LED lighting allows us to create an atmosphere to our taste, as it allows us to combine infinite colours with multiple levels of intensity, thus adapting to how we feel or even to what we want to do.
On the other hand, the rapid development of mobile technologies has meant that lighting control systems have taken advantage of all this potential and can now offer solutions that are integrated with home automation, building automation or energy control.
Despite the hi number of manufacturers and products, Zigbee technology has been capable of gathering the biggest players around its Zigbee light link protocol and of creating an ecosystem of compatible equipment for domestic and even industrial use. This has meant that pioneering products such as the famous Philips HUE lightbulbs now compete in the market with GE, CREE, WEMO-Belkin, at truly competitive prices and with perfect compatibility.
But if this technology came into our lives through domestic lighting, its huge advantages mean that it is gradually conquering other environments such as, for example, our streets.
In the world of “street lighting” there are compelling factors that make it ideal such as, regulating the light intensity, balancing the contribution of artificial light and natural light, adapting to the presence or absence of people, vehicles, or the type of activity they are illuminating, and all this increasing the lifetime of the equipment and reducing energy consumption.
As this takes place, the need to further develop control systems also increases, and the challenge does not look simple. Cabled systems based on PLC technologies compete with wireless systems in different frequencies.
One standard prevails, DALI, dating back to the year 2.000 and centred on lighting control in a unified way. It is now in a development phase to accommodate new functions such as remote control, new elements such as “Input devices” (sensors) or much more complex functions such as that of balancing the power consumed depending on the peak demands of energy.
Different levels of automation and control depending on the need for control and on the budget, from autonomous control where each ballast is self regulated depending on an integrated logic, to remote systems perfectly integrated in the control systems of cities.
A promising future, reducing the cost of ownership by taking advantage of infrastructures for other purposes as they are the true neural networks of our cities.
At IKOR we currently manufacture more than 200,000 units/month of LED electronics for the headlights of the most important car manufacturers, as well as for the domestic sector. But this does not end here and in the R and D department we are following the development of this technology and its possible application to other fields with great interest.
