ILED Lyra 3/5 NM Lantern

Overview

The ILED Lyra is used as a subsidiary marine obstruction light as required by IALA’s O-139 and DECC (UK Department of Energy and Climate Change) regulations, amongst others. Both IALA and DECC regulations require the use of subsidiary lights to mark the extremities of (fixed) obstructions at sea that could pose a threat to navigation. To that end the Lyra is used as an addition to the ILED Dorado Main & Secondary lights and completes IMT’s portfolio of NavAid products. The ATEX/IECEx certified LED driver can be programmed to deliver the required light-output and Morse Code – “U”  making the Lyra a very versatile solution that can be adapted to almost any set of regulations and conditions.

The ILED Lyra has been designed to withstand the harsh conditions of a marine environment. The body is made of a very corrosion resistant anodized aluminium alloy (marine grade). The excellent thermal conductivity of aluminium allows for efficient heat management of the LEDs ensuring the longest possible service life. The lens is made of toughened borosilicate glass, while the driver is housed in a glass fiber reinforced polyester junction box. The assembly is mounted on a stainless steel AISI 316L mounting bracket.

As with all IMT products, the ILED Lyra was designed to require an absolute minimum of maintenance and manufactured as a sealed unit, which keeps all contaminants and corrosive influences away from sensitive electronics, combined with the ATEX/IECEx Ex e certification mean that only an occasional visual inspection is required, while smart design, excellent heat management and the use of highest grade materials and components ensure the longest possible life expectancy. The result is lower maintenance costs, increased safety and a very
low total cost of ownership.

The ILED Lyra with the flash frequency morse code – "U" integrates seamlessly with an IMT NavAid system and is fully compatible with the Master Control Card. The Master Control Card allows for synchronization with the other marine lanterns with the morse code – "U" in the system (as required by regulations) but also communicates with the lanterns and receives feedback on their current status. The intelligent circuits in the LED driver keep track of the number of hours the fixture has been operating and automatically adjust for the gradual degradation over time that all LEDs are subject to, maintaining a constant light output over its full service life.
