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! It essentially means that a material (in this case, the diode) casts light when power is applied to it.
How do LED lights work for dummies?
LEDs create light by electroluminescence in a semiconductor material. Electroluminescence is the phenomenon of a material emitting light when electric current or an electric field is passed through it – this happens when electrons are sent through the material and fill electron holes. … They emit photons (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.
Can LED lights be left 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.
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. … LED can make a big impact on your energy use.
Do LED lights attract bugs?
Because different types of bugs see different wavelengths, it is never guaranteed that an LED light won’t attract them. … LED lights produce little to no UV light and a minuscule amount heat, which makes them less attractive to bugs—so long as they emit longer wavelengths of light.
Why do LEDs fail?
When heat can’t dissipate from the heat sink, it can cause lamps to fail prematurely. Also keep the surrounding environment in mind. The hotter the room is, the earlier an LED light may degrade. … Because LEDs emit light that decreases exponentially as a function of time and temperature.
Are LED lights bad for your eyes?
The “blue light” in LED lighting can cause damage to the eye’s retina and also disturb natural sleep rhythms, according to a new report. … “Exposure to an intense and powerful (LED) light is ‘photo-toxic’ and can lead to irreversible loss of retinal cells and diminished sharpness of vision,” it said.
Why do my LED bulbs burn out so fast?
Unlike incandescent light bulbs, LEDs don’t produce light using heat. This is part of what makes them so energy efficient. The downside is that their components can be sensitive to overheating, which can cause them to burn out prematurely.
Is it OK to sleep with LED lights on?
All artificial light, including LEDs, fluorescent bulbs and incandescent bulbs, can interrupt normal sleep patterns. The body’s biological clock works in rhythms that are set by the amount of light and dark the body is exposed to. This is called the circadian rhythm.
What color LED lights should I sleep with?
What LED light color is best for your sleep? A red light color is best for sleep because it has a low color temperature, far lower than regular sunlight. You can be immersed in red light at night without giving your body a jolt and altering your internal clock as blue light does.
Is it bad to sleep with LED lights on?
Blue light, the type of bright light that comes from natural sunlight and the LCD/LED screens of our electronic devices, can boost our attention, reaction times and moods during the day. But at night, it disrupts our biological clocks and makes our bodies think we should stay awake when all we need is sleep.
What are the disadvantages of LED?
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.
Do LED lights heat up a room?
However, the answer is no. LED light bulbs will not cause an increase in room temperature because of their high efficiency. Because they are highly efficient, much less energy is transformed into heat. … LED bulbs must be kept cool, as high temperatures can cause failure or reduced light output.
WHAT LED bulb is equivalent to 100 watt?

|Incandescent Light Bulb Wattage||LED Equivalent Wattage|
|100 Watt||10 Watt|
|75 Watt||7.5 Watt|
|60 Watt||6 Watt|
