Abstract
The utility model discloses an LED lamp with a built-in radiator, comprising a housing, a radiator, an optical component and a power supply, wherein the optical component consists of an aluminium base circuit board, a high-power LED lamp, a waterproof ring and a lens; the housing is provided with a chimney; one end of the chimney is tightly connected with the housing or the chimney and the housing are molded into a whole at one time; the other end of the chimney is fixedly provided with the radiator; a plurality of channels are arranged among the radiator fins to lead air to smoothly flow to the other end of the chimney from one end; and the optical component is also fixed on the radiator base plate. The utility model has the advantages of good heat dissipation efficiency, long service life and the like.
Description
Technical field
The utility model relates to a kind of LED light fixture, more particularly, relates to a kind of LED light fixture of built-in radiator.
Background technology
The LED light fixture belongs to solid-state lighting lamp, and characteristics such as province's electric life length are arranged than the conventional lamp certificate, and vast potential for future development is arranged, but, because the thermal diffusivity of existing LED light fixture is not so good, makes that its service life is shorter, thereby has also limited the broader applications of LED light fixture to a certain extent.Therefore, how to solve the problem of LED light fixture heat radiation, become the bottleneck that the sector further develops.
Its radiator such as existing LED light fixture such as street lamp, Tunnel Lamp etc. usually are direct external installation and do not have shell, its objective is in order to dispel the heat better.But, oxidized because radiator is subjected to the irradiation of UV sunlight to destroy the spreader surface protective layer easily for a long time, thus easily cause radiating efficiency decline temperature to rise, shorten the life-span of LED light fixture.At present, also have its radiators such as some LED street lamps, Tunnel Lamp to be built in the shell, but its circulation of air is bad, the heat that produces during LED work is difficult to shed, and equally easily causes the temperature rising and the LED lamp life is shortened.
The utility model content
Technical problem to be solved in the utility model provides the LED light fixture of the built-in radiator of the good and long service life of a kind of radiating efficiency.
In order to solve the problems of the technologies described above, the utility model has adopted following technical scheme:
A kind of LED light fixture of built-in radiator, it comprises shell, radiator, optical module and power supply, described optical module is made up of aluminum-based circuit board, high-powered LED lamp strain, water proof ring and lens, described shell is provided with a chimney, closely linked or chimney of one end of chimney and shell and drain pan one-shot forming are as a whole, and the other end of chimney is installed with radiator.
Described radiator is made up of radiating bottom plate and a plurality of heat radiation fin, and the heat radiation fin is fixed on the radiating bottom plate, evenly leaves the gap between each heat radiation fin, forms a plurality of air ducts, the top optical module that also is fixed with of radiating bottom plate.
Described shell is provided with a plurality of air-vents.
Described water proof ring is located between lens and the radiating bottom plate.
The utility model is owing to adopted said structure, when the LED light fixture moves, the heat that LED produces is delivered on the aluminum-based circuit board earlier, be delivered on the radiating bottom plate by aluminum-based circuit board again, scribbling thermal grease between aluminium base and radiating bottom plate. the temperature on the radiating bottom plate contacts with the air large tracts of land by the heat radiation fin on the base plate and passes to air, and heated air moves upward because of density reduces.So, negative pressure appears in the chimney, and the cold air of bottom has been inhaled, and stack effect occurred, and heated air constantly rises, and cold air has constantly been inhaled.And these cold airs are come in by passage between the heat radiation fin, and cold and hot exchange more quickly and effectively.This its radiating efficiency of cold and hot air guided motion that produces because of stack effect is than the LED light fixture radiating efficiency height of external radiator.
In addition, in the enclosure built-in because of radiator, can protect radiator not to be scratched, not by solar ulatraviolet radiation and the deface protective layer, thus the service life that can improve the LED light fixture.
After the detailed description of reading embodiment of the present utility model in conjunction with the accompanying drawings, it is clearer that characteristics of the present utility model and advantage will become.

The specific embodiment
With the specific embodiment the utility model is described in further detail below, but should illustrates, protection domain of the present utility model is not limited only to this.
As shown in figure 15, a kind of LED light fixture of built-in radiator, it comprises shell 1, radiator 2, optical module 3 and power supply 4, optical module 3 is made up of aluminum-based circuit board 34, high-powered LED lamp strain 31, water proof ring 32 and lens 33, shell 1 is provided with a chimney 5, one end of chimney 5 and shell 1 are closely linked or chimney 5 is as a whole with shell 1 one-shot forming, and the other end of chimney 5 is installed with radiator 2.Radiator 2 is made up of radiating bottom plate 21 and a plurality of heat radiation fin 22, and heat radiation fin 22 is fixed on the radiating bottom plate 21, evenly leaves the gap between each heat radiation fin, forms a plurality of air ducts, is fixed with optical module 3 above the radiating bottom plate 21.Shell 1 is provided with a plurality of air-vents 11.Water proof ring 32 is located between lens 33 and the radiating bottom plate 21.When LED lamp strain 31 work, the heat of its generation is delivered to earlier on the aluminum-based circuit board 34, be delivered on the radiating bottom plate 21 by aluminum-based circuit board 34 again, temperature on the radiating bottom plate 21 contacts with the air large tracts of land by heat radiation fin 22 and passes to air, and heated air moves upward because of density reduces.So, negative pressure appears in the chimney 5, and the cold air of bottom has been inhaled, and stack effect occurred, and heated air constantly rises, and cold air has constantly been inhaled.And these cold airs are to come in by the passage between the heat radiation fin 22, and cold and hot exchange more quickly and effectively.This its radiating efficiency of cold and hot air guided motion that produces because of stack effect is than the LED light fixture radiating efficiency height of external radiator.In addition, the structure of radiator can have multiple, and requirement can allow air smoothly by the heat radiation fin, as shown in Figure 4, has exemplified another version of radiator.
Though described embodiment of the present utility model in conjunction with the accompanying drawings; but those skilled in the art can make within the scope of the appended claims and make various distortion or modification; as long as be no more than the described protection domain of claim of the present utility model, all should be within protection domain of the present utility model.
