3results about "General lighting" patented technology

A cabin illumination device is provided on a wall surface of a cabin of a vehicle and illuminates the cabin and includes: a light source disposed to emit light away from the wall surface; and a reflective member disposed to intersect a light axis of light emitted by the light source. The reflective member includes a first protruded surface disposed to intersect the light axis of the light source, and a portion of the reflective member is sloped downward in a direction away from an intersection of the light axis and the first protruded surface.

A surface-mounted luminaire (2) for a passenger cabin (4) of a passenger aircraft (6) comprises a layered, planar base carrier (8), one flat side (10a) of which is a light-emitting side (12) and a plurality of LEDs (14) which are arranged planarly on the light-emitting side (12) of the base carrier (8), wherein a plurality of the LEDs (14) are accent LEDs (LA) which, in operation (B), produce colored light of a selectable color and which are planarly distributed over the base carrier (8), wherein at least two of the accent LEDs (LA) are individually adjustable with respect to a color and brightness of the light they produce in operation (B), wherein a plurality of the LEDs (14) are basic LEDs (LG) which, in operation, produce white light and which are planar distributed over the base carrier (8), wherein at least two of the basic LEDs (LG) are only jointly adjustable with respect to the brightness of the light they produce in operation (B).and wherein a large number of the LEDs (14) in operation (B) are white light-producing emergency LEDs (LN) which are distributed over the surface of the base carrier (8), wherein all emergency LEDs (LN) can be supplied with energy independently of the accent LEDs (LA) and base LEDs (LG).

The invention relates to a flat panel luminaire (2) for a passenger cabin (4) of a passenger aircraft (6), the luminaire comprising a base carrier (8) which extends over the surface in a layered manner, one flat side (10a) of which forms a light-emitting side (12), and a plurality of LEDs (14) which are distributed over the base carrier (8) and arranged thereon on its light-emitting side (12), wherein a plurality of the LEDs (14) are accent LEDs (LA) which, during operation (B), generate coloured light of selectable colour and are distributed over the surface of the base carrier (8), wherein at least two of the accent LEDs (LA) can be individually adjusted in terms of both the colour and the brightness of the light generated by them during operation (B), wherein a plurality of the LEDs (14) are base LEDs (LG) which, during operation, generate white light and are distributed over the surface of the base carrier (8), wherein at least two of the base LEDs (LG) can only be jointly adjusted in terms of the brightness of the light generated by them during operation (B), and wherein a plurality of the LEDs (14) are emergency LEDs (LN) which, during operation (B), generate white light and are distributed over the surface of the base carrier (8), wherein all emergency LEDs (LN) can be supplied with power independently of the accent LEDs (LA) and base LEDs (LG).
