The lighting device that embodiment of the present utility model is made up of some multiple similar support modules.Each module supports an independent light fixture, and self comprises light fixture: a reflection shield Support bracket, a bulb (bulb can merge with reflection shield) and electronics connector.These modules comprise a rectangular frame (preferably square) separately, and framework in use is connected to a side (or for example be connected to isolating frame by Fig. 6 and 7 in some occasion or be connected by isolating frame) of another adjacent frame along a side of framework.The connection that produced structure makes all sides of framework lay connector so that use identical module can produce the arrangement group of different choice and releasably link together by user's requirement.

With reference to accompanying drawing, each support module 10 is made up of the square stainless steel frame of an opening among Fig. 1, and framework has two holes 11 that form at each side.Each hole 11 is formed with cavity 12, it lay and contain an elasticity bayonet lock 14 shoulder 13 (see figure 5)s in case the side of framework can be releasably, securely, be fixed together along their length direction with leaning on mutually.

Each module explains that with reference to Fig. 3 and 4 method hereinafter supports a light fixture 15 (only a light fixture is presented among Fig. 1) with a kind of more completely.Cable clamping plate 16 are described to be fixed on the module by accompanying drawing, are fixed together with corresponding module when the shaping of clamping plate is used in position with box lunch.The cable clamping plate are fixed by bayonet lock 14 and can be removed from module in position and when bayonet lock 14 has been removed.

In Fig. 2, same module 10 links together by row with the arrangement group of four modules.Two types of the mounting arrangement of Fig. 2 display illumination device.Each mounting arrangement comprises an analog bracket 17, and it is fixed on a pair of adjacent module by the bolt 18 that passes hole 11 separately.This means that analog bracket 17 also can be used in is fixed together module 10.It should be noted that,, then do not need the special assembling part to admit analog bracket 17 and bolt 18 because hole 11 has been formed on the tram in the module 10.Mounting arrangement had not only had two arms 19 but also had had two rigid filaments rod connectors 20 (or can have two in one by diagram) and extended between analog bracket 17 and the wall mounting bracket 21.Should be understood that any wall that described mounting arrangement is fixed thereon support 21 in use or other the similar structure in the fractionation of lighting device and orientation and allow sizable flexibility ratio.In this respect, fix in place by flat head screw 22, quite easily screw mandrel connector 20 is cut into suitable length (perhaps when needs, screw mandrel being prescinded) when the end of screw mandrel connector 20.

Fig. 2 goes back display power supply distributing board 23, and it comprises: lay a socket 24 of external power supply, be used for four supply sockets 25 of light fixture, one of these supply sockets are joined plug 26 and are shown in place.The flexible cable of Xian Shiing does not in use extend to each corresponding light fixture and pushes clamping plate 16 by the suitable cable that is presented at Fig. 1 from plug 26 and fixes in place.It should be noted that distributing board 23 is fixed on the top of pair of modules 10 sides and will be fixed in place by elasticity bayonet lock 14.

In Fig. 3 and 4, can see how each light fixture 15 is installed on its module 10.The minor axis elasticity of inwardly stretching out folder 27 remains on the opposed side of module 10 by hold-open catch, and it holds the axle 28 that is installed on the outer shroud 29.Ring 30 is pivotally connected to outer shroud in one, makes them to revolve axle by being depicted in of dotted arrow among Fig. 3 and goes up rotation.(therefore, the effect of two ring 29 and 30 formation " star coupling " between each light fixture 15 and module 10.)

As shown in Figure 4, importantly light fixture can be easy to dismounting.If enough spaces are not clamped and be equipped with to power supply supply cable (not shown), light fixture just can partly be dismantled.If feed cable is not plugged, light fixture just can be dismantled fully.In all case, light fixture 15 can both easily unclamp and dismantle (we can say and only use a hand) so that keep in repair, and more generally reaches the bulb that more convenient replacing one is scrapped.When maintenance has been finished or new bulb when having installed, light fixture 15 is pressed into and is got back to correct position in the module 10 by folder.

Should understand, in many commercial uses and/or in use as many electric lights, one that determine, how much be shorter than the service life of the ordinary life that they judge after, change the content that all bulbs usually are ordinary maintenances, no matter that bulb is scrapped or do not scrap.The dismountable installation of described light fixture significantly reduces more change the bulb required time and strength.

