Description
Technical field
The present invention relates to a kind of luminaire of the preamble according to claim 1.
Background technology
Under the situation of such luminaire, this luminaire is that Known designs, particularly previously known are pendant-type luminaire.The key character of this luminaire is, it has first light emitting area on a side of its housing for the direct illumination in space, and be used for this space of indirect lighting and be arranged on luminaire with the first light emitting area opposed rear side on second light emitting area.The purpose of second light emitting area with influence of light element of printing opacity is, illuminate luminaire around sidepiece and/or the rear portion with reduce first light emitting area and luminaire on every side between light-intensity difference, and/or particularly in the indirect lighting of the rear portion of luminaire generation except direct illumination, this has improved the illumination in space and has reduced the rear portion of luminaire and the luminance difference of lateral region.This luminaire for example is described among EP 1 734 300 A1.
The element that the influence of light element of the printing opacity of second light emitting area for example can be printing opacity or local printing opacity and formed by transparent plate or porous chips, it for example is arranged in the zone of rear wall of housing of luminaire.
Previously described this luminaire is suspended on usually apart from the ceiling distance of 50cm at least.This suspension height guarantees to have in the ceiling side the not dazzling optical density of pleasant impression.Yet, under specific applicable cases, luminaire need be assembled under the short distance of distance ceiling or the situation at the high spatial of the great distance of distance ceiling, this can cause in the ceiling side on the one hand and form undesirable high luminous density, it can be unfavorable for the installation of this luminaire and restrict the operation possibility thus, perhaps can cause the luminous density that under the situation of big suspension height, forms in the ceiling side low excessively on the other hand, and the ratio of desirable indirect light become too little in the space.
Summary of the invention
Therefore, basic goal of the present invention is to improve the indirect lighting of this luminaire that begins to point out.Particularly, the light of launching for indirect lighting just utilizes in better mode, is preferred for the lateral edge zone of luminaire.Thus, under the situation of the room of correspondence height, namely, have low suspension height and be close to the ceiling below, just, in so-called putting (built-on) or surperficial installation site, or have under the situation of big suspension height, luminaire will all can be mounted, and guarantees optimal light distribution relevant with direct light and that be correlated with indirect light simultaneously.
This purpose realizes by the characteristic of claim 1.The other favourable improvement of the present invention is described in the relevant dependent claims.
Main sign of the present invention is, because the deficiency of indirect lighting causes the particularly luminance difference in the fringe region of luminaire substantially, so indirect lighting is particularly very important in the lateral edge zone of luminaire.
Under the situation according to luminaire of the present invention, the second influence of light element relevant with second emitting area can be adjusted at least two diverse locations.Therefore, can make the second influence of light element adapt to specific influence or arrange and can not influence the light of indirect lighting.Can be for example at luminaire or the light that carries the ceiling side of profile accordingly and provide rotation to install and/or removably install distribute the wing as the second influence of light element, its form and/or size with and select apart from the respective distance of ceiling according to luminaire 1 especially with respect to position and the energy that tilts of the vertical central plane of luminaire.The second influence of light element thus can be for example regulated in the mode of the opening that can be used for limiting the light that is suitable for indirect lighting, thereby limits littler or bigger opening according to the position, or makes opening unlimited fully.
Particularly, when the second influence of light element was reflector, indirectly luminous energy was reflected and deflects to sidepiece, thus be used for luminaire edge area add strong illumination.In this case, except existing reflecting surface, in the luminaire side other reflecting surface is set if applicable, and anti-glare surface is set if applicable, thereby obtain the specific possibility that is suitable at different room height or suspension height.
At low spatial and can be under the situation of the corresponding short suspension height that adjacent superset is put, light distributes the wing for example to be configured and to form size in the following manner: avoid the unacceptable high luminous density at the ceiling place, and realize illuminating and the generation of direct light thus of the big zone of ceiling.On the other hand, under the situation of very large suspension height, wherein the luminous density at ceiling place becomes too low and produces insufficient indirect light, it is to have bigger surface that light distributes wing preferable configuration, and be used for to desirable, the soft indirect light of spatial emission, this indirect light in this case can not be by being passed to abundant scope in the ceiling reflection way.
