Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
In figure: pedestal -1, the first lampshade -2, heat sink -3, substrate -4, the second lampshade -5, diversion pipe -6, the first blade - 7, the second blade -8, shaft -9, lamp bead -10, rain cover -11, strut -12, the first hole -101, third hole -102, the second hole - 301, thermal column -302.
Specific embodiment
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is the structural schematic diagram of Lawn lamp of the invention, and wherein the Lawn lamp includes pedestal 1, the first lampshade 2, heat dissipation Plate 3, substrate 4, the second lampshade 5, diversion pipe 6, the first blade 7, the second blade 8, shaft 9, rain cover 11 and strut 12.
First lampshade 2, the second lampshade 5 and substrate 4 are installed on pedestal 1, and the second lampshade 5 is located in the first lampshade 2, Substrate 4 is located in the second lampshade 5, and substrate 4 is tubular construction, and the diameter at 4 both ends of substrate is greater than middle section when specific implementation Diameter, lamp bead 10 gradually become smaller along directional spreding density of the substrate 4 from centre to both ends, are so conducive to pass through substrate in air-flow It is generated when 4 and is close to the vortex that substrate 4 moves, to take away more heats.Multiple lamp beads 10 are installed on 4 periphery of substrate.
The first end of diversion pipe 6 is connect with the second lampshade 5 far from one end of pedestal；It is remote that heat sink 3 is mounted on the first lampshade 2 One end from pedestal 1, and connect with the second end of diversion pipe 6, form the first air duct and the second air duct, the first air Channel is surrounded by 2 inner wall of the first lampshade, 6 periphery of diversion pipe and 5 periphery of the second lampshade, the second air duct by 6 inner wall of diversion pipe, Second lampshade, 5 inner wall and substrate 4 surround.
Pedestal 1 is equipped with the first hole 101 that multiple center lines are C-shaped, and the first hole 101 and the first air duct, second Air duct is connected to.When it is implemented, diameter of first hole 101 from centre to both ends becomes larger.Heat sink 3 is close to first The side of lampshade 2 is equipped with the second hole 301 that multiple center lines are C-shaped, and the second hole 301 and the first air duct, the second air Channel is connected to, and forms annular air-flow path；When it is implemented, heat sink 3 is equipped with multiple thermal columns 302, thermal column 302 It is evenly distributed on side of the heat sink 3 far from the first lampshade 2.In this way, increasing heat dissipation area, wind is blown over from 3 surface of heat sink When, more heats can be taken away, to improve radiating efficiency.
In present embodiment, third hole 102, the first hole 101, base on third hole 102 and pedestal 1 are additionally provided on pedestal 1 Space between plate 4 and the second lampshade 5 is connected to.It so, it is possible to guarantee that steam flow passes through from the inner wall of substrate 4 and periphery, from base The inner wall of plate 4 and periphery radiate to it, are conducive to improve radiating efficiency.
Shaft 9 may be rotatably mounted on heat sink 3, and first end passes through heat sink 3 and is located in diversion pipe 6, shaft 9 the Two ends are located at side of the heat sink 3 far from the first lampshade 2；Multiple first blades 7 are mounted on the first end of shaft 9, and multiple second Blade 8 is mounted on the second end of shaft 9.First blade 7 is equal with the quantity of the second blade and the surface area of the first blade 7 is less than The surface area of second blade 8.When it is implemented, the second blade 8 is spherical calotte structure, and has groove knot for the side of plane Structure.So, it is ensured that the side of the second blade 8 has groove, and the other side has smooth structure, thus guarantee when blowing air over, Power suffered by second blade 8 is different, generates rotating torque and drives the rotation of the first blade 7.
In present embodiment, 12 first end of strut is mounted on side of the heat sink 3 far from the first lampshade 2, and multiple struts The distribution of 12 circular arrays, rain cover 11 are connect with the second end of strut 12.When it is implemented, rain cover 11 has taper knot Structure.In this way, shaft 9 can be prevented by rain erosion, pyramidal structure is conducive to that rainwater is discharged in time.
In present embodiment, 3 periphery of heat sink is equipped with thermal insulation layer 13.Due to heat sink 3 during heat dissipation temperature liter Height, to artificial at scald and preventing that the circumferential temperature of heat sink 3 is excessively high in thermal insulation layer 13.Make the radiating surface collection of heat sink 3 In in upper surface.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any to repair Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
