Background technology
As the new light sources that replaces existing fluorescent lamp and incandescent lamp, use is that the lighting device of master's light-emitting component is increasing with LED.Use is that main semi-conductive light-emitting component has following advantage with LED: small-sized, consumes electric power is little, illuminant colour and luminous pattern are controlled easily.
In the prior art, to single LED is sealed in the LED in the packing, imposes the resin profile and carry out light emitting control (for example, with reference to patent documentation 1).And, the document (for example, with reference to patent documentation 2) of the LED technology of light harvesting on liquid crystal panel that discloses (the back light) backlight that will be used for liquid crystal panel is also arranged.
On the other hand, in order to generate various illuminant colours and luminous pattern easily, the situation of adorning a plurality of LED in fact is more convenient.When arrangement had sealed the luminescence unit of each LED, it was following unfavorable to have, that is, owing to the sealing state of each LED inhomogeneous cause can't controlled side anticipation luminous pattern and illuminant colour.
In recent years, people arrange a plurality of LED, and the use computer program is controlled the illuminant colour and the luminous pattern of complicacy, during the LED that seals arranging individual package, can produce the inhomogeneous harmful effect that causes of sealing.These are especially more outstanding in fields such as recoil simulators.
Therefore, will realisticly adorn that a plurality of LED and a plurality of LED that will real dress concentrate sealing, and a plurality of LED's of control sealing is luminous.Especially in order to reduce real this and the sealing cost dressed up, realize the sealing of a plurality of LED in the time of will seeking common ground and to the control of LED light.
Under such situation, the real technology (for example, with reference to patent documentation 3,4) of adorning a plurality of light-emitting components has been proposed.
, when adorning in fact a plurality of light-emitting component, give the enough electric power of light-emitting component here, want to make it to carry out the luminous of high brightness.But, because light-emitting component produces high heat at dress face in fact, so can not give light-emitting component enough electric power.As a result, the lighting device of having adorned in fact a plurality of light-emitting components just can not send the light of high brightness.The structure that the heat that therefore, just need the real dress face of real dress light-emitting component be produced sends.The lighting device that possesses such radiator structure is suggested (for example, with reference to patent documentation 5,6).

Summary of the invention
In addition, patent documentation 2 discloses and concavees lens has been set in single led the place ahead and the light that LED sends is concentrated on the technology on the liquid crystal panel.This technology also is difficult to use in the situation of control light harvesting in a plurality of LED of sealing.
But, control light in order to make lenticular each lens respectively according to each LED of a plurality of LED, will produce the uneven problem of control.As signal or fishing lamp etc., the inhomogeneous meeting of each lens is given to generate based on the illuminant colour of a plurality of LED integral body and the necessity of luminous pattern and is produced harmful effect.And, use lenticule to have the problem that cost rises.
The structure that patent documentation 3 can not solve the structure that has sealing LED respectively and control light makes the inhomogeneous problem that rises with cost of photocontrol.
But, because the technology of patent documentation 4 is to be that benchmark seals a plurality of LED with the lens board, so exist the light emitting control of LED to rely on the problem of the precision of lens board.And, also there is the sealing of LED also to rely on the size of lens board and the problem of durability, the luminous problem of control when being not suitable for concentrating a plurality of LED and sealing in addition.
But patent documentation 5 disclosed lighting devices only have exothermic structure on the substrate of real dress LED.Therefore, be trapped in LED from the fin liberated heat near, the temperature of the entire space of real dress LED can't reduce, and just can not give LED higher electric power.As patent documentation 5; If just real dress monomer LED, only through be set directly at like this fin on the real dress substrate dispel the heat just enough, real when adorning many LED and wanting to give each LED higher power; If the formation of patent documentation 5 that kind, heat-sinking capability is just not enough.
In addition, patent documentation 6 discloses through the substrate of a plurality of light emitting diodes arranged side by side and has carried heat that light emitting diode sends and with the lighting device of fan heat radiation.
But, patent documentation 6 disclosed lighting devices because just with heat delivery to a direction of the light emitting diode that forms a line, so real when adorning a plurality of light emitting diode the conveying of heat just insufficient.Especially, if need the lighting device of high brightness, light-emitting component is easily with the real dress of clathrate, only by to the structure of a direction transfer heat abundant transfer heat just.In addition, as patent documentation 6, only come transfer heat through common real dress substrate, we can say that heat delivery is inadequate, real dress light-emitting component will be not suitable for for a long time.And, owing to be transfer heat and with the formation of fan heat radiation in the plane, so also exist heat to be trapped near the problem the real dress substrate of light emitting diode easily.
That is, the technology of patent documentation 5,6 exists and can not adorn a plurality of light-emitting components in fact and to make these heats away near the real dress substrate and the problem of emitting.
As stated, the lighting device of prior art has the structure of a plurality of LED of sealing and the structure of control light respectively, has the problem that control is inhomogeneous or cost rises of light.Especially, with lighting device, street lamp, tunnel interior lighting device, recoil simulator or fishing lamp etc., during with the whole control illumination of a plurality of LED, control the luminous of a plurality of LED equably when need and seal as engineering at concentrated a plurality of LED.There is the problem that can't satisfy such requirement in prior art.
In addition, when sealing a plurality of light-emitting components and being sitting in lighting device, require to be applicable to the device that with lighting device, street lamp, tunnel interior lighting device, recoil simulator or fishing lamp etc., needs high brightness as engineering.That is,, need give a plurality of light-emitting components higher electric power in order to obtain high brightness.
If give a plurality of light-emitting components higher electric power, light-emitting component will send high heat.Lighting device need make these heats emitted away from light-emitting component periphery and quilt.If these heats are emitted away from light-emitting component periphery and quilt, the temperature of light-emitting component periphery will rise, and just can not give light-emitting component enough electric power.
As stated, there is following problem in the lighting device of prior art: a plurality of light-emitting components can not real be adorned with low cost in (1), (2) can not give the higher electric power of a plurality of light-emitting components so that its high brightness luminescent, (3) can not make heat that a plurality of light-emitting components send away from the real dress space of light-emitting component and emitted.
The present invention is in view of above problem; Purpose is to provide a kind of lighting device; This lighting device is suitable for engineering with lighting device, street lamp, tunnel interior lighting device, recoil simulator or fishing lamp etc.; The real light emitting control of the most suitable a plurality of LED that realizes when dressing up this can reduced, even and also can the heat of light-emitting component be emitted with high brightness luminescent.
For solving said problem, lighting device of the present invention, it possesses: real dress substrate; Be installed on a plurality of light-emitting components on the real dress substrate; The sealing hoop is arranged on the real dress substrate and around a plurality of light-emitting components; Seal member, be filled in the sealing hoop inner and with sealed light emitting element when light-emitting component contacts; Heat diffusion portion is contained in reality dress substrate, the heat of light-emitting component is adorned the zone from the reality of a plurality of light-emitting components be diffused into the neighboring area; Hot delivery section will be carried to prescribed direction from the heat of heat diffusion portion; Radiating part will be shed to the outside by the heat that hot delivery section is carried; And seal member is transparent or semitransparent, and has at least a shape in concavity and the convex above it, seal member carry out the light that light-emitting component is sent spread and concentrate at least a operation.
