The size of piece so that area used in radiating increases, therefore can be realized the heat exchange than in the past bigger heat.
However, the deep research of people according to the present invention, confirming only is more than to imagine by increasing the size of fin not obtaining
Cooling effect.In addition, the size of script light irradiation device itself there is limitation, it is impossible to the unlimited size for increasing fin.
The present invention is in view of above-mentioned project, and it is an object of the present invention to provide a kind of before extremely large size is turned to not make the size of radiator
It mentions, the light irradiation device that cooling capacity is excellent.
Light irradiation device of the invention is characterized in that having:
Shell；
Light source portion, configuration inside the housing and be near the first face as one of face for constituting above-mentioned shell,
Include multiple solid light source elements；
Radiator adjacently configures in above-mentioned shell, and with above-mentioned light source portion, includes fin；And
Air inlet on the face of above-mentioned shell and is on the first party orthogonal with above-mentioned first face is upward out
The position in the first face is stated,
Above-mentioned fin has:
Multiple plate-shaped members, by will divide with the nonparallel plate face in above-mentioned first face along the direction parallel with above-mentioned first face
The secondth area liftoff to configure, which has the length of first area and above-mentioned first direction shorter than above-mentioned first area
Domain；
Inflow part, set on opposed with above-mentioned first face position on above-mentioned first direction, by above-mentioned multiple plate-shaped members
The above-mentioned first area portion detached from each other for the above-mentioned plate face being had is formed；And
Outflow portion is set to the position different with above-mentioned inflow part, by above-mentioned more on the direction parallel from above-mentioned first face
The above-mentioned plate face portion detached from each other that a plate-shaped member has is formed,
Above-mentioned light irradiation device has wind guide component, and the wind guide component is above-mentioned to have above-mentioned multiple plate-shaped members
Separation unit covering in the above-mentioned first area portion detached from each other of plate face, being made of the face parallel with above-mentioned first direction
Mode is arranged.
For only by increasing the reasons why size of fin can only be obtained lower than the cooling capacity imagined, the present inventor is for example following
Speculated like that.Fig. 1 is the attached drawing for showing schematically the flowing for imagining the cooling wind in the light irradiation device in example.Such as figure
Shown in 1, LED element 101 is configured to, with the direction configuration parallel with XZ plane, the cooling wind (air) obtained from air inlet 104
It is flowed along -Y direction, so that cooling wind collision is in radiator 102.Fig. 1 is attached drawing when observing in X direction.In fact, fin
103 are discretely configured with multi-disc plate-shaped member in X direction.
As shown in Figure 1, the case where contemplating the size for increasing fin 103 and lengthening the length of fin 103 of Y-direction.
At this point, cooling wind (cooling wind 112) collision of a part is circulated near the radiator 102 after radiator 102.It is another
Aspect, a part of cooling wind (cooling wind 111) contact fin 103 do not collide in radiator 102 but, but by than radiator
102 lean on the position of 104 side of air inlet.In other words, exist from the cooling wind that air inlet 104 obtains not by close to as heat
The cooling wind 111 of the position of the LED element 101 in source.This brings following enlightenment: although being increased by the size for increasing fin 103
Add the amount of the cooling wind obtained to the inside of fin 103, it but cannot be cooling by LED element 101 with increased air quantity.
Fig. 2 is to imitate Fig. 1 to show schematically construction disclosed Patent Document 2.In the example shown in Fig. 2, for general
From air inlet 104 supply wind efficiently guide fin 103 and be equipped with wind guide component 105.The wind guide component 105 is with by fin
The mode of a part covering of the XZ plane of 103 side opposite with radiator 102 configures.It is used for as a result, to fin 103
Inside obtains the limited size of the entrance (inflow part) of cooling wind, it can be expected that improving cold after getting the inside of fin 103
But the effect of the wind speed of wind.In addition, in the example in figure 2, for one direction of cooling wind direction that will import the inside of fin 103
The purpose of exhaust is equipped with wind guide component 106.
But even the construction, in the case where increasing the length of fin 103 of Y-direction as described above, also deposit
Do not passing through the cooling wind 111 close to the position of the LED element 101 as heat source.Therefore, the inside of fin 103 is got
A part of cooling wind will not play the cooling function of the LED element 101 that will become heat source.
