Description

The present invention relates to a light former as an attachment for system flash devices for controlling the light characteristic with the features of the preamble of the independent main claim.

Prior art light shapers are already known in multiple forms for detachable mounting to a fastening device of a lighting device. Furthermore come Lichtformer, such as from the DE 43 00 056 C2 known, especially in the context of professional photography, but also in film and television recordings for use. They serve, in conjunction with a lighting device, or with a Aufsteckblitz (Speedlight) on which they are placed or associated with them to illuminate a certain area accordingly or to form the light so that a certain area is illuminated or is also being used.

In this context, light shapers are known in the form of so-called soft boxes, also called light tubs, which are usually mounted on a reflector. In an elongated or cylindrical extent such soft boxes are also called "Striplights". With such a light former to achieve a uniform illumination of subjects and reduces the formation of shadows. The use of several light shapers achieves a very good illumination and can almost completely avoid shadowing. A striplight is usually mounted on a tripod, on which it is very flexible in all directions adjustable by means of special brackets.

There are striplights that include real flash tubes that fire the entire length but require their own power connection and are thus relatively bulky and expensive.

Striplights are more practical, flexible and cheaper, the cylindrical body of which can be fired by means of a system flash unit and emits the light onto the motif to be illuminated via a reflective coating through a diffuser, thus being an aid for system flash units in photo technology for controlling the light characteristic. Such light shapers are available for system flash units from different manufacturers, usually with a special connection for the respective system flash unit, which usually has to be purchased. However, the device-specific connection for the respective system flash unit restricts the flexibility of the light former.

The object of the present invention is therefore to improve a light former which is suitable as an attachment for system flash units to the effect that any commercially available system flash unit can be adapted and fixed to the light former without having to use device-specific adapter for connecting system flash unit with light former.

This object is achieved in a light former with a cylindrical body (striplight) as an attachment for system flash units (Speedlight) for controlling the light characteristic and a connection for connection of system flash unit with light former that the terminal is arranged on a front end cap of the cylindrical body and mounting bracket for receiving a flash head of the system flash unit and a einfädelbares in the mounting bracket Velcro for grasping and fixing the flash head has.

Such attachment of a light former with integrated universal connection to a system flash unit or compact flash unit was so far not yet possible.

The new light former expands the possibilities of arbitrarily used plug-on flashes to save space and effectively.

Further advantages, features and details of the invention will become apparent from the embodiment described below and from the drawing.

2 : communicating tubular cover parts for the cylindrical light former according to 1 for mounting a double light former,

3 : a universal connection at the light former according to 1 for fastening a system flash unit, and

4 : Details of universal connection to 3 ,

According to the 1 is on a light former with a cylindrical body (striplight) 1 as attachment for system flash units (Speedlight) 2 for controlling the light characteristic, a connection for connecting the system flash unit 2 with the cylindrical body 1 provided on a front end cap 4 of the cylindrical body 1 is arranged and mounting bracket 5 for receiving a flash head 3 of the system flash unit 2 while the opposite end of the striplights 1 by means of a neutral Röhrenabdeckteils 18 is closable.

The cylindrical body 1 is preferably made in one piece from a plastic tube, which is half mirrored inside and allows for the other half continuous homogeneous light output. In this way a sufficient stability of the Striplights is guaranteed.

1 shows a schematic representation of a fully assembled unit of striplight 1 and flash unit 2 , The resulting unit can also be attached to standard photo tripods or light stands.

This is on the outside of the cylindrical body 1 on the half, which is mirrored inside, a holding rail mounted in the axial direction 9 is intended for tripod mounting. The positioning of the retaining rail 9 is chosen so that by means of this retaining rail 9 a balance point for the entire light shaper 1 . 4 . 5 . 18 including connected system flash unit 2 is definable.

For this one can the holding rail 9 between forefinger and thumb of a hand grab and the unit from striplight 1 and flash unit 2 balance by moving the gripping position until the horizontal is reached. Accordingly, now a clamping shoe of the tripod adapter can be mounted and about the light former mounted on the tripod and so optimally adjusted to the shooting situation, without the retaining rail 9 on the striplight 1 unnecessarily burden.

According to the 2 are by means of adapted Röhrenabdeckteile 10 . 11 , so called a stacking end cap female 10 with a central recess 12 and a so-called stacking endcap male 11 with a centric elevation 13 each at the end cap 4 for the connection 4 . 5 opposite face of the Striplights 1 according to the plug socket principle, two light formers can be plugged together to form a double light former.

3 and 4 now illuminate details of the embodiment for a connection of the light former according to the invention to a compact flash unit 2 , Two mounting brackets 5 are so on the end cap 4 of the striplights 1 mounted on the one hand by solving their fixation 15 . 16 free with respect to their mutual spacing on the end cap 4 let move (see arrow A) to the respect to the cylindrical body 1 centered shot of the flash head 3 be customizable and on the other hand afterwards fixed again. Furthermore, one is in the mounting bracket 5 threadable Velcro tape 8th for grasping and fixing the flash head 3 intended. These are the two mounting brackets 5 each of two perpendicular angle plates 6 . 7 formed, with an angle plate 6 in the radial direction by means of inserted slots 15 and screws 16 on the end cap 4 adapted fixable is (see 4a and 4b ) and the other angle plate 7 slits introduced in the axial direction 17 has (see 4c ), through this the Velcro tape 8th is so einfädelbar that between the two mutually parallel angle plates 7 in the axial direction inserted flash head 3 (see arrow B) in a straight axis with the cylindrical body 1 can be fixed. 4a also shows an exemplary embodiment of an end cap 4 as a centering aid for the connected flash head 3 acts and for inwardly directed support noses 14 having.

The control panel of the ready mounted flash 2 has advantageous in the same direction as the back, so mirrored side of the light former 1 , Of course, however, the operation of the Speedlight in all positions is always possible because the control panel remains free to move.

This is the Aufsteckblitz 2 rotated accordingly from the open side of the Velcro tape 8th between the angle plates 7 to slide (see arrow B), leaving only the flash head 3 with flash reflector centered above the inlet opening of the light former 1 . 4 is, ie, the Aufsteckblitz 2 in a straight axis with the light former 1 . 4 is positioned.

The flash head 3 it sits clamped in the holder of the end cap 4 with the support noses 14 , Velcro tape 8th and mounting bracket 5 , where the Velcro tape 8th the direct contact of the angle plates 7 with the flash head 3 prevents and damage the flash head 3 can exclude.

The Velcro is when using a sufficiently long Velcro tape 8th a predominantly textile, almost as often as possible to be solved closure means. One side of the Velcro strip with flexible barbs, the other side with loops, pressed together results in a strong but reversible quick release.

The holding function of the Velcro fastener can be additionally supported by additional Velcro surfaces on the flash head to be fixed 3 to be glued.

Due to the comparatively very compact design of the invention equipped light former can be used extremely variable. Its design-related advantages plays the light former according to the invention in particular, if the place is cramped and usually a light former of the previously known type, the work rather handicapped, ie in confined spaces, in motor vehicles, under, behind and on furniture, and in narrow niches.

The above-described light former according to the invention is therefore particularly suitable for photographers or so-called strobists who work in a confined space with a narrow band of light and still want to achieve professional results.
