Embodiment
Fig. 2 shows two lamp sockets 1 according to first embodiment of the invention.Each lamp socket 1 is fixed in the given position of the body 260 of lighting apparatus 250, so that lamp 200 is attached to the installation site (suitable position) of lighting apparatus 250.That is, lamp socket 1 is used to limit the installation site of lamp 200 on lighting apparatus 250 and fixing in order to the lamp 200 that will place installed position.In the example of Fig. 2, body 260 is the shape of rectangular slab, and two lamp sockets 1 are fixed on the two ends of body 260 along its length.Body 260 also is provided with the ballast (not shown).On the other hand, lamp 200 is straight pipe type fluorescent lamps, and each end of fluorescent tube is provided with lamp holder 220, and two lamp bases that are used for powering (see Fig. 8 A 230) are outstanding from lamp holder along length (axle) direction of lamp 200.
As shown in Figure 3 and Figure 4, lamp socket 1 is formed by movement parts 2 and supporting member 6.Movement parts 2 has two contacts 30.Two contacts 30 correspondingly can and be electrically connected with two lamp bases, 230 contacts of the corresponding lamp holder 220 of lamp 200.Supporting member 6 support motion spares 2 make movement parts 2 to move between predetermined open position and off-position.
Supporting member 6 is formed by outer body 7 and outer cover 8, and they are respectively the synthetic resin moulded parts of being made by the resin material that is used to insulate.The resin material of outer body 7 especially has good sliding capability with respect to the resin material of interior body 4.Outer body 7 for example is a cylindrical shape, and it has correspondingly major diameter opening 70 and minor diameter opening 71 corresponding to large-diameter portion 4a and minor diameter 4b.Outer cover 8 is attached to major diameter opening 70 sides of outer body 7, makes movement parts 2 rotation between body 7 and the outer cover 8 outside.
The behind of antetheca 80 is formed with the rearwardly projecting U-shaped axle 801 from central authorities.That is, axle 801 has the slit that runs through that is bonded to directional slit 800.This runs through slit sets the random length that its size is longer than two lamp bases 230 in the insertion directional slit 800 for.In addition, the external diameter of axle 801 is set the spacing that its size is shorter than two lamp bases 230 for.Therefore, axle 801 is present between two lamp bases 230 that insert directional slit 800.When movement parts 2 merged in the supporting member 6, axle 801 inserted in the movement parts 2 through lamp foot jack 500, thereby between two contacts 30.
By placing supporting member 6 to form lamp socket 1 movement parts 2.As shown in Figure 2, the outer body 7 of supporting member 6 comprises base portion 74, base portion 74 is fixed in the body 260 of lighting apparatus 250 by using screw for example.In the example of Fig. 2, two lamp sockets 1 are fixed in body 260 makes the antetheca 80 of outer cover 8 be arranged to toward each other.Lamp 200 is attached to two lamp sockets 1 makes the end face of two lamp holders 220 correspondingly face two antethecas 80.
In lamp socket 1, movement parts 2 makes that by supporting member 6 supportings movement parts 2 can be around axle 801 rotations.The rotating range of movement parts 2 is subject to the size (described predetermined angular) of the operation window 72 of outer body 7.That is, the lever 43 of movement parts 2 is outstanding from operation window 72, and therefore can rotate in lever 43 touches the rotating range of edge of opening of operation window 72.In brief, the common rotating range of lever 43 and movement parts 2 is subject to the size (opening that is formed by otch 810 and operation window 72) of operation window 72.
The rotating range of movement parts 2 (θ 1) is limited between the position shown in the position shown in Fig. 5 A and Fig. 5 B.Position shown in Fig. 5 A is called " open position ", and the position shown in Fig. 5 B is called " off-position ".When movement parts 2 (lever 43) when being shown in an open position, the direction in the space from introducing port 42 to contact 30 is corresponding to the depth direction of directional slit 800.In this case, introducing port 42 links to each other with directional slit.When movement parts 2 was in the closed position, the depth direction of the direction in the space from introducing port 42 to contact 30 and directional slit 800 intersected.In this case, introducing port 42 is disengaged and utilizes the cylinderical surface (the sliding part 7a of outer body 7) of supporting member 6 to block with the opening (top) of directional slit 800.In the first embodiment, off-position is a movement parts 2 from its open position 90 positions when spending that turn clockwise roughly.In addition, the direction of the top of process directional slit 800 and bottom is corresponding to specific direction of the present invention.