Because the light as the second influence of light element distributes the wing can be formed reflection, transparent and/or partially transparent, consider wing formula and the wing size freely selected greatly, can realize that the very different light between direct light and the indirect light distributes according to the corresponding scope of application of luminaire.
Other advantageous embodiment of the present invention is that not only the second influence of light element forms and can be rotated, particularly can be rocked to stand, the euphotic cover that also is to be arranged in the fluorescent lamp top that is arranged on the luminaire housing is constructed in a similar fashion and is made the swing or rotate of self make progress in the corresponding way, and if possible need to change, lamp is easier to be approached.
The second influence of light element preferably rotates installation, particularly is installed on the covering profile that links to each other with the reinforcing profile of opening in the ceiling side or hollow carrying profile by kayser bindiny mechanism.Be used for the use of the covering profile of the installation second influence of light element, cause on the one hand technical and in essence very simply solution can be modified, the stand (it is invalid in the light technological invention) that allows the second influence of light element to leave covering profile top by simple rotary course is transferred to POF on the other hand, at this POF, because reflection and/or diffuse effect, this second influence of light element will be distributed on the big surface on the ceiling from the light of the light source that is arranged in luminaire or from the light of corresponding reflecting surface.Under the situation of this embodiment, the second influence of light element preferably is constructed to have less surface, and just, its surface is equivalent to substantially at the carrying profile side reflecting surface adjacent with this second influence of light element, and is not limited to the size ratio of this reflecting surface.
On the other hand, situation for the big suspension height in corresponding high room or space, the second influence of light element preferably has the spill exterior domain on big surface, it is as replenishing the associated reflections surface that reinforces profile or hollow carrying profile, not only help to produce direct light, also be used for providing the ratio of desirable indirect light, indirect light can not provide by the diffuse effect at ceiling place owing to bigger suspension height in this case.
Other advantageous embodiment is feature with the following fact further: cover profile and have the groove that part is columniform, upwards open at edge side in all cases, this groove has the bar of cylindrical profile, and this bar links to each other with trench bottom with one heart and by web about groove; The support-side edge of the second influence of light element forms the columniform Connection Element of part; And at engagement state, have with the concentric profile bar of groove and in the mode that forms locking and be bonded on the columniform groove of part of the Connection Element in the housing region between groove and the profile bar, form rotate hinged.
Being opened on of the columniform groove of part is to cooperate in the following manner with the cylindrical Connection Element of the part of the second influence of light element: the second influence of light element perpendicular to the longitudinal extent of holding tank can insert this groove, and, because the second influence of light element is swung away from the insertion position, actual hinged formation realizes automatically.The second influence of light element becomes possibility with covering separating correspondingly between the profile in corresponding simple mode, and reason is that the influence of light element only needs rotation to return above-mentioned insertion position for this purpose, can separate with the covering profile then.
This easy connection of the second influence of light element also is preferred version in conjunction with the further special characteristic of the present invention with separating, namely the influence of light element can be inserted the holding tank that covers profile so that it is offset 180 ° possibility, reason is to adopt such assembling, the influence of light element can be outside, folding downwards, for example is supported on then on the euphotic cover that is suitable for light source on top.The result of this situation is, the part selected of this printing opacity light cover has dazzling inhibitory action upwards, and the light that passes this part of lid reflects downwards by the second influence of light element, thereby strengthens direct light.So the luminous sealing that can guarantee the ceiling place directly over the lamp always keeps within the acceptable range.
The further advantage of the present invention that need mention especially is the following fact equally: preferably be made of Heat Conduction Material and the second influence of light element that links to each other with heat-conducting mode and hollow carrying profile all forms effective cooling surface in its all operations position.
Improvement according to the present invention is suitable for all such luminaires: its lateral edges from the ceiling of its supporting body, particularly room with respect to the emitting side of the luminaire distance along laterally steering.Therefore the present invention very advantageously is applicable to pendant-type luminaire.Yet the present invention also is applicable to the overhead luminaire, particularly when the rear wall of luminaire tilts towards lateral edges.
