Title: LIGHT SOURCE DEVICE AND ILLUMINATING DEVICE
Abstract:
Provided are a light source device wherein a power loss is reduced, and an illuminating device. A main module (10) is provided with a chip LED (1), a constant current power supply IC (12) which supplies the chip LED (1) with a constant current, a resistor (15) which adjusts the output current of the constant current power supply IC (12), connectors (CN1-CN4) for input/output, chip jumpers (2-9) and the like.  The electrical path of a connector (CN1) can be connected to an input terminal of a constant current power supply IC (12) by attaching the chip jumper (2) but not the chip jumper (3).  Other chip jumpers (4-9) are brought into the same state, and 24V connected to the connector (CN1) from the external can be supplied to the external through the connector (CN2), and the output current from the constant current power supply IC (12) can be supplied to the external through the connectors (CN3, CN4).
