The field of the invention

The present invention relates to a kind of fitting structure that high illuminance can be provided by desired direction with regard to its all aspect, especially (but not only) is relevant with high-pressure discharge lamp or incandescent lamp.

Prior art

The patent No. is that the special US Patent specification that must woods (Ptchelin) of 5,041,755 pool has been set forth a kind of light fixture that has the glass cell-shell of long and projection, and the cross section of this glass cell-shell is non-circular, and is adorning a terminals connector at the one end.Luminescence component in the light fixture is equipped with the intense light source like bar-like shape, and it is along the optical axis longitudinal extension that gives the light fixture of setting earlier.This light fixture cell-shell upper surface within it divides the ground coated high reflectivity layer or reflectance coating.Cell-shell can be evacuated, also can be filled with a kind of inert gas.When using this light fixture, the light that optical axis produced from cell-shell not the surperficial formed transparent window of coated transmit, part light is directly from light source, part light is then because the result of the reflection of the reflectance coating in cell-shell but not directly transmission.The profile of light fixture inner surface should be got such shape, promptly passes through along the path of penetrating basically less than optical axis owing to its shape makes the light that is reflected, because this optical wand and optical axis are arranged in delegation, thereby this optical wand does not subject to excessive heat.This was prolonged with regard to the life-span that makes optical wand.A kind of light fixture like this will be referred to as the light fixture of " having described type " hereinafter.

The radiative pattern that light fixture produced with described type relates to the stability of its quality and is launched model shape, and these are all determined by the accuracy that the member of the luminescence component in the light fixture cell-shell is located.When light fixture is installed in the lighting apparatus of having located, for example, when lighting apparatus is arranged on the top, street of wanting illuminated, shine the quality and the stability of the optical mode on the street, not only depend on the location of luminescence component in light fixture, and depend on the angle location of the socket that is provided with for installation light fixture in lighting apparatus.

Purpose of the present invention

The objective of the invention is for a kind of light fixture that has improved is provided.The present invention's summary

According to primary goal of the present invention, the directed light fixture of a kind of high illuminance, it has attached to the terminals connector on the glass cell-shell, the inner sleeve and the outer sleeve that connect with electrical interconnect that this terminals connector comprises arranged coaxial, inner sleeve and outer sleeve can relative the rotations between mutually and do not have axial relative displacement, the terminals connector also comprises and is used to limit outer sleeve with the retaining device of a certain direction with respect to the inner sleeve rotation, and one the source takes place and is arranged between the binding post of two mutual insulatings on the terminals connector electric installation that is electrically connected is provided at light, and this light generation source forms the parts of the luminescence component in this light fixture; In this light fixture, said retaining device comprises an one-way ratchet, and it makes outer sleeve can unrestrictedly rotate relatively by a certain direction with respect to inner sleeve, but when outer sleeve rotated with respect to inner sleeve in the opposite direction, detent mechanism limited its rotation.

The light fixture of above-mentioned structure is compared with the light fixture of prior art structure has many advantages.For example, this one-way ratchet allows this light fixture to be screwed into its socket in lighting apparatus, and then, by means of the lasting rotation of light fixture with equidirectional, the light-emitting mode of light fixture can be transferred to desired angle position.This can realize and the risk that do not have the terminals connector to be back-outed a little from its service position, otherwise, will make electrically contacting off and between light fixture and socket, and in socket, rock.There is not obstacle in light fixture because of detent mechanism under the dismounting from socket, because it only allows outer sleeve unrestrictedly to rotate with a certain direction with respect to inner sleeve.If will back out light fixture from socket, as long as rotate light fixture in the opposite direction, this detent mechanism will play as same supporting the effect thing or the retaining device, so these two sleeves will rotate in the opposite direction together and back out light fixture.

