Description

The invention relates to a luminaire insert for a luminaire housing, in particular a floor lamp, by means of which a surface emanating from the luminaire housing can be illuminated.

In lighting technology, the task is often to illuminate larger areas, such as house facades or in general "walls" with large external surfaces. For this purpose, it is known to use, for example, at a greater distance from this surface to be illuminated emitter-like lighting devices. In order that such emitter-type illumination devices do not impair the use of a floor area located, for example, in front of a house facade, such emitters can preferably be placed on the underground facade of the house at a fairly small "horizontal" distance from the house facade. Also, lateral arrangements in the field of, for example, at right angles or obliquely to the house facade extending walls or ceiling arrangements are conceivable in which the distance to the house facade can also be chosen sher low.

It is also known to use so-called. Recessed floor lights, which are embedded in a corresponding distance from the house facade in the underground. Accordingly, the lower end portions of a house facade have a much smaller distance from such lighting devices than the upper end portions. This has the consequence that these closer areas of a house facade are illuminated much more intense with uniformly radiating illumination device than the upper end portions of the house facade.

In order to achieve a uniform illumination, it would also be possible to additionally install additional radiator-like lighting devices in the upper area of a house façade so that overall the house façade can be illuminated quite evenly. By this multiple arrangement of spotlights in the floor area and the head of such a house facade, it is also possible to achieve certain lighting effects by different control of the individual spotlights. This means that certain areas of a house facade, for example, can be illuminated differently to achieve certain effects, for example, to highlight certain ornaments or the like. On a house facade.

However, these spotlight-like lighting devices have the great disadvantage that they are not glare-free for the viewer. Part of the luminous flux is always directed in the direction of the viewer, so that this is perceived by the viewer as disturbing. Furthermore, in order to achieve the most uniform possible illumination, it is also possible to place ground spotlights set up on the ground at a slightly greater distance of a few meters to a house façade. However, this has the considerable disadvantage that the emitted luminous flux, for example, by persons located between the ground radiators and the house facade, at least partially obscure the emitted luminous flux, which is always undesirable.

Accordingly, the invention has for its object to provide a luminaire insert for a luminaire housing available, in particular for a floor lamp, by means of which an emanating from the luminaire housing surface can be illuminated, with the closest possible arrangement of this lamp to one of the edge regions of the surface to be illuminated possible should.

The object is achieved according to the invention together with the features of the preamble of claim 1, characterized in that at least two each line-shaped arranged groups of light emitting diodes are provided, which are arranged on a common or separate illuminant carriers and that the groups of light emitting diodes opposite a on or multi-part reflector is provided with one or more reflection regions and that the arrangement and / or orientation of the groups of light-emitting diodes and / or the arrangement and / or orientation of the reflector with his or with its reflection region (s) relative to the groups of light emitting diodes such it is selected that the luminous flux emitted by the one group of light-emitting diodes is reflected by the reflector into a predeterminable region of the surface and that the luminous flux emitted by the other group of light-emitting diodes reflects through the reflector into another predeterminable region of the surface is ktiert.

The inventive design a luminaire insert for a luminaire housing, in particular a floor lamp, provided by means of which it is particularly possible to uniformly illuminate a house facade or other adjacent, approximately parallel to the emitted luminous flux of the luminaire surface. Furthermore, various lighting effects can be achieved by various measures, so that certain areas of the surface to be illuminated appear lightened or darkened.

According to the invention, in particular at least two groups of light-emitting diodes arranged in rows are provided. The light-emitting diodes of this Groups can be alternately arranged side by side or in parallel rows one above the other. The light emission of these LEDs is carried out in the installed state in a direction away from the surface to be illuminated. Accordingly, these LEDs is associated with a reflector opposite, through which the luminous flux emitted by the light emitting diodes "thrown back" on the surface to be illuminated. In order to achieve the most uniform possible illumination of this surface, these groups of light emitting diodes relative to each other and also relative to the reflector are aligned and arranged so that the emitted luminous flux of a group of light-emitting diodes is reflected to a first predetermined area of the surface to be illuminated, said surface For example, the lower portion of a house facade or adjacent wall may be. The second group of light-emitting diodes is arranged and aligned in a different manner such that their emitted luminous flux is reflected by the reflector into another area of the surface to be illuminated. The respective setting with respect to the arrangement and orientation of the groups of light-emitting diodes can be chosen such that the predetermined area adjoin one another or partially overlap the predetermined areas.

