In order to describe structure of the present utility model and characteristics in detail, existing following preferred embodiment of act and conjunction with figs. are described as follows.

As shown in Figure 1 and Figure 2, be a kind of led lamp assembly 100 that the utility model one preferred embodiment is provided, it consists predominantly of a lamp socket 10 and a light-emitting substrate 20, wherein:

Lamp socket 10, plastic material by insulation is made into integration, as PC (poly-carbon ester resin), PE (polyethylene) or PP (polypropylene) ... Deng, lamp socket in the present embodiment adopts has good insulation performance, insulating characteristics, and the PC (poly-carbon ester resin) with high grade of transparency is made into integration.Lamp socket 10 has a light shield body 11, a conjunction 12 and a base 13.Light shield body 11 has high light transmittance, generally is an oval moulding, and its inside is formed with an opening 141 saturating dummy section 14 down.Conjunction 12, be two built-in bricks, be formed at respectively on the light shield body 11 2 relative outer side edges, two built-in bricks have an attachment-receiving member 121 and a limiting section 122 respectively, each attachment-receiving member 121 is convexly set in respectively on the two relative outer side edges of light shield body 11, and be positioned on the outside, stage casing of light shield body 11, one predetermined distance arranged apart from its root edge.Each limiting section 122 is convexly set on the two relative outer side edges of light shield body 11, and each limiting section 122 forms from the side lower edge extension downwards of attachment-receiving member 121 respectively.Base 13, generally be a cylinder, the one end is connected with the root edge of light shield body 11, the inside of base 13 is formed with an accommodation space 16 relative with the transmission region 14 of light shield body 11, two opposite sides of accommodation space 16 also extend respectively laterally, form a conjugate foramen 17 that connects with base top surface respectively, and wherein a conjugate foramen 17 extends to perforation more laterally, make be formed with on base 13 1 sides one be communicated to accommodation space 16 insert hole 18.

Light-emitting substrate 20 is one to be laid with the printed circuit board (PCB) (PCB) of predetermined electronic component, has an electric substrate 21, two junctions 22, a resistance 23 and two light emitting diodes (LED) unit 24.On the end face of electric substrate 21, be laid with the wiring (not shown) that is predetermined form.Two junctions 22 are made of tin cream respectively, can certainly be other materials that can electrically conduct, and each junction 22 is arranged at the relative proximity two side edge places of electric substrate 21 end faces respectively, and electrically conduct with wiring.Two light emitting diodes 24 (can be known LED illuminator, its detailed structure appearance is not given unnecessary details) are arranged on the end face of electric substrate 21, and electrically conduct with wiring.Resistance 23 is used for adjusting the voltage and the electric current of circuit, can be general traditional plug-in type resistance or chip-shaped resistance, is arranged at the position in rough the putting on electric substrate 21 end faces, and electrically conducts with wiring.

More than be the constitutive requirements of led lamp assembly 100 provided by the utility model, then again its assembling mode and advantage thereof be described below:

When lamp socket 10 is made in integrally formed mode, and after light-emitting substrate 20 assembling finished, just a side of light-emitting substrate 20 directly can be penetrated by the hole 18 of inserting of lamp socket 10, be arranged in accommodation space 16 (as shown in Figure 2), thus, each junction 22 that is arranged in light-emitting substrate 20 end faces two sides just can outer be exposed at each conjugate foramen 17, and the base 10 that makes light-emitting substrate 20 can be engaged 17 belows, hole supports fixing, and each light emitting diode 24 is the opening 141 of subtend in lamp socket 11, make and do the time spent (when being luminous), can will penetrate out in the saturating dummy section 14 of its light source by light shield body 11 when light emitting diode 24.

Above-mentioned being in the utility model LED light lamp seat assembly 100, the assembling mode that combines of lamp socket 10 and light-emitting substrate 20, then the mode of again a utility model led lamp assembly 100 and a control circuit board 30 being assembled is described below:

At first, control circuit board 30 is formed with the perforation 31 (as shown in Figure 3) that is predetermined form thereon, and on perforation 31 side, form contact zone 32 (as shown in Figure 4) with circuit communication, the perforation 31 that the light shield body 11 of the utility model lamp socket 10 and conjunction 12 are passed control circuit board 30, make the apical margin and the control circuit board 30 of base 20 inconsistent, then again led lamp assembly 100 is rotated, the attachment-receiving member 121 of conjunction 12 is connected on the control circuit board 30, makes that control circuit board 30 can be by clamping between the apical margin of attachment-receiving member 121 and base 30.When rotating led lamp assembly 100 to preposition, just can lean by the limiting section 122 of conjunction 12 and the edge of perforation 31, make led lamp assembly 100 to be fixed on the preposition.That is, this moment, the junction 22 of light-emitting substrate 20 can contact with the contact zone 32 of control circuit board, and controlled circuit board 30 is controlled with the conducting of contact zone 32 to make light emitting diode 24 can pass through junction 22.

In sum, the utility model becomes a light-emitting substrate 20 by resistance 23, junction 22 and light emitting diode 24 are incorporated on the electric substrate 21, and insert hole 18 for what light-emitting substrate 20 penetrated by on transparent lamp socket 10, directly offering one, make light-emitting substrate 20 only need an insert action just can finish assembling with lamp socket 10, utilize simple structure to finish easy assembly program.

In addition,, can on junction 22, increase a tin ball or wire and increase height, guarantee the electrical communication of 30 of junction 22 and control circuit boards for avoiding the height deficiency of junction (being tin cream) 22 when being coated with.

Secondly, present embodiment is that resistance 23 and light emitting diode 24 are arranged on the same end face (being end face) of electric substrate 21, also resistance 23 can be arranged on the bottom surface of electric substrate 21 certainly, to improve heat radiation function.
