A kind of LED street lamp

Technical field:

The utility model relates to street lamp, and is especially simple in structure, volume is little, good heat dissipation effect, the rational a kind of LED street lamp of illumination patterns.

Background technology:

High-power LED street lamp relates generally to heat radiation in design at present, light this two problems that distribute: 1. on the heat dissipation problem, because the substrate of LED diode produces a large amount of heat accumulations in the seal cavity of lamp housing during great power LED work, can influence the service behaviour and the life-span of LED light emitting diode, therefore must carry out quick heat radiating to it, traditional practice is that fin is installed on lamp housing at present, to reach the enclosure interior heat is carried out hot delivery type heat radiation by the area of dissipation that increases housing, this radiating mode is non-directly to carry out heat transmission heat radiation to high power LED substrate, therefore radiating effect is not good, influences service behaviour and the service life of LED; 2. on the light distribution problem, present LED street lamp needs to control illumination and penetrates wide-angle to reach the illumination patterns requirement of needs on structural design, but because the luminous characteristics of LED, the mode that must adopt secondary optics to handle is carried out the optically focused refraction, at present mainly by adopting secondary optical lens to realize, this has not only increased the cost of LED street lamp, also increased the volume of whole lamp, influence the aesthetic feeling of street lamp outward appearance greatly, and also can't solving illumination, to penetrate wide-angle big, shine far away and little this contradiction of luminous intensity, therefore the light of the LED street lamp of this structure in the application of road surface distributes and remains uneven.Illumination wide-angle and the light intensity of controlling each monomer LED by the mode that puts rectangular light cup optically focused on the LED of each monomer diode also arranged at present, and some rectangular light cup LED diodes that are arranged with are arranged light emitting source as the LED street lamp as the monomer light source, but adopt this mode and structure can't realize that still the illuminance of LED street lamp rationally distributes.

The utility model content:

For solving existing problem on the above-mentioned high-power LED street lamp structural design, this is novel be intended to propose a kind of simple in structure, volume is little, good heat dissipation effect, the rational LED street lamp of light distribution.

The technical scheme in the invention for solving the above technical problem is: a kind of LED street lamp, contain lamp socket, circuit board and LED light emitting module that luminous chamber is an inverted ladder type, it is characterized in that: the middle, luminous chamber of lamp socket is provided with the ladder type platform, inclined-plane, ladder type platform both sides and inboard wall of lamp holder form the V-type groove, and the LED light emitting module is installed in respectively on the top table top and inclined-plane, both sides thereof of ladder type platform; Circuit board is installed in the power supply containing cavity of lamp socket, and circuit board is electrically connected with the LED light emitting module by lead; Lamp socket is provided with and its edge fit lampshade mutually, offers the light inlet window corresponding with luminous chamber on the lampshade, and light inlet window and luminous top of chamber are provided with dull and stereotyped transparent toughened glass.

Ladder type platform of the present utility model and lamp socket are one-body molded, and ladder type platform top is carved with down terraced groove, and the LED light emitting module is installed and fallen in the terraced groove; The LED light emitting module is that square is tabular, and it is for being provided with the great power LED light emitting diode of some series, parallel or series-parallel connection on aluminium base, and aluminium base directly forms good heat with the ladder type platform and conducts and be connected and fixed; Front end at lamp socket and lampshade is connected by the butterfly sheet; Lamp socket and lampshade rear end are respectively equipped with and integrated half clasp of they difference, and half clasp on the lamp socket is provided with spring secures rail to sleeper, and the decometer of buckleing that half clasp on spring secures rail to sleeper and the lampshade is provided with is buckled; The lamp socket back side is provided with radiating ribs integrated with it, be used for the heat that is produced of great power LED diode by lamp socket itself and on radiating ribs fast conduction scatter and disappear away.

The beneficial effects of the utility model are: by ladder type platform in the middle of being provided with in the luminous chamber of lamp socket, and at the top of ladder type platform table top and inclined-plane, both sides installation LED light emitting module thereof, light is reflected from the V-type groove face of ejaculation of top table top and both sides, reach standard bat shape light distribution effect, solved illumination penetrate wide-angle big, when irradiation is far away and this contradiction of illuminance irrational distribution; The LED substrate of LED light emitting module simultaneously is connected with aluminium base, the heat that aluminium base is assembled can be connected and fixed by the good conduction of itself and lamp socket and pass to lamp socket, by the lamp socket body and on the radiating ribs quick heat radiating, make the stable work in work of great power LED, improve service life of the present utility model.