By this basic arrangement of the groups of light emitting diodes relative to each other and relative to the reflector, it is thus possible to arrange a lighting device, in particular in the form of a floor lamp, at a relatively small distance to an edge region of a surface to be illuminated, for example a house facade, while still through the different reflections of the light emissions of the LEDs, a relatively uniform illumination of such a surface, in particular in the areas with a greater distance to the lamp insert can be achieved. For this purpose, the reflector may be designed in the manner of a hollow cylinder segment and have different reflection ranges. In this case, the reflection regions can have different radii of curvature, so that light streams emitted by the individual groups of light-emitting diodes in these regions are emitted in different-sized emission angles to the surface to be illuminated.

The radiation angle to surfaces at a greater distance to the luminaire insert or to the lamp is smaller and the radiation angle to surfaces at a smaller distance to the luminaire is correspondingly larger, so that the surface areas of the surface to be illuminated are "illuminated" with approximately the same intensity. Through appropriate modifications of the luminaire insert, a uniform illumination of the entire surface can also be used to achieve different lighting effects.

The emitted luminous fluxes of the groups of light-emitting diodes can in principle impinge on the entire concave inner surface of the reflector. It can also be provided that these luminous flux impinge in different, adjoining or partially overlapping reflection regions of the reflector. In this case, these reflection regions can have different radii of curvature for achieving different light distribution of the incident luminous fluxes, which radii can merge continuously into one another or which are formed predefined against one another.

Further advantageous embodiments of this can be found in the further subclaims.

Thus, it can be provided according to claim 2, that the groups of light emitting diodes are arranged one above the other line by line and that the light flux emitted by the light emitting diodes of each group emits in each case into one of the reflection regions of the reflector. In this case, the rows of light-emitting diodes are offset from each other such that the light emission of a group of light emitting diodes from the reflector or the respective associated reflector area in a region of the surface to be illuminated greater distance with a smaller beam angle and the luminous flux of the other group of LEDs in a range lower Distance from the lamp with a larger beam angle is emitted from the reflector.

Furthermore, it can be provided according to claim 3, that the groups of light-emitting diodes are arranged on separate illuminant carriers and that the illuminant carriers are configured with their respective associated groups of light emitting diodes relative to one another and / or relative to the reflector with its reflector regions adjustable. With this configuration, the groups of light-emitting diodes are in particular separately and independently adjustable relative to the reflector, so that different lighting effects on the surface to be illuminated can be achieved.

Further, it can be provided according to claim 4, that one group of LEDs emits a luminous flux of greater intensity and the other group of LEDs emits a luminous flux with lower luminous intensity and that the luminous flux of greater intensity through the reflector in a region of the surface greater distance from the luminaire insert and the lower intensity luminous flux is reflected by the reflector into an area of the lesser distance from the luminaire insert. By this measure is particularly in connection with different from Reflector outgoing radiation angles of the luminous flux of the groups of light emitting diodes an extremely uniform illumination of the entire surface achievable.

