Abstract
The utility model provides an LED (light-emitting diode) streetlamp, comprising a lamp head and a lamp rod connected with the lamp head, wherein the lamp head comprises a lamp shell, LED light source modules and driving circuits; the lamp rod is provided with an overhaul port; the lamp shell comprises an upper shell and a lower shell which are formed in a split manner; the upper shell and the lower shell form two cavities together; the LED light source modules and the driving circuits are respectively distributed in the two cavities; and the upper surfaces and the lower surfaces of the cavities provided with the LED light source modules are respectively provided with radiating fins. In the LED streetlamp, the radiating performance of the LED light source modules can be effectively improved, and the service life and the color developing performance of an LED are greatly improved.
Description
Technical field
The utility model relates to a kind of street lamp, particularly a kind of LED street lamp.
Background technology
Traditional street lamp, power consumption is higher, causes that electricity consumption is very high, the feature of environmental protection is poor, and its luminosity is also not enough, makes that road lighting brightness is low, and is eliminated gradually.And the LED street lamp, owing to have the luminance height, the advantage that luminous intensity is big is popularized by large-and-medium size cities gradually.
At present, existing LED street lamp comprises lamp holder and coupled lamp stand, and wherein, lamp holder comprises lamp housing, light source module and drive circuit.Because LED is as street lamp, therefore general employing LED high-power, high brightness does light source.And the lamp housing one of present LED street lamp adopts traditional streetlamp housing to convert usually, drive circuit and light source module all are enclosed in the limited lamp housing space, and the natural way heat radiation is leaned in the heat radiation of LED street lamp substantially, and radiating effect is poor, has influenced service life and the colour rendering of LED greatly.
Summary of the invention
The purpose of this utility model is that the radiating effect that exists at above-mentioned prior art is poor, and causes the problem of short and colour rendering difference in service life of LED, and a kind of LED street lamp is provided.
The technical scheme taked of the utility model is to achieve these goals: a kind of LED street lamp comprises lamp holder and coupled lamp stand, wherein, lamp holder comprises lamp housing, led light source module and drive circuit, described lamp stand is provided with access hole, described lamp housing comprises upper shell and the lower house that branch is body formed, two chambers of the common formation of described upper shell and described lower house, described led light source module and described drive circuit are arranged in described two chambers, and the upper and lower surface that the chamber of described led light source module is housed is respectively equipped with radiating fin.
In order to increase the radiating effect of led light source module, the described lamp housing side that described upper shell and described lower house form is provided with corresponding window, and described window is used for heat loss through convection.
In order to increase the radiating effect of drive circuit, the chamber that described drive circuit is housed is provided with through hole, and described through hole is connected this chamber with the inside of described lamp stand, and described access hole is the venetian blind type access hole.
The beneficial effects of the utility model are: compared to existing technology, the utility model is located at led light source module and driver module in two chambers, and radiating fin is set in the upper and lower surface of the chamber that the led light source module is housed, effectively improve the heat dispersion of led light source module, improved service life and the color developing of LED greatly.
Description of drawings
Fig. 1 is the stereogram of LED street lamp described in the utility model;
Fig. 2 is that the A of the described lamp holder of Fig. 1 is to revolved view;
Fig. 3 is the view when lamp holder removes upper shell described in Fig. 2.
Among the figure: 1 upper shell, 2 lower houses, 3LED light source module, 4 radiating fins, 5 windows, 6 access holes, 7 lamp stands, 8 first chambers, 9 drive circuits, 10 second chambers, 11 through holes.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but not as to qualification of the present utility model.
As shown in Figure 1, a kind of LED street lamp described in the utility model, comprise lamp holder and coupled lamp stand 7, wherein, lamp holder comprises lamp housing, led light source module 3 and drive circuit 9, described lamp stand 7 is provided with access hole 6, described lamp housing comprises branch body formed upper shell 1 and lower house 2, described upper shell 1 and described lower house 2 be common to form two chambers (can referring to Fig. 3), i.e. first chamber 8 (can referring to Fig. 3) and second chamber 10 (can referring to Fig. 3), described led light source module 3 and described drive circuit 9 are arranged in described first chamber 8 (can referring to Fig. 3) and second chamber 10 (can referring to Fig. 3), be equipped with described led light source module 3 chamber on, lower surface is respectively equipped with radiating fin 4, promptly the lower surface of the upper surface of first chamber 8 (can referring to Fig. 3) and first chamber 8 (can referring to Fig. 1) is respectively equipped with radiating fin 4, effectively improve the heat dispersion of led light source module 3, improved service life and the color developing of LED greatly.
As shown in Figure 1, the described lamp housing side that described upper shell 1 and described lower house 2 form is provided with corresponding window 4, and described window 4 is used for heat loss through convection, has increased the radiating effect of led light source module 3.
As shown in Figure 2, the chamber that described drive circuit 9 is housed promptly is provided with through hole 11 in second chamber 10, described through hole 11 is connected the inside of this second chamber 10 and described lamp stand 7 (can referring to Fig. 1), described access hole 6 (can referring to Fig. 1) is a venetian blind type access hole 6, air can enter second chamber 10 by access hole 6 via through holes 11, cool off drive circuit 9, increased the radiating effect of drive circuit 9.
Above-described embodiment, the utility model specific embodiment a kind of more preferably just, the common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacing all should be included in the protection domain of the present utility model.
