Below, about the detailed content of framework 50 with described feature, illustrate with Fig. 4 ~ Fig. 9.

[detailed content of framework]

Fig. 4 is the exploded perspective view of the framework 50 that embodiment relates to.

Fig. 5 A is the bottom view of the first cylindrical shell 60 that embodiment relates to.Fig. 5 B is the bottom view of the second cylindrical shell 70 that embodiment relates to.Specifically, Fig. 5 A and Fig. 5 B represents the profile of the first cylindrical shell 60 when seeing from the below of Fig. 4 (minus side of Z axis, lower with) and the second cylindrical shell 70.

Fig. 6 is the oblique view of the abutting part 63 of the first cylindrical shell 60 that relates to of embodiment and the profile of anti-delinking part 64.Specifically, in figure 6 in order to clearly represent abutting part 62 and anti-delinking part 64, the state the first cylindrical shell 60 being axially cut to roughly half is illustrated.

Fig. 7 is the bottom view of the framework 50 that embodiment relates to.Specifically, Fig. 7 illustrates when the below of Fig. 4 is seen, is combined with the profile of the framework 50 of the state of the first cylindrical shell 60 and the second cylindrical shell 70.

Fig. 8 is the oblique view of the inside of the framework 50 represented under the state that the first cylindrical shell 60 and the second cylindrical shell 70 combined.Specifically, state framework 50 being axially cut to roughly half is illustrated in fig. 8.

As shown in Figure 4, the second cylindrical shell 70 inserts from the opening not configuring the side of anti-delinking part 64 of the first cylindrical shell 60.

As shown in Figure 5A, the first cylindrical shell 60 has minor diameter part 61, and minor diameter part 61 has a pair abutting part 62, and this abutting part is configured on the opposed position in the inner surface of the cylindrical shell of internal diameter D1.The internal diameter Ds formed by these abutting parts 62 is less than the maximum outside diameter of the second cylindrical shell 70.

Specifically, as shown in Figure 5 B, the second cylindrical shell 70 has large-diameter portion 71, and large-diameter portion 71 has and is configured in a pair protuberance 72 that external diameter is the periphery of D2 (D2<D1).Defined the maximum outside diameter Dx of the second cylindrical shell 70 by these protuberances 72, the internal diameter Ds of the first cylindrical shell 60 is less than the maximum outside diameter Dx of the second cylindrical shell 70.

In addition, in present embodiment, minor diameter part 61, has the fitting portion 62a chimeric with a part for the periphery of the second cylindrical shell 70.Specifically, a pair abutting part 62 is respectively equipped with the fitting portion 62a being formed as spill, and under the state that minor diameter part 61 clamps the second cylindrical shell 70, fitting portion 62a is chimeric with the protuberance 72 of the second cylindrical shell 70.About the Qian He of fitting portion 62a with protuberance 72, illustrate in back with Fig. 9 B.

In addition, the maximum outside diameter Dx of the second cylindrical shell 70 is below internal diameter D1 of the first cylindrical shell 60.Specifically, to be designed to the maximum outside diameter Dx of the second cylindrical shell 70 less than the internal diameter D1 of the first cylindrical shell 60 for the first cylindrical shell 60 and the second cylindrical shell 70.

Therefore, the second cylindrical shell 70 is inserted into the first cylindrical shell 60 as shown in Figure 4, thus when the second cylindrical shell 70 and the first cylindrical shell 60 combine, as shown in Figure 7, the first cylindrical shell 60 and the second cylindrical shell 70 can relatively rotate centered by axle.

In addition, as shown in Figure 8, in axis, the first cylindrical shell 60 and the second cylindrical shell 70 also can axially relatively move.In addition, the first cylindrical shell 60 possesses anti-delinking part 64, and this anti-delinking part 64 is configured in the side in the both sides of axial minor diameter part 61, is formed with the internal diameter (with reference to figure 1, Fig. 5 A and Fig. 8) less than the internal diameter of minor diameter part 61.Specifically, in present embodiment, be configured with light emitting module 10 at the first cylindrical shell 60, anti-delinking part 64 is configured in opposes side with light emitting module 10 in axial minor diameter part 61 both sides.

In present embodiment, this anti-delinking part 64, by abutting with the large-diameter portion 71 (a pair protuberance 72) of the second cylindrical shell 70, thus can prevent the second cylindrical shell 70 from deviating from from the first cylindrical shell 60.

