Description

LIGHTING FIXTURE
The invention relates to a lighting fixture, comprising a hollow space which is provided with two or more groups of light sources for lighting one or more objects through an opening in the lighting fixture, in which each group comprises at least one light source, and in which the light sources are arranged statically in said hollow space.
At present, the light sources which are used in lighting fixtures of this type are preferably light-emitting diodes (LEDs).
With regard to lighting fixtures of this type, for example, US 2002136010 discloses a system having a diode light as light source for lighting a stage, or for providing theatrical and architectural lighting. The system is in this case composed of a number of separate flat panels on which a number of light-emitting diodes are fitted which emit a number of diode light beams to a common focusing region.
The problem with such a system is, on the one hand, that it requires mechanical components in order to achieve different lighting angles for lighting an area. On the other hand, a system of this type only offers a limited degree of freedom of lighting.
The problem of the mechanical components is partially solved in DE 101 29 972, in which a device is described which is provided with a number of light-emitting diodes as light source, these light-emitting diodes being arranged next to one another, for example in the form of a tube or a pipe, in order to illuminate an object which is located opposite the surface formed by the light-emitting diodes. The surface is concavely curved over at least part of the periphery. Viewed in cross section in one dimension, the curvature may have the shape of a semicircle and may extend at right angles to the plane of the curvature in a tunnel shape.
However, the problem of the degree of freedom of lighting being limited is also still present in a device of this type. It is an object of the invention to provide a lighting fixture according to the preamble of the first claim, in which the degree of freedom of lighting is as great as possible.
This object of the invention is achieved by providing a lighting fixture, comprising a hollow space which is provided with two or more groups of light sources for lighting one or more objects through an opening in the lighting fixture, in which each group comprises at least one light source, and in which the light sources are arranged statically in said hollow space, in which the light sources are arranged inside said hollow space in an essentially dome-shaped configuration.
Thus, a lighting fixture is produced which makes lighting with a great degree of freedom possible. This offers the advantage that, without using mechanical components, one or more different objects can be illuminated at the same time using one or more different groups of light sources. This means that: - either one group of light sources, comprising one or more light sources, can illuminate one object, as a result of which, furthermore, several objects can be illuminated simultaneously by simultaneously installing several groups of light sources; or one object can be illuminated using several groups of light sources. In this case, the groups of light sources may be contained in one lighting fixture, or they may be contained in several lighting fixtures.
In one preferred embodiment of a lighting fixture according to the invention, said essentially dome-shaped configuration of the light sources is achieved by providing an essentially dome-shaped structure which is composed of one or more elements to which the light sources are attached.
In a first, more preferred embodiment of a lighting fixture according to the invention, the essentially dome-shaped structure is formed by two or more elements which are connected to one another and to which the light sources are attached.
More preferably, the essentially dome-shaped structure is in this case formed by two or more small plates which are connected to one another and to which the light sources are attached. In a second, more preferred embodiment of a lighting fixture according to the invention, the essentially dome-shaped structure is composed of at least two elements, comprising - a dome-shaped body which is provided with one or more perforations; at least one supporting element which is connected to said dome-shaped body, and to which said light sources are attached in such a manner that the light from the light sources can pass through said perforations.
In an advantageous embodiment of a lighting fixture according to the invention, the dome-shaped configuration of the light sources is essentially configured in the shape of a segment of a sphere.
This has the advantage that the light emanating from the light sources can pass better through the centre of said opening in the lighting fixture.
In a preferred lighting fixture according to the invention, the light sources are light- emitting diodes.
This has the advantage that a large number of these light-emitting diodes can be incorporated into the lighting fixture, since light-emitting diodes are small light sources.
In order to focus or diffusely spread the emitted light better, the light-emitting diodes are in this case preferably provided with a lens.
In an advantageous embodiment of a lighting fixture according to the invention, the two or more groups of light sources are activated by one or more control modules which cause the various activated light sources to light up.
In a more advantageous embodiment of a lighting fixture according to the invention, the control of the control modules is done by means of a computer. Thus, due to the small number of operational elements, the control modules are governed in a quick, simple and intelligent manner. In addition, it is possible to produce different "light scenes" and it is even possible to change light scene very quickly (even stroboscopically).
The lighting fixture according to the invention may be a built-in lighting fixture which is built into a ceiling and/or wall, or may be a surface-mounted lighting fixture which is directly or indirectly attached to a ceiling and/or wall. An example of a lighting fixture which is indirectly attached to the ceiling is a hanging lamp.
Below, a more detailed description of two exemplary embodiments of a lighting fixture according to the invention is given in order to illustrate the features of this invention further and to indicate the additional advantages and details. It will be clear that nothing in the following description may be interpreted as limiting the scope of protection claimed in the claims for the lighting fixture according to the invention.
