Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
For making the purpose of the embodiment of the present invention, technical scheme and advantage clearer, below in conjunction with accompanying drawing pair
Specific embodiment is described in detail.
As it is shown in figure 1, the street lamp of a kind of high efficiency and heat radiation dedusting that Fig. 1 is the present invention to be proposed, including housing 1,
Substrate 2, heat sink 3, lampshade the 4, first blade the 5, second blade 6, rotating shaft 7, guide shell 13.
Heat sink 3 is arranged in housing 1, and surrounds the first cavity 8 with housing 1, and substrate 2 is arranged on heat radiation
Plate 3 has with the first cavity 8 even away from the side of heat sink 3 away from the side of the first cavity 8, substrate 2
The first logical hole 9, the first hole 9 is blind hole；The sidewall in the first hole 9 is provided with second connected with extraneous air
Hole 10, the second hole 10 is through hole；Substrate 2 is provided with multiple lamp bead 11 away from the side of heat sink 3.Substrate 2
Lower end be pyramidal structure, i.e. substrate 2 is pyramidal structure away from the side of heat sink 3.So, it is possible to increase
The lighting angle of street lamp.
The one end open direction that second hole 10 connects with extraneous air is obliquely.So, can prevent when the rainy day,
Rainwater enters in housing.The quantity in the second hole 10 is multiple, and uniformly divides along the circumferencial direction in the first hole 9
Cloth.
Lampshade 4 is arranged on the housing 1 side near substrate 2, and substrate 2 and lamp bead 11 are respectively positioned on lampshade 4
In, light-passing board 12 is installed in lampshade 4, and light-passing board 12 is positioned at the substrate 2 side away from heat sink 3.
Light-passing board 12 is concavees lens.So, it is possible to increase the lighting angle of street lamp.
Rotating shaft 7 passes and may be rotatably mounted at the housing 1 side away from heat sink 3, its centrage and first
The centrage in hole 9 overlaps, and rotating shaft 7 first end is positioned at the first cavity 8, and it is outside that the second end is positioned at housing 1,
Multiple first blades 5 are arranged on the first end of rotating shaft 7, and multiple second blades 6 are arranged on the second of rotating shaft 7
End.Second blade 6 is spherical calotte structure, and the side for plane has groove structure.So, can make
The active force that wind-force produces on different blades is different such that it is able to produces rotating torque, and drives rotating shaft
Rotate, so that the first blade rotates and produces air-flow in housing, thus the heat on heat sink is taken out of
Housing.The surface area of the second blade 6 more than the surface area of the first blade 5, and the quantity of the first blade 5 with
The quantity of the second blade 6 is equal.
The sidewall of lampshade 4 is provided with C-shaped through hole, and the two-port of this through hole is separately positioned on the two of light-passing board 12
Side, the first end and first cavity 8 of this through hole connect, the second oblique top, end opening direction of this through hole.
So, the lateral surface of light-passing board 12 can be formed air-flow, thus light-passing board 12 is carried out dedusting.
In present embodiment, guide shell 13 is arranged on housing 1 and its axis and the centrage weight in the first hole 9
Closing, the diameter of guide shell 13 is more than the diameter in the first hole 9.So, the side of air-flow in housing 1 can be improved
Tropism, prevents the generation of turbulent flow phenomenon, is conducive to improving air velocity, it is possible to accelerate heat radiation.
The above, the only present invention preferably detailed description of the invention, but protection scope of the present invention not office
