Abstract
The utility model discloses an LED (light-emitting diode) lamp, which comprises a shell and a light source module arranged in the shell, wherein the light source module comprises a power source driving module, both sides of the power source driving module are respectively provided with a cooling fin and an LED lamp bead externally provided with a light transmission shade, the shell comprises an upper shell and a lower shell, and a heat dissipation layer is arranged between the upper shell and the lower shell. Heat circulation is formed between the heat dissipation layer and the lower shell, and in addition, heat circulation is also formed between the heat dissipation layer and the upper shell, so the heat exchange is more sufficient, and the heat dissipation effect is better.
Description
Technical field
The present invention relates to a kind of lamp, relate in particular to a kind of LED lamp.
Background technology
Present LED lamp mainly is that the radiator by an integral body directly exposes help the LED heat radiation in air, forms the light fixture of a kind of " bareing " like this, because radiator all is an aluminum alloy material, aluminium alloy is directly exposed to outdoor corrosion easily.In order to alleviate the extent of corrosion of aluminium alloy, a lot of LED light fixtures all add a shell in the radiator outside, break up hot hole or radiating groove above the shell again, can significantly alleviate the corrosion of radiator like this.But only be unsatisfactory, still can not solve the radiating effect of LED lamp well by louvre or its radiating effect of radiating groove.
Summary of the invention
The invention provides a kind of LED lamp that can greatly improve radiating effect.
Technical scheme of the present invention is: a kind of LED lamp, comprise shell and installation light source module within it, the light source module comprises electric power driving module, the both sides of electric power driving module are respectively equipped with fin and its outer LED lamp pearl that is provided with diffuser, shell comprises upper shell and lower house, is provided with heat dissipating layer between upper shell and the lower house.
As of the present invention a kind of preferred, upper shell and lower house are provided with louvre.
As of the present invention a kind of preferred, upper shell is hemispherical, and lower house is truncated cone-shaped.
As of the present invention a kind of preferred, also be connected with the inlet wire pipe on the lower house, the inlet wire pipe is hinged with hub.
As of the present invention a kind of preferred, fin is the 4-32 sheet, and the spacing between the fin is 3-20mm.
As of the present invention a kind of preferred, heat dissipating layer includes the several columns that connect upper shell and lower house, forms the heat radiation chamber between the adjacent upright posts.
In sum, the present invention has the following advantages:
1, the present invention is designed to the shell of LED lamp to be made up of upper shell and lower house, and between is provided with heat dissipating layer, so formed a thermal cycle between heat dissipating layer and the lower house, also formed a thermal cycle in addition between heat dissipating layer and the upper shell, heat exchange is more abundant like this, and radiating effect is better.
2, the present invention also is provided with the hub hinged with the inlet wire pipe, like this hub just can regulate and the inlet wire pipe between angle, the convenient wiring and installation.
3, quantity and the spacing between the fin, the radiating effect ideal under the situation that materials are saved like this of fin that the present invention is also preferred.
Description of drawings
Fig. 1 is a schematic diagram of the present invention;
Fig. 2 is the schematic diagram of shell;
Fig. 3 is the schematic perspective view of light source module;
Fig. 4 is the upward view of Fig. 3.
Among the figure, 1, shell; 2, light source module; 3, louvre; 4, heat dissipating layer; 1a, upper shell; 1b, lower house; 2a, electric power driving module; 2b, fin; 2c, lamp pearl; 2d, diffuser; 4a, column; 4 b, heat radiation chamber; 1b1, inlet wire pipe; 1b2, hub.
The specific embodiment
The invention will be further described with embodiment below in conjunction with accompanying drawing.
Shown in Fig. 1 to 4, a kind of LED lamp, comprise shell 1 and installation light source module 2 within it, light source module 2 comprises electric power driving module 2a, the fin 2b that it is 10mm that the both sides of electric power driving module 2a are respectively equipped with 24 sheet spacings and its outer LED lamp pearl 2c that is provided with diffuser 2d, shell 1 comprises the lower house 1b of hemispheric upper shell 1a and truncated cone-shaped, is provided with heat dissipating layer 4 between upper shell 1a and the lower house 1b.Also be provided with louvre 3 on upper shell 1a and the lower house 1b.Also be connected with inlet wire pipe 1b1 on the lower house 1b, inlet wire pipe 1b1 is hinged with hub 1b2.Heat dissipating layer 4 includes the 10 root post 4a that connect upper shell 1a and lower house 1b, forms heat radiation chamber 4 b between the adjacent upright posts 4a.
As shown in Figure 2, when lamp pearl 2c electrified light emitting generation heat, heat is passed on the fin 2b so, and the heat of fin 2b is dispersed in the inner air of shell 1.The heat exchange situation of lower house 1b is as follows: hot-air is discharged outward by bottom and the heat dissipating layer 1c of the louvre on the lower house 1b 3, lower house 1b, and cold air replenishes into from the bottom of heat dissipating layer 1c and lower house 1b simultaneously, so forms a heat exchange; The heat exchange situation of upper shell 1a is as follows: hot-air overflows from louvre 3 and the heat dissipating layer 1c of upper shell 1a, and cold air replenishes into feasible another heat exchange that forms again from louvre 3 and the heat dissipating layer 1c of upper shell 1a simultaneously.Cold and hot air so circulates, and the heat on the fin 2b is continued to take away like this, and the temperature of whole light source module 2 is well controlled within reasonable range.
More than explanation only is an explanation of the invention, make enforcement this programme that those of ordinary skills can be complete, but be not limitation of the present invention, those skilled in the art can make the modification that does not have creative contribution to present embodiment as required after reading this specification, for example the shape with upper shell 1a and lower house 1b changes cube or elliposoidal into, or the power of restriction electric power driving module 2a, these all are not creative modifications.But as long as in claim scope of the present invention, all be subjected to the protection of Patent Law.
