Abstract
The invention discloses a radiating structure of a light emitting diode (LED) lamp and the LED lamp. The radiating structure of the LED lamp comprises at least one radiating body of which the surface is provided with a plurality of radiating fins, wherein the radiating body is provided with an air guide channel; and the surface of the radiating body is provided with at least one air hole communicated with the air guide channel. The LED lamp comprises at least one LED lamp bead and the radiating structure with the number corresponding to that of the LED lamp bead. Therefore, heat generated by the LED lamp bead in the working process can be radiated through the plurality of radiating fins on the surface of the radiating body, and also can be discharged through a radiating channel formed by the air guide channel and the air hole, the radiating structure can be more uniformly heated, and the radiating efficiency of the radiating structure is greatly improved.
Description
Technical field
The present invention relates to LED (Light Emitting Diode) technical field of lamps, more particularly, relate to a kind of LED lamp cooling structure and LED light fixture.
Background technology
Compare with incandescent lamp, the LED light fixture has following plurality of advantages: optical efficiency height, light quality height, energy consumption is little, the life-span is long, reliability and durability, applying flexible, safety, environmental protection, owing to have above advantage, it is inexorable trend that the LED light fixture replaces incandescent lamp, but to realize fully replacing incandescent lamp with the LED light fixture, so that the above-mentioned advantage of LED light fixture is brought into play, just must solve heat dissipation problem.
In the prior art, in order to strengthen radiating effect, designers' thinking normally increases the area of radiator structure, and the control of radiator structure internal heat air draught is then paid attention to inadequately.Can solve the derivation problem that LED lamp pearl produces heat to a great extent though increase the area of radiator structure, because the radiator structure internal gas flow is not smooth, the temperature of radiator can increase sharply, and the radiating effect of whole light fixture is still not good.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of LED lamp cooling structure, and it can form unimpeded heat dissipation channel.
Another technical problem to be solved by this invention is to provide a kind of light fixture with above-mentioned LED lamp cooling structure.
For LED lamp cooling structure of the present invention, above-mentioned technical problem is solved like this: provide a kind of LED lamp cooling structure to comprise that at least one surface has the radiator of a plurality of fin, described radiator has an air guide channel, and the surface of described radiator is provided with at least one pore that is communicated with described air guide channel.
For LED light fixture of the present invention, above-mentioned technical problem is solved like this: a kind of LED light fixture is provided, comprises at least one LED lamp pearl and quantity and the corresponding radiator structure of described LED lamp pearl, described radiator structure has above-mentioned structure.
Like this, the heat that LED lamp pearl produces in the course of the work both can be dispersed by a plurality of fin on radiator surface, also can flow out, make more thermally equivalent of radiator structure, and improve the radiating efficiency of radiator structure greatly via described air guide channel and the formed heat dissipation channel of pore.
Description of drawings
Fig. 1 is the schematic perspective view of LED lamp cooling structure one preferred embodiment of the present invention;
Fig. 2 is the schematic perspective view that cooperates with LED lamp pearl and heat carrier embodiment illustrated in fig. 1;
Fig. 3 is the perspective exploded view of Fig. 2.
The specific embodiment
In order to make technical problem to be solved by this invention, technical scheme and beneficial effect clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
Please refer to Fig. 1 to Fig. 3, preferred embodiment for LED lamp cooling structure of the present invention, this LED lamp cooling structure comprises that at least one surface has the radiator 1 of a plurality of fin 10, described radiator 1 has an air guide channel 11, and the surface of described radiator 1 is provided with at least one pore 12 that is communicated with described air guide channel 11.Like this, the heat that LED lamp pearl 2 produces in the course of the work both can be dispersed by a plurality of fin 10 on radiator surface, also can flow out via described air guide channel 11 and pore 12 formed heat dissipation channels, make more thermally equivalent of radiator structure, and improve the radiating efficiency of radiator structure greatly.
Below each part mentioned above is described in detail respectively.
Described radiator 1 can be made by the good aluminium of heat-conducting effect, copper and alloy thereof etc., and it is cylindric that its profile roughly is, similar with prior art, and the fin 10 of present embodiment also increases area to improve radiating effect as far as possible.
Described air guide channel 11 is positioned at the shaft core position of described radiator 1 and connects the entire heat dissipation body.The quantity of described pore 12 is a plurality of, and is distributed on the surface of described radiator 1.Pore 12 can be formed by machining, and its specific practice is the sheet cutter to be deep between the fin 10, and to utilize cutter that radiator 1 is cut to pore 12 and described air guide channel 11 are connected.For the ease of processing, to reduce cutting output, the cross section of air guide channel 11 is the asterism shape, and described pore 12 connects with the tip of described asterism shape.
In the present embodiment, described fin 10 comprises a plurality of along the length direction of described radiator 1 groups of fins 1A arranged in a straight line, and described groups of fins 1A circumferentially evenly distributes along described radiator 1.Described pore 12 described radiator 1 circumferentially between described groups of fins 1A, and be spaced with described fin 10 on axially at described radiator 1.
In order to make described pore 12 more unobstructed with described air guide channel 11 formed heat dissipation channels.Between described groups of fins 1A, the position of corresponding described pore 12 is provided with thermal trough 13.Like this, air guide channel 11, pore 12 and thermal trough 13 have promptly formed a unimpeded heat dissipation channel, and the heat that can in time LED lamp pearl 2 be distributed is discharged, and without making more thermally equivalent of radiator structure, and improve the radiating efficiency of radiator structure greatly.
In addition, the present invention also provides a kind of LED light fixture, and described LED light fixture comprises at least one LED lamp pearl and quantity and the corresponding radiator structure of described LED lamp pearl, and described radiator structure has above-mentioned structure.
The above only is preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of being done within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
