Description

The shot-light lamp socket

Technical field

The utility model relates to a kind of non-portable electric projection illuminating apparatus that reaches the vehicle front lighting device except that the front lamp of vehicle lighting device, particularly a kind of shot-light lamp socket.

Technical background

The shot-light lamp socket has generally comprised pedestal and cover body, pedestal has and the outside connecting portion that is connected, one end of cover body is connected with pedestal, the other end is open, the bottom of cover body inside has holding part, be used to place luminescence unit (as the LED illuminator) and circuit board, the lead of circuit board penetrates connecting portion and is connected with external power source.Like this, when the luminescence unit that is positioned at cover body inside is luminous, can be used as the part and add the intense light source use, still, because its luminescence unit is the illuminator of high brightness, therefore, also can produce high heat when it is luminous, this high heat distributes speed in lampshade slow, can't distribute timely, thereby cause luminescence unit and circuit board overheated and damage, influence the service life of luminescence unit and circuit board.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of can accelerate that heat distributes speed in the lampshade, prolongs the shot-light lamp socket in service life of luminescence unit and circuit board in the lampshade.

The utility model is realized by following approach.

The shot-light lamp socket comprises pedestal and cover body, and pedestal has and the outside connecting portion that is connected, one end of cover body is connected with pedestal, and the other end is open, and the bottom of cover body inside has holding part, its structural feature is: on cover body, have several holes, this hole be distributed in holding part around.

Around the holding part of cover body bottom, offer some holes like this, thereby increase the area of dissipation of cover body, shot-light is being lighted when producing heat, can accelerate that heat distributes in the lampshade, prolong in the lampshade luminescence unit and circuit board service life.

Structure of the present utility model can be specially:

Described hole or be a kind of perforation perhaps is a kind of blind hole.

Like this, when hole is a kind of blind hole, can increase the area of dissipation of cover body; When hole is a kind of perforation, area of dissipation that not only can cover body, also make the inside and the external environment condition of cover body can produce the air-flow of convection current, thereby shot-light is when lighting the generation heat, cover body inside constantly has extraneous gas to flow into the generation circulation, the heat that accumulates in the cover body can be discharged rapidly by the perforation on the cover body, further accelerate distributing of the interior heat of lampshade.

Pedestal and cover body are Construction integration, and it is by carborundum, alundum (Al, and a kind of ceramic material injection moulding that silica and binding agent mix is one.

Like this, because carborundum has high thermal conductivity, be that main raw material(s) is processed into the shot-light lampshade with carborundum, therefore, this lampshade has the characteristic of good heat dissipation effect.

The surface distributed of cover body outside has the rib of some projectioies.

Like this, form the rib of projection, thereby increase the cover body external surface area, accelerate distributing of cover body surface heat at the cover body outer surface.

Rib or along the axial distribution of cover body and be a kind of strip is perhaps along the circle distribution of cover body and be circular, perhaps along the circle distribution of cover body and be continuous helical form.

Like this, not only can increase the surface area of cover body outside, and form various patterns, also make the outward appearance of lampshade have aesthetic feeling more at the cover body outer surface.

In sum, the utility model has following advantage compared to prior art: a distributive plural hole around the cover body bottom, this hole both can be that blind hole also can be perforation, thereby both can increase the area of dissipation of cover body, help forming the air-flow of convection current again, accelerate the speed that heat distributes in the lampshade, prolong in the lampshade luminescence unit and circuit board service life.

Fig. 2 is the vertical view of Fig. 1.

Wherein, 1 pedestal, 11 connecting portions, 2 cover bodies, 21 holding parts, 22 holes, 23 ribs.

The specific embodiment

Most preferred embodiment:

With reference to Fig. 1, Fig. 2, the shot-light lamp socket, as LED shot-light lamp socket, comprise pedestal 1 and cover body 2, pedestal 1 and cover body 2 are Construction integration, it is by carborundum, alundum (Al, a kind of ceramic material injection moulding that silica and binding agent mix is one, pedestal 1 has and the outside connecting portion 11 that is connected, one end of cover body 2 is connected with pedestal 1, the other end is open, and the bottom of cover body 2 inside has holding part 21, has several holes 22 on cover body 2, this hole is a kind of perforation, and perforation distributions is around holding part 21.The surface distributed of cover body 2 outsides has the rib 23 of some projectioies, and rib 23 is along the axial distribution of cover body and be a kind of strip.

It is same as the prior art that the utility model is not stated part.
