Description

The present invention is based on a designed according to the preamble of the main claim lighting arrangement.

Such lighting arrangements are intended to realize a needs-based illumination of their assigned lighting area. In order to avoid unnecessary dazzling of the persons staying in the lighting area, the light radiation of such lighting arrangements is often not emitted directly, but rather via a reflector and a demand-oriented light exit area to the outside, which is often provided with a light-permeable cover. Such lighting arrangements can be embodied, for example, as recessed luminaires, recessed luminaires, pendant luminaires, etc., and are often provided for attachment to a ceiling. In particular, such lighting arrangements are used to illuminate goods, workplaces, business premises, corridors and other interiors of buildings.

An according to the preamble of the main claim lighting arrangement is characterized by the DE 20 2006 005 920 U1 known. Such a lighting arrangement has a housing in which a light-emitting means insert is arranged, which on the one hand is provided with a lighting means and which, on the other hand, is in communication with the electrical / electronic components necessary for connection and operation. At least one light-permeable cover assigned to the light exit region is attached to the housing. The light source of this lighting arrangement is designed as a fluorescent lamp. For mounting the bulb insert is inserted in the longitudinal direction in the illuminant chamber of the housing. For heat dissipation, the bulb insert comes into contact with the inner walls of the housing. Often there is a desire, in such a lighting arrangement, to be able to make the mounting of the illuminant insert transversely to the longitudinal direction of the housing running. In addition, it is often important that care is taken for a particularly good heat dissipation of the lamp insert to the housing. However, such requirements are difficult or impossible to meet with such a trained lighting arrangement.

EP 0813027 discloses a lighting arrangement corresponding to the preamble of the main claim.

Based on such an embodiment, the present invention seeks to provide an illumination arrangement in which in a particularly simple manner, the mounting of the illuminant insert transversely to the longitudinal direction of the housing - namely on the light exit area - the illuminant chamber can be carried out and at the same time by the Mounting a particularly good heat dissipation of the lamp insert is secured to the housing.

According to the invention this object is achieved by the features specified in the main claim.

Particularly advantageous in such an embodiment is that at the same time simple and comfortable installation of the lamp insert in the housing is a particularly uniform, thermal connection over large areas and by the weight of the lamp insert high investment forces are generated. It is also particularly advantageous that a particularly secure attachment of the lamp insert is guaranteed in the housing, because the attachment via positive engagement with high holding forces. The use of springs is thus advantageously not necessary.

In addition, it is advantageous when using LEDs as bulbs that the luminous intensity and / or the light color of the individual, designed as LED bulbs by an electronic control device as needed for each light source or for different groups of bulbs is selectively adjustable, so that the emitted luminosity and / or desired light color can be varied as needed in a simple manner. In addition, the use of LEDs as light sources results in a particularly homogeneous light distribution because no dark areas occur within the lighting arrangement.

Furthermore, it is particularly advantageous that the lighting arrangement is constructed in a modular fashion from a housing, at least one illuminant insert and a light-permeable cover. The housing and the translucent cover can be modularly easily produced in several lengths of continuous material. The illuminant inserts can also be produced in a modular manner in different lengths as required in a simple manner.

Figure 6:

in principle, a second embodiment of such a lighting arrangement as a piece without end caps spatially in the final assembly state with translucent cover.

As can be seen from the figures, such a lighting arrangement essentially comprises a housing 1 consisting of an elongate profile.

The housing 1 has a luminous means chambers 2, which extends in the longitudinal direction over the entire length of the housing 1 and which is closed on its underside with a translucent cover 3 to the outside. The illuminant chamber 2 can be equipped with at least one illuminant insert 4. The translucent cover 3 is part of the light exit region of the illuminant chamber 2 of the housing first

As further shown in the figures, the housing 1 consists of a single piece of aluminum profile. The housing 1 is made in one piece and separated in terms of its length as needed by an aluminum strand (aluminum profile).

