GVE - LED-based Medium Intensity AOLs (covered under patent) using special long-lasting, ultra high intensityInP Technology LEDs. These LED aviation lights are characterised by extremely long life (100,000 hours, or 11years continuous burning), and low per consumption.The solid-state LED construction utilises an omnidirectional matrix of extremely high brightness LEDs which provide lightintensities comparable to the existing aviation lights. These LED units are maintenance free, and are a “fit-and-forget” solutionsince they never require replacement. While the initial capital cost of these LED Aviation Lights is lower than that ofconventional xenon tube type medium intensity lights (which conform to ICAO requirements), their payback period is alsoextremely short.The latest InP technology LEDs are used in the construction of these LED lights. InP technology LEDs are specified theworld over for outdoor applications as they have greater ability to withstand high temperature and high humidity conditions,as well as ultraviolet radiation. The circuit design – coupled with the choice of the LEDs used— provides high reliability.Furthermore, the LEDs in the unit are configured in multiple series-parallel circuits, and as such one can considerthat each unit is backed up by several standby units. Thus, fail-safe redundancy is built in; even if one circuit fails, the othercircuits will still provide a visible indication.