Lighting device of the present invention can be taken into account sealing and the control of light that light-emitting component is sent of the light-emitting component of bare chip state through sealing hoop, seal member and lens board.Its result can reduce the reality of light-emitting component and dress up this.Seal necessary key element and then the necessary key element of light emitting control through dual-purpose, can take into account the sealing and light emitting control in cutting down cost.Especially, because real dress operation summary is dressed up this so further cut down reality.

Embodiment
At first, use Fig. 1, Fig. 2 that the whole summary of the lighting device of embodiment 1 is described.Fig. 1 is the side view of the lighting device of embodiment of the present invention 1.Fig. 2 is the front view with the lighting device of embodiment of the present invention 1.Fig. 1 is the state of the lighting device seen from the side, the light-emitting component of sealing hoop and the inner existence of seal member is made as visibility status shows.In addition, Fig. 2 is the state of the lighting device seen from above, the light-emitting component of sealing hoop and the inner existence of seal member is made as visibility status shows.
And seal member 5 is transparent or semitransparent, and the surface of seal member 5 has at least one in concavity and the convex.Constitute according to this, seal member 5 carries out at least one in light diffusion that light-emitting component 3 is sent and the operation of the concentrating.Constitute according to this, lighting device 1 can utilize the parts of sealed light emitting element 3, and the light suitable radiation that will send with a plurality of light-emitting components 3 of the real dress of bare chip state is to outside.
A plurality of light-emitting component 3 real real dress faces that are loaded on real dress substrate 2, but as shown in Figure 2, be fit to rectangular configuration and real dress.This is because through so rectangular real dress lighting device 1 ability high brightness, high irradiation power irradiation object thing.
The heat radiation of light-emitting component:
In addition, the real dress substrate 2 of adorning in fact a plurality of light-emitting components 3 comprises heat diffusion portion 7.Can be with real dress substrate 2 self as heat diffusion portion 7 (integrally formed) with real dress substrate 2, also can be in real dress substrate 2 set inside heat diffusion portion 7.The heat that heat diffusion portion 7 will be sent from the real dress face of light-emitting component 3 spreads to the neighboring area from the real real dress zone of adorning a plurality of light-emitting components 3.
Because heat diffusion portion 7 and hot delivery section 8 thermally coupleds, so hot thermotropism delivery section 8 conduction of heat diffusion portion 7 diffusions.Hot delivery section 8 will be conducted next heat delivery to prescribed direction from heat diffusion portion 7.The heat that transports arrives the radiating part 9 with hot delivery section 8 thermo-contacts, and radiating part 9 is emitted the outside with the heat that arrives.
A plurality of light-emitting components 3 are real to be loaded on real dress substrates 2, give a plurality of light-emitting component 3 higher electric power so that its can be with high brightness luminescent the time, a plurality of light-emitting components 3 can send higher heat at the real dress face of real dress substrate 2.This heat conducts to real dress substrate 2 from real dress face, but because real dress substrate 2 comprises heat diffusion portion 7, at first is dissipated to the neighboring area so these heats will expand through heat diffusion portion 7.Through with heat diffusion to the neighboring area, the heat that just can suppress to send in the real zone of adorning light-emitting component 3 (in this zone, it is luminous to need only light-emitting component 3, will generate heat) is excessive.And, because the heat that is spread is emitted the outside through hot delivery section 8 and radiating part 9, so the heat that light-emitting component 3 is produced is emitted continuously.
Like this, real dress substrate 2 comprises heat diffusion portion 7, and heat is delivered to the light emission direction opposition side of light-emitting component 3 from heat diffusion portion 7 is emitted the outside, can prevent thus heat be trapped on the light-emitting component 3 and light-emitting component 3 around.Its result can suppress the excessive phenomenon of heating of light-emitting component 3, so just can give light-emitting component 3 higher electric power, light-emitting component 3 just can be luminous with very high brightness.As a result, lighting device 1 just can shine the light of high brightness.Fig. 1, lighting device shown in Figure 21 can adorn a plurality of light-emitting components 3 and high power produced effectively emits to the heat of real dress substrate 2 from light-emitting component 3 owing to real, so can solve owing to the problem to light-emitting component 3 supply capabilities generation heat.
Promptly; A plurality of light-emitting components 3 are gone up by real and are adorned on the real dress plane (by adorning the plane that substrate 2 forms in fact) along certain plane; Heat diffusion portion 7 is the heat diffusion of sending with a plurality of light-emitting components 3 along this reality dress plane; Hot delivery section 8 is along carrying the heat that comes from heat diffusion portion 7 diffusions with direction of this real dress crossing on the same level, and radiating part 9 is emitted the outside with it.Like this, lighting device 1 heat that can the real a plurality of light-emitting components 3 that are loaded on the real dress plane be sent is carried and is emitted to three-dimensional.As a result, can not make heat be trapped in a plurality of light-emitting components 3 around, be easy to supply with higher powers to light-emitting component 3.
Especially the heat majority that sends of light-emitting component 3 all produces (on the promptly real dress substrate 2) on the real dress face.Heat through heat diffusion portion 7, hot delivery section 8 and radiating part 9 should reality dress face produce is emitted the outside in the zone by light-emitting component 3 three-dimensional segmentation.As a result, be difficult for being detained heat near light-emitting component 3 and the light-emitting component 3, the temperature that has suppressed light-emitting component 3 rises.The result of this inhibition can give light-emitting component 3 higher electric power, and lighting device 1 just can be with the high brightness irradiates light.
Light by the lighting device irradiation:
Describe with situation lighting device 1 irradiates light light-emitting component 3 is luminous.
A plurality of light-emitting components 3 are adorned on the substrate 2 through wire bonding or real being loaded in fact of ball bar (ball-grid).Give light-emitting component 3 supply capabilities by this real dress.By the electric power of this supply, light-emitting component 3 is luminous.In addition, a plurality of light-emitting components 3 have indigo plant, inherent colour such as red, green respectively.Through to 3 supply capabilities of the light-emitting component with inherent colour separately, a plurality of light-emitting components 3 send the light of blueness, redness, green, secondary colour.
Around a plurality of light-emitting components 3, be provided with sealing hoop 4, sealing hoop 4 inside are filled with resin etc. and are raw-material seal member 5.Seal member 5 touches with the surface or the flanked of a plurality of light-emitting components 3, and seals a plurality of light-emitting components 3.Seal member 5 is protected light-emitting component 3 through sealing.In addition, on the basis that sealing hoop 4 is set, be filled with seal member 5, so seal member 5 has and the shape, big or small corresponding shape and the size that seal hoop 4.
The surface of seal member 5 (top) has at least one in concavity and the convex, at least one the operation of carrying out the light that sends from a plurality of light-emitting components 3 is concentrated and diffusion of sealing parts, light is sent out to the outside thus.That is, seal member 5 performances will be incident upon the outside from the illumination that light-emitting component 3 sends to the light emitting control function of light-emitting component 3.
