Description

The present invention relates to an optical unit for a lamp and a lamp with at least one such optical unit.

For illuminating rooms and objects usually bulbs are used, which generate light during operation. Such lighting means may be accommodated in an optical unit which provides a housing or a frame part and / or a receptacle for the lighting means. It is also conceivable to equip such an optical unit with a reflector in order to reflect the light generated by the light source. The problem with such optical units is in particular an uneven illumination of a larger area or a larger space and / or that the reflectors can lead to dazzle of people located in the vicinity of the optical unit people.

The present invention is therefore concerned with the task of providing for an optical unit of the type mentioned and for a luminaire with at least one such optical unit an improved or at least other embodiments, in particular by a large and / or uniform and / or glare-free lighting and / or simply manufacture.

The present invention is based on the general idea to provide an optical unit for a luminaire with at least two rows of optics, the each have adjacent optical lenses, wherein the lenses each redirect the light generated by an associated light source and / or break, so that let the light generated by the light bulbs selectively exit from the optical unit. Thus, it is possible to evenly illuminate a larger area or a larger room with the optical unit. In addition, the illumination by means of the optical unit can in particular be glare-free, that is to say without diaphragms of persons located in the surroundings or at least with a reduced aperture of the persons.

According to the idea of the invention, the optical unit for a luminaire has a plurality of straight rows of optics each having a plurality of lenses adjacent in the longitudinal direction of the optical unit and arranged side by side in a transverse direction of the optical unit. Furthermore, a frame is provided, which extends from an upper side of the optical unit in a height direction of the optical unit to a lower side of the optical unit and which encloses the lenses of the optical rows closed in a circumferential direction, wherein the lenses and the frame in an integrally manufactured, rectangular, plate-shaped and transparent plastic body are integrally formed. The height direction, the longitudinal direction and the transverse direction are perpendicular to each other. The direction of rotation runs around the height direction. The plastic block is rectangular in a plane extending in the longitudinal direction and in the transverse direction. The integral design leads to very close tolerances of the individual lenses to each other, whereby a uniform light emission can be realized.

Preferably, the frame may have a heightwise extending outer frame wall which revolves in the direction of rotation. This results in a high-quality lateral conclusion for the optical unit.

Optionally, it can be provided that the lenses of at least two of the optical rows are aligned with one another in a transverse direction running transversely to the longitudinal direction and transversely to the vertical direction. This results in a geometrically simple, symmetrical structure, on the one hand relatively inexpensive to produce and on the other hand favors the desired homogeneous radiation performance.

Furthermore, it can be provided that the plastic body has at least one strut arranged between two such rows of optics and projecting in the height direction in the direction of the upper side. This strut can be used to attach the plastic body and thus the entire optical unit to other components.

The support frame may preferably be a metal component and, for example, consist of a light metal or of a light metal alloy. In particular, this may be a profile body. This preferably metallic support frame can be used to stiffen the plastic body. In addition, other functions of the lamp can be realized on this support frame. At the same time, the high-quality optics of the optical unit can be maintained because the support frame is recessed in the optical unit. Namely, at their back facing away from the viewer, so at the top.

A refinement is characterized in that the plastic body has a plurality of struts arranged between two such rows of optics and projecting in the height direction in the direction of the upper side, which struts are spaced apart in the longitudinal direction. Furthermore, it can be provided that the support frame for each of these struts has a passage opening through which the respective strut passes in the height direction. As a result, the respective strut for attaching the optical unit can be used on the support frame.

Particularly advantageous is an embodiment in which it is provided that the respective strut has on a side remote from the lenses of the support frame by plastic deformation compared to the rest of the strut in the transverse direction widened head, which is no longer pulled out in the height direction through the passage opening , This simplifies the manufacture of the lamp.

Suitably, the LED lighting means may be attached to at least one board, which is clamped within the plastic body between the support frame and the optical rows in the height direction. In other words, the respective board is fixed by clamping, which simplifies the assembly.

In addition, an electronic control system can be provided which serves for electrical control of the lamps and which is arranged on the support frame. This also simplifies the assembly of the respective lamp.

