Detailed description of the invention
For further illustrating each embodiment, the utility model provides accompanying drawing.These accompanying drawings are a part for the utility model disclosure, and it is mainly in order to illustrate embodiment, and the associated description of description can be coordinated to explain the operation principles of embodiment.Coordinate with reference to these contents, those of ordinary skill in the art will be understood that other possible embodiments and advantage of the present utility model.Assembly in figure not drawn on scale, and similar element numbers is commonly used to assembly like representation class.
Now with detailed description of the invention, the utility model is further illustrated by reference to the accompanying drawings.
Consult shown in Fig. 1 to Fig. 8, the LED lamp tube of the preferred a kind of anti-bending distortion of an embodiment of the utility model, it comprises lampshade pipe 2, light source board 3, heat sink 4, lamp holder 1 and driving power 5.Wherein, lampshade pipe 2 inside is provided with support 21, and heat sink 4 is fixedly installed on the stent 21.Consult shown in Fig. 5, the heat sink 4 of this embodiment has multiple fin, the upper end profile of fin is the cambered surface fitting in lampshade pipe 2 inner tubal wall, heat sink 4 is also provided with snap fit, light source board 3 is positioned in snap fit, light source board 3 is connected with heat sink 4, and the two ends of heat sink 4 are respectively equipped with a screwed hole.The length of heat sink 4 is greater than the length of lampshade pipe 2, and the two ends of lampshade pipe 2 all have heat sink 4 to expose; Two lamp holders 1 are fixed on the exposed parts of heat sink 4, and two lamp holders 1 are respectively by the closed at both ends of lampshade pipe 2.
Consult shown in Fig. 2 and Fig. 4, the lampshade pipe 2 of this embodiment is two-colour tube, and lampshade pipe 2 is made up of shading light part 22 and 23 two, light transmission part part.The lampshade pipe 2 of this embodiment is overall plastic two-colour tube structure, adopt two-shot molding process, the shading light part 22 of lampshade pipe 2 and light transmission part 23 are injection molded into different colors, and shading light part 22 adopts extinction material, and the ght transmission being irradiated to lampshade pipe 2 shading light part 22 is not gone out.Two-colour tube shading light part 22 and light transmission part 23 classifying rationally, light transmission part 23 is greater than 2/3 of lampshade pipe 2, reaches larger illumination effect.Meanwhile, the shading light part 22 of lampshade pipe 2 adopts extinction material, effectively can avoid dark space, and the bright dipping affecting LED lamp tube is attractive in appearance.
It should be noted that, the two-colour tube of this embodiment adopts two-shot molding process, the ratio of its shading light part 22 and light transmission part 23 can need adjustment according to user, and the shading light part 22 of this embodiment is 1:2 with the ratio of light transmission part 23, also can be other ratios such as 1:3.On lampshade pipe 2, the boundary of shading light part 22 and light transmission part 23 is clear, and the light type irradiated is attractive in appearance.
Again consulting shown in Fig. 7, is the side view of lampshade pipe 2.Lampshade pipe 2 is provided with support 21 in the junction of shading light part 22 and light transmission part 23, the region that this support 21 and shading light part 22 are formed is for placing heat sink 4, the upper end profile of the fin of heat sink 4 is the cambered surfaces fitting in lampshade pipe 2 inner tubal wall, thus contacts with the shading light part 22 of lampshade pipe 2 and support.Heat sink 4, except playing except thermolysis, also plays the effect of the intensity strengthening whole LED lamp tube.Consult shown in Fig. 7, be the side view of this embodiment lamp holder 1, in lamp holder 1, be also provided with support 12, for fixing the exposed parts of heat sink 4 relative to lampshade pipe 2.Consult shown in Fig. 6, lamp holder 1 is provided with two through holes, and two stitch 11 are stretched out by through hole, in addition in order to fixing lamp holder 1 and heat sink 4, lamp holder is also provided with a through hole closed with the corresponding threaded holes of heat sink 4, lamp holder 1 is fixedly connected with heat sink 4 by screw.
The driving power 5 of this embodiment can be arranged on wherein in any one lamp holder 1, and driving power 5 is electrically connected with the stitch 11 on light source board 3 and lamp holder 1 residing for it.Those skilled in the art is known, and the position of driving power 5 is not limited to lamp holder 1, also can optional position in or beyond lampshade pipe 2.
Consult the profile that Figure 8 shows that this embodiment, when assembling LED lamp tube, because heat sink 4 is long, therefore having certain distance between lamp holder 1 and lampshade pipe 2, not contacting completely.
When installing this embodiment, one end of this embodiment loads in lamp bracket, and the other end, by the distance between compression lamp holder 1 and lampshade pipe 2, makes the other end of this embodiment put into lamp bracket.The LED lamp tube of prior art, its lamp holder 1 fixes seamless cooperation with lampshade pipe 2, when mounted LED lamp pipe, compression lampshade pipe 2 may be needed LED lamp tube could to be put into lamp bracket, cause the flexural deformation of LED lamp tube.This embodiment when mounted, owing to having certain distance between lamp holder 1 and lampshade pipe 2, avoids stress between lampshade pipe 2 and lamp holder 1 to cause lampshade pipe 2 flexural deformation, thus ensures the deformability that LED lamp tube is less.During installation, only need compress the distance between lamp holder 1 and lampshade pipe 2, and lampshade pipe 2 can not flexural deformation, can realize the installation of this embodiment.
It should be noted that, because heat sink 4 is fixedly connected with lamp holder 1, therefore, when compressing the distance between lamp holder 1 and lampshade pipe 2, the flexural deformation that heat sink 4 is small can be caused.Because heat sink 4 is metal material, as aluminium base, have certain elastic deformation, small deformation can recover voluntarily.
Lamp holder 1 and lampshade pipe 2 are combined with anti-rotation and locate, and namely heat sink 4 is fixed in lampshade pipe 2 and lamp holder 1, avoids lamp holder 1 to coordinate rear rotation with lampshade pipe 2, and positioning lamp cap 1 and the screwed hole of heat sink 4, avoid manually going adjustment to aim at, improving production efficiency simultaneously.Consult shown in Fig. 6, lamp holder 1 adopts a screw to fix, and is better than mode market plane adopting two screws, promotes the efficiency of assembling of LED lamp tube.
Although specifically show in conjunction with preferred embodiment and describe the utility model; but those skilled in the art should be understood that; not departing from the spirit and scope of the present utility model that appended claims limits; can make a variety of changes the utility model in the form and details, be protection domain of the present utility model.
