Abstract:
It is an object of the present invention to provide a laser light source module capable of diverting current flowing to a laser diode when the laser diode does not emit light. A laser light source module includes a laser diode, a bypass circuit parallelly connected to the laser diode and diverting current flowing to a laser diode in an on state, a light detection circuit detecting laser light of the laser diode, and the bypass circuit switching circuit switching the bypass circuit to the on state in accordance with a control signal being input thereto, and the bypass circuit switching circuit can switch the bypass circuit to the on state in accordance with a state where the light detection circuit does not detect the laser light.

Claim (Index 8):
A method of specifying a failure laser diode to specify a defective laser diode in a light source device, wherein\n the light source device includes a plurality of laser light source modules being connected in series, each of the plurality of the laser light source modules includes:\n a laser diode; \n a bypass circuit being parallelly connected to the laser diode and diverting current flowing to the laser diode when the bypass circuit is in an on state; \n a light detection circuit detecting laser light of the laser diode; and \n a bypass circuit switching circuit switching the bypass circuit to the on state in accordance with a control signal being input to the bypass circuit switching circuit, \n in accordance with a state where the light detection circuit does not detect the laser light, the bypass circuit switching circuit can switch the bypass circuit to the on state, the light source device further includes:\n a controller individually outputting the control signal to the bypass circuit switching circuit of each of the plurality of the laser light source modules; \n a current source supplying current to the plurality of the laser light source modules being connected in series; and \n a voltage measurement circuit measuring voltage at both ends of the current source, and \n the method of specifying the failure laser diode includes steps that (a) the controller divides the plurality of the laser light source modules into two groups; (b) the controller obtains a voltage value at both ends of the current source while outputting the control signal for switching the bypass circuit to the on state to all of the laser light source modules belonging to one of the two groups; (c) the controller selects one of the two groups in accordance with the voltage value obtained in the step (b); and (d) the controller divides a group selected in the step (c) into two groups, wherein the controller performs the steps (b), (c), and (d) repeatedly, and when the group selected in the step (c) includes a single one of the laser light source modules, the controller specifies the laser diode included in the single one of the laser light source modules as a defective laser diode.
