Abstract: The light emitting device package of the present invention has a longitudinal direction (as viewed from above) and a transverse direction perpendicular to the longitudinal direction, and is provided with a first and second lead-frame lined-up in the longitudinal direction and molded resin holds the first and second lead-frames integrally. The package is characterized in that the first lead-frame has a main body and an extension that extends from the main body with a narrowed width towards the second lead-frame. Further, a recess is established in the bottom surface of the first lead-frame, and at least part of the exposed region of the bottom surface of the extension is separated from the exposed region of the bottom surface of the main body by the molded resin that fills the recess.

Abstract: A planar light source includes an irregular-shaped mounting substrate, light sources arranged along first and second directions in a plan view, and a light diffusion plate including a thick plate portion and a thin plate portion outward of outermost light sources in the plan view. In the first direction, a distance between an optical axis of one first distal-end light source of one array and an outer edge of the light diffusion plate is greater than a distance between that of another first distal-end light source of another array and the outer edge. In a plan view, the thin plate portion has a width along a straight line along the first direction from the optical axis of the one first distal-end light source toward the outer edge greater than a width along a straight line from the optical axis of the second distal-end light source toward the outer edge.

Abstract: A light emitting device includes a substrate, a plurality of light sources, a partitioning member, a light transmissive member, a plurality of reflecting portions. The light sources are arranged on the substrate. Each of the light sources has a light emitting diode. The partitioning member includes a plurality of wall portions defining a plurality of sections respectively surrounding at least one of the light sources, the wall portions including top portions. The light transmissive member is arranged above the light sources. The plurality of reflecting portions are arranged on a lower surface of the light transmissive member. Lower surfaces of the reflecting portions are positioned lower than apexes of the top portions of the wall portions of the partitioning member.

Abstract: A light source device includes a plurality of light sources arranged in a matrix, a substrate, and a reflective member. The reflective member includes first walls defining a first region entirely surrounded by the first walls in a plan view, and second walls located on an outer side of the first walls, the second walls defining a second region having an opening facing outside of the reflective member and a third region. An area of the second region is greater than an area of the third region in the plan view. The light sources are disposed respectively in the first region and in the second region while none of the light sources is disposed in the third region.

The reflective member includes first walls defining a first region entirely surrounded by the first walls in a plan view, and second walls located on an outer side of the first walls, the second walls defining a second region and a third region each only partially surrounded by the second walls in the plan view such that an area of the second region is equal to or greater than a half of an area of the first region and an area of the third region is less than the half of the area of the first region in the plan view. The light sources are disposed respectively in the first region and in the second region while none of the light sources is disposed in the third region.

Abstract: A light emitting device includes a resin package having a rectangular shape in a top view and two short-side lateral surfaces and two long-side lateral surfaces. The two short-side lateral surfaces include a first external surface and a second external surface located on an opposite side from the first external surface. The two long-side lateral surfaces include a third external surface and a fourth external lateral surface located on an opposite side from the third external lateral surface. The lead is not exposed on the third external lateral surface nor the fourth external lateral surface. The first lead is exposed at the first external lateral surface and the second external lateral surface, respectively flush with the resin member at the first external lateral surface and the second external lateral surface. The second lead is exposed at the second external lateral surface, flush with the resin part at the second external lateral surface.

Abstract: A method of determining a chromaticity rank of a light emitting device includes selecting the light emitting device having a chromaticity rank in a region surrounded by four defining points on a 1931 CIE Chromaticity Diagram. A ratio of a distance in a y-direction between, of the four defining points, two defining points furthest from each other in the y-direction to a distance in an x-direction between, of the four defining points, two defining points furthest from each other in the x-direction is 0.5 or less A peak light emission wavelength of the blue light emitting element is in a range of 447 to 452 nm, a peak light emission wavelength of the green light emitting element is in a range of 520 to 541 nm, and a peak light emission wavelength of the red light emitting element is in a range of 630 to 632 nm.
