Description
Technical field
The utility model relates to the heat spreader structures that is applicable to the use of ball bubble shape LED lamp.
Background technology
In the use procedure of ball bubble shape LED lamp, dispel the heat in the rear end that conventionally fin is arranged on to ball bubble shape LED lamp lamp socket, or ball bubble shape LED lamp is laid fin around.The heat that fin can only upload output to LED lamp heat conduction chip is set in the rear end of ball bubble shape LED lamp lamp socket and dispels the heat, but the heat that field of illumination is sent dispels the heat.It is better that ball bubble shape LED lamp is laid radiation effect of fin around, but because ball bubble shape LED lamp only has field of illumination to be foremost exposed, reduced luminous flux, the effect of impact illumination.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of ball bubble shape LED lamp radiator, not only good heat dissipation effect, and radiating rate is fast, and ball bubble shape LED lamp field of illumination is large, has guaranteed illuminating effect.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: ball bubble shape LED lamp radiator, comprise discoidal LED lamp lamp socket, the upper bottom surface of described LED lamp lamp socket is the joint face of fixing use, the bottom surface of LED lamp lamp socket is LED lamp installed surface, bottom surface edge along LED lamp lamp socket is laid with some fins, fin one end is fixedly connected on the bottom surface of LED lamp lamp socket, the fin other end is free end to downward-extension, the described LED lamp lamp socket center of circle is acute angle to perisporium bearing of trend and fin, described fin is outside outstanding arc sections on the bottom surface that is fixedly connected on LED lamp lamp socket, fin extends to free end, the circular arc of fin narrows as fillet portion.The thermal source that discoid LED lamp lamp socket makes the fin that is arranged in LED lamp lamp socket edge steep the evolution of heat of shape LED lamp apart from ball is equidistant, has guaranteed Homogeneouslly-radiating.The described LED lamp lamp socket center of circle is acute angle to perisporium bearing of trend and fin, can increase ball bubble shape LED lamp field of illumination and be exposed to outer area, good illumination effect.Outwards outstanding arc sections has increased the area of dissipation of fin under the prerequisite that does not change number of fins, has accelerated radiating rate.
Preferably, the arc sections of described fin is placed with several through holes.Through hole has further strengthened the area that fin contacts with air, has accelerated radiating rate, and through hole is arranged on arc sections, and arc sections, near LED lamp lamp socket, approaches thermal source, can accelerate heat radiation.
Preferably, the described LED lamp lamp socket center of circle to perisporium bearing of trend and angle that fin is between 45 °-60 °.Because fin 2 radiating effect when larger with the dihedral angle angle of the bottom surface of LED lamp lamp socket wants better, when fin 2 is 90 ° with the dihedral angle of the bottom surface of LED lamp lamp socket, radiating effect is best, but for guaranteeing the luminous flux of ball bubble shape LED lamp, need to expand the area of ball bubble shape LED lamp surround as far as possible.When the described LED lamp lamp socket center of circle is when perisporium bearing of trend and angle that fin is are between 45 °-60 °, the dihedral angle angle of the bottom surface of fin and LED lamp lamp socket is between 120 °-135 °.Not only field of illumination increases, and good heat dissipation effect.
Preferably, described fin is equidistantly arranged, and described fin is arranged within the scope of 20-28 sheet.Number of fins is moderate, not only good heat dissipation effect, and can be not too much because of number of fins, cause waste of material.
Preferably, the area of described arc sections be fillet portion 2-3 doubly.The arc sections of fin approaches LED lamp lamp socket, and the area of arc sections is conducive to greatly accelerate heat radiation, and good heat dissipation effect.The area of described arc sections also can not be excessive, otherwise the inconvenience that can cause LED lamp radiator to install, and need a larger lampshade to mate, so that the area of arc sections is the 2-3 of fillet portion is doubly suitable.
Adopt after technique scheme, the utlity model has following advantage:
Described LED lamp lamp socket is discoid, and the thermal source that makes the fin that is arranged in LED lamp lamp socket edge steep the evolution of heat of shape LED lamp apart from ball is equidistant, has guaranteed Homogeneouslly-radiating.The described LED lamp lamp socket center of circle is acute angle to perisporium bearing of trend and fin, has increased ball bubble shape LED lamp field of illumination and has been exposed to outer area, good illumination effect.Outwards outstanding arc sections has increased the area of dissipation of fin under the prerequisite that does not change number of fins, has accelerated radiating rate.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described further:
Fig. 1 is perspective view of the present utility model;
Fig. 2 is the top-down cutaway view of Fig. 1;
Fig. 3 is fin structure schematic diagram.
The specific embodiment
As Figure 1-3, ball bubble shape LED lamp radiator, comprise discoidal LED lamp lamp socket 1, the upper bottom surface of described LED lamp lamp socket 1 is the joint face of fixing use, the bottom surface of LED lamp lamp socket 1 is LED lamp installed surface, along the bottom surface edge of LED lamp lamp socket 1, is laid with some fins 2, and fin 2 one end are fixedly connected on the bottom surface of LED lamp lamp socket 1, fin 2 other ends are free end to downward-extension, and described LED lamp lamp socket 1 center of circle is acute angle to perisporium bearing of trend and fin 2.Increase ball bubble shape LED lamp field of illumination and be exposed to outer area, good illumination effect.Because fin 2 radiating effect when larger with the dihedral angle angle of the bottom surface of LED lamp lamp socket wants better, when fin 2 is 90 ° with the dihedral angle of the bottom surface of LED lamp lamp socket, radiating effect is best, but for guaranteeing the luminous flux of ball bubble shape LED lamp, need to expand the area of ball bubble shape LED lamp surround as far as possible.As a kind of preferred embodiment, described LED lamp lamp socket 1 center of circle to perisporium bearing of trend and fin 2 be angle between 45 °-60 °.The dihedral angle angle of the bottom surface of fin 2 and LED lamp lamp socket 1, between 120 °-135 °, has not only increased field of illumination, and good heat dissipation effect.
Referring to Fig. 3, described fin 2 is outside outstanding arc sections on the bottom surface that is fixedly connected on LED lamp lamp socket 1, and fin extends to free end, and the circular arc of fin 2 narrows as fillet portion.The shape of fin does not need to increase the size of lampshade.The area of described arc sections is 2-3 times of fillet portion.The arc sections of fin approaches LED lamp lamp socket, and the area of arc sections is conducive to greatly accelerate heat radiation, and good heat dissipation effect.The area of described arc sections also can not be excessive, otherwise the inconvenience that can cause LED lamp radiator to install, and need a larger lampshade to mate, so that the area of arc sections is the 2-3 of fillet portion is doubly suitable.As the optimal way of the present embodiment, the arc sections of described fin 2 is placed with several through holes 21.Through hole 21 has been accelerated the convection current of fin 2 with air, has accelerated heat radiation.Through hole 21 is arranged on arc sections, and arc sections, near LED lamp lamp socket 1, approaches thermal source, can accelerate heat radiation.
For making heat radiation evenly, described fin 2 is equidistantly arranged.Described fin 2 is arranged within the scope of 20-28 sheet not only good heat dissipation effect, and can too much not cause because of fin 2 quantity the waste of material.
Except above preferred embodiment, the utility model also has other embodiment, those skilled in the art can make various changes and distortion according to the utility model, only otherwise depart from spirit of the present utility model, all should belong to the defined scope of the utility model claims.
