Abstract: A light emitting diode module includes a lead frame, a first light emitting diode chip, a second light emitting diode chip, an encapsulant, and a lens structure. The lead frame has a die-bonding surface and a side wall together defining an accommodating recess. The encapsulant is filled in the accommodating recess, and covers the first and the second light emitting diode chips. The lens structure disposed on the lead frame has a bottom surface, a reflective surface, a first, a second, a third, and a fourth light emitting curved surface. The light emitting curved surfaces are respectively disposed opposite to the bottom surface. An adjacent position among the light emitting curved surfaces is a lowest point nearest to the bottom surface. The first and the second light emitting diode chips are disposed at the projections of the first and the second light emitting curved surface on the die-bonding surface.
