Description

LUMINOUS DISPLAY SYSTEM FIELD OF THE INVENTION

The present invention relates to the field of light displays, in particular light displays using constructions such as, for example, apartment buildings and / or offices, hotels, bridges and other superstructures preferably having large dimensions, for install multiple sources of light and / or light projection. The invention more particularly relates to means for the diffusion in space / time of long-range light messages.

TECHNOLOGICAL BACKGROUND

It is known to practice large displays, especially in the stadiums, by means of small projectors of medium power. These projectors may include incandescent lamps, LEDs, neon tubes, or others, while the power of the projectors is chosen according to the space between the different projectors. The longer these are spaced, the more the projectors must be powerful. But if we increase the power of the projectors in a small space, we get a blur, which prevents a good visibility of images or projected messages. In addition, the visibility / readability of the messages varies greatly depending on the angle from which one looks at these displays.

Furthermore, the patent application US 2005/0116667 A1 describes modular means, in the form of juxtaposed tiles, forming addressable light units that can make signs and other displays. In the German utility model DE 297 16 598 Ul is described a system for advertising projection on facades. The projector should be facing the front, which should be solid and solid to serve as a screen.

German patent application DE 40 39 034 A1 discloses a system for displaying numbers and letters using a facade having a large number of regularly arranged windows, including illumination by existing interior lighting and concealment by means existing closure ensures the pixels of the display. The improvement of the resolution can only take place by a complementary use of the interstitial spaces, that is to say, intervals between windows (necessarily occult or non-luminous). There is a need for large and very large displays, both permanent and eventful.

SUMMARY OF THE INVENTION An object of the invention is to provide a device and a method for producing light displays having a large range and excellent visibility / readability.

Another object of the invention is to provide a device and means for providing animated wide-angle light displays. Yet another object of the invention is to provide devices and means for displaying direct and / or indirect messages and / or in color, over large areas and with a long range.

These objectives are achieved by means of a luminous display system comprising a multitude of long-range projectors arranged in the plane of a structure or close to it, while said structure is chosen from the facades of buildings, the superstructure of bridges, the structures of imposing buildings and / or permanent or temporary modular structures.

Other objects of the invention will become apparent from the following description, wherein the described embodiments are provided for illustrative purposes only, and in no way limit the scope of the invention.

BRIEF DESCRIPTION OF THE DRAWINGS

The invention will be better understood, and other objectives, advantages and characteristics thereof will appear more clearly, in the light of the detailed description below of the preferred embodiments, given purely by way of illustration and in no way limiting, while what is appended to the said description is a drawing board in which:

FIG. 1 represents, in a diagrammatic front view, a matrix of projectors of a device according to the invention installed on a building façade schematized by a grid rectangle, in a lit position giving luminous points represented symbolically by black squares on FIG. 1. DETAILED DESCRIPTION OF THE INVENTION

The device according to the invention comprises a multitude of projectors, preferably about 450 watts each, arranged at a distance of about 3 to 6 m, preferably about 5 m, between the respective centers of two of they, the projectors being fixed in the plane of a structure or close to it, while said structure is chosen from the facades of buildings, the superstructure of bridges, the structures of imposing buildings and / or structures modular permanent or temporary.

Preferably, the projectors have an aperture angle of about 60 to 120 degrees of angle, preferably about 90 degrees of angle.

Preferably, the projectors are arranged in an orthonormal grid, so as to constitute substantially an orthonormal matrix of beams or light spots, depending on the distance to which one is placed.

In one embodiment, the device according to the invention implements fixed projectors and giving permanent lighting.

In alternative embodiments, the projectors of the device according to the invention are alternately switched on or off, are blinked, and / or are arranged to emit a light of different colors, all or only one or more parts. of the set of projectors present in the device.

Advantageously, the alternations of ignition and / or extinguishing, blinking and / or color choice, among others, are programmed and triggered by a computer system equipped accordingly. However, forced and / or alternative manual operation is also possible.

By means of a device according to the invention, one can realize displays of words and / or images of up to about 6500 m ² , while it is also possible to combine several buildings and / or structures of other nature. for arranging modules, independent or dependent, of sets of projectors having an amplified range and / or a larger developed surface.

In practice, the projectors implemented in this device operate as the pixels of television screens and other displays operating by points. For example, to make the letter "I" appear, it is recommended to align 4 to 5 projectors practically equal distances which vary according to the respective powers of the projectors used and the resolution that one wishes to obtain.

In a preferred embodiment, the projectors are installed on, behind or in front of openings of a building such as windows of such a building which are visible from afar.

By way of nonlimiting example, it is possible to obtain with about 100 projectors about 450 watts distant about 5 m and placed on a building about 40 m high and about 160 m long, a message projected so as to be visible over a distance of about 50 km.

Alternatively, a color image can be provided by matching several

in practice two or three or more projectors of different colors (for example of red color, blue color and green color), and arranging them side by side as on the screens of televisions.

In a particularly preferred embodiment of the invention, all or part of the projectors thus installed consists of projectors known to those skilled in the art as halo projectors. Such projectors, usually of a power of about 450 watts and having dimensions of about 20 × 30 cm provide a beam whose vision is similar to that of a luminous ball providing a halo effect when said beam is seen at a great distance, in practice about 500 m and beyond.

In another embodiment, the variable light sources can further be made into power, and thus allow the projection of images or messages having intensified, attenuated and / or evanescent portions. The resulting images can then be considered animated.

In another aspect, the device according to the invention can be arranged to project the light messages indirectly, for example by projecting the light emitted by one or more of the projectors onto a reflecting surface or onto an image which is then itself the visible surface at a distance.

In another embodiment provision is made to provide, in front of all or part of the aforementioned projectors, a panel or translucent panel fragment, comprising a message or part of a message to be projected. The distance between the projector and said panel is adjusted by those skilled in the art such that the projection of the message or part of the message is appropriate for reading in a range of distances in which the message or the message part as well The projection is appropriately enlarged, with no detrimental overlap, while the magnification for message parts is such as to make the message portions thus enlarged substantially jogged or at least spaced by a relatively small interval for the eye. In order to be operational, the device according to the invention comprises means of supplying energy, in particular electrical energy, autonomously or by connection to the local electrical network, as well as connection and interconnection elements, between the various projectors and / or between these and at least one computer system, arranged to be able to act on the projectors, possibly in cooperation with traditional switches, dimmers and / or modulators. The device may also include, optionally on some or all of the projectors, one or more color filters, fixed or movable, and in the latter case with assistance by a numerical control. In yet another aspect, the invention relates to a luminous display method, which comprises the implementation of at least one device as described above. Advantageously, the method comprises the implementation of a multitude of projectors, preferably about 450 watts each, arranged in such a way that their respective centers are distant from about 3 to 6 m, preferably about 5 m , the projectors being fixed in the plane of a structure or close to it, while said structure is chosen from the facades of buildings, superstructures of bridges, imposing building structures and / or modular structures permanent or temporary. Preferably, projectors with an opening angle of about 60 to 120 degrees of angle, preferably about 90 degrees of angle, are installed in such a configuration.
