A kind of car headlight
Technical field
The utility model relates to automotive lighting field, is specifically related to a kind of car headlight.
Background technology
Automobile front, also claim car headlamp, automobile LED day portable lighter, as the eyes of automobile, be not only related to a car owner's external image, more with driving at night or bad weather condition under safe driving be closely connected.Using and maintaining of car light, can not ignore.Conventionally car headlight is divided into high beam and dipped headlights.High beam can improve sight line, expands field of view.On the pitch-dark road surface that there is no street lamp, the visual range after unlatching high beam will be far longer than only opens dipped headlights.Clear in order to throw light on, conventionally need to use high-powered LED lamp as car headlight.And high-power LED lamp heating is comparatively serious, if can not dispel the heat in time, LED cannot normally open illumination for a long time, also can affect the service life of LED lamp simultaneously.
Utility model content
For the problems referred to above, the utility model aims to provide a kind of good easily changeable car headlight that dispels the heat.
For realizing this technical purpose, the disclosed a kind of car headlight of the utility model, comprise lamp socket, lamp body, between lamp body and lamp socket, be screwed and be connected, on lamp body, be provided with high beam pearl and dipped headlights pearl, high beam pearl and dipped headlights pearl buckle in lamp body fixing by buckle structure, between high beam pearl and dipped headlights pearl, be provided with parallel gapping interval.
As preferably, lamp body lower end is provided with seal chamber, and conduction oil is housed in cavity.
As preferably, high beam pearl and dipped headlights pearl outside are also covered with cylindrical transparent lampshade.
As preferably, lamp body upper end is provided with lid, and lid is fixed on lampshade on lamp body by screw.
As preferably, circular fin is also installed in described lamp socket.
As preferably, described high beam pearl and dipped headlights pearl are high-powered LED lamp.
As preferably, in the middle part of described lamp body, be provided with annular fixing frame.
The beneficial effects of the utility model, lamp socket and lamp body separation design, be screwed connection, very easy demolition and maintenance; In the seal chamber of lamp body below, be marked with conduction oil, can strengthen the radiating efficiency of LED lamp, extend LED service life; The employing of lamp pearl buckles into formula buckle structure and is connected with lamp body, is convenient for changing; Outside lampshade is fixed by lid, very easily changes, and can replace with the lampshade of different colours, makes light color abundanter.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment 1;
Fig. 2 is the structural representation of the utility model embodiment 2.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.
As shown in Figure 1, specific embodiment 1 described in the utility model is a kind of car headlight, comprises lamp socket 1, lamp body 2, between described lamp body 2 and lamp socket 1, be screwed and be connected, lamp socket and lamp body separation design, be screwed connection, very easy demolition and maintenance; On lamp body 2, be provided with high beam pearl 3 and dipped headlights pearl 4, it is interior fixing that high beam pearl 3 and dipped headlights pearl 4 buckle into lamp body 2 by buckle structure, between high beam pearl 3 and dipped headlights pearl 4, is provided with parallel gapping interval.Lamp body 2 lower ends are provided with seal chamber 8, in described cavity 8, conduction oil are housed, and the conduction oil in cavity has good mobility, absorb after the heat in lamp body, are flowed and are made heat take lamp socket to by conduction oil; Then discharge by the fin outside lamp socket and lamp socket.
Interval between high beam pearl and dipped headlights pearl can be so that Air Flow can flow the heat of LED lamp pearl generation timely.High beam pearl and dipped headlights pearl adopt and buckle into formula buckle structure and be arranged in lamp body, dismantle very conveniently, directly extract lamp pearl, without integral demounting.
For guard lamp pearl, can also be covered with cylindrical transparent lampshade 5 on high beam pearl 3 and dipped headlights pearl 4 outsides, lampshade 5 is fixedly connected with lamp body 2.Lampshade can effectively prevent from impacting and water vapor permeable, and lampshade also can be changed color simultaneously, and abundant color is provided.
For the ease of the fixed installation of lampshade, described lamp body 2 upper ends are provided with lid 6, and lid 6 is fixed on lampshade 5 on lamp body 6 by screw.
In the utility model embodiment 2 shown in Fig. 2, in order to improve the integral heat sink efficiency of car headlight, in described lamp socket 1, circular fin 9 is also installed, fin 9 thermal conductivitys are high, can significantly improve radiating effect, the normal use of protection LED lamp pearl.Periphery at circular heatsink 9 is also provided with grid-like aluminum thermal fin, and this peripheral fin can improve radiating efficiency, can be arranged to as required in actual applications different shapes, does not repeat one by one at this.
In order to ensure headlight intensity of illumination, described high beam pearl 3 and dipped headlights pearl 4 are high-powered LED lamp.Single power of high-powered LED lamp is higher, and brightness is brighter, and price is also higher, in order to ensure to use, also needs to coordinate the cooling system that radiating effect is good normally to use for a long time.
For the ease of the fixed installation of headlight, described lamp body 2 middle parts are provided with annular fixing frame 7.Because the screw for separate type between lamp socket and lamp body is fixedly connected with, increase fixed mount can improve the stability of lamp body simultaneously, prevents that use procedure is loosening.
The above; it is only preferred embodiment of the present utility model; not in order to limit the utility model, any trickle amendment that every foundation technical spirit of the present utility model is done above embodiment, be equal to and replace and improve, within all should being included in the protection domain of technical solutions of the utility model.
