Lightbox

1. A light box with

at least three base profiles which in the assembled state form a closed base frame onto which a first tensible plane material to be illuminated can be fitted such that it forms the a front side

at least one illuminant which is disposed within the base frame in order to illuminate the light box,

at least one power supply,

at least one supporting wall disposed on the base frame which has at least one attachment means for releasably fixing the illuminant and/or the power supply within the base frame, characterized in that the supporting wall is formed by a second, tensible plane material which can be attached to the base frame such that it forms a rear side of the light box,

wherein the first and second tensible materials are woven or knitted textile.

2. The light box according to claim 1 , characterised in that the first and/or second tensible plane material can be fitted in the base profile by clamping means.

3. A supporting wall arrangement for a light box according to claim 2 , wherein the clamping means comprise reinforcement strips formed on a peripheral region of the tensible plane material.

4. The light box according to claim 1 , characterised in that the illuminant is releasable connected to an attachment rail via at least one of the following: a snap-lock connection: an engagement connection; a clamp connection; or a connection by means of a hook and loop fastener.

5. The light box according to claim 1 , characterised in that at least one recess is provided for mounting the attachment means to the second tensible plane material in which the at least one attachment means can be fitted.

6. The light box according to claim 5 , characterised in that a pin is formed on the attachment means which, in order to attach the attachment means can be passed through the recess formed on the tensible plane material and can be fixed in position by counter means outside of a space to be illuminated within the light box.

7. The light box according to claim 1 , characterised in that the illuminants can be connected to one another in series by means of a ready-assembled connector system.

8. The light box according to claim 1 , characterised in that the tensible plane material is made up of several parts in the form of flexible cross members, the length of which in particular is changeable, which can be fitted into the base frame.

9. The light box according to claim 1 , characterised in that at least one reinforcement member can be fitted into the base frame in order to reinforce the base frame and/or the second tensible material in the region of the attachment means.

10. The light box according to claim 1 , characterised in that the geometric dimensions of the base frame can be adapted to the dimensions of the first and second tensible plane material by changing at least two profiles with profiles having different dimensions.

11. The light box according to claim 1 , characterised in that the supporting wall formed by the second tensible plane material reflects the light irradiated by the illuminant or transforms it into a colour effect on the rear side of the light box.

12. A supporting wall arrangement for a light box according to claim 1 , characterised in that the supporting wall is formed by a plane material tensionable by clamping means, on which at least one attachment means is disposed for the releaseable fixing of at least one illuminant and/or at least one electrical series connection unit.

13. A supporting wall arrangement for a light box according to claim 1 , wherein the power supply comprises an electrical series connection unit in order to supply the illuminant with current.

14. The light box according to claim 13 , characterised in that the at least one electrical series connection unit required for the power supply is pre-fitted on the second tensible plane material.

15. A supporting wall arrangement for a light box according to claim 1 , wherein the illuminants comprise at least two illuminants respectively operable by one electrical series connection unit.
