The invention relates to a lighting device (10) for a motor vehicle, comprising a gas discharge lamp (12), an ignition device (14) and a separate control device (16) which can be detachably connected to the ignition device (14), said control device (16) being configured to supply an input voltage for the ignition device (14) and an operation voltage for the gas discharge lamp (12), and said ignition device (14) being configured to produce, from the input voltage, an ignition voltage for the gas discharge lamp (12). The lighting device (10) is characterised in that the gas discharge lamp (12) is configured to consume less than 30 watts of electrical power when in regular operation, and in that the ignition device (14) and the control device (16) are configured to be connected to one another in a mechanically rigid manner yet so as to be both mechanically and electrically detachable.

ATTACHMENT OPTICAL UNIT COMPOSED OF TRANSPARENT MATERIAL FOR CONCENTRATING LIGHT, LENS ARRAY COMPRISING AT LEAST ONE SUCH ATTACHMENT OPTICAL UNIT AND LIGHT MODULE COMPRISING SUCH A LENS ARRAY
The invention relates to an attachment optical unit (28) for concentrating light from a light source (22) assigned to the attachment optical unit (28) by refraction during passage through a light entrance surface (36) and/or a light exit surface (38) of the attachment optical unit (28) and/or by total reflection at an interface (34) of the attachment optical unit (28). A main exit direction (42) of the concentrated light from the attachment optical unit (28) is remitted to a main emission direction (32) of the light source (22) in a specific manner. In order to be able to direct light emitted by the light source (22) in a desired main exit direction independently of the main emission direction of the light emitted by the light source (22), it is proposed that at least one of the interfaces (34) of the attachment optical unit (28) be embodied in such a way that the main exit direction (42) of the light beam runs at an angle with respect to the main emission direction (32) of the at least one light source (22).

METHOD AND CONTROL CIRCUIT FOR STARTING A GAS-DISCHARGE LAMP
The invention relates to a method for operating a gas-discharge lamp (16) during the transition from the switched-off state without an electric arc into a state that generates light in a stable manner. According to the method, a booster capacitor (C2) is discharged via a current path, which conducts the current flowing through the gas-discharge lamp (16) and in which an inductor (L1) lies in series with at least one switch (S5), in a transfer phase that follows an ignition voltage pulse. The method is characterized in that the booster capacitor (C2) is discharged by a repeatedly alternating closing and opening of the switch (S5) in a clocked manner. An independent claim relates to a control circuit for carrying out the method.

H05B 41/38 - Commande de l'intensité de la lumière
The invention relates to a printed circuit board having an insulating support layer and a layer of conductive material applied thereto. In order to increase the flexibility of the printed circuit board, it is proposed that material from the support layer have been removed at at least one point on the printed circuit board on a side of the support layer which is opposite the layer of conductive material in order to form a straight groove which extends from one side of the printed circuit board to another side of the printed circuit board, so that the printed circuit board can be bent along the groove, wherein the material of the support layer which has remained in the region of the groove and/or the layer of conductive material in the region of the groove form(s) a bending edge.
A lighting device (1) for a vehicle, and in particular a motor vehicle headlamp, comprising a light source (3) for emitting light and a reflector (2) for focusing the light emitted by the light source (3), there being formed, at the rear end of the reflector (2), an opening to receive at least a part (18) of the light source, and a reflector neck (21) that surrounds the opening and to which the light source (3) is fastened in a defined position relative to a reflective surface of the reflector (2). The lighting device is characterized in that a plurality of locking members (23, 24, 24') are formed on the reflector (2), which locking members (23, 24, 24'), in the course of a rotary movement of the light source (3) about the optical axis (10) of the reflector (2) or about an axis parallel thereto when the light source (3) has been at least partly inserted in the reflector neck (21) in the direction of the optical axis (10), engage in corresponding perforations (17) formed in the light source (3), at least one of the locking members (23, 24, 24') co-operating with at least one of the perforations (17) in the course of the rotary movement in such a way, and causing forced guidance of the light source (3) in such a way, that the light source (3) is held in a defined position relative to the reflector (2) in the axial direction.
