no. 1 Embodiment approach ）

[0029] figure 1 It is a diagram showing the configuration of an endoscope system including the light source device according to the first embodiment.

[0030] like figure 1 As shown, an endoscope system 1 is configured to include an endoscope 2 for imaging a subject inside a living body, and a light source device 3 for supplying illumination light to the endoscope 2 for illuminating the subject.

[0031] The endoscope 2 is configured to be detachably attached to the light source device 3 via a not-shown connector or the like. The inside of the endoscope 2 has a light guide 4 that is inserted from the base end side to the front end side to guide the illumination light from the light source device 3, and diameter information related to the thickness of the diameter of the light guide 4 is stored (hereinafter The endoscope information storage unit 5 is also referred to as endoscope information).

[0032] The light-incident side end face of the light guide 4 (hereinafter also...

no. 2 Embodiment approach ）

[0050] Next, a second embodiment will be described.

[0051] Figure 4 It is a diagram showing the configuration of an endoscope system including the light source device according to the second embodiment. In addition, in Figure 4 in, right with figure 1 The same structures are marked with the same symbols and descriptions are omitted.

[0052] like Figure 4 As shown, an endoscope system 1 a is configured to include an endoscope 2 a, a light source device 3 a, and a processor 30 .

[0053] An objective lens (not shown) that forms an optical image of an illuminated subject is provided at the tip of the endoscope 2a. Furthermore, an imaging element 6 such as a CCD is provided at the imaging position of the objective lens. The imaging element 6 performs photoelectric conversion on the formed optical image to generate an imaging signal. Further, the imaging element 6 is connected to the processor 30 via a signal line, and outputs the generated imaging signal to the proce...

Abstract

A light source device (3) comprising: a light source unit (13) on which are disposed a plurality of LEDs for emitting illuminating light in an identical wavelength band; an optical system (14) for guiding the light emitted from the light source unit (13) to a proximal-end-side input end of a light guide (4) of an endoscope (2); and an LED controller (12) for controlling the LEDs so that the plurality of LEDs of the light source unit (13) are classified, on the basis of endoscope information in an endoscope information storage unit (5), into LEDs (22) serving as a first group of light sources for directing light to the vicinity of an optical axis of the input end, and LEDs (23) serving as a second group of light sources in the periphery of the LEDs 22 serving as the first group of light sources; and so that the output of the LEDs (23) serving as the second group of light sources is made lower than the output of the LEDs (22) serving as the first group of light sources.

Description

technical field [0001] The present invention relates to a light source device, in particular to a light source device for controlling a light source based on endoscope information. Background technique [0002] Conventionally, when observing or the like with an endoscope, a light source device that supplies illumination light for illuminating a site to be inspected to a light guide or the like provided in the endoscope is used. Figure 11A It is a figure which shows the structure of the conventional light source apparatus in the case where a thick-diameter light guide is connected, Figure 11B It is a diagram showing the configuration of a conventional light source device when a narrow-diameter light guide is connected thereto. [0003] like Figure 11A As shown, the conventional light source device 100 is composed of a light source 101 such as a xenon lamp, a light source group control unit 102 that controls the lighting of the light source 101, and a plurality of lenses 10...