That is, need not add unnecessary parts and just can realize sealing and luminous, so lighting device 1 does not need unnecessary cost.And lighting device 1 is to concentrate and to seal on the basis of a plurality of light-emitting components 3 control luminous, therefore can each light-emitting component 3 luminous and sealings inhomogeneous.And, because sealing can realize in same parts simultaneously with light emitting control, just do not have and seal and the imbalance of light emitting control, thereby prevent luminous inhomogeneous.Particularly, owing to be to carry out light emitting control concentrating and seal under the state of a plurality of light-emitting components 3, so lighting device 1 can and make realization light harvesting or diffusion on its luminous basis at concentrated a plurality of light-emitting components 3.
The lamination of lens board:
In addition, lighting device 1 also can have the formation of lamination lens board 6 on seal member 5.Through having lens board 6, sealing plate 5 is concentrated or diffusion with the light that lens board 6 can send a plurality of light-emitting components 3 more effectively.As a result, lighting device 1 can be controlled more effectively by a plurality of light-emitting components 3 and penetrate to the illumination of outside.
Fig. 3, Fig. 4 are the side views of the lighting device of embodiment of the present invention 1.Fig. 3, Fig. 4 have shown the formation of lamination lens board 6 on seal member 5.
As Fig. 3, shown in Figure 4, lens board 6 is lamination on seal member 5.Lens board 6 has convex lens or concavees lens shape, on the lamination face of seal member 5, comes lamination according to the shape of the curved surface of lens board 6.When being filled in seal member 5 in the sealing hoop 4, because seal member 5 is molten resins etc., so just form the shape of the lamination face of seal member 5 easily according to the shape of lens board 6.As a result, seal member 5 just can contact with the smooth curved surface of following current with lens board 6.
In Fig. 3, the surface of seal member 5 has the curved surface of concavity, and the lens board 6 of lamination is convex lens on seal member 5.On the other hand, in Fig. 4, the lens board 6 of lamination is concavees lens on the seal member 5.
That is, seal member 5 and lens board 6 are controlled the light that a plurality of light-emitting components 3 send altogether and are made it expose to the outside.Compare with the situation of having only seal member 5,, can realize meticulousr light emitting control in conjunction with under the situation of lens board 6.
And lamination lens board 6 on seal member 5, lens board 6 are also brought into play the effect of protection seal member 5.The result of these situation, through seal member 5 and lens board 6, lighting device 1 can be concentrated and seal a plurality of light-emitting components 3 and concentrate and carries out light emitting control and illumination is incident upon the outside.
Utilize Fig. 2, describe carrying out light-struck situation by lighting device 1 under the state of seeing in above lighting device 1 (front).Fig. 2 has shown the state of seeing lighting device from above, is present in sealing hoop 4 and shows with visibility status with sealing hoop 4 inner light-emitting components 3.
In lighting device shown in Figure 21, sealing hoop 4 around with a plurality of light-emitting components 3 be one around.It is roughly rounded when here, sealing hoop 4 is seen from above.The inside of the sealing hoop 4 of circular is real is equipped with a plurality of light-emitting components 3, so the light that a plurality of light-emitting component 3 sends is with circular diffusion or concentrated, with regard to the light emission direction and the lighting angle of easy adjustment lighting device 1.Certainly, sealing hoop 4 also can be substantially elliptical or polygon.
In addition, when seeing, be sequential lamination, but, see light-emitting component 3 so can see through both because lens board 6 and seal member 5 are translucent or transparent with lens board 6, seal member 5, light-emitting component 3 from above.As a result, the light transmission lens board 6 and the seal member 5 that send of light-emitting component 3 exposes to the outside.At this moment, the curved surface diffusion that forms of the light scioptics plate 6 that sends of light-emitting component 3 and seal member 5 or concentrate.
At this moment, that kind as shown in Figure 3, when lens board 6 was convex lens, because the refraction of convex lens, the light that light-emitting component 3 sends concentrated on the irradiation object and shines.This situation is shown in arrow A.Seal member 5 is incident upon outside along arrow A with the illumination that light-emitting component 3 sends with lens board 6.Lens board 6 is effective when thinking Visual Confirmation illumination from afar for the situation of convex lens.
On the other hand, that kind as shown in Figure 4, when lens board 6 was concavees lens, because the refraction of concavees lens, the light that light-emitting component 3 sends diffused on the irradiation object and shines.This is deeply in love condition shown in arrow B.Seal member 5 is incident upon outside along arrow B with the illumination that light-emitting component 3 sends with lens board 6.Lens board 6 is effective when equal extent is shone in the scope of wanting to see for the situation of concavees lens.
Like this, the light that light-emitting component 3 sent according to the shape of the surface configuration (curved surface) of seal member 5 and lens board 6 of lighting device 1 is concentrated or diffusion and expose to the outside.
In addition, adorn on the substrate 2 from sealing formation lighting device 1 under the state that hoop 4 to lens board 6 is real dress, so lighting device 1 mobility is excellent, can be used as a unit combination in various machines real.Because lighting device 1 can be concentrated and seal a plurality of light-emitting components 3 and concentrated carry out light emitting control, so in the most suitable device that is combined in the higher luminous quantities of needs such as lighting device in recoil simulator, fishing lamp, the tunnel, street lamp.
As stated, sealing hoop 4 inside are concentrated and be sealed in to the lighting device 1 of embodiment 1 with a plurality of light-emitting components 3, can prevent the inhomogeneous of each light-emitting component 3 sealings thus.In addition, through at inner lamination seal members 5 of sealing hoop 4 and lens boards 6, can the light that a plurality of light-emitting components 3 send be concentrated and controls.Especially; Sealing hoop 4, seal member 5 contact respectively with lens board 6 (do not need not to represent very tight physics contact; But expression is not tangible released state) state, seal hoop 4, seal member 5 and lens board 6 thus and can take into account the function of a plurality of light-emitting components 3 of sealing and control luminous function.
By above-mentioned situation, lighting device 1 can be realized sealing function and light emitting control function to light-emitting component 3 with less parts.The result just can reduce cost.
In addition, in Fig. 1-Fig. 4,, with symbol " 3 " expression, also can understand with same symbol to other light-emitting component to a light-emitting component in a plurality of light-emitting components for guaranteeing the clear of figure.
Control to the heat of light-emitting area from light-emitting component:
Then, with reference to Fig. 5 the emitting of heat that the light-emitting component 3 from lighting device 1 conducts to light-emitting area described.Fig. 5 is the side view of a part of the lighting device of embodiment of the present invention 1.
The engineering that requirement lighting device 1 is suitable for needing high brightness is with the lighting device in lighting device, street lamp, the tunnel, recoil simulator or fishing lamp etc.Therefore, for making light-emitting component 3, just need give light-emitting component 3 higher current value or higher voltage value with high brightness luminescent.Because high brightness is luminous like this, light-emitting component 3 can produce high heat.Here, a plurality of light-emitting components 3 can be from real dress face, light-emitting area and the side evolution of heat.