Furthermore, it can be provided according to claim 5 that the groups of light emitting diodes have luminous fluxes with different color temperatures and / or with different colors. As a result, different lighting effects can be achieved. In particular, by the choice of different color temperatures, as is known for example by the terms "warm white" and "cool white", the uniformity of the illumination of a surface can be influenced. For example, "warm white" emitting light emitting diodes can be used to illuminate the areas with a smaller distance to the luminaire insert, while for illuminating areas with a greater distance to the luminaire insert LEDs are used, which radiate a "cold white" light. Since the reflection intensity of "warm white" light from an object is less than the reflection intensity of "cool white" light, the surface areas with a greater distance to the luminaire insert also appear approximately the same brightness or at least as bright as the areas illuminated with "warm white" light , By choosing different colors in terms of red, blue, green, etc., also different color effects can be achieved. The different surface areas of the surface to be illuminated may also be spaced apart so that "dark" intermediate areas are created. Also, these areas can seamlessly connect or partially overlap.

To be able to adjust different lighting effects in a simple manner, it can be provided according to claim 6, that the groups of LEDs in their luminosity and / or color are controllable in groups and that by appropriate control of the groups of LEDs, the different areas of the surface to be illuminated are evenly or differently illuminated.

In order to apply a uniform or consciously illuminating surface with different luminous intensities with corresponding luminous fluxes to a surface to be illuminated, it can be provided according to claim 7, that the reflector is formed in several parts with its reflection regions and that the reflection regions of the reflector relative to each other and / or relative to the Groups of light emitting diodes are adjustable.

Further, it can be provided according to claim 8, that the adjustment of the illuminant carrier and / or the reflector regions is carried out by a respective motor drive. This configuration, in particular the setting of different lighting effects is considerably simplified and can be done in particular in finished luminaire insert in a luminaire housing.

According to claim 9, furthermore, a receiving device, to which control signals can be fed by a transmitting device, may be provided, wherein the receiving device effects the luminous intensity and / or color of the groups of light emitting diodes and / or the adjustment of the motor drives in dependence on the incoming control signals. As a result of this embodiment, the luminaire insert, in particular with regard to its illumination effect, can be variably adapted to desired lighting effects in an extremely simple manner. In particular, with changing requirements, these effects can also be adjusted variably.

Furthermore, it can be provided according to claim 10 that the luminaire housing receives the luminaire insert with its groups of light emitting diodes and its reflector and forms a light exit window and that the groups of light emitting diodes are arranged in a first edge region of the light exit window and that the reflector in a second, the first Edge region is preferably arranged opposite edge region of the light exit window and that the reflector with its reflection regions has a concave curved, the light emitted from the light emitting diode surface bundling surface.

For this purpose, furthermore, for a correspondingly desired bundling of the individual luminous fluxes according to claim 11 it can be provided that the radii of curvature of the reflection regions of the reflector are different and that the radius of curvature of the reflector region through which the luminous flux of the one group of light-emitting diodes into a region of the surface with less Distance is reflected to the luminaire insert is smaller than the radius of curvature of a reflection region through which the luminous flux of another group of light-emitting diodes is reflected in a region of the surface at a greater distance from the luminaire insert. This embodiment is particularly advantageous for a uniform possible illumination of a surface to be illuminated large height.

Further, it can be provided according to claim 12, that in the edge region of the group vn LEDs a light emission window in the area of the group of LEDs covering aperture is provided and that the aperture is preferably formed adjustable. Through this aperture provided a direct light emission of the light fluxes of the groups of light-emitting diodes through the Light emission window of the luminaire housing avoided. At least a light emission is limited so far that the viewer is not dazzled by the light-emitting diodes arranged in the luminaire housing. Depending on the application may be preferably provided that this aperture is adjustable, so that the shading of the groups of light emitting diodes can be adapted to the given lighting task.

The invention will be explained in more detail using the example of a floor lamp. Instead of a floor lamp may also be a lamp, which is freely deployable, on one of the surface to be illuminated adjacent wall or a ceiling mountable.

In the 1 exemplified floor lamp 1 has a luminaire housing 2 on which a mounting frame 3 is attached. This floor lamp 1 is with its luminaire housing 2 sunk in a subsoil can be arranged, in this state, a circumferential mounting plate 4 of the mounting frame 3 rests on the ground. It is off 1 it can be seen that the luminaire housing 2 together with the mounting frame 3 on the upper side a kind of light exit window 5 forms.