In other words, the second cylindrical shell 70, in the scope that large-diameter portion 71 does not abut with anti-delinking part 64, can move axially relative to the first cylindrical shell 60, and thus, the length of the axis of framework 50 can steplessly change.

In addition, when second cylindrical shell 70 is positioned at certain position (axial position) relative to the first cylindrical shell 60, make the second cylindrical shell 70 centered by axle, rotate the angle of less than 90 ° relative to the first cylindrical shell 60, thus fix the position relative to the first cylindrical shell 60 of the second cylindrical shell 70.

Fig. 9 A represents the figure of the first cylindrical shell 60 and the first case of the relative turned position of the second cylindrical shell 70, and Fig. 9 B represents the figure of the first cylindrical shell 60 and the second case of the relative turned position of the second cylindrical shell 70.

Such as shown in Figure 9 A, second cylindrical shell 70 is fixed as and does not rotate centered by axle, when first cylindrical shell 60 is rotated with the clockwise direction in Fig. 9 A, a pair abutting part 62 that the minor diameter part 61 of the first cylindrical shell 60 has respective, abuts with the protuberance 72 of the second cylindrical shell 70.

In this state, the first cylindrical shell 60 is rotated a little in a clockwise direction, the first cylindrical shell 60, according to the frictional force between a pair abutting part 62 and a pair protuberance 72, becomes temporary fixed state relative to the second cylindrical shell 70.

The following describes the state utilizing this temporary fixed, for the ligthing paraphernalia 3 (with reference to figure 3) of bulb-shaped lamp 1 erection sequence one example.

Such as, when bulb-shaped lamp 1 being installed to ligthing paraphernalia 3, till abutting with anti-delinking part 64 with a pair protuberance 72, pull out the state of the second cylindrical shell 70 from the first cylindrical shell 60, the first cylindrical shell 60 is carried out temporary fixed relative to the second cylindrical shell 70.In addition, under that state, rotate the first cylindrical shell 60 in a clockwise direction, make lamp holder 90 be screwed into the lamp socket 4 of ligthing paraphernalia 3.In addition, when the first cylindrical shell 60 is rotated, the cover 80 being arranged on the first cylindrical shell 60 is specifically made to rotate.

In that case, a pair abutting part 62 of the first cylindrical shell 60 respective, be the state abutted with the protuberance 72 of the second cylindrical shell 70, thus, along with the rotation of the first cylindrical shell 60, the second cylindrical shell 70 having installed lamp holder 90 also rotates in a clockwise direction.Its result, lamp holder 90 being screwed into or roughly having completed for lamp socket 4.

Afterwards, the direction of the cover 80 of bulb-shaped lamp 1 to ligthing paraphernalia 3 (ceiling 200) is pushed, abuts with the around openings of the main part 5 of the cover 80 with ligthing paraphernalia 3 that make bulb-shaped lamp 1.Thus, first cylindrical shell 60 temporary fixed relative to the second cylindrical shell 70 moves axially, and makes the length (length of the axis of bulb-shaped lamp 1) of the axis of framework 50, becomes the length of the ligthing paraphernalia 3 being applicable to being embedded in ceiling 200.

In addition, in this condition, the first cylindrical shell 60 is made to rotate in a clockwise direction.In that case, lamp holder 90 is because lamp socket 4 is in the state of limited in rotation, so the limited in rotation system of the second cylindrical shell 70, thus, the first cylindrical shell 60 rotates in a clockwise direction relative to the second cylindrical shell 70.

Thus, the elastic deformation at least partially of the first cylindrical shell 60 and the second cylindrical shell 70 or plastic deformation, such as shown in Figure 9 B, the abutting part 62 becoming the first cylindrical shell 60 clamps the state of the second cylindrical shell 70 in radial direction.In other words, the first cylindrical shell 60 becomes formal fixing state relative to the second cylindrical shell 70.Its result, being limited relative to the first moving axially of cylindrical shell 60 of the second cylindrical shell 70, thus stably can maintain the length of framework 50.

In addition, the second cylindrical shell 70 pushes in radial direction relative to the inner surface of the first cylindrical shell 60, so also inhibits the first cylindrical shell 60 loosening relative to the second cylindrical shell 70.Thus can suppress to loosen because of wind etc. the noise etc. produced.

In addition, in present embodiment, the second cylindrical shell 70 has more than one protuberance 72, this protuberance 72 is configured in periphery, the more than one protuberance 72 chimeric with fitting portion 62a, in the state that the second cylindrical shell 70 is clamped by minor diameter part 61, accepts the part of the pushing force from minor diameter part 61.More specifically, as shown in Figure 9 B, a pair protuberance 72 that the large-diameter portion 71 of the second cylindrical shell 70 has respective, chimeric with the fitting portion 62a that the abutting part 62 of the first cylindrical shell 60 has.

