Description

field of invention

The present invention relates to lights with mechanical light radius control.

Background of the invention (and prior art)

A lamp, technically also luminaire, is a device in which a light source is permanently installed or can be installed reversibly and which is used for lighting. There are different types of lights, such as ceiling lights (as ceiling arches and ceiling crowns), wall lights (as bar lights), table lights (like desk lights), standing lights or street lights. They can be permanently installed or mobile. They can be operated electrically from the mains, with accumulators or batteries, but also with gas.

When planning lighting in general and lighting systems in particular, various photometric quality features must be taken into account. These include, for example, parameters such as light direction and light control, luminance distribution, illuminance, glare limitation, light direction and shading as well as light color.

In this context, it is usually problematic that a lamp, as soon as it is first assembled and permanently installed, regardless of its light source and its potential electronic adjustability, can hardly or not at all be changed with regard to the parameters mentioned. Known lights and systems therefore lack variability with regard to the parameters mentioned and in particular in light control, light utilization in general and with regard to mechanical control of the beam angle and lighting radius of an already installed light in particular.

Detailed description of the invention

In the present description, the terms top, bottom, right and left and similar information refer to the orientations or arrangements shown in the figures and only serve to describe the exemplary embodiments. These terms may indicate preferred arrangements but are not meant to be limiting.

Furthermore, the expressions “substantially”, “approximately”, “approximately” and similar expressions mean that deviations of +/-10%, preferably +/-5%, from the stated value are permissible.

Candela (cd) is the unit of measure for luminous intensity (luminous flux per solid angle). The smaller the angle, the greater the directivity and candela value. Lumen (Im) is the unit of measurement of luminous flux. Luminous flux is the total amount of light emitted by a lamp. Lux (Ix) is the unit of measurement for illuminance E. This reflects the intensity with which a surface is illuminated. If 1 lumen falls homogeneously on an area of 1m ² , then E = 1 Ix = 1 lm/m ² .

The term beam angle is used below to describe one aspect of the directivity of light sources. The directional characteristic means the angle-dependent luminous intensity (which is measured in candela). It is used, on the one hand, to assess the illumination of surfaces or, on the other hand, the glare of the light source.

In the case of directional light sources (which also includes LEDs), the beam angle means that Angle that is enclosed by the lateral points with which the light radiates from the illuminant with half the maximum light intensity. For this reason, the beam angle is also referred to as the half-value angle. In other words: The beam angle provides information about the angle at which the light is emitted. This applies equally to luminaires that are suspended, for example from a ceiling or a suspension structure, standing or otherwise attached, for example by means of clamps, in the room to be illuminated.

Furthermore, in the following, the term “light radius” designates the general emission or form of emission of light that a lamp generates according to the present disclosure. Depending on the embodiment set out below, the lighting radius is variable. The radiation emanates from at least one light source and is guided or controlled by means of other mechanically reversible components of a lamp. The corresponding steering or light guidance of the original light cone relates to the desired three-dimensional geometric shape of the light radius. Control relates to the amount and quality of light emitted. In this context, a geometric distinction is made below between lateral portions of the luminous radius and portions of the luminous radius in the emission direction of the luminous medium or luminous media.

the 1 shows a schematic side view and a sectional view AA of a carrier body (3) of a carrier device for a lamp according to an embodiment of the present invention. As 1 can be seen, the carrier device has a carrier body (3) which is preferably rotationally symmetrical to the line of intersection AA. As the sectional view shows in particular, the carrier body (3) is made in one piece here. However, it can also (not shown) be composed of several individual parts. In addition, the carrier body (3) has different geometric sections both on its inside and on its outside, which can be cylindrical, bulbous, conical, slanted, stepped and the like.

the 2A shows a side view of a support device (1) for a lamp according to an embodiment of the present invention. the 2 B and 2C show two isometric views of the in 2A illustrated carrier device (1).