The luminaire housing 2 used in the illustrated embodiment for receiving a light insert 6 which is inside the luminaire housing 2 and in particular "below" the mounting frame 3 is arranged. Thus, the light emission window 5 Upper side with a glass plate (not shown in the drawing) to protect the luminaire insert 6 be used. It can also be seen that the luminaire insert 6 at least approximately over the entire length of the lamp housing 2 extends and one below the rear edge region 7 of the light emission window 5 arranged light source carrier 8th having. This illuminant carrier 8th Opposite is a reflector 9 provided, which in the illustrated embodiment in the edge region 7 opposite edge area 10 of the light emission window 5 is arranged. This reflector 9 also extends approximately over the entire length of the lamp housing 2 and is with its top edge 11 below the edge area 10 of the light emission window 5 arranged.

2 shows a perspective section II-II 1 , Out 2 it can be seen that the mounting frame 3 over revolving, vertically downward mounting legs 15 fixed with the side walls 16 of the mounting housing 2 communicates. To accommodate a too in 2 not shown glass plate form these side walls 16 at least in the edge areas 7 and 10 of the light emission window 5 horizontally inward holding webs 17 and 18 , which along their inner edge with vertically upwardly directed support webs 19 and 20 are provided. The illuminant carrier 8th is in particular below the "rear" retaining bar 17 arranged and takes two lines in groups 25 and 26 arranged light-emitting diodes. In the illustrated embodiment, the light source carrier 8th designed such that the line by line superimposed groups 25 and 26 of light-emitting diodes together on this illuminant carrier 8th Find a place.

Next is out 2 recognizable that the reflector 9 with its top edge 11 below the light emission window 5 and approximately in the area of the height of the "front" retaining bar 18 is arranged. Starting from its top edge 11 extends the reflector 9 arcuate to approximately vertical below the two groups 25 and 26 of light emitting diodes. Accordingly, this reflector ends 9 with its "inner" end edge 27 on a roughly horizontal support plate 28 of the luminaire insert 6 , From this baffle 28 leads at a distance to the end edge 27 of the reflector 9 a vertically upwardly bent support plate 29 to the illuminant carrier 8th , which in the illustrated embodiment integral part of this support plate 29 is. It can also be seen that the illuminant carrier 8th in the direction of the arrow 30 bent by about 30 ° inwards on the support plate 29 is formed. The luminaire insert 6 is in the rear end by a connecting wall 31 partially closed, at which the reflector 9 fixed fixed. In the front area, like this 1 is apparent, is accordingly a second connecting wall 32 provided with which the reflector 9 also fixed in connection. Between the side wall 16 and the reflector 9 forms the luminaire housing 2 a recording room 33 which, for example, to accommodate utilities for the groups 25 and 26 the LEDs used.

3 shows the same section II-II 1 of the luminaire insert 6 without the luminaire housing 2 and without the mounting frame 3 , It can be seen that the lower baffle 28 in the illustrated embodiment in approximately horizontal, lateral extension two (or more) mounting sections 34 and 35 forms, which for fixed mounting of terminals 36 and a control device 37 serve, wherein the control device as an integral part of a power supply for powering the groups 25 and 26 of light-emitting diodes may have.

Next is out 3 seen that the rear connecting wall 31 the reflector 9 on the one hand stationary with the lower support plate 28 and on the other hand with the vertically oriented support plate 29 of the luminaire insert 6 combines. Thus this luminaire insert forms 6 a complete intrinsically stable unit, which is used in appropriately designed luminaire housing, as exemplified for the luminaire housing 2 the floor lamp 1 out 1 is shown. It is understood that this luminaire insert 6 in the illustrated configuration not just in a floor lamp 1 but also in different, for example, be integrated into a wall or can be integrated into a ceiling lamp housing is used. This is ultimately dependent on the intended use or the conditions of use for corresponding lighting tasks. Furthermore, in 3 the corresponding reference numerals 2 entered so that the description too 2 also on the presentation of the 3 to read, as far as the same components are shown there.

