The following specific embodiment further specifies the present invention in connection with above-mentioned accompanying drawing.
The specific embodiment
See also Fig. 1, the present invention than better embodiment in, a panel guiding device comprises that a panel 10, is installed on light guide structure 30 and the light source 50 on the described panel 10.In the present embodiment, described light source 50 is light emitting diode.
Described panel 10 comprises top board 13 and two side plates 15 that extend to form from the both sides of described header board 11 that a header board 11, extends to form along the top edge of described header board 11.Described side plate 15 vertical described top boards 13.Described header board 11 is curved.Described header board 11 is provided with an elongated opening 111.
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 light guide section 33 is cuboid, and described light guide section 33 comprises the end face 332 of one first bottom surface 331, parallel described first bottom surface 331, two the first end faces 333, the second end face 335 of vertical described first bottom surface 331 and the 3rd end faces 337 of vertical described first bottom surface 331.Described the 3rd end face 337 parallel described the second end faces 335.Described end face 332 is connected between described the second end face 335 and described the 3rd end face 337, described transmittance section 31 comprises the first side 312, exposure 314 and two second sides 316 that are parallel to each other that connect between described the first side 312 and described the second bottom surface 311 of one second bottom surface 311, parallel described second bottom surface 311, and described exposure 314 is used for being contained in described elongated opening 111.In the present embodiment, described exposure 314 parallel described the second end faces 335.The first bottom surface 331 of described light guide section 33 and the second bottom surface 311 of described transmittance section 31 are in the same plane.316 vertical described the second bottom surfaces 311, described the second side.Described the second side 316 is in the same plane with described the first end face 333.Described the first bottom surface 331 vertical described header boards 11.Described transmittance section 31 comprises that one is positioned at the end 315 of the first end face 333 1 sides of described light guide section 33.The cross section of parallel described first end face 333 of described light guide structure 30 is L-shaped.