Particularly, when movement parts 2 was shown in an open position, introducing port 42 overlapped with directional slit 800, and the lamp foot jack 500 of movement parts 2 is by introducing port 42, operation window 72 and otch 810 lateral open.Therefore, two lamp bases 230 800 can be inserted the lamp foot jacks 500 from introducing port 42 sides along directional slit, and lamp 200 can be placed the installed position of lighting apparatus 250.Otherwise, two lamp bases 230 can be extracted lamp foot jack 500 through introducing port 42 sides along directional slit 800, and lamp 200 can be removed from the installation site.In these cases, lamp for example is roughly parallel to the plane motion of the installation site that comprises lighting apparatus.
As shown in Figure 6A, when movement parts was shown in an open position, the direction in the space from introducing port 42 to contact 30 was corresponding to the depth direction of directional slit 800.Here, the spacing of contact 30 is greater than the diameter of each lamp base 230, and therefore, two lamp bases 230 that insert in the lamp foot jack 500 do not contact with contact 30 and are not electrically connected with contact 30.
Then, movement parts 2 is rotated to the position of Fig. 6 C via the position clockwise (seeing arrow A) of Fig. 6 B from the position of Fig. 6 A.When movement parts 2 was in the closed position, introducing port 42 left the opening of directional slit 800 and utilizes the cylinderical surface of supporting member 6 (the sliding part 7a of outer body 7) to block.Therefore, utilize movement parts 2 that two lamp bases 230 are blocked, and can not two lamp bases 230 be moved and extract lamp foot jack 500 along described specific direction.Therefore, after lamp 200 is placed the installation site of lighting apparatus 250, each movement parts 2 is moved to off-position, lamp 200 can be fixed to installation site (each lamp socket 1) thus.
Shown in Fig. 6 C, when movement parts 2 was in the closed position, the depth direction of the direction in the space from introducing port 42 to contact 30 and directional slit 800 intersected with 90 degree roughly.Here, the spacing of contact 30 is narrower than the spacing of two lamp bases 230, and therefore two lamp bases 230 that insert in the lamp foot jack 500 contact and are electrically connected with contact 30.In addition, two lamp bases 230 also correspondingly are coupled in the lamp base maintaining part 302 of two contacts 30 and by its maintenance.Because contact 30 is parts of conductive plate 3, therefore guarantee the contact pressure of 30 pairs of lamp bases 230 of contact by the elasticity of conductive plate 3.
In the first embodiment, when lamp 200 is in the installed position of lighting apparatus 250, with 2 rotations of each movement parts and move to off-position, thereby lamp 200 can be fixed in the installation site.Equally, with 2 rotations of each movement parts and move to open position, thereby lamp 200 can be removed from the installation site.At this, two pairs of lamp bases 230 correspondingly are present in the directional slit 800 of two supporting members 6, thereby lamp 200 is remained on the state that makes it move and not rotate with movement parts 2 along specific direction from the installation site.
Therefore, shown in the arrow A of Fig. 2, rotating motion part 2 can be fixed in the installation site of lighting apparatus 250 thus under the situation of revolving light 200 not.Similarly, along the opposite spin movement parts 2 of arrow A, can under the situation of revolving light 200 not, it be separated the installation site thus.Owing to need not revolving light 200,, still lamp 200 easily can be attached to the installation site or unload from the installation site even therefore around lamp 200, can't guarantee to rotate by hand the space of lamp 200.In traditional lamp socket, when attached or lamp removal, need revolving light, therefore for large-scale lamp, operability variation when attached or dismounting lamp.In the first embodiment, the size of lamp no matter only needs by the part 2 of doing exercises just can be easily that lamp is attached or dismantle.
