Lighting strip for an aircraft interior and aircraft interior equipment with a plurality of lighting strips

摘要

A lighting strip for an aircraft interior is provided. The lighting strip has a connection for a network voltage, a rectifier for rectifying the network voltage into a power supply voltage, and a circuit board extending along a longitudinal extension of the lighting strip. Multiple LEDs are arranged on the circuit board and powered by the power supply voltage. A controllable current sink arrangement, having multiple individual sink devices connected electrically in parallel with one another, is provided for converting electrical energy transported via the connection into heat. The individual sink devices are distributed on the circuit board along the longitudinal extension of the circuit board. The sink devices are controlled by a control apparatus independently from the operative conditions of the LEDs to provide a homogenously distributed thermal profile of the lighting strip.
