Description

The invention relates to a luminaire with a plurality of bulbs and with a plurality of reflectors, a kit for producing such lights and a reflector for such a lamp.

Luminaires with a variety of lamps and downstream optical elements such as reflectors and refractors are known, for example from the DE 10 2009 044 387 A1 , By the lamps and downstream optical components, a predetermined light intensity distribution can be achieved.

A disadvantage of this known lamp, however, is that they can be delivered only with great effort with different light intensity distributions or adapt to different lighting situations. In addition, with such luminaires when using white LEDs as illuminants visible angle-dependent color deviations may arise, which are due to the radiation behavior of the white LED, and passed through the interaction of LED and optical element or amplified.

The invention is therefore an object of the invention to provide a lamp that allows to illuminate a predetermined effective area exactly, without it comes to visible color deviations when using white LED bulbs, and can be easily adapted to different lighting tasks.

This object is achieved by a lamp with a plurality of directed in a direction of illumination radiating bulbs and with a plurality of reflectors, which are opposite the bulbs in the direction of light, solved, the bulbs and the reflectors are structurally combined in a housing. The lamp thus differs, for example, from known street lamps, in which a single reflector is arranged outside the housing in order to reflect the light of one or more lamps towards the street.

The fact that in the solution according to the invention, the reflectors are in the direction of light opposite the bulbs and not, as usual, the bulbs are surrounded by the reflectors, on the one hand, the reflectors can be replaced easily. On the other hand, this arrangement, together with the directional radiation of the lighting means, enables a flexibly adaptable, exact alignment of the individual light intensity distributions. The entire light intensity distribution of the luminaire results from the superimposition of the luminous intensity distributions of the individual reflectors.

The invention can be further improved by the following, arbitrarily combinable and each advantageous embodiments.

Thus, at least one LED or a nest with several LEDs is preferably used as the light source. In order to increase a directional radiation and thus the light output at the reflector or keep the reflector as compact as possible, and to implement the light mixture in the case of a white LED, the light source is preferably provided with a bundling optics, in particular a collimator. The collimator optics leads to a deflection of all light components emitted by a white LED in one direction, wherein the angle-dependent color deviations of the LEDs are largely compensated for by mixing these components.

The lamp is preferably a compact lamp, as it can be used to illuminate streets and / or facades, but also for the illumination of interiors. Typical dimensions of the reflectors are therefore preferably less than 15 cm or less than 10 cm or even 5 cm, so that the lamp has compact dimensions. In the housing can be united between two and twenty lamp-reflector combinations. The bulbs and the reflectors are spaced apart. The distance between the light sources and the respective associated reflectors can be between 1 cm and 10 cm, preferably between 2 cm and 5 cm.

In order to achieve desired luminous intensity distributions and to improve color uniformity when using white LEDs as illuminants, the reflector surface may be completely or partially faceted. The reflector surface can be provided with elevations and depressions. The elevations and / or depressions may be configured pillow-shaped, groove-shaped or honeycomb-like, with a round or polygonal, for example, four- or hexagonal base surface. The size of these structures is preferably less than 5 mm. The surface texture of the non-white, partially white or completely faceted reflector surface can be designed to be highly reflective or diffuse in different gradations from light to highly diffuse.

The individual lamps of the lamp can have different colors to allow special color effects in the luminous intensity distribution of the lamp. For example, a particular object or a specific area within the luminous intensity distribution of the luminaire may have a different color be illuminated when the reflector associated with a different color bulb is aligned with this object or this area.

Each illuminant is preferably associated with exactly one reflector, which deflects the light generated by the illuminant. However, other illuminant-reflector combinations are possible. Thus, for example, a plurality of bulbs on a reflector or it may be a light source directed to multiple reflectors.

