Abstract

The invention discloses a screw lamp cap for heat dissipation. The screw lamp cap comprises a metal screw casing, and a ceramic lamp cap screwed in the casing, wherein the seam between the metal screw casing and the ceramic lamp cap is filled with a thermal conductive adhesive; an inner slot is formed at the center of the ceramic lamp cap, and is provided with two wiring holes on the bottom; a silver foil is sintered on the bottom of the ceramic lamp cap; and a round groove is formed on the outer circumference on the bottom of the ceramic lamp cap. According to the invention, the heat generated by an LED (light emitting diode) lamp module can be transferred to the ceramic lamp cap through a ceramic substrate with good conductivity, and then effectively transferred to a lamp holder and wires through the screw metal casing so as to realize full dissipation through the above media, wherein the heat dissipation manner includes conduction, convection and radiation. Moreover, the heat generated by the LED lamp module is dissipated stage by stage so as to obviate high wire temperature. In comparison with the existing aluminum lamp shade, the screw lamp cap provided by the invention is low in cost and safe in use, and facilitates popularization and application of LED bulbs.

Description

The lamp screw base that is used to dispel the heat
Technical field
The present invention relates to the LED lighting technical field, relate in particular to a kind of lamp screw base that is beneficial to heat radiation.
Background technology
In recent years, LED was used widely in every field as new light sources.But LED can produce great amount of heat in luminescence process, distribute if heat is untimely, and the life-span that makes LED is sharply decayed.Common LED bulb lamp adopts the lampshade heat radiation of aluminium basically at present, not only cost an arm and a leg, and because there is potential safety hazard in charged lamp holder and aluminium shell close proximity in the use.
Summary of the invention
The objective of the invention is to heat dissipation problem, a kind of lamp screw base that is used to dispel the heat is provided to the LED bulb lamp.
The objective of the invention is to realize: a kind of lamp screw base that is used to dispel the heat through following technical scheme; It comprises metal spiral shell and the ceramic lamp base that spins within it; Fill heat-conducting glue in the slit between metal spiral shell and ceramic lamp base; The metal spiral shell is contacted with ceramic lamp base closely, be convenient to heat radiation; The centre of ceramic lamp base has an inner dead slot, and the bottom of inner dead slot has two through wires holes, and the bottom of ceramic lamp base scribbles silver foil, and the bottom excircle of ceramic lamp base also has a circular trough.
The invention has the beneficial effects as follows: adopt the present invention; The heat that LED lamp group produces absorbs and transmission through the good heat absorption capacity and the conductive performance of ceramic lamp base; Conduct heat effectively through the spiral metal shell again; Reject heat to lamp socket again and above the lead, fully dispel the heat through above medium, radiating mode comprises conduction, convection current and radiation.And because the heat that LED lamp group produces absorbs through the big pottery of specific heat capacity and transmits, through the classification radiating and cooling, the temperature of lead can be very not high.The present invention compares with existing aluminium lampshade, and cost reduces, and is safe in utilization, helps the popularization and the application of LED bulb lamp.

Fig. 5 is the cutaway view of ceramic lamp base in the lamp screw base;
Among the figure, metal spiral shell 1, ceramic lamp base 2, heat-conducting glue 3, inner dead slot 4, silver foil 5, through wires hole 6, circular trough 7.
The specific embodiment
Describe the present invention in detail according to accompanying drawing below, it is more obvious that the object of the invention and effect will become.
Shown in Fig. 1-3; The lamp screw base that is used to dispel the heat of the present invention comprises metal spiral shell 1 and the ceramic lamp base 2 that spins within it; Fill heat-conducting glue 3 in the slit between metal spiral shell 1 and ceramic lamp base 2, metal spiral shell 1 is contacted with ceramic lamp base 2 closely, be convenient to heat radiation.
Fig. 2 and Fig. 3 show the structure of metal spiral shell 1 and ceramic lamp base 2 respectively.
Shown in Figure 4 and 5, the centre of ceramic lamp base 2 has inner dead slot 4, and the bottom of inner dead slot 4 has two through wires holes 6, and the bottom sintering of ceramic lamp base 2 has silver foil 5, and the bottom excircle of ceramic lamp base 2 also has a circular trough 7.
The material of metal spiral shell 1 can be copper nickel plating, iron nickel plating, and heat radiation is convenient in aluminium nickel plating etc.The excircle of ceramic lamp base 2 has the external screw thread that the internal thread with metal spiral shell 1 is complementary, and can contact closely with metal spiral shell 1 after ceramic lamp base 2 screws in, and in the two slit, can fill heat-conducting glue 3, make its closely contact be convenient to dispel the heat.
There is dead slot 4 inside of ceramic lamp base 2 up to the bottom, so that settle the driving power of LED.Through wires hole 6 is used to pass the lead-in wire of LED.After the ceramic lamp base 2 bottom preliminary treatment, send ceramic post sintering stove sintering, make ceramic lamp base 2 bottoms have one deck silver foil 5 through molding, after being coated with photoresists, exposure, washing, the printing of silver slurry.Silver foil 5 is used for from now on lamp pearl, lamp group or the welding of lamp bar with LED.There is circular trough 7 outer ring, bottom of ceramic lamp base 2, is used for fixing the lampshade of plastics or glass.
Ceramic lamp base 2 structures that pottery burns till Fig. 3 through molding.Because pottery is a kind of good conductor of heat, be again the big material of specific heat capacity, pottery is as a kind of working material of novel heater element; Have the good electric insulating properties, high thermal conduction characteristic, anticorrosive and characteristic ultraviolet; The present invention is with the ceramic lamp base 2 of the sintering silver lamp holder as the LED lamp; Not only have good heat-transfer effect, and reduced production cost significantly, improved security performance.