As shown in Figure 3 and Figure 4, in the first embodiment, two bendable member 802 are correspondingly formed and are arranged in the both sides of axle 801 of the antetheca 80 of outer cover 8 by two U-shaped slits.The tip side of these two bendable member 802 is flexible, and from correspondingly outstanding backward two projections 803 in the top of two bendable member 802.On the other hand, the antetheca 50 of inner cover 5 is formed with a plurality of holes 501.In in each be coupled to hole 501 in two projections 803 any one.In the example of Fig. 3, a plurality of holes 501 comprise when movement parts 2 is shown in an open position projection 803 correspondingly be coupled to wherein two holes 501 and when movement parts 2 is in the closed position one of them projection 803 be coupled to wherein hole 501.When movement parts 2 was in the closed position, wherein another projection 803 was coupled in the open side of lamp foot jack 500.Yet, being not limited thereto, hole 501 can comprise that when movement parts 2 is in the closed position projection 803 correspondingly is coupled to two holes wherein.Therefore, if movement parts 2 is rotated from open position, then correspondingly 501 releases make two bendable member 802 bendings simultaneously from two holes with two projections 803.Therefore, if movement parts 2 moves to off-position, then two projections 803 correspondingly are coupled in the open side of hole 501 and lamp foot jack 500.Here, can access the engaging sense.Similarly, when also accessing engaging when off-position moves to open position, movement parts 2 feels.
Shown in Fig. 7 A and 7B, movement parts 2 comprises two jacks 40 that penetrate the bottom of interior body 4 along the direction of the axle (rotating shaft) of interior body 4.In this case, two of electric wire 400 lead 400a (crust is not shown) correspondingly insert in two jacks 40 along the direction of the rotating shaft of movement parts 2.Therefore, even movement parts 2 is rotated as being shown between the off-position shown in the open position shown in Fig. 7 A and Fig. 7 B by arrow A, still can reduce the crossing area C1 that electric wire 400 enters movement parts 2 relatively.That is, need not around two jacks 40, to guarantee that two lead 400a with electric wire 400 insert exceptional space wherein.
Shown in Fig. 5 A, the surface of introducing port 42 sides of lever 43 be with interior body 4 in the continuous flat surface of part spot face of introducing port 42.Therefore, when two lamp bases 230 inserted the lamp foot jack 500 from introducing port 42 sides along flat surface, lamp base 230 was guided by flat surface.Therefore, lamp base 230 easily can be inserted or extracts lamp foot jack 500.
As shown in Figure 2, the body 260 of lighting apparatus 250 is provided with the temporary transient keeper 270 that is used for lamp 200 is temporarily remained on the installation site.Temporary transient keeper 270 comprises two spring clips that for example formed by rubber-like sheet material respectively.Regardless of the position (open position and off-position) of movement parts 2, temporary transient keeper 270 all clamps and the temporary transient middle part that keeps lamp 200 at installed position.Two spring clips correspondingly have two arc-shaped depression portion 280 that face with each other, and each arc-shaped depression portion has the shape corresponding to the sidepiece of lamp 200.When movement parts 2 is shown in an open position, can remove lamp 200 by the curved top portion that spring clip is driven in expansion.For example, temporary transient keeper 270 can with supporting member 6 integrators.
Be provided with temporary transient keeper 270, regardless of the position of movement parts 2, can both temporarily keep lamp 200 thus at installed position.Therefore in this case, operative employee or user only need utilize lever 43 rotating motion part 2 and need not to rotate by hand lamp 200, can easily fix (locking) lamp 200 or with lamp 200 releases.In addition, when lamp 200 was discharged, promptly when movement parts 2 was shown in an open position, lamp base 230 did not contact with contact 30.
Except the lighting apparatus 250 of the straight pipe type fluorescent lamp that is used for Fig. 2, the lamp socket 1 in first execution mode also can be applicable to for example lighting apparatus 250 of the non-straight pipe type fluorescent lamp shown in Fig. 8 A and Fig. 8 B.The lamp 200 of the lighting apparatus 250 among Fig. 8 A and Fig. 8 B has two lamp holders 220, but from the projected direction separately of two pairs of outstanding lamp bases 230 of two lamp holders 220 not on identical straight line.That is, two lamp holders 220 are incorporated into the two ends of coupling connection part 240, make two pairs of lamp bases 230 outstanding along opposite directions.Therefore, the fluorescent tube (not shown) between the lamp holder 220 becomes non-straight pipe type.For example, fluorescent tube can have following shape, that is: two parts of extending from two lamp holders 220 in the counterclockwise direction helical buckling (for example 1 1/2 change) thus be bonded to each other in the centre of coupling connection part 240.The lighting apparatus 250 of Fig. 8 A and Fig. 8 B has discoid body 260, and two lamp sockets based on corresponding to the fixed-site of two lamp holders 220 in body 260.
