The specific embodiment
At first, comprise inner underframe 12, closure member 14 and shell body 16 according to luminaire 10 of the present invention referring to figs. 1 through 4.
Underframe 12 has inner chamber 18, and inner chamber 18 has formed cover body, and the electronic-controlled installation (not shown) that lamp 20, reflector 22 and luminaire are used can be accommodated in this cover body.As seen from Figure 3, described inner chamber is provided with some mounting points 24, and lamp 20, reflector 22 and device supporting plate (geartray) (not shown) can be releasably attached to these mounting points 24.Mounting points 24 is arranged such that multiple different lamp, reflector and device supporting plate can be set in the described cover body.
Underframe 12 can adopt any suitable technology to make by any suitable material, and still, it is preferably by metal, and for example the aluminum or aluminum alloy casting forms.
From the plane, underframe 12 roughly is circular, and it has the circular sidewall of being roughly part 26, and sidewall sections 26 is sealed by the top 28 that is roughly taper.Flange portion 30 is radially outstanding outwardly from the lower limb of sidewall sections, and described lower limb defines the opening 32 of cover body 18.When lamp 20 and reflector 22 were in correct position in the cover body, the two was arranged such that the light from lamp is conducted through opening 32.Be provided with little opening 33 in top 28, cable (electricalcaballing) can pass through from little opening 33.Suitable hole circle (grommet) (not shown) can be used in the above-mentioned opening, and sealing is provided with the protection cable and around cable.
For make luminaire can be installed to supporter, such as on the lamppost, underframe 12 is provided with some mounting points on its outer surface.Wherein two mounting points provide by apparent first and second recesses 24,26 of underframe.Shown in Fig. 1 and 9, first of recess 24 provides lower mounting points, and this mounting points is suitable for holding support arm end or pipe (spigot) 34 ends that enter from the side.The sidewall 36,38 of this recess has installing hole 40, so that hold the securing member as bolt or screw (not shown), thereby underframe 12 is fastened on the described pipe.As can see from Figure 1, shell body 16 has the opening 41 that can allow support arm 34 therefrom pass, so that support arm 34 is connected on the underframe 12.Another recess 26 is constructed in a similar manner, and second, higher mounting points, this mounting points are provided also is in order to hold the support arm end that enters from the side or to manage 42 end, as shown in figure 10.
Other mounting points provides by two flat pieces 44,46, and flat pieces 44,46 is formed in the sidewall sections 26 in each side of underframe.Flat pieces 44,46 can be used to underframe 12 is connected on a pair of forked type supporting member, for example the member shown in Fig. 9.Other or optional mounting points can be provided as required.
Closure member 14 can be installed on the flange portion 30 of underframe 12, so that closing any opening 32, thereby lamp 20, reflector 22 and control device in the protection cover body.Closure member has: wheel rim 48, and when closure member was in its closing position, wheel rim 48 was near flange portion 30; With the transparent or semitransparent part 50 of inboard, can pass through this inside part 50 from the light of lamp.As shown in Figure 1, inside part can be from wheel rim 48 separated components, and can adopt various ways.For example, as shown in Figure 1, inside part 50 can be the form of insert of glass, plastics or the analog of general flat or low profile.Alternatively, this inside part can be the form of bowl 54, as shown in Figure 10.It will be apparent to those skilled in the art that the profile that can change inside part 50 as required, to cooperate the style of luminaire.
When closure member 14 was positioned at the appropriate location, seal 55 can be set between the flange portion 30 of the wheel rim 48 of closure member and underframe, thereby prevents that moisture and analog from entering cover body.This has guaranteed that cover body is round-the-clock fully.Also can between the wheel rim 48 of closure member 14 and inside part 50, the seal (not shown) be set.
In this embodiment, closure member 14 is connected to underframe 12 by hinge 56.This makes that closure member can be as shown in Figure 4 by swing open, so that dismounting or maintenance are installed in the parts in the underframe.When closure member 14 moved to its closing position, it was held in position by one or more releasable retainer (not shown), and described one or more retainers are operated between the wheel rim 48 of closure member and underframe.Preferably, described one or more retainers are eccentric (over-centre) type retainers, thereby guarantee that closure member is clipped on the underframe 12 tightly, with the sealing that provides.
In order to make closure member 14 can open enough greatly, so that the parts that are installed in the underframe can be by opening 32 dismountings, therefore, hinge 56 is a double-strand chain.The use of double-strand chain means that when closure member was opened, the wheel rim 48 of closure member can thoroughly get out of the way from the flange portion 30 of underframe.In Fig. 5 to 7, can be clear that the structure of this hinge.
Hinge 56 has first flap 58 of the flange portion 30 that is used to be connected to underframe and is used to be connected to second flap 60 of the wheel rim 48 of closure member 14.Shape roughly is inverted U-shaped demarcation strip 62 and extends between two above-mentioned flaps.Demarcation strip 62 is pivotably connected to first flap 58 by first pair of coaxial hinge pin 64,66, wherein, each pin be contained in an end in the joint 68 that is formed on demarcation strip top edge central authorities and a pair of joint 70,72 that on the outward flange of first flap 58, separates in corresponding one.Similarly, demarcation strip 62 is pivotably connected on second flap 60 by second pair of coaxial hinge pin 74,76.Described second pair pin 74,76 each all be housed inside be formed on inverted U-shaped demarcation strip the 62A of limb portion, 62B one of them the corresponding joint 78,80 of lower end and the outward flange of second flap 60 in the corresponding joint 82,83.Be formed with opening in the demarcation strip between two 62A of limb portion, 6B and central joint 68.
