Embodiment Construction

[0026] Figure 1 shows a cross-sectional view of a slotting and forming machine (Oberfraese) 100. The grooving and forming machine 100 rests on the working area or also on a surface 111 to be processed. The surface 111 may be, for example, the surface of a workpiece 101 to be processed. The slotting and forming machine 100 is placed on the surface 111 through a bottom plate 102. The bottom plate 102 of the slotting and forming machine 100 is connected to the housing 103 of the slotting and forming machine 100 through some guide posts 104. In addition, the grooving and forming machine has a cutter head (Fraesaufsatz) 105.

[0027] The lighting of the slotting and forming machine 100 is composed of two light emitting diodes 106a and 106b arranged diagonally. These LEDs 106a and 106b are located on the tool holder 107.

[0028] These light-emitting diodes 106a and 106b are fixed to the tool holder 107 in such a way that they emit light beams 108a and 108b that form an angle α with the...

Abstract

In hand tools with a light source for illuminating the working area to be processed by the hand tool, wherein the light source is arranged on or in the hand tool in such a way that it can illuminate obliquely at a defined angle of incidence On the working area, since the light source emits a substantially parallel beam of light, it is possible to illuminate not only the central processing point, but also the general surrounding working area.

Description

Technical field [0001] The invention relates to a hand-operated tool. Background technique [0002] An electric tool is known from DE 8529779 U1, which has a luminous body mounted on or in the housing of the electric tool. The luminous body is used to illuminate the working position to be processed by the electric tool. The luminous body is configured in such a way that it emits a divergent light beam that illuminates the working position obliquely. Due to the luminous body provided, the user can also work with electric tools under bad light conditions. The luminous body is constructed in such a way that the entire working position and its surrounding environment are illuminated in a wide and open manner. [0003] Furthermore, WO 99 / 02310 discloses a lighting device for circular saws. Here, the lighting device has a plurality of light sources each fulfilling one of two different functions. A single light source is used to illuminate the work position broadly and universally. In c...
