Abstract
The utility model relates to a radiating shell of an LED illuminating street lamp, comprising a body and radiating fins. The radiating fins are downward arranged at the lower part of the body; the upper surface of the body forms an arc (11); the body and the radiating fins are integrated; by adopting the technical proposal, as the radiating fins are downward arranged, dirt can be prevented from being deposited effectively, the radiating effect can be guaranteed and the working performance and the service life of the street lamp can be improved; in addition, the upper surface of the body forms the arc, so the rain and dust can flow down along the arc surface, thus being capable of effectively preventing the dirt from depositing; and as the body and the radiating fins are integrated, the whole radiating area is large and the radiating effect is better.
Description
Technical field:
The utility model belongs to the illumination series of products, especially can prevent rainwater, dust deposit with a kind of, and radiating effect is better, and the road LED illuminating street lamp heat-dissipating casing of safety, energy-conserving and environment-protective is relevant.
Background technology:
Present LED large power road lamp, because the semiconductor LED high-power illumination is when power reaches a certain amount of, heat dissipation problem is difficult to solve, existing LED street lamp, the most radiator that adopts of its heat abstractor dispels the heat, and its structure is as shown in Figure 1, the street lamp of said structure, the fin of its heat-dissipating casing is provided with up, and its circuit board is arranged on the drain pan, and the drain pan top is provided with fin again.
The street lamp radiation fins of said structure there is bigger shortcoming:
1, the environment owing to street lamp of said structure is open-air work down, be in for a long time under dust rainwater and the salt fog illumination, because fin is provided with up, the radiator surface easily forms dirt deposition, thereby thereby causes the heat dissipation decay to have influence on the service behaviour and the life-span of street lamp.
2, in addition, because circuit board is arranged on the drain pan, the drain pan top is provided with fin again, has the contact temperature difference, poor thermal conductivity, and radiating effect is bad.
Summary of the invention:
The utility model purpose is to overcome above-mentioned shortcoming, and a kind of road LED illuminating street lamp heat-dissipating casing is provided, and it is simple in structure, the interior formation dirt deposition that is difficult for of fin groove, can effectively guarantee radiating effect.
For reaching above-mentioned purpose, the utility model adopts following technical scheme:
Road LED illuminating street lamp heat-dissipating casing comprises body and fin, and described fin is arranged on the body below down.
Described body upper surface arc.
Described body and fin are one-body molded.
Described body and lamp stand are directly affixed.
Adopt technique scheme, its advantage is:
1, because its fin is provided with, can effectively prevent dirt deposition down, guarantee radiating effect, improve the service behaviour and the service life of street lamp.
2, because the body upper surface forms arc, rainwater, dust can in time flow down along arcwall face, also can effectively prevent dirt deposition.
3, because body and fin are one-body molded, its integral heat sink area is big, and better heat-radiation effect.
4, its overall fixed, intensity height, wind resistance pressure, sound construction.
5, because body and lamp stand are directly affixed, Wind-Pressure Resistance, and directly contact lamp stand and heat can be increased the heat radiation of efficiently radiates heat conductor by lamp stand heat conduction, the raising security performance.
Description of drawings:
Below with accompanying drawing the utility model is described in detail:
Fig. 1 is the utility model prior art constructions schematic diagram;
Fig. 2 is a structural representation one of the present utility model;
Fig. 3 is a structural representation two of the present utility model.
The specific embodiment:
Below in conjunction with drawings and Examples the utility model is described in detail:
As Fig. 2, embodiment of the present utility model shown in Figure 3, road LED illuminating street lamp heat-dissipating casing, comprise body 1 and fin 2, described fin is arranged on the body below down, described body upper surface arc 11, described body and fin are one-body molded, and described body 1 is directly affixed with lamp stand.
Adopt technique scheme, because its fin is provided with, and can effectively prevent dirt deposition, guarantee radiating effect down, improve the service behaviour and the service life of street lamp, in addition, the body upper surface forms arc, and rainwater, dust can in time flow down along arcwall face, also can effectively prevent dirt deposition, because body and fin are one-body molded, its integral heat sink area is big, and better heat-radiation effect; Its overall fixed, intensity height, wind resistance pressure, sound construction; Because body and lamp stand are directly affixed, Wind-Pressure Resistance, and directly contact lamp stand and heat can be increased the heat radiation of efficiently radiates heat conductor by lamp stand heat conduction, the raising security performance.