According to secondly target of the present invention, the present invention also comprises: the light fixture with described type, it comprises that one has the glass cell-shell of reflectance coating and holding an optical wand that forms the parts of luminescence component, this luminescence component makes optical wand and the optical axis that gives the light fixture of setting earlier be arranged in delegation, said optical wand one end is by being supported attached to the terminals connector on cell-shell one end, its other end is supported by a retainer, this retainer is meshed with the drip molding of the glass cell-shell other end that is arranged on terminals connector offside, this luminescence component comprise make optical wand two ends respectively with the terminals connector on two electric conductors that binding post is connected, said electric conductor comprises that one of position between the reflectance coating that is on optical wand and the cell-shell is traversed line, it one of two binding posts and optical wand away from an end of terminals connector between conduction current; In this light fixture, this drip molding has non-circular cross sections, this retainer has the shape of cross section with the cross section complementation of this drip molding, and with the combination of this and drip molding, give on the angle position of setting earlier thereby this is traversed one that line remains on respect to optical axis,, project the heat that traverses on the line and minimize degree in this position, the structure of this retainer has from the centering function it, so that the abutting end of optical wand is remained on the desirable optical axis.

The advantage of a second aspect of the present invention is, by the reliable engagement of retainer and molded part, this traverses line can automatically be positioned its correct angle position, and such engagement has guaranteed that also the approach end of optical wand is properly positioned on the optical axis.

Have been found that, if traverse the two ends of line is not all to be supported on effectively the position should be arranged, then in assembling light fixture process and after the light fixture assembling, the direction of traversing line can change, and this can cause the pattern generation deviation of light and reduce the luminous flux that light fixture sends.But in the light fixture of constructing, the problems referred to above can not occur, be fixed on the terminals connector because traverse an end of line according to second target of the present invention, the other end that traverses line owing to retainer with respect to the reliable configuration of the drip molding location that is fixed.Optimization feature of the present invention

This drip molding can adopt the socket with non-circular cross sections or the form of socket.But more preferably, drip molding is constructed to have an alcove of triangular cross section, and it is positioned at an end relative with the terminals socket of glass cell-shell.A kind of like this advantage of configuration is that retainer is properly positioned in the alcove on the desirable position.The outer surface of alcove can be used to light fixture is fixed on the position in the lighting apparatus, thereby makes light fixture be maintained at this position and the moving of the rotation avoiding taking place afterwards or end, for example, this rotation or end move may since vibrations or impact produce.Adorning the cup of a formation recipient part in the light fixture aptly, it makes the position that will be in specific axial and rotation by the light fixture that alcove is supported.In the process that light fixture is contained in the lighting apparatus, this recipient can be thrown off, so light fixture can rotate until finding its optimum position.Cup can mesh with the outer surface of alcove then, so that this recipient can clamp light fixture and prevent that in its working life process it from rotating and move the end.On the recipient compression spring can be housed, be firmly held on its service position in lighting apparatus to impel light fixture.

Most preferred embodiment is set forth

Fig. 1 has shown an inflation Discharging lamps and lanterns 1 that has non-circular globular glass cell-shell 2, and this cell-shell 2 provides the transparent bottom surface of convex 3 for light fixture 1.The multiple arch bubble top 4 of projection is arranged at the top of cell-shell 2, and as shown in Figure 2, the inside on bubble top 4 is covered by metal coat reflectance coating 5.The lower limb 6 of film 5 is arranged in the horizontal plane of the optics longitudinal axis 7 below partition distance of lamp 1.Each vault intersects along straight line in respect to axle 7 respective planes radially each other.Vault should be got such shape, i.e. light and heat that optical wand 8 on the optical axis 7 that is positioned at light fixture 1 produced owing to its shape, can reflect from film 5 towards the below less than the direction of optical wand 8 by radiation, thereby the heat drop of penetrating from film 5 that optical wand 8 is suffered is extremely minimum.

