Abstract
A light emitting device with improved heat dissipation is provided. The light emitting device includes a first lead frame, a second lead frame, a light emitting element and a housing. The first lead frame includes a light emitting element mounting portion, a first heat dissipation portion extending from the light emitting element mounting portion in a first direction, and second and third heat dissipation portions extending from the light emitting element mounting portion in a second direction opposite to the first direction. The second lead frame extends in the second direction and is disposed between and spaced apart from the second and third heat dissipation portions. The light emitting element is mounted on the light emitting element mounting portion and is electrically coupled to the first and second lead frames. The housing encapsulates the first and second lead frames. The second and third heat dissipation portions have a first width and the second lead frame has a second width the same as or different from the first width.
