An LED lighting device comprising: a light source comprising a plurality of LED chips which are configured to emit lights having wavelengths which are different from each other; a first face sheet having a front surface and a rear surface, said rear surface being defined as a diffusing and reflecting surface being configured to diffuse and reflect the lights which are emitted from said LED chips, said first face sheet being disposed such that said rear surface being faced to said light source, said first face sheet having a center axis and a plurality of apertures, each said aperture having a width (b) which extends along a direction perpendicular to the center axis, and a depth (a) along the center axis; a reflection sheet having a second reflecting surface, said reflection sheet being disposed such that said second reflecting surface is faced to said rear surface of said first face sheet, said reflection sheet being spaced from said first face sheet by a predetermined distance, said second reflecting surface being configured to reflect the light, being reflected by said diffusing and reflecting surface, toward said first face sheet, wherein said light source is aligned with said center axis, said apertures being configured to pass the light which is reflected by said second reflecting surface, and each of said apertures having a shape so as not to pass the light, which is emitted by said light source and directly traveled from said light source to said apertures, whereby the light which is emitted from said light source is not passed through said apertures toward an outside of said LED lighting device without being subjected to any reflection, wherein each of said apertures has an opening dimension which is perpendicular to the center axis, said opening dimensions of said apertures being made smaller towards said center axis, each of said apertures is shaped to have an aspect ratio which is determined by a ratio of the depth (a) to the width (b), each of said apertures being shaped to have the aspect ratio so as not to directly pass the light, being emitted by said light source and directly traveled from said light source to said apertures, toward an outside of said LED lighting device without any reflection. a light source comprising a plurality of LED chips which are configured to emit lights having wavelengths which are different from each other; a first face sheet having a front surface and a rear surface, said rear surface being defined as a diffusing and reflecting surface being configured to diffuse and reflect the lights which are emitted from said LED chips, said first face sheet being disposed such that said rear surface being faced to said light source, said first face sheet having a center axis and a plurality of apertures, each said aperture having a width (b) which extends along a direction perpendicular to the center axis, and a depth (a) along the center axis; a reflection sheet having a second reflecting surface, said reflection sheet being disposed such that said second reflecting surface is faced to said rear surface of said first face sheet, said reflection sheet being spaced from said first face sheet by a predetermined distance, said second reflecting surface being configured to reflect the light, being reflected by said diffusing and reflecting surface, toward said first face sheet, wherein said light source is aligned with said center axis, said apertures being configured to pass the light which is reflected by said second reflecting surface, and each of said apertures having a shape so as not to pass the light, which is emitted by said light source and directly traveled from said light source to said apertures, whereby the light which is emitted from said light source is not passed through said apertures toward an outside of said LED lighting device without being subjected to any reflection, wherein each of said apertures has an opening dimension which is perpendicular to the center axis, said opening dimensions of said apertures being made smaller towards said center axis, each of said apertures is shaped to have an aspect ratio which is determined by a ratio of the depth (a) to the width (b), each of said apertures being shaped to have the aspect ratio so as not to directly pass the light, being emitted by said light source and directly traveled from said light source to said apertures, toward an outside of said LED lighting device without any reflection.
