LED is an acronym for Light Emitting Diode, so I assume the metal LEAD was intended. This question has been answered extremely well.

What is the energy change in a LED?
It changes from electrical energy to light energy
What kind of light bulb gives off the most heat?
Incandescent bulbs produce the most heat for a given amount of light; fluorescent lights produce much less heat, and LED produces the least.
Does a energy saver light bulb kill lizards?
It shouldn't, but if the bulb is being used to heat the lizard's terrarium it won't provide enough heat and the lizard may be lethargic. Use a proper terrarium heating lamp, not a CFL or LED bulb for that purpose.
How much energy can you save by turning on LED light for 3 minutes then shut off every hour?
If you run it for 3 minutes and off for 57 minutes each hour, it would save 95% of the energy.
What is an example of infrared light?
The energy consumed by a 100-watt GLS incandescent bulb produces around 12% heat, 83% IR and only 5% visible light. In contrast, a typical LED might produce15% visible light and 85% heat. Especially with high-power LEDs, it is essential to remove this heat through efficient thermal management.
Why Led bulb are better than filament bulbs for maximum reduction in the consumption of electrical energy explain?
LEDs produce visible light and not heat. Filament bulbs use much of their energy to produce heat. The LED bulb produces more light per watt consumed.
How could LED lighting reduce our demand for electrical power?
LED in lighting will reduce energy consumption and costs as well as reducing lighting re-lamping and associated maintenance costs, which will both reduce the environmental impact of lighting. Current incandescent lighting technology is based upon a filament and produces significant heat, which is a waste of energy. With LED, the energy is made directly into light, therefore much less energy is wasted as heat. by Rebecca Markham
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 =)
A What observation led Rumford to conclude that thermal energy and mechanical energy were related?
the motion of workers boring holes in a cannon and the heat being endless.. if heat were a liquid it would eventually run out
Why LED uses less electrical energy?
LED uses less electricity because LEDs convert electrical energy into light more efficiently than standard light bulbs. The resistive wire in a standard light bulb wastes the energy supply as heat whereas an LED light does not.
What is the job of a Light Emitting Diode LED?
Produce light efficiently (i.e. with little energy wasted as heat).
What is the difference between a LED light bulb and a regular?
a regular light bulb emits about 80% heat energy and only 20% light energy, whereas leds emit about 70 % light and 30% heat
What makes LED light fixtures energy efficient?
LED light fixtures are made out of clusters of very small, super energy efficient bulbs. Because many of those bulbs are used, LED lights can be built to mimic the effects of regular incandescent bulbs. A huge part of what makes LED bulbs so energy efficient is that they do not produce heat as incandescent light bulbs do.
What was James Joule famous for?
James Joule was a physicist who studied heat and is credited with the discovery of how heat related to mechanical work. His discoveries and studies led to the law of conservation of energy.
What energy is wasted from a lamp?
that is dependant on the wattage of the bulb, the wattage 40W, 60W, 100W, is the rated power that a bulb will use. 1kW is equal to 1000W 1kWh is equal to 1000W per hour. kW stands for kilo watt I hope that helps
How does energy from flashlight batteries compare to the light and heat the flashlight gives off?
This depends entirely on the efficiency of the lamp. Tungsten lamps tend to give off more heat than light, whereas LED technology give off more light than heat. By the laws of thermodynamics the sum of the energy that comes out of the system must equal the sum of the energy that goes into the system. So: Energy in batteries = Total light energy produced + Total heat energy produced The efficiency therefore becomes the ratio between produced light energy and heat energy.
Led or lcd puts out less heat?
Most televisions described as LED televisions are currently still LCD based but simply use LED illumination instead of cold cathode tubes. The LED illumination is somewhat more efficient and therefore less energy is converted to heat by the back lighting system. The latest generation of televisions are the true LED models, normally describned as organic LED or OLED. Unlike LCD televisions, these use LEDs to directly generate an image. The LEDs are therefore only turned on when they are needed. This substantially reduces the amount of energy being put into the illumination and so reduces the heat being generated. A typical LCD television with cold cathode lighting runs at around 100W. A similar LED backlit LCD model will draw somewhat less while the new OLED models are expected to reduce power consumption significantly.
