Detailed description of the invention
Below, according to illustrated embodiment, the present invention is described.Fig. 1 represents illuminating lamp 10 of the present invention, and this illuminating lamp 10, as also represented at Fig. 2 and Fig. 3, is consisted of combination heat sink 20, spherical lampshade 30, light-emitting substrate 40 and these main members of lamp socket portion 50.
Heat sink 20, as also represented in the downside at Fig. 2, the metal materials such as the such as aluminium using thermal conductivity good, the upper end be provided with tubular, by opening, upper end outer peripheral face 21 is formed with the pin thread 22a in the portion of tightening 22 becoming that side of heat sink 20.In addition, in order to make hook when tightening easy, pin thread 22a is divided into 2 parts with the length shorter than half cycle in circumference and is formed.
Further, on the outer peripheral face of the portion of tightening 22 close beneath, be formed in this heat sink 20 axially with the fin 24 that multiple row is outstanding.In addition, these fins 24 partially arrange the fin of same shape in circumference.
Fin 24 longitudinal tensile strain ground is formed, give prominence to formation while there is during side-looking upside-down triangle shape, the end face 24a on top has approximate horizontal square and be formed on the outer peripheral face of light-emitting substrate 40 highlightedly, and lower end is on the face identical with the outer peripheral face of heat sink 20.In addition, the width of the circumference of fin 24 and the length of the groove width be formed between fin 24 and fitting portion 70 (groove portion 24c) are cardinal principle equal length.And the end face 24a of this fin 24 is corresponding with the holding section 34 of spherical lampshade 30 described later.
And, although the end face 24a of fin 24 also can be tabular surface, if but as also represented in fig. 2, the surface roughness of the end face 24a of fin 24 is done slightly, then improve the contact resistance with the holding section 34 in the face of this fin 24, strengthen integration, so, preferably the end face 24a of fin 24 is arranged coarse.Such as, towards the direction orthogonal with circumference on the end face 24a of fin 24, in other words, towards being formed radially many jagged V-shaped grooves, on surface is formed, concavo-convex anti-slip part 29 is defined cursorily.If form such anti-slip part 29, then improve the contact resistance of the reverse directions of spherical lampshade 30, the anti-loosening performance of spherical lampshade 30 improves further.
Further, in the inner circumferential side of the open end 23 of heat sink 20, as shown in Figure 3, the step-like locking stage portion 25 for installing light-emitting substrate 40 is formed.This locking stage portion 25 is the stage portion inner peripheral surface side of upper end outer peripheral face 21 being defined otch with cross section L shape, makes the bight on the downside of the periphery of light-emitting substrate 40 snugly be clipped in this locking stage portion 25.In addition, the open end 23 of heat sink 20 is considered heating when having installed light-emitting substrate 40 to arrange fully wide inner space around.Further, on the base plate 26 of within it side, wear and the light-emitting substrate 40 electrical resistance ground through hole 27 that imports of the distribution that is connected.
Spherical lampshade 30, by hemispherical cover the light transmission of the open end 23 of heat sink 20, the resin material with some elastic deformabilities forms, the open end 31 of this spherical lampshade 30 is arranged to heavy wall with major diameter, and the inner peripheral surface of this open end 31 is formed the negative thread 32a in the portion of tightening 32 becoming spherical that side of lampshade 30.And, make the formation that portion of tightening 22,32 i.e. pin thread 22a that the mutual open end 23,31 that makes to overlap with spherical lampshade 30 at heat sink 20 is formed and negative thread 32a tightens and links.Further, the open end 33 of spherical lampshade 30, is arranged to the external diameter of the end face 24a size in opposite directions of the fin 24 from top and heat sink 20, is also equipped with outstanding holding section 34 downwards at the open end 33 of this spherical lampshade 30.
Holding section 34 as shown in Figure 4, is the holding section arranged slightly highlightedly with trapezoidal grade at the open end 33 of spherical lampshade 30, arranges this holding section 34 when the ester moulding of spherical lampshade 30 in one piece.Namely, identical materials with spherical lampshade 30, as long as this holding section 34 does not produce large distortion when pressurizeing, carry out the material of elastic deformation with the degree not damaging pressurization function, such as, can use the resin material such as polypropylene with sufficient spring rate, intensity.
