AIM Altitude has developed an autonomous lighting dimmer (ALD) system that will enhance the ambience of premium cabins, allowing LED feature lighting to be independently controlled without the need to
connect to the aircraft’s IFE system or cabin mood lighting system.
The ALD is a single channel, single colour, 28v DC dimmer. It is able to power and control up to 2.5 amps (70 watts) of DC LED lights. This is sufficient for up to 12 metres of AIM Altitude’s white LED strip lights, with no connection to the aircraft lighting system.
The ALD system can accept discrete on/off inputs or can be used with AIM Altitude’s Light Sensor to automatically follow the intensity of the aircraft manufacturers’ cabin lighting system. ALDs can also be used to control autonomous feature lights in first and business class monuments and in illuminated bulkhead feature panels. The ALD provides user-definable controlled dimming, with over 4,500 incremental steps.
AIM Altitude says that the ALD is unique in having electromagnetic emissions that meet the stringent requirements of Boeing 787, Airbus A380 and A350 aircraft for LED cabin lighting in line-fit applications. The ALD is currently qualified for monument, bulkhead feature panel and premium seat applications in the Boeing 787-8 and 787-9, for bulkhead feature panel and seat applications in Airbus A380 aircraft, and for premium seat applications in Airbus A350 aircraft.
“AIM designed and developed the very first mood lighting to be used on passenger aircraft,” said John Heath, group design and technical director at AIM Altitude. “It has now become in important way for airlines to provide differentiation and to set the atmosphere for their passengers. Being autonomous, our ALD system provides airlines with great flexibility to add ambience to specific areas of the aircraft and to manage the cabin environment as required.”
AIM submitted a UK patent application for the ALD in 2014 and has also applied for protection in the rest of the EU and the USA.
