The specific embodiment

Relevant detailed description of the present utility model and technology contents will cooperate graphic being described as follows, yet appended graphic only purposes as an illustration is not to be used to limit to the utility model.

The utility model discloses a kind of sealing lid of led lamp, please refer to Fig. 1 to shown in Figure 6, light fixture 1 comprises a shell block 100, a circuit board 200, at least one light emitting diode 300, line cover 400, one conductor wire 500, a fluid sealant 600, reaches sealing lid 700.

Shell block 100 is hollow cylindrical (as Fig. 1), but be not shaped as restriction with this, shell block 100 has a cavity volume 110 and connection cavity volume 110 and is formed on an opening 120 of cavity volume 110 ends, opening 120 is for being opened in an end of shell block 100, and the other end of shell block 100 offers a perforation 130 that is communicated with cavity volume again.

Circuit board 200 is embedded at (as Fig. 3) in the cavity volume 110, corresponding openings 120 configurations of light emitting diode 300 and be fixed on the circuit board 200 and electrically connect the electronic loop of circuit board 200, then the light that sends of light emitting diode 300 can expose to the external world from opening 120, and light emitting diode 300 comprises a pin 310 that is fixed on the circuit board 200 and electrically connects the electronic loop of circuit board 200 again.

Line cover 400 is hollow circle shell-like, but is not shaped as restriction with this, and line cover 400 is made by the material with telescopic resilience, rubber bodies for example, but be not restriction with this material, line cover 400 is connected in the perforation 130 again.

Conductor wire 500 is connected in the line cover 400, and conductor wire 500 1 ends are placed in the cavity volume 110 and electrically connect the electronic loop of circuit board 200, conductor wire 500 comprises a terminal 510, and promptly terminal 510 is placed in the cavity volume 110 and electrically connects the electronic loop of circuit board 200.

Conductor wire 500 other ends then are electrically connected to external power source, when conductor wire 500 is connected in the line cover 400, can strut line cover 400 a little again, make conductor wire 500 and line overlap 400 for fitting tightly, and make line cover 400 and shell block 100 for fitting tightly, make connection comparatively firm.

Fluid sealant 600 pours into and fills in cavity volume 110 (as Fig. 3 and Fig. 4) from opening 120; fluid sealant 600 is made for the insulation material; it can be epoxy resin or Silicon dioxide, hydrate; but be not restriction with these a little materials; the electronic loop that fluid sealant 600 can covering boards 200, pin 310, and terminal 510 are not encroached on by aqueous vapor or external substance to protect these a little assemblies again.

Sealing is covered 700 involution openings 120 and is sealed fluid sealant 600 up for safekeeping and offer a through hole 710 (as Fig. 5) that supplies light emitting diode 300 cross-under, make fluid sealant 600 be held being stored in the cavity volume 110 and can not flow out, the top of light emitting diode 300 is arranged in through hole 710, and sealing lid 700 is exposed at the top of light emitting diode 300, thereby the light that sends still can expose to the external world not can by sealing cover 700 block (as Fig. 6).

In addition, sealing lid 700 forms an anti-overflow bulge loop 720 (as Fig. 2 and Fig. 5) that extends towards circuit board 200 directions in through hole 710 peripheral regions, and the outer peripheral edges place of sealing lid 700 forms an anti-overflow barricade 730 that extends towards circuit board 200 directions, then when sealing is covered 700 involution openings 120 and is sealed fluid sealant 600 up for safekeeping, anti-overflow bulge loop 720 makes the area between sealing lid 700 and the light emitting diode 300 increase, anti-overflow barricade 730 makes the area between shell block 100 and the sealing lid 700 increase, so that fluid sealant 600 overflows through hole 710 and overflows the path lengthening of 120 processes of opening, promptly cause frictional resistance to increase, thereby avoid fluid sealant 600 to overflow from through hole 710 and opening 120.

If fluid sealant 600 overflows from through hole 710 or opening 120, can be stained with glutinous to light emitting diode 300, and the light that makes light emitting diode 300 send is blocked, thereby influence the exposure intensity of light emitting diode 300, again if fluid sealant 600 overflows, can be stained with glutinously, so all can cause bad influence, can stop and prevent that fluid sealant 600 from overflowing so 700 anti-overflow bulge loop 720 and anti-overflow barricade 730 are built in sealing to other external module.

Again, enclose between anti-overflow bulge loop 720 and the anti-overflow barricade 730 to be formed with and be communicated with one of cavity volume 110 and hold glue space 800, holding glue space 800 can be ccontaining for fluid sealant 600, makes fluid sealant 600 more be difficult for overflowing.

Please refer to shown in Figure 7, sealing lid 700 forms a burr 740 in the inner peripheral place of through hole 710 and the inner peripheral place of anti-overflow bulge loop 720, burr 740 is shape, ring-type or netted in the shape of a spiral, but be not shaped as restriction with this, its role is to increase the area that contacts with fluid sealant 600, the frictional resistance that makes fluid sealant 600 overflow is bigger, and promptly fluid sealant 600 more is difficult to overflow.

Certainly; the utility model also can have other various embodiments; under the situation that does not deviate from the utility model spirit and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
