Tideland Signal, the specialist in marine lanterns and other aids to navigation, has won a contract from Sumitomo Corporation to supply solar powered warning lights to mark towers on the Sidi Krir electricity transmission line from Cairo to Alexandria. The light chosen by Sumitomo for this important project is Tideland’s SolaLED-155, a solar-powered LED lantern, which has demonstrated its long-life, low-maintenance reliability in the harshest marine environments around the world. The new transmission line will be carried on a total of 540 towers or pylons, of which 49 will be marked by a red SolaLED-155, particularly near safety-critical locations, such as airports.
Tideland’s SolaLED-155 incorporates an integral solar panel that charges a lead acid battery, giving a range of 3NM, coupled with minimal maintenance requirements and a service life of seven years on station in the most demanding environments. It is even designed to withstand immersion in salt water. Long-life LEDs and high-integrity electronics housed in a tough UV-resistant polycarbonate enclosure ensure that the lantern does not need to be opened during its service life. A high-efficiency DC to DC converter is incorporated, providing virtually constant luminous output under a wide range of input power conditions. LED service life is calculated at 100,000 hours.
The lantern is available in a wide range of colours and offers sophisticated control systems, including a choice of three programming modes. It can be factory-programmed to the required setting or, alternatively, the user can programme it either by radio remote controller or from a laptop using Tideland’s LEDCOMM program. In addition to code setting, the LEDCOMM program offers the user visual reporting of the state of battery charge and the ability to set preferred levels for power/intensity, photo cell switching and low voltage disconnect/activation.
