Scuff plate

A scuff plate, comprising:

• a first light guide element having a groove of a predetermined shape formed in an underside of the first light guide element when viewed from below;
• a first light source that emits light to the first light guide element;
• a surface-shaped light emission element that is disposed below the first light guide element and that upwardly emits light differing in color from that of the first light source, the surface-shaped light emission element illuminating a background section that surrounds the groove;
• and
• a half mirror layer interposed between the first light guide element and the surface-shaped light emission element, said half mirror layer being disposed on an upper surface of a transparent sheet that comprises a color-printed layer disposed on an undersurface thereof,
• wherein the first light source is mounted on an upper surface of a circuit board that laterally extends in a direction of an extension of the half mirror layer,
• wherein the surface-shaped light emission element comprises a second light guide element and a second light source that guides light into the second light guide element, and
• wherein the circuit board comprises a double-sided printed circuit board, and the second light source is mounted on a bottom surface of the double-sided printed circuit board to form a single light source unit.

A scuff plate, comprising:

• a first light guide element having a groove formed in an underside of the first light guide element;
• a first light source that emits light toward the first light guide element;
• a light emission unit that is disposed below the first light guide element and that upwardly emits light differing in color from that of the first light source said light emission unit comprising a second light guide element and a second light source that guides light into the second light guide element;
• and
• a half mirror layer interposed between the first light guide element and the light emission unit,
• wherein the first light source is mounted on an upper surface of a circuit board that laterally extends in a direction of an extension of the half mirror layer, and
• wherein the circuit board comprises a double-sided printed circuit board, and the second light source is mounted on a bottom surface of the double-sided printed circuit board to form a single light source unit.
