An LED bulb produces light by passing the electric current through a semiconducting material—the diode—which then emits photons (light) through the principle of electroluminescence. Don’t let that big word scare you! The electrical resistance of the filament causes it to get so hot that it glows, producing light.
What is LED lighting and how does it work?
LED stands for light emitting diode. LED lighting products produce light up to 90% more efficiently than incandescent light bulbs. How do they work? An electrical current passes through a microchip, which illuminates the tiny light sources we call LEDs and the result is visible light.
How do LED lights produce light?
A diode, as in LED (Light emitting Diode), is a combination of different materials that does this and as a result light is emitted. As electricity passes through these materials the electrons in the compound become excited and emit photons of light.
Do LED lights need to be plugged in?
Do LED Lights Burn Out? LEDs draw very little power so they can run for a long time on a small battery without any issues. There is no need for a bulky wall transformer and a wall plug to light your project.
How do LED ceiling lights work?
LED lights work by passing a current through a semiconductor, compared to CFLs which use a current through gas, or incandescent bulbs, which pass the current through a filament, heating it up. Just make sure the power is off when you swap the bulbs. The clever tech needed to manage the current is built into the bulb.
Can I leave LED lights on all the time?
Because LED lights have good brightness, providing absolute safety for consumers when using them for service in life and extremely long life with 24/7 operating frequency, with LED lights you can turn on and Use them all day, no need to worry about explosion or damage when forgetting to turn off.
How long can LED lights stay on?
between 35,000 and 50,000 hours Type of Bulb Average Lifespan When should you turn it off? LED 35,000 – 50,000 hours Can be left on 24/7 Incandescent 750 – 2,000 hours Turn off when not needed.
Does LED lights get hot?
Yes, new technology LED lighting can and will get hot, but when compared to the lighting of the past, temperatures are much safer. The heat from the lighting will also warm your surrounding environment but in comparison to old incandescent lighting, this ambient heat is greatly reduced when using LED lighting.
Do LED bulbs work on AC?
LEDs consume DC current to produce light; with AC current the LED will only be lit when current flow is in the proper direction. AC applied to an LED will cause it to blink on and off, and at high frequency the LED will appear to be lit continuously.
Who created the LED?
The next year, in 1962, Nick Holonyak, Jr. (the “Father of the Light-Emitting Diode”) invented the first LED that produced visible, red light while working at General Electric. Throughout the 1960s, researchers and engineers continued experimenting with semiconductors with the goal of producing more efficient LEDs.
Can LED strip lights catch fire?
The possibility of led strip lights catching fire is minuscule, even though they are hot to touch. Incandescent bulbs have a filament that emits excessive heat, the light sources can ignite a fire on overheating, but as LED lights produce light at a lower temperature, they don’t catch fire as easily.
Where should I put my LED lights in my room?
5 great spots for LED strip lights around your home Under cabinets. As the name implies, under-cabinet lighting illuminates areas underneath your cabinetry. Along toe kicks. Under shelves. Under the bed. Behind computer and TV screens.
What happens when LED lights burn out?
LED lights cannot burn out because there is no use of heat as in incandescent bulbs, or gases to burn out or wires to burn up. The microchip inside the LED produces a small amount of heat, which is taken away by the heat sink, meaning that no parts in the bulb are designed to burn up.
What are the disadvantages of LED lights?
What are the disadvantages of LEDs? High up-front costs. Transformer compatibility. Potential color shift over lamp life. Performance standardization has not yet been streamlined. Overheating can cause reduced lamp life.
Why is it better to use LED lights?
LED is highly energy efficient – Less heat, more light, lower cost. Use less electricity for the same light output – 85% less electricity when compared to conventional lighting and around 18% less electricity compared to CFL.
Do LED lights require a special switch?
LED lights need their own special electronic dimmer switch to have a fully functioning and dimming light.
Do LED strip lights raise electric bill?
LED strip lights do not cost a lot of electricity compared to traditional incandescent lights. Consumption is directly determined by the length of the strip light and its light density. A standard 5-meter strip will cost less than $3 a year to run, on average.
Are LED lights safe for bedroom?
With all that in mind, the best answer to the question, “Is LED Light Safe?” would be: Yes, it is very safe. And that’s because the only demerit that LEDs have is that some of them emit blue light.
Do LED strip lights make your room hot?
Waveform Lighting LED strips are considered high power and high density, and therefore have a higher temperature rise than typical LED strip lights. In other words, for an LED strip in a typical room temperature environment of 75°F (24°C), you can expect the LED strip to reach a temperature of 129°F (54°C).
