Claim Text:
1. A light source system including an endoscope having an illumination section in which a pulse-driven light source is configured, and an illumination control section detachably connected to the endoscope and provided with a drive circuit that generates drive pulses for pulse-driving the light source, the light source system comprising: a connection section that detachably connects the endoscope and the illumination control section; a type information generating section that is provided at the endoscope and generates type information regarding the endoscope; a signal generating section that is provided at the endoscope and generates a signal indicative of a duty ratio of the drive pulses which is permitted to the illumination section, the duty ratio being defined in accordance with a type of the endoscope and corresponding to the type information; an endoscope type discriminating section that is provided at the illumination control section, receives the type information from the type information generating section through the connection section and discriminates the type of the endoscope based on the received type information; a light adjusting section that is provided at the illumination control section and outputs light-adjusted drive pulses having a duty ratio not greater than a permissible duty ratio permitted to the illumination section in accordance with information based on a discrimination result from the endoscope type discriminating section; and a limiting section that is provided at the illumination control section, and to which the light-adjusted drive pulses from the light adjusting section and the signal indicative of the duty ratio of the drive pulses which is permitted to the illumination section are inputted, the limiting section limiting the light-adjusted drive pulses inputted from the light adjusting section to have a duty ratio not greater than a duty ratio based on the signal from the signal generating section, and providing limited pulses to the drive circuit to output the drive pluses.