According to a further advantageous embodiment, at least some reflectors of the lamp can be configured identically. At least some reflectors can have a radiation direction, that is to say radiate or concentrate the light in a directed manner. At least some reflectors may have a focal point. For this purpose, the reflector surface may have a concave curvature, in particular a parabolic curvature. By way of example, the light cone reflected by a reflector when light is incident in parallel can have an opening angle between 20 ° or 50 °. The cone of light does not necessarily have a strict conical shape, even oval or slit-shaped light cone are possible, for example. Of course, other embodiments of the reflectors are possible to solve a variety of lighting tasks.

Each reflector preferably reflects the light incident from the illuminant at a slightly blunt to acute angle.

At least some reflectors can be oriented differently, ie reflect the light relative to the associated light source in each case in different directions, so that the light intensity distribution of the lamp from the individual light intensity distributions of the reflectors can be assembled.

The reflectors are preferably separate components that can be movably, interchangeably and / or repeatedly detachably fastened to the luminaire. In particular, at least some reflectors can be arranged to rotate relative to one another. By a simple rotation of the reflectors results in the least constructive effort already a different light intensity distribution.

According to a further advantageous embodiment, at least some reflectors can be designed to be rotatable about mutually parallel axes of rotation and / or arranged twisted. In this way, it is possible to align the reflectors by simply turning. A given light intensity distribution can be composed by a simple adjustment of the reflectors from their individual light intensity distributions.

The lamp can be designed so that the reflectors are aligned in the mounted state. Thus, the light does not have to be disassembled to adjust the overall light intensity distribution.

The reflector surface or an imaginary plane of equalization laid through the reflector surface preferably extends obliquely to the axis of rotation. The level of compensation can be calculated by averaging, for example arithmetic or geometric averaging of the reflector surface.

When viewed from the light source, the reflector is preferably circular in order to completely capture the light cone of the light source.

According to a further advantageous embodiment, at least one reflector holder for at least one reflector can be provided on the reflector, in which the at least one reflector can be fastened in different angular positions in the luminaire offset relative to one another about an axis of rotation. In this embodiment, the light intensity distribution of a reflector is adjusted by attaching the reflector in one of the discrete angular positions. In this case, at least one position of the reflectors within the lamp several different angular positions or at the different positions of multiple reflectors only one angular position, but which differs from position to position, may be specified.

The reflector holder, for example, have a reflector and / or bulb-side approach, which is used in a corresponding complementary configured recording. For continuous rotatability approach and / or recording may have a circular cross-section and form a sliding bearing. Discrete angular positions can be achieved, for example, via a polygonal or star-shaped projection and / or recording. Furthermore, form-locking elements may be provided, such as index pins, which cooperate with correspondingly complementary form-fitting elements, for example holes for receiving the index pins, and which define at least one angular position of the reflector. The reflector holder can also have a flange which can be screwed or riveted into different angular positions.

In order to pack the bulbs and reflectors as close together as possible, the axis of rotation preferably runs parallel to the direction of illumination. So that the reflectors do not emanate from the light cone of the respective associated illuminant during a rotation about the axis of rotation, the axis of rotation preferably runs concentrically to the light cone of the luminous means.

The lamp, in particular the housing, may have a light exit opening, through which the light reflected by the reflectors emerges from the lamp. The luminous directions of the lamps extend in such a configuration preferably parallel to the light exit opening. This orientation allows the greatest freedom for the adjustment of the reflectors.

In an alternative embodiment, the luminaire may have at least two light exit openings, which are arranged at an obtuse or acute angle, for example, or at right angles to each other and / or face each other, so that the luminous means and the reflectors are arranged between at least two light exit openings. A light exit opening can also be arranged on an end face or end face of the luminaire. A luminaire configured in this way allows a light emission over a larger angular range.

The light rays reflected by the reflectors preferably exit at a slightly obtuse to acute angle from the light exit opening.

The light exit opening is preferably designed to be continuous and in particular has no interruptions.

The illuminant-reflector combinations of the luminaire can be arranged side by side, in particular along a straight line. The line preferably extends perpendicular to the direction of illumination of the bulbs in order to achieve the most dense packing and compact design with simple power supply of the bulbs. At least some lamps can be arranged on a common supply strip.

