    Abstract: The invention relates to an optical scanning head for reading an optical data memory. Said head comprises a substrate (12) with a principal surface, an edge-emitting laser component (30), which is located on the principal surface of the substrate (12) and whose emission axis (34) runs essentially parallel to the first principal plane, a deflection device (36), which is positioned on the principal surface of the substrate, for deflecting the laser radiation (32) in a direction that is essentially perpendicular to the principal surface, at least one signal detector (20, 22; 62) for recording the laser radiation that is reflected by the optical data memory and an optical element (40), which conducts the deflected laser radiation to the optical data memory and the reflected laser radiation to the signal detector(s) (20, 22), said optical element (40) being connected to the substrate (12) by at least one support element (36, 38). The invention also relates to a method for producing a scanning head of this type.

    Abstract: The invention concerns an LED device (1) comprising at least one LED chip (2), wherein front contact plating (8) is disposed on a light outlet surface of a light-emitting body (5) and rear contact plating (6) is disposed on a side of the light-emitting body (5) lying opposite the light outlet surface. The LED chip (2) is disposed between a first (15) and a second strip conductor carrier (31), the first strip conductor (15) being transparent and comprising at least one first electrical conductor (16) which contacts the front contact plating (8), and the second strip conductor carrier (31) comprising at least one second electrical conductor (13) which contacts the rear contact plating (6). The LED device (1) according to the invention has inter alia the particular advantage that the size of the LED chip (2) is reduced with respect to conventional LED devices and hence the beam density can be increased.
