Following detailed description of the invention will further illustrate the present invention in conjunction with above-mentioned accompanying drawing.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail.
Refer to Fig. 1 and Fig. 2, a kind of light-emitting diode lamp tube 100 that embodiment of the present invention provides comprises the lampshade 10 of a hollow tubular, the lamp holder 20 being arranged at these lampshade 10 two ends, multiple LED sources 40 of being arranged at the multiple light guide plates 30 in lampshade 10 and being arranged on light guide plate 30 end face.
Described lampshade 10 is made up of the good material of light transmission, such as glass, Merlon etc.This lampshade 10 inner surface can apply diffusion particle, make it have scattering function, thus the soft degree of light can be increased.
Described lamp holder 20 is traditional lamp head of fluorescent lamp, and it is roughly cylindric in one.The end face away from lampshade 10 of this lamp holder 20 is extended with two for the plug 21 with external receptacle grafting.The external diameter of one end of the close lampshade 10 of this lamp holder 20 is roughly the same with the internal diameter of lampshade 10, and the end of lampshade 10 can be sheathedly fixed on lamp holder 20 thus.Described lamp holder 20 inside comprises circuit board 22 and multiple fixed head 23.The axis of the vertical lamp holder 20 of described circuit board 22 is arranged, and described multiple fixed head 23 is extended vertically upward by the surface towards lampshade 10 side of circuit board 22.Multiple fixed head 23 encloses a column structure around the central shaft of lamp holder 20.In the present embodiment, the quantity of described fixed head 23 is 3, and 3 fixed heads 23 enclose a triangular prism structure.
Please then consult Fig. 3 and Fig. 4, each light guide plate 30 is an elongated rectangular plate-like structure.Multiple light guide plate 30 is contained in lampshade 10 and central axis direction along lampshade 10 extends.Multiple light guide plate 30 encloses a column structure around the central shaft of lampshade 10, and wherein the inner surface of each light guide plate 30 is just to the central shaft of lampshade 10, and the inner surface of the corresponding lampshade 10 of outer surface is also respectively towards different directions.The quantity of light guide plate 30 is identical with the quantity of the fixed head 23 of lamp holder 20, and the inner surface at multiple light guide plate 30 two ends is sticked one by one respectively and is fixed on corresponding fixed head 23.In the present embodiment, the quantity of described light guide plate 30 is 3, and 3 light guide plates 30 are angularly arranged, and enclose a triangular prism structure.
The inner surface of each light guide plate 30 offers multiple bright dipping site 31 respectively, and these bright dipping sites 31 can be destroyed the total reflection of light and play dispersion effect to light, realize even bright dipping thus.In the present embodiment, multiple bright dipping site 31 is the arcuation groove structure of evenly arrangement, and the size of these groove structures between several micron to a hundreds of micron, thus can increase the dispersion effect of light.In other embodiments, this bright dipping site 31 also can be the bump structure of micron-scale size.
Be understandable that, multiple bright dipping site 31 also can be non-homogeneous arrangement, namely, can according to the bright dipping demand of reality, the arrangement density of bright dipping site 31 is reduced to two ends gradually from the centre of light guide plate 30, or the arrangement density of bright dipping site 31 is reduced to the other end gradually from one end of light guide plate 30.
In addition, will also be appreciated that described multiple bright dipping site 31 also can be formed on the outer surface of light guide plate 30.
The inner surface of each light guide plate 30 has also been sticked respectively reflecting piece 50, and this reflecting piece 50 can reflect light, realizes the one side bright dipping of light guide plate 30 thus, to promote the utilization ratio of light, makes more light from the outer surface outgoing of light guide plate 30.
Refer to Fig. 5, be understandable that, the inner surface of described light guide plate 30 also can not arrange reflecting piece 50, the inner surface of light guide plate 30 and outer surface all can bright dippings thus.
Described multiple LED source 40 respectively one_to_one corresponding is sticked on one of them end face of each light guide plate 30.And when assembling, LED source 40 realizes being electrically connected with plug 21 by the circuit board 22 of lamp holder 20.
Described light-emitting diode lamp tube 100 operationally, inject in light guide plate 30 by the end face of light guide plate 30 by the light that LED source 40 sends, and then scattered outside light guide plate 30 by the bright dipping site 31 of light guide plate 30, thus realize even bright dipping.And due to light guide plate 30 equiangularly mode arrange, the exiting surface of each light guide plate 30 is respectively towards different directions, and light-emitting diode lamp tube 100 like this spatially can realize evenly going out Light distribation close to full angle.In addition, because the inner surface of lampshade 10 is also coated with diffusion particle, therefore, it is possible to increase the diffusion of light and soft degree further.
Refer to Fig. 6, be understandable that, the opposite end surface of described light guide plate 30 can arrange LED source 40, the bright dipping of light guide plate 30 so can be made more even.
In light-emitting diode lamp tube 100 of the present invention, multiple light guide plate 30 encloses a column structure, LED source 40 is attached on the end face of light guide plate 30 respectively, the light sent by LED source 40 is scattered by the bright dipping site 31 of light guide plate 30 inner surface or outer surface, thus makes light-emitting diode lamp tube 100 spatially can realize evenly going out Light distribation close to full angle.
Be understandable that, for the person of ordinary skill of the art, the change and distortion that other various picture answers can be made by technical conceive according to the present invention, and all these change the protection domain that all should belong to the claims in the present invention with distortion.