4 shows a sectional view of the floor lamp 1 with its luminaire housing 2 , It can be seen that the luminaire housing 2 box-shaped and between its side walls 16 the luminaire insert 6 receives. This is in the present embodiment with its support plate 28 with a bottom plate 38 of the luminaire housing 2 via a screw connection 39 connected. Preferably, several such screw connections are for this connection 39 provided, which evenly over the entire length of the lamp insert 6 are arranged distributed. Next is out 4 it can be seen that the terminals 36 and the control device 37 in the recording room 33 of the luminaire housing 2 next to the reflector 9 is included. On the retaining bars 17 and 18 is a circumferential sealing element 40 placed on the inside by the vertically upwardly directed support webs 19 and 20 is fixed.

On these supporting bridges 19 . 20 is a glass plate 41 attached, which against the luminaire housing 2 through the sealing element 40 is sealed. To hold the glass plate 41 is on the right side of the lamp housing 2 a fixed mounting plate 42 provided, which in the region of its upper end edge inward to the glass plate 41 directed mounting flange 43 forms. The glass plate 41 engages under mounting this mounting flange 43 and will be on the opposite side of the light emission window 5 through an angle sheet 44 kept stationary. This angle sheet 44 is via a screw connection 45 removable on the luminaire housing 2 held. This screw connection 45 has a fixed at the "rear" holding web 17 upwardly projecting threaded bushing 46 on. Overall, in the illustrated embodiment, two such screw connections 45 provided, of which in 1 both threaded bushes 46 in 1 are recognizable. Furthermore, it is off 4 seen that the mounting frame 3 with its mounting plate 4 the luminaire housing 2 surmounted laterally so that the luminaire housing 2 over this mounting plate 4 on a in 4 subsoil, not shown, supported vertically in the installed state.

Next is out 4 it can be seen that the luminaire insert 6 completely inside the luminaire housing 2 is arranged and the two groups 25 and 26 of LEDs below the left support bar 17 and thus below the light emission window 5 are located. Also, the angle α is about 30 ° in the direction of the arrow 30 inwardly bent lamp carrier 8th recognizable. This is an integral part of the vertically extending support plate 29 and has one predetermined distance to the oppositely disposed reflector 9 on. Because the two groups 25 and 26 of light-emitting diodes are arranged one above the other at a vertical distance, is also that of these two groups of light-emitting diodes 25 and 26 emitted luminous flux in different angles of radiation on the reflector 9 broadcast.

The reflector 9 is integrally formed in the illustrated embodiment and has a concave, cylinder-segment-like shape. It can be provided that the radius of curvature of the individual regions of the reflector 9 is formed differently. In 4 is here for example for the reflection areas 50 and 51 of the reflector 9 in each case a radius R1 or R2 drawn, wherein the radius R1 is smaller than the radius R2. This is due to the reflection range 51 a stronger focus of, for example, the group of LEDs 25 emitted light through the light exit window 5 reached through. The focusing of the reflection area 50 is accordingly lower due to the larger radius of curvature R2, so that through the light exit window 5 passing luminous flux has a larger angle of radiation.

5 schematically shows a possible beam path of the two groups 25 and 26 light emitted by light emitting diodes. So will the group 25 of light-emitting diodes a "light cone" 55 at a beam angle β of about 47 ° in the upper third of the reflector 9 radiated. From the upper third of the reflector 9 becomes this light cone 55 through the in 5 only schematically illustrated light exit window 5 on a wall surface 56 Reflected back. At the in 5 schematically illustrated luminous flux from the reflector 9 reflected or reflected light rays in a focal point 57 together, which at a distance in front of the wall surface 56 lies. After this focal point 57 diverge the light rays of this luminous flux 58 and then hit a wall area 59 the wall surface 56 on. The by the reflection of the reflector 9 caused scattering angle β1 of the luminous flux 58 is after passing through the focal point 57 in the illustrated embodiment, relatively large, so that the area 59 has a relatively high height.