The concrete shape of this holding section 34, be by link about spherical lampshade 30 and heat sink 20 fasten fasten the front surface 35 that direction of rotation becomes front raised floor, make the inclined plane 35a of the obtuse angle θ 1 tilting to rise smoothly from the open end 33 of this spherical lampshade 30, to fasten about this holding section 34 rear surface 36 that direction of rotation becomes rear raised floor, make locking 36a of right angle or the acute angle theta 2 risen with steep angle from the open end 33 of this spherical lampshade 30.
And, as shown in Figure 4, flatly linking front surface 35 is the contact surface 34a substantially horizontally contacted with the end face 24a of fin 24 with the face between rear surface 36, and the surface roughness of this contact surface 34a also can be made thicker, improves the contact resistance with the end face 24a of fin 24 further.
In addition, holding section 34 have employed improves into maximum, that rotation is stopped formation by contact suppressing with fin 24 moment of having fastened contacted, in addition, in order to obtain the function of the contact of the short transverse improving holding section 34, as shown in Figure 4, be only set very little by the projecting height h of holding section 34, such as 0.2mm degree, just can obtain sufficient contact.And, be tightened on heat sink 20 making spherical lampshade 30, be near completion before fastening, holding section 34 contacts in circumference with fin 24 from being gently pressed onto and suppressing, but because holding section 34 has elasticity, so, do not hinder the function in the portion of tightening 22,32, implement the rotation process of spherical lampshade 30 all the time with good accuracy smoothly.
This holding section 34, can be located at the all-round of open end 33, also can be dispersed into multiple setting equably in circumference.In this embodiment, give prominence in the position of 180 degree of the circumference different left and right sides holding section 34 forming same shape with each 3 ground of a constant pitch.Further, the pitch of the circumference of holding section 34 is formed as the pitch (interval) identical with the pitch of circumference of end face 24a of fin 24.Therefore, when the rotation of spherical lampshade 30, each holding section 34 contacts corresponding with identical opportunity with each fin 24.
Further, at the open end 31 of spherical lampshade 30, the inner peripheral surface comparing the portion of tightening 32 and be in upside is formed for light-emitting substrate 40 is installed locking below 37, below locking, 37 are formed as inverted L-shaped shape by the mode forming breach.Thus locking below 37 and the locking stage portion 25 of above-mentioned heat sink 20 and inner circumferential bight 25a described later and breach stage portion 43, form the clamping part 28 from clamping light-emitting substrate 40 described later up and down.
Light-emitting substrate 40, the disk light-emitting components such as LED 41 (being 2 in figure 3) have been mounted in central portion, being formed by materials such as the good aluminium of thermal conductivity, edge, periphery 42 is easy in the installation being provided for this light-emitting substrate 40, form the breach stage portion 43 with the inner circumferential bight 25a of locking stage portion 25 also locking corresponding inverted L-shaped shape, except the edge, periphery 42 of light-emitting substrate 40, breach stage portion 43 also carry out locking have accordingly improve light-emitting substrate 40 location and form in the clamping of the adhesion of heat sink 20.
Lamp socket portion 50, accommodates the not shown electric power loop supplying commercial power to above-mentioned light-emitting component 41, printed wiring dish has carried various electronic unit.Therefore, electric power loop is connected through not shown distribution electrical resistance with light-emitting component 41.In addition, the lamp socket 51 for being connected with external power source is possessed in bottom.
When assembling the illuminating lamp 10 formed like this, before the installation of heat sink 20 and spherical lampshade 30, first on the open end 23 of heat sink 20, carry light-emitting substrate 40 in the mode of the edge, periphery 42 loading light-emitting substrate 40 in locking stage portion 25 as shown in Figure 3.Now, the breach stage portion 43 of light-emitting substrate 40 is also locking corresponding with the locking stage portion 25a of heat sink 20, so one side correctly can position one side lift-launch light-emitting substrate 40 to light-emitting substrate 40, the installation exercise of light-emitting substrate 40 improves.
After this light-emitting substrate 40 of lift-launch, make the portion of tightening 32 of spherical lampshade 30 corresponding with the portion of tightening 22 of heat sink 20 in the mode covered above this light-emitting substrate 40, if make spherical lampshade 30 rotate to fastening direction, then tighten the pin thread 22a in portion 22,32 and negative thread 32a and tighten and fasten.
