Description

Lighting equipment with a light effect differentiated.

The present invention relates to an equipment of lighting with a differentiated light effect, in particular for Create preselected light effects.

In the field of lighting they have been manufactured numerous types of lighting equipment for walls and ceilings, which they have a containment body for one or more light sources for the emission of light to the outside.

In some cases, however, there is a need to a special emission of light that, in addition to its function as normal lighting, also improve the environment that is going to to illuminate.

In particular, a configuration has not yet been configured. lighting equipment capable of providing a light effect differentiated, which generates specific light effects, possibly also preselected at the user's request.

The equipment with light effects, available So far, it is suitable only to create effects well located, for example in the form of simple beams or bands bright, which do not provide optimal lighting.

Document DE 201 07 875 U describes a lamp to create preselected light effects, which is provided with a light source housed inside a body transparent. The transparent body has a sheet partially transparent with an outgoing configuration in so less part of its surface.

The objective of the present invention is to give know a lighting team that provides lighting optimal and effective, also creating a light effect differentiated.

Another objective of the present invention is to create specific light effects, of the preselected type, and suitable for the environment for which they are intended.

A further objective of the present invention is to announce a lighting equipment that, in addition to an effect Differentiated luminous, provide clear illumination and properly defined.

These and other objectives, according to the present invention, are achieved by lighting equipment with a differentiated light effect, in particular to create effects preselected lights, as described in the claim one.

Other features of the present invention they are the objective of the attached subordinate claims.

The characteristics and advantages of the team lighting with a differentiated light effect, according to the present invention, will become more clearly apparent from the following description, provided by way of illustration, but not limiting, referring to the attached figures, in the that:

Figure 1 is a perspective view of a lighting equipment, with a differentiated light effect, according to the invention, in a first illustration;

Figures 2 and 3 are two section views different from the equipment, as illustrated in figure 1;

Figure 4 is a section of a detail of a quarter of an external containment body, which presents in section an elliptical shape, of the equipment illustrated in the figure one;

Figures 5 and 6 are elevation views, front and side, of a second illustration that hangs from the ceiling;

Figure 7 is a perspective view of a third illustration of the lighting equipment, with the same innovative concept of the above, which hangs on a cable.

Referring in particular to the figures 1, 2 and 3, the lighting equipment, with a light effect differentiated, according to the invention, is indicated, together, with the numerical reference 11.

Said lighting equipment 11, with an effect Differentiated luminous, it is particularly advantageous to create light effects, also of the preselected type by the user, as can be seen from the following description.

The lighting equipment 11 comprises a body of external containment 12, suitable to accommodate at least one light source, such as a lamp 13, to which a double projector 30.

The projector 30 has a surface perforated 31 and a flashing or spacer 32 between its two parts. In this way, the emitted light (from the perforated surface and spacer) illuminates the internal surface of the equipment in its set, expanding the entire volume. This light source 13 is usually be supported by a relative support base or lampholder 14, with adequate support inside the containment body exterior 12.

In particular, according to the invention, the body of outer containment 12 has a rounded shape and consists of transparent material, such as polycarbonate or the like. Obviously, it can also be made of glass, or even of crystal, even if, in this case, the cost increases considerable.

Figures 1, 2 and 3 illustrate how the body of outer containment 12 has the ellipsoidal shape and consists of two parts 12a and 12b, close to each other and fixed together, using any of the procedures known in the field of illumination. Inside the two parts 12a and 12b of the body 12 there is a clamping structure, schematized in the reference 15, which helps maintain both parts and withstand the base or lampholder 14, and everything necessary for the correct operation of the equipment 11.

The invention also offers that said equipment 11 present a series of localized areas, with transparency differentiated, in its outer containment body 12, for the light emission at different intensities. In the illustrated example in figures 1, 2 and 3, said series are located in the parts or zones 16, 17 and 18. This specific arrangement of zones located, which have a differentiated transparency, you can see in the section scheme of a quarter of the ellipsoid, illustrated in figure 4, in which three of the aforementioned series of parts are arranged along sectors of the outer body 12 and are located by means of the X and Y axes. These parts 16, 17 and 18 are obtained by textures or knurled areas or polished, which allow a greater or lesser transmission of light. Further, parts 16, 17 and 18 may also allow a transmission directional light, so that it is emitted in the direction preselected

In addition, in the example of Figures 5 to 7, the outer body 12 also has an "equatorial" perimeter or central annular zone, where there is at least a part additional with a differentiated transparency 19 with respect to three previous series of parts located 16, 17 and 18. In particular, this additional part, with a transparency differentiated 19 in an annular equatorial position, provides, In addition, a reinforcement capable of supporting the lighting equipment with greater security.

The team as a whole is willing to allow a diffusion of particular and variant light, emitted by the internal light source 13.

Figure 1 illustrates how such equipment can hang from the ceiling (not shown) by means of elements of suspension 21, such as cables. These cables 21 are, by example, fixed to the perimeter zone where the two parts 12a and 12b are attached, linked to the internal holding body 15 or possibly by means of suitable coupling elements 22 fixed to the outer containment body 12.

In this embodiment, the perimeter equatorial or central annular zone 19 has been removed and therefore  the sectors are whole in both parts 12a and 12b, as illustrated in the section of figure 4.

Finally, Figure 7 illustrates a third additional example of the lighting equipment that uses the same innovative concept than the previous ones but, in this case, it is hung on the ceiling (not shown) by means of a cable 20. The outer body, in this case, only presents the additional part or equatorial perimeter or central annular zone 19 and the rest of the Body is smooth and transparent.

In figures 5 and 6, the containment body 12a consists only of one of the two parts, closed and fixed on a roof 23, forming a semi-ellipsoid. He outer body, as mentioned above, presents both series of parts located 16, 17 and 18 and, in addition, the part or equatorial perimeter or central annular zone 19.

It is evident that the outer containment body it can also be simply a sphere, hemisphere or form similar, without departing from the scope of the present invention.

There must be at least two sets of parts located, with a differentiated transparency, for an emission of light at different intensities, in order to obtain the effect minimum light according to the invention.

The emission of light forms clear rays and uniforms that are emitted from the equipment 11, according to the invention, in preferential addresses

The characteristics of the lighting equipment with a differentiated light effect, in particular to create preselected light effects, are clearly set from manifest through the above description.

This preselection is, in fact, carried out by the simple arrangement of a chosen number of series with a density defined.

There may even be parts where the outer containment body is simply transparent, with the in order to create a simple light effect, similar to that produced by known devices that can be added to those created by previous series.

From the previous description, the objective of the invention, together with its advantages, is evident.

In addition, it is clear that they can be applied numerous variants to the lighting equipment, with light effect differentiated, in particular to create light effects preselected, object of the present invention, without departing of any of the principles of novelty that characterize the idea Inventive illustrated.

In the practical embodiment of the invention, materials, shapes and dimensions of details illustrated may vary according to demands and can be replaced for other technically equivalent alternatives.
