Description
Technical field
The utility model relates to a kind of light fixture, particularly relates to a kind of LED street lamp.
Background technology
Street lamp is the important component part of city illumination, along with the development of semi-conducting material industry, LED is using light emitting diode as light source, because it is a kind of solid-state cold light source, there is the features such as environment friendly and pollution-free, little power consumption, light efficiency are high, the life-span is long, therefore be gradually widely used in every field, especially gain great popularity at lighting field in LED street lamp.The advantages such as LED street lamp is low with directional lighting, power consumption, fast response time, environmental protection pour in the visual field of people, become the energy-conserving light source of a new generation.
LED belongs to semi-conducting material, and temperature affects the size of its luminous flux and concerns the length in its life-span, so the thermal diffusivity of LED is very important.The radiating mode of LED street lamp mainly contains: Natural Heat Convection, install fan forced heat radiation, heat pipe and loop heat pipe heat radiation etc. additional.The system installing fan forced heat radiation mode additional is more complicated, reliability is low, heat pipe and loop heat pipe radiating mode cost higher.The exploitation of the LED street lamp that therefore a kind of radiating mode is simple, reliability is high, heat radiation cost is low is necessary.
Utility model content
Utility model object: technical problem to be solved in the utility model is to provide that a kind of structure is simple, the LED street lamp of good heat dissipation effect, long service life, and this LED street lamp radiating mode is simple, reliability is high, heat radiation cost is low.
Utility model content: for solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of LED street lamp, comprise stainless steel protective cover, described protective cover and lamp stand connecting portion one-body molded, described protective cover encloses a closed cavity by the copper base plate of bottom, described base plate is provided with limitting casing and louvre, described lamp plate is fixed in described limitting casing, described louvre is positioned at the side of described lamp plate, described lamp plate is provided with multiple LED light source, multiple described LED light source is matrix form arrangement, be coated with thermal conductive silicon lipid layer outside described stainless steel protective cover, the thickness of described thermal conductive silicon lipid layer is 2 ~ 3mm.
Further preferably, described stainless steel protective cover is arranged in waiting octagon.
Further preferably, the cross section semicircular in shape of described stainless steel protective cover.
Further preferably, to having radiator structure in described louvre, described radiator structure comprises radiating fin and heat-radiating substrate, and described heat-radiating substrate contacts with the light source in described cavity, and described radiating fin equidistant vertical is placed on described heat-radiating substrate.
Beneficial effect: compared to prior art, the utility model LED street lamp protective cover surface area is large, be conducive to the natural convection air heat radiation of whole LED, the thermal conductive silicon lipid layer with high thermal conductivity and splendid thermal conductivity is coated with in addition outside protective cover, therefore further effectively improve radiating effect and the radiating efficiency of the utility model LED, the utility model LED street lamp structure be simple, good heat dissipation effect, long service life.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model LED street lamp;
Fig. 2 is the top view of the utility model LED street lamp.
Detailed description of the invention
According to following embodiment, the utility model can be understood better.But those skilled in the art will readily understand, the content described by embodiment only for illustration of the utility model, and should can not limit the utility model described in detail in claims yet.
Composition graphs 1 ~ 2, LED street lamp of the present utility model, comprise stainless steel protective cover 1, protective cover 1 is one-body molded with lamp stand connecting portion 2, protective cover 1 encloses a closed cavity by the copper base plate 3 of bottom, base plate 3 is provided with two limitting casings be arranged side by side and two louvres 4, lamp plate 5 is fixed in limitting casing, two louvres 4 are separately positioned on the both sides of lamp plate 5, lamp plate 5 is provided with multiple LED light source 6, the arrangement in matrix form of multiple LED light source 6, be coated with thermal conductive silicon lipid layer 7 outside stainless steel protective cover 1, the thickness of thermal conductive silicon lipid layer 7 is 2 ~ 3mm.
The utility model LED street lamp improves radiating efficiency by the external surface area improving protective cover 1, enormously simplify the radiating mode of LED street lamp, also reduce the heat radiation cost of LED street lamp, the utility model LED street lamp protective cover 1 is arranged in waiting octagon, and its cross section approximate half-circular is arranged (external surface area of half-round shield is greater than the external surface area of the protective cover that plane is arranged), thus considerably increase the external surface area of protective cover 1, the increase of protective cover 1 external surface area is conducive to the cooling surface area increasing whole LED street lamp, thus improve the radiating efficiency of whole LED street lamp, in addition, owing to being coated with the thermal conductive silicon lipid layer with high thermal conductivity and splendid thermal conductivity outside protective cover 1, therefore further effectively improve the radiating effect of the utility model LED street lamp.
In the louvre 4 of the utility model LED street lamp, also correspondence is provided with radiator structure, and radiator structure comprises radiating fin and heat-radiating substrate, and heat-radiating substrate contacts with the light source in cavity, and radiating fin equidistant vertical is placed on heat-radiating substrate.