Thus, such as, in order to make the first cylindrical shell 60 formally fix relative to the second cylindrical shell 70, and when rotating first cylindrical shell 60, the first cylindrical shell 60 can be suppressed to rotate too much.In other words, protuberance 72 and fitting portion 62a become the first cylindrical shell 60 carries out formal fixing angle of rotation benchmark relative to the second cylindrical shell 70, and play a role as the position of restriction angle of rotation.In addition, protuberance 72 have at least one just passable.In other words, even if when the second cylindrical shell 70 only has one protuberance 72, a protuberance 72 is chimeric with fitting portion 62a, thus such as can limit the angle of rotation of the first cylindrical shell 60.

Bulb-shaped lamp 1 of the present embodiment like this, possesses the framework 50 of storage light-emitting module 10, and framework 50 has first cylindrical shell 60 in outside and the second cylindrical shell 70, first cylindrical shell 60 of inner side and the second cylindrical shell 70 can carry out axial relative movement.

In addition, the first cylindrical shell 60 has minor diameter part 61, and the first cylindrical shell 60 rotates centered by axle relative to the second cylindrical shell 70, thus minor diameter part 61 becomes the state clamping the second cylindrical shell 70 in radial direction.The angle of rotation in this time is less than 90 °.

Form according to this, in bulb-shaped lamp 1, can by stepless for the length of the axis of framework 50 change, and, stably maintain the length after changing.In addition, the constructional relation of the first cylindrical shell 60 that this feature is had by the framework 50 of bulb-shaped lamp 1 and the second cylindrical shell 70 generates, and there is no need for the mechanism of the complexity generating this feature.In other words, at bulb-shaped lamp 1, do not need to use the parts except the first cylindrical shell 60 and the second cylindrical shell 70, just can adjust the length of the axis of framework 50 and fixing after adjusting.

At this, about fixing after the change of the length of framework 50, such as, imagine the situation of being fixed by screw from the side of framework 50.Under this imagination, when bulb-shaped lamp 1 being installed to ligthing paraphernalia 3 (with reference to figure 4), bulb-shaped lamp 1 is installed to ligthing paraphernalia 3 and after adjusting the length of framework 50, needs first from ligthing paraphernalia 3 bulb dismounting shape lamp 1 and stubborn screw.

But, in bulb-shaped lamp 1 of the present embodiment, carry out fixing after the change of the length of framework 50 by the first cylindrical shell 60 relative to the second cylindrical shell 70 rotation.Therefore, as mentioned above, after the change of the length of framework 50, do not need first to dismantle ligthing paraphernalia 3 from bulb-shaped lamp 1.In other words, the length after the length adjustment of framework 50 and adjustment fixing, can be installed in the installation process of ligthing paraphernalia 3 at bulb-shaped lamp 1 and carry out.

As mentioned above, bulb-shaped lamp 1 of the present embodiment can construct with simple the overall illumination light source that stretch.

This external bulb-shaped lamp 1 of the present embodiment, minor diameter part 61 has a pair abutting part 62, clamps the second cylindrical shell 70 by a pair abutting part 62.Therefore, the first cylindrical shell 60 fixing relative to the second cylindrical shell 70 can such as more positively be carried out.In addition, such as, by the size etc. that change a pair abutting part 62 is respective, thus the profile of the first cylindrical shell 60 can not be changed, adjust the bed knife of the first cylindrical shell 60 relative to the second cylindrical shell 70.

In addition, bulb-shaped lamp 1 possesses as follows: be incorporated in framework 50, for making the drive circuit 40 of light emitting module 10 luminescence; And be configured in the lamp holder 90 from the end that the first cylindrical shell 60 exposes of the second cylindrical shell 70, this lamp holder 90 be the electric power accepted from outside is supplied to drive circuit 40 lamp holder.Lamp holder 90, the general lamp holder of E26 type that the bulb-shaped lamp that such as uses in average family can be adopted common etc.

Therefore, such as, bulb mounting shape lamp 1 on the ligthing paraphernalia that can possess at common house, and total length can stepless changing, thus such as can be adjusted to the appropriate length corresponding to the size of ligthing paraphernalia.

