1. A light-emitting device, comprising:
- a first lead frame and a second lead frame spaced apart from each other, the first and second lead frames each comprising a top surface, an opposing bottom surface, and sidewalls arranged between the top surface and the bottom surface; and
a light-emitting diode chip disposed on the top surface of the first or second lead frame, wherein;
each of the first lead frame and the second lead frame comprises a first undercut sidewall, a second undercut sidewall, and a third undercut sidewall that at least partially define a fixing space, the fixing space being formed by the undercut sidewalls of the first lead frame and the second lead frame,the top surfaces of the first and second lead frames are substantially flat, andthe first lead frame and the second lead frame face each other in a horizontal direction such that the first undercut sidewall of the first lead frame faces the first undercut sidewall of the second lead frame,the second undercut sidewall and the third undercut sidewall of the first lead frame are parallel to each other and perpendicular to the first undercut sidewall of the first lead frame, andthe second undercut sidewall and the third undercut sidewall of the second lead frame are parallel to each other and perpendicular to the first undercut sidewall of the second lead frame.

Abstract
A light-emitting device includes first and second lead frames spaced apart from each other, the first and second lead frames each including a top surface, an opposing bottom surface, and sidewalls arranged between the top surface and the bottom surface thereof, in which at least one of the first and second lead frames include three inset sidewalls that at least partially define a fixing space, the fixing space undercutting at least one of the first lead frame and second lead frame, a light-emitting diode chip disposed on the top surface of the first or second lead frame, and the top surfaces of the first and second lead frames are substantially flat.
