ABSTRACT:
A light-emitting diode light source unit has a printed circuit board mounting a light-emitting diode (LED) element on its surface. Between the LED element surface-mounted on the printed circuit board and a wiring land formed on the printed circuit board, there is surface-mounted a reflector for directing a beam emitted from the LED element toward an object to be illuminated, and the LED element and the wiring land are connected via a bonding wire.
