Preferably, described lamp socket bottom surface radial direction is provided with the radiating groove of more than 2, and radiating groove extends to the outer wall of lamp socket.
Preferably, described lamp socket holder outer wall is provided with vertically through heat dissipation channel.
Preferably, described LED lamp source is the end face that round is distributed in lamp socket, and often circle comprises the LED lamp source of more than 4.
Preferably, described lamp socket end face is provided with conical round table, and the end face circumference of conical round table is distributed with LED lamp source, and the side of conical round table is evenly distributed with LED lamp source.
Preferably, the side of described lampshade is provided with rib, and described section of ribs is semicircle.
After adopting the technical program, base is fixedly connected with lamp socket holder, during installation, lamp socket is pulled down temporarily, base and ceiling or metope are directly fixed, then by lamp socket by fast assembling disassembling structure and the clamping of lamp socket holder, reach Fast Installation, the effect of dismounting, the end face of lampshade is provided with 2 with upper section is in addition semicircular annular ring, annular ring can increase the surface area of lampshade first, thus increase the area of dissipation of lampshade, secondly many annular rings are equivalent to the reinforcement being located at cover surface, the surface strength of lampshade can be increased, prevent the too high generation cracking of temperature, last annular ring cross section is semicircle, for LED lamp source increases the refraction effect of multi-angle, make illumination range wider.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further:
As shown in Figures 1 to 4, a kind of LED projection lamp, comprise base 4, LED lamp source 5 and lampshade 1, base in this programme, lampshade appearance profile is all circular, described base internal fixtion is provided with lamp socket holder 3, lamp socket holder comes to realize with base fixing by placing screws in 4 screw-threaded counterbore on surface, lamp socket holder is connected with lamp socket 2 by fast assembling disassembling structure, namely can quick-detachment or installation between lamp socket and lamp socket holder, described LED lamp source 5 is located on lamp socket end face, described lampshade is fixed on above lamp socket, it is semicircular annular ring 11 that the end face of lampshade is provided with 2 with upper section.After adopting the technical program, base is fixedly connected with lamp socket holder, during installation, lamp socket is pulled down temporarily, base and ceiling or metope are directly fixed, then by lamp socket by fast assembling disassembling structure and the clamping of lamp socket holder, reach Fast Installation, the effect of dismounting, the end face of lampshade is provided with 2 with upper section is in addition semicircular annular ring, annular ring can increase the surface area of lampshade first, thus increase area of dissipation, secondly the surface strength of lampshade is increased, prevent the too high cracking of temperature, last annular ring cross section is semicircle, for LED lamp source increases refraction effect, in this programme, LED lamp source is provided with many, coordinate many annular rings, light-dispersing effect is better, make illumination range wider.
Composition graphs 2 to Fig. 4 is known, described lamp socket and lamp socket holder are cylindrical, described fast assembling disassembling structure comprises two long slot bores 31 being located at lamp socket holder upper surface, long slot bore is spliced by circular hole and mounting hole and forms, the diameter of circular hole is larger than the width of mounting hole, described lamp socket bottom surface is provided with inserts long slot bore and the metallic pin 21 connecting circuit, the diameter of metallic pin mates with the width of mounting hole, during installation, metallic pin is aimed at circular hole, the diameter of circular hole is larger than the diameter of metallic pin, insert than being easier to, after aligning, lamp socket is rotated to an angle, allow metallic pin slip in mounting hole and realize clamping, when metallic pin slides in mounting hole in addition, meeting and the circuit board diameter contact be arranged in lamp socket holder, thus connection circuit, can throw light on after LED lamp source energising on lamp socket.In order to increase the degree of being connected firmly up and down of fast assembling disassembling structure, described lamp socket bottom center is provided with round platform 22, lamp socket holder center is provided with the endoporus 32 holding round platform 22, endoporus inwall is provided with two projections 321, the outer wall of round platform is provided with two L-type chutes 221 of locating convex block, when metallic pin aims at long slot bore, two projections also targeted by the vertical slideway of L-type chute simultaneously, after lamp socket is pressed, projection slides into the highest position of vertical slideway, when metallic pin turn an angle slide in mounting hole time, projection is also in the corresponding transverse slipway sliding into L-type chute, thus ensure fixing of lamp socket and lamp socket holder vertical direction, prevent lamp socket from departing from lamp socket holder, eliminate the step be screwed, really realize quick-detachment, install.
The caloric value of LED is larger, in order to increase the radiating effect of whole LED, described lamp socket bottom surface radial direction is provided with the radiating groove 23 of more than 2, radiating groove extends to the outer wall of lamp socket, in addition, described lamp socket holder outer wall is provided with vertically through heat dissipation channel 33, such heat can come out from the radiating groove between lamp socket and lamp socket holder, continuing to distribute outward from the outer wall of lamp socket holder when being dispersed into lamp socket outer wall, finally be provided with louvre 13 the outer wall of base is also corresponding, heat carries out heat exchange eventually through louvre and the external world.
In order to increase the illuminating effect of LED multi-angle, described LED lamp source is the end face that round is distributed in lamp socket, and often circle comprises the LED lamp source of more than 4, and the LED lamp source of multi-turn structure distribution coordinates multi-ring annular circle, and illuminating effect can be allowed better.
As shown in Figure 5, for the embodiment schematic diagram of another kind of lamp socket, be that lamp socket end face is provided with conical round table 24 with the difference of upper a kind of embodiment, the end face circumference of conical round table is distributed with LED lamp source, the side of conical round table is evenly distributed with LED lamp source, compared with embodiment, advantage is the third dimension increasing illumination, and conical outer wall is also provided with the lighting effect of LED lamp source increase to side, more expand lighting angle and the illumination range of whole LED, the side of lampshade described is in addition provided with many ribs 12, rib is evenly distributed in the peripheral side of lampshade, described section of ribs is semicircle, rib and annular ring have similar effect, the surface strength of lampshade can be increased first, cooling surface area can also be increased, key coordinates the LED lamp source on conical outer wall, for the LED lamp source of side increases light-dispersing effect.
Below only with regard to the utility model preferably example be described, but can not be interpreted as it is limitations on claims.The utility model not only limits to and above example, its concrete structure allows to change, those skilled in the art can make various change and distortion according to the utility model, only otherwise depart from spirit of the present utility model, all should belong to the scope that the utility model claims define.