In addition, above-mentioned purpose also realizes by the characteristic of independent claims 27.Under this improved situation according to the present invention, housing is flat shell, and second emitting area is arranged on the rear side of flat shell, and snap action bindiny mechanism is arranged in the zone of inward flange of second emitting area.This improvement according to the present invention causes in the luminaire of flat structure, and indirect lighting is because lower structure height and comparison difficulty.Yet, even provide this illuminator structure, still can improve indirect lighting according to improvement of the present invention, particularly the indirect lighting in the zone, opposite side edge of luminaire.In addition, under the situation of this luminaire, the second influence of light element assembly and disassembly easily, therefore luminaire optionally is suitable for indirect lighting.
Provide a kind of luminaire according to the 3rd independent claims 28 at last, particularly have room lighting device or the pendant-type luminaire of flat structure, it has the light emission surface that is positioned on room and/or the ceiling side; Hollow carrying profile, it is arranged on the center and between two end parts, and has high-caliber transverse bending strength, and being used for the interior spatial accommodation of at least two fluorescent lamps and outer spill reflecting surface, to be adjacent to extend to hollow carrying profile also in parallel; Being arranged on hollow carries on the both sides of profile and the photoconduction chamber of the sidepiece of fluorescent lamp, extend in this photoconduction chamber makes it reduce to the horizontal boundary of luminaire gradually, and on room side, sealed by light emission surface at least, wherein, the influence of light element distributes wing formula to be arranged on the ceiling side with light, its rotation is installed and/or is removably mounted on the hollow carrying profile, and its form and/or size with and with respect to the position of the vertical central plane of hollow carrying profile and/or tilt and can select apart from the respective distance of ceiling according to luminaire especially.

With first emitting area, 4 opposed rear side, luminaire 1 has at least one second light emitting area 21 that is suitable for indirect lighting, it is formed by the printing opacity of rear wall 2c or the part of part printing opacity, and, preferably exist the second influence of light element 22 to cooperate with this second light emitting area 21 in the outside, this second influence of light element will further be described hereinafter in more detail, and the luminous energy that sends from second emitting area 21 second influence element influence or change, particularly lateral deflection by this.
Shown in the suspension of luminaire 1 preferably realize by the suspension arrangement that cooperates with cable and can be connected to the end of luminaire 1.Usually, luminaire 1 equals 50cm at least apart from the suspension height of ceiling, so that the indirect light of guiding ceiling can not produce height to having luminous density interfering and may be dazzling at ceiling.Yet this can not be applied to for example only equal the situation of the low suspension height of about 25cm, can not be applied in luminaire certainly and must directly be assembled in the situation that the superset of so-called ceiling below is put.
In order there to be the indirect light of guaranteeing to obtain desired ratio under short-range these situations between luminaire 1 and the ceiling; luminaire 1 according to the present invention is provided with influence of light element 22; even it also can distribute indirect light at luminaire 1 very in short-term widely apart from the distance of ceiling, and guarantee that the luminous density at ceiling place remains in the regulation zone.
Under the both sides of vertical central plane E2 were provided with situation for this exemplary embodiments of lamp 7 or two Connection Elements 6 arranging with this lamp, two second emitting areas 21 that have the second influence of light element 22 all arranged in the mirror-inverted mode about vertical centre axis E2 in each case.Therefore hereinafter, half that only limits to luminaire described, i.e. the left side of luminaire.
Second emitting area 21 in the emitting area of rear portion, be positioned at above the lamp 7 or jockey 6 above, in the zone of this jockey 6, be positioned with relevant lamp 7.Indirect lighting is improved by the following fact, that is, second emitting area 21 is set to make it to tilt towards relevant lateral edges.Angle W2 between rear wall 2c and the diapire 2a equals about 20 ° to 40 °, particularly about 30 °.
