The invention discloses a heat dissipation-improved LED illuminating lamp structure, belongs to an illuminating lamp, and aims to provide an LED illuminating lamp with quick heat conduction, high heat dissipation efficiency, simple structure, low production cost and light mass. The heat dissipation improved structure comprises a shell fixed with a lamp cap at the top, an aluminum basal plate fixed in the shell and having a heat dissipation hole, multiple LED beads distributed on the bottom surface of the aluminum basal plate, and a lamp cover for closing the shell, wherein multiple heat dissipation windows are distributed on the wall of the shell; and a layer of graphene film (4) covers the surface of the aluminum basal plate (6). The heat dissipation-improved LED illuminating lamp structure is fast in heat conduction and high in heat dissipation efficiency, and is an improved LED illuminating lamp structure.
Description
Technical field
The present invention relates to a kind of LED illumination lamp, particularly relate to a kind of LED illumination lamp heat radiation modified node method, belong to lighting.
Background technology
As everyone knows, LED is called as forth generation lighting source or green light source, has the features such as energy-saving and environmental protection, the life-span is long, volume is little, can be widely used in the fields such as various instruction, display, decoration, backlight, general lighting and urban landscape.
Current LED illumination lamp by shell, be fixed in this shell with the aluminium base of louvre, be distributed in this aluminium base bottom surface some LED lamp bead, the lampshade of described shell seal is formed; In order to dispel the heat, reduce light decay, usually some radiator windows to be offered on shell wall.Although this structure is simple, have that radiating efficiency is low, light decay serious, a defect that LED lamp bead service life is short.Radiating efficiency improves to increase the mode of radiator on the surface of aluminium base in part producer for this reason, but have that complex structure, production cost are high, the quality defect such as heavily.
Summary of the invention
In order to overcome the deficiencies in the prior art, the present invention aims to provide the LED illumination lamp heat radiation modified node method that a kind of heat conduction is fast, radiating efficiency is high, structure is simple, production cost is low, quality is light.
To achieve these goals, the present invention is by the following technical solutions: it comprise top be fixed with lamp holder shell, be fixed in this shell with the aluminium base of louvre, be distributed in this aluminium base bottom surface some LED lamp bead, by the lampshade of described shell seal, shell wall is distributed with some radiator windows; The surface coverage of aluminium base has one deck graphene film.
The surface distributed of shell has some radiation ribs.
Compared with the prior art, the present invention is owing to have employed technique scheme, add on the surface of aluminium base the graphene film that one deck has good heat-conductivity (being greater than 1500W/mK), therefore effectively can improve the heat-conductive characteristic of aluminium base, avoid LED chip internal heat to concentrate; In addition, graphene film has fabulous pliability and higher mechanical strength, therefore can reduce the thickness of aluminium base, and then alleviates the weight of illuminating lamp body.Owing to adding some radiation ribs on the surface of shell, therefore effectively increase the area of dissipation of shell, improve radiating efficiency; In addition, because radiation rib can improve the Rigidity and strength of shell, therefore the size of shell can do more frivolous, be not only conducive to radiating and cooling, but also the weight of lamp body can have been alleviated further.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the A-A sectional view in Fig. 1;
Fig. 3 is the structural representation of traditional LED illumination lamp.
In figure: lamp holder 1, shell 2, radiator window 3, graphene film 4, lampshade 5, aluminium base 6, louvre 7, LED lamp bead 8, radiation rib 9.
Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, the invention will be further described:
Lamp holder 1 is fixed on the top of shell 2, the aluminium base 6 of the some louvres 7 be fixed with in this shell, and the bottom surface of this aluminium base is distributed with some LED lamp bead 8, and the lampshade 5 closed is arranged at the bottom of shell 2.Each LED lamp bead 8 is electrically connected with lamp holder 1 by the drive circuit (not shown) be fixed on aluminium base 6, and shell wall has some radiator windows 3 higher than the position distribution of aluminium base 6; In order to improve thermal conductivity, the surface coverage of aluminium base 6 has one deck graphene film 4.In order to increasing heat radiation area, improve radiating efficiency, the surface distributed of shell 2 has some radiation ribs 9.
Comparison diagram 1 Fig. 3 can find out, the present invention owing to adding graphene film 4, be therefore distributed in heat that LED lamp bead 8 on aluminium base 6 and drive circuit (not shown) produce can by graphene film 4 fast conduction cause shell 2; Surface due to this shell is provided with some radiation ribs 9, therefore, it is possible to by outside for heat rapid diffusion, improve radiating efficiency.
Claims (2)
