Abstract

To produce a light source coupler, a lead frame (80) is formed by connecting an electric conductor (41) for red, an electric conductor (42) for first green, and an electric conductor (43) for second green to a first electric conductor (51) and second heat conductor (52). A connection section (81) is used for the above connection, and the lead frame (80) is used as the starting material. A reflector member (60) is formed by resin molding, at a position where a light emission section (32) is formed, a red LED (61) and a first green LED (62) are installed on a first projection (54) provided on the first heat conductor (51), and a second green LED (63) and a blue LED (64) are installed on a second projection (55) provided on the second heat conductor (52). Then, the LED of each color and the electric conductor for each color are electrically connected by a bonding wire (not shown), and after that, the connection section (81) is punched to electrically separate connection between the LED of each color and the electric conductor for each color. Thus, a light emission device having the conductors for transmitting electricity and the conductors for transmitting heat is produced by the simpler method.
