Abstract
The utility model discloses an LED street lamp which belongs to the technical field of lamps. The LED street lamp comprises a lamp body, wherein the lamp body is a flat shell, the front part of the lamp body is provided with a light-transmission hood, a front waterproof rubber ring is arranged between the light-transmission hood and the lamp body, at least one LED light source mould is fixedly arranged on the rear part of the lamp body through a bolt or a becket, and the LED light source mould is composed of an aluminum alloy substrate, a plurality of LED lamps fixed on the inner lateral surface of the aluminum alloy substrate, and a metal heat radiation plate fixed on the outer surface of the aluminum alloy substrate. The utility model has the advantages of simple structure, better heat radiation effect, fast maintenance and low cost and is used for illumination on streets.
Description
Technical field
The utility model relates to a kind of light fixture, and more particularly, it relates to a kind of LED street lamp.
Background technology
Utilize high-capacity LED lamp as street lighting, have that energy consumption is low, the advantage of long service life, thereby obtained using widely.At present, traditional LED street lamp is that LED lamp body and heat sink are all sealed assembling in the enclosure, and this structure exists radiating effect relatively poor, influences the deficiency in the service life of LED lamp body; And break down when needing repairing at street lamp, lamp body all need be pulled down, there is the constant deficiency of maintenance.
The utility model content
The technical problems to be solved in the utility model is the above-mentioned deficiency at prior art, and a kind of simple in structure, LED street lamp that radiating effect is better, easy to maintenance is provided.
The technical solution of the utility model is such: a kind of LED street lamp, comprise lamp body, wherein, described lamp body is the pancake housing, in the lamp body front portion diffuser is installed, between diffuser and lamp body, is provided with preceding waterproof apron, be installed with at least one led light source module by screw or latch closure at the lamp body rear portion, described led light source module is by aluminium alloy base plate, and a plurality of LED lamps that are fixed on the aluminium alloy base plate medial surface are formed with the metallic heat radiating plate that is fixed on the aluminium alloy base plate lateral surface.
In above-mentioned a kind of LED street lamp, be provided with the back waterproof apron between described aluminium alloy base plate and the lamp body, with water resistance that strengthens lamp body and the water proof and dust proof grade that reaches necessity.
In above-mentioned a kind of LED street lamp, described aluminium alloy base plate and heat sink are overall structure, can directly reduce manufacturing procedure like this, reduce production costs.
In above-mentioned a kind of LED street lamp, be provided with metallic reflector or even optical lens between described led light source module and the diffuser, can make distribution of light even like this, improve the road lighting effect.
After the utility model adopted said structure, by directly heat sink being arranged on outside the lamp body, the radiating effect of lamp body was very good, can guarantee the operate as normal of LED lamp; And by screw or latch closure fixed installation led light source module, the dismounting of light fixture and maintenance are also very convenient, do not need when light fixture breaks down light fixture is all pulled down, only need be by the light fixture top
The led light source Mo Group of fault changes renewal and gets final product.
Description of drawings
Below in conjunction with the embodiment in the accompanying drawing the utility model is described in further detail, but does not constitute any restriction of the present utility model.
Fig. 1 is the perspective view of a kind of specific embodiment of the utility model;
Fig. 2 is a structural representation of the present utility model;
Fig. 3 is the utility model transversary schematic diagram;
Fig. 4 is to use view.
Among the figure: lamp body 1, light-passing board 2, preceding waterproof apron 3, aluminium alloy base plate 4, LED lamp 5, heat sink 6, back waterproof apron 7, even optical lens 8.
The specific embodiment
Consult Fig. 1 to shown in Figure 3, a kind of LED street lamp of the present utility model comprises lamp body 1, and lamp body 1 is the pancake metal shell, in lamp body 1 front portion diffuser 2 is installed, and diffuser 2 adopts armorplate glass; Waterproof apron 3 before being provided with between diffuser 2 and lamp body 1 is dustproof with the water-tight that guarantees lower surface; By screw one group of led light source module (also can adopt latch closure commonly used in the prior art to be connected and fixed) is installed at lamp body 1 rear portion, this led light source module is by aluminium alloy base plate 4, the a plurality of LED lamps 5 that are fixed on the medial surface of aluminium alloy base plate 4 are formed with the metallic heat radiating plate 6 that is fixed on aluminium alloy base plate 4 lateral surfaces, a plurality of LED lamps 5 wherein can adopt and be arranged in parallel or oval shaped arrangements, thereby form directional light or ellipse-shaped light; The effect of metallic heat radiating plate 6 be in time with LED lamp 5 when work the heat that produces distribute as soon as possible, in order to avoid temperature too high operate as normal and service life that influences LED lamp 5; Between aluminium alloy base plate 4 and lamp body 1, be provided with back waterproof apron 7, to strengthen the water proof and dust proof effect of lamp body; Between led light source module and diffuser 2, be provided with even optical lens 8 (metallic reflector can certainly be installed), even optical lens 8 is positioned at LED lamp 5 outsides, can spare light to the light that LED lamp 5 sends and handle, the distribution of light that LED lamp 5 is sent is even, improves the illuminating effect of road pavement; Even optical lens 8 is, can certainly be fixed in the lamp body 1 by support is set directly fixedly on the aluminium alloy base plate 4 by screw.
Aluminium alloy base plate 4 in the utility model can adopt overall structure with heat sink 5, can directly reduce manufacturing procedure like this, reduces production costs.
When the utility model specifically uses, consult shown in Figure 4ly, can be used as the general lighting lamp in roadside, can or utilize the solar panel power supply by common mains-supplied.
