Abstract
An LED illumination structure without a light guide plate (LGP) includes an optical bottom plate, a plurality of LED illumination components arranged at least along one side edge of the optical bottom plate and a plurality of reflecting structures parallel to the LED illumination components formed on the optical bottom plate from two opposite side edges of the optical bottom plate to a center of the optical bottom plate. The reflecting structures are in a shape of tapered embossment and include a first side facing the center of the optical bottom plate and a second side facing the side edges of the optical bottom plate. An optical film is arranged in a raising direction of the reflecting structures of the optical bottom plate. The present invention is applicable to an illumination lamp for generating a uniform light emitting or may further be an illumination structure for projecting a light source of a bare-eyed 3D image.