In contrast, according to above-mentioned composition, the plate-shaped member for constituting fin, which is shown, to be had in the upstream towards cooling wind
Direction (first direction) on longer region (first area) and shorter region (second area) shape.Moreover, first
The separation unit separated in a first direction in the portion detached from each other of region constitutes the inflow part of cooling wind, and first area is mutual
The separation unit being made of the face parallel with first direction in separation unit is covered by wind guide component.As a result, being flowed into from inflow part
The cooling wind of the inside of fin is directed to outflow portion after the short second area side of the length for flowing into first direction.In other words
Say, it is in the cooling wind of the primary inside for flowing into fin, circulate near the radiator adjacently configured with light source portion it is cold
But the ratio of wind improves.As a result, hardly contributing to the ratio of the cooling wind of the cooling in light source portion reduces.
On the other hand, the plate-shaped member for constituting fin has the longer first area of length of first direction, therefore improves
The air quantity of the inside of fin can be got.As a result, it is possible to which the cooling wind of more air quantity to be got to the inside of fin, and
And the cooling wind of the acquisition can be made to flow through near light source portion with higher ratio.It, can be real as a result, compared with previous device
The higher cooling performance of size of existing fin.Embodiment is referred again in " specific embodiment " to explain in detail.
Here, in the present specification, " outflow portion " is also possible to the cooling wind for the inside for getting fin from first
The region that the region opposed with light source portion is flowed out outward on direction.That is, on the direction parallel with the first face, fin (plate
Component) exist in the case where than light source portion position in the outer part, it can be discharged using the position on the outside of this along first direction
The composition of cooling wind.In this case, " outflow portion " is not the cooling wind direction fin for referring to will acquire the inside of fin
The place of outside discharge, but refer to will acquire the outside in the cooling wind direction of the inside of the fin region opposed with light source portion
The place of discharge.
It is also possible to above-mentioned outflow portion set on the face of above-mentioned shell and is and the second face different from above-mentioned first face
The above-mentioned second area portion detached from each other of opposed position, the above-mentioned plate face being had by above-mentioned multiple plate-shaped members is formed,
Above-mentioned wind guide component is set as, and other than above-mentioned inflow part, above-mentioned multiple plate-shaped members is had upper
State above-mentioned first area portion's covering detached from each other of plate face.
According to above-mentioned composition, the direction of the direction and the cooling wind flowed into from inflow part of the cooling wind being discharged from outflow portion
It is different.Cooling wind is further suppressed as a result, in the intracorporal irregular movement of shell.
It is also possible to above-mentioned wind guide component to be set as, by other than above-mentioned outflow portion, above-mentioned multiple plate-shaped member institutes
The portion's covering detached from each other of the above-mentioned second area for the above-mentioned plate face having.
According to the difference of configuration mode, light source portion is configured near the side adjacent with the first face.According to above-mentioned
It constitutes, the cooling wind for getting the inside of fin can be taken out in one direction.Outflow portion can be configured as, and with institute of light source portion
The side of the side opposite close to the side of configuration is opposed.
It is also possible to the above-mentioned plate face that above-mentioned multiple plate-shaped members have with above-mentioned first area by multiple above-mentioned second
The mode that region is clamped is formed,
Above-mentioned outflow portion includes set on the first-out part of the position opposed with above-mentioned second face and set on above-mentioned shell
Face and be the side opposite with above-mentioned second face the opposed position in third face second-out part.

Direction towards the second face and the two directions of the direction in third face of the opposite side towards second face are taken out.
The gross area for being also possible to above-mentioned inflow part is the gross area of above-mentioned outflow portion or more.
In order to improve cooling performance and in the case where only increase the size of fin, in order to avoid being detained in the inside of fin
Wind needs to increase the area of the opening portion (outflow portion) of the wind discharge of the inside for will acquire fin.But exists and only lean on
Increase fin, be difficult to obtain opening portion (inflow part) for obtaining from wind to the inside of fin area and above-mentioned outflow portion
This project of the balance of area.
For example, in the case where the composition of above-mentioned Fig. 2, the face of the inflow part 121 for obtaining wind to the inside of fin 103
Product is determined by the set-up mode of wind guide component 105.On the other hand, for will acquire the stream of the wind discharge of the inside of fin 103
The area in portion 122 is determined by the piece number of the multiple fins 103 configured in X direction, the mutual interval of fin 103 of adjoining out.Wing
The length of the Y-direction of piece 103 depends on the size of fin 103.
Assuming that the area of the area ratio outflow portion 122 of inflow part 121 is big, then following problem: the inside of fin 103 can be brought
The wind got be stranded in the inside of fin 103, cause the flow path of cooling wind unstable, cause unnecessary noise.
