Description
[technical field]
The utility model relates to technical field of semiconductor illumination, especially a kind of energy-saving LED road lamp of heat sinking structure.
[background technology]
The LED lighting engineering has characteristics such as energy-saving and environmental protection, the life-span is long, volume is little as light source technology of new generation, can be widely used in fields such as various indications, demonstration, decoration, backlight, common, industrial lighting and urban landscape.
Led light source adopts and carries the combination of constant-current driven module formula, DC driven.Have super low-power consumption, compare energy-conservation more than 50% with conventional light source.In the service life of LED, it is generally acknowledged has 100,000 hours under perfect condition.Reality in use, its light intensity can decay (being light decay) in time gradually, promptly led light source will reduce the efficient that electric energy is converted into luminous energy gradually.In led light source was used, particularly in high-power, high-brightness LED light source applications, the light decay of led light source and its node operating temperature were contacted directly.When the node operating temperature is higher than 70 ℃, the working life of light source will significantly descend, and experimental results show that: when surpassing 70 ℃, LED does 5 ℃ of the every risings of temperature, and the LED light decay increases by 10%, under the normal condition, LED makes temperature and should be controlled at below 60 ℃, could guarantee the service life more than 100,000 hours.Therefore, how to dispel the heat and just become the key that guarantees the led light source reliably working life-span, but, in the practical application, for the angle of appreciation attractive in appearance, it is too big that light fixture often can not be done, so led light source and drive circuit chip thereof often are arranged in the limited scope in space, be the operating temperature that reduces node by the mode of natural heat dissipation fully, thereby poor effect.
Street lamp is in outdoor environment for a long time, requires waterproof and dustproof, protection against insect on the structure, and its lampshade must be the cavity of a sealing.The LED of LED street lamp will work in the environment of sealing equally, and this just means that it can't can only outwards dispel the heat by lampshade by cross-ventilation directly to external world's heat radiation.For this reason, some technical staff is provided with fin at substrate back, and the heat that LED is sent in time is dispersed in the air by fin.But the radiating efficiency of the fin of prior art is low.
[summary of the invention]
The purpose of this utility model is to provide a kind of simple in structure, good heat dissipation effect, water resistance is good, maintenance cost is few LED street lamp.
To achieve these goals, the technical solution of the utility model is the energy-saving LED road lamp of a kind of heat sinking structure of structure, comprise lamp holder, some LED lamps are installed on the lamp holder, base surface comprises a radiator, it is characterized in that: described radiator is provided with semiellipse spheroid radiating surface, and the both sides of described radiating surface are provided with some flow-like radiating ribs.
Wherein, preferred version is: the distance between the described radiating ribs does not wait, and the spacing of nearly oval ball is greater than center distance.
Wherein, preferred version is: the center of described radiating surface comprises plurality of strengthening ribs, because this reinforcement is arranged at the major radius place of semiellipse spheroid radiating surface, thereby when increasing the intensity of this housing, also can prevent rainwater, dirty dirt precipitation.
Wherein, preferred version is: be provided with some waterproof breach in the middle of the described flow-like radiating ribs, described waterproof breach can prevent rainwater, dirty dirt precipitation.
Wherein, preferred version is: the class of a curve of described flow-like radiating ribs is similar to the flow curve of thermal current.
Wherein, preferred version is: described flow-like radiating ribs can be strip.
Advantage of the present utility model is: good heat dissipation effect, durability height, and long service life, original basis is provided with waterproof breach and reinforcement simultaneously, has improved the water-proof function of product, has further prolonged the service life of product.

Fig. 2 is the structure principle chart of radiator of the energy-saving LED road lamp of a kind of heat sinking structure of the utility model.
[specific embodiment]
Radiator structure and effect for better explanation the utility model LED street lamp further specify it below in conjunction with accompanying drawing.
As shown in Figure 1: embodiment of the present utility model: a kind of energy-saving LED road lamp of good heat dissipation effect, comprise lamp holder, some LED lamps are installed on the lamp holder, base surface comprises a radiator 3, described radiator 3 is provided with semiellipse spheroid radiating surface 31, and the both sides of described radiating surface 31 are provided with some flow-like radiating ribs 32.The center of described radiating surface 31 comprises plurality of strengthening ribs 33, because this reinforcement 33 is arranged at the major radius place of semiellipse spheroid radiating surface 31, that is to say when thereby the height that is arranged at semiellipse spheroid radiating surface 31 increases the intensity of this radiator 3, also can prevent rainwater, dirty dirt precipitation.
The circular-arc arrangement in both sides that described flow-like radiating ribs 32 is low along high both sides in the center line 34, wherein, the curve design of described radiating ribs 32 meets the flow curve of thermal current, distance between the described radiating ribs does not wait, the spacing of nearly oval ball is greater than center distance, thereby improves its radiating effect more greatly.
The centre of described radiating ribs 32 can be provided with some waterproof breach 321, is similar to, and radiating ribs 32 part cloth are continuous, is disconnected by waterproof breach 321, and described like this waterproof breach 321 guiding rainwater drip from this breach 321, thereby prevent rainwater, dirty dirt precipitation.
Described flow-like radiating ribs 32 also can be strip.
Advantage of the present utility model is: good heat dissipation effect, durability height, and long service life, original basis is provided with waterproof breach and reinforcement simultaneously, has improved the water-proof function of product, has further prolonged the service life of product.
The above person is the utility model most preferred embodiment only, is not to be used to limit scope of the present utility model, and all equivalences of being done according to the utility model claim change or modify, and are all the utility model and contain.