Now, complete until fastening, as as shown in the upper enlarged drawing of Fig. 5, the holding section 34 outstanding downwards of spherical lampshade 30 is not effectively pressed against on end face 24a above as fin 24, that be formed flatly, so, although rotate, but fasten be near completion before holding section 34 effectively contact with the end face 24a of fin 24 gradually, now because the front surface 35 of holding section 34 becomes inclined plane 35a, so, even if with the angular contact of fin 24, also climb up, allow slip, can rotate to fastening direction.Thereafter, the support extreme position effectively abutted with the end face 24a of fin 24 in holding section 34 completes fastening.Fastened the moment at this, spherical lampshade 30 terminates relative to the installation of heat sink 20.
In addition, after having fastened, improve contact by the holding section 34 and fin 24 of suppressing contact up and down, and rely on the strong frictional force in the portion of tightening 22,32 occurred as its reaction, rotational resistance when having fastened uprises.Therefore, once after fastening spherical lampshade 30, relative to fastening direction of rotation much less, even if also not simply relax relative to anti-direction of rotation of fastening.And, if make the surface of the contact surface 34a of holding section 34 and the end face 24a both sides of fin 24 become slightly define concavo-convex anti-slip part 29, moment then when having fastened in the concavo-convex correspondence of anti-slip part 29 of the anti-slip part 29 of the contact surface 34a of holding section 34 and the end face 24a of fin 24 locks, so, link effect when having fastened improves further, and the lax danger being arranged on the spherical lampshade 30 on heat sink 20 disappears.Even if spherical lampshade 30 relaxes, slightly reverse, also as shown in the lower enlarged drawing of Fig. 5, the holding section 34 of slightly having reversed embeds the groove portion 24c between fin 24, the rear surface 36 (locking 36a) of the holding section 34 that embedded in abuts with the vertical plane 24b of fin 24, and the reversion of spherical lampshade 30 is limited completely.
In addition, when in the installation of spherical lampshade 30 on heat sink 20, because the locking of spherical lampshade 30 37 is pushed down above the periphery of light-emitting substrate 40 below, so, light-emitting substrate 40 is clamping edge, periphery 42 up and down by heat sink 20 and spherical lampshade 30, while the installation of spherical lampshade 30, the installation of light-emitting substrate 40.Now, light-emitting substrate 40 is by from clamping up and down, be adjacent in that side of heat sink 20, so, although use illuminating lamp 10 and make light-emitting substrate 40 generate heat by light-emitting component 41 etc., the fin 24 on the outer peripheral face of the heat carrying out light-emitting substrate 40 since then near heat sink 20 is close to it expeditiously transmits.Therefore, illuminating lamp 10 can not only improve assembling, and also plays superior effect in the raising of thermal diffusivity.In addition, when the use of illuminating lamp 10, in heat sink 20, the illumination light of the light-emitting component 41 that side is luminous is through hemispheric spherical lampshade 30, exports uniform luminous.
Fig. 6 represents another clamping configuration example of light-emitting substrate 40, using the upper surface of the upper end outer peripheral face 21 of heat sink 20 as 21a above locking, using this locking 21a above and the spherical lampshade 30 that described locking below 37 above-below direction forward surface between as the grasping part 61 of light-emitting substrate 40, the edge, periphery 42 of light-emitting substrate 40 is made to be clipped in this grasping part 61, from clamping it up and down.In this occasion, also in order to make the installation of light-emitting substrate 40 easy, below the edge, periphery 42 of light-emitting substrate 40, being formed with the breach stage portion 43 of inverted L-shaped shape, being made up of the clamping part 28 of light-emitting substrate 40 these clamp structures.Therefore, at clamping part 28 except the edge, periphery 42 of light-emitting substrate 40, breach stage portion 43 also carries out locking correspondence, improves the location of light-emitting substrate 40 and the adhesion at heat sink 20.Now, also can with spherical lampshade 30 tighten operation interlock, light-emitting substrate 40 is clamped.Particularly due to have employed the vertical direction when tightening spherical lampshade 30 chucking power from top according to spherical lampshade 30, the formation clamped is carried out under the state that the order of light-emitting substrate 40 and heat sink 20 has overlapped in the perpendicular direction, so, stable chucking power is obtained relative to light-emitting substrate 40, in addition, due to the space at overlapping 3 components of radial direction that grasping part 61 does not adopt the thickness of the radial direction increasing heat sink 20 such, as far as possible simply in the formation of short transverse overlap, so, compared with the formation of the clamping part 28 of Fig. 3, the thickness of heat sink 20 also can reduce.
