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.
Claims15
A transparent luminescent sheet, comprising:
- a first transparent layer and a second transparent layer having transparency;
- an electrode layer stacked on the first transparent layer, the electrode layer having conductivity and comprising a luminescent structure;
- and
- a clear layer having transparency and being stacked to cover the electrode layer such that the clear layer is filled between the electrode layer and the second transparent layer,
- wherein a part of the electrode layer is subjected to an etching process to expose a part of the first transparent layer, and
- wherein the electrode layer is formed with a land in accordance with a black oxide treatment through a photo process, to dispose the luminescent structure on the land above the exposed part of the first transparent layer.