In these heats that light-emitting component 3 sends, the heat that sends from real dress face spreads through heat diffusion portion 7, and Jie emits the outside by hot delivery section 8 from radiating part 9.Emitting as stated of this heat.
On the other hand, in these heats that light-emitting component 3 sends, the heat that sends from light-emitting area and side conducts to seal member 5.This is because seal member 5 passes through light-emitting area and the light-emitting area of side and light-emitting component 3 and the cause of side thermo-contact of sealed light emitting element 3.Thus, seal member 5 receives the heat that light-emitting component 3 sends.
In addition, for sealed light emitting element 3, seal member 5 adopts molten resin etc.Because it is poor that molten resin etc. and metal etc. are compared heat conductivity, so in most cases seal member 5 can be accumulated the heat that sends from light-emitting component 3.If seal member 5 is accumulated the heat that sends from light-emitting component 3, lighting device 1 malfunction can occur, infringement or fault occur.For avoiding such problem, just need to reduce current value or the magnitude of voltage that gives light-emitting component 3.But; If reduce the current value or the magnitude of voltage that give light-emitting component 3; The luminosity of light-emitting component 3 will reduce, and lighting device 1 just is difficult to be applicable to that the engineering that needs high brightness is with the lighting device in lighting device, street lamp, the tunnel, recoil simulator or fishing lamp etc.
Heat-conduction component 50 be located at seal member 5 inner and with 4 thermo-contacts of sealing hoop.Thus, heat-conduction component 50 can conduct to sealing hoop 4 by next heat (heat that promptly sends from light-emitting component 3) by seal member 5.Sealing hoop 4 is exposed to the outside, can be released to the outside from the heat that heat-conduction component 50 receives.Especially, because sealing hoop 4 is formed by the high resin of metal, alloy or heat conductivity etc.,, sealing hoop 4 is discarded to outside, substrate, basket etc. so will conduct next heat.Such result, the heat that sends from least a portion of the light-emitting area of light-emitting component 3 and side just can not be accumulated in seal member 5 inside, and emits the outside via heat-conduction component 50 and sealing hoop 4.
Like this, the heat-conduction component 50 seal member 5 inner heats that can will accumulate heat are easily effectively emitted the outside.
In addition, sealing hoop 4 has fin at least a portion of its surface and side, thus, can emit the outside from the heat that heat-conduction component 50 conduction come.Fig. 6 is the front view of the lighting device of embodiment of the present invention 1.Fig. 6 has shown from the illumination of lighting device 1 and has penetrated the state that direction is seen.That is the STA representation of a plurality of light-emitting components 3 of, the transparent or semitransparent seal member 5 of perspective being adorned in fact is in Fig. 6.
In addition, as shown in Figure 6, heat-conduction component 50 has not the lattice shape that the real holding position with a plurality of light-emitting components 3 repeats.Through such lattice shape, just do not hinder the luminous of light-emitting component 3.
To emitting of the heat of real dress face and emitting to the heat of light-emitting area:
As stated, the lighting device of embodiment 11 is through the combination of heat diffusion portion 7, hot delivery section 8 and radiating part 9, is created in heat on the real dress face in the heat that can a plurality of light-emitting components 3 be sent and emitted in the zone that is separated with light-emitting component 3.That is the heat that, produces at real dress face is being emitted with light-emitting component 3 three-dimensional separate areas.And, when seal member 5 is provided with heat-conduction component 50,, is created in heat on the light-emitting area in the heat that can a plurality of light-emitting components 3 be sent and is emitted in the zone that is separated with light-emitting component 3 through heat-conduction component 50, sealing hoop 4 and fin 40.That is the heat that, produces in light-emitting area is being emitted with the three-dimensional separate areas of light-emitting component.
In Fig. 5, represent the path that emits of these heats with arrow G, arrow H.Heat in that the light-emitting area of light-emitting component 3 produces is emitted the outside along arrow G, is emitted the outside at the heat that the real dress face of light-emitting component 3 produces along arrow H.Through the heat radiation of these two systems, near light-emitting component 3, just be difficult for being detained heat, just can suppress the temperature rising on every side of light-emitting component 3 and light-emitting component 3.That is, the heat radiation through the system mixed by arrow G, arrow H just can further improve the inhibition to the temperature rising of light-emitting component 3.
Like this, rise through the temperature that suppresses light-emitting component 3, just can give light-emitting component 3 higher electric power, lighting device 1 just can be with the high brightness irradiates light.Through with this high brightness irradiates light, lighting device 1 just is applicable to that for example engineering is with the lighting device in lighting device, street lamp, the tunnel, recoil simulator or fishing lamp etc.
Certainly, the heat radiation along the path of arrow G that is made up of heat-conduction component 50, sealing hoop 4 and fin 40 not necessarily constitutes.
Then, each parts is elaborated.
Real dress substrate:
At first, real dress substrate is described.
In addition, real dress substrate 2 can pass through the real dress of electricity light-emitting components 3 such as wire-bonded, flip-chip or ball bar, and will be arranged at real adorn inside and outside the substrate 2 the signal of telecommunication of other circuit give light-emitting component 3.
That is, real dress substrate 2 forms the basic configuration of lighting device 1, and gives a plurality of light-emitting component 3 signals of telecommunication.The shape of real dress substrate 2 can be set according to the number of a plurality of light-emitting components 3 with size, and the user mode in the time of also can being used for lighting device 1 according to it is set.In addition, real dress substrate 2 has and except light-emitting component 3, can also adorn sealing hoop 4 such bonding planes in fact and also help enforcement of the present invention.

In addition, light-emitting component 3 has inherent colour respectively, comes luminous according to current value that is applied and magnitude of voltage.Can the light-emitting component with identical inherent colour 3 be concentrated and arranges, also can arrange according to different inherent colours.In addition, each a plurality of light-emitting component 3 can also can be connected in parallel connection.Certainly, also can be under the state of parallel connection and series hybrid, a plurality of light-emitting components 3 are electrically connected.
The sealing hoop:
Then, sealing hoop 4 is described.
In addition, at least one will be confirmed according to the number of light-emitting component 3 in the height of sealing hoop 4 and the aperture area.Become big because if the number of light-emitting component 3 seals the periphery of hoop 4 more, so the aperture area of sealing hoop 4 becomes big.And, if the number of light-emitting component 3 comes the luminous quantity of self-emission device 3 just to become big more, therefore being the more light of reflection, the height of sealing hoop 4 just uprises.
Owing to be filled with seal member 5 in the sealing hoop 4, preferably seal the periphery sealing of hoop 4.This is because seal member mostly 5 is a molten resin, is in to prevent that the molten resin of filling from spilling the needs of sealing hoop 4 outsides.Therefore, sealing hoop 4 is a hoop component, and is just passable as long as this hoop component is arranged on the real dress substrate 2.
In addition, sealing hoop 4 possesses fin 40 as required.Fin 40 is situated between and by seal member 5 (according to circumstances also possibly be through heat-conduction component 50) light-emitting component 3 is emitted the outside at the heat that light-emitting area produces.Fin 40 can be integrally formed with sealing hoop 4, also can after on sealing hoop 4 that it is bonding, bonding etc.
