摘要： This invention relates to a method of designing an illumination device, wherein a light source unit is modeled with a set of rays. Therein, each ray is assigned a light power and is further characterized by a light volume, which specifies how "spread out" the light is in area and angle. In this way, a selection of rays with respect to their "density" becomes possible, and an optical system can be optimized for a transmission of those rays providing the most light per volume.

摘要： A switching buck converter comprises an output stage with a first lateral branch, comprising an output capacitor (Cout) for charging at an output voltage, an intermediate branch with an inductor (L1) to circulate current in the output capacitor (Cout) and a second lateral branch with a freewheeling diode (D1) to permit current flow from ground towards the inductor (L1). A first electronic switch (Q1) is interposed between the input (In) and the output stage (D1, L1, Cout). A second electronic switch (Q2) is interposed between the output capacitor (Cout) and the control electrode (base) of the first electronic switch (Q1). A current generator (R1) injects a current (I s ) into the control electrode (base) of the second electronic switch (Q2), rendering the second electronic switch conductive and producing an alternate switching of the converter between a first operating condition, wherein the first electronic switch (Q1), having become conductive due to said second electronic switch (Q2) becoming conductive, produces a current flow in said inductor (L1) and the accumulation of charge on said output capacitor (C1), and a second operating condition, wherein the first electronic switch (Q1) opens to produce current flow through said freewheeling diode (D1), the inductor (L1) and the output capacitor (Cout), while said second electronic switch (Q2) is open.

摘要： The present invention relates to an electronic ballast for operating a hybrid luminaire having at least one discharge lamp (FL) and at least one LED. A pin of a conventional control apparatus (10) is used with a double function in order to switch back and forth between discharge lamp operation and LED operation: while the filaments of the at least one discharge lamp (FL) are being preheated, the signal which is applied to this pin serves to measure the preheating current, whereas after preheating, a control signal is evaluated at this pin in order to switch back and forth between discharge lamp operation and LED operation.
