Illustrate the stream of the gases such as the air from cooling fan 80 to the lamp unit 10 being made of above such structure
It moves, and more detailed structure is illustrated.
If driving cooling fan 80, the gases such as air are blowed to fin part 45.
Specifically, if observing Fig. 3 it is found that cooling fan 80 be configured to vertical fin part 46 and horizontal fin part 48 this
Two sides blow wind, and a part of the wind generated by cooling fan 80 is blowed towards horizontal fin part 48.
It blows to the wind of the horizontal fin part 48 and passes through between multiple horizontal fin pieces 49 of arrangement in the longitudinal direction, draw on one side
The heat of horizontal fin piece 49 is flowed towards upside on one side, blows to the back side of the part configured with first light source portion 20 of horizontal part 42.
Also, the back side extract water of the one edge horizontal part 42 of wind of flowing to the upper side is limited by the back side of horizontal part 42
The heat in flat portion 42 further flows in the horizontal direction on one side, and releases to the outside of the left and right directions of radiator 40.
In addition, the flowing in order not to hinder the gas (air etc.) from cooling fan 80, it is important that efficiency is well
Wind is released from radiator 40.
However, in recent years, it is desirable that the miniaturization of lamps apparatus for vehicle especially requires to minimize in the front-back direction.
Therefore, there is the tendency of rear side of the wall surface for the shell for forming lamp house close to lamp unit 10, if therefore with this
The horizontal fin piece 49 of horizontal fin part 48 releases wind as longitudinal wings piece rearward, then can not efficiency release wind well.
On the other hand, since the space for releasing wind can be obtained in the lateral direction, such as present embodiment that
Sample, by making the rear side of radiator 40 become the horizontal fin part 48 of arrangement horizontal fin piece 49 in the longitudinal direction, so as to not
Hinder the releasing of wind.
Therefore, the flowing for flowing the wind between horizontal fin piece 49 can be made good, thus allow for first light source portion 20
Effective cooling.
On the other hand, as described above, the front side of radiator 40 is vertical as being arranged on (left and right directions) in the horizontal direction
The vertical fin part 46 of fin 47.
The vertical fin part 46 is by forming longitudinal wings piece 47 and extension rearward from the back side of rake 43, wherein should
Rake 43 extends from the front side of horizontal part 42 to the downside of diagonally forward.
Therefore, blowing to a part of the wind of vertical fin part 46 will not be hindered by fin, along from the back side of rake 43
The inclination of downside towards upside and rearward is flowed while rear-face contact with rake 43.
In addition, in the case where being set to fin herein is horizontal fin piece, due to being led to the left and right by horizontal fin piece, nothing
Method is flowed towards upside.
Especially, the back side of rake 43 is different from vertical plane and tilt, therefore efficiency contacts wind well, so as to
Obtain higher exothermal efficiency.
Also, as shown in Figure 3 and 4, in the horizontal part 42 of base portion 41, to include position corresponding with vertical fin part 46
The mode set, equipped with the opening portion 44 that gas can be made to circulate from back side side to surface side, towards upside flowing in stream longitudinal wings piece
A part of the wind in portion 46 is flowed out by the opening portion 44 to the upside of radiator 40.
As described above, the position between first light source portion 20 and second light source portion 30 is arranged in the opening portion 44, from opening
The heat seal in these light source portions (first light source portion 20 and second light source portion 30) of wind direction that portion 44 is flowed out gets up and easily becomes height
The part blowout of temperature, thus, it is possible to obtain high cooling efficiency.
Further, since between being formed and misunderstanding each other between longitudinal wings piece 47 and horizontal fin part 48, therefore flow in not setting vertical fin part
Gas between the longitudinal wings piece 47 of the part of 46 opening portion 44 will not hinder to flow, but pass through longitudinal wings piece 47 and horizontal fin piece
It is flowed out between gap between portion 48 to the horizontal side of horizontal direction, the flowing of wind will not stop.
In the present embodiment, as shown in figure 3, being equipped with lampshade 70 on opening portion 44, from the flow direction of cooling fan 80
The flow direction for the gas that the mode of side is blown out by lampshade 70 guide to horizontal direction (be viewed as in Fig. 3 left direction and
Right direction), therefore at least part of the gas flowed out from opening portion 44 is directed to lens 50 and second light source portion 30
At least one of side, the gas flowed out from opening portion 44 is directed to 20 side of first light source portion.
It therefore, inside can be with first light source portion 20 and second comprising being easy to become because of radiant heat the lens 50 of high temperature
Light source portion 30 cools down together.
But lampshade 70 needs not be on opening portion 44.
As long as example, making second light source portion 30 slightly within downside and up to a part of the upside of rake 43 is arranged
It opening portion 44 can also be with since a part of the gas flowed out from opening portion 44 can be made to flow out towards front side
Until a part setting opening portion 44 of the upside of rake 43, to replace the upside for making lampshade 70 be located at opening portion 44.
In addition it is also possible in the state of making lampshade 70 be located at the upside of opening portion 44, until the upside of rake 43
A part setting opening portion 44.
In this way, if the gas flowed out from opening portion 44 also causes gas near second light source portion 30 towards front side
The flowing of body, therefore more efficiency second light source portion 30 can be cooled down well.
In addition, if observing Fig. 3 it is found that vertical fin part 46 80 side of cooling fan broadens due to rake 43, and towards upper
Side narrows, therefore efficiency accesses the wind from cooling fan 80 well, and the flow velocity of wind becomes faster towards upside, is easy from opening portion
44 blow out fiercely.
Therefore, can efficiency well to 50 side of lens and the side-blown air-supply in first light source portion 20, and towards lens 50
The side-blown gas sent and lampshade 70 are mutually auxiliary the case where also extending in second light source portion 30, unhorizontal in the front side of lampshade 70
Portion 42 limits, and flows in a manner of to the extension of 30 side of second light source portion therewith, so that efficiency cools down second light source portion 30 well.
In addition, if making the flow direction front side of the gas flowed out from opening portion 44, towards 20 side of first light source portion
The flowing of gas declines, but as in the present embodiment, is being provided with than the second of the more luminescence chips in first light source portion 20
In the case where light source portion 30, since the fever quantitative change in second light source portion 30 is more, if considering whole cooling efficiency, preferably
Make the flow direction front side of the gas flowed out from opening portion 44.
(variation of radiator 40)
