Description
The present invention relates to according to the lamp of the preamble of claim 1, it is especially provided for being arranged in ceiling and/or wall and has the lamp housing and the inside casing being connected with housing that holds luminescent device for this reason.The invention particularly relates to so-called Projecting Lamp.
At its housing, be for example arranged in the concealed installation lamp in the perforate of suspended ceiling, conventionally by special-purpose frame unit, install and be provided for the cover plate that light penetrates, this frame unit can be fixed on housing.Frame unit now for example by thread connection, bayonet socket, connects or quick-action clamping is fixed on housing, and wherein it can split by corresponding instrument and housing again subsequently.In order to allow to approach lamp housing inner chamber, the demountable structure of frame unit and cover plate is essential.For example approaching like this may be essential for carrying out the luminescent device that maintenance activity or replacing be arranged in housing.
Because lamp can only approach from bottom side in its installment state, so especially can simply frame unit be pulled down together with cover plate without corresponding tool as far as possible, be favourable.WO 2006/037572A1 discloses a kind of downlight to this, is wherein provided with special locked mechanism, and it works to keep for example cover plate between case frame and functional framework.Here, the critical piece of locked mechanism is metal wire spring, and it forms locking piece at its petiolarea, and this locking piece coordinates with the lock groove in functional framework.Now so form line spring and lock groove, that is, the locking and unlocking of functional framework respectively by having exerted pressure framework on its closing direction.By this so-called pushing locking release mechanism (Push-Push Verschlussanordnung), allow simple especially locking and the release of practical function framework.
Now, task of the present invention is, in view of above-mentioned prior art, improves for respective frame part is fixed on to the possibility on concealed installation lamp.
This task completes by having the lamp of the feature of claim 1.Favourable improvement project of the present invention is the theme of dependent claims.
Solution of the present invention also based on following idea, that is, provides a kind of lock solid structure with locking mechanism, for realizing, detachably frame unit is fixed on to lamp housing.But according to the present invention, locking mechanism has solid latch hook now, and this latch hook and mating member are worked in coordination, and the so movable setting of this latch hook, that is, this latch hook can move between locked.
According to the present invention, a kind of lamp is correspondingly provided, concealed installation lamp in particular for ceiling and/or wall, it has lamp housing, within this lamp housing is provided for being arranged on wall or ceiling or on and for holding luminescent device, wherein, this lamp also has the inside casing that is especially used for keeping optical element, this inside casing can be pulled down and connect with this housing on installation site by lock solid structure from housing at least partly, wherein this lock solid structure has locking mechanism, inside casing locks together in installation site and this housing by this locking mechanism, and the locking of described inside casing just can be removed without instrument.The present invention's regulation, locking mechanism has solid latch hook, and this latch hook coordinates with mating member and movable setting, so that described latch hook can move between locked.Especially, this latch hook can rotatable support.
Now, owing to replacing spring element to adopt solid latch hook to connect separably inside casing and lamp housing, therefore improved the connection between housing and inside casing.Why very meaningful this is, is because locking mechanism also must bear framework and the weight that is fixed on the member of framework completely when lamp is loaded in ceiling.By using solid latch hook, the much higher inside casing that its weight ratio can be able to be reached so far is now fixed on lamp housing together with optical element.Even if with larger light exit and then with the lamp of larger outgoing cover (its weight not noticeable), also corresponding the reliable fixing of built-in frame of having realized.
The latch hook of locking mechanism of the present invention is preferably placed on housing or inside casing and with the mating member being placed in opposed members (inside casing and housing in other words) and coordinates.This mating member here can have on the one hand in latched position and the sealed locking of latch hook projection with have on the other hand guiding crescent, on the contrary this guiding crescent be used for guiding latch hook from latched position move to unlocked position or.Now, latch hook can especially truely coordinate with mating member, that is, the locking and unlocking of inside casing all by exerting pressure to realize to inside casing on closing direction.In solution of the present invention, correspondingly preferably by comfortable especially pushing locking release mechanism, carry out the locking and unlocking of implementation framework.
In addition, locking mechanism also can have spring element, and latch hook is tightened to latched position or unlocked position in advance by this spring element.But different from the solution described in WO 2006/037572A1, here spring element does not bear the gravity of framework.The substitute is, in the present invention, framework is only by keeping with the sealed latch hook of mating member.
Framework preferably so forms, that is, this framework is within installation site is substantially disposed in housing.Especially can expect form fit layout arrangement, it makes to form lamp outward appearance attractive in appearance especially.
