Abstract
A high-power LED street lamp comprises a lamp main body, wherein the light source mounting surface of the lamp main body is provided with an area for accommodating a lens; the lens is sealed and fastened in the area through a lens gland and a fastening piece; and a seal ring is arranged between the lens gland and the light source mounting surface. The high-power LED street lamp is characterized in that the light source mounting surface and the area are on the same plane surface; the bottom plane surface of the seal ring is directly adhered to the light source mounting surface; and a surface radiating fin is arranged at the periphery of the light source mounting surface. As the light source mounting surface and the area for accommodating the lens are designed on the same plane surface, and no seal ring caulking groove is formed on the light source mounting surface in the area for accommodating the lens, the structure of the lamp main body becomes relatively simple, the manufacture is convenient, and the cost is low; and as the surface radiating fin is arranged on the surface of the light source mounting surface, and the surface radiating fin and the light source mounting surface as well as a back radiating fin and the light source mounting surface form an integral body, the radiating area is greatly increased, and the effect is obvious.
Description
[technical field]
The utility model belongs to a kind of high-power LED street lamp.
[background technology]
At present, high-power LED street lamp is subjected to people's favor day by day with advantages such as its energy-saving and environmental protection, is described as the green illumination product of 21 century, and still, also there are problems in existing high-power LED street lamp, has hindered its fast development.Wherein, production cost height, radiating effect are poor, are the bottleneck problems of LED development always.LED is a kind of photoelectric component, have only 15%～25% electric energy to convert luminous energy in the course of the work, all the other all convert heat energy to, will cause accumulation of heat if can not in time derive heat, cause junction temperature to rise rapidly, and junction temperature is high more, the light decay of LED is just big more, service life is just short more, when junction temperature surpasses maximum allowable temperature (being generally 150 ℃), great power LED can be because of crossing cause thermal damage, therefore, in the high-power LED street lamp design, radiating effect will directly influence the decay of the aging and LED of electronic devices and components.
[summary of the invention]
For overcoming the problems referred to above that prior art exists, the utility model aims to provide a kind of high-power LED street lamp, and this street lamp has that production cost is low, the advantage of good heat dissipation effect compared with similar products.
For achieving the above object, the utility model has adopted following technical scheme: the structure of this high-power LED street lamp, comprise a lamp main body, the zone that has admittance lens on the light source installed surface of described lamp main body, lens are fastened in the described zone through the securing member sealing by the lens gland, be provided with sealing ring between lens gland and the described light source installed surface, it is characterized in that: described light source installed surface and described location are on same plane, and the baseplane of sealing ring directly posts on described light source installed surface.
During concrete enforcement, the periphery of described light source installed surface is provided with the face fin.
During concrete enforcement, described fin is arranged on the left and right sides of described light source installed surface.
Beneficial effect: compared with prior art, the utility model becomes a plane with the light source installed surface with the zone design of admitting lens, and in the zone of light source installed surface admittance lens the sealing ring caulking groove is not set, therefore, make the structure of lamp main body become simple relatively, cost easy to process is low.Moreover, on the surface of light source installed surface the face fin is set, owing to face fin, back of the body fin all constitute integral body with the light source installed surface, therefore, increased area of dissipation greatly, effect is obvious.
Also in conjunction with the accompanying drawings the utility model is further described below by embodiment.
[description of drawings]
Accompanying drawing is the parts decomposition texture schematic diagram of an embodiment of the utility model.
Among the figure: lamp main body 1, light source installed surface 11, face fin 12, back of the body fin 13, sealing ring 2, lens 3, lens gland 4, fixing threaded hole 41.
[specific embodiment]
Referring to accompanying drawing.The structure of this high-power LED street lamp comprises lamp main body 1, sealing ring 2, lens 3, lens gland 4.The zone that has admittance lens on the light source installed surface 11 of described lamp main body 1, lens 3 are fastened on the described zone by fixing threaded hole 41 sealings through securing member by lens gland 4.This zone generally is positioned at the middle part of light source installed surface 11.Sealing ring 2 is arranged between lens gland 4 and the described light source installed surface 11.
The utility model compared with prior art mainly contains two innovative points: at first, and the installing structure difference of sealing ring 2.Prior art is that a caulking groove of admitting sealing ring 2 is set in the zone of light source installed surface 11 admittance lens 3, is pressed on the sealing ring 2 by lens gland 4 again, realizes sealing, will increase manufacturing procedure and caulking groove is set, and improves production cost.The utility model then will admit the zone of lens 3 and light source installed surface 11 to be designed to same plane, rely on lens gland 4 directly to carry out the sealing and fixing of sealing ring 2, therefore, omitted manufacturing procedure one, help reducing production costs, also can improve the product firmness simultaneously.Secondly, face fin 12 (being commonly called as radiating fin) is set on light source installed surface 11, owing to face fin 12, back of the body fin 13 all are connected into integral body with light source installed surface 11, therefore, radiating effect obviously increases.
The shape of face fin 12, position etc. is set decides, for example: the left and right sides that is arranged on described light source installed surface 11 by feelings.