Light fixture 1 has a terminals connector that is made of terminal block 9, and terminal block 9 has Edison (Edison) spiral matrix 100.This matrix 100 has 11 and one of center terminal makes terminal 11 and the conical insulator 13 of the frustum of external spiral terminal 12 insulation.

More detailed in Fig. 3,6 and 7 is the structure that has shown terminals connector section 9.Spiral terminal 12 provides the outer metal sleeve 14 of external screw thread line to form by one, it contacts with cylindrical shape inner sleeve 15 and can rotate around inner sleeve 15, so that can both keep good electrical contact between these two sleeves when outer sleeve 14 is in any angle position with respect to inner sleeve 15.The glass cell-shell has the neck 50 of individual reduced in its terminal, and it has been in sealed on the glass mandrel 21 (partly having shown this structure) in Fig. 1 and Fig. 3, and is parallel to wire electrode 23 and 24 by mandrel 21 and extends.Only shown electrode wires 23 among Fig. 3.Electrode wires 23 is connected on the center of light fixture terminals column bolt end 58 by guide rod 56.Another root electrode wires 24 (see figure 3)s contact with the inwall of inner sleeve 15 at label 59 places.Bonding charges 51 adhere to inner sleeve 15 on the outer wall of glass neck 50.As shown in the figure, the conical insulator 13 of frustum is also adhered on the inwall of inner sleeve 15, and insulator 13 also has a centre bore 57, and guide rod 56 extends to stud terminal 58 and welding or soldering thereon by centre bore 57.

Hang rod 55 and insulation axle center 56 (line 32 extends by this axle center), before assembly 35 is connected to line 23,24, form the component part of assembly 35.

Sleeve 14 with 15 formed parallel radial flange 17 and 52 (shown in Figure 7) away from the inside turnup of adjacent edge acies of neck 50.They are in the groove of the ring 18 with outside chamber shape cross section.The groove that the metal washer 19 of a ring-type also is arranged in ring 18 to be increasing frictional force, is pressed together on together thereby guarantees to have contacting of good electric and machinery by means of these two flanges 15 and 17 of this frictional force between them.Insufficient pressure between flange is rotated on inner sleeve 15 to stop outer sleeve 14, but is enough to make such rotation need overcome stable frictional resistance.Though Fig. 3 demonstrates flange 17 and 52 a little gap is arranged, in fact do not exist such gap, ring 18 then to play a part to prevent axial motion between the sleeve 14,15.

Fig. 7 has shown sleeve 14,15 and ring 18 are how to fit together and form a subunit.

Shown in the following position of Fig. 7, ring 18 initial shape are for to have the cylinder of a radial flange 16 at it than the lower end.Outer sleeve 14 is positioned on the cylinder so that on the flange 16 of the flange 17 of its inside turnup under being placed on.Inner sleeve 15 is inserted into that the flange 52 until its inside turnup is placed on the flange 17 in the sleeve 14.Metal washer 19 is assembled on the cylinder then, to be placed on the flange 52.Make then cylinder than the upper part outwards and distortion downwards with form one for ring 18 than upper flange 16 so that the flange 52 and 17 of sleeve, and packing ring 19, all be clipped in securely between two flanges 16 of ring.Again the conical insulator of the frustum 13 past the insides of transferring to inner sleeve 15, so that it passes ring 18 than the lower end.Then insulator 13 is bonded on ring 18 and the inner sleeve 15, has just finished in this subunit that label 51 places are bonded on the neck 50.