The one from the group 26 Luminous flux of the "light cone" emitted by LEDs 60 leaves the group 26 the LED at a cone angle δ of about 52 ° and strikes the reflector 9 at about the height of its lower two-thirds. From there, this light cone becomes 60 in turn focusing reflected, with its light rays also a focal point 61 penetrate, which also at a distance in front of the wall surface 56 lies. After passing through the focal point 61 leaves the luminous flux 62 this focal point 61 and hits in an upper, in 5 only partially recognizable wall area 63 on the wall surface 56 on.

How out 5 can be seen by way of example, are the two wall areas 59 and 63 vertically above each other and merge seamlessly into each other. With appropriate configuration, on the one hand, the distances of the groups 25 and 26 from the reflector 9 as well as the distances of these groups 25 and 26 of LEDs among themselves and also the direction of their light cone 55 and 60 Here can different wall areas of the wall surface 56 be illuminated.

Next is out 5 it can be seen that the emission angle δ1 of the luminous flux 62 is formed considerably smaller than the radiation angle β1 of the luminous flux 58 , This will result in a more intense illumination of the area 63 reached. As the area 63 considerably further away from the reflector 9 However, due to the smaller radiation angle δ1, approximately the same brightness in this range is obtained 63 reached.

From the schematic representation of 5 showing the beam path, starting from the two groups 25 and 26 of light-emitting diodes shows only schematically, it can be seen that a wall surface 56 above the lamp insert 6 is extremely evenly illuminated. By appropriate choice of orientation and arrangement of the groups 25 and 26 of light emitting diodes relative to the reflector 9 can the areas 59 and 63 vary. Also, instead of just two lines arranged in groups 25 and 26 of light-emitting diodes also be provided a plurality of groups of LEDs, so that several areas of the wall surface 56 can be illuminated. In particular, it can also be provided that the in 5 exemplified and adjoining areas 59 and 63 partially cover, so that extremely soft "transitions" are achievable.

Furthermore, the light intensities of the groups could 25 and 26 also be different from light emitting diodes. For example, the group 26 emit a "warm white" light from LEDs, which is less bright. As the distance of the area 59 to the reflector 9 is considerably smaller than the distance of the area 63 from the reflector 9 , results in spite of the lower luminosity of "warm white" LEDs sufficient illumination of the area 59 ,

In contrast, if one uses for the group 25 of light-emitting diodes "cold white" LEDs, one obtains a higher energy yield, since such "cold white" LEDs cause a stronger luminous flux. The combination of this brighter light flux of the group 25 of light-emitting diodes in cooperation with the smaller scattering angle δ1 of the luminous flux 62 causes in the area 63 a similarly bright illumination with "cold white" light, as in the area 59 on which the "warm white" light hits. Since, in particular, "cool white" light is more strongly reflected by a surface to be illuminated, the observer thus has the impression of a relatively uniform illumination of the entire wall surface 56 in the two wall areas 59 and 63 , Next is out 5 it can be seen that the luminaire insert 6 with its light exit window 5 with a relatively small distance to the wall surface 56 is arranged. This distance can be only a few centimeters. Despite this for lighting relatively unfavorable relative position of the lamp insert 6 with its light exit window 5 to the wall surface 56 this is due to the special arrangement of groups 25 and 26 of light emitting diodes relative to the reflector 9 sufficiently evenly illuminated.

On the basis of this basic concept, however, it is also possible, in particular with regard to the position and orientation of the groups 25 and 26 the LEDs relative to each other and relative to the reflector 9 to achieve different lighting effects. For example, the groups of light emitting diodes 25 and 26 be equipped with "color change light diodes" which by appropriate control - for example via the control device 37 - emit different color light streams. Also, the reflector can 9 be formed in several parts, the groups of light-emitting diodes 25 and 26 can be provided with different optical lens systems, so that the cone angle of their light cone 55 and 60 can also be more or less big.