Seal member:
For example, after sealing hoop 4 was set, the resin of fusion flowed into sealing ring hoop 4 inside.During inflow,, use automatic filling device relatively good in order not produce air layer and air bubble.After the inflow, through the reduction of temperature, the hardening of resin of fusion is harmonious with the profile of sealing hoop 4 and forms the seal member 5 of solid.
In addition, also heat-conduction component 50 back filling seal members 5 can be set in advance.This be because, seal member 5 is under the situation of the molten resin of in sealing hoop 4, filling, and fills molten resins if heat-conduction component 50 backs are set in advance, then since solidify seal member 5 can sealed light emitting elements 3 and seal heat-conduction component 50.
Certainly, the seal member 5 of the state through will having sealed heat-conduction component 50 is filled (settings) to form seal member 5 also passable sealing hoop 4 inside.
Perhaps, also can confirm the shape of the aspect that goes up according to the shape of lens board 6.This be since lens board 6 under the situation of the upper strata of seal member 5 lamination, the cause that the upper shape of seal member 5 is confirmed by the shape of this lens board 6.For example, when lens board 6 was convex lens, the upper strata mask of seal member 5 had the concavity curved surface, and when lens board 6 was concavees lens, the upper strata mask of seal member 5 had convex curved surface.
Heat-conduction component:
Then, heat-conduction component 50 is described.
Heat-conduction component 50 is arranged at seal member 5 inside.Heat-conduction component 50 will be conducted to sealing hoop 4 by the heat that light-emitting component 3 conducts to seal member 5.The heat that conducts to sealing hoop 4 is emitted the outside by sealing hoop 4.
In order the seal member 5 inner heats that exist to be conducted to sealing hoop 4, heat- conduction component 50 and 4 thermo-contacts of sealing hoop.Therefore, for example the end of heat-conduction component 50 contacts and also helps enforcement of the present invention with sealing hoop 4.Heat-conduction component 50 will be conducted to sealing hoop 4 by the heat that light-emitting component 3 conducts to seal member 5, therefore be fit to form this heat-conduction component by the high material of heat conductivity.For example, metal, alloy etc.As one of them example, heat-conduction component 50 is formed by pyroconductivity height such as copper, aluminium, silver, aluminium alloy, iron, ferroalloy, stainless steel or the high metal of rust-preventing characteristic (or durability).
In addition, heat-conduction component 50 is taken on the function that the heat of seal member 5 is conducted to sealing hoop 4, is incident upon outside inconvenience but the illumination of sending from light-emitting component 3 can occur hindering.Therefore, as shown in Figure 3, heat-conduction component 50 has the lattice shape that is formed by thermally-conductive materials and also is fit to.For example, heat-conduction component 50 also can have by the high resin of metal, alloy or heat conductivity form netted.Heat-conduction component 50 has lattice shape, can the heat of seal member 5 be conducted to sealing hoop 4 thus and can not hinder the irradiation of the light that sends from light-emitting component 3.This is because the light that sends from light-emitting component 3 can spill from the lattice shape void area.When especially giving light-emitting component 3 high current values or magnitude of voltage light-emitting component 3 with high brightness luminescent, the heat-conduction component 50 of lattice shape just is difficult for hindering luminous.Particularly lighting device 1 be used for recoil simulator, engineering with that kind such as lighting device, tunnel interior lighting device, street lamp and fishing lamp require brightness but when not requiring the machine of high-precision luminous or color development, heat-conduction component 50 just is difficult for becoming and hinders the luminous reason of light-emitting component 3.
In addition, when heat-conduction component 50 has lattice shape, as long as have the lattice shape of the arrangement pitch of the number that meets light-emitting component 3, light-emitting component 3.For example, to meet the arrangement pitch of light-emitting component 3 also suitable for the number of the void area of lattice shape and area.In addition, heat-conduction component 50 can also have the lattice shape of the frame formation of circle, ellipse, polygon etc. except having the lattice shape that square frame is formed.Certainly, so long as can conduct the heat of seal member 5 and can not hinder the shape of the irradiation of the light that sends from light-emitting component 3, what shape can.
Heat-conduction component 50 can be arranged at the inside of seal member 5, but also can be arranged on the seal member 5 light-emitting component 3 and top between any position on.For example, light-emitting component 3 with above roughly centre position on, it is inner just passable that heat-conduction component 50 is arranged at seal member 5.
As stated, heat-conduction component 50 is arranged at seal member 5 inside, and the heat of at least a portion of light-emitting component 3 and seal member 5 is conducted to sealing hoop 4.The heat that conducts to sealing hoop 4 is emitted the outside and is also emitted the outside from the fin 40 that is arranged on the sealing hoop 4 from sealing hoop 4.Like this, heat-conduction component 50 effectively conducts to the heat of light-emitting component 3 in the light-emitting area generation and the outside sealing hoop 4 that contacts.Especially will be trapped in seal member 5 inner heats easily and conduct to sealing hoop 4, therefore, becoming around the light-emitting component 3 is difficult for being detained heat.
Lens board:
Then, lens board 6 is described.Lens board 6 as required lamination in the upper strata of seal member 5.Perhaps, lens board 6 uses when lighting device 1 is made for the surface configuration that forms seal member 5.Lens board 6 is laminated layer on seal member 5.Lens board 6 is concentrated or diffusion with the light that sealing hoop 4 and seal member 5 send a plurality of light-emitting components 3.The shape of lens board 6 and structure are used for controlling the light that light-emitting component 3 sends.
When the lamination that lighting device 1 only has sealing hoop 4, seal member 5 and a lens board 6 just can be adorned a plurality of light-emitting component 3 with low cost reality with its sealing and carry out light emitting control.
Heat diffusion portion:
Heat pipe has through the condensing heat of capturing radiator of the gasification repeatedly of the cold-producing medium in the inner space that is sealed in crested on every side and with the function of its diffusion.
An example to heat diffusion portion 7 with heat pipe structure describes.For example, heat diffusion portion 7 possesses upper board, and the lower panel of upper board subtend, single or a plurality of intermediate plates of lamination between upper board and lower panel.The inner space that is formed by upper board, lower panel and intermediate plate can seal cold-producing medium, and the cold-producing medium of gasification moves on the diffusion of vapor path that intermediate plate forms, and condensing cold-producing medium moves on the capillary stream that intermediate plate forms.In addition, diffusion of vapor path and capillary stream with the heat of light-emitting component 3 near the heat diffusion portion center with radial diffusion.At this moment, the cold-producing medium of gasification moves at least one direction of the horizontal direction of diffusion of vapor path and vertical direction, and condensing cold-producing medium is mobile at least one direction of the horizontal direction of capillary stream and vertical direction.But, the dull and stereotyped space that the lamination of upper board and lower panel forms because the inner space is is so heat diffusion portion 7 is along the direction dissipate heat on real dress plane.
Utilize Fig. 7, Fig. 8 that the details of heat diffusion portion 7 is described.
