  • Publication number: 20250143046
    Abstract: A light emitting diode package structure includes one or more lead frame units, a light emitting element, and an encapsulation unit that completely covers the light emitting element and partially covers the lead frame units. Each lead frame unit includes a chip-mounted portion, a first electrode portion, and a second electrode portion. The first and the second electrode portion extend along a first direction, and are disposed on two sides of the chip-mounted portion. Each lead frame unit further includes multiple first connecting portions extending from the chip-mounted portion along the first direction, and multiple second connecting portions formed by extension of the first and the second electrode portion along a second direction. The light emitting element is fixed to the chip-mounted portion and electrically connected to the electrode portions. A lead frame that includes the at least one lead frame unit is also provided.

  • Patent number: 11774691
    Abstract: A light-emitting device and a light emitting module are provided. The light emitting module includes a housing, at least one light guide element, and at least one light emitting element. The housing includes at least one passage passing through its a first surface and a second surface, and a coupling portion formed on an inner surface adjacent to the second surface. The light guide element arranged in the at least one passage has a light emergent surface exposed at one end of the at least one passage and a light incident surface exposed at the other end of the at least one passage. The light emitting element is coupled to the housing by the coupling portion. The light emitting element includes a light emitting surface facing to the light incident surface of the light guide element and a soldering portion exposed from the housing.