Be presented at " sample spare " elasticity bayonet lock 31 in addition among Fig. 4.It mainly is cause for aesthetics that elasticity bayonet lock 31 is provided.It is identical that elasticity bayonet lock 31 is made (in fact bayonet lock 14 can be made equally) also painted color with module 10 materials by appropriate plastic material usually.Therefore resilience bayonet lock 31 makes the cavity 12 of naked-eye observation less than no hole 11.When scheme optimization, bayonet lock 14 can be made so that provide color to the limit of exposing of module 10 by the material of contrastive colours.

Fig. 5 shows the arrangement group of five modules 10 by cross shape.Have only a light fixture 25 to show in the drawings.Module 10 uses elasticity bayonet lock 14 removably to be fixed together as before.Feed cable wireplint and distributing board (not shown) are arranged usually, as explanation about earlier drawings.

Fig. 6 shows the arrangement group of the module 10 what are different, also only shows a light fixture 15.The triangle isolating frame 32 of one opening is placed between two modules.This isolating frame has the hole 33 of appropriate location and lays elasticity bayonet lock 14.Equally, Fig. 7 shows that another uses narrow triangle isolating frame 34 by elasticity bayonet lock 14 multi-form with its arrangement group that is connected with module 10.

Any amount of module 10 can removably be joined together to form selected arrangement group by explanation, and the use hypothesis need be as the isolating frame triangle isolating frame 32 and 34.In every kind of example, can make and provide same similarly module to make the user form the selected arrangement group of his uniqueness.The user also can usually change arrangement group (if he wishes), because module 10 can be opened at an easy rate.The example that also has is, supposes module 10 in practice by nuts and bolt, and perhaps other dismountable connector is fixed together.But described elasticity bayonet lock (or support) 14 has the advantage that they can make module be buckled together and draw back without hand-operated tools.

It should be noted that, for example can be used for supporting a transformer that substitutes light fixture at an a kind of module of arranging in the group.Because many bulbs require the low-voltage dc power supply supply, usually need transformer.In this example, transformer and distributing board are installed in the module, and suitable power supply supply cable is connected to light fixture from distributing board.The module that is used to support transformer has other " standard " framework 10 usually (or with the form of isolating frame, picture isolating frame 32), in order that " transformer " module can be in the manner described above in the arrangement group, be detachably connected to other framework 10 Anywhere.

In Fig. 8 and 9, to support module and comprise square plate-shaped frame 35, it can interconnect and form various arrangement groups.Each light fixture 36 (it can be identical with light fixture 15) is supported by U-shaped carriage 37 rotationally, and U-shaped carriage 37 is rotatably fixed in the hole 38 at framework 35 centers.Carriage 37 is connected to framework by the flexible hollow plastics pin 39 that is fixed in the hole 38.Carriage 37 can upwards push away, and therefore the hole (not shown) in the U-shaped bottom surface is slided on pin 39 and entered in the circumferential groove that is formed on the pin.In order to lay down carriage 37, the lower end of pin is moulded to sealing, and carriage skids off circumferential groove and makes carriage to lower slider and break away from pin 39 then.If necessary this action only uses a hand just can finish usually.

Fig. 9 shows how two modules 35 are stuck by clamping plate 40 fixing under the integrally formed flange 41 of module 35.Flange 41 extends along each side of module 35, thus these modules can along its arbitrarily and each side be joined together to another module, in the time of needs, form difform arrangement group.

Power supply supply distributing board 42 (generally being similar to the distributing board 23 among Fig. 2) in use is installed on the pedestal 43, and pedestal 43 is fixed on the last joint tongue 44 of clamping plate 40 by screw.The lower limb of pedestal 43 is bearing in the upper surface of module 35 downwards, and these upper surfaces are fixed in the plane that has.When pedestal was removed, these upper surfaces can deflection, so that remove clamping plate 40 and be separated from each other module from flange 41.

Module 35 can removably be fixed together and form various arrangement groups by explanation.Can use the suitable triangle or the isolating frame of other shape if desired.Just as before, use the lighting device of module 35 and carriage 37 to make the user can form and change the arrangement group on request.The light fixture 36 of joining carriage 37 is easy to dismounting, makes to keep in repair with more changing jobs of bulb and has no difficulty.

Should be appreciated that framework 10 is preferably square, but can use other rectangular shape.The side that the non-square shape of this class still can make module against and connect along their at least a portion of length direction, form the pleasing and durable combining structure on the aesthetics.Rectangle (comprising square) framework can be arranged by staged and connect, and promptly the total side of for example arrangement group becomes stepped in a direction or other directions.Framework can be made by appropriate plastic material or the metal except that stainless steel wholly or in part.
