Abstract
(EN)
The present application relates to a both-side light emitting lighting device, which maximizes a scattering effect so as to be capable of increasing light extraction efficiency, and can acquire high power efficiency as a both-side light emitting lighting device so as to be capable of increasing the lifespan of the lighting device, and comprises: a first light-output surface; a second light-output surface positioned to face the first light-output surface; a light-emitting element positioned between the first light-output surface and the second light-output surface; and a light extraction film including a substrate, which is positioned on the first light-output surface, has first and second surfaces facing each other, and is provided so that light is incident to the first surface and outputted to the second surface, and a plurality of pores irregularly distributed in the substrate, wherein the substrate allows the light to be scattered when the light transmits through the substrate, the scattering includes first scattering by the pores and second scattering by the first surface and/or the second surface, and the substrate is provided so that a first degree of scattering caused by the first scattering relatively differs from a second degree of scattering caused by the second scattering.
