Abstract
The invention provides an internal heat sink which is a transparent tube made of transparent materials. The internal heat sink is placed inside a bulb shell of an LED lamp bulb and fixed to a lamp holder of the LED lamp bulb. The transparent tube made of the transparent materials serves as the internal heat sink, and light-emitting elements of the LED lamp bulb formed by assembling lamp filaments are installed in the surface or grooves of the transparent tube, so that the transparent tube has a larger superficial area, heat can be radiated around in a mode that heat conduction, heat radiation, heat convection and the like are combined, temperature rise of the light-emitting elements can be further lowered, the problem of heat sink (heat dissipation) of a traditional method is solved, and combination properties, such as the luminous efficiency, the light retention rate and the service life of the assembled lamp bulb, are effectively guaranteed.
Description
Technical field
The present invention relates to a kind of LED heat sink, particularly a kind of interior heat sink.
Background technology
Adopt the LED lamp bar of COB encapsulation to be assembled in clear lamp cell-shell some, the so-called filament LED bulb of making, not only have the warm tones colour temperature identical with conventional incandescent, and its luminous efficiency and index of aging be considerably beyond the index of incandescent lamp, after replacing, energy-saving efficiency is remarkable.The LED bulb that uses 2 to 4 filament LED assemblings, is filled with inert gas in bulb housing in it.Inert gas has not only been protected the luminous of LED own, and has reduced the temperature of LED by convection effect, and light efficiency reaches 120Lm/W left and right, the conventional incandescent of alternative 15w-40w.But test shows, when using when more than 6 or 6 filament LED is assembled into LED bulb, luminous efficiency has declined 10 ~ 20%, and reason is that the convection current of inert gas has been not enough to take away more heat; Along with the increase of LED lamp bar encapsulation number, the heat radiation contradiction of whole lamp is more aobvious outstanding, and light efficiency will further decline, and be difficult to substitute the conventional incandescent of the above power of the more 60w of use amount.And in LED lamp, only have outer heat sink help heat radiation at present, but its radiating efficiency is low, still can not address the above problem.
Summary of the invention
Technical problem to be solved by this invention is for the deficiencies in the prior art, and a kind of heat sink (heat radiation) problem that can solve conventional art is provided, and improves the interior heat sink of the combination properties such as luminous efficiency, light sustainment rate and life-span.
Technical problem to be solved by this invention is to realize by following technical scheme, and the present invention is a kind of interior heat sink, is characterized in: this interior heat sink transparent pipe for being made up of transparent material.
Described interior heat sink in, described transparent pipe is cone-shaped or column, its cross section be shaped as circle, ellipse, triangle or polygon.Therefore its upper and lower diameter can be identical or different, and wall thickness also can be inhomogeneous.
Described interior heat sink in, have some grooves along the axial inner surface of transparent pipe or outer surface.Groove not only can be fixed the light-emitting component of LED bulb, also increases thus heat conducting contact-making surface; Transparent pipe by having a high surface area more to surrounding radiation, further reduces the temperature rise of light-emitting component by heat.
Described interior heat sink in, described groove is uniformly distributed along the circumferential direction of transparent pipe.
Described interior heat sink in, described groove be shaped as circular arc, trapezoidal or rectangle, when groove is circular arc, its diameter is 0.3mm～15mm.
Described interior heat sink in, described transparent pipe is glass tube or plastic tube.Glass tube can be that quartz glass tube, borosilicate glass tube, microcrystal glass tube or common soda-lime glass etc. are applicable to glass tube of the present invention.
Described interior heat sink in, the caliber of described transparent pipe is 2-200mm, wall thickness is 0.1-10mm, length is 10-300mm.Its surface area size and wall thickness have determined the size of heat sink (heat radiation) ability, determine the different capacity of bulb.
Described interior heat sink in, above-mentioned interior heat sink purposes in filament LED bulb described in any one.
According to above-mentioned purposes, in this interior heat sink cell-shell that is placed in LED bulb, and be fixed on the lamp socket of LED bulb.
Compared with prior art, the present invention by the transparent pipe made by transparent material as interior heat sink, the light-emitting component of filament LED bulb is contained in the surface or groove of transparent pipe, because transparent pipe has larger surface area, can be by heat by combinations such as hot conduction, heat radiation and thermal convection currents to surrounding radiation, and then can further reduce the temperature rise of light-emitting component, solve heat sink (heat radiation) problem of conventional method, the combination properties such as effective luminous efficiency, light sustainment rate and life-span that ensures the bulb of assembling.