In the lamp 200 of Fig. 8 A and Fig. 8 B, because the projected direction separately of two pairs of lamp bases 230 is on identical straight line, so lamp 200 can not the same central shaft rotation around fluorescent tube with the straight pipe type fluorescent lamp.For this reason, in the lighting apparatus of lamp socket, can not adopt the lamp 200 of Fig. 8 A and Fig. 8 B with Fig. 1.On the other hand, in the lighting apparatus of the lamp socket 1 with first execution mode, the lamp 200 of Fig. 8 A and Fig. 8 B need not to be rotated, and therefore can adopt lamp 200.That is, shown in Fig. 8 A, when each movement parts 2 is shown in an open position, lamp 200 can be placed the installed position of lighting apparatus 250.Here, as by the mode motion lamp 200 shown in the arrow B, make that two pairs of lamp bases 230 in the lamp 200 correspondingly insert in the lamp foot jack 500 of two lamp sockets 1.As by shown in the arrow A of Fig. 8 A, each movement parts 2 is moved to off-position, thus lamp 200 is fixed to the installation site, and finishes the attached of lamp 200 and electrical connection.
Therefore, in the lamp socket 1 of first execution mode, can under the situation of revolving light 200 not, carry out lamp 200 attached and remove.Therefore, even the projected direction separately of two pairs of lamp bases 230 not on identical straight line, still can be attached to lamp the installation site of lighting apparatus or unload from the installation site of lighting apparatus.And, owing to need not to be used for the space of revolving light, so the size that can dwindle lighting apparatus.
The lighting apparatus of Fig. 8 A and Fig. 8 B has temporary transient keeper 270, is used for temporarily keeping lamp 200 by being fixedly clamped at the lamp holder 220 at the two ends of coupling connection part 240.Thus, can there be load to be loaded into the temporary transient lamp 200 that keeps under the state of fluorescent tube.In addition,, therefore can adopt lamp 200, that is, be difficult to improve the glass lamp of intensity because of fluorescent tube and the complicated shape that attenuates with following glass lamp owing to there is not load to be loaded into fluorescent tube.
In one embodiment, outer cover 8 has the mechanism that is used to stop body 4 in conductive plate 3 disengagings.In this case, can save inner cover 5.In one embodiment, body 260 integrators of outer cover 8 and lighting apparatus 250.In another embodiment, supporting member 6 is formed by two members that separate along the length direction through directional slit.
Fig. 9 shows the lamp socket 1 according to second embodiment of the invention.Form the problem of this lamp socket 1 in order to the lamp socket that solves first execution mode.
Described problem at first is described, in the lighting apparatus of the lamp socket 1 with first execution mode, the movement parts 2 of rotary lampholder 2 under the state of revolving light 200 not can be attached to lamp 200 installation site of lighting apparatus thus.Similarly, lamp 200 can be unloaded from the installation site.This attached and disassembly mechanism is different from traditional mechanism fully, that is, make the rotation of straight pipe type fluorescent lamp and therefore the straight pipe type fluorescent lamp can be attached to the installation site of lighting apparatus or unload from the installation site of lighting apparatus.Therefore, in the first embodiment, after the installation site of the lighting apparatus that shown in Figure 10 A, lamp (straight pipe type fluorescent lamp) is placed, may carry out the faulty operation that attempting shown in Figure 10 B makes the lamp rotation.
For example, if the user carries out such faulty operation, then two pairs of lamp bases 230 in the lamp 200 correspondingly clash into the edge of two directional slits 800, and respectively to lamp base 230 and supporting member 6 imposed loads.Here, if the user continues revolving light 230, then lamp 230 or supporting member 6 can be damaged.For example, lamp base bending.Perhaps directional slit 800 is opened then by expansion outer cover 8 is destroyed.