The luminaire or the housing may, in a further advantageous embodiment, have a luminaire space for accommodating the plurality of luminous means and reflectors. The luminaire space can be elongated, wherein the longitudinal direction preferably extends perpendicular to the direction of illumination. In particular, at least some lighting means can be arranged on one side and at least some other lighting means on the other side of the lighting space. A uniform over a wide beam angle illumination can be achieved when on the one side of the lamp space both some reflectors and some bulbs and also on the other side of the lamp space both some reflectors and some bulbs are arranged. This makes it possible to radiate the reflected light on both sides of the lamp at shallow angles. Between the bulbs and the reflectors of the lamp space can form a preferably continuous gap.

In order to increase the luminous efficacy, the luminaire room can be mirrored at least in certain areas.

The invention relates not only to a single luminaire but also to a kit with which several luminaires can be put together to fulfill a wide variety of lighting tasks. Such a luminaire manufacturing kit as described above may include a plurality of interchangeable reflectors having different radiation characteristics. Depending on the desired light intensity distribution, the reflectors necessary for their generation can be combined. If, for example, a luminaire is required which is to provide a uniform backlighting and at the same time a particularly bright zone at a certain point in the area illuminated by the backlighting, at least one reflector with a spot characteristic can be used to generate the bright zone, while in FIG Incidentally, rather wide-radiating reflectors are used, which serve to produce a homogeneous illumination of the background.

Finally, the subject matter of the invention is a reflector as used in a luminaire or the kit described above. Such a reflector may have a substantially disc-shaped reflector surface and a fastening device for mounting the reflector preferably in different angular positions in a lamp, in particular a lamp in one of the embodiments described above.

The reflector surface may be designed disk-shaped. It may also protrude beyond the attachment means. The reflector as a whole can be mushroom-shaped. As already stated above, the fastening device can be designed in the form of a lug or as a receptacle for a light-side approach. The approach and / or the recording may have a circular, polygonal or star-shaped cross-section. The reflector may be provided with positive locking elements, which allows mounting of the reflector only in certain angular positions.

The projection and / or the receptacle extend away from the reflector surface.

The reflector surface preferably extends obliquely to the direction of illumination in the luminaire or at an angle to the projection and / or the receptacle. This makes it possible to change the emission direction of the reflector by simple rotation about the axis of rotation.

In the following, the invention is explained by way of example with reference to different embodiments with reference to the accompanying figures. The embodiments described here can be changed in accordance with the above statements. If, for example, in the case of a particular embodiment, there is no element and its technical effect, then this element can be omitted. An element whose effect is necessary for a particular application may also be added to the described and illustrated embodiment.

For simplicity, the same reference numerals are used in the figures for elements that correspond to each other in structure and / or function. In the description of the individual embodiments, only the differences from the previous embodiments are discussed, unless otherwise explained. Incidentally, the remarks on the previous embodiments apply in each case.

First, structure and function of a lamp according to the invention 1 based on 1 described.

The lamp 1 has a plurality of bulbs 2 on, with the individual bulbs 2 preferably not omnidirectional in all directions, but directed in a direction of illumination 3 radiate. As a light source 2 For example, at least one, in particular white, but also differently colored, for example, also multi-colored LED 4 with a collimator optics 5 into consideration. The collimator optics 5 causes the rays of light to roughly parallel the bulb 2 in lighting direction 3 leave, as by the arrows 6 is shown schematically.

In lighting direction 3 the bulbs 2 lie opposite, preferably separated by a gap in the lamp 1 reflectors 7 , As 1 shows, every bulb can 2 exactly one reflector 7 be assigned. A reflector surface 8th of the reflector 7 is the light source 2 exactly opposite. The reflector surface 8th may be completely or partially with a textured surface 9 be provided, for example, a faceting. The structured surface 9 may be from surveys or depressions 10 be formed. The structures 9 the reflector surface 8th can pillow, grooved and / or honeycomb-shaped and have a round or polygonal, for example, four- or hexagonal base. The reflector surface 8th can be highly reflective or formed in different gradations of light to strong diffuse reflective. The reflector surface 8th is designed to effect desired luminous intensity distributions and color uniformity enhancement when using white LED as the illuminant.