Fig. 7 represents another embodiment of heat sink 20, the difference of this heat sink 20 is, the structure of the sag and swell of the fin 24 described in the above-described embodiments as an alternative (engaging recessed part, in other words, groove portion 24c), possesses recess 23b, other formation is identical, so, mark same Reference numeral, omit identical explanation, only difference is described.
Be equipped with the heat sink 20 of recess 23b, as shown in the downside of Fig. 7, by being formed in top cylinder portion 71 and doffing portion 72 integration, top cylinder portion 71 is by outside level and smooth male bend Surface forming, and doffing portion 72 is formed as straight tube-like in the bottom in top cylinder portion 71.The upper opening in top cylinder portion 71, is provided with the end face 23a of the ring-type of level on the peripheral part (defining the part of fin 24 in the above-described embodiments) of its open end 23.On this end face 23a, the many recess 23b part defining fin 24 in the above-described embodiments as fitting portion 70 is partially arranged in circumference.
Be formed in recess 23b here, there is in the position with holding section 34 circumference in opposite directions size and the degree of depth that this holding section 34 embeds, opening squarely when overlooking, in the occasion of other embodiment, be also all be formed as vertical plane about the recess front surface 73 fastening direction of rotation of spherical lampshade 30 and recess rear surface 74.That is, recess 23b is equivalent to the groove portion 24c between the fin 24 that illustrates in the embodiment of front surface.
In the figure 7, although illustrate an example of the heat sink 20 not having fin 24, also can adopt not hindering the position of recess 23b to form fin 24, improve the mode of thermal diffusivity and form.In addition, below in the same manner as above-described embodiment, doffing portion 72 of heat sink 20 is connected with lamp socket portion 50, possesses not shown connecting structure.
Using the occasion of the heat sink 20 constituted like this, also be make the portion of tightening 32 of spherical lampshade 30 lean against in the portion of tightening 22 of heat sink 20, if make spherical lampshade 30 rotate to fastening direction, then the pin thread 22a and the negative thread 32a that tighten portion 22,32 tighten, and fasten smoothly.
Now, complete until fastening, as also represented in Fig. 7, holding section 34 outstanding downwards on below spherical lampshade 30, not by press against fully be formed on heat sink 20 above on smooth end face 23a on, so, allow level and smooth rotation, but before fastening and being near completion, holding section 34 effectively contacts with the end face 23a of heat sink 20, now because the front surface 35 of holding section 34 becomes inclined plane 35a, so, as shown in Fig. 8 (B), even if contact with the upper corner 23c of recess front surface 73, holding section 34 also one side elastic deformation because of compression, one side to be slided rotation in the mode of climbing up upper corner 23c.Thereafter, holding section 34, as represented with imaginary line in Fig. 8 (B), when being in the support extreme position the most effectively abutted with the end face 23a of heat sink 20, fasteningly to complete.Fastened the moment at this, spherical lampshade 30 terminates (with reference to Fig. 8 (A)) relative to the installation of heat sink 20.
If because the spherical lampshade 30 such as Long-Time Service exists lax tendency after the installation of spherical lampshade 30, then stagger with the end face 23a up to the present abutted in holding section 34, embed and instead fasten in the recess 23c in direction, but now holding section 34 one side from contact release before this, recover by elasticity, one side makes the vertical rear surface 36 of the holding section 34 that embedded in abut with the vertical recess rear surface 74 of recess 23b, the rotation in lax direction is limited, further lax disappearance.Therefore, after assembling, spherical lampshade 30 can not relax and throw off.In this occasion, also can not only simplify installation constitution and the installation exercise of spherical lampshade 30, and the link that installation reliability is high can be guaranteed.
As described above, possesses little holding section 34 being tightened in the spherical lampshade 30 on heat sink 20, the counter-force from that side of heat sink 20 when holding section 34 is abutted with the end face 24a of fin 24 on the outer peripheral face being provided in the heat sink 20 or end face 23a of heat sink 20 acts on axially, the portion of tightening 22,32 and heat sink 20 end face 23a, 24a upper and lower between improve axial contact, heat sink 20 and spherical lampshade 30 can be firmly fixed.And, even the limited such place of installing space, also can install as the small-sized illuminating lamp 10 with easy shape, especially can with spherical lampshade 30 tighten operation interlock, that improves heat sink 20 and spherical lampshade 30 expeditiously fastens power, simultaneously have the installation function that the reliability of heat sink 20 and spherical lampshade 30 is high, one side can install spherical lampshade 30 simply.
