Abstract
The utility model relates to a light-emitting diode (LED) street lamp. The LED street lamp comprises a radiator, an upper shell, an illuminating module, a side cover and an optical panel, wherein the upper shell is connected with the radiator; the illuminating module is arranged on the radiator; the side cover surrounds the illuminating module and is connected with the radiator; the optical panel is connected with the side cover; and a light source cavity is formed among the illuminating module, the side cover and the optical panel. The LED street lamp is characterized in that: the illuminating module comprises an LED light source which is arranged on the radiator and an asymmetrical light distribution lens which is arranged at the periphery of the LED light source. After the asymmetrical light distribution lens is adopted, light rays emitted from the LED light source pass through the asymmetrical light distribution lens and are refracted and distributed by the lens, so that more light rays are radiated to the road surface which is far away from a lamp, illumination loss caused by distances is made up and the uniformity of the entire road surface is higher. The asymmetrical light distribution lens is used, so that the irradiation region of the entire lamp is easier to control and the lamp brings a forward sense.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of LED street lamp, side cover that comprises radiator, is connected the loam cake that is provided with described radiator, is arranged on illumination module on the described radiator, is connected with described radiator around described illumination module and the optic panel that is connected setting with described side cover; Described illumination module, described side cover, and described optic panel between constitute light-source chamber; It is characterized in that: described illumination module comprises the lens that are arranged on the led light source on the described radiator and are arranged on described led light source periphery; Described lens are asymmetric light-distribution lens.
A kind of LED street lamp of the present invention, preferred, drive end bearing bracket and left cap that is oppositely arranged and right cap that described side cover comprises rear end cap near lamp stand, is oppositely arranged with described rear end cap; Described side cover and described radiator and described optic panel seal by waterproof adhesive tape.
A kind of LED street lamp of the present invention, preferred, the line of symmetry of described lens does not overlap with the line of symmetry of described led light source; The center line of described lens is near described drive end bearing bracket; Described led light source is near described rear end cap.
A kind of LED street lamp of the present invention, preferred, described left cap and right cap are the aluminium section bar of high heat dispersion.
A kind of LED street lamp of the present invention, preferred, described LED street lamp also comprises lamp stand that fixes on the ground and the lamp stand holder that is connected setting with described loam cake.
The utility model can reach following beneficial effect: by adopting the light-distribution lens of asymmetry, the light that led light source sends is earlier by the asymmetry light-distribution lens, lens reflect light and distribute, make the more trends of purchasing of the light road surface far away apart from light fixture, thereby remedy because distance is former thereby illumination that cause is lost, the uniformity on whole road surface is more increased.The utility model uses asymmetric light-distribution lens, can realize more easily controlling the irradiation area of whole light fixture, makes light fixture that a kind of sense is forward arranged simultaneously.

The specific embodiment
Understand for technical characterictic of the present utility model, purpose and effect being had more clearly, now contrast accompanying drawing and describe the specific embodiment of the present utility model in detail.
As Fig. 1～4 is a preferred embodiment of the present utility model, a kind of LED street lamp, side cover that comprises radiator 1, is connected the loam cake 6 that is provided with radiator 1, is arranged on illumination module on the radiator 1, is connected with radiator 1 around illumination module and the optic panel 3 that is connected setting with side cover.Illumination module, side cover, and optic panel 3 between constitute light-source chamber.
Illumination module comprises aluminium base 11, led light source 10 that is arranged on the radiator 1 and the lens 9 that are arranged on led light source 10 peripheries.Lens 9 are asymmetric light-distribution lens, are fixed on the aluminium base 11 by UV glue.The line of symmetry of lens 9 does not overlap with the line of symmetry of led light source 10; The center line of lens 9 is near drive end bearing bracket 8; Led light source is near rear end cap.The light that led light source sends is earlier by the asymmetry light-distribution lens, lens reflect light and distribute, make the more trends of purchasing of the light road surface far away, thereby remedy, the uniformity on whole road surface is more increased because distance is former thereby illumination that cause is lost apart from light fixture.
The LED street lamp also comprises lamp stand that fixes on the ground and the lamp stand holder 5 that is connected setting with loam cake.Side cover comprises drive end bearing bracket 8 that is oppositely arranged near the rear end cap of lamp stand, with rear end cap and left cap 4 and the right cap that is oppositely arranged; Side cover and radiator 1 and optic panel 3 are realized sealing by waterproof adhesive tape.