One through the reflector surface 8th level of equalization 11 is opposite the direction of light 3 inclined, so that the reflector allows a deflection of the beam path in an acute to slightly obtuse angle. The compensation level 11 can be determined, for example, by arithmetic or geometric averaging. The reflector surface 8th can, depending on the radiation characteristics of the reflector 7 be curved convex or concave. Depending on the curvature of the reflector surface 8th result in different emission characteristics, in particular with respect to a beam expansion of the reflectors 7 reflected radiation. The curvature of the reflector surface 8th affects those of a single reflector 7 generated light intensity distribution. In 1 is schematically a reflected cone of light 12 shown. Depending on the light source and radiation characteristics of the reflector surface 8th can the light cone 12 deviate from a strict conical shape and be for example oval or lenticular.

The individual light cone 12 the majority of reflectors 7 overlap to a light intensity distribution 13 the light 1 , The shape of the light intensity distribution and the intensity distribution in the light intensity distribution are determined by the number, the orientation and / or emission characteristic of the reflectors 7 ,

The reflectors 7 the light 1 can be identical or different. So can the individual reflectors 7 Next Different emission characteristics and different radiation directions 14 exhibit.

In a particularly simple and at the same time versatile design, the light 1 identical reflectors 7 on, which are only differently oriented. The orientation of the reflectors is particularly simple 7 if only around a rotation axis 15 are twisted against each other. As in 1 Shown is the axis of rotation 15 parallel to the lighting direction 3 run. It is particularly advantageous if the axis of rotation 15 coaxial with the axis of the bulb 2 generated light cone 12 is aligned so that the reflector 7 upon rotation about the axis of rotation 15 not from the cone of light 12 of the bulb 2 can hike. The double arrow 16 indicates schematically how the reflector 7 around the axis of rotation 15 can be turned.

Of course, another orientation of the axis of rotation is 15 possible. For example, the axis of rotation 15 perpendicular to a floor 17 or a light exit surface 18 through which the of the reflectors 7 reflected light 12 exit. The light exit surface 18 is preferably the ground 17 opposite and runs parallel to this. The floor 17 can be provided with a reflective layer or polished to increase the luminous efficacy of the luminaire.

A different orientation of the reflectors 7 in different angular positions 19 can be reached when the reflector surface 8th or the compensation level 11 obliquely to the axis of rotation 15 and the direction of the light 3 runs.

Of course, also differently designed reflectors 7 be arranged rotated to each other, if this for the compilation of a predetermined light intensity distribution 13 necessary is.

The reflectors 7 are about the axis of rotation 15 continuously rotatable or mountable only in discrete angular positions. The reflectors are preferred 7 detachable, in particular repeatedly detachable, in the luminaire 1 attached, leaving an orientation of the reflectors 7 also with mounted light 1 still possible on site.

The bulbs 2 and the reflectors 7 are structurally in a housing 20 united, which is a support structure for the bulbs 2 and reflectors 7 forms. The lamp 1 is compact and is used to illuminate streets, squares, facades and / or interiors. The dimensions required for this purpose are small, so that the reflectors have a diameter of less than 15 cm, in particular even less than 10 cm or less than 5 cm.

The lamp 1 can be elongated, with the longitudinal direction 21 preferably perpendicular to the direction of illumination 3 runs. The light exit surface 18 is preferably also elongated and runs parallel to the light directions 3 the bulb 2 ,

The bulbs 2 and the reflectors 7 can on the long sides 22 of the housing 20 be arranged, with the long sides 22 obliquely or perpendicular to the light exit surface 18 can run.

