Abstract | The invention relates to an optical module comprising two or more segments positioned around an axis of symmetry of the module. Each segment includes a light collimating structure for providing a predefined light distribution of light exiting the module and a light source assembled in a cavity within the light collimating structure. The center of the cavity coincides with the optical axis of the light collimating structure and is at a distance (d) from the axis of symmetry of the module. Including two or more segments where each segment comprises its own light source allows obtaining higher lumen output compared to prior art luminaires having only one light source while arranging the segments so that the center of each cavity coincides with the optical axis of the collimating structure of the segment allows preserving narrow beamwidth collimation of the light exiting the module. |