The lamp socket of second execution mode has the attached and disassembly mechanism identical with first execution mode, and can prevent the lamp that caused by aforementioned faulty operation and the destruction of supporting member 6.
That is, the same with first execution mode, the lamp socket 1 of second execution mode is used for lighting apparatus is limited the installation site of lamp and will place the lamp of installed position to fix.Lamp socket 1 has movement parts 2 and supporting member 6 equally, and can give the lamp that is fixed on installed position energising.Supporting member 6 is different from the supporting member of first execution mode.Other structure is then identical with other structure of first execution mode and no longer describe in detail herein.
As shown in Figure 9, the outer cover 8 of supporting member 6 is formed with guide opening 804 but not directional slit 800 in first execution mode.This guide opening 804 is following shape,, is formed with two recessed cutout 805 in the both sides of the middle body of directional slit 800 that is.Two recessed cutout 805 form make when the straight pipe type fluorescent lamp that is in installed position when the axle of fluorescent tube rotates, the lamp base of two correspondences can correspondingly enter two recessed cutout 805.In brief, the difference of the supporting member 6 of second execution mode and first execution mode is also to be provided with two recessed cutout.In addition, the supporting member 6 of second execution mode does not have to be provided with the actual axle corresponding to axle 801 (see figure 4)s of first execution mode, but has center (rotation) axle that obtains from cylinder form.
In the example of Fig. 9, two recessed cutout 805 form and make the lamp that allows to be in installed position to revolve three-sixth turn along movement parts 2 directions of motion.Particularly, the top of guide opening 804 (800) width of having is narrower than the spacing of two lamp bases 230 and is a bit larger tham the diameter of each lamp base 230.Each recessed cutout 805 is the bandy shape of profile, and guide opening 804 has rounded portions thus.This rounded portions has corresponding to the center of the rotating shaft of movement parts 2 and its diameter spacing greater than two lamp bases.Shown in Fig. 9 waited, hereinafter, left recessed cutout and right recessed cutout were correspondingly pointed out by 805A and 805B.Shown in Figure 11 A,, directly the last lamp base of lamp after specific direction places the installation site and following lamp base are correspondingly pointed out by 230A and 230B in order to distinguish two lamp bases 230.
Shown in Figure 11 A, even in second execution mode, for lamp is placed the installed position of lighting apparatus along specific direction, movement parts 2 still must be shown in an open position.That is, when movement parts 2 is shown in an open position, lamp is moved along specific direction, then the depth direction of two pairs of lamp bases 230 along guide opening 804 is inserted into the lamp foot jack 500 from introducing port 42 sides.Subsequently, if make movement parts 2 move to off-position, then lamp can be fixed to the installation site, and can switch on to lamp by lever 43.
Yet even be not the axle rotation around fluorescent tube shown in the arrow A of Figure 11 A of movement parts 2 but lamp (straight pipe type fluorescent lamp), each in two lamp bases 230 also can correspondingly enter the recessed cutout 805 of two correspondences.Particularly, shown in Figure 11 B, lamp base 230A and 230B can correspondingly enter recessed cutout 805A and 805B.Therefore, even will be in of the axle rotation of the lamp of installation site, still can not produce big stress between outer cover 8 and each lamp base 230 around fluorescent tube.When moving to the position of Figure 11 B, lamp base 230A equally correspondingly contacts and is electrically connected with two contacts 30 with 230B.Here, lamp base 230A and 230B correspondingly cooperate and are fixed in two lamp base maintaining parts 302.In addition, because the top of guide opening 804 is narrower than the spacing of lamp base 230A and 230B, so lamp can't pass through this top.If lamp rotates in the direction of arrow A from the position of Figure 11 B, then lamp base 230A and 230B correspondingly move to the bottom side of guide opening 804 and top side and move to 1/2 position of changeing subsequently shown in Figure 11 C.Equally in this case, can not produce big stress between outer cover 8 and each lamp base 230.
