Description
Technical field
The utility model relates to light fixture, relates in particular to a kind of high-power LED street lamp.
Background technology
Street lamp is the important component part of city illumination, and traditional street lamp often adopts high-pressure mercury lamp, and high-pressure mercury lamp 360 degree are luminous, and the shortcoming that light loss is large has caused the huge waste of the energy.Current, global environment is going from bad to worse, and each state is all at the development clean energy resource.And along with the rapid growth of national economy, China's energy supply and demand contradiction is outstanding day by day, the coming into existence situation of critical shortage of supply of electric power, and energy-conservation is present institute urgent problem.Therefore, development of new is efficient, energy-conservation, the life-span is long, colour rendering index is high, the LED street lamp of environmental protection is of great significance the energy-conservation tool of city illumination.The LED street lamp is semi-conductor lighting lamp, be with light emitting diode as light source, because it is a kind of solid-state cold light source, thereby have the characteristics such as environment friendly and pollution-free, little power consumption, light efficiency is high, the life-span is long.Existing LED street lamp generally all adopts led module is combined with radiating module, and radiating module and lamp outer casing close contact are delivered on the lamp outer casing by the heat with LED, carry out heat exchange with extraneous air again, by thermal-radiating passive heat dissipating method.This method all is in the thermal source radiation whole light fixture so that lamp interior is assembled a large amount of hot-airs, and LED works long hours in hot environment, and radiating effect is undesirable, greatly affects the service life of LED.In the Chinese patent application publication number CN1277665A document, a kind of LED lamp heat sink conception is disclosed, its heat radiation is the heat that absorbs the pedestal that connects LED by the joint pin in the lamp body in this scheme, then still in lamp body, dispel the heat, because it is repeatedly indirectly to dispel the heat, and in the sealing lamp body, dispel the heat poor effect.And for example in the Chinese patent application publication number CN1603679A document, a kind of LED lamp heat sink conception is disclosed, its heat radiation is that the heat (mainly being the heat of LED basal part) of LED sees through wiring board and leads the heat radiation glue-line and is sent to heat sink in this scheme, still be indirect heat radiation, radiating effect is still not good.
Summary of the invention
Therefore, for above-mentioned problem, the utility model proposes the high-power LED street lamp of a kind of long service life, good heat dissipation effect.
For achieving the above object, the utility model has adopted following technical scheme: a kind of high-power LED street lamp, comprise light cover, foot of radiator and be located at the interior high power LED integrated module of foot of radiator, described light cover is connected with foot of radiator, described foot of radiator is provided with fixed head, described high power LED integrated module is in fixed head is fixedly arranged on foot of radiator, described foot of radiator is provided with groove, described high power LED integrated module next door or bottom are equipped with heat pipe, and the free end of this heat pipe is located on the groove of foot of radiator.
Further, described foot of radiator is semicircle finned radiator base.
Further, described heat pipe is heat-conducting copper pipe.
By adopting the aforementioned techniques scheme, the beneficial effects of the utility model are: by adding a heat pipe at high power LED integrated module and foot of radiator, can in time heat be passed on the foot of radiator by heat pipe, thereby quick heat radiating, so that whole high-power LED street lamp is difficult for assembling amount of heat, whole light fixture all is in the thermal source radiation, prolonged the service life of LED, improve its radiating effect, thereby the utlity model has very big dissemination.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the front view of the utility model embodiment.
The specific embodiment
Now with the specific embodiment the utility model is further specified by reference to the accompanying drawings.
Consult illustrated in figures 1 and 2, a kind of high-power LED street lamp of the present utility model, comprise light cover 1, foot of radiator 2 and be located at high power LED integrated module 3 in the foot of radiator 2, described light cover 1 is connected with foot of radiator 2, described foot of radiator 2 is provided with fixed head 4, described high power LED integrated module 3 is in fixed head 4 is fixedly arranged on foot of radiator 2, described foot of radiator 2 is provided with groove 21, described high power LED integrated module 3 bottoms are equipped with heat pipe 5, and the free end of this heat pipe 5 is located on the groove 21 of foot of radiator 2, described foot of radiator 2 is semicircle finned radiator bases, and described heat pipe 5 is heat-conducting copper pipe.
The next door that heat pipe also can be arranged on high power LED integrated module in the utility model links to each other in order in time heat is passed on the foot of radiator by heat pipe with high power LED integrated module, thus quick heat radiating.
The utility model is by adding a heat pipe at high power LED integrated module and foot of radiator, can in time heat be passed on the foot of radiator by heat pipe, thereby quick heat radiating, so that whole high-power LED street lamp is difficult for assembling amount of heat, whole light fixture all is in the thermal source radiation, prolong the service life of LED, improved its radiating effect, thereby the utlity model has very big dissemination.
Although specifically show and introduced the utility model in conjunction with preferred embodiment; but the those skilled in the art should be understood that; within not breaking away from the spirit and scope of the present utility model that appended claims limits; can make a variety of changes the utility model in the form and details, be protection domain of the present utility model.
