The story of light guides you through centuries of human invention and technological innovation. Observation of nature brought fire, a source of light and heat that triggered an avalanche of discoveries and developments that will change society once and for all. Now, when the climate crisis is a real threat, you must look for solutions that not only make your life easier but also support the planet.
The invention of a beeswax candle: Lighten up the “dark ages”
The breakthrough came with the invention of a beeswax candle. It made the process of turning the light source on and off much easier, and it was also a handy little object. Everything indicates that already in the 2nd century BC. Your ancestors enjoyed the first candles they made. Due to the expensive material, they were used during ceremonies and religious holidays. In the 10th century, candles became more common due to a cheaper substitute. Over the centuries, many arrangements have been created to brighten up the interior. This is how the first infused candles, chandeliers, and sconces appeared.
LED technology as an alternative to traditional light sources
Today, the so-called LED bulbs look like traditional bulbs. The light here, however, is obtained in a completely different way, using light-emitting diodes placed in a special housing. Inside, there is also an optical system and a driver. Thanks to this you can control the amplification, dispersion, and correct direction of the light beam.
History of LED technology
The beginnings of LED lamps date back to when the phenomenon of electroluminescence was discovered more than 100 years ago. However, they were practically used in the 1950s, when infrared was obtained from gallium arsenide and other semiconductors. The first LED is a yellow LED, invented in 1972. This produces a much more robust light. The breakthrough happened with the development of the blue LED. The inventors Shuji Nakamura, Isamu Akasaki, and Hiroshi Amanoi received the 2014 Nobel Prize in Physics.
In 2009, the first LED bulbs appeared on the market. Nonetheless, they were heavy and massive and definitely too costly. Technological innovations have given the product a much more accessible form. LEDs can now glow many colors, have full-spectrum light, and are much cheaper than their prototypes. Today, LED technology accounts for approximately 50% of the global lighting market. It is much more efficient than traditional light bulbs. It consumes approximately 80% less energy and is able to glow up to 15 times longer.
The purchase of LED technology is not only a profitable investment but also an investment for the future, improving the quality of work and home operation.
