Abstract

A transparent luminescent sheet and a lamp apparatus using the same are disclosed. The transparent luminescent sheet realizes a lamp function through emission of light from a sheet thereof configured to be transparent and secures a desired luminous efficacy and a desired freedom of design. In the transparent luminescent sheet, transparency is enhanced in a turn-off state and, as such, visibility is secured at the inside and the outside. A lit image is realized through light during a light emission operation. In addition, light emitted toward the inside is shielded or reduced, thereby preventing indoor dazzling.
