Abstract
A light-emitting device including a light-emitting element and a substrate where the light-emitting element is arranged. A housing part housing the light-emitting element and having a shape that is tapered upward from the substrate and a metal frame surrounding the light-emitting element and including the side face of the housing part made into an almost mirror-polished surface are provided on the substrate.
Claims9
A light-emitting device comprising:
- a light-emitting element, and
- a substrate where the light-emitting element is arranged, wherein
- a metal cover including a housing part for housing the light-emitting element and a through hole for transmitting light emitted from the light-emitting element, is provided on the substrate.
A method for manufacturing a light-emitting device including a light-emitting element, a substrate where the light-emitting element is arranged and a metal frame including a housing part for housing the light-emitting element, the housing part provided on the substrate and having a shape that is tapered upward from the substrate,
- the method comprising:
- a metal plate preparation step of preparing a metal plate including a plurality of metal frame forming areas where the metal frame is formed, and
- a housing part forming step of forming, by way of press working, the housing part on the metal plate corresponding to the metal frame forming areas.
A method for manufacturing a light-emitting device including a light-emitting element, a substrate where the light-emitting element is arranged and a metal frame including a housing part for housing the light-emitting element, the housing part having a shape that is tapered upward from the substrate, the substrate including a metal frame inserting part where at least part of the metal frame is inserted,
- the method comprising:
- a metal plate preparation step of preparing a metal plate including a plurality of metal frame forming areas where the metal frame is formed,
- a housing part forming step of forming, by way of press working, the housing part on the metal plate corresponding to the metal frame forming areas, and
- a cutting part forming step of forming on the metal plate a cutting part to allow the external shape of the metal frame to be deformable.
