Abstract
The utility model provides a ventilating structure of a lamp shell of an LED street lamp, belonging to the technical field of illumination equipment. The technical problems that the conventional lamp shells of LED street lamps have bad heat-radiating effect, relatively high manufacturing cost and the like are solved. The ventilating structure of the lamp shell of the LED street lamp comprises a lamp shell, and a plurality of heat-radiating grooves communicated with the interior of the lamp shell are arranged on the lamp shell. The ventilating structure of the lamp shell of the LED street lamp has the advantages of simple structure, good heat-radiating effect, low manufacturing cost and the like.
Description
Technical field
The utility model belongs to technical field of lighting fixtures, relates to a kind of aeration structure, particularly a kind of aeration structure of LED streetlamp housing.
Background technology
The LED street lamp is used in producing and living widely owing to its luminous efficiency height, long service life, free of contamination advantage.If untimely the distributing of the heat that the fluorescent tube of LED street lamp produces will be reduced the light efficiency of LED street lamp, reduce the life-span of LED street lamp simultaneously in luminescence process.
In order to solve above-mentioned technical problem, by retrieval, find that Chinese patent discloses a kind of LED lamp (patent No.: 99801548.2), it comprises a joint pin, crown top of burner that is connected with an end of joint pin and a pedestal that is connected with the other end of joint pin, and a plurality of LED are arranged on the pedestal, it is characterized in that this pedestal comprises the regular polyhedron of at least four faces, wherein polyhedral surface is provided with at least one LED, it has the luminous flux of 51m at least at the lamp duration of work, and wherein joint pin is provided with and pedestal and the interconnected heat abstractor of the crown top of burner.The LED lamp of this patent disclosure still dispels the heat in lamp body then by the heat of the pedestal of the absorption of the joint pin in lamp body connection LED, owing to be repeatedly to dispel the heat indirectly, and in the sealing lamp body, dispel the heat, so poor effect.
Chinese patent discloses a kind of super heat-conductive pipe lamp (patent No.: 01145733.3) for another example, it comprises a light-emitting device, a printing opacity cell-shell, driver and shell thereof, an arrangements of electric connection, it is characterized in that it also includes at least one super heat-conductive pipe, light-emitting device be positioned on the surface of heat absorbing end of super heat-conductive pipe or near, the radiating end of super heat-conductive pipe is connected with the heat abstractor close thermal.This patent is the heat that absorbs light-emitting device by super heat-conductive pipe one end, at the lamp body radiating piece of other end transfer of heat to the air contact, because it still takes indirect heat radiation, therefore radiating effect is not good, simultaneously, and this radiating mode, complex structure, the manufacturing cost height.
Summary of the invention
The purpose of this utility model is to have the problems referred to above at existing technology, has proposed the aeration structure of a kind of simple in structure, good heat dissipation effect, lower-cost LED streetlamp housing.
The purpose of this utility model can realize by following technical proposal: a kind of aeration structure of LED streetlamp housing, comprise lamp housing, and it is characterized in that, on lamp housing, offer the radiating groove that several communicate with lamp housing inside.
The aeration structure of this LED streetlamp housing is what to be used for to the heat radiation of the LED fluorescent tube of lamp housing inside and drive circuit, directly offers radiating groove on lamp housing, simple in structure, good heat dissipation effect, easily manufactured, cost is lower.
First kind of situation, in the aeration structure of above-mentioned LED streetlamp housing, described radiating groove is opened on the sidepiece of lamp housing.
Second kind of situation, in the aeration structure of above-mentioned LED streetlamp housing, described radiating groove is opened on the end of lamp housing.
The third situation, in the aeration structure of above-mentioned LED streetlamp housing, described radiating groove is opened on the end of the sidepiece of lamp housing and lamp housing simultaneously.
In the aeration structure of above-mentioned LED streetlamp housing, described radiating groove is strip.The radiating groove of strip is more conducive to heat dissipation ventilation.
In the aeration structure of above-mentioned LED streetlamp housing, the groove width of described radiating groove is 10mm～30mm.
Compared with prior art, the aeration structure of written or printed documents LED streetlamp housing is directly to offer radiating groove on lamp housing, simple in structure, good heat dissipation effect, easily manufactured, cost is lower.
