LIGHT GUIDE, PATTERNED LIGHT EMITTING DIODE DEVICE, ILLUMINATION SYSTEM AND METHOD OF GENERATING THE LIGHT GUIDE OR PATTERNED LIGHT EMITTING DIODE DEVICE |
摘要 |
The invention relates to a light guide (10), a patterned light emitting diode device, to an illumination system (100) and to a method of generating a light guide and/or patterned light emitting diode device. The light guide comprising a light-emitting window (20), a rear wall (22) situated opposite said light-emitting window, edge walls (24) extending between the light-emitting window and the rear wall. The light guide further comprises a deformable substantially transparent layer (30) arranged between a light-reflective layer (40) and the rear wall of the light guide. The light-reflective layer comprises a pattern (42) constituted of local deformations (42A, 42B) of the light-reflective layer for scattering impinging light.
