Abstract
A plurality of separate lead frames can be insert-molded in a reflector composed of a white resin having a high reflectivity to form a package for an LED device. A cavity is formed in the reflector. The cavity can have an inner circumferential surface that opens wider in an upward direction. Cups can be located in the cavity. Each cup has an outer wall that can be in the form of a cylinder with the bottom formed of each of two separate lead frames. A red LED chip and a green LED chip can be adhesively fixed to the lead frames located on the bottoms of the respective cups. The LED chips can have lower electrodes, which are electrically brought into conduction with the lead frames one by one. The LED chips can also have upper electrodes, which are electrically brought into conduction with the lead frames one by one via bonding wires. A light transmissive resin can be filled in the cavity.
