Abstract

The utility model discloses an LED (light-emitting diode) street lamp, comprising a light source assembly with an independent cavity; the light source assembly is arranged and fixed on a base assembly; the base assembly comprises a plurality of laminates which are arranged in parallel at certain intervals; a middle heat dissipation body is correspondingly arranged between every two laminates along the back of the light source assembly; heat dissipation body are arranged at the back of the laminate at final layer and corresponding to the middle heat dissipation bodies; as the light source assembly of the LED street lamp is separated with the heat dissipation bodies and has the separate cavity, the waterproof sealing of the light source component is easily realized; the base assembly is formed by a plurality of laminates which are arranged in parallel at certain intervals; therefore, the laminate design can form the laminar flow under the wind power action; the wind resistance is greatly reduced; simultaneously the wind energy is effectively used, and the heat dissipation performance of the LED light source assembly is improved.

Description

A kind of LED street lamp

Technical field

The utility model relates to a kind of street lamp, especially a kind of LED street lamp.

Background technology

The LED street lamp that existing market occurs normally is placed on all parts such as led light source assembly, radiator in the housing, and the structural design of housing is traditional case form, and there is the problem of several aspects in such structural design: 1, windage is big; Use as street lamp, height hangs on the spacious road bar, and the center of gravity height adds that upper volume is big, windage is big, and streaming property is poor, has higher potential safety hazard; 2, poor radiation; Light source assembly and radiator all are arranged in the case, only depend on housing to realize heat exchange in the external world, and radiating effect is bad, and light source assembly is worked under hot environment for a long time, easily cause light source decay, reduce lamp body service life; 3, be difficult for realizing waterproof sealing; Use out of doors for a long time, cause light source fails for preventing rain penetration, the excellent waterproof sealing must be arranged, traditional LED lamp post structure is difficult for realizing.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provides that a kind of windage is little, thermal diffusivity good, and light source is easily realized the LED street lamp that seals.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of LED street lamp, it is characterized in that: the light source assembly that comprises individual cavity, described light source assembly is fixed on the base assembly, described base assembly comprises a plurality of laminates that keep at a certain distance away and be arranged in parallel, along light source assembly rear portion correspondence middle radiator is installed between described per two laminates.

As further improvement in the technical proposal, the end in the described a plurality of laminates middle radiator of postlaminar part correspondence place layer by layer is equipped with the afterbody radiator; Described centre, afterbody radiator are splintery heronsbill radiator, and there is louvre at the radiator center, behind the afterbody radiator waterproof cover are installed; Described a plurality of laminate is three layers, and there is black oxide layer on the mesosphere board surface.

The fixing body that can be connected with light pole is equipped with at described end postlaminar part layer by layer, and described fixing body comprises and be fixed on the end mount pad and the installing handle that is connected with light pole of postlaminar part layer by layer, and match with the installing handle end face of installation of described mount pad is the profile of tooth end face.

As preferred implementation of the present utility model, described light source assembly comprises lampshade, lamp housing, lamp housing inside is provided with the led light source group, described led light source group is fixed on the hot substrate, described hot substrate is fixed on the diversion seat, described diversion seat center is provided with louvre, and this louvre is divergent shape to periphery and is distributed with a plurality of diversion grooves certainly.

The beneficial effects of the utility model are: because light source assembly of the present utility model separates with radiator, independently cavity is arranged, realize the waterproof sealing of light source assembly easily; Base assembly is a plurality of laminates that keep at a certain distance away and be arranged in parallel, and such laminate design can form laminar flow under the wind-force effect, not only reduce windage greatly, effectively utilizes wind energy simultaneously, improves the heat dispersion of led light source assembly; When light source assembly adopted the structure of the utility model optimal way, surrounding air flowed to the center louvre through the diversion groove of diversion seat, thereby takes away the heating heat of led light source group, has improved the radiating efficiency of lamp body greatly.

Description of drawings

Following accompanying drawing further specifies the utility model.

Fig. 2 is Fig. 1 broken away view;

Fig. 3 is the broken away view of light source assembly;

Fig. 4 is the structural representation at the utility model rear portion.

The specific embodiment

With reference to Fig. 1, Fig. 2, a kind of LED street lamp, the light source assembly 1 that comprises individual cavity, described light source assembly 1 is fixed on the base assembly 2, described base assembly 2 comprises a plurality of laminates 21 that keep at a certain distance away and be arranged in parallel, along light source assembly 1 rear portion correspondence middle radiator 22 is installed between described per two laminates.End in the described a plurality of laminate 21 middle radiator of plate 211 rear portion correspondences 22 places layer by layer is equipped with afterbody radiator 23.Described centre, afterbody

radiator

22,23 are splintery heronsbill radiator, and there is louvre 4 at the radiator center, and waterproof cover 5 is installed behind the afterbody radiator 23.Described can be set to as required two-layer, three layers or more, when laminate is three layers or when above, there is black oxide layer on the surface of its mesosphere board 212.

Because light source assembly of the present utility model separates with radiator, independently cavity is arranged, only need the cavity at light source assembly place to be connected to seal to get final product by screw and marine glue, realize the waterproof sealing of light source assembly easily; Base assembly is a plurality of laminates that keep at a certain distance away and be arranged in parallel, and such laminate design can form laminar flow under the wind-force effect, not only reduce windage greatly, effectively utilizes wind energy simultaneously, improves the heat dispersion of led light source assembly.Between per two laminates and end is radiator and afterbody radiator in the middle of correspondence is equipped with on the plate layer by layer, the heat of led light source assembly can be conducted out by radiator as early as possible.When there is black oxide layer on plate surface, intermediate layer, can absorb interior heat on heronsbill radiator and the laminate and transform then and discharge, radiating effect is better.
