Lead frame with unidirectional connecting ribs, light-emitting device

Abstract

This invention provides a lead frame and a light-emitting device with unidirectional connecting ribs. The lead frame includes multiple lead frame units arranged in an array. Each lead frame unit includes a metal substrate and an insulating portion disposed outside the metal substrate. Adjacent lead frame units are connected only through the metal substrate in a first direction, and have a hollow portion formed in a second direction. This invention can reduce defects such as poor sealing and warping caused by exposed metal substrates.

Claims

1. A lead frame with unidirectional connecting ribs, characterized in that it comprises a plurality of lead frame units arranged in an array, each lead frame unit comprising a metal substrate and an insulating portion disposed outside the metal substrate, adjacent lead frame units being connected only through the metal substrate in a first direction, and having a hollow portion formed in a second direction.

2. The lead frame as described in claim 1, wherein, The insulating portion has a breakable dividing line formed in the second direction, or the insulating portion is discontinuous in the second direction.

3. The lead frame as described in claim 1 or 2, wherein, The insulating part is formed with a reflective cup.

4. The lead frame as described in claim 3, wherein, The reflector cup contains a light-emitting element, which is electrically connected to the exposed metal substrate inside and outside the reflector cup.

5. A light-emitting device, comprising a lead frame unit, the lead frame unit comprising a metal substrate and an insulating portion disposed outside the metal substrate, wherein the lead frame unit has the metal substrate exposed only on both sides in a first direction, and is sealed by the insulating portion in a second direction.

6. The light-emitting device as claimed in claim 5, wherein, The insulating part is formed with a reflective cup.
