<P>PROBLEM TO BE SOLVED: To solve the problem of mutual interference between distinct optical systems designed for a lamp constructed according to the principle of the solution of a module. <P>SOLUTION: The module for projecting a light beam comprises: a light source 10 suitable for generating the light beam; a substantially flat support surface 20 on which the source is arranged in a manner to emit the light beam from only one side of the surface; and a curved reflecting surface 30 which extends on one side of the support surface and has its cavity facing the support surface, and which is capable of reflecting the light beam originating from the source in a principal direction substantially parallel to the support surface of the source, the reflecting surface being divided into a plurality of reflecting areas (31, 32 and 33) suitable for receiving respective portions of the light beam. The plurality of reflecting areas comprise at least one area (32 or 33) such that the portion of the light beam reflected by that area is substantially collimated in a vertical direction and has a small horizontal divergence α less than a first predetermined angular value α<SB>1</SB>, and at least one area 31 which is designed in a manner such that the portion of the light beam reflected by that area has a wide horizontal divergence α greater than a second predetermined angular value α<SB>2</SB>. <P>COPYRIGHT: (C)2008,JPO&INPIT |
