FlexSol was asked to design solar warning lights for the city of Utrecht in the Netherlands. Also, FlexSol provided the solar modules to power the LED lights. These solar warning lights are part of an innovative pedestrian crossing. To explain, speeds sensors (radar) on the light poles detect the speeds of approaching vehicles. When the sensors detect speeds of 20km/h or more the color of the LED rings will switch from blue to a flashing orange.
Also, the solar-powered light poles communicate with the crossing, which will subsequently light up. Both the flashing lights and the illuminated crossing will warn approaching cars. As a result, pedestrians can now safely cross the streets in this Dutch neighborhood.
Besides the speed sensors, other sensors are also attached to the light poles. Because of this, the solar-powered light poles are also smart poles which are perfect for smart cities.
