What is the definition of led lights

Let there be LEDs

Light is one of the most important foundations for life on our planet. With the help of sunlight, plants produce oxygen, which is important for living things. And man ticks with the ups and downs of the solar phases. Light influences our mood, regulates important body functions as well as sleeping and waking phases. We bridge the dark hours of the day with artificial light. Illuminated everyday life is a matter of course for us, and so has high-tech lighting.

In contrast, artificial light is difficult to afford for people in developing countries - and it is often associated with harmful effects on the environment because traditional lighting such as kerosene lamps are used. But modern lighting technologies are also finding their way here.

Accompany us through a day full of LED technology - the light for life

Deep black night. The starlight shimmers through the mangrove forests of Sri Lanka. The swamp-like labyrinth on the Indian Ocean is the workplace of a shrimp fisherman. His day begins when the rest of the islanders are still deeply asleep. Sitting in his boat, the fisherman roams the dark swampy landscape every night in search of the crustaceans, assisted by a small lamp that he dips into the water again and again to attract the shrimp and fish them with his nets.

At first glance, the fishing method looks like a traditional ritual of the islanders, but the lamp contains an innovative technology: light-generating diodes, or LEDs for short. Thanks to the waterproof LED light, the fisherman caught hundreds of shrimps in the net that night as well.

When the day awakens

When the fisherman's working day ends at sunrise, the day begins a few hours later in Europe. The light of the LED alarm clock on the bedside table slowly illuminates a businessman's bedroom and gently wakes him up from his sleep. LED lamps automatically illuminate the hallway upon entering.

Intelligent and energy-saving lighting systems have already registered via the sensors of a motion detector that someone is entering the aisle. The light comes on without delay - another advantage of the semiconductor-based lighting solution.

On the way to work

In the twilight of the sunrise, the businessman makes his way to work, safely accompanied by LED car headlights that evenly illuminate the street. Brightly shining street lamps also ensure optimal illumination of the way to work.

When he reaches the parking lot with his car, the motion detectors are activated - and the parking lights come on automatically. Thanks to the parking beacon system, which shows free spaces in green and occupied spaces in red, they don't have to search long for a parking space.

The parking lights go out in a flash as soon as the businessman has entered the building. This is made possible by a modern light management system with microcontrollers and sensors, which also significantly reduce energy consumption.

Arrived at the office

When you arrive at the office, the ceiling light and desk lamp switch on automatically; their light intensity varies throughout the day. Because depending on the time, the light color can be controlled and adapted to the human biorhythm, for example by combining white and colored light-emitting diodes.

If the sun shines through the window in the afternoon, the lighting system dims the LED lamps on his desk steplessly - or switches them off completely. This means that daylight can also be used optimally in autumn or winter, when less sunlight shines into the window, and the office lighting can be adjusted to the change in sunlight depending on the time of day.

When leaving the room

If the businessman leaves his office for lunch, the light switches off automatically - this also saves electricity.

LED technologies enable companies to significantly reduce electricity and operating costs due to their energy efficiency, high luminous efficacy and infrequent maintenance. The intelligent and automatic dimming or switching off of the light also contributes to this.

A relaxed evening

The businessman is now enjoying his evening after work on the couch at home. He conveniently dims the light of the living room lamps using his smartphone. With the help of the dimmable LED retrofit lamps, which are based on semiconductor technology, it changes the atmosphere quickly and easily depending on the mood. The LEDs are controlled by so-called drivers - here, too, nothing works without semiconductors.

It will probably be a while before the modern lighting technologies arrive in Sri Lanka after the shrimp fisherman has finished his work. The course has been set, however, and light-emitting diodes are continuing their global triumph.

LED technology gives light a new quality because it is more energy-efficient, more climate-friendly and flexibly controllable. The incandescent lamp was once a global technological leap; today, new light sources with bright future prospects have taken their place: LEDs - the light for life.

Sustainably reduce CO2 emissions

The ultra-modern and at the same time environmentally friendly lighting technology is gradually replacing the kerosene lamps that Sri Lanka's fishermen have been using up to now and which are still widespread on the island nation. They consume a lot of fuel.

So far, the 85,000 inland fishermen have used an estimated 30 million liters of kerosene per year - the equivalent of around a hundred fully fueled Airbus A380s - and emitted a total of 75,000 tons of carbon dioxide into the atmosphere.

In addition to the climate-damaging greenhouse gases, the traditional fishing method also endangers the shrimp population. During the day-to-day fishing, fuel runs out again and again and threatens the spawning areas of the crustaceans.

The fact that shrimp fishermen can now switch to innovative lighting technology and protect the sensitive ecosystem from leaking kerosene is thanks to a waterproof and inexpensive LED light that also greatly reduces CO2 emissions. It was developed as part of the “LED - Light-for-you-Initiative”.

Converting the street lighting

In Germany, the electricity consumption for street lighting accounts for an average of almost 40 percent of the total electricity consumption of cities and municipalities. By switching to LED street lighting, cities and municipalities could save up to 80 percent on energy costs compared to conventional lamps. More and more German cities are recognizing the advantages of economical light-emitting diodes - and are therefore converting their street lighting to LEDs.

Reduce energy costs

According to the German Energy Agency (dena), if all office buildings in Germany were to use LED technologies, they could save 500,000,000 euros in electricity costs every year - that's roughly five times the cost of holiday lighting in German living rooms every year Christmas time incurred.

Innovative lighting systems are the prerequisite for this: With a high-voltage resonance controller for lighting systems in the range from 40 to 300 watts, inexpensive so-called LED drivers can be developed. The drivers convert the mains voltage and supply the LED with the required constant direct current. In this way, large lighting areas such as industrial and hall systems, office buildings, streets and public places can be illuminated in an energy-efficient manner.

2015 - the year of light

Promotion of modern lighting technologies

In 2015, the precious form of energy, light, received special media attention worldwide. The United Nations have named the year the "International Year of Light" (IYOL). The initiative aims to promote modern lighting technologies in order to reduce global energy consumption and increase environmental awareness. Infineon is also participating as an expert in energy-efficient LED technologies and light management.

With the initiative of UNESCO, LED technology will continue to gain acceptance worldwide. Infineon is the perfect partner for this: As experts in modern, energy-efficient light-emitting diode technologies and intelligent lighting control, we support companies as well as private users. Our solutions help to protect your wallet, but above all the environment.
