    摘要： The present invention is based on a regulation circuit (200a, 200b) for making available a constant current supply on the basis of a transformer principle, in which there flows through the luminescent diodes (D1, . . . , DN) a triangular a.c. current (ID) varying periodically around a d.c. current value. With this method it is afforded by means of a circuitry provision that both the charging and also the discharging current (IL1) of an inductive reactance (XL1) connected in series to the luminescent diodes (D1, . . . , DN), functioning as a storage choke (L1) for filtering of mains harmonics, flows as diode current (ID) through the luminescent diodes (D1, . . . , DN). The advantage of this method consists in a significant reduction of the overall power loss (PV, ges) of the LED illumination module (100). According to one exemplary embodiment of the invention the ceramic circuit board (102) of the LED illumination module (100) in accordance with the invention has a direct mains current supply (104, 108), which for protection from mechanical damage is accommodated in a transparent housing (106) having a highly transparent polymer mass (110) serving as optically active lens surface.

    摘要： The method for determining segment times (Tk) required for controlling an internal combustion engine includes providing a transducer disk (17) connected to a camshaft of the engine with a plurality of markings equally spaced from each other on the transducer disk; measuring respective segment times (Tk) between detection of corresponding pairs of markings on the transducer disk (17) by means of a camshaft sensor (21); triggering fuel injection events and combustion events in order to trip acceleration events at a substantially constant camshaft rotation speed; determining a resulting acceleration quotient (Qk) for a current segment time as a quotient of the current segment time divided by a preceding segment time and correcting a following segment time by means of the acceleration quotient (Qk) for the current segment time. The method is not performed when the internal combustion engine has a crankshaft with a properly working crankshaft sensor for measuring crankshaft rotation speed.
