Abstract: A light guide element (201) for modifying a light distribution pattern of a light source (202) is presented. The light source radiates first light beams to a first quarter-space and second light beams to a second quarter-space, where the first and second quarter-spaces are defined by mutually perpendicular spatial planes and one of the spatial planes constitutes a planar boundary between the first and second quarter-spaces. The light guide element includes transparent material (207) on a route of the first light beams for modifying the light distribution pattern of the first light beams and a reflective surface (208) for reflecting at least a part of the second light beams to the first quarter-space. A surface of solid material on a route of the second light beams includes grooves for spreading the light distribution pattern of the second light beams in the direction of the section line between the spatial planes.

Abstract: An optical device (101) for modifying a light distribution is made of transparent material and comprises a front wall (102) constituting a front portion (103), a coupling portion (104) for connecting to a light source system, and side walls (105, 106) between the coupling portion and the front portion. The front wall is configured to let through a first part of light emitted by the light source, and the side walls are configured to let through a second part of the light. The side walls have grooves (107) that refract at least 80% of the second part of the light obliquely rearwards with respect to a direction (d) from the coupling portion to the front portion. Thus, the Optical device can be used for illuminating both a floor and a ceiling so that light emitted to unwanted directions and potentially causing glare can be kept at a low level.

Abstract: A light fixture includes side wall sections having first surfaces facing towards each other, a light source on the first surface of at least one of the side wall sections and positioned so that a maximum intensity direction of a light distribution pattern of the light source is towards the other side wall section, and a lens section that constitutes an optical diverter that directs a first part of light emitted by the light source obliquely via a gap between first edges of the side wall sections and a second part of the light obliquely via a gap between second edges of the side wall sections. Thus, the light fixture can illuminate both a floor and a ceiling so that light emitted to unwanted directions and potentially causing unwanted bright spots and/or glare can be kept at a low level.
