When we talk about smart cities that provide high-quality and eco-friendly services, we don't necessarily need to consider the radical transformation and huge investments of megacities.Today, there are some simple solutions and a high level of technology that can create energy efficient, smart and high-quality lighting infrastructure through sustainable investments, even in small towns.
Virtual midnight computing is based on a mechanism that can be applied to public lights and, more broadly, outdoor lamps, allowing programming to reduce the light flux when you don't need the lamps to run at full capacity all the time.For example, during the central hours of the night, in areas with low vehicle and pedestrian traffic, a reduction in light flux will keep lighting levels within safe standards while saving energy.With hundreds or even thousands of street lights, the cost savings can become significant.
The virtual midnight device calculates the average of the time between when the device is on (sunset) and when it is off (sunrise).From this hypothetical value, the lights can be dimmed as needed and as applicable.The system can also automatically adjust seasonal switching times.
This type of device, applied to LED lighting systems, results in considerable energy savings with older technology.How much money can you save?For example, replacing an LED street lamp with a 150-watt high-voltage sodium source can save up to 30% of your energy (for 11 hours at full load).Saving up to 52 percent with virtual midnight.In fact, the luminaire operates at full power for 4 hours and at 50% power for 7 hours.
It is worth noting that the initial system setup - if necessary - can be easily customized from the dashboard.Therefore, the operation and maintenance of the system does not need to spend too much energy and cost.