Similarly, though lamp along the opposite spin of arrow A, two lamp bases 230 also can correspondingly enter the recessed cutout 805 of two correspondences respectively.That is, lamp base 230A and 230B can correspondingly enter recessed cutout 805B and 805A, and can not produce big stress between outer cover 8 and each lamp base 230.When lamp rotation roughly 90 when spending, lamp base 230A and 230B correspondingly cooperate and are fixed in two lamp base maintaining parts 302.Equally in this case, lamp can't be by the top of guide opening 804.When lamp during further along the opposite spin of arrow A, lamp base 230A and 230B correspondingly move to the bottom side of guide opening 804 and top side and move to 1/2 position of changeing subsequently.Equally in this case, can not produce big stress between outer cover 8 and each lamp base 230.
As shown in Figure 9, in second execution mode, two contacts 30 are arranged on guide opening 804 back relative to one another, make its spacing that has be wider than the top of guide opening 804.Therefore, the lamp base 230 that is in the position of Figure 11 A can not contact with two contacts 30 along guide opening 804 free movements.So, when movement parts 2 is in open position shown in Figure 11 A, can lamp be inserted the installation site of lighting apparatus or unloads along specific direction from the installation site of lighting apparatus.At length say,, two lamp bases 230 804 are inserted the lamp foot jacks 500 from introducing port 42 sides along guide opening respectively when when specific direction places the installation site with lamp.The movement parts 2 that will be in the position of Figure 11 A then moves to off-position, thus 30 rotations of two contacts roughly 90 degree correspondingly to contact with two lamp bases 230 of the position that is in Figure 11 A.Here, utilize movement parts 2 to close, make two lamp bases 230 are fixed in the installation site thereby introducing port 42 also rotates roughly the top that 90 degree leave guide opening 804 and guide opening 804.Therefore, the same with first execution mode, can under the situation of revolving light not, be fixed in the installation site, can switch on to lamp simultaneously.
In addition, even be in the lamp rotation of the position of Figure 11 A, two lamp bases 230 also can correspondingly enter the recessed cutout 805 of two correspondences, therefore can not produce big stress between outer cover 8 and each lamp base 230.Thus, when attached or lamp removal, can prevent the lamp that causes because of faulty operation and the destruction of supporting member 6.Therefore, in the lighting apparatus 250 of lamp socket 1, can the same with first execution mode lamp be attached to the installation site or unload from the installation site with second execution mode.And, when attached or lamp removal, can prevent the lamp that causes because of faulty operation and the destruction of supporting member 6.
In one embodiment, one of them in 10 alternative two lamp sockets 1 of the lamp socket shown in employing Figure 12 A, 12B, 13A and the 13B.Lamp socket 10 comprises the housing 11 that is fixed in the lighting apparatus body.Housing 11 has lamp foot jack 130, places two lamp bases of lamp of the installed position of lighting apparatus to insert this lamp foot jack.
Also be provided with two conductive plates 3 positioned opposite to each other of similar lamp socket 1 in this housing 11, thus but two roughly 90 degree laterally settings shown in Figure 12 A of conductive plate 3 rotations.Two contacts 30 and two terminals 31 place housing 11 equally and correspondingly are arranged on the front and rear of housing 11.
Shown in Figure 12 B, housing 11 is formed by body 12 and cover 13.Body 12 and cover 13 are respectively the synthetic resin moulded parts of being made by the resin material that is used to insulate.Cover 13 is attached to the front portion of body 12, is equipped with two conductive plates 3 in the body.
Shown in Figure 12 A, in lamp socket 10, two conductive plates 3 place housing 11, make that two contacts 30 are positioned opposite to each other.Therefore, as shown in FIG. 13A, two lamp bases 230 insert in the housing 11 by lamp foot jack 130.That is, two lamp bases 230 insert between two contacts 30 then along the length direction setting of each contact 30.Lamp is followed the usual practice as the central shaft rotation of direction (clockwise direction) the lamp foot winding jack 130 of arrow C.Subsequently, two lamp bases 230 correspondingly are coupled in two lamp base maintaining parts 302, the side end with lamp is fixed in lamp socket 10 thus.
