Embodiment Construction

[0026] figure 1 A cross-sectional view of a notching and forming machine (Oberfraese) 100 is shown. The notching and forming machine 100 rests on the working area or also on a surface 111 to be processed. The surface 111 can be, for example, the surface of a workpiece 101 to be processed. The notching and forming machine 100 rests on said surface 111 via a base plate 102 . The bottom plate 102 of the slotting and forming machine 100 is connected with the housing 103 of the slotting and forming machine 100 through some guide columns 104 . In addition, the slotting and forming machine has a cutting head 105 .

[0027] The lighting of the slotting and forming machine 100 consists of two LEDs 106a and 106b arranged obliquely. These LEDs 106 a and 106 b are located on the tool holder 107 .

[0028] The light-emitting diodes 106a and 106b are attached to the tool holder 107 in such a way that they emit light beams 108a and 108b which form an angle α with the vertical. In this ...

Abstract

In a manual tool with a light source for lightening the work area processed by the manual tool, the light source is arranged in the manual tool for irradiating at the work area by confirmed angle of incidence. The light source emits one basically parallel beam, which not only irradiates the central working point but also irradiates the ordinary surrounding work area.

Description

technical field [0001] The invention relates to a hand-operated tool. Background technique [0002] A power tool is known from DE 8529779 U1, which has a light mounted on or in the housing of the power tool. The illuminant is used for illuminating the work place to be processed with the power tool. The illuminant is arranged such that it emits a divergent light beam which obliquely illuminates the working place. Thanks to the arranged light, the user can also work with the power tool in difficult light conditions. The illuminant is designed in such a way that the entire working place and its surroundings are broadly illuminated. [0003] Furthermore, a lighting device for a circular saw is known from WO 99 / 02310. In this case, the lighting device has a plurality of light sources which each fulfill one of two different functions. A separate light source is used for broad and general illumination of the working place, whereas a separate light source is used to project a t...