The illuminant insert 4 consists of two inserts 4A, 4B, which are connected to each other via a mechanism. The mechanism has a support profile 6, which forms the central pivot bearings LA, LB for the two insert parts 4A, 4B. In addition, the mechanism has a guided on the support profile 6, the two first free end portions EA, EB of the two insert parts 4A, 4B hingedly interconnecting, latch assembly 5. Each of the two insert parts 4A, 4B has to form the central pivot bearing LA, LB integrally on a bearing rail 8A, 8B, each extending in the extension direction of the housing 1 and each with a correspondingly extending, integrally molded into the two narrow sides of the support section 6 bearing groove 9A , 9B cooperate. The bearing rails 8A, 8B of the two insert parts 4A, 4B are each arranged approximately centrally with respect to the overall height of the two insert parts 4A, 4B, so that per insert part 4A, 4B, two roughly equal pivoting sections are formed. The two insert parts 4A, 4B each have in one piece a main leg 10 and, projecting at an angle from this reflector leg 11. The two inserts 4A, 4B consist, like the housing 1, of a single piece of aluminum profile, which is separated in terms of its length as needed by an aluminum strand (aluminum profile). In interaction, the two reflector legs 11 form a roof-shaped arrangement, in the illuminant chamber 2, so that the light generated by the light source 12 is supplied as needed to the light exit area and ultimately discharged through the translucent cover 3 to the outside. For needs-based influencing the translucent cover 3 with appropriate light influencing means such as microlenses, colorations, coupling-out structures, etc. be provided. The translucent cover 3 can be fixed in two different positions on the housing 1. For this purpose, four longitudinal locking grooves 14 are formed in the housing 1, which cooperate with appropriately designed, integrally formed on the cover 3, 15 Rastwülsten. If necessary, the reflector legs 11 may have a shape design to produce certain light distribution curves of the bulb insert 4. Form designs, such as, for example, a parabolic, hyperbolic, etc. course are possible.

Several lamps 12 are arranged on a printed circuit board 13 and designed as a light emitting diode (LED). The stocked with the bulbs 12 circuit board 13 is fixed to the, the translucent cover 3 facing the main surface of the support section 6.

The latch assembly 5 consists of three, mutually articulated, bolt struts 5A, 5B, 5C. The three bolt struts 5A, 5B, 5C of the bolt arrangement 5 are arranged in a T-shape and are connected to one another via a common first joint point G1 assigned to their three first end areas. The two locking struts 5A, 5B are connected via their second free end regions in each case by a second joint G2 articulated to one of the two inserts 4A, 4B. The second free end portion of the third tie bar 5C has an orientation tapering toward the translucent cover 3. With respect to the translucent cover 3, the two second hinge points G2 are arranged above the support profile 6. In this case, the two bolt struts 5A, 5B connect the two first free end regions EA, EB of the two insert parts 4A, 4B. The free end region of the third locking strut 5C protrudes in its extension beyond the support profile 6 and serves the user as an actuator for locking and Endriegeln.

As further, in particular from the FIGS. 1 to 5 shows, the support section 6 has two on an inner surface of the two insert parts 4A, 4B of the lamp insert 4 coming to rest, cooling leg 6A, 6B. The two Cooling limbs 6A, 6B are each formed below the bearing groove 9A, 9B on the two narrow sides of the support profile 6, these extending in the direction of the light-permeable cover 3. They serve the purpose of providing for a particularly large-scale investment of the support section 6 to the two insert parts 4A, 4B, so that the heat generated during operation is released from this as quickly as possible to the housing 1. In a simple and convenient installation of the light bulb 4 in the housing 1 is at the same time a particularly uniform, thermal connection of the bulb 4 realized over large areas of the housing 1 and the support section 6. In addition, the two middle pivot bearings LA, LB with their bearing rails 8A, 8B and bearing channels 9A, 9B contribute to heat being transferred from the support profile 6 to the two insert parts 4A, 4B. Advantageously, a particularly secure attachment of the lamp insert 4 is ensured in the housing 1, because the attachment via positive engagement with high holding forces. The holding or contact forces are generated without springs on the weight of the light bulb insert 4.