Because closure member 14 may be heavier and be difficult to handle, so first and second flaps 58,60 are provided with the guiding elements 84,86 that mutually combines, to guide closure member 14 with respect to the motion of underframe 12 between open position and closing position.First of guiding elements 84 is outstanding from first flap 58, and has first cam face 88.Second guiding elements 86 is outstanding from second flap 60, and has second cam face, 90, the second cam faces 90 with first cam face, 88 contacts on first guiding elements.Can be clear that from Fig. 7 A to 7C, first and second guiding surfaces are curves, and at the raised ends 92,94 and the narrower neck between end 92,94 and respective hinge plate 96,98 that define on these guiding elements towards the guiding elements end.
The operation of this hinge is described to 7C now with reference to Fig. 4 and Fig. 7 A.
Fig. 7 A shows when closure member 14 is in closing position, the relative position of first and second flaps 58,60, and at this moment, the wheel rim 48 of closure member is aimed at the flange portion 30 of underframe.When hinge is in this situation following time, the end 94 of second guiding elements 86 is placed in the neck area 96 of first guiding elements 84.As shown in FIG., first guiding elements 84 is outstanding by the opening in the separating plate 62, and this opening is limited by the 62A of limb portion, 62B and the central joint 68 of separating plate 62.
Hinge when Fig. 7 B shows closure member 14 and moves to the position that partially opens.In this position, the end 94 on second guiding elements 86 has advanced on the end 96 on first guiding elements 84.As shown, the lower end of demarcation strip 60 has been moved to the left an a small amount of with respect to it in the position shown in Fig. 7 A.Thereby second flap 60 and closure member 14 pivot with respect to demarcation strip 62 down around joint pin 74,76, thereby extend downwards with the angle of about 45 degree.
Fig. 7 C shows the hinge 56 that is in a fully open position.Can see that the end 94 on second guiding elements 86 is around 92 motions of the end on first guiding elements 84, thus the lower surface combination of heel end portions 92.In this position, as shown, further to left movement, and the inclination angle of second flap 60 is almost straight downwards with respect to the position shown in Fig. 7 A in the lower end of demarcation strip 62.Since the lower end of demarcation strip 62 to left movement, left the flange portion 30 on the underframe, so second flap 60 and closure member 14 have hung down, got out of the way fully the opening 32 in the underframe 12, make to be installed in the interior parts of cover body and can be removed.
When closing position was got back in closure member 14 motions, the relative motion of hinge member is reverse to be carried out.Therefore, when hinge 56 moves to position shown in Fig. 7 B from the position shown in Fig. 7 C, as shown, advance around the end 92 on first guiding elements 84 in the end 94 on second guiding elements 86, thereby cause second flap 60 and cause closure member 14 to move right with respect to underframe.Then, along with hinge moves to the position shown in Fig. 7 A from the position shown in Fig. 7 B, end 94 on second guiding elements 86 enters the neck area 96 on first guiding elements, thereby the wheel rim 48 of second flap 60 and closure member is in a controlled manner with the suitable aligning of the flange portion on the underframe 30.Now, can use the retainer (not shown) that closure member 14 is in position fastening.
Although in an illustrated embodiment, closure member 14 is connected on the underframe 12 by hinge 56 and one or more releasable retainer, yet, can closure member is fastened on the underframe by any proper device.For example, can not use releasable retainer, and use any suitable releasable fastener, as the securing member or the next fastening closure member of analog of spiral tapping.In addition, closure member 14 need not to be connected on the underframe 12 by hinge 56, and can be only by suitable releasable attachment means, and as the securing member or the analog of retainer, spiral tapping, perhaps the combination of these devices connects.
When closure member 14 was fastened to closing position, underframe 12 and closure member 14 provided round-the-clock cover body, and this cover body can be directly mounted on the suitable supporter 34.In order to improve the outward appearance of luminaire, suitable shell body device 16 is installed around underframe 12.Shell body device 16 can be the parts of single-piece as shown in Figure 1, perhaps can comprise the plurality of separate parts, and these separating components have formed the shell body that is used for luminaire together.
Because shell body 16 does not form the structure division of luminaire, therefore, can relatively inexpensively make shell body 16 by any suitable material (as aluminium or plastics).By using different shell body 16 and/or closure member 14, can change the outward appearance of luminaire 10.This means, can make multiple luminaire design, caused the reduction of manufacturing cost with general underframe 12.In addition, in case terminate the service life of luminaire, underframe 12 can be refreshed again, and uses together with new shell body 16 and new closure member 14, thereby produces brand-new substantially luminaire.Alternatively, the user can replace shell body 16 and/or closure member 14 simply so that the renovation luminaire, and need not replace whole unit.If necessary, replacing shell body 16 and/or closure member 14 can be different designs, to change the outward appearance of luminaire.Alternatively, shell body 16 and/or closure member 14 can be replaced with same parts simply, to prolong the life-span of luminaire.
Fig. 8 to 10 has illustrated how by using different shell body 16 with closure member 14 and by using different bracing or strutting arrangements to change the outward appearance of luminaire.
In Fig. 8, luminaire 10 shown in Figure 1 is connected to support arm 34, and support arm 34 is installed to the top of lamppost 100.In this embodiment, use the lower mounting points that provides by first recess 24 that support arm 34 is connected to underframe 12, as shown in Figure 1.
Fig. 9 shows luminaire shown in Figure 1 10, and luminaire 10 is installed between a pair of fork-type arm 102,104, and this is connected on the underframe 12 by the flat pieces on the sidewall 44,46 fork-type arm.
At last, Figure 10 shows the luminaire 10 ' that has optional enclosure body 16 '.Luminaire 10 ' is installed on the support arm 42, and support arm 42 is provided by the higher mounting points combination that is provided by second recess 26 on the underframe 12.In this embodiment, closure member 14 ' comprises glass bowl insert 54, and shell body device 16 ' is made of the housing parts 106,108,110 of plurality of separate.
