Abstract: A vehicle interior lighting device includes a light-emitting portion, a case that includes a side wall surrounding the light-emitting portion and houses the light-emitting portion, and a plate-shaped lens fixed to the case so as to cover an opening of the case and an open end of the side wall defining the opening. Light emitted from the light-emitting portion can be extracted from the entire region of a light extraction surface of the lens including an edge without being reflected.

Abstract: An electronic device includes: a first element which generates heat, and a second element which generates heat; a lead frame which includes: a first portion on which the first element is mounted; a second portion on which the second element is mounted; and a high-heat resistance portion between the first portion and the second portion; and a resin portion which covers a part of the lead frame.

Abstract: A light emitting device includes: a first lead including a first base portion having a constant thickness and a first small-thickness portion having a thickness smaller than that of the first base portion; a second lead including a second base portion having a constant thickness and a second small-thickness portion having a thickness smaller than that of the second base portion; wherein the first small-thickness portion and the second small-thickness portion face each other with a gap interposed therebetween; the length of the gap is 0.9 to 1.2 times the thickness of the edges of the first small-thickness portion and the second small-thickness portion; the length of the bonding wire in a plan view of the light emitting device is smaller than a value obtained by adding the thickness of the base portion, a width of a mounting-disabled area, and a width of a bonding-disabled area.

Abstract: A light emitting device includes a light emitting element, a sealing material for sealing the light emitting element, a first filler included in the sealing material, and a second filler included in the sealing material. The second filler includes a particle diameter smaller than that of the first filler.
