Referring to fig. 1, an endoscope light source device according to an embodiment of the present invention includes: at least two light source units 100 emitting light of different colors; a plurality of lens assemblies 200, each lens assembly 200 including a convex lens 210 and/or a concave lens 220, each lens assembly 200 corresponding to one of the light source units 100, the lens assemblies 200 being configured to receive and collimate light emitted from the corresponding light source unit 100; a prism 300, the prism 300 having an exit surface 310 and a plurality of entrance surfaces 320, the light emitted from the lens assembly 200 entering the prism 300 through the corresponding entrance surfaces 320; the single chip microcomputer 400 is connected to the light source unit 100, and the single chip microcomputer 400 controls the light source unit 100 to be turned on and off.
The light source 100 is generally an LED lamp, and the light emitted from different light sources 100 has different colors, and generally three LED lamps, i.e., a green light lamp, a red light lamp, and a blue light lamp, are used as the light source 100, or an LED lamp capable of emitting white light and a plurality of light sources 100 capable of emitting different colors of light are combined by filters capable of emitting different colors of light. Each light source 100 corresponds to one lens assembly 200, and the lens assemblies 200 are mainly used for collimating and correcting the light emitted from the light source 100, that is, the light emitted from the light source 100 passes through the lens assemblies 200, and then becomes parallel light from the light emitted in different directions, and then enters the prism 300. Collimation is the conversion of diverging light into parallel light. The lens assembly 200 may be composed of a concave lens 220 or a convex lens 210 alone, or may be composed of a convex lens 210 and a concave lens 220 in combination, and the number of lenses is not limited whether the lens assembly is composed of one lens alone or two lenses in combination, and the order of mounting the convex lens 210 and the concave lens 220 is not limited, and may be selected according to actual situations. The light beams of different colors emitted from the plurality of light sources 100 are collimated by the lens unit 200, enter the prism 300 through the corresponding entrance surface 320, are mixed, and then exit the prism 300 through the exit surface 310 to be irradiated into the endoscope handle 1100. The single chip microcomputer 400 is connected with the light source devices 100 through a cable, and the worker controls the opening and closing of different light source devices 100 through the single chip microcomputer 400. When the LED lamp is used, the single chip microcomputer 400 can control the light source elements 100 to emit light with different colors according to actual needs, for example, only one light source element 100 can be turned on to emit monochromatic light, or two or more light source elements 100 can be turned on to emit mixed light, and when the light source elements 100 are three LED lamps, namely a green light lamp, a red light lamp and a blue light lamp, knowledge of three primary colors of light can be reasonably utilized to allocate light with different colors.
Referring to fig. 1, in some embodiments of the present invention, the single chip microcomputer 400 controls the intensity of light emitted from the light source unit 100.
The single chip microcomputer 400 adjusts the light by using a commonly used LED light adjusting chip on the market, the light adjusting chip is equipped with a PWM light adjusting circuit, and a worker can adjust the intensity of the light emitted from the light source device 100 by controlling the single chip microcomputer 400, which can also be referred to as the brightness of the light. PWM dimming controls the intensity of light by controlling the magnitude of the duty cycle, i.e., the ratio of the time that the circuit is on to off. When the light intensity emitted by the light source 100 is adjustable, the intensity of the emitted monochromatic light can be adjusted, the light source is suitable for a special working environment, and when the light emitted by the light source 100 is mixed, the light with different intensities is mixed, more color types can be prepared, and the worker can make better selections according to the effects generated by the light with different colors.
Referring to fig. 1 and 2, in some embodiments of the present invention, the sliding resistance wire 500 and the dimming knob 600 are further included, and the sliding resistance wire 500, the dimming knob 600 and the light source 100 are connected in series to form a circuit.
When the dimming knob 600 is rotated counterclockwise, the overall resistance of the circuit decreases, and the current in the circuit increases under the condition that the voltage is not changed, so that the power of the light source 100 may increase, that is, the intensity of the light emitted by the light source 100 increases; when the dimming knob 600 is rotated clockwise, the overall resistance of the circuit increases, and the current in the circuit decreases without changing the voltage, so that the power of the light source device 100 may decrease, that is, the intensity of the light emitted from the light source device 100 decreases, and when the dimming knob is rotated to the off position 510, the circuit is broken, and the light source device 100 is turned off. When the light intensity emitted by the light source 100 is adjustable, the intensity of the emitted monochromatic light can be adjusted, the light source is suitable for a special working environment, and when the light emitted by the light source 100 is mixed, the light with different intensities is mixed, more color types can be prepared, and the worker can make better selections according to the effects generated by the light with different colors.

Light emitted from light source 100 may be partially focused within lens assembly 200 or within prism 300 or within an endoscopic device or an endoscopic system or within a human body after passing through lens assembly 200, and even if not focused, the light impinging within the human body may damage delicate body lumens. Therefore, the optical filter 700 is installed in the lens assembly 200 to filter a part of invisible light, reduce the heat generated by the light, and only the visible light is retained for the convenience of observation and use of workers. The filter 700 may be an infrared cut filter 700, a short wave filter 700, or a combination thereof. Meanwhile, the optical filter 700 may be attached only to one end of the lens assembly 200 close to the light source 100, only to one end of the lens assembly 200 close to the prism 300, or to both ends of the lens assembly 200.
Referring to fig. 1, 3, 4 and 5, in some embodiments of the present invention, the present invention further includes a first moving mechanism 900, the first moving mechanism 900 is connected to the lens assembly 200 and the light source 100, and the first moving mechanism 900 is used for adjusting an incident angle of light emitted from the lens assembly 200 incident on the incident surface 320.
The first moving mechanism 900 can rotate the lens assembly 200 and the light source device 100 together, so as to adjust the incident angle of the light emitted from the lens assembly 200 incident on the incident surface 320. The endoscope light source device may not have a good angle at which light emitted from the lens unit 200 enters the prism 300 due to a certain damage to the device caused by an unexpected behavior such as a processing error, an error in assembling components, a material deformation after a long-term use, or a collision. When the endoscope light source device is actually used, if the angle at which light emitted from the lens unit 200 enters the prism 300 is not good, the effect of the generated light is also not good, so that the intensity of the light is not sufficient or the irradiation range becomes small, which is finally not favorable for a worker using the endoscope to observe, and the diagnosis effect is affected. When the first moving mechanism 900 is provided, the incident angle of light emitted by the lens assembly 200 and entering the prism 300 can be adjusted through the first moving mechanism 900, so that light emitted by the endoscope light source device achieves a better effect and is convenient for workers to observe.

The second gear 920 is connected with the adjusting knob 930 through a rod, the adjusting knob 930 and the second gear 920 are relatively fixed, so that the second gear 920 can be driven to rotate by rotating the adjusting knob 930, and the first gear 910 can be finely adjusted by meshing the second gear 920 with the first gear 910 and having fewer teeth of the second gear 920.