In addition, the order of the installation of the ligthing paraphernalia 3 of the bulb-shaped lamp 1 of described explanation is an example, and bulb-shaped lamp 1 can be installed to various ligthing paraphernalia according to other orders.Such as, the first cylindrical shell 60 is not carried out temporary fixed relative to the second cylindrical shell 70, but lamp holder 90 is screwed into the lamp socket of ligthing paraphernalia.

In other words, when the first cylindrical shell 60 is not carried out temporary fixed relative to the second cylindrical shell 70, by making the first cylindrical shell 60 rotate, thus a pair abutting part 62 of the first cylindrical shell 60 become the state abutted with the protuberance 72 of the second cylindrical shell 70 separately.Afterwards, along with the clockwise rotation of the first cylindrical shell 60, the second cylindrical shell 70 also rotates in a clockwise direction, thus lamp holder 90 can be screwed into lamp socket.

In that case, after lamp holder 90 is screwed into lamp socket, the first cylindrical shell 60 is moved axially relative to the second cylindrical shell 70, and the first cylindrical shell 60 is rotated further clockwise.Thus, the fixing end of the adjustment of the length of framework 50 and the length after adjusting.

In addition, the structure of framework 50 that embodiment relates to can be the structure beyond the structure shown in Fig. 1 ~ Fig. 9 B.At this, with Figure 10 ~ Figure 12 B, the various variation about framework 50 are described.

(variation 1)

The abutting part 62 of framework 50, first cylindrical shell 60 related at described embodiment has the fitting portion 62a chimeric with a part for the periphery of the second cylindrical shell 70.The shape of this fitting portion 62a is not defined as the shape shown in Fig. 5 A.

Such as, the abutting part 62 of the first cylindrical shell 60 has fitting portion, and the shape of this fitting portion is the rotation in a direction of restriction second cylindrical shell 70, easily allows the shape of rightabout rotation.

Figure 10 is the bottom view of the shape representing the fitting portion 62b that the variation 1 of embodiment relates to.

Such as shown in Figure 10, arrange fitting portion 62b at the abutting part 62 of the first cylindrical shell 60, this fitting portion 62b has and the radial parallel or almost parallel inner surface of the first cylindrical shell 60 and the inner surface relative to radial skew.In that case, as shown in Figure 10, arrange protuberance 72a in the periphery of the second cylindrical shell 70, this protuberance 72a has the radial parallel or almost parallel side with the second cylindrical shell 70.

In that case, in Fig. 10, by making the first cylindrical shell 60 with side's rotation clockwise, when fitting portion 62b is chimeric with protuberance 72a, fitting portion 62b and protuberance 72a, the surface orthogonal with the tangential direction of the rotation of the first cylindrical shell 60 abuts against.Therefore, the first cylindrical shell 60 rotates further clockwise relative to the second cylindrical shell 70, is practically impossible.

Thus, in order to make the first cylindrical shell 60 formally fix relative to the second cylindrical shell 70, thus when the first cylindrical shell 60 is rotated, more positively can suppress the rotation that the first cylindrical shell 60 is too much.

On the other hand, when the first cylindrical shell 60 is rotated counterclockwise relative to the second cylindrical shell 70, fitting portion 62b and protuberance 72a, abuts against on the surface of the inclination of the tangential direction of the rotation close to the first cylindrical shell 60.In other words, when rotating counterclockwise, fitting portion 62b is more shallow state with the mutually embedding of protuberance 72a, so easily carry out the first cylindrical shell 60 rotating counterclockwise relative to the second cylindrical shell 70.

Thus, the first cylindrical shell 60 easily removes formal fixing state after becoming formal fixing state relative to the second cylindrical shell 70.Therefore, such as change installed the situation of the ligthing paraphernalia of bulb-shaped lamp 1 inferior required, become easy for the operation of the length adjusting framework 50 again.

(variation 2)

The abutting part 62 of framework 50, first cylindrical shell 60 related at described embodiment has the fitting portion 62a of spill, and the protuberance 72 of the second cylindrical shell 70 is inserted into fitting portion 62a, thus abutting part 62 is chimeric with protuberance 72.But, also can be the position that the abutting part of convex is inserted into the spill arranged at protuberance, thus abutting part be chimeric with protuberance.

Figure 11 is the bottom view of the shape of the abutting part 65 and protuberance 75 representing that the variation 2 of embodiment relates to.

Such as shown in Figure 11, in the inner circumferential of the first cylindrical shell 60, be provided with the abutting part 65 of convex in radial direction.In addition, be provided with protuberance 75 in the periphery of the second cylindrical shell 70, this protuberance 75 has the position of the spill of size that abutting part 65 can insert and shape.

