Here, at least some of the plurality of light sources have a rectangular planar shape, and the plurality of light sources are arranged so that at least one of long-axis direction or short-axis direction of at least some of the plurality of light sources are alternately changed in at least one of row direction or column direction.
Abstract:
A light emitting device package includes a package body, first and second lead frames located on the package body, a light source mounted on at least one of the first or second lead frames, a lens located on the package body, and a wavelength conversion unit partially located on the package body between the package body and the lens.
Abstract:
A light emitting device package includes: a light emitting device disposed on a substrate; a diffusion plate disposed on the substrate to surround the light emitting device; and a molding portion that is disposed on the substrate and has a shape of an aspheric lens whose center is recessed, The center of the molding portion is located on the same axis as the center of the light emitting device, and the diffusion plate may be interposed between the light emitting device and the molding portion. The molding portion having the shape of the aspheric lens whose center is recessed and the diffusion plate are employed to widely diffuse the light emitted from the light emitting device. Thereby, the efficiency of light can be increased, and manufacturing time and cost can be reduced. Simultaneously, a yellow ring phenomenon can be avoided.
