What is the history of light?

Since the beginning of mankind, sunlight has played an important role in the life of people. We give us warmth, light and energy that we can use.

But only with that invention the electricity new opportunities have been created to use the light.

Since then, the technology has continued to develop, and today we have LED lights that are superior in many ways.

The history of sunlight.

The sunlight is the origin of all light on earth. It is a mixture of different wavelengths of the electromagnetic spectrum that are broadcast by the sun. Sunlight has always been important for us humans.

We gave us warmth that we need to survive and light that shows us the way and enables us to see things. The first attempts to use the sunlight go back to the 7th century BC. The Babylonians and the Assyrians used glass lenses to bundle the sunlight and make fire.

In ancient Greece, the scientists used Archimedes and Pythagora's mirrors to reflect on the sunlight and make fire. The sun was the only light source for a long time.

Man has also been to the over time Change of day This also developed- the soothing or activating effect of the light also developed with the help of color temperature and brightness. 

What does HCL mean?

Under the term Human Centric Lighting such findings are mainly used to constantly improve in the technology of light. Light changes the temperature and intensity Parallel to the daylight.

It is said that people are most active between 6 a.m. and 6 p.m. bluish appears. Blue light activates the mind and promotes thus the motivation and concentration of humans.

Orange Light, which occurs in the course of the period between 7 p.m. and 0 a.m. and is very low of the light intensity, makes people more likely tired, and calls for the brain to get into the Deep sleep to go.

Misuse of the fire.

While the fire used to be only for a long time Cook, as Heat source, as Fire toboggan or the Protection before dangerous Tales used in caves and rooms, the fire was used over time using torches, gravel pan or candles, for example, such as the development of agriculture or the invention of the Steam engine and the Mirror telescopesto illuminate.

In the Middle Ages, glass windows were then developed that capture the sunlight in churches and buildings and guide them to the interior. In the 19th century, gas lighting was invented, which turned the night into day and improved the quality of life.

The discovery of the electricity Was a milestone in the history of lighting.

In 1800 Alessandro Volta discovered electricity by constructing a battery from a copper and zinc plate. A few years later, Michael Faraday invented the generator, who was able to produce electricity in larger quantities. 

The first light bulb.

The first light bulb was about 1879 from Thomas Edison invented. It consisted of a light bulb with a carbon thread that was heated at the flow of electricity and thereby gave up light. However, these light bulbs were inefficient and now had a limited lifespan.

As an entrepreneur, however, Edison not only sold lamps, but also electricity: a very large performance of it was the electrification of the city of New York in order to make lights on the streets shine- so more use for the glass lanterns could also be obtained.

The development of the fluorescent lamp.

In the 1930 Years became the Fluorescent lamp invented. It is much more efficient than that Light lamp And has a longer lifespan. Luminous lamps work by unloading electrons in a gas, which creates ultraviolet radiation, which is converted into visible light.

In summary, it can be said that the US American inventor made the inventions and discoveries competitive. Even today, the E with the threads and versions (E27 and E14) stands for "Edison thread“.

The LED revolution.

In addition to the temperature beams and discharge lamps, the LED lights were created over time. The LED-Technology (Light Emitting Diode) was developed in the 1960s.

However, the first LED lights were only available in red, green and yellow and had a low luminosity. It was only in the 1990s that LED lights were developed in white, which had high luminosity and efficiency.

Today LED lights have become indispensable in many areas of lighting technology. One of the most important advantages of LED lights is yours Energy efficiency. Compared to incandescent lamps, LED lights only consume a fraction of energy and have a much longer life. Another important advantage of LED lights is yours durability.

In contrast to incandescent lamps, which can easily break due to the hot glow threads, LED lights are very much robust And can also be used easily for vibrations or vibrations.

This makes them ideal for use in the automobile- and Aerospace industry As well as in many other areas where the durability and reliability are of crucial importance.

The LED lights are also very versatile can be used. You can in a variety of Colors and Brightness are therefore manufactured and suitable for a variety of applications. From the lighting of streets, buildings and parks to signal and warning lights in vehicles or machines- LED lights can be found everywhere.

Another advantage of the LED lights is their environmental friendliness. Compared to conventional lights, LED lights contain no toxic or harmful substances such as mercury or lead and have a much lower Carbon.

This makes it an environmentally friendly alternative that can help to CO2 emissions to reduce and protect the environment. Another advantage of the LED lights is that the LEDs are particularly flat to integrate them perfectly in LED strips, ceiling lights, wall lights or many other types of light.

LED lighting has been an integral part of nowadays and in the future.

The Oled Technology So far only used for electrical appliances, as with a TV. 

The future of lighting.

The development of LED lights has fundamentally changed the way we use the light. But the technology does not stand still, and there are already new developments that the Future the lighting will change further. A promising technology are the OLED lights (Organic Light Emitting Diodes).

These lights are made of organic materials (carbon) that emit light when using electricity. Compared to LED lights, OLEDs can be used even more efficiently and flexibly because they can be cut to different shapes and sizes.

Another interesting development are Li-fi lights (Light Fidelity). These use light as a transmission medium for data and thus enable faster and secure data transmission than conventional WLAN networks.

The conclusion on the process of creation of the light.

The history of sunlight and the lighting has gone through a long development, that of the discovery of the electricity up to revolution the LED technology suffices.

The LED lights have proven to be one of the most important and versatile forms of lighting technology and offer a variety of advantages, including Energy efficiency, durability, Environmental and versatility.

But the technology is not quiet, and there are already new developments that will continue to change the future of lighting.