In this exemplary case of the embodiment, second emitting area 21 is formed by the covering wall 23 of printing opacity or part printing opacity, among this covering wall 23 sealing rear wall 2c with the shape corresponding opening 24 of this covering wall, particularly the fact that can be positioned in the opening 24 according to covering wall 23 is sealed, in this case, covering wall 23 forms the part of rear wall 2c.Opening 24 is enough big so that lamp 7 can move through this opening, and can link to each other with Connection Element or element 6, maybe can be removed or change.At least one Connection Element 6 forms in the following manner, namely, the lamp 7 that has a contact element its insertion with remove moving process in can cause during insertion relevant anti-contact element contacts with housing 2, and can disconnect with tactile the contacting in the removal process of element of this reversal connection.For example, if lamp 7 has at distolateral outstanding contact plug, the contact groove that then holds this contact plug is arranged on the case side, and guide along moving direction in the following manner, that is, contact plug can be filled in the groove in the insertion process of lamp 7, and can extract in demolishing process.
Covering wall 23 links to each other with housing 2 by joint 25, joint 25 in the zone at an edge of this covering wall, particularly at it in the zone at the edge of vertical central plane E2, this covering wall 23 is connected to the relevant edge zone of housing 2.Therefore, covering wall 23 not only is installed between its closed position and open position that causes lamp 7 assemblings or dismounting rotatably, and also remains on the housing 2 with non-removably.
For other influence of light, covering wall 23 for example can have the light induction element 26 of side within it, shines the light that passes through with influence.
The 21 preferred contiguous profile settings of reinforcing of second emitting area.The size b2's of half rear wall that the width b1 of second emitting area 21 equals to be correlated with is about 1/3rd to 1/5th, and particularly about 1/4th.Yet, it should be noted at this, also can extend second emitting area towards the sidepiece of luminaire.Therefore, for example, not only covering wall 23 transparent or printing opacity can be configured to be, and the luminaire housing its printing opacity at least in part can be configured to make in abutting connection with the rear wall of covering wall 23.
Joint 25 can preferably be assembled by its blank area of locking and dismantle by separating this blank area, just, and by assembling or dismantle along corresponding assembling or the dismounting campaign of transverse guidance with respect to the joint axis.
Covering wall 23 for example can by inwardly towards two supporting leg 23a, 23b that are positioned at the edge form in the U-shaped mode, wherein Xiang Guan blank area is arranged in the free edge zone of inwall supporting leg 23a.Therefore, joint 25 can be realized in its position that dents into housing 2.Wall supporting leg 23b on the outward flange for example stablizes by lug 27 in the closed position and improves covering wall 23, and this lug 27 cooperates with the edge of opening opposing 24 with locking or clamping mode in the depression closed position according to Fig. 2 and Fig. 3 right side.
Blank area is formed by the nip with two claw type groove supporting leg 25c, for example for the double pointed nail 25b of cylindrical cross-section can be latched between the described groove supporting leg, and goes out described groove supporting leg by elastic bending and separates.
Within the scope of the invention, joint 25 can form with the form that keeps tank by means of plug/rotation retainer without locking, this maintenance tank is opened and is caused covering wall 23 rotation possible in the insertion position towards the free edge of covering wall 23, and does not need the piston part of covering wall 23 on the covering wall sidepiece lockable therein.Realize automatically by the following fact closed position that be fastened on covering wall 23 of covering wall 23 in this maintenance tank: covering wall 23 fixes limit with this maintenance tank opposed edges by the opening 24 in the maintenance tank.
The second influence of light element 22 distributes wing one-tenth by the light of thin-walled portion form, and described light distributes the wing removably to link to each other with housing 2 by the snap action bindiny mechanism 31 in the zone of rear wall 2c.Under the situation of exemplary embodiment, snap action bindiny mechanism 31 is arranged in the zone of joint 25 or plug retainer, for example partly dents into the outer surface of rear wall 2c and/or estimates V to bias internal with skew.
