Past, Present and Future of LED Lights
As it is known, LED lights reduce energy consumption in our homes, workplaces and in every environment where they are used, and they are the lights that provide us with financial benefits. So, how did LED lights enter our lives and how did they develop, let's examine them a little bit;

First LED
More than a century has passed since British engineer H. J. Round first discovered the phenomenon of electroluminescence in 1927, a breakthrough that directly led to Oleg Losev inventing the first light-emitting diode (LED).

Unlike traditional incandescent bulbs, LED bulbs do not use a filament to produce their light. Instead, they are illuminated by the movement of electrons in a semiconductor material. This means they can emit the same brightness as a conventional light bulb, but use only a fraction of the power. They also last many times longer than incandescent bulbs because they have no filaments to burn, making them cost-effective and energy efficient.

Initially, LED bulbs were only used in specialized electronics and laboratory equipment, as the light they produced was unsuitable for other uses. Also, the cost of producing them was too high to be commercially viable.

As research into LED technology continued, they became cheaper to manufacture and the quality of the light they emit was improved. In 1962, an American engineer named Nick Holonyak created the first LED to produce visible light suitable for a wide variety of uses, and LED light technology took a huge leap forward.

By the 1970s, some companies were producing LED light bulbs and would use some form of LED lights in the near future in calculators, clocks, radios and telephones. These are the core technology used in today's big-screen, ultra-high-definition televisions and the next generation of domestic and commercial lighting.

Blue Light LED Bulbs
Such an application has only been possible in recent years. Because after its invention, only red, green and yellow LED bulbs could be produced for a long time, and although it was suitable for many uses, it was not suitable for lighting our homes and workplaces.

It dates back to the 1990s when scientists Isamu Akasaki, Hiroshi Amano and Shuji Nakamura invented the blue light LED and with it the ability to create white LED light. (Because white light is not possible without the full spectrum of light). The achievement was revolutionary and the three scientists were awarded the 2014 Nobel Prize in Physics for their achievements.

The transition from blue light to white light LED bulbs was only a short jump, but the next challenge from there was developing the technology for commercial use. Companies such as Philips invested funds in the development of LED lighting in the late 2000s, and by 2010 the technology had begun to become common.

A wide variety of LED bulbs are now available, from small surgical lights to high-power projectors. They are even used as part of some cancer treatments. With the development of technology, the cost and energy efficiency of light bulbs will continue to improve.

The Future of LED Lights
The discovery of blue-light LED bulbs has unlocked the true potential of LED lighting. LED lights can change the lives of 1.3 billion people worldwide who live without electricity. Combined with solar power, LED bulbs can provide inexpensive, sustainable light sources to places without a grid. Some charities have started to distribute sunlight to Countries where they do not have access to electricity.

The potential of LED technology is only limited by our imagination. For many years, LED bulbs were used mainly as 'indicators' (such as power lamps in electronic devices). Blue-light LED bulbs have changed all that, and LED lighting is now used almost everywhere. It may take some time before we realize the full potential of LED lights, but it should be known to everyone that good progress has been made and good progress has been made.