In addition, framework can be pulled down from housing completely, and in the case, at least two sides respect to one another that are preferably in housing are provided with locking mechanism.But only also can expect, in a side of framework, locking mechanism to be set, and this framework is connected with lamp housing by hinge rotationally in a relative side.Although framework now can not be pulled down completely, at least can so rotate, so that can approach the inside of the lamp that luminescent device is housed.
As mentioned above, inside casing is preferred for keeping light intervention portion.Light intervention portion can be for example the cover plate of at least part of printing opacity or other light intervention portion penetrating for light.Also reflector can be set on inside casing.
Below, in connection with accompanying drawing, describe solution of the present invention in detail, wherein:
Fig. 1 and Fig. 2 are the different perspective views of downlight of the present invention, and this downlight comprises housing and is arranged on detachably the inside casing on this housing;
Fig. 3 represents lamp of the present invention, and it is in the inside casing state separated with housing;
Fig. 4 is the detail view of the locking mechanism that adopts in lamp of the present invention;
Fig. 5 a-Fig. 5 d is the view of each part of locking mechanism of the present invention; And
Each part that Fig. 6 a-Fig. 6 f represents locking mechanism is fixed on lamp housing and situation when lamp housing is removed at inside casing.
Fig. 1 and 2 represents that it forms so-called Projecting Lamp according to the view of the downlight of the present invention's formation.But this be it is to be noted, the present invention is not necessarily confined to this concealed installation lamp.Also the locking mechanism of detailed description also can be used in lamp, especially be used in lamp affixed to the ceiling, wherein, in lamp housing, should fix a frame unit for keeping additional optical element later.
First the overall concealed installation lamp representing with mark 1 has box-like lamp housing 2, and it defines light perforation hole at its front end.In front side, also form the protruding framework of side 3, this framework is against bottom surface or the outer surface of ceiling or wall in housing 2 installment states, and all the other housings are through ceiling perforate or wall perforate.At this, by unspecified securing member, housing 2 is fixed on wall or ceiling.Housing 2 is particularly useful for holding luminescent device and for driving the drive unit of luminescent device.At the back side of housing 2, form a plurality of cooling fins 4, the heat that they are distributed by luminescent device for faling apart.
Towards above, housing 2 should pass through transparent cover closure as far as possible, to realize light on the one hand, sends, and prevents on the other hand entering of dust or dirt and moisture.At opposite side, must there is following possibility, within the scope of maintenance activity, obtain and approach the approach of lamp inside, to for example change luminescent device.Because can only be from approaching above, so cover plate does not directly connect with housing 2 in the installment state of lamp housing 2.The substitute is, use inside casing 10 for this reason, (accompanying drawing is not shown specifically) cover plate is installed on this inside casing, and this inside casing is removably fixed on housing 2.Inside casing 10 now also can be used to keep for example reflector of other optical element, intervenes whereby the ejaculation of the light being sent by luminescent device.
Now, according to the present invention, inside casing 10 is connected with lamp housing 2 by lock solid structure, and this lock solid structure allows from housing 2, to pull down inside casing 10 simply.In this way, can obtain the path that approaches lamp housing 2 inside.
, so form lock solid structure here, that is, allow inside casing 10 to separate completely with lamp housing 2.For this reason, in the opposite sides thereof of lamp housing 2, be provided with two locking mechanisms, can inside casing 10 and housing 2 is sealed by means of described two locking mechanisms.Locking mechanism now so forms, and by exerting pressure towards 2 pairs of inside casings 10 of housing, realizes respectively locking or release.By so-called pushing locking release mechanism (Push-Push Mechanismus), realized especially simply, especially without framework 10 the locking and unlockings of instrument.As shown in Fig. 3 signal, only framework 10 always need to be laid or is depressed on lamp housing 2 along the direction of arrow.Below with reference to other accompanying drawing explanation, realize the locking mechanism embodiment of this point.
Fig. 4 illustrates the chief component of locking mechanism 30 for this reason, and wherein it is latch hook 35 on the one hand, is the mating member 40 of working in coordination with latch hook 35 on the other hand.Latch hook 35 is fixed on the sidewall of lamp housing 2 by securing member 50, and mating member 40 is formed on the arm 11 that protrudes from inside casing 10.But also can expect the arrangement that these parts are changed each other in principle.If at that rate, latch hook just will be arranged on inside casing.