The carrier device (1) according to 2A has a carrier body (3) which has an upper part (5), at least one middle part (7) and a lower part (9) and an optional further part (10) on the lower part (9), and at least one lamp holder or version (11). In 2A an illuminant (12) is also reversibly fixed in the illuminant receptacle (11). Optionally, the lighting means (12), for example in the case of one or more LEDs, can also be firmly anchored, for example cast in the material of the carrier device (1). Furthermore, there is the lamp holder (11) in the 2A on the lower part (9) of the carrier body (3). Optionally, the lamp holder (11) can be provided either instead or additionally on the upper part (5) or on the lateral edges of the carrier device (1).

Furthermore, the carrier body (3) of the carrier device (1) is in 2A in the form of a coil, the upper part (5) tapering towards the middle part (7) and the lower part (9) widening away from the middle part (7). In addition, the middle part (7) has at least one barrel-shaped and/or cylindrical section. The further part (10) is preferably cylindrical in shape, but can alternatively taper slightly conically inwards with respect to the center of the illuminant (12) or open conically outwards. The carrier body (3) is preferably designed to be rotationally symmetrical or elliptical. The carrier body (3) is also preferably cast in one piece for production reasons or milled or turned from solid material. Alternatively, the carrier body (3) can consist of at least two elements, the at least two elements of the carrier body (3) being plugged into one another, screwed or glued together or vulcanized. Alternatively, the central part (7) in particular can be designed in several parts. Depending on the type of arrangement selected for the respective parts or division, the at least two elements optionally have complementary arrangements of screw, snap-in, adhesive and/or plug-in connections at the top, bottom, right, left or side of the carrier body element.

The carrier body (1) can be made of plastic, in particular Plexiglas, or metal. In this context, the use of electrically non-conductive plastic has the advantage that any insulation between the carrier body (1) and all cables or the power connection (13) can be dispensed with. The use of a translucent plastic is preferred, since in this case the amount of light emitted by the illuminant can be used particularly effectively within the scope of the luminous radius control according to the invention.

Preferably, the carrier device (1) of 2A continue to have a power connector (13). This can be in the form of a connection option for be formed one or more power cables. Alternatively, the power connection (13) can be designed for battery or rechargeable battery operation, with or without a charging station, or wireless power supply, for example via NFC (Near Field Communication).

The carrier body (3) preferably has a groove (15) between the upper part (5) and the middle part (7) and/or between the middle part (7) and the lower part (9).

the 2 B and 2C show isometric views of the carrier device (1) according to 1A . In particular, the 1 B and 1C different views of the illuminant used as an example (12). The lamp (12) is preferably flush with the further part (10). Furthermore, the illuminant (12) is preferably sunk in the carrier body (1) in such a way that the further part (10) is not covered or hidden by the illuminant (12).

3 shows a further side view of the carrier device (1) of 2A , wherein rings (17) made of flexible material have been placed on the middle part (7). In particular, there are two optional narrow or inner rings (17a), for example O-rings, in the optional grooves (15) of the carrier device (1), the groove diameter, tolerances and surface quality being selected in such a way that the narrow rings (17a) only have minimal to no play. However, the carrier device (1) of the present invention can also be used without or with only such a narrow ring (17a).

the 3 Figure 1 also shows two optional central rings (17b) of flexible material of medium diameter and medium strength, such as O-rings, loosely resting on the central part (7) of the carrier device (1). However, the carrier device (1) of the present invention can also be used without or with only such a central ring (17b).

In addition, the 3 an outer ring (17c) with the largest diameter and at least medium, preferably largest thickness, for example an O-ring, which rests loosely on the central part (7) of the support body (3) and is required to have a lamp according to 4 until 6 to assemble. Alternatively, the ring (17c) can also have a smaller thickness than a described ring (17b) with a medium thickness.

the 4 until 6 show a lamp (20) with a carrier device (1) as an example in connection with 1 , 2A until 2C and 3 described. The lamp (20) of 4 until 6 also has a large number of rods (22), at least one ring (17) made of flexible material, for example an O-ring, at least one illuminant (12) and a holder (24).

