Description
Technical field
This utility model relates to electronic technology field, particularly relates to a kind of LED automobile headlamp.
Background technology
Now widely used headlight for vehicles is Halogen light, and due to its light efficiency extremely low (18LM-23LM/W), high beam irradiates
Apart from limited, thus when visibility is poor or speed is higher, (>=80 kilometers/hour) have seemed not competent, easily cause
Vehicle accident.To have energy-saving and environmental protection, life-span long because of it for LED (Light Emitting Diode, light emitting diode) headlight for vehicles
Feature, and be not susceptible to vibration effect, during use, light output brightness also will not be decreased obviously, and uses LED as vapour
Car headlight is just becoming the development trend of industry.But the use condition of headlight for vehicles is harsh, its light-emitting area is little, and power is big, work
Make environmental condition poor (high temperature, the crawl space of relative closure, vibrations, dust and greasy dirt etc.), how LED automobile headlamp is carried out
Heat radiation is a difficult problem in the industry always.The existing commonly used electric fan of LED automobile headlamp heat sink conception carries out forced heat radiation, not only
Need to additionally install fan additional, increase power consumption, and radiating effect and reliability, stability are the most unsatisfactory.
Utility model content
The purpose of this utility model embodiment is to provide a kind of LED automobile headlamp, improves LED automobile headlamp thermal diffusivity
Energy.
To achieve these goals, this utility model embodiment provides a kind of LED automobile headlamp, including lamp stand and fin
Radiator；
Being provided with LED light source component on described lamp stand, described lamp stand is internally provided with heat pipe, described LED light source component
Being mounted on described heat pipe, described heat pipe is connected with described fin slices radiator.
Preferably, described lamp stand is additionally provided with reflector；Described LED light source component is installed in described reflector.
Preferably, described lamp stand is additionally provided with dismountable installed cassette.

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
See Fig. 1, be the structural representation of an embodiment of the LED automobile headlamp that this utility model provides.
As it is shown in figure 1, described LED automobile headlamp includes lamp stand 11 and fin slices radiator 12.
Being provided with LED light source component 111 on described lamp stand 11, described lamp stand 11 is internally provided with heat pipe and (does not draws in figure
Go out), described LED light source component 111 is mounted on described heat pipe, and described heat pipe is connected with described fin slices radiator 12.
Described lamp stand is preferably aluminium alloy lamp stand, can accelerate distributing and transmitting of heat by aluminium alloy lamp stand.
As in figure 2 it is shown, in the middle of a kind of embodiment preferably, the middle part of described fin slices radiator 12 is heat conduction
The fin being externally connected to uniformly arrange of rosette or annulus, described disk or annulus, described fin and with its phase
The circular arc connect is mutually perpendicular to, and to increase heat exchange area, and forms the vertical and horizontal passage of heat.
It is heat dissipation problem that LED automobile headlamp needs most the problem of solution, and this utility model is by using heat pipe by LED light
The heat that source device produces imports in the heat exchange area fin slices radiator that greatly, vertically and horizontally passage thermal impedance is low the most rapidly,
It is greatly improved the reliability of LED automobile headlamp, stability and life-span (>=25000 hours).
Preferred embodiment central in one, described lamp stand 11 is the cylinder of diameter 19mm, described fin slices radiator
12 is also cylindrical, and the diameter of described fin slices radiator 12 is preferably 46mm.
For making full use of luminous energy, control luminous range and the illuminating area of LED light source component 111, on described lamp stand 11 also
It is provided with reflector 112.Described LED light source component 111 is installed in described reflector 112.Described reflector 112 is preferably true
Empty coated reflective cup.More excellent, the vacuum coating reflector of high reflectance can be used.This utility model is by reflective reflective
Cup, reflected light projects is more accurate, the brightest farther (brightness ratio conventional halogen lamp improves 40%, and irradiation distance improves 30%, distance light by
Originally 110 meters bring up to 145 meters), it is the preferable regeneration product of conventional halogen headlight for vehicles.
Further, described lamp stand 11 is additionally provided with dismountable installed cassette 113.Described installed cassette 113 is used for
The installation of LED automobile headlamp and fixing, can be by rotating (around described lamp stand clockwise or counterclockwise) and forward from lamp stand
Dismounting is released in the front end of 11.The installed cassette of existing headlight for vehicles is the most non-dismountable, if original with automobile when mounted
Dust-proof deck does not mates, then needing to change former on automobile has preventing dust water jacket.This utility model is pacified by the headlight of dismountable type
Be installed seat, when changing or reequip car light, can first be disassembled by installed cassette, will install after headlight is put into dust-proof deck again
Deck reinstalls, and can retain the use of original preventing dust water jacket on automobile.
