Abstract
The utility model provides a heat radiator of a light emitting diode (LED) bulb lamp, and belongs to the technical field of LED light emission. The heat radiator comprises a lamp holder (1) used for mounting the LED bulb lamp, and is characterized in that the lamp holder (1) is a hollow column, wherein a plurality of heat radiating fins (2) perpendicular to the hollow column are vertically and evenly distributed along the circumferential periphery of the hollow column; and a groove (3) is formed in the peripheral contour surface of each heat radiating fin (2). Compared with the prior art, the heat radiator of the LED bulb lamp has the advantages of light weight, large heat radiating area, good heat radiating effect and longer service life.
Description
Technical field
The LED bulb lamp heat radiator belongs to LED luminescence technology field, is specifically related to a kind of radiator of the LED of being applied to bulb lamp.
Background technology
Present stage, because the LED lighting engineering is progressively ripe, and to compare with conventional light source, the LED illumination has long, the advantages such as start-up time is short, energy-conservation, sound construction of life-span, so the development of LED lighting is rapid, various LED light fixtures flood the market.Wherein the LED bulb lamp occupies larger specific gravity, but its fansink designs in design is improper, and area of dissipation is less, and radiating effect is not good, and heat is piled up easily, affects the service life of LED bulb lamp.
Summary of the invention
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, provide a kind of area of dissipation large, good heat dissipation effect, the LED bulb lamp heat radiator of long service life.
The technical scheme that its technical problem that solves the utility model adopts is: this LED bulb lamp heat radiator, comprise for the lamp socket that the LED bulb lamp is installed, it is characterized in that: described lamp socket is hollow cylinder, vertically to a plurality of radiating fins perpendicular to hollow cylinder of even distribution, described each radiating fin all has groove at peripheral contoured surface along the hollow cylinder periphery.The design of radiating fin and groove makes it have maximized cooling surface area, is beneficial to heat diffusion, has better radiating effect, has prolonged the service life of radiator.
The peripheral profile of described radiating fin is connected to form by the level and smooth convex surface on top and the level and smooth concave curved surface of bottom, has groove on the level and smooth convex surface.
Described lamp socket and radiating fin are aluminum material.
Compared with prior art, the beneficial effect that the utility model has is: the heat that led light source is produced distributes by radiating fin, and have groove at the peripheral profile of radiating fin, increased area of dissipation, be conducive to heat diffusion, it is lighter to compare other heatsink weight, has better radiating effect, has prolonged service life.
Description of drawings
Fig. 1 is the utility model structural representation front view.
Fig. 2 is the utility model structural representation axonometric drawing.
Wherein: 1, lamp socket 2, radiating fin 3, groove.
Fig. 1 ~ 2nd, most preferred embodiment of the present utility model is described further below in conjunction with 1 ~ 2 pair of the utility model of accompanying drawing.
The specific embodiment
With reference to accompanying drawing 1 ~ 2: this LED bulb lamp heat radiator comprises that lamp socket 1 and radiating fin 2 are aluminum material for lamp socket 1 and radiating fin 2 that the LED bulb lamp is installed.Lamp socket 1 is hollow cylinder, and vertically to a plurality of radiating fins 2 perpendicular to hollow cylinder of even distribution, each radiating fin 2 all has groove 3 at peripheral contoured surface along the hollow cylinder periphery.Radiating fin 2 peripheral profiles are connected to form by the level and smooth convex surface on top and the level and smooth concave curved surface of bottom, have groove 3 on the level and smooth convex surface.
The design of radiating fin 2 and groove 3 makes it have maximized cooling surface area, is beneficial to heat diffusion, has better radiating effect, has prolonged the service life of radiator.
The above, it only is preferred embodiment of the present utility model, be not to be the restriction of the utility model being made other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solutions of the utility model content that do not break away to any simple modification, equivalent variations and remodeling that above embodiment does, still belongs to the protection domain of technical solutions of the utility model according to technical spirit of the present utility model.