In addition, the carrier body (1) is preferably made in one piece with the holder (24) with strain relief. The strain relief is on the bracket (24), for example, on the side 2A - 2C seen in the form of a hub screw. Other forms of strain relief are possible, such as S-shaped wraps, presses, clamps, tongue and groove fits, etc.

the 4A until 4F each show a side view of a partially assembled lamp according to an embodiment of the present invention, wherein the degree of assembly of 4A until 4F gradually increasing. Especially 4F shows the attachment or build-up or application of an optional second layer. The layering suggested here, ie with opposing bars, is optional. Equally, parallel layering (not shown) of the rods of the outer layer to the rods of the inner layer is possible.

The carrier device (1) of 4 until 6 has a specific steepness with respect to its flanks, specifically defined over the upper part (5), the middle part (7) and the lower part (9) of the carrier body (3). All three parts are designed to work together geometrically to ensure that the multiplicity of rods (22) rest as linearly as possible on the carrier device (1). An increased degree of linear fit can help increase the stability of the lamp (20) when assembled.

Optionally, the carrier device (1) has a plurality of notches in the upper part (5) and/or in the lower part (9) of the carrier body (3) for optionally controlling and/or fixing the position of at least one layer of rods (22), preferably an inner layer.

The individual bars of the plurality of bars (22) of the exemplary lamp (20) of 4 until 6 consist of an at least partially opaque material and/or an at least partially translucent material. By choosing the material or specific material combinations with different light permeabilities, in particular targeted opacity, it is possible to advantageously control the lateral radiation components of the luminous radius of the lamp (20). In this context, the use of rods made of wood and/or plastic and/or glass and/or Plexiglas and/or metal and/or carbon is recommended. The rods act in their entirety preferably selectively as light-directing elements. The assembly of the rods from the plurality of rods (22) within the lamp (20) in their overall arrangement is variable in that they can be exchanged at any time, ie during the assembly of the lamp (20) and, if desired, even in the assembled state can become. Correspondingly, in particular the lateral radiation component of the lighting radius of the lamp (20) can be configured and adjusted reversibly at any time.

The plurality of rods (22) is also preferably tapered, pointed and/or beveled at at least one end. This facilitates the threading of the rods when assembling the lamp (20), for example according to 4A until 4F , and increases the service life of the at least one ring (17) made of flexible material. In addition, such a shape of the rods improves the conduction or deflection of light if the material of one or more rods of the plurality of rods (22) is at least partially translucent.

In order to hold the plurality of rods (22) on the carrier body (3), at least one ring (17) is provided, preferably a ring (17c) with the largest diameter and largest strength as exemplified in connection with FIG 2 shown and described. Designed for example as an O-ring, the at least one ring (17) is set up to hold and/or support each bar of the plurality of bars (22) in at least one layer of bars (22) on the carrier device (1).

At least one additional flexible ring (17) can optionally be used to fix the mounting of the rods of the at least one layer on the carrier body (3) and/or to secure the rods of the at least one layer against slipping on the carrier body (3). In these cases, the at least one further ring (17) is arranged between the carrier body (3) and the rods of the at least one layer.

Alternatively, the at least one further flexible ring (17) can also be provided in order to hold and/or support a large number of rods (22) in at least a first, inner layer of rods (22) on the carrier device (1). In such embodiments, the at least one ring (17) is then arranged to hold and/or support a further plurality of bars in at least one further second layer of bars on the at least one first layer of bars. In these cases, the at least one further ring (17) is arranged between the bars of the at least one first layer and the bars of the at least one second layer. The at least one further ring (17) serves to hold the at least one inner first layer on the carrier body (3) and to non-slip bearing or support of the at least one outer second layer on the at least one first layer of rods.

In a preferred embodiment, the lamp (20) of 4 until 6 preferably at least five flexible rings (17). In a particularly preferred embodiment, these at least five rings (17) comprise two small inner rings (17a) to be positioned in two grooves (15) of the support body (3). They also include two slightly larger rings or middle rings (17b) and a largest or outer ring (17c).