As shown in Figure 6, inner sleeve 15 is forming an outward extending sideling resilient fingers 20 towards it than the top edge end.Than upper marginal end portion a resilient fingers that extends internally 10 is set similarly also at outer sleeve 14, finger piece 10 is in such position, promptly when outer sleeve 14 with Fig. 6 in during the clockwise direction rotation, finger piece 10 can be to propping up resilient fingers 20 in this position.Because inner sleeve is adhered on the light fixture neck 50 at label 51 places, after supporting the position that takes place, outer sleeve 14 is rotated in a clockwise direction above this.On the other hand, as outer sleeve 14 is rotated with the counter-clockwise direction in Fig. 6, two resilient fingers 10 and 20 deflection make these two finger pieces can cross ratchet mutually, with activation outer sleeve 14 are unrestrictedly rotated with counter-clockwise direction.In this way, when making outer sleeve surpass a certain amount with a direction rotation, these two sleeves have just been blocked mutually, otherwise, rotation with other direction can infinitely continue, and is meanwhile keeping good electric and Mechanical Contact between two sleeves 14 and 15.

Get back to Fig. 1, a light generating assembly 25 is positioned at the inside of cell-shell 2, by being fixed on two electrode wires 23,24 on the mandrel 21, light generating assembly 25 is supported on the tail end of lamp.Light generating assembly 25 comprises the light source that an optical wand 8 that is extended by the optical axis 7 along light fixture constitutes.Optical wand 8 is equipped with two axially extended

metal electrode pipes

28 and 29 that stretch out from its two ends.By rigid support line 32 and U-shaped card 54 pipe 28 is connected on the wire electrode 23.Traversing line 36 by rigid support line 31 and arch is connected to pipe 29 on the electrode wires 24.

Can see significantly two

metal tubes

28 and 29 modes that are connected with 32 with their related Support Level 31 from Fig. 4, only show among Fig. 4 and connected modes that pipe 29 is related.But it also is same being interpreted as with managing 28 related modes.Fig. 1 is what to have simplified, in the figure, has omitted and some part and the parts in circle " A " that pipe 29 is related from economizing the figure of the pipe 28 of optical wand 8 other ends.

As shown in Figure 4, metal tube 29 has contained a bellend 30 of the rigid support line 31 that stretches out from the end of this pipe.Article one, have very strong elastic metallic band 33 twining partially to manage 29 and association line 31, the end of band 33 is welded on pipe 29 and the line 31 by point.Band 33 plays a part as very strong spring, and when assembly axially inserted the cell-shell of lamp, band 33 can absorb some and be applied to compression thrust on the assembly, consequently can cause good electric and mechanical connection all the time between pipe 29 and line 31.With this version, be restricted in the axial motion of the bellend 30 of pipe in 29, so that the assembling of lamp becomes easier, and the axial motion of the various parts that produce owing to thermal expansion and contraction also can be conditioned.

Traverse line 36 by means of arch, Support Level 31 is able to be electrically connected with electrode wires 24, traverses line 36 and passes through at the intersecting lens place near two vaults.To traverse line 36 very near from reflectance coating though schematic diagram 2 demonstrates, and in fact has spacing as between clearly showing among Fig. 1.

Support Level 31 extends to a retainer from metal tube, as shown in the reference numeral 35.This retainer has comprised three resilient U-shaped spares 37,38 and 39, and these three U-shaped spares are arranged in the plane of 120 ° of mutual displacements, knows three that show as Fig. 5.The adjacent arms limb of U-shaped spare is rigidly secured to the petiolarea of line 31, so that the outer arm limb of U-shaped spare mutually substantially abreast but the axis of pin deviated line 31 and extending.As shown in Figure 1, the joint of the outer arm limb of U-shaped line and position, intermediate portion arm limb is a fillet.

Petiolarea away from the glass cell-shell 2 of terminals termination environment 9 is equipped with alcove 22, and alcove 22 has usually as Fig. 2 and triangular cross section shown in Figure 5.Alcove and glass cell-shell 2 when it is made by whole casting together.See that as from Fig. 5, knowing when light generation component 25 was positioned at service position shown in Figure 1, U-shaped spare 37,38 and 39 outer arm limb were close to the corner of alcove.Holding the last turning of this alcove of U-shaped spare 37, as traversing the line 36, be arranged in the same sagittal plane of the optical axis 7 of lamp, making arch traverse line 36 effect of correct location automatically so the placement of the retainer 35 in the alcove 22 can be played.Simultaneously, the end of the optical wand 8 of contiguous alcove 22 correctly is positioned on the optical axis 7, because three U-shaped spares 37,38 and 39 similarly and configuration symmetrically, so they are when being inserted in the alcove, thereby they have just had from centering usefulness line 31 is remained on the optical axis 7.

