Abstract
A lighting arrangement includes a light source configured for emitting light; a first reflector configured for collimating a first portion of the light emitted by the light source around a main light emission direction (D); and a second reflector arranged opposite to the light source. The second reflector is configured for reflecting a second portion of the light emitted by the light source back towards the light source for being diffusely reflected from the light source.
Claims13
A lighting device comprising at least one lighting arrangement, wherein the at least one lighting arrangement includes:
- a light source configured for emitting light;
- a first reflector having a parabolic shape or an at least partially spherical shape and defining a light collimation space and configured for collimating a first portion of the light, which is emitted by the light source into the light collimation space, around a main light emission direction;
- and
- a second reflector arranged within the light collimation space opposite to the light source and configured for reflecting a second portion of the light emitted by the light source back towards the light source for being diffusely reflected from the light source, wherein the second reflector is arranged on a light emission axis, which is aligned with the main light emission direction, and wherein the second reflector has rotational symmetry around the light emission axis;
- wherein the light source is supported by a mounting structure, which is arranged outside the light collimation space, wherein the light source is located in an opening of the first reflector, and wherein the light source is located substantially at a position where the light emission axis would intersect with the parabolic shape or with the at least partially spherical shape of the first reflector in the absence of the opening in the first reflector;
- and
- wherein the lighting device is an exterior aircraft lighting device or an interior aircraft lighting device.