The materials of all flexible rings (17) used must be adapted to the circumstances of the lamp (20) to be assembled. Thus, the adaptation of various parameters of the rings (17) to the material properties of the carrier body (3) and rods can be advantageous in order to ensure not only a stable lamp construction, but also a reversible adaptability of the lamp (20). Corresponding parameters relate, for example, to different strengths, diameters, widths or strengths of the rings (17) and their function purely as a counter bearing between the carrier body (3) and rods, as a counter bearing between inner rods and outer rods and holding means for inner rods or as purely outer retaining rings. In addition, there are both the dimensions and the mass of the rods to be carried or held.

Furthermore, the selected material properties of the rings (17) and the material or materials of the plurality of rods (22) result in a reversible frictional connection between the rings and rods. This allows the position of the rods relative to one another and relative to the rings to be varied or changed by shifting. Preferred holding positions of the rings (17), in particular the at least one middle ring (17b) and the outer ring (17c), with respect to the total length of each individual rod of the plurality of rods (22) are at least half the rod length per rod. The center point of at least half the rod length lies in the center point of each individual rod, which also allows rods of different lengths to be used. Alternatively, the respective end breakpoints are located at the points at which a rod begins to taper. Thus, rods can be moved both up and down in relation to the central part (7) of the support body (3). This is possible both during the assembly of the lamp (20) and with a lamp (20) that has already been assembled. All in all, this results in an adaptation option that can be adapted to any room, both of lateral parts of the lighting radius and of parts of the light radius in the direction of emission of the light source(s) used.

Furthermore, the at least one light source (12) of the lamp (20) is 4 until 6 mounted on the top and/or on the bottom (not shown) of the carrier device (1). All common light sources according to DIN 5039, in particular incandescent, halogen, fluorescent lamps and LEDs, as well as all common screw or plug-in bases, for example a GU10 or a GU5.4 base, can be used in the light source holder. The base or bases themselves are fastened in the carrier body (1) either by means of gluing, pressing in, casting in or screwing in.

The holder (24) of the light (20) preferably comprises means for suspending and/or supporting the light (20), for example for installation as a ceiling or pendant light. Alternatively, the holder (24) of the lamp (20) includes at least one attachment option for a stand, for example for mounting as a floor lamp or clamp lamp. Other exemplary suspension means may consist in providing at least two ears in diametrically opposite positions on the at least one ring (17) of flexible material. Such eyelets offer an optional possibility of latching or hanging a lamp (20) according to the invention in a stand, for example a U-shaped stand, or in a free-floating suspension structure, for example made of steel or wire cables. Said eyelets can be made of the same material as the rings (17) and can be made in one piece with them. Alternatively, they can be threaded in as extra parts. The choice of material amounts to all materials that are suitable to engage in the rings (17) without damaging them.

Optionally, the holder (24) of the lamp (20) has a cover for any holder parts such as ropes and for guiding any (electrical) cables. Alternatively, a suitable power cable can also be used as a holder for the lamp (20).

The present disclosure also relates to a method of assembling a lamp (20) as exemplified in FIGS 4 until 6 shown. For this purpose, at least one flexible ring from a large number of flexible rings is first positioned on the middle part of a carrier body of a carrier device according to the invention. Thereafter, a plurality of rods are positioned between the central portion of the support body and the at least one flexible ring. This is followed by a configuration of the lighting radius of the lamp (20) by repositioning individual rods from the multiplicity of rods. Optionally, the repositioning can be carried out again with a light that has already been assembled. Corresponding parameter and material requirements apply as in connection with the 1 until 6 described.

the 5A , 5B and 5C show side views of other embodiments of the lamp (20), each embodiment showing a different positioning scheme of the plurality of rods (22) on the support body (3). Each mechanical arrangement of the rods results in different radii of light. the 6A shows in this regard an isometric view of another fully assembled one viewed from below, wherein 6B another isometric view of the assembled light fixture of FIG 6A shows with a view from above.

The invention has been described using preferred embodiments, with the individual features of the described embodiments being able to be freely combined with one another and/or exchanged, provided they are compatible. Likewise, individual features of the described embodiments can be omitted if they are not absolutely necessary. Numerous modifications and configurations are possible and obvious to a person skilled in the art, without departing from the idea of the invention.
