Following embodiment further specifies the present invention in connection with above-mentioned accompanying drawing.
Embodiment
See also Fig. 1, the present invention than preferred embodiments in, a computer panel light conductive device comprises that a panel 10, is installed on light guide structure 30 and two light sources 50 on the described panel 10.
Described panel 10 comprises a header board 11.Described header board 11 comprises the depressed part 113 that a plate body 111 and is recessed to form from described plate body 111.Described depressed part 113 comprises a bottom 1131, described bottom 1131 parallel described plate bodys 111.Described panel 10 also comprises top board 13 and two side plates 15 that directly extend to form from the two sides of described plate body 111 marginal lappet that vertically extend to form along a coboundary of described plate body 111.Described side plate 15 vertical described top boards 13.Described depressed part 113 is provided with a elongated opening 1133 between described bottom 1131 and described plate body 111.
See also Fig. 2 and Fig. 3, described light guide structure 30 comprises a transmittance section 31 and a light guide section 33 that extends to form from described transmittance section 31.Described transmittance section 31 is provided with an exposure 311, and in the present embodiment, described exposure 311 is a curved surface, and described transmittance section 31 is used for being contained in described elongated opening 1133 and makes described exposure 311 be exposed to the outside of described panel 10.Described transmittance section 31 comprises two ends 313 that are positioned at described light guide section 33 both sides.Described light guide section 33 is rectangular parallelepiped, and described light guide section 33 comprises the end face 334 of a bottom surface 332, a parallel described bottom surface 332 and the side 335 of two vertical described bottom surfaces 332.Described light guide section 33 caves inward from described bottom surface 332 and forms one first recess 331 and one second recess 333.Described the first recess 331 is provided with two first refractive faces 3311 that are parallel to each other and first joint face 3313 that connects between described two first refractive faces 3311.Described first refractive face 3311 vertical described the first joint faces 3313.Described the second recess 333 is provided with two the second planes of refraction 3331 that are parallel to each other and second joint face 3333 that connects between described two the second planes of refraction 3331.The in the same size of described the first recess 331 and described the second recess 333 also is symmetrically distributed in the both sides of described light guide section 33.
See also Fig. 4 and Fig. 5, during installation, the transmittance section 31 of described light guide structure 30 is contained in makes described exposure 311 be exposed to the outside of described panel 10 in the described elongated opening 1133, at this moment, two ends 313 of described transmittance section 31 are between described plate body 111 and described bottom 1131.Described two light sources 50 are installed on respectively on the described panel 10 relatively and near two sides 335 of described light guide section 33.In the present embodiment, described light source 50 is light emitting diode.So far, assembling is complete.
