Title: A LIGHTING MODULE, A LIGHTING SYSTEM AND A METHOD OF LIGHTING
Abstract:
The invention provides a lighting module (100) which comprises a plurality of first light sources (101) configured for emitting first light (102) in a first predetermined direction, and at least one second light source (103) configured for emitting second light (104). The lighting module (100) further comprises a light guide (105) which comprises at least one light in-coupling portion (106) to couple at least part of the second light (104) into the light guide (105), and a plurality of light out-coupling portions (107) to couple at least part of the second light (104) out of the light guide (105). The light guide (105) is arranged to guide the second light (104) coupled into the light guide (105) at the at least one light in- coupling portion (106) via total internal reflection (108) to the plurality of light out-coupling portions (107) for generating out-coupled light in a second predetermined direction. The light guide (105) is mechanically coupled to and extends along the plurality of first light sources (101). The light out-coupling portions (107) cover a larger first area (109) than a second area (110) covered by the plurality of first light sources (101). A total luminous flux generated by the at least one second light source (103) is lower than a total luminous flux generated by the plurality of the first light sources (101). The first predetermined direction and the second predetermined direction at least partly overlap.
