Description
Technical field
The utility model relates to automobile lamp technical fields, more particularly, to a kind of LED automobile headlight.
Background technique
Lamps and lanterns space becomes small at present, moulding be also it is increasingly exquisiter, cause many lamps and lanterns in order to meet modeling requirement,
It is realized using LED.
LED will have heat dissipation, need very big heat-dissipating space if lamps and lanterns are using passive heat radiation, simultaneously
Since heat radiating material is commonly aluminium and copper material, the wind that falls off for also increasing the lamps and lanterns later period will increase to the weight of lamps and lanterns itself
Danger；And existing lamps and lanterns are mostly using passive type exhaust structure, are not highly desirable to the fog solution at lamp interior dead angle.
Utility model content
In view of the shortcomings of the prior art, the technical problem to be solved by the utility model is to provide a kind of LED automobile headlight, with
Reach high efficiency and heat radiation, and can effectively solve the purpose that fog generates in lamps and lanterns.
In order to solve the above-mentioned technical problem, the technology employed by the present utility model is
The LED automobile headlight, including lamp housing and the LED light source being located in lamp housing and the reflection being located above LED light source
Bowl further includes heat sink and for the fan to heat sink quenching, and the LED light source is located on heat sink, the fan
The lower section of heat sink is located in lamp housing.
Further, the heat sink is aluminium sheet, and corresponds to fan side on heat sink and be equipped with heat dissipation convex ribs.
The heat sink is arranged to lamp housing back sweep.
The heat sink is equipped with ventilation hole.
Gap is all had between at the top of the reverberation bowl and lamp housing and between fan and lamp housing bottom.
The lamp housing includes lamp body and the mask that is located on lamp body, is equipped with adornment frame by mask in lamp body, and fan is located at dress
The rear of escutcheon.
Optical module, the optical module, heat sink, reflection are equipped in the front of heat sink and reverberation bowl in the lamp housing
It is set together between bowl and fan by fixed integrate of buckle structure and/or fastener.
The heat sink is frame plate structure.
There is gap on the inside of the inward flange of the optical module and adornment frame.
The utility model compared with prior art, has the advantage that
The LED automobile headlight is reasonable in design, and active heat dissipation efficiently, can effectively reduce lamp cooling structure in lamps and lanterns
And mitigating lamps and lanterns weight, the active air flowing for increasing lamp interior by force can effectively solve lamp interior fog
It generates；And structure is simple, convenient for arrangement installation.
Detailed description of the invention
Content expressed by each width attached drawing of this specification and the label in figure are briefly described below:
Fig. 1 is the utility model automobile headlamp principle sketch.
Fig. 2 is the utility model automobile headlamp schematic cross-section.
Fig. 3 is air circulation schematic diagram in the utility model lamp.
In figure:
1. reverberation bowl, 2.LED light source, 3. heat sinks, 4. fans, 5. distance-light switching constructions, 6. optical modules, 7. lamps
Body, 8. masks, 9. adornment frames.
Specific embodiment
Below against attached drawing, by the description of the embodiment, making to specific embodiment of the present utility model further detailed
Thin explanation.
As shown in Figure 1 to Figure 3, the LED automobile headlight including lamp housing, the LED light source being located in lamp housing 2 and is located at LED
The reverberation bowl 1 of the top of light source 2, heat sink 3 and for the fan 4 to heat sink quenching.
LED light source is located on heat sink 3, and fan 4 is located at the lower section that heat sink 3 is located in lamp housing；Reverberation bowl 1 and lamp housing top
Gap is all had between portion and between fan 4 and lamp housing bottom.Active heat dissipation efficiently, can effectively reduce lamps and lanterns and dissipate in lamps and lanterns
Heat structure and mitigation lamps and lanterns weight, the active air flowing for increasing lamp interior by force, can effectively solve lamp interior
The generation of fog.
Heat sink 3 is arranged to lamp housing back sweep, it is ensured that LED light source light is sufficiently radiated on reverberation bowl；In lamp housing
Optical module 6, optical module 6, heat sink 3, reverberation bowl 1, distance-light switching construction 5 are equipped in the front of heat sink and reverberation bowl
And it is set together between fan 4 by fixed integrate of buckle structure and/or fastener；It is compact-sized, it is easily installed operation.
Heat sink 3 is frame plate structure, and heat sink is aluminium sheet, and corresponds to fan side on heat sink and be equipped with heat dissipation convex ribs,
Heat sink is equipped with ventilation hole.Efficiently, active heat dissipation solves lamp interior space and own wt for active heat dissipation in lamps and lanterns
Problem.
Lamp housing includes lamp body 7 and the mask 8 that is located on lamp body 7, is equipped with adornment frame 9 by mask in lamp body, and fan is located at dress
The rear of escutcheon；There is gap on the inside of the inward flange of optical module and adornment frame.Active increase lamp interior air flowing subtracts
The generation of few lamps and lanterns fog, actively increases lamp interior air circulation, reduces the case where lamps and lanterns dead angle generates fog.
It above are only and preferred embodiments of the present invention are illustrated, above-mentioned technical characteristic can form multiple hairs in any combination
Bright example scheme.
The utility model is exemplarily described above in conjunction with attached drawing, it is clear that the utility model specific implementation not by
The limitation of aforesaid way, as long as the improvement for the various unsubstantialities that the conception and technical scheme for using the utility model carry out,
Or it is not improved the conception and technical scheme of the utility model are directly applied into other occasions, in the guarantor of the utility model
Within the scope of shield.