The second influence of light element 22 can be conditioned, and strictness is rotated at least two different positions, and this realizes by the snap action bindiny mechanism 31 that is positioned at hollow carrying profile or reinforce on the profile 14.Two possible positions that are used for the second influence of light element 22 are represented by S1 and S2.At position S1, i.e. so-called smooth distribution locations, the second influence of light element 22 is laterally projecting with respect to rear wall 2c, namely projects upwards under the situation of overhead illumination device.On the other hand, at position S2 (Fig. 3), it is downward folding position, the second influence of light element 22 is positioned at the position of moving towards rear wall 2c, in this case, the second influence of light element 22 is preferred static against covering wall 23, and respectively completely or partially, or according to may situation almost completely covering covering wall 23 or opening 24.Under the situation of exemplary embodiment, the width b3 of influence of light element 22 is very big, so that its free edge ends at the outward flange distance c place before of second light emitting area 21 or opening 24.Distance c for example equals about 1/4 of b1.
At position S1, towards the wall surface 22a of relevant sidepiece preferably about being parallel to the curvature axis bending that median plane E2 extends, preferably with cylindrical cross-section bending or rounding.
The purpose of the second influence of light element 22 is to influence the light that sends from second emitting area 21, particularly at the light that sends in the zone of median plane E2 of second emitting area 21, and therefore changes indirect lighting.For this purpose, the second influence of light element 22 is printing opacity or formation reflector 32 at least in part, and this reflector will be emitted to the light of this reflector towards the sidepiece reflection away from median plane E2 by second emitting area 21.Reflector 32 for example can form like this: making towards the wall surface 23a of second emitting area 21 is emitting surface.Shown in the position, the second influence of light element 22 acutangulates W2 with median plane E2, they can be less than about 40 °.Therefore, at this light distribution locations S1 that produces, the wall surface place deflection that forms in the spill as reflection and/or diffusing surface from fluorescent lamp and the light that passes euphotic cover 23, and extensively be distributed in the scope of ceiling, so that when luminaire is assembled near ceiling, avoid producing at the ceiling place unacceptable high luminous density, and produce indirect light equably.
At position S2, the second influence of light element 22 is used for completely or partially, or according to may situation almost entirely covering opening 24 or second light emitting area 21, therefore at least in part light is covered.If second photocell 22 forms reflector 32 at this, the light in the institute overlay area is reflected so, so that in fact can not cause light loss in this zone.This second place S2 for example is used for preventing or reducing indirect lighting.When luminaire must be close to the ceiling below, namely when so-called superset is put assembling, can select this structure of the second influence of light element 22 so especially.In this downward folding position, influence of light element 22 is positioned at directly over the euphotic cover 23, or locatees in the mode of adjacency euphotic cover 23, thereby light is upwards blocked, and passes downward the reflection with the enhancing direct light of part of the light of influence of light element 22.Therefore the screen effect of having been passed through to be realized by influence of light element 22 outside, that fold downwards guarantees that the luminous density on the ceiling always remains on acceptable zone.
In addition, the second influence of light element 22 can preferably be adjusted to the 3rd position S3, and it inwardly and towards housing 2 moves in this position, and in this case, the second influence of light element 22 can be positioned at the upside of housing 2, and rests on rear wall 2c or the profile lid 15.At this position S3, the second influence of light element 22 is positioned at non-use position or stand, and this position is invalid according to the light technology, and for example can also be packing or transporting position.If two influence of light elements 22 are provided, these two can be overlapping and be laminated to each other, as depicted in figs. 1 and 2.
In addition, according to according to the present invention should improve and the situation of the position of influence of light element 22 under, importantly, influence of light element 22 is actually sightless, particularly at stand S3 and at the downward folding position S2 that leans on printing opacity covering wall 23, and, at these positions S2, S3, influence of light element 22 is positioned at the sight line inboard, and the observer in the space is draped or is installed in luminaire 1 on the ceiling side seeing below this sight line.Therefore, the outward appearance of luminaire 1 is inappreciable by the change of influence of light element 22.
Previous described three possible position S1 to S3 that are suitable for influence of light element 22 are presented among Fig. 5 to Fig. 7 again, and in this case, in these schematic diagrames, only display light influences element 22 with respect to the setting of reinforcing profile 14.