The lighting apparatus of this execution mode is provided with the lamp socket 10 and the lamp socket 1 of second execution mode for example.The attached of 200 pairs of these lighting apparatus of lamp now is described.At first, the movement parts 2 with lamp socket 1 is set in open position.Then as shown in FIG. 13A, two lamp bases 230 with a lamp holder of lamp insert in the housings 11 by lamp foot jack 130.Subsequently, make the central shaft rotation of lamp 200 lamp foot winding jacks 130, and two lamp bases 230 of another lamp holder 804 are inserted the lamp foot jacks 500 from introducing port 42 sides along guide opening.At last, movement parts 2 is rotated to off-position from open position.
Like this, adopted lamp socket 1 and lamp socket 10, the number of times of operational movement part 2 can be reduced to once thus.Therefore, lamp easily can be attached to the installation site of lighting apparatus and unloading from the installation site of lighting apparatus equally.When lamp places installed position, need not revolving light, even thereby the narrow and small lamp that still can easily fixedly place installed position in space around the lamp.Compare with the lamp socket 1 of second execution mode, lamp socket is 10 simple in structure, number of components is few and low cost of manufacture, therefore can reduce the manufacturing cost of whole lighting apparatus.
Each lamp socket 1 of first execution mode and second execution mode is not limited to above-mentioned example, but can retrofit under the situation that does not deviate from spirit of the present invention.Equally, lamp socket 1 also is not limited to the lighting apparatus 250 that is used for the lamp 200 shown in Fig. 8 A and Fig. 8 B.For example, lamp socket 1 can also be used for following lighting apparatus, promptly is used for the lighting apparatus of straight pipe type fluorescent lamp shown in Figure 2 etc., and is not limited to the lighting apparatus of particular types.The lamp socket 10 of Figure 12 A can combine with any lamp socket that is different from lamp socket 10 but is not limited to the lamp socket 1 of second execution mode.
Figure 14 shows the lamp socket 1 according to third embodiment of the invention.Except two recessed cutout 805 of the 3rd execution mode separately shape be different from the shape of recessed cutout of second execution mode, this lamp socket 1 forms in the mode identical with second execution mode.Therefore, be not described in detail the structure identical at this with second execution mode.
As shown in figure 14, two of the 3rd execution mode recessed cutout 805 form and make that the lamp (for example, straight pipe type fluorescent lamp) of the installed position that places lighting apparatus can be along the direction of motion rotation of movement parts 2 90 degree roughly.In the example of Figure 14, two recessed cutout 805 form and make lamp (counterclockwise) rotation 90 degree roughly in the direction of arrow A.
Particularly, it is fan-shaped that two recessed cutout 805 correspondingly form, and it has the central angles of 90 degree roughly respectively and is symmetrical arranged about the center corresponding to the circle of outer cover 8 profiles.In addition, the distance (diameter) between two of two recessed cutout 805 arc portions is set the spacing of its size greater than two lamp bases 230 for.
In the 3rd execution mode, shown in Figure 15 A, when movement parts 2 was shown in an open position, two lamp bases 230 were along the depth direction setting of guide opening 804, and inserted lamp foot jack 500 along this depth direction from introducing port 42 sides.Here, lamp almost can not turn clockwise, but (counterclockwise) rotation in the direction of arrow A.And shown in Figure 15 B, even lamp is rotated counterclockwise, lamp base 230A and 230B also can correspondingly enter two recessed cutout 805A and 805B.Therefore, lamp roughly revolve turn 90 degrees before, can not produce big stress between outer cover 8 and each lamp base 230.When rotating to the position of Figure 15 B, two lamp bases 230 are coupled in two lamp base maintaining parts 302, thereby correspondingly are electrically connected with two contacts 30.The top of guide opening 804 is narrower than the spacing of two lamp bases 230 equally, so lamp can't pass through top.
Compare with the recessed cutout of second execution mode, can dwindle each recessed cutout 805 of the 3rd execution mode.Correspondingly, the movement parts 2 with contact 30 can preferably place as lower supporting part 6, wherein is formed with the guide opening 804 with less recessed cutout 805.Lamp can also rotate roughly 90 degree around the axle of fluorescent tube, so the user can notice operating mistake or recognize that lamp is fully rotated.Therefore, the lamp socket in the 3rd execution mode can have the recessed cutout that has 805 that almost is equal to second execution mode and forms and make lamp to rotate to surpass the performance (for example, can prevent the ability that lamp socket and each lamp base destroy) of the lamp sockets of 90 degree.And, can under the situation of revolving light not, secure it to the installation site, can switch on to lamp simultaneously.
