As technology advances, so must our knowledge!

That is why we have compiled a series of frequently asked questions through all the years of experience we have in the field of LEDs in order to teach you how do LED lights work in depth and to learn, in a easy way, all its capabilities and possibilities.

If you are an architect, interior designer or general contractor, knowing in depth about LED technology will undoubtedly raise the results in your work.

And if you are curious about how do LED lights work, knowing about it will help you make better energy decisions for your spaces.

Let’s get started!

1- ACTUALLY, HOW DO LED LIGHTS WORK?

LED is a highly efficient source of light energy. For its acronym: Lighting Emitting Diodes

Diodes are capable of generating light 50 times more than the old light sources: incandescent or halogen

The light produced by the diode comes through the activity generated by the electrons, stimulated by the negative voltage that comes across the semiconductors.

In simpler words: an LED is a chemical chip inside a plastic capsule.

2- WHAT COULD BE THE PROBLEM WITH THE LED LIGHTS?

The most common problems with LED lighting and how do LED lights work and perform are caused by its misuse, rather than by technology per se.

The incorrect use of color temperature in spaces can affect the way the brain interprets that light, thus changing the expected mood.

For example, if a room is intended and designed for relaxation, but has a white light color temperature, sleep and relaxation may be affected.

Similarly, the incorrect technical selection of the amount of lumens for a given space can generate visual discomfort.

Also, incorrect technical handling and installation of LED lights can affect its durability over time and its performance, causing flickering, glare and even early permanent damage to the lights.

3- CAN LED LIGHTS BE LEFT ON 24/7?

As long as the selection of the LED lights is appropriate for the space where they will be placed, there is a correct heat sink of the LED and the appropriate transformer or driver is used, then the LED lights can be left on 24 hours a day.

However, any source of electrical energy is a finite resource and we do not recommend wasting it.

Similarly, there are countless LED strip lights on the market that are not of the best quality and are sold without any type of appropriate indication for their uses or forms of installation.

If an LED strip is installed outside of an LED aluminum channel, you must be sure that its heat sink is optimal, otherwise the LED strip lights will shorter lifespan than it should and there will be other risks when leaving it on for long periods of time.

4- CAN LED LIGHTS CATCH FIRE?

This is quite unlikely to happen.

Incandescent bulbs generate light by burning their internal filament. This is why they can be at risk of catching fire.

But the how do LED light work is completely different. In the case of the LED, the light is generated through a chemical reaction in the Diode, therefore, there is no heat emission.

However, the LED does have some heat emission internally. If this internal heat is not dissipated correctly, not only will the LED burn out, but there could be a fire hazard.

This is why a professional LED strip of light with a light emission above 800lm / w must always be installed inside an LED aluminum channel for LED lights, in order to guarantee correct heat dissipation.

5- CAN THE LED LIGHTS BE TURNED ON AND OFF FREQUENTLY?

Without a doubt, this is a great advantage of LED technology.

There is no problem in frequently turning the LED lights on and off. Your internal circuit and system will not be affected.

Unlike halogen or incandescent lights, LED lights have a circuit design to handle frequent switching on and off, so when they’re turned on, they will reach their maximum brightness immediately without needing to “warm up”

6- ARE LED LIGHTS BRIGHTER?

One of the advantages and how do LED light work and its technology is the immense variety it offers in the market of lighting options.

LED lights will be as bright or dim as you want them to be. Its lum / w ranges can go from 300lm / w to above 3800lm / w.

What is true is that the most luminous ones significantly exceed the amount of light they emit compared to incandescent or halogen luminaires.

7- DO LED LIGHTS REALLY HELP YOU SAVE MONEY?

It is more than proven through many studies in addition to the experience of millions of people and experts in the field, that LED technology really is a great way to save money.

While LED lights are more expensive than incandescent or halogen bulbs, the real savings will be seen in your monthly electricity bill.

On average, a filament bulb consumes 40W of energy while an LED light will use only 5W.

At an energy expenditure rate of $ 0.19 per kWh, an LED strip consumes $ 19 / Year, while an incandescent light bulb will cost $ 152 in the same period of time.

8- WHAT ARE THEIR BENEFITS? ARE THEY RELATED TO HOW DO LED LIGHTS WORK?

– Long life: LED lights can reach 50,000 hours of use as long as their installation is appropriate.

– Energy efficiency: your savings are significant while using less energy and this is completely related to how do LED light work. 

– High intensity and brightness capacity

– Exceptional colors: LED lights are achieved in the three classic color temperatures in their perfect hues: cool white, neutral white and warm white; as well as in RGBY colors allowing to make combination games to obtain any color.

– Reliability: with LED lights you can achieve almost 100% visual perfection due to the high CRI levels that we can achieve in certain professional LED lights.

– Almost zero heat emission.

– Instant lighting: as soon as the LED lights are turned on, they reach their color and brightness immediately.

– Design possibilities: thanks to the great variety offered by the world of LED lights, a space can be designed entirely with lights creating unique environments.

9- CAN LED LIGHTS BE HARMFUL TO THE SKIN?

Incandescent light produces a certain amount of UV radiation that activates melanin in the skin, which can generate long-term darkening of the skin and possible adverse effects on its health.

LED lights, on the other hand, have been shown to have multiple benefits for the skin.

According to a publication made by students of Chemical Engineering at Stony Brook University, LED lights could take the healing position for the skin of some lasers, because through the exposure of LED light to human cells, they demonstrated activity and growth, generating tissue healing and new tissue.

Today, LED lights are not only used to illuminate a room but for medical and aesthetic treatments.

10- DEPENDING ON HOW DO LED LIGHT WORK, CAN LED LIGHTS BE DIMMED?

There are LED lights that are dimmable, however, not all of them can be.

LED strip lights are dimmable as long as their installation allows it. The dimming does not depend on the LED strip but on its driver or power supply.

However, as lighting designers, we frequently ask our clients the question: why dimmerize LED strip lights if you can decide in advance the amount of light and appropriate color temperature for the purposes of the space?