Handle for the ease of the assembling of the second influence of light element 22 and/or adjusting and for it is configured to be easy to, preferably the mode that snap action bindiny mechanism 31 can be rotated between its position S1 and S2 with the second influence of light element 22 forms the hinged or joint 33 of rotation.If for example because the tightness of snap action bindiny mechanism can additionally be fixed influence of light element 22 at optional position of rotation, then optionally realize position of rotation and influence of light position.
The second influence of light element 22 is adjusted to position S3 or is from the other possibility that position S3 is adjusted to position S2 from position S2, influence of light element 22 is separated, and it is basically parallel to rear wall or in the imaginary plane that rear wall extends, rotates 180 °, then it is reconnected in snap action bindiny mechanism 31.
Therefore, for simplifying and being convenient to the purpose assembling or dismantle, preferably by clamping or locking plug bindiny mechanism, for example locking bindiny mechanism or plug/connecting mechanism for rotating is realized quick-connect machanism 31, shown in exemplary embodiment.
Described locking bindiny mechanism is by the lockweight 31a that preferably has circular cross-section and can form by two locking pawl 31b of elastic atresia on lockweight 31a.Under the situation of exemplary embodiment, lockweight 31a is being by reinforcing on the profile 14, the preferred web on its lid 15, be arranged on upwards open, part is in the columniform groove, and locking pawl 31b is arranged on the relevant edge of influence of light element 22.Locking realizes like this: locking pawl 31b elasticity when inserting ejects, and under the insertion state, be clamped in automatically with triggering lockweight 31a back some.Lockweight 31a firmly is connected to its supporting body by little connection web 31c.Consider to connect web 31c width smaller, the distance along the circumference direction between the locking pawl 31b is very big, and makes influence of light element 22 to rotate between position S1 and position S3.
For influence of light element 22 is regulated between its position S1 and S3, need previous described 180 ° rotation, in this case, influence of light element 22 reaches locking again with separated, rotation.
This structure makes preferably that at reflection position S1 influence of light element 22 is prevented from or limits towards cladding element 23 rotations, is namely realized with being connected the stop position between the web 31c by relevant connection pawl 31b.
Under the situation of exemplary embodiment, the wall of influence of light element 22 comprises into two wall parts of obtuse angle W3, and the summit 22a at this obtuse angle is positioned at the inward flange top of second light emitting area 21 substantially.The inner region of influence of light element 22 is used for holding locking pawl 31b in this case, and simultaneously on the other hand, exterior domain also for example can be by anodization, so that its tarnish as reflector or diffusing surface.
Under the situation of exemplary embodiment, locking bindiny mechanism or integral joint 33 are arranged in covers 15 edge or folding corner region.
Under the situation of exemplary embodiment, the joint 25 that is used for covering wall 23 is formed between the upper edge region and supporting leg 15b of relevant profile supporting leg 14b, and supporting leg 15b is from covering 15 obliquely outwards, extend upward, and forms the groove supporting leg 25c that is correlated with simultaneously.Therefore, joint 25 is arranged between relevant profile supporting leg 14b and the lid 15.
Second light emitting area 21 and cap member 23 and the second influence of light element, 22 preferred size or the length L laterally extending with respect to drafting face that spread all over housing 2 of extending.This also is applied to the situation according to the elongated form of the luminaire 1 of Fig. 4.
The second influence of light element 22 and cladding element 23 and relevant blank area (be lockweight 31a and locking pawl 31b at this, and groove supporting leg 25c) are preferred continuous and laterally extending as the crow flies with respect to the figure paper.These parts therefore can be at an easy rate as shaped portion production, for example by stretching or pushing each long semi-finished product and it is cut to certain-length.
Fig. 8 shows the variant embodiment according to luminaire 1 of the present invention, it correspondingly is devoted to short suspension height, wherein in this case, the inner region of influence of light element 22 is selected as making it to have bigger surface, thereby increases the ratio of direct light owing to the reflection of light at the inner region place of this corresponding formation.By selecting euphotic cover 21 by the overlapping size of the inner region of influence of light element 22, the ratio of the light of guiding ceiling into is specifically reduced, and the spill exterior domain of influence of light element 22 is correspondingly guaranteed to be distributed on the ceiling widely by the light of its reflection.