In particular, these light cone 55 and 60 be designed with respect to their respective cone angle β or δ such that this only a predetermined reflection range of the reflector 9 apply a luminous flux. In this case, the luminous flux or light cone must 55 and 60 do not penetrate each other, as in 5 is shown by way of example.

Is such a reflector 9 designed in several parts, so its individual reflection areas can also against each other and relative to the groups 25 and 26 be individually adjustable by light emitting diodes. Preferably, a motor position can be provided here, which can also be controlled remotely.

Also the adjustment of the groups 25 and 26 Of LEDs or even further provided groups of light emitting diodes can be motorized and remotely controlled, so that after the installation of such a floor lamp 1 like these in 1 is shown by way of example, various lighting effects are adjustable in retrospect and remotely controlled.

To show the 6 to 9 exemplary and schematically several different settings, in particular the groups 25 and 26 of light emitting diodes.

From the schematic representation of 6 can be seen that in this illustrated embodiment, the support plate 28 is formed in two parts and one in the direction of the double arrow 65 adjustable bearing section 66 forms. At this storage section 66 is a vertically upwardly bent support plate 67 molded, which has a storage wall 68 with the storage section 66 communicates. This storage wall 68 is in the end areas, according to the connecting walls 31 and 32 like these in 1 are recognizable, on the storage section 66 and the support plate 67 provided twice. Between these storage walls 68 become two light sources 70 and 71 recorded on which the two groups 25 and 26 of light emitting diodes are arranged.

Due to the adjustability of the bearing section 66 is thus the distance of the groups 25 and 26 to the reflector 9 adjustable within certain limits. By this adjustability thus meet depending on the distance of the groups 25 and 26 the LEDs from the reflector 9 the luminous flux according to the arrows 72 and 73 respectively. 74 and 75 in different areas on the reflector 9 on. Due to the curved course of the reflector 9 are thus different emission directions from the reflector 9 adjustable, as indicated by the arrows 76 . 77 . 78 and 79 is shown schematically.

This shows 7 another adjustment of the two groups 25 and 26 of light emitting diodes. How out 7 it can be seen, are the two light sources 70 and 71 in the warehouse wall 68 in vertical slots 80 respectively. 81 added. Accordingly, the two illuminant carriers 70 and 71 in the direction of the double arrow 82 vertically relative to each other and relative to the reflector 9 adjustable. According to this adjustment, the same effect can be achieved as already 6 described. Accordingly, the main beam directions through the corresponding arrows 72 to 75 , starting from the groups 25 and 26 of light emitting diodes, in 7 shown. Since here too the impact areas on the reflector 9 depending on the vertical position of the groups 25 . 26 change from light emitting diodes, is also accordingly the emission direction of the reflector 9 adjustable, like this in 7 also by the arrows 76 to 79 is indicated. Preferably, the embodiment according to 6 with the embodiment according to 7 be combined so that the radiation directions from the reflector 9 are variably adjustable in a relatively large area.

In addition to the sliding adjustment in the direction of the double arrow 65 or the double arrow 82 can also be a swiveling storage of the groups 25 and 26 of light-emitting diodes or their illuminant carrier 70 and 71 be provided as example 8th is removable. The corresponding main beam directions are also indicated by the arrows 72 to 75 shown schematically. According to the impact area on the reflector 9 Thus result also by such a pivotable storage or pivotal adjustment of the groups 25 and 26 of light emitting diodes different Hauptabstrahlrichtungen, as shown in 8th through the arrows 76 to 79 is indicated schematically.

Furthermore, above the groups 25 and 26 of LEDs a plate-shaped aperture 85 be provided, as in 9 is shown. This can be in the direction of the double arrow s 65 be designed adjustable. By this measure, the groups of light-emitting diodes 25 and 26 Be covered "glare-free", so that in particular an adaptation to the prevailing conditions of use is possible and the in 1 Floor lamp shown can be used glare-free.
