Description

A kind of LED lamp

Technical field

The utility model belongs to lighting field, and particularly a kind of radiating effect is the LED lamp preferably.

Background technology

LED is little because of its power, brightness is high is widely used, present common LED lamp as shown in Figure 1, comprises working of plastics 10, lampshade 20 and is located at aluminium base, led light source, lens in the lampshade 20, working of plastics 10 is positioned at the bottom of lampshade 20, is used for the LED lamp being pegged graft or being fixed in lamp socket; Lampshade 20 is generally bowl-shape, and aluminium base is fixed in the accommodation space of lampshade 20, and led light source is fixed on the aluminium base, and electrically connect, lens are located at the opening part of lampshade 20, shine out after the light that led light source is sent converges, to improve brightness of illumination.

As everyone knows, the LED lamp in actual use, therefore caloric value is very high, influences the service life of led light source, how to solve heat dissipation problem, is the research direction that industry is paid close attention to.In order to increase area of dissipation, generally all be provided with some fins 30 on the lampshade 20, these fins 30 are to utilize aluminium section bar one-body molded on lampshade 20, though this structure can improve radiating effect to a certain extent, but because this structure only depends on the surface area that increases fin 30 to accelerate distributing of heat, and fin 30 is one-body molded on lampshade 20, so the surface area of fin 30 almost do not have the space that increases, and radiating efficiency is difficult to have raising again; The somebody considers to quicken the circulation of air by increasing fan in addition, improves radiating efficiency, yet will increase the volume of LED lamp integral body like this, and is also impracticable for small-sized light fixture.

Because the analysis of front, the design people looks for another way, and develops a kind of fitting structure that can effectively improve radiating efficiency, prolong the service life of LED lamp.

The utility model content

Main purpose of the present utility model is to provide a kind of LED lamp, and it can improve radiating efficiency, prolongs the service life of LED lamp.

In order to reach above-mentioned purpose, solution of the present utility model is:

A kind of LED lamp comprises working of plastics, lampshade, aluminium base, driver and led light source, and working of plastics is positioned at the bottom of lampshade, and aluminium base and driver all are fixed in the lampshade, and led light source is located on the aluminium base, and electrically is connected with driver; The outboard row of described lampshade is furnished with the fin of plurality of single moulding, and all offers through hole on this fin.

Above-mentioned through hole is located at the same position of each fin.

Above-mentioned fin is plugged in the outside of lampshade.

The upper periphery of above-mentioned lampshade forms a circle draw-in groove, and each fin correspondence is placed in the draw-in groove.

The top of above-mentioned all fins is also detained and is established a top flat, and corresponding each fin of this top flat is provided with jack.

Above-mentioned fin is bending type.

The opening part of above-mentioned lampshade also is provided with and can converges the lens that led light source emits beam.

After adopting such scheme, the utlity model has following improvement:

(1) changes fin and the integrated structure of lampshade now, and, be fixed in the outside of lampshade again, thereby can the structure of fin self be improved, overcome in the existing structure because of the one-body molded radiator structure that can't realize with the independent moulding of fin;

(2) offer earlier through hole on fin, and then fin is arranged in the lampshade outside, the through hole between each adjacent fins forms the air channel, and air flows in this air channel, improves radiating efficiency;

Therefore (3) because fin is independent moulding, can be the structure of bending type with fin design,, thereby can in limited space, the lampshade outside, realize big as far as possible area of dissipation, the enhancing radiating effect as " S " type.

The specific embodiment

Below in conjunction with drawings and the specific embodiments structure of the present utility model is elaborated.

With reference to figure 2 and shown in Figure 5, a kind of LED lamp that the utility model provides comprises working of plastics 1, lampshade 2, driver 3, aluminium base 4 and led light source 5, and lampshade 2 is the bowl structure of semicircular ball, inside has the accommodation space of hollow, and working of plastics 1 is positioned at the bottom of lampshade 2; Driver 3 and aluminium base 4 all are positioned at the accommodation space of lampshade 2, and led light source 5 is fixed on the aluminium base 4, and electrically connect with driver 3, luminous work under the control of driver 3, as shown in Figure 4; The aforementioned existing structure that is is so repeat no more.

Improvement of the present utility model is: also be placed with some fins 6 in the outside of lampshade 2, and fin 6 is to fix with lampshade 2 after the independent moulding again, in the present embodiment, fin 6 is the outsides that are plugged on lampshade 2, specifically can be with reference to shown in Figure 6, the top week side of lampshade 2 is formed with a circle draw-in groove 21, each fin 6 can be placed in the draw-in groove 21 successively, establish a top flat 8 at the top of all fins 6 button then, corresponding respectively each fin 6 is provided with the jack 81 that can supply fin 6 to insert on this top flat 8, after assembling finished, top flat 8 can carry out effectively spacing to fin 6 like this, prevented that further it is by coming off in the draw-in groove 21; And all offer through hole 61 on each fin 6, through hole 61 is formed on the middle part of each fin 6, thereby all through holes 61 form an air channel of quickening circulation of air, and air flows in each through hole 61, and effectively distributing of accelerated heat improved radiating efficiency.

In addition, in the present embodiment, in order further to improve radiating effect, also each fin 6 is designed to bending type, can be with reference to shown in Figure 3, the cross section of fin 6 is approximate " S " type, compare the single board-type of fin in the existing structure, bigger with the contact area in the external world, thereby under the prerequisite that does not increase LED lamp own vol, the expansion area of dissipation, the service life of prolongation led light source 5.

Moreover, in order to improve the brightness of illumination of LED lamp, present embodiment is also fixed lens 7 at the opening part of lampshade 2, as Fig. 2 Fig. 4 and shown in Figure 5, top flat 8 is circular, and lens 7 correspondences are positioned at the center of top flat 8, and these lens 7 shine out after the light that led light source 5 sends can being converged again, increase brightness of illumination.

In sum, a kind of LED lamp of the utility model focuses on fin 6 independent moulding are fixed on the outside of lampshade 2 then, this structure can make that the form of fin 6 is varied, as on fin 6, offering through hole 61 in the utility model earlier,, increase circulation of air to form the air channel, improve radiating efficiency, and can easily fin 6 be designed to bending type, to increase area of dissipation, prolong the service life of led light source 5.

Above embodiment only is explanation technological thought of the present utility model; can not limit protection domain of the present utility model with this; every according to the technological thought that the utility model proposes, any change of being done on the technical scheme basis all falls within the utility model protection domain.
