Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, the utility model embodiment provides a kind of simulated fixture backlight, comprising:
The method of the backlight state that above-mentioned simulated fixture simulation backlight is actual is specially: regulate the distance between light source 3 and the bottom reflection sheet 2, namely regulate the height of light source 3; Regulate the spacing between light source 3 and the light source 3, namely regulate the horizontal level of light source 3; Regulate the distance between optical film material 4 and the light source 3, namely regulate the height of optical film material 4.After above-mentioned three regulating steps, point bright light source 3, pass judgment on by the picture that shows on 5 pairs of optical film materials 4 of optical measuring instrument this moment, namely measure outgoing light homogeneity and/or the brightness of optical film material 4, if the outgoing light homogeneity of optical film material 4 and/or brightness do not reach standard, then repeat above-mentioned three steps the position of light source 3 or optical film material 4 is regulated, until the outgoing light homogeneity of optical film material 4 and/or brightness reach standard, then finished simulation backlight state.In addition, can also change the optical film material 4 of different materials, and pass judgment on by the picture that shows on 5 pairs of different optical film materials 4 of optical measuring instrument, simulate the backlight state to select better optical film material.
After having finished simulation backlight state, can further measure the back light source structure parameter by dip stick, the back light source structure parameter specifically comprises: the distance between the spacing between the distance between light source 3 and the bottom reflection sheet 2, light source 3 and the light source 3, optical film material 4 and the light source 3 and mixed light height, mixed light height are the distance between optical film material 4 and the bottom reflecting piece 2.
