“Green” LEDs – the future of street lighting.

People have used street lighting for over 300 years. With the scientific and technological progress, the design of the luminaires has changed constantly: from candles and kerosene lamps to modern LEDs. And if at first only some cities were illuminated, now it is difficult to find a settlement without the usual light pillars with street lamps. A large number of metropolises appeared, the number of inhabitants totaling tens of millions of people, and the population of the planet exceeded 7 billi ...

The sunset of the luminescent lamps era.

Luminescence. A curious effect caused by gas when electricity passes through it, as M. Lomonosov also noticed many years ago. Later, many well-known scientists were involved in this: Heinrich Geisler, Nikola Tesla, Thomas Edison. They all worked to obtain another light source and contributed to its development. Only Edmund Germer in 1926 proposed the design of a fluorescent lamp in the way we know it today. The principle of its operation is quite simple: a glass tube filled with inert gas and ...

DALI or 0-10 protocols. What is the difference?

The idea of ​​controlling the intensity of the light in the room appeared simultaneously with the lighting itself and this problem was solved in part in different ways. While candles were being used - it was controlled by the size and number of candles, the kerosene lamps - by changing the length of the wick. When incandescent bulbs took the place of candles, it turned out that the problem of controlling the intensity of light remained. Of course, there were lamps of different capacities and a c ...

NB-IoT – technology for business solutions.

Why intelligent things need their Internet. Since the emergence of the IoT (Internet of Things) idea, there has been a communication problem between devices, namely wireless communication. Indeed, the concept of IoT involves a connection between billions of devices and it is simply unthinkable to connect them with cables. To this problem was not given less attention than the development of devices itself. For this, many problems have to be solved, both hardware and software. Traditional metho ...

Lamps for SmartLight.

As we found out in the previous article (Time to change your light), replacing street lighting lamps with LED lights is not only a sound investment, but also a choice of companies that care about consumer comfort, their own image and the environment. Moreover, taking into account the European vector of development and legislative initiatives of the European Union, such transition is inevitable and will take place in the near future. In the European Union, the idea of using LEDs as a source of ...

Time to change your light.

What happened on the LED lighting market in the beginning of the 21st century can only be called a light revolution. Who would have thought that a semiconductor diode, born in the 20s of the last century, discovered by chance and working on completely different principles than classical sources of light, will turn the lighting industry over and become a competitor of traditional High Pressure Sodium (HPS) lamps and will force it out of the market. And all this will happen in 10 years! Whi ...
