  • Patent number: 10703179
    Abstract: Discussed is a lighting apparatus having an organic light-emitting element configured as a transparent window and provided with an optical filter to prevent transmission of light when light having an intensity higher than a preset intensity is incident on the lighting apparatus so as to allow the lighting apparatus to be driven in a transparent mode, an opaque mode, and a lighting mode. The organic light-emitting element includes first and second electrodes and an organic emission layer disposed between the first electrode and the second electrode to emit light when a signal is applied thereto. The organic light-emitting element performs single-side emission or dual-side emission. The optical filter is formed of a photochromic material or an electrochromic material to make the lighting apparatus be opaque so as to adjust the transmissivity of light when the light having the intensity higher than the preset intensity is incident on the lighting apparatus.