Fig. 8 has shown the lamp among Fig. 1 is how to be assembled in the lighting apparatus 42, and lighting apparatus 42 is equipped with a female socket 43 that is used to accept the terminals section 9 of lamp.Lighting apparatus 42 has a major axis 44, and it axially extends through socket 43 and passes the conduit 48 that is positioned at the lighting apparatus other end.One rotatable and can extend through conduit 48 by axially movable bar 60 alive, and the end in it is in lighting apparatus has a triangle cup-shaped components 47.A spiral compression spring 49 forces cup-shaped components 47 to leave conduit 48.The size of cup-shaped components 47 will be adapted to be mounted within on the lateral wall of triangle alcove 22 of lamp 1.Bar 60, spring 49 and the cup-shaped components 47 of living forms such structure, a recipient 46 promptly is set, it can remain on its axle 44 that moves any desirable angle position alcove 22, and recipient 46 can prevent in a very long time that also lamp 1 from tilting in socket 43.The resilience of spring 49 also can be withstood the lamp 1 that causes the outwards motion from socket 43 by vibration or collision.

The assembling of most preferred embodiment and use

The assembling and the use of lamp shown in Figure 1 are described below:

Comprise optical wand 8, with band 33

Support Level

31,32 together, retainer 35 and traverse line 36 at interior assembly 25 is constructed to it and traverses line 36 and be in the axle and U-shaped spare 37 residing same planes with optical wand 8.By means of U-shaped card 54, this assembly 25 is by electrically and be mechanically connected on the nonflexible line 23,24 that stretches out from mandrel 21.

The glass cell-shell is given making has a plurality of vaults and alcove 22, and wall is coated with reflectance coating 5 within it.Originally the other end at the cell-shell 2 on alcove 22 opposites is opened, so that make the assembly made 25 of frame on mandrel 21 be able to axially be advanced in the cell-shell 2.During this action, the U-shaped spare 37,38 of retainer 35 and three outer arm limbs of 39, the axial advance motion by mandrel 21 is located in the alcove 22, and is complementary with the respective corners of alcove 22.This just puts into its position location at the alcove turning to the outer arm limb of U-shaped spare 37,38 and 39 definitely, and in this position, they are fixed by the natural resilience of U-shaped spare 37,38 and 39 then.Mechanical connection between rigid member 37,38 and the

metal tube

28,29 and the resilience force that produces, making has enough effective push to act on the assembly 25, thereby U-shaped spare 37,38 and 39 is sprung into the position shown in Fig. 1 and 5.

The position of the retainer 35 in the alcove plays two important function in assembling process, the first makes alcove with respect to the vault of cell-shell 2 accurate angle location be arranged during making alcove; It two is during making assembly 25, makes U-shaped spare 37,38 and 39 with respect to line 31 with traverse line 36 accurate angle location is arranged.When retainer 35 being pushed its phase of giving in alcove 22 during the service position, it has Support Level 31 and a kind ofly automatically acts on from centering, to cause optical axis 7 centerings of line 31 and cell-shell, meanwhile, also take it to and give the phase service position traversing line 36, in this position, traverse line 36 and be positioned at intersecting lens partition distance place with two central vaults of cell-shell, and thereunder.

In case retainer 35 is located in alcove 22, the position of mandrel 21 is just fixing, and the opening end that heats cell-shell 2 then makes it softening, and it is pressed on the mandrel 21, the two is merged and forms the hermetic seal state.