Fig. 7 is the side exploded view of the heat diffusion portion of embodiment of the present invention 1.Fig. 8 is the inside front view of the heat diffusion portion of embodiment of the present invention 1.Fig. 7 is that the state that respectively upper board, lower panel and intermediate plate is separated shows, Fig. 8 is that the dismantle upper board of heat diffusion portion 7 shows can see inner mode.
At least one of upper board 71, lower panel 72 and a plurality of intermediate plate 73 has copulational protuberance.Upper board 71, lower panel 72 and a plurality of intermediate plate 73 be lamination on the basis that position relation is harmonious, and directly engages and integrated through hot pressing.At this moment, each parts directly engages through copulational protuberance.
Here; Directly engage and be meant; Under the state of the face driving fit that makes two parts that will engage, heat-treat in the pressurization; Be to engage through making at the interatomic force that acts between the face between the atom securely, said direct joint does not use cement and can make between the face of two parts integrated.At this moment, copulational protuberance is realized firm joint.Its result can make heat diffusion portion 7.
In addition, intermediate plate 73 has grooving portion 74 and internal run-through hole 76.In Fig. 8, shown the grooving portion 74 of cutting away, and shown the internal run-through hole 76 on the parts that are arranged on beyond the grooving portion 74 with radial.Grooving portion 74 forms diffusion of vapor path 75, and internal run-through hole 76 forms capillary stream 77.Diffusion of vapor path 75 forms radial from the approximate centre of heat diffusion portion 7.The part of the remainder of the diffusion of vapor path 75 of this radial formation becomes the zone that forms capillary stream 77.
Thus, inner space 79 along a plurality of diffusion of vapor paths 75 on the plane of the in-plane of inner space 79 and a plurality of capillary streams 77 adjacency respectively.Especially, that kind as shown in Figure 8, diffusion of vapor path 75 is arranged also with the mode of mutual adjacency with capillary stream 77 and is fit to.Like this; On the plane of the direction of heat diffusion portion 7 dissipate heat; Arrange with the mode of a plurality of capillary stream 77 mutual adjacency respectively with a plurality of diffusion of vapor paths 75; Cold-producing medium in the gasification of the approximate centre of heat diffusion portion 7 moves to the neighboring area with radial, and the cold-producing medium condensing in the neighboring area of heat diffusion portion 7 moves to approximate centre with radial.Moving of cold-producing medium through this gasification and condensing cold-producing medium, heat diffusion portion 7 can be with radial dissipate heat.
At this moment, with the position of the approximate centre subtend of heat diffusion portion 7 are real dress zones of fashionable dress light-emitting component 3, so heat diffusion portion 7 can diffuse to the neighboring area from the real dress zone of real dress light-emitting component 3 with the heat of light-emitting component 3.
In addition, diffusion of vapor path shown in Figure 8 75 and capillary stream 77 be shaped as an example, as long as can spread the heat of light-emitting component 3, other formation also can.In addition, according to the situation of real dress, light-emitting component 3 is real when being loaded on heat diffusion portion 7 end subtends regional, and is just passable with capillary stream 77 forming diffusion of vapor path 75 to the mode of peripheral dissipate heat from this end.
In addition, the recess 78 that possesses at least one connection of diffusion of vapor path 75 and capillary stream 77 of at least one of upper board 71 and lower panel 72 also is fit to.Through recess 78, the cold-producing medium of gasification or condensing cold-producing medium become easily and to move or to move to other zones from the part of capillary stream 77 to capillary stream 77 from diffusion of vapor path 75.As a result, heat diffusion portion 7 can be read dissipate heat soon.
Each several part to constituting heat diffusion portion 7 is elaborated.
Upper board:
In addition, on the face that joins with inner space 79 of upper board 71 (with the cold-producing medium of gasification or condensing cold-producing medium), having metal coating at least also is fit to.This is because apply metal coating, surface state modification, the cold-producing medium that can promote to gasify mobile.As metal coating, from gold, silver, copper, aluminium, nickel, cobalt and these metals such as alloy, select just can.Certainly, individual layer plated film, multicoating, electroplating film, electroless coating film any can.
Though upper board 71 has the address on " top ", be not the top that must be disposed at physically, the address for the purpose of just making things convenient for.The real dress substrate 2 of real dress light-emitting component 3 can join with upper board 71 and also can join with lower panel 72.Perhaps, on heat diffusion portion 7 during directly real dress light-emitting component 3, real dress light-emitting component 3 on the surface of the surface of upper board 71 or lower panel 72.
Lower panel:
Though lower panel 72 has the address of " bottom ", be not must be in configuration downwards physically, the just address for the purpose of the convenience.Real dress substrate 2 can join with lower panel 72 and also can join with upper board 71.
Intermediate plate:
Single or a plurality of intermediate plates 73 are lamination between upper board 71 and lower panel 72.Intermediate plate 73 is lamination between upper board 71 and lower panel 72, so be fit to have the tabular identical with upper board 71, by forming with upper board 71 identical materials.In addition, because lamination, it is fit to have the size identical with upper board 71 and lower panel 72, but also can be that slightly little size is in order to form inner space 79.
Here, grooving portion 74 forms the radial of that kind as shown in Figure 8, and diffusion of vapor path 75 also forms radially thus, and the cold-producing medium of gasification is radial to be moved.Certainly, condensing cold-producing medium also moves with radial.If change the shape of grooving portion 74, heat diffusion portion 7 just can be controlled the moving direction of the cold-producing medium that gasifies and condensing cold-producing medium, thereby can change the heat diffusion direction of light-emitting component 3.This is because capillary stream 77 is formed on the part beyond the grooving portion 74.
Here, capillary stream 77 forms through internal run-through hole 76, so decided the structure of capillary stream 77 by the lamination state of intermediate plate 73.
For example, if when intermediate plate 73 is single, the internal run-through hole 76 whole formation capillary streams that are arranged on the intermediate plate 73 are just arranged.
Relative thus, when intermediate plate 73 is a plurality of, be arranged at only some coincidence of internal run-through hole 76 on a plurality of intermediate plates 73 respectively, just form the area of section capillary stream 77 littler than the area of section of the horizontal direction in internal run-through hole 76.Like this, when intermediate plate 73 is a plurality of, form the area of section little capillary stream 77 of the area of section, so the condensing cold-producing medium in the capillary stream 77 more effectively moves than internal run-through hole 76 self.Especially, through the lamination of a plurality of intermediate plates 73, internal run-through hole 76 overlaps on the thickness direction of heat diffusion portion 7.Because this overlaps, form the capillary stream 77 of along continuous straight runs and vertical direction.As a result, condensing cold-producing medium can move along capillary stream 77 in the horizontal direction with on the vertical direction.Its result, heat diffusion portion 7 can make condensing cold-producing medium fast moving.
In addition, here, intermediate plate 73 is provided with a plurality of internal run-throughs hole 76.This is owing in order to bring into play the function as capillary stream 77, have a plurality of internal run-throughs hole 76 and help enforcement of the present invention.
