Aircraft LEDs offer savings

ES Aug13 Pg05 to 10 News AercoAerco is offering an LED replacement for the 387 aviation incandescent lamp. Made by CML, the lamps are said to offer significant improvement in terms of life, energy consumption, reliability and operating cost.

The Nichia LEDs used in the new 387 LED lamps consume two and half times less power than filament lamps and have an anticipated life of 50,000 hours compared to 7,000 hours. In practice, the life of a filament lamp used on aircraft can be as low as 1,000 to 2,000 hours because of the constant vibration which ages lamps. This means that LEDs can last up to 50 times longer than filament lamps. Further benefits relate to the waste heat generated by standard lamps. Typical front panel temperatures using an LED are 25.5°C compared to 35.4°C using a traditional lamp.

The 387 LED is a direct replacement to the standard lamp and requires no changes in fixing. Only one part number is required to replace both cockpit and cabin lamps. The 387 LED lamps have been tested on aircraft and flight simulators, carry FAA PMA approval and have been shock and vibration testing in accordance with RTCA/DO-160Fd.
