Abstract
The utility model discloses a high heat radiation LED lamp bead, comprising a light transmission cover, a light source assembly, a heat radiation housing, a driver, and a lamp socket assembly, the high heat radiation LED lamp bead is characterized in that: the heat radiation housing is provided with a plurality of outwardly-spread radiating fins. The structures and shapes of the radiating fins are the same, and the radiating fins are circumferentially uniformly distributed. Each radiating fin is in the shape of a sheet or a petal. The LED lamp bead in the utility model is provided with simple and reasonable structure, the particular heat radiation structure form of the plurality of outwardly-spread radiating fins is adopted, the structures and shapes of the plurality of radiating fins are the same, and the radiating fins are circumferentially uniformly distributed to form a heat radiation integral body. The LED lamp bead is advantageous in that, since a unified sheet or pedal heat radiation device is used, the produced heat in use of the lamp bead is uniformly spread to the periphery via heat radiation pedals, heat radiation area is enlarged, effects of uniform heat radiation and rapid heat radiation are effectively realized, formation of light spot is prevented, and the light distribution demand of a general lamp can be satisfied.
Description
Technical field
The utility model relates to a kind of LED lamp pearl, especially can quick heat radiating, and energy-efficient, the structure of the LED lamp pearl of good looking appearance belongs to the LED field of illumination lamp technology.
Background technology
At present, general lighting field adopts Halogen lamp LED pearl or traditional LED lamp pearl as light source, and Halogen lamp LED pearl service life is short, luminous efficiency is low, colour temperature is low, and causes environmental pollution easily.Existing LED lamp pearl is owing to structure problem, and it is inhomogeneous to dispel the heat, and can not cooperate the light distribution requirements of general light fixture, and forms hot spot easily.
Summary of the invention
The purpose of the utility model is exactly the defective that exists to above-mentioned prior art, and a kind of LED lamp pearl structure of good heat dissipation effect is provided.
The purpose of the utility model; To be achieved through following technical scheme: a kind of LED lamp pearl of high heat radiation; Be made up of diffuser, light source assembly, heat-dissipating casing, driving, lamp socket assembling, it is characterized in that: said heat-dissipating casing is provided with a plurality of fin to external diffusion.
Said heat-dissipating casing is by being evenly distributed and the radiator of unity of form is formed, and effectively heat radiation is whole to be one.
The planform of said fin is identical, circumferentially evenly distributes.
Said fin be shaped as sheet or flap or round needle shape.
The utility model is rational in infrastructure simple, good looking appearance, good heat dissipation effect.Employing is to the special radiator structure form of a plurality of fin of external diffusion, and the planform of a plurality of fin is identical, and circumferentially evenly distributing, it is whole to form a heat radiation.This LED lamp pearl is owing to adopt unified sheet or flap heat abstractor; The heat that produces when the lamp pearl is used is through diffusion around the uniform picture of heat radiation lobe; Enlarged area of dissipation; Can effectively realize the effect of Homogeneouslly-radiating and quick heat radiating, and can avoid forming hot spot, can satisfy the light distribution requirements of general light fixture.
