The flash unit further includes an energy quantity control device, by means of which it is possible to provide for each light source channel any desired energy quantity from a minimum charge to a maximum charge of the at least one energy storage element, and a color temperature control device, by means of which it is possible to set a color temperature for each light source channel independently of the energy quantity provided therefor. The functions of all light source channels are fully equivalent.

Abstract: The invention relates to a folding reflector (1) having shade spokes (5) that are annularly hinged on a bearing body (7), by which spokes a reflecting cover (3) can be mounted. The reflector is characterized in that the ends of the shade spokes (5) that turned toward the linkage thereof extend beyond said linkage respectively and in that, due to the effect on said sections (9) of the shade spokes (5) extending beyond the linkage, said sections can be moved into the mounting position and back.

Abstract: The invention relates to an illumination device for flashlight photography comprising at least one reflector chamber which, in use, can be arranged in the direction of an object being photographed, having at least one reflector and at least one flash element arranged in the reflector chamber as first light source, as well as at least one UV filter element which, in use, covers the reflector chamber on a radially extending outer face in the direction of the object being photographed, the filter element having at least one ventilation opening. By means of the arrangement, an illumination device suitable for all fields of application is to be provided, a particular objective being to generate flash series of any desired length and at the same time to provide optimum UV protection on the illumination device. Uses of such an illumination device are also defined.

Abstract: Reflector device (10) for use in photography having an openable reflector screen (11) and a screen handle (12), at one end of which handle screen spokes (13) are hinge-mounted, and along which there is mounted so as to be displaceable back and forth a slider member (14), there being hinge-mounted on the slider member (14) bracing spokes (15), the opposite ends of which are joined in articulated manner to the screen spokes (13), the slider member (14) being displaceable back and forth along the screen handle (12) by means of a rope drive (19 or 26).

Abstract: A ring-shaped luminaire has a luminaire housing with an opening for a camera lens. At least one illumination element is arranged inside the luminaire housing behind a light passage of the luminaire housing. An attachment is arranged on the luminaire housing. The attachment has at least one honeycomb louver that is positioned in front of the light passage. The attachment has an opening for the camera lens.

Abstract: A photographic light comprises a main reflector with a light aperture, which is closed by a diffuser, and light sources, arranged in the photographic light casing and emitting luminous rays that reach the diffuser. A portion of the diffuser is exposed to the luminous rays of at least one second light source which reach the diffuser in addition to the luminous rays of at least one first light source. The additional second light source creates an area of increased light concentration at the diffuser. During the photographic step the photographic light is arranged such that the mat gloss objects to be photographed are positioned in the area of the increased light concentration, thereby generating strong reflections at the mat gloss surfaces, which are easily discernable from the surrounding areas.

Abstract: A lighting and flash device comprises a flash tube with a corresponding ignition device and at least two energy storage device units. The voltage of the energy storage device units is independently adjustable. When the voltage of the energy storage device units is accordingly divided, the resulting color temperature, in practice, is held relatively constant within allowable limits.

Abstract: In a method of measuring the flash duration of a flash unit, the momentary light intensity is converted into an electrical signal that is determined and stored, and that is delayed by at least that time interval that exists between the beginning of the flash curve and the maximum thereof. The stored maximum is compared with the delayed signal, with the flash duration being determined from the signal obtained thereby. As a result, at the maximum of the intensity/flash duration curve, the information concerning the rising leg of this curve is still available. The apparatus comprises a sensing element for the flash intensity, with the sensing element being followed by a time-lag element and a peak detector, the outputs of which are connected to a comparator, the output of which is connected to a time-interval measuring circuit.

Abstract: A device for measuring color temperature, having at least one measuring diffuser and at least one indicator for the color temperature, as well as operating elements for turning the device on and off, for resetting the measured values, and for initiating a measurement. To be able to easily and rapidly set or adjust the color temperature, the device has at least one adjustment control element for at least one remote control transmitter for adjusting the color temperature of a light source. A photographer can set or adjust the color temperature in a remotely controlled manner via the adjustment element and the remote control transmitter.

Abstract: A mount for photographic lighting equipment. The mount includes a mounting bracket and a support ring having a first axis that extends perpendicular to any given diameter of the ring. The support ring is carried by the mounting bracket, and the lighting equipment is connected to the support ring in such a way that not only is the lighting equipment rotatable relative to the mounting bracket about a second axis that extends essentially perpendicular to the first axis, but is also rotatable about the first axis.

Abstract: A reflector for photographic sources of light, whereby an umbrella-like frame that includes struts can be placed on a mounting for a light source. A connection element is provided on the ends of the struts. A flexible reflector sheathing is disposed on the frame and has a light-discharge opening remote from the mounting. The light-discharge opening has an edge region therearound. A closure member is provided along the edge region of the light-discharge opening, with this closure member being adapted to cooperate with the connection element to provide a detachable connection of the reflector sheathing to the frame.

Abstract: A photographic lamp possessing a main and back-reflector which are located respectively behind and in front of a light source. The main reflector limits a light exit aperture which is closed by a diffuser screen. The back-reflector comprises a transparent base which is partly provided with a reflecting layer. The reflecting layer is preferably applied in the manner of a graduated filter, so that the reflecting points are more numerous in the center of the base and less frequent at its periphery. The light produced is thereby extremely even and the illumination is very even, avoiding dark areas on the diffuser screen.

Abstract: An attachment provision is provided for exchangeable accessories for illumination bodies, which comprises an adapter plate having a receiving opening and which plate is attached to an illumination body for supporting an accessory having an axis. The adapter plate has at least two recesses for receiving and supporting an adapter flange of an accessory. The recesses are disposed at a distance, but are not disposed such that they would meet the requirements of an n-fold rotation axis with n equal to or larger than 2 for said axis. The accessory is provided with an adapter flange with at least two cam toes to grip through the recesses of the adapter plate. The cam toes are disposed at a distance, but are not disposed such that they would meet the requirements of an n-fold rotation axis directed vertically to the flange plane with n equal to or larger than 2 for said axis and where the cam toes support the accessory.

Abstract: A housing for a flash apparatus with at least one socket arranged on the housing of the apparatus for connection with flash tubes, which includes a condenser provided in the housing. On the housing there is arranged an adjustable locking device which includes at least one adjustable latching member for locking or blocking the socket for the flash tube, and also includes at least one control element which is adjustable together with the latching member. In the path of movement of the adjustable control element there is arranged a control pin of a network switch which is preferably a microswitch.