The bulbs 2 and the reflectors 7 can in a lighting room 23 be included, which may be substantially cuboid, in particular in the form of an elongated cuboid, configured. The lighting room 23 can from the long sides 22 as well as from the ground 17 and the light emitting surface 18 be limited. The lighting room 23 can be down to the light exit surface 18 have reflective surfaces.

In the half-space 24 that differs from the bulbs 2 Seen from beyond the light exit surface 18 located one over the entire elevation angle 25 To allow even lighting, it may be useful to have at least some bulbs 2 on one long side 22 and at least some bulbs 2 on the other long side 22 of the housing 20 to arrange. One possibility for such an arrangement is that on one longitudinal side 22 alternately a bulb 2 and a reflector 7 are arranged.

The lamp 1 can be made up of individual modules 26 be constructed, each having a plurality of paired bulbs 2 and reflectors 7 structurally unite and in the housing 20 be assembled, for example by placing them on a common holder 27 be attached.

In 2 is a further embodiment of a lamp according to the invention 1 shown. It differs only in that all bulbs 2 on one longitudinal side of the housing 22 and accordingly the reflectors 7 on the other long side 22 are arranged. This lamp can also be made of modules 26 be constructed. In particular, it is with the help of in 2 illustrated modules 26 in which the bulbs 2 on only a single longitudinal side 22 possible, by a 180 ° around a perpendicular to the light exit opening 18 extending axis 28 turned installation a light 1 put together, at the back of some bulbs 2 on one and some bulbs 2 on the other long side 22 to find oneself.

Incidentally, the structure and function of the luminaire correspond 1 of the 2 those of the lamp 1 from 1 ,

3 shows a lamp 1 in the in 1 illustrated design in a surrounding housing 29 , In the enclosure 29 can the light 1 be installed in, for example, masts or other support bodies (not shown). Alternatively or additionally leaves a suitably designed surrounding housing 29 also the use as hanging pendant lamp, floor recessed or -aufbaustrahler.

In the foregoing embodiments, the lighting directions are 2 the bulb-reflector combinations 30 aligned parallel to each other, so that a rectilinear arrangement of the bulbs 2 together with the assigned reflectors 7 results. Of course, this arrangement can also be circular or along another closed contour, for example with a radially extending illumination direction 3 , or along an arbitrarily guided line.

4 shows a reflector 7 with the reflector surface 8th and a fastening device 31 with which the reflector 7 at the light 1 can be attached. In a simple way, the attachment of the reflector 7 by a positive connection, for example by clipping. For this purpose, the fastening device 31 of the reflector a positive connection element 32 in the form of, for example, a recess 33 on. Instead of or in addition to a recess can of course also be provided a latching tongue. Other types of fastening used in the fastening device 31 may be provided, for example, screw, bayonet, clamp connections, etc.

The fastening device 31 can in the form of a particular stubby approach 34 be configured, which extends away from the reflector surface. Opposite the direction 35 in which the approach 34 extends, is the level of compensation 11 at an acute angle 36 inclined. The direction 35 can the lighting direction 3 and / or the axis of rotation 15 correspond.

Good is in 4 also the faceting of the reflector surface 8th through a pillow-shaped surface structure 9 to recognize.

The reflector surface 8th is from a disc-shaped section of the reflector 7 educated. On one side 37 of the approach 34 can the reflector surface 8th further from the beginning 34 extend away than on the other side. When installed, one side 37 the ground 17 and the other side 38 the light exit surface 18 to be facing.

As 5 shows, the reflector can 7 on an adapter 39 put on and with the adapter 39 positively, for example via the at least one positive locking element 32 be connected. The adapter 39 But it can also be monolithic with the reflector 7 be designed. The adapter 39 can be a guide element 40 have, for example in the form of a projection or a recess which cooperates with a complementary guide element of the reflector and an assembly of the reflector 7 on the adapter 39 allowed in only one position. The guide element 40 thus forms a Fehlstecksicherung.

