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 emit 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.
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 need batteries?
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. When LEDs get toward there end of life they fail by dimming over time, rather than an abrupt failure of incandescent bulbs.
Can I leave LED lights on all the time?
To put it simply, well-manufactured LED lights are extremely long-lasting and can be left on 24 hours, 7 days a week. This is because, unlike conventional types of light, LEDs produce minimal amounts of heat, which means they are unlikely to overheat or set on fire. In some scenarios, LEDs can and will fail.
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.
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.
What is inside LED bulb?
In order to explain how an LED works we must explain the four main components of an LED lamp; the LED Chip, the Driver, the The LED chip emits lights the in the bulb. Heat Sink, and the Optic lens. The driver then regulates the input current. The Heat Sink draws the heat away from the LED Chip.
How long do LED lights last?
One of the biggest advantages of LED light fixtures, is their extended lifespan. While incandescent light bulbs were built to last around 1,000 hours, the most enduring LED light fixtures have been tested to last as long as 100,000 hours. On average LED light bulbs will not have to be changed for at least 20 years.
How much electricity do LED lights use?
As the aforementioned GU10 LED bulb requires only 3.3 watts of electricity to produce 400 lumens, the equivalent to that of the 50 watt incandescent bulb, it will run at 0.0264 kWh/day.
How do you tell if a bulb is LED?
If you can see small chips that look yellow while the bulb is turned off, its an LED. If these details are hidden away, you can Google the partnumber on the base, or guess based on the light quality. If its greenish, its a CFL. If its a harsh bluish white its an LED.
How long do LED lights take to charge?
Depending on the power source used to charge the LED and how completely discharged the battery is, it may take anywhere from 30 minutes to 75 minutes for the battery to charge. The GlowClip LED light will glow red while the battery is charging and the red light will turn off once it is fully charged.
How do you charge LED lights?
Each battery pack has a red LED indicator light to show that it is turned on. Plug the battery pack into the charger, and make sure the charger is plugged into the wall. It will take eight hours for an empty battery pack to fully charge, so please, plan ahead!.
Do LED lights plug into the wall?
LED Power Supply Options: Plug-in Adapter – Plug straight into your wall to power your LED strip lights. Hardwire Power Supplies – Directly wire in between your line voltage wiring and your LED Strips.
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.
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.
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.
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.
How long do LED strip lights last?
LEDs have an unbelievably long expected life-span, compared to both incandescent and fluorescent lights. With an average life-expectancy of some 50,000 hours, LED strip lights will still be burning bright in 17 years’ time, long after their traditional counterparts will have expired.
