DESCRIPTION

Lamp

Technical field of the invention

The present invention describes a new type of versatile and easily modifiable lamp to offer different types of lighting by replacing or exchanging filters and reflective materials.

Background of the invention

A large number of lamp models are known, each with different functionalities. Some of them, such as those described in ES2237349A1 and EP513907A2 offer easily replaceable filters to generate different optical effects.

In this and other cases, the replacement of the filters completely affects each light source. It is not possible to place filters or sheets with different optical properties in part of the area illuminated by each source, except by creating a filter that is divided asl. However, that solution is expensive, complicated and not very versatile.

Object of the invention

The problem solved by the different embodiments of the present invention is to find a lamp that is easily configurable, reliable and that allows to selectively vary the lighting effects (intensity, color, diffusion ...) even allowing to define different effects in different parts of the outer screen thanks to the combination of different sheets and / or relative positions between them.

From the sheets that form the lampshade lamps, and that can correspond to filters, reflective surfaces, die cut, color, etc. It changes the perception of the generated light and the perspective of the luminaire itself. The construction of the most preferred embodiment is easy to assemble and allows the user to choose, apart from the light element (color temperature, power ...), the filters and light effects and the combination in each orientation.

In the most preferred form, the combination of two cubes forming a tesreact allows a simple change of the sheets, and a great simplicity in their construction, by allowing to use more pieces with the same shape.

The lamp of the invention comprises a support base of a luminous element (halogen bulbs, LEDs or other light source). Around the luminous element, and generally supported on the base, it has two nested screens, generally coaxial, formed by two polyhedra, and where at least one of the faces of at least one polyhedron (preferably all the faces of the two polyhedra) is removable . The faces will be formed by sheets that can be removed from their edges and that have optical characteristics of interest.

Generally, one face of each polyhedron will be absent, for the passage of the luminous element into the screens. It can also be introduced through an edge or a vertex. Likewise, it can comprise a fixed face where the polyhedron corresponding to the luminous element or the base is fixed. "Visible" faces refer to those visible from the outside, generally all but the passage face of the light element.

In a preferred embodiment, the polyhedra are supported by an articulation that allows their relative rotation (one polyhedron with respect to the other), that allows their joint rotation on the base or that allows both types of rotation. If it is desired that they can rotate 360 °, the inner polyhedron will have to be smaller than the sphere circumscribed to the outer polyhedron. In this way, sectors of different sizes can be generated where the light passes through different faces and therefore their characteristics vary.

A second solution is that the screens are simply supported on the base, and can be repositioned in any desired position.

In another embodiment, the polyhedra are centered on the luminous element, that is to say its vertical axis coincides with the luminous element.

The faces of the polyhedra can be screwed, magnetized, clipped, etc. However, it is preferred that they are mounted on glues arranged on the edges of the corresponding polyhedron. If the gluttony is of sufficient width, the faces may be formed by two or more parallel sheets of smaller thickness.

To increase the light effects, a flat space can be included in the base, with a transparent roof, below the light element and an optical layer arranged in the flat space. That optical layer will be equally substitutable.

It is advisable to define a deposit of the different usable sheets as faces of the polyhedra, the base being the natural position of said deposit.

The material of the sheets that make up the faces of the polyhedra and the optical layer will depend mainly on the desired optical aspects and the heat generated by the light element. The materials of the rest of the parts of the lamp will be wood, methacrylate, glass and any other with the appropriate appearance and mechanical resistance.

Other variants will be described in other parts of memory.

Brief description of the figures

Next, in order to facilitate a better understanding of this descriptive report and being an integral part thereof, some figures of an illustrative and non-limiting nature that represent examples of the invention are combined.

Figure 1: shows a perspective view of an example of realization of the lamp, with a flat base where an optical layer is placed. Several sheets can be seen half removed or placed.

Figure 2: shows a side view of a second embodiment with a base formed by legs.

Figure 3: shows a detail of an edge of an embodiment of the outer screen, where the ends of glues are appreciated.

Figure 1 shows a general view of a realization of the lamp, formed by a base (1) where a light element (2) is fixed, generally as one or more LED, halogen or similar bulbs.

The base (1) of the figure serves as support for two screens formed by two polyhedra

(3.4), in this case concentric, whose axis is aligned on the luminous element (2). The polyhedra (3,4) are of different sizes and fit into each other, and may be the same or different polyhedra. The different orientation means that the light passing through one face (5.6) of the inner polyhedron (3) can pass through faces (5.6) different from the outer polyhedron (4).

In the embodiment, the inner polyhedron (3) is of dimensions smaller than the sphere circumscribed to the outer polyhedron (4) so that they can rotate with each other without being affected. This rotation can be of various forms, for example by connecting the polyhedra (3,4) to the base (1) by means of one or more joints that allow the relative rotation between the two polyhedra (3,4), and preferably both with respect to the base (1). The articulation can be physical (a bearing or similar) or correspond to projection guide channels at the bases of the polyhedra (3,4), or any other system that allows relative rotation without changing the position of the center of the rotating component . Similarly, the polyhedra (3,4) can be simply supported on the base (1), allowing their placement in any relative position.

The polyhedra (3,4) will preferably be regular so that they are formed by a series of equal faces (5,6). The preferred solution is a cube, although a dodecahedron is also preferred.

The faces (5,6) of the polyhedra (3,4) will be sheets with certain optical characteristics: color, opacity, reflectance, diffusion, grinding, filtering ... including sheets with holes, punches, meshes or drawings. The faces (5,6) of at least one polyhedron

(3.4) will be removable to be replaced by other sheets of different characteristics and so! vary lighting effects. If the rotation around the joint is also used, the variability of effects is highly increased.

In a preferred solution, the removable faces (5,6) are fixed to the edges of the corresponding polyhedron (3,4) by means of glues (8) in said edges (Figure 2). The shape and disposition of the glues (8) will depend on the orientation of the face (5,6)

applied and of its form. In the case of cubic or prismatic polyhedra (3,4), the glues (8) are in the vertical edges of the sides and in two parallel edges of the upper face (5,6) (Figure 3). In the inner polyhedron (3), the upper inner face (5) can be simply supported, as it is not accessible. A few highlights (not shown) 5 will prevent unwanted displacement.

The base (1) can comprise a flat space (9) (figure 1) below the light element (2) to place a layer (10) with also variable optical properties. Thus, the optical layer (10) can be reflective, colored, dark ... producing different effects. The material arranged between the luminous element (2) and the optical layer (10) will be transparent to allow direct visibility and that the properties of the layer (10) are used.

It is preferred that the base (1) has a tank (11) for the different sheets that the faces (5,6) of the polyhedra (3,4) can form. This deposit (11) can correspond to the flat space (9), placing the layer (10) above the sheets and other materials of the faces (5,6).

The lamp will have a power supply, generally by means of a connection to the network, an ignition button, optionally a way to regulate the power of the light element (2). and any other usual addition in lamps.