With the Linear module is therefore linearized over the light exit of the lens emerging light and thus can be emitted more uniformly or evenly. Preferred are embodiments in which the optical unit is designed such that the light generated by the bulbs emerges 70% over the bottom and 30% over the top. Thus, a particularly homogeneous, uniform illumination is achieved. The light emitted downwards creates a direct illumination. The light emitted upwards ensures indirect lighting. Appropriately, separate light sources are provided for generating the direct and indirect lighting, which can be controlled separately.

A control electronics of an associated luminaire controlling at least one such luminous means is preferably arranged within the frame. Thus, the lamp can be particularly compact and / or requires no external electrical control, but only an electrical supply to be operated. This considerably simplifies the use of the optical unit, in particular in the associated lamp.

The lenses of the respective optical series can be arranged arbitrarily relative to one another. It is conceivable to arrange the lenses of two of the optical rows offset relative to each other. Also conceivable are embodiments in which the lenses of at least two of the optical rows are aligned with one another in a transverse direction running transversely to the longitudinal direction and transversely to the vertical direction.

As explained above, the optical unit has at least two such rows of optics. Embodiments in which the optical unit has at least three, in particular four, rows of optics are preferred. This allows in particular a more uniform illumination and / or sufficient Illumination of a surface to be illuminated or of a room to be illuminated.

The plastic body can in principle be made of any transparent plastic. Preferred are variants in which the frame part is made of a hard plastic. This leads in particular to a stabilization of the optical unit. The plastic body can be made of polymethylmethacrylate (PMMA), in particular of acrylic glass.

The frame may have at least one extending in the vertical direction, outer frame wall which laterally surrounds the lenses and so forms a lateral termination of the optical unit. In this case, it is preferable for the at least one frame wall to run circumferentially, in particular closed circumferentially, and thus surround the interior of the plastic body circumferentially, in particular closed circumferentially.

In preferred embodiments, the frame and the lenses of the optical unit are integrally formed, in particular of the same material. That is, the frame and lenses are made of plastic, especially PMMA. In particular, it is conceivable to manufacture the frame and the lenses together by a casting process.

The optical unit is, as mentioned above, used in a lamp. Accordingly, a luminaire incorporating such an optical unit is also within the scope of this invention. The luminaire may in particular have two such optical units. In this case, the lamp next to the light unit and at least one light source, preferably an LED bulb. An LED illuminant is characterized by a large number of parallel controllable LEDs. However, the respective lighting means can in principle be designed as desired. It is conceivable that at least two different lamps are used. In this case, the respective lighting means may in particular be a light-emitting diode (LED), a light bulb and the like.

Variants in which the luminaire has a supporting frame, in particular a metal profile, which is arranged in the frame of the optical unit prove to be advantageous.

An optical unit 1, as in FIG. 1 is shown has a plurality of lenses 12 and a frame 2. Within the frame 2 are at least two rows of optics 3, wherein the example shown has four such optical rows 3. The optical rows 3 are rectilinear and arranged parallel to each other, so that they each extend in a longitudinal direction 4 of the optical unit 1 and are adjacent to each other in a transverse to the longitudinal direction 4 transverse direction 5 of the optical unit 1. The optical unit 1 has an underside 6, which in FIG. 1 facing the viewer. The underside 6 opposite and spaced in a transversely to the longitudinal direction 4 and transverse to the transverse direction 5 extending height direction 7, the optical unit 1 has a top 8, the in FIG. 1 turned away from the viewer.

In FIG. 2 is a longitudinal section through a lamp 9 to see that has two such optical units 1. In FIG. 3 is a first cross section through the light 9 and in FIG. 4 to see a second cross section through the light 9. In FIG. 5 is an isometric view of an underside 10 of the lamp 9 to see, which is defined solely by the bottom 6 of the optical unit 1, while in FIG. 5 an isometric view of an upper side 11 of the lamp 9 can be seen, which faces the upper side 8 of the optical unit 1.