Then, by way of mandrel 21,, with glass cell-shell 2 or be evacuated to low pressure, perhaps charge into the pressure of inert gas to the phase of giving in common mode.By sleeve 14,15, ring 18, metal gas ket 19, peace conical butt insulator 13 is constituted gives module units, put into position shown in Figure 3 then, and online 24 and the metallic interior surface of sleeve 15 between, and online 23 and center terminal 11 between form and be electrically connected.With adhesive 51 sleeve 15 is sealed to neck 50 places of cell-shell 2 then.

In the lamp that assembles, two sleeves 14 and 15 can not relatively move mutually, but sleeve 14 can overcome the frictional force degree that produces between the contact-making surface of itself and sleeve 15 and around sleeve 15 rotations, this frictional force is enough to make cell-shell 2 to remain on any position that it rotates to respect to sleeve 14.As what mentioned in the past because finger piece 10 and 20 to supporting, only allow sleeve 14 with respect to sleeve 15 in a clockwise direction (as seen in fig. 6) do limited rotation.But its reverse rotation then can be ad infinitum lasting, because these two finger pieces can easily cross mutually when their each joints, thereby provides the single channel detent mechanism.

Fig. 8 and 9 has described light fixture has been assembled to method in the lighting apparatus.Lamp 1 is screwed in the socket 43 that is assembled to lighting apparatus 42 with customary way, that is to say by the direction that outer sleeve 14 is screwed into the internal thread socket of lighting apparatus and manually rotates this light fixture.The inhour rotation of this and Fig. 6 middle sleeve 14 adapts, and friction stability has guaranteed that the rotation of cell-shell 2 causes the corresponding rotation of outer sleeve 14 between two sleeves 14 and 15.Rotating once finishing of this lamp that produces when lamp fully is screwed into socket, bulb shell 2 also continues by same direction rotation, up to being considered to be suitable for making lamp that any position of needed optical mode is provided by the downside of lighting apparatus.

When the tram of bulb shell was found, cup-shaped components 47 turned to until itself and alcove 22 and is complementary, and it is trapped in alcove 22 within its triangle vallecular cavity then, and by the pressure of spring 49 alcove 22 was remained on its due position.The constraint of recipient 46 remains on cup-shaped components 47 and gives the phase position, thereby prevents bulb shell 2 later axial motion and rotatablely moving in lighting apparatus.

If want from lighting apparatus, to unload light fixture, can be by at first removing the constraint of 22 of cup-shaped components 47 and alcoves, then so that the direction hand rotation cell-shell 2 that inner sleeve 15 is rotated counterclockwise among Fig. 6.This just makes finger piece 20 enter into 10 pairs of states that support of finger piece with outer sleeve 14, and therefore, these two sleeves as one man unload light fixture with the direction of unscrewing screw.

The light fixture of constructing according to the embodiment of above elaboration has following running parameter and size:

150 watts of lamp powers

100 volts of light fixture voltages

Lamp current 1.8 peaces

Luminous flux 14 kilolumens

Illuminance 700 candle lights/1000 lumens in the time of 68 °

250 millimeters of the total lengths of light fixture

95 millimeters of the maximum gauges of light fixture cell-shell

The remodeling of 50 millimeters preferred embodiments of height of reflectance coating

Above-mentioned light fixture might have various remodeling.

For example, alcove 22 cross sections can have and not be leg-of-mutton other shape, for example, it can be a square or polygonal, so that the turning is provided the flexible arm limb of the retainer with the shape that conforms to it can be placed in these turnings, can be maintained on the desired position thereby make optical axis and traverse line.

Away from the terminals place alcove is set though be preferably in the bulb shell, the present invention is equal to available one and is complementary at inwardly outstanding fork coupling on the cell-shell and socket coupling on sub-assembly.For example, glass fork with inside sensing of polygonal cross section can be set on the bulb shell, and a jack connetor with complementary shape can be provided on the assembly of lamp, in assembling light fixture process, this plug in device coupling is meshed with fork.
