Abstract: The present invention provides a light-enhanced element including a transparent element including a fluorescent brightening agent, wherein the fluorescent brightening agent can absorb the first light emitted by a light-emitting element and subsequently emits the second light having a wavelength longer than that of the first light.
Abstract: There is provided an enhanced brightness light emitting device, comprising a light emitting element, and a transparent encapsulation layer which encloses the light emitting element. The transparent encapsulation layer includes a resin and a fluorescent material represented by the following general formula (I): wherein R is selected from one of the group consisting of phenyl substituted with alkoxy, substituted or unsubstituted anthracene group, substituted or unsubstituted pyrene group, and substituted or unsubstituted 9,10-anthraquinone group.
Abstract: There is provided a light emitting device for visible light generation, including a light emitting chip, which can emit a first light having a wavelength between 250 nm and 420 nm; an organic phosphor layer, which is formed by applying organic polymers on the output surface of the light emitting chip using vacuum evaporation, coating, screen printing, offset printing, sputtering, dripping, casting, or adhering method; and an encapsulation layer embedded with a plurality of nanograde crystalline grains, wherein the first light emitted from the light emitting chip can excite the organic phosphor layer, which subsequently emits a second light having a wavelength between 380 nm and 800 nm, and the second light and the first light are mixed within the encapsulation layer to produce visible light with excellent color uniformity outwards from the encapsulation layer.
Abstract: There is provided a white light emitting device including a light emitting chip, which can emit a first light having a wavelength between 340 nm and 495 nm; an organic phosphor layer, which is formed by applying an organic polymer on the output surface of the light emitting chip using coating, screen printing, offset printing, sputtering, dripping, casting, adhering, or vacuum evaporation method; and an encapsulation layer embedded with a plurality of nanograde crystalline grains, which encloses the light emitting chip and the organic phosphor layer, wherein the first light emitted from the light emitting chip can excite the organic phosphor layer, which subsequently emits a second light having a wavelength between 530 nm and 580 nm, and the second light and the first light are mixed within the encapsulation layer to produce a white light with excellent color uniformity and color rendering outwards from the encapsulation layer.
