Description

Self-luminescent signal of security.

Field of the Invention

This invention concerns a signal of the so-called self-luminescent, which is intended to be seen in the absence of ambient lighting and, therefore, not only fulfills a merely indicative function in places of low illumination (such as inside underground car parks). , dance halls or shows, industry ships-
them, ...).

Prior art

With the term "luminescence" is designated that light that is not associated with the existence of high temperatures, but the emission of radiation in the spectrum of the visible light is produced in ambient temperature conditions, even being low; that is why it is also known with the name of "cold light".

The explanation of this phenomenon is in the behavior of electrons in the atomic structure of the matter. When a solid material is under the influence of a energy source, as is that of a light radiation of any type (ambient light, solar radiation, electric lamp), said energy is absorbed by the atomic structure with the result of electrons jumping into an energy orbit higher; when the excitation produced by the source ceases energy, these electrons, by natural tendency, return to their stable orbit releasing the energy they had accumulated.

Depending on the nature of the source This type of luminescence will be called energy; as an example, radioluminescence (caused by irradiation with α, β, or γ) rays, the cathode luminescence (caused by bombardment of a cathode with accelerated electrons), chemiluminescence (caused by chemical reaction), triboluminescence (originated by energy mechanical), sonoluminescence (caused by sound waves), between others. Special mention deserves photoluminescence, which is what The present invention is concerned. This type of luminescence is the originated by an electromagnetic energy source (radiation visible and ultraviolet radiation, for our purposes), as is by example that comes from ambient lighting lamps or from sunlight. Depending on the duration of the light emission (when the excitation produced by the energy source), the luminescence of This type is subdivided into fluorescence, when light emission ceases almost instantaneously, and phosphorescence, when the emission of light endures for an appreciable time.

For the purposes of the present invention this photoluminescent property of matter is being used in signaling to make signals that, beyond facilitating their vision by the public concerned under normal circumstances of their activity, are of special relevance as security elements in case of emergency situations, to encourage evictions and escapes in the fastest, most orderly and, in short, the safest way.

In particular, the existence of signals that have the photo-luminescent property of phosphorescence type, although with quite discrete yields that they are very critical in emergency situations (evacuation of underground parking lots, large commercial areas, industrial plants, etc.); Thus, the average currently stands at a self-luminescence value of 15 mini-candles at 10 minutes after cessation of light excitation, and 3 mini-candles at 60 minutes of said cessation.

As the basis of this invention have been found two main reasons that are responsible for such low yields. On the one hand, the one that the signals are painted directly on the wall or floor or made over metal plates or other opaque supports that are fixed by direct attachment to the wall or floor. In this regard it should be noted that so far the occasional use of signals made on Crystal has a mere aesthetic functionality that is not linked with the phenomenon of self-luminescence and that is based on the glue of a self-adhesive sheet that incorporates the corresponding symbology.

Explanation of the invention and Advantages

Faced with such a state of affairs, the present invention presents a self-luminescent signal of security offered by a particular constitution in which the body support is a transparent or translucent plate made of crystal, methacrylate, polycarbonate, or other transparent material or translucent, said transparent or translucent support body has on its back applied the self-luminescent material in the form of a frame adjusted or not to the contour of it and that It frames the symbols that in each case are characteristic of the Signal in question, whose frame and symbols self-luminescent, once applied on the plate transparent or translucent, receive dorsally, along with it, a fixing layer also translucent and of the normalized color according to the type of signal (danger, informational, ...), and whose support body transparent or translucent is provided with mounting means not attached to the wall, which consist of spacer bushings that are arranged in the corners or other appropriate places of the transparent or translucent support body and that they receive internally two screws for wall anchor plugs.

