Abstract
The invention discloses an LED (Light-Emitting Diode) street lamp radiator with a stirrer, which comprises a radiator in which a first closed cavity is arranged; a radiating solution is disposed in the first cavity; the surface wall of the radiator extends outwards to form multiple bumps; second cavities communicating with the first cavity are arranged in the bumps; gaps are reserved among the bumps; the stirrer is installed in the first cavity. Through the LED street lamp radiator, the efficiency of radiating the heat generated by the lamp outwards can be quickened; further, the LED street lamp radiator is simple in structure and low in cost; and the service life, stability and using effect of the LED street lamp are effectively improved.
Description
Technical field
The present invention relates to a kind of LED street lamp heat radiator of belt stirrer.
Background technology
The LED street lamp is semi-conductor lighting lamp.It is the high efficiency solid-state light source that the faint electric energy of usefulness that a kind of based semiconductor PN junction forms just can be luminous, under certain forward bias voltage and Injection Current, the electronics that injects the hole in P district and injection N district sends photon diffusing to active area by radiation recombination, electric energy is converted into luminous energy.It is a kind of solid state light emitter.The characteristics such as have environment friendly and pollution-free, little power consumption, light efficiency is high, the life-span is long, therefore, the LED street lamp will become the optimal selection that roadway illumination and energy saving is transformed.But, the LED street lamp is in luminous, also can produce a large amount of heat, if can not timely and effectively dispel the heat, be deposited in led light source heat on every side and will cause light source to be decayed fast, energy consumption increases, thereby affects life-span and the stability of LED lamp, but the LED street lamp heat radiator effect of existing belt stirrer is bad, and cost is high.
Summary of the invention
Problem for the prior art existence, the object of the invention is to propose a kind of LED street lamp heat radiator of belt stirrer, can accelerate the efficient of outwards being distributed by the heat that the LED street lamp produces, simple in structure, with low cost, service life, stability and result of use that can Effective Raise LED street lamp.
For reaching this purpose, the present invention by the following technical solutions:
A kind of LED street lamp heat radiator of belt stirrer, establish the radiator of the first airtight cavity in comprising, splendid attire heat radiation solution in described the first cavity, described heat radiation body surface wall extends outward some projections, establish the second cavity that is communicated with described the first cavity in the described projection, leave the gap between the described projection, the built-in agitator of described the first cavity.
Described radiator comprises several outerplanars, wherein only has the described projection that do not distribute on the outerplanar.
The described projection that is on the same described outerplanar is parallel to each other.
The described projection that is on the same described outerplanar evenly distributes on described outerplanar.
Based on disclosing of above technical scheme, the present invention possesses following beneficial effect:
The present invention can accelerate the efficient of outwards being distributed by the heat that the LED street lamp produces, and is simple in structure, with low cost, service life, stability and result of use that can Effective Raise LED street lamp.
Description of drawings
Fig. 1 is the overall structure schematic diagram of the embodiment of the invention 1.
The specific embodiment
Further specify technical scheme of the present invention below in conjunction with accompanying drawing and by the specific embodiment:
A kind of LED street lamp heat radiator of belt stirrer is proposed, be used for the heat radiation of LED street lamp, establish the radiator of the first airtight cavity 4 in comprising, the first cavity 4 interior Sheng heat radiation solution, radiator comprises several outerplanars 2, remove outside that outerplanar 2 that the LED module is installed, the table wall of every other outerplanar 2 all extends outward some protruding 1, be between the projection 1 on the same outerplanar 2 and be parallel to each other, and evenly distribute, leaving gap 12 between the projection 1, the first cavity 4 is offered in the inside of projection 1, the first cavity 4 is communicated with the second cavity 11, so that heat radiation solution can flow to the second cavity 11 through the first cavity 4, agitator 3 is installed in the first cavity 4, the LED street lamp in use, the heat process of distributing does not have the conduction of an outerplanar 2 of projection 1, enter heat radiation solution, because the heat radiation solution temperature is lower, the heat conduction is very fast, agitator 3 work, make the spread heat that enters heat radiation solution, owing to having gap 12 between the projection 1, this gap 12 becomes heat radiation solution to the passage of extraneous heat release, the heat release area that is made of the gap 12 of projection between 1 is far longer than the surface area of outerplanar 2, the efficient of the outside heat release of heat radiation solution is improved greatly, thereby the heat that is produced by the LED street lamp is distributed faster.The present invention is simple in structure, and is with low cost, service life, stability and result of use that can Effective Raise LED street lamp.
The above; only be the better specific embodiment of the present invention; but protection scope of the present invention is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to replacement or change according to technical scheme of the present invention and inventive concept thereof, all should be encompassed within protection scope of the present invention.