The respective optical series 3 of the optical unit 1 has a multiplicity of lenses 12 which are adjacent in the longitudinal direction 4. Here, the runs in FIG. 3 shown cross section through such lenses 12, while the in FIG. 4 shown cross section between adjacent longitudinally 4 lenses 12 extends. The particular lens 12 is, as can be seen in particular in FIG configured as a solid body and configured so that it can radiate towards the bottom 6, 10 down. From an associated light source 42 (see FIG. 4 ) generated light may exit at the bottom 6 and 10 from the optical unit 1 and from the lamp 9. The respective lens 12 may be hemispherical in shape and may have a light inlet 13 on the side facing the upper side 8, 11. This light inlet 13 has an unspecified, annular Collar, and a unspecified well, which is bordered by the collar. Within the recess, the lamp 12 associated with the respective lens 12 is arranged. Thus, at the respective light inlet 13, a lamp 12 belonging to the lens 12 is provided such that the light generated by the light source 42 radiates through the light inlet 13 into the lens 12. The optical unit 3 has on the underside 6 a light exit section 14 for emitting light of the respective luminous means 42. In the example shown, the respective lens 12 or the respective luminous means 42 is assigned such a light exit section 14, which in the example is formed by a flat radiating surface 15. In other examples, the light exit section 14 may include a diffuser or the like. On the side facing away from the bottom 6, 10 side of the lenses 12 and the light exit openings 13 adjacent to a light panel 41, in particular a light board 43 or short board 43, arranged, which has the lighting means 42. In the example shown, the lighting means 42 are each a light-emitting diode (LED) 44, wherein the light-emitting plate 43 carries the LEDs 44. The light-emitting means 42 may also be referred to below as LED light-emitting means 42.

In the example, only bulbs 42 are shown, which emit downward and provide direct illumination. Optionally, further lighting means may be provided, which are not shown here, which emit upward and provide indirect lighting. These further bulbs may e.g. Be arranged on a side facing away from the lenses 12 side of the support frame 20 outside the cover 19.

The lamp 9 has a control electronics 16 for the electrical control of the LED bulbs 42, which is arranged within the optical unit 1. Thus, the optical units 1 are simplified for the manufacture of the lamp 9 can be used.

The entire optical unit 1, so the lenses 12 and the frame 2 are made of transparent plastic and thus stable and weight-reduced. Furthermore, the optical unit 1 is formed by a single, uniform material produced plastic body 47 having the lenses 12 and the frame 2 as integral sections or areas.

As in particular from FIG. 1 shows, the lenses 12 of the optical series 3 are arranged evenly distributed. In this case, the lenses 12 of the optical rows 3 in the transverse direction 5 are aligned with one another. This results in a regular arrangement of the lenses 12 from mutually perpendicular and lying in a row rows and rows.

From the FIGS. 3 and 4 shows that the plastic part 47 has at least two struts 45 which project in the direction of the upper side 8. The struts 45 are arranged in the example between the transverse in the middle 5 and outer optical rows 3. In this case, the plastic part 47 has a plurality of such struts 45, which are spaced apart in the longitudinal direction 4, in particular arranged in a row, are. By a thermal process, the struts 45 can be plastically deformed at their free ends, to produce a respective head, which is dimensioned larger in the transverse direction 5 than the rest of the strut 45th

In particular from the FIGS. 1 . 3 and 5 also shows that the frame 2 has at least one running in the height direction 7 outer frame wall 46. The at least one frame wall 46 surrounds the inner of the optical unit 1 and is preferably formed circumferentially closed.

In the example shown, the optical units 1 are arranged adjacent to one another in the longitudinal direction 4, wherein the intermediate piece 17 is arranged between the optical units 1. In this case, the intermediate piece 17 is connected to the mutually facing longitudinal ends of the optical units 1, such that the optical units 1 are thus connected to each other. In the example shown, a sensor 18 is integrated or arranged in the intermediate piece 17. With the sensor 18, it is possible, in particular, to control the lighting means of at least one of the optical units 1, in particular to activate and / or deactivate them when, for example, a person enters the surroundings of the light 9.

