Abstract
The invention discloses a lamp holder of an LED bulb. The lamp holder of the LED bulb comprises a cylindrical body and a plurality of radiating ribs, wherein the radiating ribs extend outwards from the outer wall of the cylindrical body, the sizes of the radiating ribs become larger gradually as the radiating ribs get closer to the bottom of the cylindrical body in the radial direction perpendicular to the central axis of the cylindrical body, arc transition exists between the outer edge of the bottom of the cylindrical body and the outer edges of the radiating ribs, a cylindrical heat insulation sleeve is arranged inside the cylindrical body, and a wiring duct and a plurality of fixing holes are formed in the bottom of the cylindrical heat insulation sleeve. Due to the fact that the radiating ribs are arranged on the outer wall of the cylindrical body, heat generated by the bulb can be dissipated effectively. Due to the fact that the cylindrical heat insulation sleeve is arranged inside the cylindrical body, heat conducted by the lamp holder can be isolated from the interior of the cylindrical heat insulation sleeve, and an LED driving device arranged inside the cylindrical heat insulation sleeve is protected. According to the technical scheme, the radiating effect is strengthened and the LED driving device inside the cylindrical body is protected.
Description
Technical field
The present invention relates to a kind of LED bulb, particularly a kind of lamp holder with LED bulb of heat sinking function.
Background technology
The LED bulb is in luminous process, and the temperature of bulb can raise, along with the rising of temperature, bulb can be subjected to bad influence, goes down for a long time, and the life-span of LED bulb can shorten, therefore, how to improve the radiating efficiency of LED bulb, become industry technology personnel's primary research and development emphasis.In the existing technology, the industry technology personnel adopt aluminum alloy materials at the lamp holder of making the LED bulb, simultaneously add radiating ribs at bulb, aluminum alloy materials adds that the heat that radiating ribs can effectively produce bulb distributes, but, there is shortcoming equally in metal material, that is exactly thermal conductivity, the heat that bulb distributes passes through aluminum alloy materials, conduct heat in the LED drive unit in the lamp holder, influence the normal service life of LED drive unit, thereby also influenced the service life of LED bulb.
Summary of the invention
The problem to be solved in the present invention provides a kind of good heat dissipation effect, does not have influence on simultaneously the lamp holder of LED bulb in the service life of the LED drive unit in the lamp holder again.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme: a kind of lamp holder of LED bulb, comprise tubular body and some radiating ribs, described radiating ribs stretches out from described tubular body outer wall, increase gradually bottom close tubular body along the size with the mutually perpendicular radiating ribs in the radial direction of described tubular body central shaft, be provided with the circular arc transition between described tubular body bottom outer rim and the described radiating ribs outer rim, described tubular body interior is provided with the tubular collet, and described tubular collet bottom is provided with wire casing and several fixing holes.
Improved, described tubular body and tubular collet are cylindrical shape.
Improved, adopt glue bonding between described tubular inner body wall and the tubular collet outer wall.
Improved, be " Y " font along the cross section with the mutually perpendicular radiating ribs in the radial direction of described tubular body central shaft.
Improved, the material of described lamp holder is aluminium alloy.
Beneficial effect of the present invention:
At tubular body outer wall radiating ribs is set among the present invention; the heat that can effectively bulb be produced distributes; in the tubular body; the tubular collet is set; the heat that can effectively lamp holder be conducted completely cuts off in tubular collet outside, thereby has protected the LED drive unit that is arranged on tubular collet the inside.After adopting technique scheme, the present invention has also protected the intrinsic LED drive unit of tubular when strengthening radiating effect.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described further:
Fig. 1 is the vertical view of the lamp holder of LED bulb of the present invention;
Fig. 2 is the front view of the lamp holder of LED bulb of the present invention;
Fig. 3 is the cutaway view at A-A place among Fig. 2.
The specific embodiment
Be explained and illustrated below in conjunction with the accompanying drawing of the embodiment of the invention technical scheme to the embodiment of the invention, but following embodiment is the preferred embodiments of the present invention only, is not whole.Based on the embodiment in the embodiment, those skilled in the art belong to protection scope of the present invention at following other embodiment that obtains of the prerequisite of not making creative work.
As Fig. 1 or shown in Figure 3, a kind of lamp holder of LED bulb, comprise tubular body 1 and some radiating ribs 3, described radiating ribs 3 stretches out from described tubular body 1 outer wall, along with the size of the mutually perpendicular radiating ribs in the radial direction 3 of described tubular body 1 central shaft along with increasing gradually near tubular body 1 bottom, be provided with the circular arc transition between described tubular body 1 bottom outer rim and the described radiating ribs outer rim 3, described tubular body 1 inside is provided with tubular collet 2, and described tubular collet 2 bottoms are provided with wire casing 5 and several fixing holes 4.Be provided with the circular arc transition between tubular body 1 bottom outer rim and the described radiating ribs outer rim 3, be convenient to increase bottom space, the LED substrate can be installed in the lamp holder bottom, during concrete enforcement, a LED substrate slot can also be set between circular arc transition and radiating ribs outer rim 3, can better locate the position of LED substrate, be convenient to install.Tubular collet 2 adopts the shape identical with tubular body 1, and still, size is less than tubular body 1, makes tubular collet 2 being clamped in the tubular body 1 tightly, and the material of tubular collet 2 can adopt the little ceramic material of thermal conductivity factor, asbestos shingle etc.
Described tubular body 1 and tubular collet 2 are cylindrical shape, except adopting cylindrical shape, in order to increase the aesthetic property of lamp holder, can also be squares, also can be regular polygons such as six rhombuses.
Adopt glue bonding between described tubular body 1 inwall and tubular collet 2 outer walls, adopt glue bonding, make that the combination between tubular body 1 and the tubular collet 2 is more firm.
Be " Y " font along the cross section with the mutually perpendicular radiating ribs in the radial direction 3 of described tubular body 1 central shaft, cross section can effectively increase the area of dissipation of radiating ribs 3 for the radiating ribs 3 of " Y " font.
The material of described lamp holder is aluminium alloy, adopts aluminum alloy materials, has not only reduced the quality of lamp holder, because the thermal conductivity of metal makes that the radiating effect of lamp holder is better.
Except above preferred embodiment, the present invention also has other embodiment, and those skilled in the art can make various changes and distortion according to the present invention, only otherwise break away from spirit of the present invention, all should belong to the defined scope of claims of the present invention.
