Wherein, larger than the diameter of this LED silk 1 millimeter to 2 millimeters of the diameter of this tubulose lampshade.

The beneficial effects of the utility model are: the situation being different from prior art, and the utility model provides a kind of light fixture, and it is electrically connected by multiple LED silk, and carry out encapsulating and being formed, and can extend LED lamp tube length thus.Its manufacturing process is simple, with low cost, and the length of fluorescent tube can flexible design as requested.

Accompanying drawing explanation

In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:

Fig. 1 simplifies structural representation according to the light fixture of the utility model one preferred embodiment;

Fig. 2 is the LED silk structural representation in the light fixture shown in Fig. 1;

Fig. 3 is the splicing ear partial enlarged drawing of LED silk in the light fixture shown in Fig. 1;

Fig. 4 is the light fixture schematic diagram according to another preferred embodiment of the utility model.

Detailed description of the invention

Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.

As shown in Figures 1 to 4, the utility model provides a kind of light fixture 10, and it comprises: tubulose lampshade 11, LED silk 12 and sealing silica gel 13.

Wherein tubulose lampshade 11 was drawn in advance before LED silk 12 is put into, and its material can be glass, plastics etc., and the length of lampshade 11 is slightly larger than the entire length of LED silk 12, preferably, and lampshade 11 length 3mm ~ 5mm larger than LED silk 12 length.Tubulose lampshade 11 diameter also should slightly larger than the diameter of LED silk 12, preferably, and lampshade 11 diameter 1mm ~ 2mm larger than LED silk 12 diameter.Be inserted in after in lampshade 11 at LED silk 12, at the two ends of LED silk 12, sealing silica gel 13 seals.Wherein as shown in Figure 1 and Figure 2, LED silk 12 described in the utility model comprises packaging silicon rubber 14 and multiple LED lamp bead 15, and wherein multiple LED lamp bead 15 is located in this packaging silicon rubber 14, and series connection forms LED silk 12.

In addition, this LED silk 12 also comprises splicing ear 16, and this splicing ear 16 is located at the two ends of LED lamp bead 15, and stretches out this sealing silica gel 13 outward.Undertaken being welded to connect by this splicing ear 16 between multiple LED silk 12 and form this light fixture 10.

As shown in Figure 4, be also provided with lamp holder 17 and pin 18 respectively at light fixture 10 two ends, lamp holder 17 and pin 18 are connected with external power supply (not shown) for light fixture 10, and its structure and material do not relate to inventive point place, repeat no more herein.

According to the actual demand to application luminaire, 3 ~ 4 LED silks can be welded to connect, for such as household reading lamp, indoor fluorescent tube etc.

In addition, the splicing ear 16 of LED silk 12 also can adopt hook, snap close etc.

Preferably, as shown in Figure 3, Fig. 3 is the splicing ear partial enlarged drawing of LED silk in light fixture described in the utility model.This splicing ear 16 comprises main part 161 and connecting portion 162, and wherein connecting portion 162 is in strip, is located in packaging silicon rubber 14, and main part 161 is in circular, and stretches out the two ends of packaging silicon rubber 14 in LED silk 12 outward.

In order to avoid occurring when LED silk 12 connects loosening, situation fastening not, preferably, the utility model is provided with linking springs 19 at the main part 161 of splicing ear 16.As shown in Figure 3, this linking springs 19 for being electrically connected the main part 161 of two LED silks 12 of next-door neighbour, due to the characteristic of linking springs 19 self, when light fixture 10 is installed, not only can play the effect connecting LED silk 12, also can solve the situation that it is loosening, not clamping.
