Description

The LED lamp

Technical field

The utility model relates to the lighting apparatus field, is specifically related to a kind of LED lamp.

Background technology

As shown in Figure 1, the LED lamp of prior art comprises interconnective lamp holder 1 and lamp body 2, but the led light source on the LED lamp lamp body 2 of prior art is planar structure, and the general directionality of the light that sends is stronger, often cause shadow surface less, illumination functions is limited to.And because the internal circuit operation can gather certain heat, but the LED lamp of prior art lacks effective radiator structure, cause the LED lamp often to cause shorten the service life of internal electronic element owing to overheated easily, influence the use of LED lamp.

The utility model content

The technical problems to be solved in the utility model provide a kind of luminous evenly, perfect heat-dissipating, long service life, LED lamp simple in structure, with low cost.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is:

A kind of LED lamp comprises interconnective lamp holder and lamp body, and described lamp body is provided with lampshade, is provided with the pedestal that is tubular structure in the described lamp body, is equipped with wiring board on the side of described pedestal and the bottom, and described wiring board is provided with led light source.

As further improvement in the technical proposal:

The cross section of described pedestal is polygon.

The lower end of described pedestal is provided with ventilation orifice, and the inner chamber of described pedestal is provided with the heat radiation leaf-teeth of arranging along the axis direction of described pedestal, and the top of described lamp body is provided with the exhaust of hot air groove, the intracavity inter-connection of described exhaust of hot air groove and described pedestal.

The top of described lamp body is provided with fin.

Described fin is the radial top that is sheathed on described lamp body.

The utlity model has following advantage:

1, the utility model comprises interconnective lamp holder and lamp body, lamp body is provided with lampshade, be provided with the pedestal that is tubular structure in the lamp body, be equipped with wiring board on the side of pedestal and the bottom, wiring board is provided with led light source, have luminous evenly, long service life, advantage simple in structure, with low cost.

2, the utility model is further by three kinds of improvement: 1) inner chamber of pedestal further is provided with the heat radiation leaf-teeth of arranging along the axis direction of described pedestal; 2) top of lamp body further is provided with the exhaust of hot air groove, the intracavity inter-connection of described exhaust of hot air groove and described pedestal; 3) top of lamp body further is provided with fin.By above-mentioned improvement, can strengthen the radiating effect of LED lamp, have the advantage of good heat dissipation effect, long service life.

The specific embodiment

Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention are made more explicit defining.

As Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5, shown in, the LED lamp of present embodiment comprises interconnective lamp holder 1 and lamp body 2, lamp body 2 is provided with lampshade 21, be provided with the pedestal 22 that is tubular structure in the lamp body 2, be equipped with wiring board 23 on the side of pedestal 22 and the bottom, wiring board 23 is provided with led light source 24.Since be equipped with wiring board 23 on the side of pedestal 22 and the bottom, the planar structure of therefore relative prior art, the led light source 24 of present embodiment constitutes tubular structures, and more even light emission is disperseed.

As shown in Figure 6 and Figure 7, the cross section of the pedestal 22 of present embodiment is hexagon.Circle or other polygon also can be adopted as required in the cross section of this outer frame 22.

As shown in Figure 6 and Figure 7, in the present embodiment, the lower end of pedestal 22 is provided with ventilation orifice 221, and the inner chamber of pedestal 22 is provided with the heat radiation leaf-teeth of arranging along the axis direction of pedestal 22 25, the top of lamp body 2 is provided with exhaust of hot air groove 26, the intracavity inter-connection of exhaust of hot air groove 26 and pedestal 22.The ventilation orifice 221 of present embodiment is located on the wiring board 23 of pedestal 22 lower ends, also can directly ventilation orifice 221 be opened on the pedestal 22 in addition.

As Fig. 2 and shown in Figure 8, the top of lamp body 2 is provided with fin 27, and fin 27 can be better distributes the heat of LED lamp.The fin 27 of present embodiment is the radial top that is sheathed on lamp body 2, better heat-radiation effect.

As shown in Figure 9, the LED lamp of present embodiment is in the operating room, cold air is entered in the lampshade by lampshade 21 tops, ventilation orifice 221 by pedestal 22 lower ends enters in the pedestal 22 again, contact cooling with the heat radiation leaf-teeth 25 in the pedestal 22, finally get rid of from the exhaust of hot air groove 26 on lamp body 2 tops, utilize the principle that is similar to chimney, the principle of namely utilizing hot-air to rise can effectively realize the heat radiation to the LED lamp.
