Abstract

A support for light diffusers, characterised by comprising at least one glass plate (1, 1') on which at least two conducting tracks (2) are applied by a silk-screen frame.

Description

Support for light diffusers
This invention relates to a support for light diffusers.
Lighting appliances are known comprising a support consisting of a rigid frame for suspending from the ceiling, for fixing to a wall, or for resting on a base on the floor, and provided at one end with a light diffuser.
The electrical connection between the diffuser and the electricity mains is made by an electric cable which in some cases is passed through the inside of the support (with a considerable time required for its insertion) and in other cases is arranged external to the support (to the detriment of the appearance of the appliance).
These drawbacks are overcome by a light diffuser support according to the invention, characterized by comprising at least one glass plate on which at least two conducting tracks are applied by a silk-screen frame.
The present invention is furhter clarified hereinafter with reference to the accompanying drawings, in which:
Figure 1 is an interrupted perspective view of a support according to the invention; and
Figure 2 shows it applied to a lighting appliance.
As can be seen from the figures, the support according to the invention comprises substantially two plates of translucent glass 1,1', on the inside of which there are provided two tracks of conducting paste, for example based on silver. The ends of the two conducting tracks are connected to the electrical contacts of the light diffuser 3 and to the electrical mains contacts respectively.
The support according to the invention is prepared in the following manner:
two rectangular preferably translucent glass plates are taken and their edges ground. Two tracks of conducting paste, preferably silver based, are then applied along one of the two glass plates by means of a silk-screen frame, after which the plate is dried to solidify the paste.
The plates are then tempered to improve their mechanical characteristics and to bake the paste of the conducting tracks, which thus become fixed to the supports.
After this tempering stage a layer of PVB (polyvinyl butyral) is applied between the two plates, which are then placed together under vacuum so that they become irreversibly joined. The plates prepared in this manner are connected to the diffuser conductors and to the mains leads.
Instead of being glued together with PVB, the plates can be glued with a conventional glue or joined by bolts.
From the aforegoing it is clear that the support according to the invention has numerous advantages, including:
- a pleasing appearance because of the elimination of any exposed conductor,
- the fact of acting as a light diffuser, conductor and insulator at the same time, ie functions which were previously performed by separate parts.

Claims

C L A I M S
1. A support for light diffusers, characterised by comprising at least one glass plate (1,1') on which at least two conducting tracks (2) are applied by a silk-screen frame.
2. A support as claimed in claim 1, characterised in that said conducting tracks (2) are covered by a layer of insulating material.
3. A support as claimed in claim 2, characterised in that metal plate is applied to the layer of insulating material.
4. A support as claimed in claim 2, characterised in that said layer of insulating material is of polyvinyl butyral.
5. A support as claimed in claim 1, characterised by consisting of two plates joined together.
6. A support as claimed in claim 1, characterised by being formed of diaphanous material.
7. A support as claimed in claim 1, characterised by being formed of transluncent material.
8. A support as claimed in claim 1, characterised in that the layer of polyvinyl butyral is used as adhesive.
