The reflective surface is located opposite to the exit surface to extend in the main scanning direction and includes a plurality of light reflecting patterns formed to reflect the incident light toward the exit surface. The light reflecting patterns have an oval hemispherical shape rising toward the exit surface and a first diameter of the oval hemispherical shape along a sub-scanning direction is equal to or longer than a second diameter thereof along the main scanning direction. The light reflecting patterns are formed to vary the ratio of the first diameter to the height of the oval hemispherical shape depending upon the location on the reflective surface in the main scanning direction.

Abstract: A lighting system including modules containing LEDs or other electroluminescent devices and loosely constrained magnetic structures at least partially contained within cavities in the module substrate that are connected to fixtures under magnetic force. The loosely constrained magnetic structures accommodate mechanical variations in the system and provide a method to connect modules mechanically, electrically and thermally to different fixtures or positions in fixtures without tools. The relatively short distance separating magnetic structures provides high connection forces with the use of relatively small magnets. Magnets and electrical contacts are not located directly between the LED subassembly and the fixture, which provides higher thermal conductivity pathways to remove heat from the LEDs. Biasing members may be used to increase thermal contact. Magnetic structures may, but are not required, to conduct electricity.
