Abstract: A hand-held power tool includes a housing, in which at least one drive unit configured to drive a tool holder is arranged. The tool holder is designed to hold an insertable tool. The hand-held power tool includes an alignment apparatus having a control unit and at least one luminous element arranged on the housing. The alignment apparatus is designed to determine, in real time, during operation of the hand-held power tool, a current deviation of a selectable machining angle, which is selected via the control unit and which is formed between the insertable tool inserted in the tool holder and a workpiece surface that is to be machined, from an actual inclination angle between the insertable tool inserted in the tool holder and the workpiece surface to be machined, and to visualize said deviation using the at least one luminous element.

Abstract: A circuit for the generation of ignition pulses for a lamp has: an ignition pulse transformer, a device for the generation of ignition pulses (ignition pulse generator) at a primary winding of the ignition pulse transformer, which are transformed in the secondary winding of the ignition pulse transformer, a voltage detector for the detection of the voltage value of the transformed ignition pulses, and a voltage regulator for regulating the voltage value of the transformed ignition pulses to a predetermined reference value. The ignition pulse generator has, in a series circuit, a pulse capacitor and a switch, parallel to the secondary winding of the ignition pulse transformer and the lamp, wherein the regulator for the voltage value of the transformed ignition pulses sets at the pulse capacitor the voltage applied at an ignition time point. The voltage at the pulse capacitor can be set by means of selection of the switch-on and/or switch-off time points of the switch.
