In view of this, Chinese patent 201420012339.9 proposes a kind of LED car lamp, comprise housing, be installed on lampshade on front side of housing, lamp socket and pcb board is provided with in described housing, described lamp socket is provided with a LED and a prefocus cup, described lamp socket is provided with threaded connection hole, and described LED is fixedly connected on described lamp socket by screw; The side edge of described housing is along being provided with annular groove, and the bottom of described lampshade is provided with the annular boss to downward-extension, and described annular boss is arranged in annular groove.In the utility model, LED is fixedly installed on the inside of housing by screw, and only uses the corresponding prefocus cup of single LED lamp, makes light source more demonstrate the characteristic of spot light, improves spotlight effect, energy-saving and environment friendly.But it exists following problem: 1. radiating effect is poor, have impact on the life-span of LED car lamp; 2. dust easily enters into lamp chamber, impacts the reflectivity of LED car lamp and light transmittance.
Utility model content
Problem to be solved in the utility model is to provide a kind of good heat dissipation effect, can prevents dust from entering into the high-power LED car light in lamp chamber, and the utility model can be base and prefocus cup heat radiation simultaneously, extends service life.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of high-power LED car light, comprise housing, lamp socket, prefocus cup and the lampshade be installed on front side of housing, described lamp socket is arranged on the rear side of described housing, described prefocus cup is arranged on described lamp socket, described lamp socket is provided with LED group, it is characterized in that: the sealing ring being provided with flat between described prefocus cup and described lamp socket, the bottom of described lamp socket is provided with some fin, described lamp socket is connected with heat exchanger by radiating tube, described heat exchanger is connected with radiating subassembly, described radiating subassembly is a spiral fashion metal tube, heat-conducting medium is sealed with in described heat exchanger and radiating subassembly, described lamp socket is provided with at least one radiator fan between described housing, prefocus cup.
Preferably, above-mentioned high-power LED car light, wherein said spiral fashion metal tube is formed by connecting by many steel pipe head and the tail.
Preferably, above-mentioned high-power LED car light, the quantity of wherein said radiator fan is two.
Preferably, above-mentioned high-power LED car light, wherein said heat-conducting medium is acetone, ethanol or pure water.
Preferably, above-mentioned high-power LED car light, wherein said sealing ring adopts silicon rubber to be prepared from.
