Description
Technical field
The present invention relates to a kind of motorcycle LED headlamp.In particular to a kind of motorcycle headlamp radiator structure.
Background technology
In existing motorcycle, conveniently travel night, at headstock, can headlamp be set, and installation code requirement, headlamp needs to have road function and low-beam function.
The headlamp adopted in existing motorcycle, structure is commonly and comprises a lamp housing, and lamp housing front end arranges lens, and lamp housing inside arranges the light structures be made up of components such as lamp pearl and reflectors.Wherein, when lens are arranged, be generally adopt secondary forming mode and forming lens to be integrated lamp housing front section; And then lamp housing front section is connected with main part, like this, although lens position waterproof effect is better, can not intake, but inconvenience installed by lens, lamp housing front section and main part junction do not have waterproof effect, when causing the rainy day to travel simultaneously, rainwater easily enters into lamp housing inside, causes short circuit.
In addition, in existing motorcycle headlamp, light structures, generally overlapping independently lamp pearl and reflector by two completes road function and low-beam function, its volume is larger, take up room larger, electromagnet generally can be adopted simultaneously to become optical mechanism and to change far/dipped beam, make headlamp caloric value large, existing headlamp does not have special radiator structure simultaneously, and radiating effect is poor, causes light structures to be in higher temperature state for a long time, make LED produce light decay phenomenon, and then greatly have impact on LED illumination effect and service life.
Summary of the invention
For above-mentioned the deficiencies in the prior art, technical problem to be solved by this invention is: how to provide a kind of structure simple, the motorcycle headlamp radiator structure of good heat dissipation effect.A kind of motorcycle LED headlamp obtained based on this light structures is provided further, makes it have lens quick and easy for installation, good water-proof effect good heat dissipation effect, the advantages such as long service life.
In order to solve the problems of the technologies described above, present invention employs following technical scheme:
A kind of motorcycle headlamp radiator structure, it is characterized in that, described radiator structure comprises heat radiation bonnet and mount pad, mount pad comprises the pedestal that an entirety is disc rotary, circuit board is provided with in pedestal, it is protruding that pedestal front center has an installation extended to form forward, installs the high beam installed surface that protruding side has a large L shape, install the dipped headlights installed surface that protruding opposite side has a little L shape; Heat radiation bonnet is connected with lamp housing main part and forms lamp housing entirety, heat radiation bonnet and mount pad all adopt aluminium to obtain, described mount pad rear end face has convexed to form some aluminum fin-stock side by side backward, and on mount pad periphery and heat radiation bonnet, the installing rack that extends to form forward contacts.
Radiator structure of the present invention, the heat that lamp pearl and circuit board distribute exports to heat radiation bonnet more easily by mount pad, and after heat radiation, exterior surface contacts with ventilating air, good heat dissipation effect, alleviate light structures due to the overheated light decay phenomenon caused, extend light structures service life.
As optimization, also comprise the two panels fin being fixedly connected on mount pad surrounding position, fin is that aluminium obtains and docks and is connected to form pre-large post-small cone barrel, fin is provided with some louvres and the installing rack that fin and heat radiation bonnet extend to form forward contacts.
Like this, the setting of fin, the surface area of the mount pad that equals to have extended, improve with air contact radiating effect and with heat radiation bonnet contact radiating effect, further increase radiating efficiency.
In sum, structure of the present invention is simple, and has better radiating effect, can alleviate light structures due to the overheated light decay phenomenon caused, and extends light structures service life.
