How does LED radiation generates hydroxyl radicals?

The LED, light-emitting diode, is a passive electronic component. It comes up of semiconductor materials (such as silicon carbide) which, when crossed by an electric current, emit light energy. You need to know about LED radiation generates hydroxyl radicals.

Nowadays, LED lighting is the most efficient technology available, has a longer lifespan and is more sustainable than fluorescent lamps. Any traditional lamp can now be replaced with LEDs.

What are the advantages of the LED?

The table shows the main advantages of LED lighting:

Energy efficiency	They represent the most efficient technology, with the same lighting they consume much less, about 90% compared to halogen lamps and about 66% compared to fluorescent (low consumption) lamps.
LED light does not produce heat	The LED lamp does not heat up and therefore does not waste anything in heat unlike the obsolete incandescent bulbs.
Duration	LEDs have an average life of 50,000 hours, lasting about 20 years compared to the average life of a compact (low consumption) fluorescent lamp which is 10,000 hours.
No UV and infrared emissions	LED bulbs do not emit ultraviolet or infrared rays so they do not damage fabrics, leather or furniture and do not attract insects.
Immediate ignition	LED lamps immediately emit maximum light, and you won’t have to wait several minutes for the room to light up.
Aesthetics	The LED bulbs allow different shades: warm or cold white light and a wide range of colors: red, blue, green, yellow.
It does not pollute and it is not dangerous	The LED contains silicon powder, does not contain harmful gases and has no toxic substances.

LEDs (Light Emitting Diodes) have been common for years in electronics (remote controls, stand-by, etc.). The first LED came in 1962 by the US inventor Nick Holonyak Jr.!

What is LED radiation generates hydroxyl radicals?

LED lights save up to 90% of electricity compared to a traditional incandescent lamp. According to ENEA, switching from a medium-power halogen lamp to an energy-efficient LED allows you to save around 115 euros over the life of the lamp, and to recover its cost within a year. Hence, you need to check LED radiation generates hydroxyl radicals.

If we take into account the Christmas period, the month of the year where lighting becomes the protagonist, we will see that replacing a traditional Christmas chain with a LED one saves electricity and reduces CO2 emissions.

If 100,000 families decided to replace a traditional light chain with a 300-lamp LED tube, electricity saving of 1620 MWh and a reduction in CO2 emissions would be obtained. This shows how small choices can make a difference if made by more people.

Types of lamps

Lighting is very important and must be analyzed taking into account energy efficiency and the environment. About 80% of all the electricity we consume in our homes is common for lighting, but this consumption is easy to reduce by using more efficient lamps. To orient ourselves in choosing a light bulb, we have to take into consideration several parameters:

• the power expressed in Watts(W), to understand how much electricity it consumes;
• Moreover, the luminous flux expressed in Lumen(lm), the quantity of light energy emitted by the bulb;
• the luminance expressed in Lux(lx), the quantity of light that a surface receives;
• LED radiation generates hydroxyl radicals

 

Furthermore, we must verify the Total Cost of Ownership (TCO) that is the set given by the life time of the lamp, its cost and total dissipation.

Incandescent LED radiation generates hydroxyl radicals

Incandescent bulbs fall into two categories:

1. traditionalincandescent lamps ;
2. Halogenincandescent lamps.

Traditional incandescent lamps have been banned since 2012. Incandescent technology has dominated the lighting industry for years. And now we are seeing its decline to make room for more efficient technologies. In general, the higher the initial cost for a given lamp corresponds to a lower operating cost: longer life and lower consumption.

“Halogen” incandescent bulbs

Halogen lamps are easy to divide into two large groups:

1. very low voltage;
2. at mains voltage.

Among the halogen lamps we also find the IRC (Infrared coating) or energy-saving lamps that absorb less energy and last longer (4,000 hours). Halogen incandescent lamps were abolished this year. Consumers (lower electricity consumption) and the environment (CO2 emissions reduction) will benefit from this decision.

But this announcement concerns only a specific type of LED radiation generates hydroxyl radicals.

Fluorescent lamps with LED radiation generates hydroxyl radicals

Compact fluorescent lamps, such as LEDs, are part of the energy saving bulbs on the market. These bulbs consist of a glass tube internally coated with a layer of special fluorescent powders, with low pressure mercury vapor.

The two electrodes, at the end, generate a discharge when the current passes. It associates with the emission of light radiation. Fluorescent lamps are divided into:

1. tubular fluorescentlamps (neon);
2. Compact fluorescent lamps( CFL).

Compact fluorescent lamps have a lifespan of 10 thousand hours and have a high luminous efficiency. Using these lamps, consumption is about 75% lower than with halogen lamps.

THE CONTINUOUS PROGRESS OF LED TECHNOLOGY

The technology applied to lighting is constantly evolving, responding to ever greater needs from consumers and allowing results that were previously unthinkable.

Since 2011 the first 100 lumen per Watt light emitting diodes have been produced, reaching the efficiency of compact fluorescent lamps.

Types of LED radiation generates hydroxyl radicals

There are variations of LED models, some of them are:

• Ordinary LEDs:the light from these LEDs is scattered by their plastic capsule. The objective would be for the light to be uniform along the surface of the LED, but even so there are points with higher and lower brightness;
• High-brightness LEDs: the luminous power of these LEDs is much higher than that of LEDs, for example. The plastic capsule is transparent, which increases the brightness of the LED, its light is concentrated;
• LED strips:as the name suggests, it is a strip that has, in its extension, several tiny LEDs, shining together or alternating, depending on the strip model;
• Bicolor LEDs: they can be transparent, have two colors, or the combination of two colors to form a third color. It may have two or three terminals;
• RGB or tricolor LEDs: they have three colors, red (Red), green (Green) and blue (Blue). They can be diffuse or transparent. Colors can be common together or individually;

Summary LED radiation generates hydroxyl radicals

All the technology that revolves around the production of a quality and high-performance LED source has progressed in recent decades. Hence, it allows us to produce lamps with unsurpassed performance associated with the maximum possible savings.
