Description
Technical field
The utility model relates to LED light source technical field, particularly a kind of LED silk bulb lamp and radiator thereof.
Background technology
LEDbulb lamp is the bulb shapes-spherical that outward appearance adopts people and has been accustomed to, and internal light source adopts the lighting of LED chip, due to its energy-conserving and environment-protective, long service life and be subject to people's favor, and substitutes conventional incandescent bulb gradually.
Traditional LEDbulb lamp mainly comprises lampshade, pedestal and lamp holder, in pedestal, driving power is set, LED chip is generally fixed on substrate, substrate is fixed on pedestal, described pedestal adopts metal material usually, except playing a supporting role, a main thermolysis, therefore in order to reach desirable radiating effect, pedestal generally designs very large, and this not only makes the volume of lamp become large, seem heavy, add cost of material, and pedestal can block the light that LED chip sends, the lighting angle of restriction lamp.
Existing a kind of LED silk, by one group of LED chip encapsulation on the transparent substrate, stitch is drawn respectively in two ends, access dc source just can as tungsten filament full angle luminescence, by these LED silks with series connection, mode that is in parallel or connection in series-parallel combination is fixed on stem stem, stem stem to be arranged in cell-shell and to be tightly connected with cell-shell, inert gas is filled as protective gas and heat-conducting medium in cell-shell, LED silk is driven by LED drive power, driving power is placed in lamp holder, lamp holder is fixedly connected with cell-shell again, then to make can full angle luminous, and there is no the LED silk bulb lamp of cooling base, overcome the defect of traditional LEDbulb lamp.But this bulb lamp only relies on inert gas to dispel the heat, heat dispersion is unsatisfactory, the exploitation of low-power LED lamp silk bulb lamp can only be met, and power is once do large, the heat that LED silk produces cannot shed in time, and the heat assembled thereon just easily causes cause thermal damage and the light decay of LED, affects the service life of bulb lamp, which limits the innovative design of LED silk bulb lamp outward appearance and structure, be difficult to meet its development requirement.
Utility model content
Technical problem to be solved in the utility model is to overcome the problems referred to above, and provide that a kind of profile is light and handy, cost of manufacture is low, the LED silk bulb lamp of perfect heat-dissipating, long service life and radiator thereof.
In the utility model, the technical scheme of LED silk bulb lamp is:
A kind of LED silk bulb lamp, comprise cell-shell, stem stem, lamp holder, driving power and some LED silks, described LED silk distributes around stem stem, inert gas is filled with in described cell-shell, it is characterized in that: arrange radiator between LED silk and stem stem, this radiator is the endless metal aluminium with hollow bulb, and described hollow bulb is cylindrical hole, radiator is set in outside stem stem by this cylindrical hole, and is fixed on stem stem by heat conductive silica gel.The radiator of endless metal aluminium is arranged between LED silk and stem stem, and the thermal conductivity of aluminium is good, heat radiator is fast, in the course of work of bulb lamp, most of heat that LED silk produces first passes to this radiator, be transmitted to cell-shell surface by inert gas again and be dispersed in the middle of air, fraction heat is directly conducted by inert gas, therefore the heat that LED silk produces can shed rapidly, thus effectively reduce cause thermal damage and the light decay of the LED caused due to excessive caloric value, effectively extend the service life of LED silk bulb lamp.This radiator volume is little, and consumptive material is few, and cost is low, and is arranged in cell-shell, can not affect the outward appearance of bulb lamp, to the outward appearance of bulb lamp and the more innovative design space of structure.
Further, the aperture of cylindrical hole described in the utility model is greater than the external diameter of stem stem, namely leaves space between radiator and stem stem, and described heat conductive silica gel is filled in this gap.
Further, the thickness of endless metal aluminium described in the utility model is up-narrow and down-wide, and its appearance profile is truncated cone.In order to realize full angle luminescence better, LED silk is often obliquely installed around stem stem with certain angle, and its upper end is near stem stem, and lower end is away from stem stem, and therefore fansink designs becomes up-narrow and down-wide structure, is more conducive to the conduction of heat on LED silk.
Further, radiator described in the utility model is made up of two pieces of symmetrical semi-circular aluminium blocks.
In the utility model, the technical scheme of the radiator of LED silk bulb lamp is:
A kind of radiator of LED silk bulb lamp, it is characterized in that: this radiator is the endless metal aluminium with hollow bulb, be made up of two pieces of symmetrical semi-circular aluminium blocks, described hollow bulb is cylindrical hole, this cylindrical hole is used for the stem stem of sheathed LED silk bulb lamp, and the aperture of cylindrical hole is greater than the external diameter of stem stem; The thickness of this endless metal aluminium is up-narrow and down-wide, and its appearance profile is truncated cone.
The beneficial effects of the utility model are: 1, endless metal aluminium radiator can absorb rapidly the heat that LED silk produces, be transmitted to cell-shell surface by inert gas again to distribute, avoid the gathering of heat on LED silk, thus effectively reduce cause thermal damage and the light decay of the LED caused due to excessive caloric value, in the service life of effective prolongation LED silk bulb lamp, this just allow for the exploitation of high-powered LED lamp silk bulb lamp; 2, the profile of this LED silk bulb lamp is light and handy, low cost of manufacture.
