The LED lamp heat radiator has the advantages that the heat radiation speed is high, the heat radiation effect is good, in addition, the illumination area of a bulb type LED lamp is increased, and the illumination effect is good.
Description
Technical field
The utility model relates to a kind of LED lamp heat spreader structures.
Background technology
The radiator of existing ball bubble shape LED lamp only arranges fin at the perisporium of LED lamp base, for heat radiation.But there is heat at the back at LED lamp base, cannot dissipate rapidly heat, easily cause the aging and light decay of LED lamp base.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of LED lamp radiator, and radiating rate is fast, good heat dissipation effect, and increased ball bubble shape LED lamp lighting area, good illumination effect.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: LED lamp radiator, comprise LED lamp base, the bottom surface of LED lamp base is LED lamp installed surface, on the upper bottom surface of described LED lamp base, be provided with several radiating tubes, the periphery wall of LED lamp base is connected with several radiating fins towards the upper bottom surface direction of LED lamp base.
Preferably, described radiating fin is the narrow shape of bottom wide upper portion, bottom is sector structure, top is strip structure, one end of described strip structure is towards the upper bottom surface of LED lamp base, radius and the strip structure of described sector structure are bonding, and down, and the fan arc of described sector structure arranges another of sector structure radius outwardly.
Preferably, the sector structure of described radiating fin arranges down radius tilt and with LED lamp base bottom surface in obtuse angle.
Preferably, described radiating fin surface is the concavo-convex spacer structure of strip.
Preferably, along the convex-concave surface of the sector structure of radiating fin, be provided with several through holes.
Preferably, LED lamp base is circular, and described radiating fin is arranged within the scope of 28-36 and along the periphery wall equidistant placement of LED lamp base.
Adopt after technique scheme, the utlity model has following advantage:
Be arranged on the heat that on the periphery wall of LED lamp base, radiating fin has dispelled the heat on LED lamp base perisporium effectively, the radiating tube being arranged on LED lamp base upper bottom surface has further expanded area of dissipation, the all directions of LED lamp base can effectively be dispelled the heat, rapid heat dissipation, good heat dissipation effect.
Radius that the sector structure of described radiating fin arranges down tilt and with LED lamp base bottom surface in obtuse angle.Expand the angle of LED light photograph, guaranteed the luminous flux of ball bubble shape LED lamp, guaranteed illuminating effect.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described further:
Fig. 1 is the utility model longitudinal sectional view;
Fig. 2 is the utility model upward view;
Fig. 3 is the partial sectional view of the utility model radiating tube;
Fig. 4 is the structural representation of the utility model radiating fin.
The specific embodiment
As Figure 1-3, LED lamp radiator, comprise LED lamp base 1, the bottom surface of LED lamp base 1 is LED lamp installed surface, on the upper bottom surface of described LED lamp base 1, be provided with several radiating tubes 3, the periphery wall of LED lamp base 1 is connected with several radiating fins 2 towards the upper bottom surface direction of LED lamp base 1.At the periphery wall of LED lamp base 1, connect radiating fin 2 and dispel the heat, and on the upper bottom surface of LED lamp base 1, radiating tube 3 is also set, increased area of dissipation, accelerated radiating rate.Partial sectional view referring to 3 radiating tubes can know, radiating tube 3 inner hollow structures, have strengthened area of dissipation, have further accelerated radiating rate.The lamp base of LED described in the present embodiment 1 is applicable to install ball bubble shape LED lamp.
Referring to Fig. 4, in this preferred embodiment, described radiating fin 2 is the narrow shape of bottom wide upper portion, bottom is sector structure, top is strip structure, and one end of described strip structure is towards the upper bottom surface of LED lamp base 1, and radius and the strip structure of described sector structure are bonding, down, and the fan arc of described sector structure arranges another of sector structure radius outwardly.Sector structure is laid along the periphery wall of LED lamp base 1, can not affect the installation of LED lamp, and has expanded the area of LED lamp illumination, good illumination effect.Because radiating fin 2 is when being 90 ° with the upper bottom surface of LED lamp base 1, radiating effect the best, so one end of described strip structure is towards the upper bottom surface of LED lamp base.As preferably, the area of described sector structure is doubly comparatively suitable at the 3-5 of strip structure.In the situation that not increasing radiating fin 2 quantity, increased area of dissipation, accelerated radiating rate.
As a kind of preferred embodiment, LED lamp base 1 is circular, and described radiating fin 2 is arranged within the scope of 28-36 and along the periphery wall equidistant placement of LED lamp base 1, specifically as shown in Figure 2.Radiating fin quantity is moderate, and not only good heat dissipation effect also can not cause the waste of material.LED lamp base 1 is the periphery wall equidistant placement of circle and LED lamp base 1, makes more to dispel the heat evenly.
For further expanding ball bubble shape LED lamp, be exposed to outer lighting area, the radius that the sector structure of described radiating fin 2 arranges down tilt and with LED lamp base 1 bottom surface in obtuse angle, good illumination effect.
In this preferred embodiment, described radiating fin 2 surfaces are the concavo-convex spacer structure of strip, have increased the area of radiating fin in the situation that not increasing radiating fin 2 quantity, have accelerated radiating rate.Further, along the convex-concave surface of the sector structure of radiating fin 2, several through holes 21 are set, by through hole 21, accelerate the convection current of radiating fin 2 and air, accelerate heat radiation.
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.
