| 摘要： | The roundabout at the south end of Andornaktalya village was completed in the summer of 2018 as part of the construction of express road M25 in north-east Hungary. Experiences gained since it was commissioned showed that the intersection needed good lighting for the safety of drivers and cyclists alike. A solar panel lighting system was installed which has a storage capacity sufficient to cover the energy needs of the functional lighting all year round. Power for the lighting is provided using solar panels to supply rechargeable batteries which provide power to the lights. The core feature of this solution is that light is provided in the intersection using candelabra-style lights on top of the poles installed on the roundabout island and also at bicycle crossings (see aerial image). This means that those entering the intersection will not encounter any separate functional lighting columns. In other words, only those lights needed for the motorist/cyclist will be powered up from a low level to full strength as vehicles approach. This custom-developed functional lighting works independently of the grid. The LED lamps provide a light level of 10 lux by default in the roundabout and 15 lux at the cycle crossing. |