The adapter 39 serves to fix the reflector 7 in several different angular positions about the axis of rotation 15 ,

If it is desired that the reflector 7 in only a limited number of discrete angular positions about the axis of rotation 15 around in the light 1 can be mounted, at least one index device 42 be present, which has the form of a form-fitting element, for example a projection or a recess.

In 5 are only for purposes of example two in the direction of the axes of rotation 15 projecting index pins 43 shown. Alternatively, the index facility 42 also between the reflector 7 and the adapter 39 be formed, or without adapter directly between the reflector 7 and index facility 42 ,

The index facility 42 works with a in 5 not shown complementary device of the lamp together. The angular position of the luminous index device determines the angular position 19 in which the reflector 7 is mounted.

This is below based on the 6 explained.

In 6 is shown as the luminaire side of the index device 42 at the different positions of the reflectors 7 around different angles of rotation 44 around the axis of rotation 15 can be arranged twisted. In 6 is the luminaire-side part of the index device 42 complementary to the two index pens 43 designed and has two receiving openings 45 for the two index pens 43 on. The position of the two receiving openings 45 determines the angular position 19 the reflectors 7 ,

As 6 Furthermore, the luminaire-side part of the indexing device can 42 at a supply bar 46 be formed, at the same time solder joints 47 for attaching the bulbs 2 , especially the LEDs 4 having. In order for both in 1 as well as the in 2 shown embodiment, the board has 46 at each position both a solder joint 47 as well as an index facility 42 on. Thus, in any position optionally a reflector 7 or a light source 2 be attached. For example, in the embodiment of 1 and 3 alternately a solder joint 47 provided with an LED and a reflector 7 assembled. In the embodiment of 2 are each on a supply bar 46 either only bulbs 2 or just reflectors 7 appropriate.

The design of the 6 Allows for default lighting situations or luminous intensity distributions 13 pre-assembled positions for the reflectors 7 provided. For this purpose, prefabricated supply strips 46 used.

7 shows the attachment of a reflector 7 in the light 1 , It can be seen how the index device 42 Reflector side and lightside cooperates to the reflector 7 to position in a predetermined angular position.

The reflector 7 is on the adapter 39 fixed form fit, for example by locking tongues 48 in the recesses 33 are engaged.

The adapter 39 can a shoulder 49 in the form of an annular bead 50 have, on which a hold-down 51 rests. The hold down 51 is with a reflector opening 52 provided, through which the reflector 7 or the adapter 39 extends and within the reflector 7 or the adapter 39 can be accommodated in different rotational positions.

On the adapter 39 Different reflectors can be attached when the lamp is fully assembled. If, for example, reflectors with a narrow radiation characteristic are used instead of reflectors with a broad emission characteristic, then the luminaire can simply be used for illuminating nearer objects without having to change the orientation of the reflectors.

Instead of discrete positioning by means of an index device 42 can of course also a continuous adjustability of the reflectors 7 around the axis of rotation 15 be provided. For example, the angular position of a reflector can be determined by frictional engagement. In the embodiment of 7 This can be achieved by dispensing with the index pins and securing the reflector only via the hold-down device.

According to a further embodiment of the lamp 1 as they are in 8th can be shown instead of the soil 17 ( 1 ) another light exit surface 18 ' be provided by the individual reflectors 7 Reflect light. The bulbs 2 and the reflectors 7 are in this embodiment between the two light exit surfaces 18 . 18 ' arranged. As in the embodiment with only one light exit surface 18 Can the reflectors 7 reflected light rays and the second light exit surface 18 ' pass in a slightly blunt to acute angle. The two light exit surfaces 18 . 18 ' need not be parallel to each other, but may also be inclined to each other or arranged at right angles to each other. For example, a light exit surface 18 ' also on one or both ends 55 be arranged the lamp.

These embodiments allow a light emission through at least two sides of the housing, without the arrangement of the bulbs 2 and reflectors 7 must be changed. There are only a few reflectors 7 turned so that they light the lamps assigned to them 2 through the at least one further light exit opening 18 ' reflect.
