Detailed description of the invention
Being described in further detail the utility model below in conjunction with the drawings and specific embodiments, is not that practical range of the present utility model is confined to this.
As shown in Fig. 1 to body Fig. 4, a kind of light guide plate stage described in the present embodiment, include the stage bracket a in matts shape, the grid of stage bracket a is provided with light guide plate; The edge of described stage bracket a is provided with LED lamp bar B;
Light guide plate includes light conducting plate body 1, and described light conducting plate body 1 side is provided with incidence surface 2, and described incidence surface 2 is zigzag; The crown angle of described each sawtooth is 10 degree to 50 degree; Described light conducting plate body 1 end face is distributed with and a plurality ofly hits spot hole 3, described each spot hole 3 of hitting includes the curved single order depression 31 of inwall, described single order depression 31 is extended with the curved second order depression 32 of inwall downwards, described second order depression 32 is extended with three curved rank depressions 33 of inwall downwards, and described three rank depressions 33 are extended with in hemispheric quadravalence depression 34 downwards; The top end opening place diameter of described single order depression 31 is greater than second order and caves in 32 top end opening place diameters; Described second order cave in 32 bottom end opening place diameters be greater than three rank cave in 33 top end opening places depression; The hemisphere face diameter of described quadravalence depression 34 and three rank cave in 33 bottom end opening place diameter identical.Described LED lamp bar B aims at incidence surface 2.A kind of light guide plate stage described in the present embodiment is by above-mentioned setting, and LED lamp bar B aims at incidence surface 2; Realize the uniformly light-emitting of light guide plate, so only need light bar to realize stage illumination, lighting, realize power saving, and light-out effect is even, promote stage effect.Described incidence surface 2 is zigzag; The crown angle of described each sawtooth preferably 30 degree, can effectively make laser make a light guide plate without hot spot and bright shadow phenomenon, successful by this incidence surface 2.The setting of single order depression 31 to quadravalence depression 34, finds that its even light rate is best, not easily occurs hot spot and bright shadow from experiment, evenly luminous.
A kind of light guide plate stage described in the present embodiment, the bottom surface of described light conducting plate body 1 is provided with a plurality of conical indentation 4; The cone angle of described each conical indentation 4 is less than 50 degree.A kind of light guide plate stage described in the present embodiment, the cone angle of described each conical indentation 4 is 35 degree.A kind of light guide plate stage described in the present embodiment, the top end opening place diameter of described single order depression 31 is 0.1mm-0.2mm.A kind of light guide plate stage described in the present embodiment, the described second order 32 bottom end opening place diameters that cave in are 0.05mm-0.1mm.A kind of light guide plate stage described in the present embodiment, the bottom end opening place diameter of described three rank depressions 33 is 0.01mm-0.05mm; This numerical value, find when testing, its even light effect is best, and luminescence is the most even.
A kind of light guide plate stage described in the present embodiment, the bottom surface of described light conducting plate body 1 is covered with one deck photic zone 5; The bottom surface of described photic zone 5 is provided with a plurality of end to end curved light inlet projection 6; Bottom light source can effectively be caught by this structure, and bottom light source and side light source are not affected mutually, and light-out effect is good.
