An illumination device (100) comprising a light-guide (104) configured to guide light from an entrance end (108) to an exit end (110); a partially transparent partition (106) arranged in said light-guide and configured such that light of a given wave length incident thereupon is partially transmitted and partially reflected, wherein said partially transparent partition (106) extends along at least a portion of said light guide, and divides that portion of the light-guide in first (104a) and second (104b) separated regions; a first light emitting device (102) arranged to incouple light to at least said first region (104a) ; and a second light emitting device (103) arranged to incouple light to at least said second region (104b). An advantage is that uniform illumination can be achieved also in applications where the length of the illumination device is restricted, e.g. for a retro-fit unit. |
