Detailed description of the invention
As shown in Fig. 1 and 2, be profile of the present utility model and exploded view.The utility model light emitting diode bulb mainly includes lamp socket 1, lampshade 2, and heat-conductive assembly 3, this lamp socket 1 supplies the lampshade 2 of glass to connect together with it, form the type body of a bulb by this, this lamp socket 1 is adopted vertical and is installed with several light-emitting diode light bar 11 place, light direction of illumination changes 360 degree of comprehensive projections into by one direction, industry is also referred to as 4 π bright dippings, bulb brightness can effectively be promoted, but along with the number of light-emitting diode light bar 11 is more, radiating effect in bulb requires also higher, the utility model is installed with this heat-conductive assembly 3 in this lamp socket 1 place, brightness and heat radiation is allowed all can effectively to promote by this.
This lamp socket 1 comprises by least one light-emitting diode light bar 11, base 12, control circuit unit 13 and lamp holder 14, and this base 12 includes a separable base cover 121 further.This light-emitting diode light bar 11 inside adopts LED crystal particle, and can provide the comprehensive ray cast of 360 degree, industry is also referred to as 4 π bright dippings.This light-emitting diode light bar 11 one end has metal electrode 111.This base cover 121 has at least one jack 122 and fixing hole 123.This jack 122 number is to should the number of light-emitting diode light bar 11, and be installed on this for lamp bar, this metal electrode 111 can extend to below this base cover 121, is electrically connected with this control circuit unit 13.This control circuit unit 13 has interlock circuit and electronic building brick (only illustrating with square in figure), and primary responsibility accepts power supply and drives this light-emitting diode light bar 11 shinny.This control circuit unit 13 is installed on the space formed with this lamp holder 14 in this lamp socket 12.In the shape of a spiral, external form and size are the standard specifications meeting current light fixture to the metal outer wall of this lamp holder 14.This control circuit unit 12 object is: by power voltage step down and rectification during use, and through plain conductor 131,132 electrode corresponding with this lamp holder 14 as electric connection, and this part is similar to conventional therefore no longer encyclopaedize.This base 12 is incorporated into this lamp holder 14 top, and this base 12 outer wall separately has the engagement groove 120 of an annular in the present embodiment, plants wherein with the openend 21 for this lampshade 2.
This lampshade 2 is made up of clear glass, and bottom has an openend 21.This lampshade 2 type body is as ball cone, and this openend 21 outer wall dimension is smaller, is formed as neck shape structure.During assembling, this lampshade 2 is placed in the engagement groove 120 of this base 12, and then closed by this lampshade 2.In the process that this lampshade 2 is closed in addition, what one is particularly good at, prior to injecting helium in inner space, increases radiating effect, to extend the service life of bulb.
This heat-conductive assembly 3 is a metal heat carrier, and the present embodiment is an aluminum metal.This heat-conductive assembly 3 is the pipe fitting of a hollow, therefore there is the heat conduction road 31 of a longitudinal direction, main body is divided into the first half 32 and Lower Half 33 liang of parts, during assembling, this heat-conductive assembly 3 is these fixing holes 123 of planting, be installed on this base cover 121 place, this first half 32 is positioned in this base cover 121, this lampshade 2, and Lower Half 33 extends in this lamp socket 1, and is combined with this lamp holder 14 through heat-conducting glue 15.Polishing is bestowed on this first half 32 surface, has reflecting surface effect, and local outer wall shape is cone, and shape is in from top to bottom cumulative shape, and this shape contributes to the light of light-emitting diode light bar 11 to external reflectance.This cone 321 surface is in flank, and this object, for increasing surface area, increases the contact area with hot-air in bulb when bulb is shinny, heat, through the light fixture of this heat-conductive assembly 3, lamp holder 14 to bulb mounting, allows thermal energy conduction go out, reaches the object of heat radiation.The radial direction of this heat-conductive assembly 3 has at least one hole 34 and communicates with inner heat conduction road 31 in addition, and the position in this hole 34 is lower than the cone position of this first half 32, and object increases hot gas convection current in bulb, contributes to heat radiation.Or be installed in this base cover 121 at this heat-conductive assembly 3, the wherein hole 34 of this heat-conductive assembly 3 radial direction setting, wherein at least one is positioned at the position on this base cover 121 and heat-conductive assembly 3 joint, or wherein at least one is positioned at the position under this base cover 121 and heat-conductive assembly 3 joint.
In addition when assembling, the openend 21 of this lampshade 2 is socketed in the engagement groove 120 of this base 12, and in order to reach good sealing, both seam crossings can be adopted viscose and fix.But in order to consider the convenience of assembling, the utility model separately includes a seal mouth ring 4, and seal mouth ring 4 is made for quality of rubber materials.When assembling, this seal mouth ring 4 can be placed in this engagement groove 120 in advance, this lampshade 2 is installed on this more afterwards, this seal mouth ring 4 just can be close to this lampshade 2 openend 21 and this engagement groove 121 inwall, the effect reaching excellent sealing and prevent internal gas from leaking, the action omitting viscose like this, allows when assembling more convenient.
The utility model light emitting diode bulb in an assembling process, the light-emitting diode light bar 11 of this lamp socket 1, base 12, control circuit unit 13 and lamp holder 14, sequentially fit together, and complete the electric connection of associated components, still have in this process and a littlely carry out weld job, but this is the kenel of general bulb basic operation, in process, this heat-conductive assembly 3 is also installed on base cover 121 place of this base 12 in addition, finally again this lampshade 2 is combined with this base 12, namely complete the assembling of bulb.
Because bulb of the present utility model is owing to having this heat-conductive assembly 3, when light-emitting diode light bar 11 is shinny, the cone energy reflection ray of the first half 32 of heat-conductive assembly 3, increases brightness and has the effect of diffused light source, makes the light type that projects even more ideal.The heat conduction road 31 of this heat-conductive assembly 3 longitudinal direction and the hole 34 of transverse direction, can allow hot-air convection in lampshade 2, allow the hot-air close to light-emitting diode light bar 11 flow to this lampshade 2 internal face of glass system, to reach the object of heat radiation through lampshade 2 through heat trnasfer with the cold air outside lampshade 2.This heat-conductive assembly 3 also expands contact area heat absorption through the first half 32 because of flank in addition, and heat, again through the light fixture of this heat-conductive assembly 3, lamp holder 14, bulb mounting, allows thermal energy conduction go out, reaches the object of heat radiation.Design of the present utility model like this, when light-emitting diode light bar 11 number increases, still can have good radiating effect, in order to the exploitation of high-power lamp bulb, meets the application important document of patent.
As described above, be only preferred embodiment of the present utility model, is not used for limiting the scope of the utility model embodiment.Namely all equalizations done according to the utility model claim change and modify, and are all the scope of the claims of the present utility model and contain.
