Abstract: A light fixture (100) comprises side wall sections (101, 102) having first surfaces facing towards each other, a light source (103, 104) 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 (105, 106) that constitutes an optical diverter that directs a first part of light emitted by the light source obliquely via a gap (107) between first edges of the side wall sections and a second part of the light obliquely via a gap (108) 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.

Abstract: A light guide (201) comprising a transparent element is presented. The transparent element comprises a first surface (203) for acting as a light-ingress surface and a second surface (204) for acting as a light-egress surface. The second surface comprises elevations (205) for directing a part of the light into directions sideward with respect to a direction in which another and greater part of the light exits the transparent element through the second surface. Each elevation is shaped to provide total internal reflection for a light beam on a first point of the surface of the elevation and refract the reflected light beam on a second point of the surface of the elevation so as to direct the light beam sideward. The sideward directed light enables an observer, who sees the light guide from a small viewing angle, to easily see whether the light is on or off.

Abstract: A device for modifying light distribution comprises a reflector surface (310) whose shape is at least partly based on a shape transformation directed to a geometric auxiliary surface (330). The shape transformation comprises i) division of the geometric auxiliary surface into longitudinal geometric surface segments (314', 315'), ii) displacements of at least some of the surface segments sideward so as to achieve a desired shape, and iii) addition of geometric connection-surfaces (316) between surface segments that are at least partly separated from each other by the displacements so as to form a stepped geometric surface corresponding to at least a part of the reflector surface. The geometric auxiliary surface can be select- ed according to a desired intensity distribution within an illumination pattern formable on a planar surface, whereas the shape obtained with the shape transformation can be selected according to the desired shape of the illumination pattern.

Abstract: An optical system comprises one or more lens elements (102, 103) for modifying a light distribution pattern, support elements (106) for securing the lens elements to a body structure, and elongated seal sections (108, 109) for constituting elongated sealing contact areas with the lens elements and with the body structure.

Abstract: A light guide (201) comprising a transparent element (202) is presented. The transparent element comprises an optically active section (203) forming a cavity for a light source and shaped to modify the light distribution pattern of the light source, and at least one channel (205) beginning from the cavity. Each channel comprises a punctureable sheet (210) of the transparent material closing the channel so that puncturing the punctureable sheet opens, through the channel, a passage between the cavity and ambient of the light guide. When the sheet is left intact, i.e. not punctured, the above-described light guide is suitable for applications where hermetic sealing of the cavity is needed. On the other hand, by puncturing the sheet, the light guide can be made suitable for applications where pressure balancing and/or ventilation of the cavity are/is needed.

Abstract: An optical device (201 ) comprises a center section (202) having a lens portion for modifying distribution of a first part of light emitted by a light source, and a peripheral section (203) surrounding the center section and comprising a conical surface (205) for modifying distribution of a second part of the light emitted by the light source. The conical surface comprises ridges (206) where total internal reflection takes place when a light beam arrives from the light source at one of side surfaces of each ridge, and surface penetration takes place when the reflected light beam arrives at the other side surface of the ridge under consideration. Thus, the conical surface acts both as a reflective surface and as a refractive surface for achieving a desired light distribution pattern.