Internal run-through hole 76 connects from the surperficial inwards of intermediate plate 73, and its shape can be circular, oval, square.Overlap between the part in internal run-through hole 76 and formation capillary stream 77, so internal run-through hole 76 is square proper.This is also more suitable from the easness of making.
Internal run-through hole 76 can through drive, formation such as pressurization, Wet-type etching, dry-etching, from processing and the machining accuracy aspect of smiling, form more suitable by etching and processing such as Wet-type etching, dry-etchings.
When intermediate plate 73 was a plurality of, internal run-through hole 76 was arranged at respectively on a plurality of intermediate plates 73.Here, the mode lamination of a plurality of intermediate plates 73 to overlap between the part that this internal run-through hole 76 is only arranged is so the intermediate plate 73 of each adjacency of position deviation in internal run-through hole 76 is proper.Depart from the mode that the area in internal run-through hole 76 overlaps respectively mutually the position in the internal run-through hole 76 on the position that for example, is positioned at the internal run-through hole 76 on certain intermediate plate 73 and other intermediate plates 73 that are positioned at this intermediate plate 73 adjacency.Like this, depart from mutually the position in the internal run-through hole 76 on the intermediate plate 73 of each adjacency, thus, during a plurality of intermediate plate 73 laminations, just forms the capillary stream 77 of the area of section less than the area of section on the horizontal direction in internal run-through hole 76.
In addition, in capillary stream 77, have condensing cold-producing medium to move, but the cold-producing medium that also has a gasification move.
In addition, the bight of the recess 78 of capillary stream 77 and the bight of grooving portion 74 are chamfering, but also R can be set.The section of capillary stream 77 can have various shapes such as hexagon, circle, ellipse, square, polygon.The section shape of capillary stream 77 is decided by the shape in internal run-through hole 76 and the coincidence system between the internal run-through hole 76.In addition, the area of section is also decided by same factor.
As stated, heat diffusion portion 7 near the real reality that is loaded on its approximate centre is adorned regional fool the heat diffusion of light-emitting component 3 to the neighboring area.Conducted to the hot delivery section 8 with its thermo-contact by the heat that spread.Hot delivery section:
Perhaps, for improving hot transfer efficiency, hot delivery section 8 likewise has the heat pipe structure with heat diffusion portion 7 and also is fit to.For example, that kind as shown in Figure 1, hot delivery section 8 has bar-like shape.The inside of this bar-like shape has the inner space that can seal cold-producing medium, and the inner space possesses the cold-producing medium steam passage that moves and the capillary stream that condensing cold-producing medium is moved of the gasification of making.Especially, hot delivery section 8 has steam passage and capillary stream along Y direction, and the cold-producing medium of gasification and condensing cold-producing medium are moved along Y direction.
For example, at the center of the inner space of hot delivery section 8 the capillary stream is set, it is also passable around it, steam passage to be set, and reverse situation also can.Like this, be divided into steam passage and capillary stream, can produce the cold-producing medium of gasification and moving of condensing cold-producing medium through inner space with hot delivery section 8, hot delivery section 8 rescue you with heat delivery to prescribed direction.
Radiating part:
Radiating part 9 is described.
Radiating part 9 is and the parts of hot delivery section 8 thermo-contacts, the heat that hot delivery section 8 is carried is emitted the outside.Through the heat radiation of this radiating part 9, light-emitting component 3 sends conduct in the heat of real dress face emitted the outside.As a result, the rising of the temperature of light-emitting component 3 is suppressed.
As long as radiating part 9 have can make heat emit outside formation what can.
For example, radiating part 9 has at least one in fin (heater sink), cooling fan, Peltier's element, heat sink and the liquid cooling sleeve pipe.Through these parts, the heat that hot delivery section 8 is carried is emitted the outside.In Fig. 1, for example, radiating part 9 has fin 91.Fin 91 can be emitted the outside along the direction identical with the hot throughput direction of hot delivery section 8 (Y axle) with heat from the bottom surface of hot delivery section 8.Certainly, fin 91 also can extend on the direction of intersecting with hot delivery section 8, if according to the appearance of lighting device 1 with whole constitute confirm that the formation of fin 91 is just passable.
In addition, as shown in Figure 9, the combination that radiating part 9 has heat sink 92 and cooling fan 93 also is fit to.Fig. 9 is the side view of the lighting device of embodiment of the present invention 1.
Radiating part 9 has heat sink 92.Heat sink 92 and hot delivery section 8 thermo-contacts receive the heat that hot delivery section 8 transports.Cooling fan 93 makes heat sink 92 inner generation convection current promote heat radiation to these heat sink 92 blowings.As a result, heat sink 92 can be discharged heat effectively.
Certainly, not that heat sink 92 but fin 91 is also passable with cooling fan 93 combinations.When using Peltier's element, at the outlet side of Peltier's element the liquid cooling sleeve pipe is set, the heat that cooling is moved Peltier's element also is fit to.
Like this, radiating part 9 has various parts, and radiating part 9 can be emitted the outside with the heat that hot delivery section 8 is carried thus.As a result, the heat that light-emitting component 3 sends can be emitted the outside, and just the temperature of ability light-emitting component 3 rises.The result who suppresses just can supply with the higher electric power of light-emitting component 3, and lighting device 1 just can be with the high brightness irradiates light.
As stated, emit the outside respectively at heat that produces on the light-emitting area and the heat that on real dress face, produces in the lighting device 1 of embodiment 1 heat that can light-emitting component 3 be produced.As a result, just can supply with higher electric power to light-emitting component 3, lighting device 1 just can be with the high brightness irradiates light.Such lighting device 1 just can be at the light that needs high brightness but is used the lighting field of Halogen lamp LED or incandescent lamp to use the light-emitting component of low-power such as LED and strong operability because of temperature problem etc.For example, lighting device 1 be suitable for using the light-emitting component of LED etc. fishing lamp, engineering with lighting device, street lamp, tunnel interior lighting device, recoil simulator or fishing lamp etc.
Then, embodiment 2 is described.
Figure 10 is the side view of the lighting device of embodiment of the present invention 2.In addition, in Figure 10, in lighting device 1, omitted the hermetically-sealed construction of light-emitting component 3.Sealing for light-emitting component 3 is identical with situation about explaining with Fig. 1 etc.Installation portion 10 holds heat diffusion portion 7.Therefore, installation portion 10 has recess 101, and this recess 101 holds heat diffusion portion 7.Heat diffusion portion 7 be contained in the real dress substrate 2 or with real dress substrate 2 one, or on real dress substrate 2 lamination, but heat diffusion portion 7 also might that kind shown in figure 10 lamination on real dress substrate 2.
Like this, during lamination heat diffusion portion 7, heat diffusion portion 7 is exposed the outside on real dress substrate 2.Installation portion 10 holds this heat diffusion portion 7.Hold this heat diffusion portion 7 through installation portion 10, heat diffusion portion 7 is connected with hot delivery section 8 easily.
