[specific embodiment]
About aforementioned and other technology contents, characteristics and effect of the present invention, in the detailed description of the preferred embodiment of following cooperation Figure of description, can clearly appear.
First preferred embodiment of LED bulb assembly of the present invention; Like Fig. 1 and shown in Figure 2; Comprise extra quality plastic lamp holder 1, LED element 2 and transparent outer cover 3, wherein extra quality plastic lamp holder 1 more includes insulating base 11, earth electrode 12 and conductive electrode 13, and insulating base 11 is constituted with non-conductive and tool photic plastic material; And this definition insulating base 11 plastic material be first plastic cement; And insulating base 11 also has one and supplies loading end 111 that LED element 2 is provided with and one to supply the lateral surface of installing 112, for the purpose of explanation, at this lateral surface further divided into partes glabra 1121, bottom 1122 and external thread part 1123; External thread part 1123 then is to be formed between partes glabra 1121 and the bottom 1122, and can supply to be screw-coupled to the power supply position.
In this example; Earth electrode 12 and conductive electrode 13 are to be formed by second plastic cement, have electric conductivity for making second plastic cement, therefore wherein are doped with conductive materials; For example copper doped, alloy that nickel, tin, aluminium or its alloy constituted; And the ratio of see through mixing, can make earth electrode 12 and conductive electrode 13 have a predetermined resistance, make input voltage in conduction automatic step-down during through earth electrode 12 and conductive electrode 13.Conductive electrode 13 is to pass insulating base 11 and be provided with, and makes one end thereof 131 be exposed to loading end 111 places, and another end 132 then is to be exposed to insulating base 11 lateral surfaces 112 and to extend to bottom 1122; Earth electrode 12 has an end 121 that is exposed to loading end 111 equally; And its other end 122 is the lateral surfaces 112 that partly are exposed to insulating base 11; And cover on the part surface of external thread part 1123; By this, the lamp socket that this case provided can be compatible to present standard lamp socket fully, and the consumer need not change any use habit fully.
In this example, the production method of extra quality plastic lamp holder 1 is with first plastic cement and two materials of second plastic cement; Before and after flow in the mould and be shaped simultaneously; Make extra quality plastic lamp holder 1 after extra quality plastic lamp holder 1 is shaped, can LED element 2 be arranged on the loading end 111 with the mode injection molding of extra quality cascode; And earth electrode 12 and conductive electrode 13 connected respectively to the conducting end of LED element 2; Again transparent outer cover 3 is combined and be fixed in insulating base 11, make LED element 2 can be packaged in the transparent outer cover 3, further protect LED element 2.Certainly, for affiliated technical field has common knowledge the knowledgeable, more can be as shown in Figure 3, end 122 also can cover the surface of external thread part 1123 fully, to increase the contact area of earth electrode 12.
Second preferred embodiment of LED bulb assembly of the present invention is as shown in Figure 4, and in this example, second plastic cement is that example is interpreted as acrylonitrile-styrene-butadiene copolymer resin (ABS; Acrylonitrile Butadiene Styrene) material; Because ABS itself is easy to electroplate; So generation type of earth electrode 12 ' and conductive electrode 13 '; Be directly with second plastic layer 124 ', 134 ' as Seed Layer, plate the conductive layer 126 ', 136 ' of layer of metal material again with the mode of electroplating.Certainly; Also can see through various metal different impedance values makes up; Make conductive layer 126 ', 136 ' can have a predetermined resistance; Make input voltage see through when conductive layer 126 ', 136 ' transmits and to receive impedance influences and step-down, and downgrade voltage required when meeting the LED element drives.
As shown in Figure 5; This routine transparent outer cover 3 ' has more one group of holding firmware 31 '; And insulating base 11 ' locates more to be formed with one group of fastener 14 ' that supplies the holding firmware 31 ' of deduction transparent outer cover 3 ' at corresponding loading end 111 ', when therefore carrying out last assembling operation, only need oppress transparent outer cover 3 ' and entangle insulating base 11 '; Can withhold holding firmware 31 ' after making fastener 14 ' oppressed, make that assembling operation can be more convenient and quick.
Yet, when the voltage of input is alternating current, can be as shown in Figure 6; This case the 3rd than embodiment, LED element 2 in this example " be with a plurality of LED crystal grain 21 " form, and by these LED crystal grain 21 " be combined into a rectification framework; and be formed with two guiding paths 5 respectively ", 6 "; when input voltage is positive voltage period, be positioned at path 5 " LED crystal grain 21 " can be luminous, be positioned at path 6 " LED crystal grain 21 " then can be not luminous; When input voltage is negative voltage period, then be to be positioned at path 6 " LED crystal grain 21 " can be luminous, and be positioned at path 5 " LED crystal grain 21 " can be not luminous; Therefore; See through the rectification framework that a plurality of LED elements are combined into,, can let the LED element on one of them path luminous at any time no matter be positive voltage period or negative voltage period; Do not need to be provided with in addition rectifier, can clasp the illumination total brightness of bulb assembly.
And the structure of the extra quality plastic lamp holder injection molding of this case more can be as shown in Figure 7 the 4th preferred embodiment; In this example, extra quality plastic lamp holder 1 " ' more comprise a lampshade 15 " ', and this routine lampshade 15 " ' be and extra quality plastic lamp holder 1 " ' penetrate simultaneously and be integrally formed structure; Especially at lampshade 15 " top layer 151 of light emission direction ' be positioned at " ' more can pass through surface treatment or plate the layer of metal layer; Make light to be reflected, therefore, what see through this example has a lampshade 15 " ' extra quality plastic lamp holder 1 " ' when throwing light on; Can make light source more concentrated, and promote the efficient of illumination; And bulb itself can reduce the cost of decoration design on the one hand promptly with lampshade, and the aspect can increase the elasticity of application in addition.
So a kind of LED bulb of this case is with extra quality plastic lamp holder and have the bulb assembly of this lamp socket, only need to have conduction and the non-conductive plastic cement extra quality plastic lamp holder that penetrates into simultaneously in the making; Let plastic lamp holder have conductive characteristic, be different from metal lamp holder production method in the past, make to make and go up become simpler; Help to promote make efficiency, also can reduce greatly, and when making plastic lamp holder, more can control and mix or the ratio mode of plated metal for the cost of making; The resistance value of adjustment conductive electrode and earth electrode; Promptly generally the chamber electricity that provides of Power Block drives the bulb assembly of this case, so need not to purchase in addition transformer, not only can increase profit; And the user also can more conveniently use, and reaches above-mentioned all purposes.
The above person of thought; Be merely preferred embodiment of the present invention; When not limiting the scope that the present invention implements with this, the simple equivalent of promptly being done according to claims scope of the present invention and description of the invention content generally changes and modifies, and all should still belong in the scope that patent of the present invention contains.