Even if in this situation, there is the minor diameter part 61 of a pair abutting part 65, also can clip the large-diameter portion 71 with a pair protuberance 75 diametrically.In other words, the minor diameter part 61 of the first cylindrical shell 60 by clamping the second cylindrical shell 70 in radial direction, thus can limit the movement of the axis of the second cylindrical shell 70.

In addition, abutting part 65 is chimeric with protuberance 75, such as, in order to the first cylindrical shell 60 is formally fixed relative to the second cylindrical shell 70, thus when the first cylindrical shell 60 is rotated, can suppress the rotation that the first cylindrical shell 60 is too much.

(variation 3)

The basic configuration in framework 50, first cylindrical shell 60 related at described embodiment and the cross section orthogonal to the axial direction of the second cylindrical shell 70 is toroidals.In addition, respectively radial recessed or convex position is provided with to the first cylindrical shell 60 and the second cylindrical shell 70, thus the minor diameter part 61 realizing the first cylindrical shell 60 clamps the structure of the second cylindrical shell 70 in radial direction.

But the basic configuration in the cross section orthogonal to the axial direction of the first cylindrical shell 60 and the second cylindrical shell 70 there is no need to be toroidal, such as, this cross section also can be oval.

Figure 12 A is the first cylindrical shell 160 of relating to of the variation 3 of embodiment and the cross sectional shape of the second cylindrical shell 170 and the first figure of relation thereof.Figure 12 B is the first cylindrical shell 160 of relating to of the variation 3 of embodiment and the cross sectional shape of the second cylindrical shell 170 and the second figure of relation thereof.

The framework 50 that this variation relates to possesses the first cylindrical shell 160 and the second consubstantiality 170, and this second consubstantiality 170 is configured to be inserted into the first cylindrical shell 160, can move axially relative to the first cylindrical shell 160.

The cross section vertical with axis of the inner circumferential of the first cylindrical shell 160 is elliptical shapes.In addition, with the periphery of the second cylindrical shell 170 be elliptical shape with axially vertical cross section.

At the first cylindrical shell 160 of such shape, as shown in Figure 12 A and Figure 12 B, have minor diameter part 161, this minor diameter part 161 is formed with the internal diameter less than the maximum outside diameter of the second cylindrical shell 170.Minor diameter part 161, the mode abutted with minor diameter part 161 with the part being formed with maximum outside diameter of the second cylindrical shell 170, the first cylindrical shell 160 rotates centered by axle relative to the second cylindrical shell 170, thus clamps the second cylindrical shell 150 in radial direction.

Specifically, the maximum outside diameter Dx of the second cylindrical shell 170 is the length of the major diameter of the periphery of the elliptical shape being equivalent to the second cylindrical shell 170.In other words, by the two end portions of the major axis of the second cylindrical shell 170, form the large-diameter portion 171 of this variation.

In addition, a pair abutting part 162 of minor diameter part 161 is the parts at the two ends of the minor axis A of the inner circumferential of the elliptical shape being positioned at the first cylindrical shell 160.In addition, the internal diameter (length of minor axis A) of minor diameter part 161 is less than the length of maximum outside diameter Dx.

Have under the state shown in the first cylindrical shell 160 of such shape and size and the second cylindrical shell 170, Figure 12 A, the first cylindrical shell 160 can move axially relative to the second cylindrical shell 170.From this state, when such as being rotated clockwise by the first cylindrical shell 160, as shown in Figure 12 B, the minor diameter part 161 (a pair abutting part 162) of the first cylindrical shell 160, becomes the state clamping the second cylindrical shell 170 in radial direction.

Thus, being limited in the relative movement of axis of the first cylindrical shell 160 and the second cylindrical shell 170, stably can maintain the length of the axis of framework 50.

Thus, bulb-shaped lamp 1 possess that this variation relates to framework 50 when, also can realize with the flexible overall bulb-shaped lamp 1 of simple structure.In addition, the first cylindrical shell 160 and the second cylindrical shell 170, because the shape that utilization is overall (oval barrel shape) limits movement each other, so do not need to be formed such as the spill of this restriction or the position of convex.

In addition, as long as to be elliptical shapes just passable for the cross sectional shape inner circumferential of the first cylindrical shell 160, such as periphery can be toroidal.Further, as long as to be elliptical shapes just passable in the cross sectional shape periphery of the first cylindrical shell 170, such as inner circumferential can be toroidal.
