No they do not use or make electromagnetic radiation to make light. The light is made with DC current made with capacitors to lower the voltage down from 110volts. In good LED lights there is power factor correction and power rectification to keep from polluting the AC line with extra sin waves.

What else can I help you with?
Can there be a light that does not produce heat?
LED .. Light Emitting Diodes , they're known for their very low energy consumption and they do not emit much heat. As of now , there is no kind of light which does not produce heat . But , LED's fit in as very efficient light emitters which produce very less heat. Also LED's have a life line which is way greater when compared to normal lights. Hope this helps =)
Which of these led to the ability to generate electricity from water power?
There were several things needed to start generating power from water. The wheel, the generator and the power transmissions system were all needed.

What radiation is the light bulb?
Incandescent light bulbs emit thermal radiation in the form of visible light and infrared radiation. LED light bulbs emit light through electroluminescence, a process in which electrical energy is converted directly into light without the production of thermal radiation.
Which television gives off more radiation LED or LCD?
LED, this is because a light emitting diode(LED) is a form of light that uses electricity and converts it into electromagnetic radiation -LEDs are therefore long lasting tech.
What object gives off light?
The sun is a natural object that emits light in the form of electromagnetic radiation, including visible light. Artificially, light bulbs and LED lights are examples of objects that produce light.
Do LCD screen emit radiation?
An LED TV does emit radiation. However, the amount is very small and not considered harmful. The radiation from an LED television is much less than the radiation that was emitted from older television models.
What type of energy does a flashlight give off?
A flashlight gives off light energy, which is a form of electromagnetic radiation. The light energy is created when the flashlight's batteries produce electrical energy that powers the light bulb or LED to emit light.
What important difference between radiation emitted by uranium and X-rays led him to this conclusion?
The main difference is that radiation emitted by uranium is due to the natural radioactive decay of its nucleus, while X-rays are electromagnetic radiation produced by accelerating charged particles. This led to the conclusion that X-rays are a form of light, whereas uranium radiation is a result of nuclear processes.
do flashlights use electromagnetic waves when creating light?
No, flashlights do not use electromagnetic waves to create light. Instead, they use electrical energy to power a light source, such as a bulb or LED, which emits visible light when energized. Electromagnetic waves are a form of energy that can transmit light, but they are not the source of light production in a flashlight.
Who made the discovery that found the electromagnetic theory of light?
James Clerk Maxwell unified the existing theories of electricity and magnetism into a single set of equations, which led to the discovery of the electromagnetic theory of light.
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.
Will LCD Clocks light up at Night?
LCD displays require an additional light source to light up in the dark. LED displays generate their own light.
What characteristics of the electromagnetic waves predicted by maxwells theory led him to suggest that light might be electromagnetic wave?
Maxwell's theory predicted that electromagnetic waves could travel at the speed of light, which was already known for light. He also found that these waves could exhibit properties similar to light, such as reflection, refraction, and interference, leading him to suggest that light might itself be an electromagnetic wave.
Where are visible light found?
Visible light exists within the electromagnetic spectrum and is the only type of light our eyes can detect. It is found in natural sources like the sun, stars, and fire, as well as artificial sources like light bulbs and LED lights.
