Abstract (en)

An automotive lamp (10), which may be used e.g. as a retrofit lamp, comprises a lamp body (12, 161, 162) having opposed concave lateral recesses (221, 222) and LED light sources (141, 142) at the bottom surfaces (141a, 142a) of the lateral recesses (221, 222). Therefore, light radiation is both emitted directly and partly reflected by the peripheral surfaces (241a-d, 242a-d) of the recesses (221, 222). The aforesaid peripheral surfaces comprise a first longitudinal face (241a, 242a) which is smaller than a second longitudinal face (241b, 242b) opposed thereto. A LED linear array (141, 142) is placed between said longitudinal faces closer to the second face (241b, 242b) than to the first face (241a, 242a). The peripheral surfaces also comprise a first (241c, 242c) and a second (241d, 242d) transversal faces, with the first transversal face (241c, 242c) towards the front end being smaller than the surface area of the second transversal face (241d, 242d).
