Abstract
A light emitting device has: a light emitting element; a metal member having a first face on which the light emitting element is mounted, and a second face that is on the opposite side from the first face; and a translucent member that seals part of the metal member and the light emitting element, the metal member has an element placement portion on which the light emitting element is placed, and a flat portion disposed around the element placement portion, a covering member is disposed on the second face side of the flat portion, and the top and side faces of the covering member are covered by the translucent member.
Claims17
A light emitting device comprising:
- a light emitting element;
- a metal member having a first face on which the light emitting element is mounted, and a second face that is on the opposite side from the first face;
- and
- a translucent member that seals part of the metal member and the light emitting element,
- the metal member has an element placement portion on which the light emitting element is placed, and a flat portion disposed around the element placement portion,
- a covering member is disposed on a side of the second face of the metal member at the flat portion, the translucent member being softer than the covering member, and
- an upper face and an outer side face of the covering member are covered by the translucent member.
A method for manufacturing a light emitting device, comprising the steps of:
- (a) disposing, in first molds, a metal member having an element placement portion on a first face of which is placed a light emitting element, and a flat portion disposed around the element placement portion, and forming a covering member that covers at least a second face, that is on the opposite side from the first face of the metal member at the flat portion;
- (b) placing a light emitting element on the element placement portion of the metal member;
- and
- (c) disposing the metal member covered by the covering member in second molds, holding an upper face and a lower face of the covering member with the second molds, and forming a translucent member that covers part of the metal member and the upper face and an outer side face of the covering member.
A light emitting device comprising:
- a light emitting element;
- a metal member having a first face on which the light emitting element is mounted, and a second face that is on the opposite side from the first face;
- and
- a translucent member that seals part of the metal member and the light emitting element,
- the metal member has an element placement portion on which the light emitting element is placed, and a flat portion disposed around the element placement portion,
- a covering member is disposed on a side of the second face of the metal member at the flat portion, and
- an upper face and an outer side face of the covering member are covered by the translucent member, the upper face of the covering member substantially coinciding with the first face of the metal member at the flat portion, and the upper face of the covering member and the upper face of the flat portion being covered by the translucent member.
