Abstract
A light emitting device includes a resin package including: a first lead and a second lead, each including a top surface and a bottom surface, and a first resin portion located between the first lead and the second lead and extending in a first direction; a first light emitting element and a second light emitting element arrayed on the top surface of the first lead in the first direction, the first light emitting element and the second light emitting element each including at least a first side surface; and an encapsulant located on the top surface of the first lead and covering the first light emitting element and the second light emitting element. The first side surface of the first light emitting element and the first side surface of the second light emitting element partially face each other.
Claims19
A light emitting device comprising:
- a resin package comprising:
- a first lead and a second lead, each including a top surface and a bottom surface, and
- a first resin portion located between the first lead and the second lead and extending in a first direction;
- a first light emitting element and a second light emitting element arrayed on the top surface of the first lead in the first direction, the first light emitting element and the second light emitting element each including at least a first side surface;
- a first wire electrically connecting the first light emitting element and the second light emitting element to each other;
- and
- an encapsulant located on the top surface of the first lead and covering the first light emitting element and the second light emitting element, wherein a portion of a top surface of the encapsulant is depressed, and a lowest portion of the top surface of the encapsulant is located at a center of the light emitting device or in a vicinity thereof, in a plan view;
- wherein the first side surface of the first light emitting element and the first side surface of the second light emitting element partially face each other;
- wherein a part of the first side surface of the first light emitting element and a part of the first side surface of the second light emitting element are located on the same imaginary straight line extending in a second direction perpendicular to the first direction on the top surface of the first lead;
- and
- wherein, in the plan view, a region at which a portion of the first side surface of the first light emitting element faces a portion of the first side surface of the second light emitting element is offset from the lowest portion of the top surface of the encapsulant, and a portion of the first wire is located in said region.
A light emitting device, comprising:
- a resin package comprising:
- a first lead and a second lead, each including a top surface and a bottom surface, and
- a first resin portion located between the first lead and the second lead and extending in a first direction;
- a first light emitting element and a second light emitting element arrayed on the top surface of the first lead in the first direction;
- a first wire electrically connecting the first light emitting element and the second light emitting element to each other;
- and
- an encapsulant located on the top surface of the first lead and covering the first light emitting element and the second light emitting element;
- wherein each of the first light emitting element and the second light emitting element has a quadrangular shape in a plan view;
- wherein, in the plan view, a diagonal line of the quadrangular shape of the first light emitting element and a diagonal line of the quadrangular shape of the second light emitting element are on the same imaginary straight line, and the first wire crosses said same imaginary straight line;
- wherein the first wire includes a first bending point, a second bending point, and a third bending point, the second bending point being located between the first bending point and the third bending point, and the first, second, and third bending points being located between an electrode of the first light emitting element and an electrode of the second light emitting element in the plan view;
- and
- wherein the second bending point is lower than the first bending point and the third bending point in a height direction.
