Abstract:
A light source circuit unit and a lighting device including the light source circuit unit that are configured such that a bent-type metal substrate is formed on an upper surface of the printed circuit board so that the occurrence of a defect due to circuit damage at a bent part upon bending the substrate can be prevented, and slimness and a heat-dissipation property of a device can be improved. The light source circuit board includes: a substrate having a first part with at least one opening portion, and a second part bent from the first part; a printed circuit board on one surface of the substrate; and a light source element mounted to the printed circuit board and inserted into the opening portion, the light source element emitting light to an opposing side of the substrate.
Abstract:
Embodiments relate to a light emitting device package having an improved luminous flux, and the light emitting device package includes a body including a cavity, a first lead frame and a second lead frame exposed on a bottom surface of the cavity and separate from each other by an electrode separating member, a first light emitting device disposed on the first lead frame, a second light emitting device disposed on the second lead frame, and a Zener diode disposed on the first lead frame or the second lead frame, and disposed more closely to the electrode separating member than to the first light emitting device and the second light emitting device. Here, the electrode separating member diagonally separate the first lead frame and the second lead frame along a width direction of the body.