Furthermore, some of these embodiments are discussed in the attached figures, in which reference numerals are used to refer to these figures, in which:
Figure 1 shows a cross section of a first embodiment of a lighting fixture according to the invention;
Figure 2 shows a perspective bottom view of a first exemplary embodiment of a lighting fixture according to the invention;
Figure 3 shows a bottom view of a first exemplary embodiment of a lighting fixture according to the invention; - Figure 4 shows a cross section of a second exemplary embodiment of a lighting fixture according to the invention;
Figure 5 shows a perspective bottom view of a second exemplary embodiment of a lighting fixture according to the invention;
Figure 6 shows a bottom view of a second exemplary embodiment of a lighting fixture according to the invention;
Figure 7 shows an arrangement in which four groups of LEDs, each forming part of a different lighting fixture, illuminate the same object;
Figure 8 shows an arrangement in which three groups of LEDs, each forming part of the same lighting fixture, each illuminate a different object; Figure 9 shows an arrangement in which three groups of LEDs, each forming part of the same lighting fixture, illuminate the same object.
A lighting fixture (1,2) according to the invention (as illustrated in figures 1 to 6), comprises a hollow space (10,20) which is provided with two or more groups
(A1A11A21A31A4) of light sources (100). These groups (A1A11A21A31A4) of light sources
(100) are provided for lighting one or more objects (200) through an opening (11,21) in the lighting fixture (1,2) (as illustrated in figures 7 to 9). Each group
(A1A11A21A31A4) of light sources (100) in this case comprises at least one light source (100), and is statically arranged in said hollow space (10,20). That is to say that the light sources (100) cannot be moved (directed) mechanically. The light sources
(100) inside said hollow space (10,20) are arranged in an essentially dome-shaped configuration, as a result of which, as has already been mentioned above, a lighting fixture (1 ,2) is produced with a high degree of freedom of lighting, and in which one or more different objects (200) can be illuminated simultaneously using one or more different groups (A1A11A21A31A4) of light sources (100) without the use of mechanical components. That is to say that either, as illustrated in figure 8, one group of light sources (A)1 comprising one or more light sources (100), can illuminate one object (200), as a result of which, furthermore, several objects (201,202,203) can be illuminated simultaneously by simultaneously installing several groups of light sources (A11A21A3); or, as illustrated in figures 7 and 9, one object (200) can be illuminated using several groups of light sources (A11A21A31A4). In this case, as illustrated in figure 9, the groups of light sources (A11A21A3) may be mounted in one lighting fixture (1,2), or these light sources (A11A21A31A4) may be mounted in several lighting fixtures (1,2) , as illustrated in figure 7.
The dome-shaped configuration of the light sources (100) is preferably produced by providing an essentially dome-shaped structure (12,22) which is composed of one or more elements (13,23,25) to which the light sources (100) are attached.
In the first exemplary embodiment, as illustrated in figures 1 to 3, the essentially dome-shaped structure (12) is formed by two or more elements (13) connected to one another. Preferably, these elements consist of small plates (13) connected to one another to which the light sources (100) are attached. In the exemplary embodiment as illustrated in the figure 1, the small plates (13) are designed as small flat T-shaped plates connected to one another. However, the small plates may also have any other possible shape.
In the second exemplary embodiment, as illustrated in figures 4 to 6, the essentially dome-shaped structure is composed of at least two elements, comprising an essentially dome-shaped body (23) which is provided with one or more perforations (24); at least one supporting element (25) which is connected to said dome-shaped body (23), and to which said light sources (100) are attached, in such a manner that the light of the light sources (100) can pass through said perforations (24).
In the exemplary embodiment of a lighting fixture (2) as illustrated in figure 4, one light source (LED) (100) is provided per perforation (24). The LED (100) is in this case arranged on a supporting element (25) and this supporting element (25) is connected to the essentially dome-shaped body (23) via a cone (26) through the perforation (24). However, there may also be several light sources (100) per supporting element (25), as a result of which the light of the several light sources (100) passes through one perforation (24).
In the exemplary embodiment of a lighting fixture (2) as illustrated in figure 4, the supporting elements (25) are at equal distances to the perforations (24). However, the distance between a supporting element (25) and a perforation (24) may be arbitrarily selected retrospectively.
In both exemplary embodiments of a lighting fixture (1 ,2) as illustrated in figures 1 to 6, the essentially dome-shaped configuration is essentially configured in the shape of a segment of a sphere, as a result of which, as has already been mentioned, the light emanating from the light sources can pass better through the centre of said opening in the lighting fixture (1 ,2). The light sources (100) are preferably light-emitting diodes (LEDs). These light- emitting diodes are preferably provided with a lens (not illustrated in the figure) for focusing or diffusely spreading the emitted light.
The two or more groups of light sources (A, A1-A4) are activated by one or more control modules which cause the various activated light sources (100) to light up. These control modules activate one or more switched, intelligent supply modules which provide the required power for the light sources (LEDs).
Control of these control modules is preferably done by means of a computer.
The lighting fixtures (1,2) as illustrated in figures 1 to 6 are lighting fixtures (1,2) which may be used as built-in lighting fixture for a ceiling and/or wall. An opening is made in the ceiling and/or the wall corresponding to the opening (11,21) of the lighting fixture (1,2). The toothed section around the opening (11,21) is plastered, in order not to be visible.
However, the lighting fixtures may also be used as a surface-mounted lighting fixture which is attached directly or indirectly, for example via a hanging lamp, to a ceiling and/or wall.