FIG. 1 shows the illuminant insert 4 during its assembly in the housing 1. The illuminant insert 4 has already been inserted from below, that is, above the light exit region, completely into the housing 1. The insertion direction is transverse to the longitudinal direction of the housing 1. The latch assembly 5 is not limited in their mobility. If the illuminant insert 4 is now pushed further into the housing 1 by the user, the latch arrangement 5 comes into abutment with its first articulation point G1 on the associated inner surface of the housing 1. Upon further insertion, the latch assembly 5 is pressed more and more down, thereby simultaneously the two inserts 4A, 4B are pivoted about their central pivot bearings LA, LB and the main leg 10 intimately come to the associated inner walls of the housing 1 to rest. The illuminant insert 4 is thus, as in FIG. 2 shown securely fixed in the interior of the housing 1. Finally, the fixing screw FS is tightened, whereby the bolt strut 5C set to secure the support section 6 and the mobility of the latch assembly 5 is locked. The final assembly state is thus achieved. In addition, to ensure, for example, by a, molded into the bolt strut 5C, bead ensures that the latch assembly 5 is not unintentionally transferred to an unstable position. Advantageously, results from such a bead for the user a tactile feedback that the position assurance for the latch assembly 5 is present.

FIG. 3 shows the bulb insert 4 during its disassembly from the housing 1. After loosening the fixing screw FS, the mobility of the latch assembly 5 is restored. If the user now pulls on the latch strut 5C, the two latch struts 5A, 5B are moved downwards via the first hinge point G1, whereby simultaneously the two insert parts 4A, 4B are rotated about their central pivot bearings LA, LB and the main legs 10 are again separated from the associated ones Inner walls of the housing 1 are removed. In addition, the barrier created by the bead, which is not shown for the sake of simplicity, must be overcome. Finally, the positive connection between the housing 1 and the illuminant insert 4 is canceled, whereby a simple disassembly is ensured for the user, because the illuminant insert 4 can be easily removed via the light exit region down from the housing 1.

The fixing screw FS can, in order to simplify the assembly further, also be replaced by a, the securing of the final assembly state ensuring latching mechanism. In this case, such a locking mechanism, for example, according to the operating principle of a ratchet, a latching cam assembly, a keyhole arrangement, etc. work.

By such a configured lighting arrangement is thus advantageously a tool-free, or largely tool-free, assembly and disassembly of the bulb insert 4 as described above possible.

As in particular from FIG. 4 and FIG. 5 shows, each bulb 4 has two, attached to the two ends, bolt assemblies 5, so that the user in a simple way with both hands, the assembly and disassembly of the bulb 4 can make as described above. Of the FIG. 5 In addition, it can be seen that a plurality of light-emitting diodes 12 (LED) are arranged on a printed circuit board 13. The printed circuit board 13 is fixed to the, the translucent cover 3 facing the main surface of the support section 6. What is important is that of the bulbs 12 generates heat as quickly as possible derived on the support section 6 and is then discharged via this on the two inserts 4A, 4B to the housing 1. By the above-described embodiment of the lighting arrangement, this is particularly effective possible. As further from the FIGS. 4 and 5 As can be seen, the two reflector legs 11 in interaction form a roof-shaped arrangement, so that the light of the lighting means 12, as already described above, is supplied as needed to the light exit area of the lighting arrangement. As already described above, the reflector legs 11 may, if necessary, also have a different shape.

In the FIGS. 1 to 5 is the first embodiment of such a lighting arrangement shown in more detail, where, however, in the FIG. 6 the second embodiment is shown in more detail. Apart from another way in which the heat generated by the bulbs 12 is delivered from the support profile 6 to the two insert parts 4A, 4B, the construction of the illumination arrangement according to the second embodiment is also as described above for the first embodiment. In contrast, as well as further particular FIG. 6 It can be seen that the two insert parts 4A, 4B with their second free end portions EC, ED of their reflector legs 11 in the final assembly state, the, the translucent cover 3 facing the main surface of the support section 6 intimately to the plant, so that also on these surfaces good heat dissipation to the housing. 1 is effected. In addition, the heat generated by the bulbs 12 is delivered to the support section 6 and transmitted via the two central pivot bearings LA, LB to the two inserts 4A, 4B. From the inserts 4A, 4B, the heat is then dissipated to the housing 1. The two middle pivot bearings LA, LB with their bearing rails 8A, 8B and bearing troughs 9A, 9B are designed to be comparatively large in construction and, when combined, have particularly small dimensional tolerances. Thus, even in this second embodiment of such a lighting arrangement is ensured that the heat generated by the bulbs 12 is particularly effective on the support section 6 and the two inserts 4A, 4B on the housing 1 is derived.
