反射鏡とで成り面輝度均一化手段が施されてなる
面光源モジユールにおいて、前記面輝度均一化手
段は、鏡面処理が施された前記反射鏡の反射面に
前記直管状光源からの距離が離れるにしたがい疎
となる網点状の散光処理が成されていることを特
徴とする面光源モジユール。 In a surface light source module comprising a straight tube-shaped light source and a reflecting mirror that covers the straight tube-shaped light source from the back side, and is provided with a surface brightness equalization means, the surface brightness uniformity means includes the reflective mirror that has been subjected to mirror finishing. A surface light source module characterized in that a reflective surface of a mirror is provided with a dot-like light scattering process that becomes more sparse as the distance from the straight tube light source increases.
