leds?

LEDs make light, so some lights, usually outdoor ones, and some new TVs are LED backlit. Also most computer LCD screens are LED based. There are some more though.


What is a superflux led?

Superflux LEDs are the pinnacle of LED lighting. At a glance at the specifications it would appear that they are not as bright as the 3mm and 5mm LEDs, however with their 110 degree viewing angles they kick out an enormous amount of light. Making them perfect for vehicle stop lights, signs and many many more applications. Superflux LEDs are also known as Piranha LEDs. http://www.phenoptix.co.uk/Superflux_LEDs_s/35.htm


What can amber LEDs be used for?

Amber LEDs are good for when a person is camping because they don't attract as many insects. They can also make it easier to see in the dark as the eyes don't need as much time to adjust from light to dark with amber lights.


Where can you buy led light bulb cheap?

Most good electroics suppliers will have a range of LEDs for sale also such companies as Maplin who have stores and web outlets


What could you use a light emitting diode for?

There are many things you can use it for. If u have children can make a LED Christmas tree. Just type it into Google. Also ultraviolet LEDs are used to find scorpians as they light up under the light.
