Embodiment approach 1

[0038] Figure 1 to Figure 12 Embodiment 1 of the present invention is shown, figure 1 It is a figure which shows the structure of an endoscope system.

[0039] The endoscope system 1 includes a scope 2 , a light source device 3 , a video processor 4 , a monitor 5 , and a communication cable 6 .

[0040] The light source device 3 uses light-emitting elements of multiple colors as light sources. The light-emitting elements of multiple colors include, for example, light-emitting elements for emitting light of three colors constituting white light, specifically, red (R) light-emitting elements. A red LED (R-LED) 23r, a green LED (G-LED) 23g as a green (G) light emitting element, and a blue LED (B-LED) 23b as a blue (B) light emitting element. The emission spectrum of each light-emitting element is different, such as figure 2 As shown, the light emitted from the red LED 23r has a spectrum in the frequency band of red light R, the light emitted from the green LED 23g has a spe...

Embodiment approach 2

[0109] Figure 13 to Figure 17 Embodiment 2 of the present invention is shown, Figure 13 It is a figure which shows the structure of an endoscope system.

[0110] In this second embodiment, the same reference numerals are assigned to the same parts as those in the first embodiment described above, and description thereof will be omitted, and only differences will be mainly described.

[0111] In Embodiment 1 above, a single-color sensor is disposed near each of the color LEDs 23r, 23g, and 23b. A color sensor is configured at the position of the light.

[0112] That is, if Figure 13 As shown, a color sensor 31 is provided in the light source device 3 , and the color sensor 31 detects the intensities of the red light R, green light G, and blue light B by performing color sensing and outputs them to the control unit 21 . where, as later referred to Figure 14 As explained, the color sensor 31 is configured to include a color sensor 31w for sensing white light and a sensor...

Abstract

A light source device that generates light to be supplied to an endoscope, having: LEDs (23r, 23g, 23b) of various colors that emit light; a collimator lens (24) that receives and emits the emitted light; And illuminance sensors (27r, 27g, 27b), which are configured to be able to receive leaked light not used as illumination light in light emitted from various color LEDs (23r, 23g, 23b) and leakage light from various color LEDs (23r, 23g, 23b). 23g, 23b) and reflected by the collimating lens (24).

Description

technical field [0001] The present invention relates to a light source device that generates light to be supplied to an endoscope by a light emitting element and detects the intensity of the light. Background technique [0002] Conventionally, a xenon lamp or the like has been used as a light source device for illuminating the subject from an endoscope. However, with the spread of LEDs, light source devices using light-emitting elements such as LEDs have begun to be used in consideration of low power consumption and durability. practical application. [0003] LED is a light source that emits light in a narrower band than a xenon lamp that can emit white light alone, and therefore cannot emit white light alone. As a method of generating white light using an LED as a light source, for example, the following is known. of the three methods. [0004] Method (1) is to use a blue LED as the LED, irradiate the light emitted from the blue LED to the phosphor to output yellow light,...
