Light-emitting device

A light-emitting device, comprising:

• a lead frame including a mounting region;
• at least two light-emitting diode (LED) chips disposed on said mounting region of said lead frame, a light being emitted from each of said at least two LED chips at a light-emitting angle which is not greater than 120°, each of said at least two LED chips including
• a substrate,
• a semiconductor light-emitting unit disposed on a surface of said substrate and having a lower surface and an upper surface which serves as a light-emitting surface and which is opposite to said lower surface,
• a first electrode and a second electrode which are disposed on said surface of said substrate,
• an electrically connecting structure disposed between said semiconductor light-emitting unit and said substrate so as to permit said first electrode and said second electrode to be electrically connected to said lower surface of said semiconductor light-emitting unit through said electrically connecting structure, and
• a first light-reflective layer disposed between said semiconductor light-emitting unit and said substrate, a first distance between said first light-reflective layer and said light-emitting surface of said semiconductor light-emitting unit being not greater than 10 μm;
• and
• an encapsulant which encapsulates said at least two LED chips on said lead frame.