In accordance with this recommended constitution the self-luminous material (often a vinyl sheet adhesive) receives the light energy that charges it both through the transparent or translucent front of the plate as through the colored and translucent paint layer applied as fixative and as a carrier of the normalized background color (green, red, ...) that he must have the signal according to his mission; that is, it is exposed to the power source both frontally and dorsally, since the signal It is mounted separately from the wall allowing the lighting also access through the gap between them; saying otherwise this separation of the signal from the wall enables the signal power supply to be greater, which which results in higher performance that translates into that at 10 minutes of ceasing light excitation (blackout of ambient light) a lighting intensity of between 80 and 100 is available mini-candles (currently the average is 15), and at 60 to 6 minutes are available for mini-candles (compared to the 3 mini-candles of the solutions currently known). In this regard, the separate assembly of the wall, by means of the separating bushes facilitates the assembly of the signal, because if you need to place the signal in a section of elbow-shaped wall, the different lengths of the separating bushing, they offer the possibility of placing the signal in cantilever said signal being visible from both sides of the wall in elbow. The length of the spacer caps will be variable, adapting it to the transparency of the support and the luminescence highlight the signal and the wall finish on the The signal is installed.

Additionally, this possibility of assembly makes make the signal more visible in normal light conditions environmental, and on the other hand offers great possibilities in the aesthetic plane in terms of easy accommodation decoration environment, where the signal can be seen clearly without this ceases to be seen the decoration of the wall, which results from great interest for architectural and decorative purposes in buildings Singular, for example.

On the other hand, the fact of the use of a glass support, methacrylate, in short a translucent or transparent material since said support protects the self-luminous paint of agents external to it such as dust and makes cleaning possible, thus preventing degradation of luminous properties of the paint extending the use of the signal in optimal conditions.

Another feature of the invention is that said transparent or translucent plate already constituted as an auto- signal luminescent is mounted as a front cover or complementary to a light source such as a conventional emergency light.

Another optional feature of the invention is that the outline of the signal has a steel frame incorporated, what which fulfills the double function, on the one hand the one to beautify, and by Another part is to protect from bumps.

Exhibition of a preferred embodiment

Regarding the drawings and references above listed, an execution mode is illustrated in the attached drawings preferred object of the invention, which concerns a signal of self-luminescent type safety that, such and As Figure 1 illustrates, it is that the support body (1a) is a transparent or translucent plate made of glass, methacrylate, polycarbonate, or other transparent material or translucent, said transparent or translucent support body (1a) it has the material applied on its back self-luminescent in the form of a tight frame (1b) or not to the contour of it and that frames the symbols (1c) that in each case is characteristic of the signal (1) in question, whose frame (1b) and self-luminescent symbols (1c), a once applied on the body transparent or translucent support (1a), receive dorsally, along with it, a fixing layer (1d) also translucent and of the normalized color according to the type of signal (1) (danger, informative, ...). Said signal (1) is provided with mounting means not attached to the wall, which consist of spacer bushes (3) that are arranged in the corners or other appropriate places of the transparent support body or translucent (1a) and internally receiving two screws (5) for anchor plugs (6) to the wall (7). The length of the spacer bushings (3) will be variable, adapting it to the transparency of the support (1a) and the luminescence highlight the signal and the wall finish (7) on which the signal (1) is installed.

Through these separating bushings (3) you facilitates the assembly of the signal (1), since if you have the need to place the signal (1) on a wall section (7) in shape elbow, the different lengths of the spacer sleeve (3), offer the possibility of placing the signal (1) in cantilever being visible said signal (1) from both sides of the wall (7) in elbow.

Figure 2 clearly shows the various components of the invention, as well as their assembly order relative, making the aforementioned property evident according to which it has a high absorption capacity of the light energy inherent in ambient lighting, so that, when it is missing, the signal (1) is able to provide a more intense luminosity and for longer, since, after 60 minutes is able to give more than double the minicandelas that give the signals hitherto known, this means that in a span of 120 minutes will still give 3 or 4 minicandelas, that is the same that give the known signals in half the time (60 minutes)

According to the invention, a application consisting of said transparent support body or translucent (1a) already constituted as a signal (1) self-luminescent is mounted as a front cover or complementary to a light source such as an emergency light conventional.

Another feature of the invention is the intended to provide protection from the contour edge of the signal (1), this option according to which the represented in figure 3, and that is that the outline of the signal (1) has a steel frame (9) incorporated.