In FIG. 7 is a plan view of the lamp 9 to see, with an in Fig. 6 shown cover 19 of the lamp 9 on the upper side 11 is not shown. It can be seen that the lamp 9 has a support frame 20, which is arranged recessed in the optical units 1. The support frame 20 is a metal component, in particular a metal profile. The support frame 20 is inserted through the top 8 of the optical units 1 in this. The support frame 20 bears against the at least one frame wall 46 of the frame 2. The support frame 20 has a plurality of passage openings 21 aufm, which are designed here as slots. About these passage openings 21, the optical units 1 and the support frame 20 are fixed so that the support frame 20 carries the optical units 1. If the intermediate piece 17 is present, this can in principle be attached to the support frame 20 in a similar manner. Preferably, the struts 45 of the respective optical unit 1 are respectively inserted into such a passage opening 21 of the support frame 20 and fixed in a form-fitting manner by the above-mentioned head. In other words, during assembly, the struts 45 are inserted into the passage openings 21 and then on a side facing away from the lenses 12 of the Support frame 20 plastically deformed, for example under the influence of heat, to produce said head, which can no longer pull back through the passage opening 21.

The in the FIGS. 2 to 7 shown light 9 is designed as a pendant lamp 22, which by means of a in Fig. 3 indicated with broken line suspension 48, such as a rope, a chain or the like, can be attached to a ceiling, not shown. For this purpose, the luminaire 9 has at least one fastening element 23 on the upper side 11. The fastening element 23 is formed by a Kedernut which is integrally formed on the support frame 20.

The suspension 48 may then be firmly connected to a Kederstein 49, which is inserted axially, ie in the longitudinal direction 4 in the Kedernut 23.

In addition, in the example shown, the optical units 1 have an optical unit length 24 running in the longitudinal direction 4 which is greater than an intermediate piece length 25 of the intermediate piece 17 extending in the longitudinal direction 4. The optical units 1 are of identical construction and therefore have in particular the same optical unit length 24.

Another embodiment of the lamp 9, in particular the pendant lamp 22 is in the FIGS. 8 and 9 shown. This embodiment differs from that in the FIGS. 2 to 7 shown embodiment in particular in that in the intermediate piece 17, no such sensor 18 is provided or arranged thereon. In addition, the intermediate piece 17 has a Adapter length 25, which corresponds approximately to the optical unit length 24 of the respective optical unit 1.

In this embodiment, the lamp 9 also has two such optical units 1. In contrast to the examples shown so far, however, the optical units 1 are not arranged adjacent in the longitudinal direction 4, but in the transverse direction 5. In addition, the lamp 9 has a housing 27, in which the optical units 1 are accommodated, wherein the housing 27 on the underside 10 of the lamp 9 each have a recess 28 for the respective optical unit 1, so that the light generated by the lamps on the Lenses 12 and the recesses 28 can emerge from the light 9 or light. In this embodiment, the
Light exit openings 13 of the lenses 12 omitted. The ceiling light 26 has at the top 11 not visible fasteners for attaching the ceiling light 26 on a ceiling, not shown. The optical units 1 are attached to this housing 27 via separate support frames 20. The fasteners may be suitably formed again on the support frame 20 to hang the lamp together with the housing 27.

Another embodiment of the lamp 9 is in the FIGS. 13 and 14 shown. In this embodiment, the lamp 9 is formed as a floor lamp 29. In this case, the lamp 9 has two such optical units 1, which are arranged adjacent in the transverse direction 5 and connected to each other via such an intermediate piece 17.

The modular system 35 may also include different types 39, 40 of such optical modules 36 or optical units 1 that differ. In the example shown, a first type 39 of optical modules 36 has a smaller optical unit length 24 than a second type 40 of the optical modules 36. This makes it possible, in particular, to produce different lamps 9. For example, for manufacturing in the FIGS. 2 to 7 shown pendant lamp 22 optical modules 36 of the second type 40 are removed, while for the manufacture of the floor lamp 29 optical modules 36 of the first type 39 can be removed. Of course, it is also possible to use 9 different types 39, 40 of optical modules 36 and light units 1 for the same lamp. It is also possible for the modular system 35 to comprise further types of optical modules 36 or optical units 1, not shown.
