Abstract
The utility model discloses a light-emitting diode (LED) bulb lamp. The LED bulb lamp comprises a substrate and light beads arranged on the substrate, wherein a lampshade is arranged at the upper end of the substrate, a heat-dissipation device is arranged at the lower end of the substrate, a base body of the heat-dissipation device is cylindrical, and a plurality of heat-dissipation fins are arranged on the outer circumference of the base body in a surrounding mode. By means of the technical scheme, the structure that the heat-dissipation fins are arranged on the outer circumference of the base body in the surrounding mode is reasonable and simple, and the heat-dissipation effect is good.
Description
Technical field
The utility model relates to bulb lamp, is specifically related to a kind of LED bulb lamp.
Background technology
Long service life, the energy consumption of LED lamp is low, energy savings is remarkable, so the LED lamp has been widely used for daily life as light source, as the LED bulb lamp.Yet along with the increase of LED quantity in the LED bulb lamp and the raising of power and brightness, the heat that produces when making the work of LED lamp is unprecedented soaring.Therefore, the radiating effect that how to improve the LED bulb lamp becomes significant problem in the LED bulb lamp technology.
In the prior art, the LED bulb lamp comprises substrate, is arranged on LED lamp and heat abstractor on the substrate.When the operating illumination of LED bulb lamp, the heat that the LED lamp produces reaches heat abstractor through substrate, is distributed by heat abstractor again, because the area of dissipation of heat abstractor is limited, causes radiating effect not good, thereby influences the life-span of LED bulb lamp.
Summary of the invention
At the deficiency that prior art exists, the purpose of this utility model is to provide the LED bulb lamp of a kind of simple in structure, good heat dissipation effect and long service life.
For achieving the above object, the utility model provides following technical scheme: a kind of LED bulb lamp, comprise substrate and the lamp pearl that is arranged on the substrate, described substrate upper end is provided with lampshade, the substrate lower end is provided with heat abstractor, the matrix of described heat abstractor is the tubular setting, and the peripheral ring of matrix is provided with a plurality of fin.
By adopting technique scheme, establish a plurality of heat radiating fin structures in the substrate ring of heat abstractor and arrange rationally, simple in structure, good heat dissipation effect.
The utility model further is set to: described a plurality of fin vertically evenly distribute around the matrix periphery.By this setting, fin vertically arranges, and radiating effect is better.
The utility model also further is set to: described a plurality of fin all are wholely set with matrix.By this setting, a plurality of fin and matrix are whole, can increase the service life, and make radiating effect better.
The utility model also further is set to: described matrix and a plurality of fin are formed by the graphite material manufacturing.By this setting, the radiating effect of heat abstractor is better.
The utility model also further is set to: described substrate is ceramic substrate.By this setting, the utility model work is more reliable.
The utility model has the advantages that: the substrate ring of heat abstractor of the present utility model is provided with a plurality of fin, and vertically evenly distributes, and matrix and fin are by the graphite material manufacturing, and structure arranges rationally, and is simple in structure, good heat dissipation effect, long service life.
The utility model is described in further detail below in conjunction with specification drawings and specific embodiments.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
Referring to Fig. 1, the disclosed a kind of LED bulb lamp of the utility model, comprise substrate 1 and the lamp pearl 2 that is arranged on the substrate 1, described substrate 1 upper end is provided with lampshade 3, substrate 1 lower end is provided with heat abstractor 4, the matrix 41 of described heat abstractor 4 is the tubular setting, and the peripheral ring of matrix 41 is provided with a plurality of fin 5.
Described a plurality of fin 5 vertically evenly distributes around matrix 41 peripheries, and described a plurality of fin 5 all are wholely set with matrix 41.Fin 5 is arranged to an integral body with matrix 41, can effectively increase the service life of whole bulb.
For making the utility model radiating effect better, as preferably, the described matrix 41 of present embodiment and a plurality of fin 5 are formed by the graphite material manufacturing.
Described substrate 1 present embodiment is ceramic substrate preferably.
Above-described embodiment is to specific descriptions of the present utility model; only be used for the utility model is further specified; can not be interpreted as the restriction to the utility model protection domain, the technician of this area makes some nonessential improvement and adjusts the utility model according to the content of above-mentioned utility model and all falls within the protection domain of the present utility model.