The tabular securing member 50 that Fig. 5 a is shown specifically is in order to keep latch hook 35 first to have the pin 51 that side direction is outstanding.Pin 51 is divided into two parts and in its end, has the projection 52 that side direction is outstanding, described projection is outstanding in side direction after running through the opening 36 being formed in this latch hook, thereby latch hook 35 is fixedly supported upon on pin 51 and correspondingly and can rotates around the axle perpendicular to securing member 50 orientations.In addition, also form pin 37 on latch hook 35, this pin inserts in the long arc-shaped holes 53 of securing member 50, thus the swing of latch hook 35 is restricted in certain limit.Fig. 5 d also illustrates wing spring 55, and this wing spring is arranged on securing member 50 end regions that are oppositely arranged with slotted hole 53 and for this reason with the corresponding breach 54 of its end regions 56 insertion corresponding to the view of Fig. 4.Spring 55, especially its central elevation 57, work in coordination with another projection 38 being formed on latch hook 35.At latch hook 35, be arranged in the state on securing member 50, this causes latch hook 35 or is tightened in advance latched position, or is tightened in advance unlocked position, and here, the conversion between these two positions so realizes, and, rotates latch hook 35 that is, so that projection 38 is through protuberance 57.Finally, form hook 39 on the front end of latch hook 35, this hook is worked in coordination with particular form and mating member 40, for realizing, pushes locking release mechanism.
Mating member 40 so forms itself, forms locking projection 41 on the one hand, forms on the other hand the guiding crescent 42 of arc.Two members are that locking projection 41 and guiding crescent 42 coordinate with latch hook 35 in the following manner.For this reason, in the housing 2 of lamp 1, form corresponding through hole, the arm 11 of framework 10 is through this through hole, thereby mating member 40 contacts latch hook 35 as depicted in figs. 1 and 2.
If inside casing 10 will be fixed to housing 2 now, first according to the view of Fig. 6 a, from the front of housing 2, inside casing 10 is placed to this housing, exactly so lay,, arm 11 inserts and is formed at the perforate in housing 2, and the hook 39 of mating member 40 corresponding contact latch hooks 35, and this latch hook is now positioned at such position, in this position, this latch hook is tightened to locking predeterminated position (in figure towards a left side) in advance by spring 55.
In this case, by the ramped bottom surface 41a of locking projection 41, hook 35 deflection a little (Fig. 6 b), but degree is slight, thus it is tightened to locking predeterminated position with in the past the same in advance by spring 55.If now inside casing 10 is further pressed to housing 2, the hook 39 of hook 35 can passed through locking projection 41 sometime, and subsequently again because spring force makes hook 35 continue outwards to rotate, thereby projection 41 is lived in hook 39 overhead kicks, now latch hook 35 and mating member 40 sealed (Fig. 6 c).Do not use instrument, can correspondingly make in this way inside casing 10 and lamp housing 2 sealed.The gravity of inside casing 10 is now only born by latch hook 35, therefore for inside casing 10 together with the very heavy situation of the optical element being fixed thereon, guaranteed fixing reliably.
If unload inside casing 10 from housing 2, only need further framework 10 to be pressed to housing 2.Consequently: now, latch hook 35, because the arc design of guiding crescent 42 turns to unlocked position, bears right moving in other words in the view of Fig. 6 d.Protuberance 57 and present latch hook 35 that the degree of rotating now can be crossed spring 55 to the projection 38 of latch hook 35 are greatly tightened to unlocked position in advance, in other words pretension to the right.In addition, because hook 39 is no longer hooked projection 41 now, so inside casing 10 can be separated with housing 2.In the case, the lower slider face 43 of the inclination of guiding crescent 42 is also responsible for, and before soon inside casing 10 is separated with housing 2 the most at last, makes again latch hook 35 rotate towards left side, and makes this projection through the protuberance 57 (Fig. 6 e) of spring 55.In other words,, when be fixed on housing 2 on by inside casing 10 next time, latch hook 35 has been positioned at again the tram shown in Fig. 6 f automatically.
In content, can know from the above description, locked mechanism according to the present invention has been realized very simple inside casing 10 fixing or splitting with lamp housing on lamp housing.In addition,, by the special embodiment of locking mechanism, realized framework fixing on housing very reliably.
In addition, as substituting of described embodiment, also can expect, locking mechanism is only formed on framework one side, and framework connects with housing by hinge at opposite side.In the case, framework possibly cannot be completely separated with housing, but only separated in a side and then rotate, from and can approach lamp inside.
