Abstract:
To provide homogeneity of an illumination and/or a signal device, particularly relating to an automobile field, at a low cost.SOLUTION: At least two LED light sources 16 are individually powered and activated, and they each face light input walls 32', 32'' of corresponding light guide parts 28. The light guide part 28 emits light of the LED light source 16 from a front wall 44 via at least two individual illumination parts 36, 40, and has a diffuser element positioned at a rear wall 52 opposite to the front wall 44. At least one reflection element 56 connected to each light guide part 28 is directly opposed to each diffuser element so that the light can be reflected toward the front wall 44. The light guide part 28 is mechanically and optically separated by a barrier element 68. The barrier element 68 prevents the light from passing between the light guide parts in at least one inner wall 64.SELECTED DRAWING: Figure 1
