Embodiment
Below will and describe clear explaination spirit of the present invention in detail with accompanying drawing, any those of ordinary skill in the art is after understanding preferred embodiment of the present invention, when can be by the disclosed technology of the present invention, change and modification, and do not break away from spirit of the present invention and scope.
With reference to Fig. 1, it is depicted as the schematic perspective view of an embodiment of the proving installation of adjustable light source spacing of the present invention.Base 100 has a load bearing seat 102, and load bearing seat 102 has a slide rail 122.Coulisse 104 is between base 100 and load bearing seat 102, and coulisse 104 has a plurality of chutes 106, and chute 106 is fan-shaped and is evenly distributed on the coulisse 104.Drive screw 108 all is arranged in the coulisse 104 with guide rod 110, and its two ends all are set up in separately the guide bar support 112, thus rotating drive screw rod 108 just can to drive coulisse 104 mobile on guide rod 110.Also be equipped with buffer stopper 114 between guide rod 110 and the guide bar support 112.Each take-up housing 116 can slide in chute 106 separately, but base 100 has a spacing cross bar 118, and it traverses in coulisse 104 tops, and take-up housing 116 is limited between load bearing seat 102 and the spacing cross bar 118.Light source driving circuit 120 is positioned at coulisse 104 tops, spacing cross bar 118 sides.
When coulisse 104 when the driving lower edge of drive screw 108 guide rod 110 moves, take-up housing 116 is because be subjected to the restriction of spacing cross bar 118 and load bearing seat 102, can't be along with coulisse 104 moves along guide rod 110, but because chute 106 is the oblique lines with slope, and take-up housing 116 is not restricted in the horizontal direction perpendicular to guide rod 110, so take-up housing 116 can move perpendicular to guide rod 110 along moving of guide rod 110 directions along with coulisse 104.So just realized not having the function that section is adjusted the take-up housing spacing.
With reference to Fig. 2, it is depicted as the wiring layout of an embodiment of take-up housing of the proving installation of adjustable light source spacing of the present invention.Printed circuit board (PCB) 202 is installed on the light source loading seat 200, and light emitting diode 204 is welded on the printed circuit board (PCB) 202.Rotating shaft 210 is arranged in the light source loading seat 200, and guide shoe 206 is sheathed in the rotating shaft 210, and guide shoe 206 is positioned at light source loading seat 200 belows.Roller 208 is sheathed in the rotating shaft 210, and roller 208 is positioned at guide shoe 206 belows.Light source loading seat 200 is a clearance fit with rotating shaft 210, so light source loading seat 200 210 rotations around the shaft.Guide shoe 206 is an interference fit with rotating shaft 210, so guide shoe 210 rotations around the shaft.
Printed circuit board (PCB) 202 usefulness flexible circuit boards (FPC) are connected on the light source driving circuit 120 (not illustrating), with this driven for emitting lights diode 204.
With reference to Fig. 3, it is depicted as the partial top view of the proving installation of adjustable light source spacing of the present invention.With the light guide plate of liquid crystal panel and various blooming piece after assembling on the load bearing seat 102 finishes, because take-up housing 116 is close to load bearing seat 102, therefore light emitting diode 204 can be adjacent to the incidence surface of light guide plate (not illustrating), afterwards an anti-dazzling screen 300 is placed in the slide rail 122 (not illustrating), it can slide on load bearing seat 102 along slide rail 122, adjusts the incidence surface of light emitting diode 204 and the distance between the panel operating space (Active Area) with this.Then according to the needs of testing, rotating drive screw rod 108, take-up housing 116 is because be subjected to the restriction of spacing cross bar 118 and load bearing seat 102, can't be along with coulisse 104 moves along guide rod 110, but because chute 106 is the oblique lines with slope, and take-up housing 116 is not restricted in the horizontal direction perpendicular to guide rod 110, therefore take-up housing 116 can move perpendicular to guide rod 110 along moving of guide rod 110 directions along with coulisse 104, until the distance between the take-up housing 116 is adjusted into required distance.
So just can carry out optic test to optical elements such as light guide plate, as under the condition of this kind light emitting diode 204 spacings, testing poor effect, then repeat the aforesaid operations step, can directly adjust the spacing between the light emitting diode 204, carry out new test, and need not to make again proving installation.
By the invention described above preferred embodiment as can be known, use the spacing that the present invention can the section of nothing adjusts light source, the time of so just saving making fixed light source spacing proving installation, shortened the R﹠D cycle and reduced R﹠D costs.
Though the present invention discloses as above with by way of example; right its is not in order to limit the present invention; any those of ordinary skill in the art; without departing from the spirit and scope of the present invention; when can being used for a variety of modifications and variations, so protection scope of the present invention is as the criterion when looking the scope that claims define.
