Abstract: The invention relates to a LED lamp comprising a gear column which is connected, at its first end, to a lamp cap and, at its other end, to a substrate. Said substrate comprises a number of LEDs. According to the invention, said substrate is provided with a regular polyhedron of at least four planes, said planes comprising at least one LED having a luminous flux of at least 5 lm. The gear column also comprises heat-dissipating means which interconnect the substrate and the lamp cap. A continuous and regular illumination with a high luminous flux can be obtained using a LED lamp of this type.

Abstract: A headlamp (2; 3) of a vehicle (1) has a light source (4; 5) comprising a plurality of opto-electronic elements (11; 12; 13; 14), preferably light-emitting diodes (LED's). At least one of these opto-electronic elements (11; 12; 13; 14) has, in operation, a luminous flux of 5 lm or higher. According to the invention, the spectral characteristic of the light beam (6, 6null; 7, 7null) generated by the light source (4; 5) depends upon the position in the light beam (6, 6null; 7, 7null). Preferably, the light source (4; 5) comprises opto-electronic elements (11; 12; 13; 14) only. The light beam comprises at least two light beam segments (6, 6null; 7, 7null) having essentially different spectral characteristics. Preferably, one of the light beam segments (6null; 7null) is mesotopically tuned. In particular, a first light beam segment (6; 7) comprises a considerable amount of white or yellow-orange light, and a second light beam segment (6null; 7null) comprises a considerable amount of blue-green light.
