Patent attributes
An illuminating device has a planar, elongate lighting unit and a profile-shaped carrier component. The lighting unit can be fixed to the carrier component. The lighting unit has a profile element which is permeable to light and has a cross-sectional shape which is U-shaped in some portions, opposing limbs of the U-shaped cross-sectional shape extend substantially in the thickness direction of the lighting unit, and an inner region of the profile element is formed with an opening formed between the limbs by the U-shaped cross-sectional shape. The lighting unit has a planar base part which is arranged in the region of the opening and is coupled to the profile element. The profile element is formed by a material which offers less resistance to a deformation than a second material by which the planar base part is formed. In the inner region, a light-generation device is arranged in this case.