For example, installation portion 10 possesses recess 102, in this recess 102, holds bar-shaped hot delivery section 8 thus.Thus, hot delivery section 8 also can be installed on the recess 102 of installation portion 10 in advance.Under the state that this hot delivery section 8 is mounted, installation portion 10 is installed on heat diffusion portion 7 on the recess 101, and through installation portion 10, hot delivery section 8 is connected with heat diffusion portion 7 easily.When this connected, when that kind shown in figure 10, heat diffusion portion 7 contacted with hot delivery section 8, heat diffusion portion 7 and hot delivery section 8 can realize thermo-contact through the installation to installation portion 10.Perhaps, even under the situation that heat diffusion portion 7 and hot delivery section 8 are separated in installation portion 10 inside, heat diffusion portion 7 also can be situated between with hot delivery section 8 and realize thermo-contacts by installation portion 10.The result of this thermo-contact can conduct to hot delivery section 8 with heat from heat diffusion portion 7 effectively.
Like this, through installation portion 10, heat diffusion portion 7 is mounted (and then hot delivery section 8 is mounted), and heat diffusion portion 7 just can realize thermo-contact with hot delivery section 8.
In addition, shown in figure 11, installation portion 10 also can have installs the pedestal 105 of hot delivery section 8 when supporting heat diffusion portion 7.Figure 11 is the side view of the lighting device of embodiment of the present invention 2.Pedestal 105 makes heat conduct to hot delivery section 8 from heat diffusion portion 7 effectively.This is because heat diffusion portion 7 has realized thermo-contact with hot delivery section 8 through pedestal 105 conscientiously.In Figure 11, be not both with the situation of Figure 10 and shown that real dress substrate 2 comprises the situation of heat diffusion portion 7.Pedestal 105 makes heat diffusion portion 7 and hot delivery section 8 thermo-contacts when supporting this heat diffusion portion 7.
Like this, installation portion 10 makes from the heat conduction efficiencyization of heat diffusion portion 7 thermotropism delivery section 8.
The lighting device 1 of embodiment 2 can make the installation and the ease of connection of heat diffusion portion 7 and hot delivery section 8, and can make the heat delivery efficient activity of light-emitting component 3.
Use Figure 12 that the situation that the machine that will throw light on is used for fishing lamp is described.Figure 12 is the skeleton diagram of user mode that shows the fishing lamp of embodiment of the present invention 3.Figure 12 has shown to make and uses electric wires etc. to hang fishing lamp down 110 from boats and ships 202 to shine marine 200 state.
Fishing lamp 110 possesses the lighting device 1 of explanation in embodiment 1,2.Lighting device 1 possesses the heat diffusion portion 7 of the heat that is used to spread light-emitting component 3 etc. on the real real dress substrate of adorning a plurality of light-emitting components 3.As explanation in the embodiment 1,2, the heat diffusion that heat diffusion portion 7 grades are sent light-emitting component 3, then carry and emit.
The lighting device 1 that fishing lamp 110 will have such formation is contained in basket 111 inside.In addition, shown in figure 12, it is marine 200 that fishing lamp 110 also might drop into, so basket 111 need carry out waterproof processing.In addition, fishing lamp 110 possesses power feeding section 112 from necessary electric power to lighting device 1 (being light-emitting component 3) that supply with.In Figure 12, power feeding section 112 is arranged at the outside of basket 111, but also can be arranged at inside.Perhaps, through with fishing lamp 110 be arranged at power feeding section on the boats and ships 202 by power line and link to each other and fetch to fishing lamp 110 supply capabilities.
Fishing lamp 110 irradiation marine 200 or seas 201.In Figure 12, it is marine 200 that the part of fishing lamp 110 drops into, and the light that light-emitting component 3 sends is marine 200 inside of such irradiation shown in arrow M, arrow N.This is owing to the mode of light-emitting component 3 towards marine 200 fishing lamp 110 is dropped into marine 200 cause.Certainly, do not drop into marine 200 but fixedly fishing lamp 110 so that light-emitting component 3 irradiation seas 201 are also passable.
The heat that light-emitting component 3 sends is through heat diffusion portion 7 diffusions.The heat of heat diffusion portion 7 diffusions is transported to prescribed direction by hot delivery section 8.As Figure 12 showed clearly, hot delivery section 8 arrived the direction away from sea 201 with heat delivery.This be since hot delivery section 8 with heat delivery to the dispersal direction of heat diffusion portion 7 diffusion just towards the direction (direction of stow away from heat light-emitting component 3) of radiating part 9.The heat that hot delivery section 8 is carried is emitted at radiating part 9 (possessing fin, cooling fan, fin, liquid cooling sleeve pipe, Peltier's element etc.).The space that emits is and marine 200 opposite sides, radiating part 9 liberated heats can with the extraneous gas mediate contact.Thus, radiating part 9 can more effectively be emitted heat.Certainly, according to the structure of basket 111, radiating part 9 liberated heats also can directly contact or and contact with sea water with extraneous gas.Or, making radiating part 9 directly or indirectly and contact with sea water seawater basket 111 inside of packing into according to the structure of basket 111, radiating part 9 can effectively be emitted heat thus.
That is, when fishing lamp 110 irradiations marine 200 or sea 201, the heat of light-emitting component 3 is emitted through the extraneous gas away from sea 201.That is, fishing lamp 110 can be released to the heat of light-emitting component 3 side opposite with emission side.Especially, lower away from the exterior gas space most cases temperature on sea 201, radiating part 9 just can be emitted heat effectively.Therefore, lighting device 1 can effectively be discarded to extraneous gas with the heat of light-emitting component 3.As a result, the temperature of light-emitting component 3 rises and is suppressed, and fishing lamp 110 can be with the high brightness irradiates light.
Especially, fishing lamp 110 if the temperature of said justice light-emitting component 3 rises too high, just has to control the brightness of light-emitting component 3 to be used for prerequisite for a long time.But if adopt the fishing lamp 110 of embodiment 3, through distinguishing use as irradiation side, the external world as heat radiation side with marine 200, the temperature that can suppress light-emitting component 3 rises.Certainly, drop into marinely 200 at interior fishing lamp even will comprise radiating part 9, radiating part 9 also can be released to heat in marine 200 the seawater, so can emit heat effectively.
In addition, engineering with lighting device, tunnel interior lighting device, recoil simulator, street lamp too.
In embodiment 4, the simulation result of the radiating effect of the lighting device explained among the embodiment 1-3 is described.
The inventor is respectively to comparative example and embodiment analogue formation, according to the heating of model assumption thermal source light-emitting component, the state of temperature at each position of compute illumination device.
Comparative example
Shown in figure 13, suppose that comparative example is the lighting device 300 of the heat diffusion portion 302 that possesses real dress thermal source 301, the pedestal 303 that supports heat diffusion portion 302 and the hot delivery section 304 of stretching out from pedestal 303.Figure 13 is the skeleton diagram with the corresponding lighting device model of the comparative example of embodiment of the present invention 4.Figure 13 (a) expression tilts to see the state of lighting device 300 from the top, Figure 13 (b) expression tilts to see the state of lighting device 300 from the below.Shown in Figure 13 (b), lighting device 300 has the inside 305.