In alternative exemplary, two recessed cutout form and make lamp can be rotated in a clockwise direction roughly 90 degree.Yet, being not limited to 90 degree, each recessed cutout can be for having the shape as lower angle,, makes the angle that two lamp bases 230 can correspondingly contact with two contacts 30 that is.This shape can according to circumstances change.
Figure 16 shows the lamp socket 1 according to four embodiment of the invention.Except that the shape of the guide opening 804 of outer cover 8 was different from the shape of guide opening of the 3rd execution mode, this lamp socket 1 formed in the mode identical with the 3rd execution mode.Therefore, do not describing the structure identical in detail at this with the 3rd execution mode.
Shown in Figure 16,17A-17C and 18A-18C, the guide opening 804 in the 4th execution mode has and forms two recessed cutout 805 that are similar to the 3rd execution mode and be bonded to one of them guide slits 806 in two recessed cutout 805.This guide slits 806 be bonded to when lamp in the direction of arrow A (counterclockwise) when rotation the recessed cutout 805A that enters of lamp base 230A.In addition, guide slits 806 forms and makes and to guide the top side of lamp base 230B towards opening 804 simultaneously when the lamp rotation enters guide slits 806 above 90 230A of lamp base when spending roughly from recessed cutout 805A.
Particularly, guide slits 806 is a semicircular in shape, its from corresponding to lamp base maintaining part 302 sides (referring to Fig. 9) of the lamp base 230A the recessed cutout 805A outwards (among Figure 17 C towards left to) extend.The diameter of semicircle guide slits 806 is set the value of the diameter that is slightly larger than each lamp base 230 for.Shown in Figure 17 C and Figure 18 A, guide slits 806 extends into and makes contact 30 be pushed by lamp base 230A and crooked and lamp base 230A can be to left movement thus, and lamp base 230B can be from recessed cutout 805B to the motion of the top of guide opening 804 simultaneously.Therefore, the boundary between recessed cutout 805B and the top is the shape on circular arch surface.
In the 4th execution mode, shown in Figure 17 A, when movement parts 2 was shown in an open position, two lamp bases 230 inserted the lamp foot jack 500 along this depth direction along the depth direction setting of guide opening 804 and from introducing port 42 sides.Here, lamp almost can not turn clockwise, but (counterclockwise) rotation in the direction of arrow A.And shown in Figure 17 B, even lamp is rotated counterclockwise, lamp base 230A and 230B also can correspondingly enter two recessed cutout 805A and 805B.Therefore, roughly before 90 degree, can not produce big stress between outer cover 8 and each lamp base 230 in lamp rotation.If lamp rotates to the position of Figure 17 C, then two lamp bases 230 correspondingly are coupled in two lamp base maintaining parts 302 and also are electrically connected with two contacts 30 thus.Equally, the top of guide opening 804 is narrower than the spacing of two lamp bases 230, so lamp can't pass through top.
Subsequently, when lamp further when being rotated counterclockwise, lamp base 230B touches recessed cutout 805B, thus lamp base 230A extruding contact 30 and make contact 30 crooked and enter guide slits 806 to left movement then thus.Then, lamp base 230B crosses the boundary between recessed cutout 805B and guide opening 804 tops, and shifts to guide opening 804 (Figure 17 C and 18A-18B) then.After this, shown in Figure 18 C, can two lamp bases 230 be extracted guide opening 804 via introducing port 42.
In the 4th execution mode, guide opening 804 only is provided with a guide slits 806, and lamp can rotate and surpass 90 degree thus.Therefore, compare, can advantageously prevent the destruction of lamp and supporting member 6 with the 3rd execution mode.Because guide opening 804 only is provided with a guide slits 806, the area that therefore can suppress guide opening 804 increases.And, can under the situation of revolving light not, secure it to the installation site, can switch on to lamp simultaneously.
Although described the present invention with reference to some preferred implementation, those skilled in the art can make multiple remodeling and variant under the situation that does not deviate from connotation of the present invention and scope.
