Circuit board and lighting device having the circuit board

摘要

Provided is a circuit board including: a support substrate including a first region and a second region extending to be bent from the first region; light emitting devices mounted to the first region of the support substrate; and a bending portion bent between the first region and the second region, wherein the bending portion comprises: an interconnection line arrangement portion that crosses an interconnection line; and an interconnection line protection portion disposed on the periphery of the interconnection line, wherein the interconnection line protection portion protrudes more than the interconnection line arrangement portion.

主权项

1. A circuit board, comprising:
a support substrate including a first region and a second region extending to be bent from the first region; light emitting devices mounted to the first region of the support substrate; and a bending portion bent between the first region and the second region, wherein the bending portion comprises: an interconnection line arrangement portion that crosses an interconnection line; and an interconnection line protection portion disposed on the periphery of the interconnection line, and wherein the interconnection line protection portion comprises a dummy metal attached to the support substrate using an adhesive layer such that, in a first region not having the interconnection line passing therethrough, the interconnection line protection portion has an embossed structure that is protruded further than the interconnection line arrangement portion in the first region.
