Abstract (en)
A lighting device (10), e.g. for signage applications, includes: - a light-reflective (12a) planar substrate (12) with one or more light radiation sources (14), e.g. LED sources, thereon, - a light-reflective cover layer (18) arranged facing the planar substrate (12), - a light-permeable support structure (16) arranged between the planar substrate (12) and the cover layer (18). The support structure (16) includes opposite end walls (16a) extending between the planar substrate (12) and the cover layer (16), said end walls (16a) providing light emission surfaces of light from at least one light radiation source (14).
