In use, being put into endoscope by side, tested part is imaged using the photographing element of endoscope lens, by video
It spreads out on display, carries out discriminatory analysis in conjunction with experience.
Most of endoscope is attached to white light source, which is only used for illuminating.Current endoscope generally only has one
A light source input hole only irradiates white light for illuminating, and uncontrollable.To use other light sources, then need to carry out troublesome behaviour
Make.Part endoscope is also required to be observed using the light source of some special wavelengths simultaneously, to obtain more information.Multi-wavelength light
The case where image information that source obtains the irradiation at tested position can preferably react tested position after treatment is operator
Member provides the information for being more easy to judge.The controllability of light source also has a great impact to picture quality.It interior is peeped for existing
Mirror lighting system, it is clear that advantage can not be provided in these areas.In addition, the irradiation section of the endoscope of single light source irradiation is limited,
It needs to carry out many more manipulations to operation handle when in order to obtain enough information.In this case, the use for increasing endoscope is negative
Load, affects the judgement of result.
Summary of the invention
The invention mainly solves the technical problem of providing a kind of LED based endoscope multiple light courcess controllable Lighting System,
In endoscope lighting system while completing illumination task, the light that can use multi-wavelength is irradiated, and obtains more figures
As information.It can control the light and shade of different light by control system, can obtain in dark chamber has the image of characteristic information simultaneously
For post-processing.
The present invention is achieved through the following technical solutions, and the present invention includes PCB circuit board plate body, center through hole, red
Color LED light, green LED lamp, blue LED lamp, white led lamps, positive pole interface and control interface, interface of the ground wire and resistance,

The center of circle coincidence of plate plate body, center through hole, red LED lamp, green LED lamp, blue LED lamp, white led lamps are arranged in PCB
The front of circuit board plate body, positive pole interface and control interface, interface of the ground wire and resistance are arranged in PCB circuit board plate body
The back side；Red LED lamp is one, and blue LED lamp is one, and green LED lamp is one, and white led lamps are three, six LED
Lamp is respectively with red, white, green, white, blue, white sequence arranged clockwise among the PCB circuit board plate body on concentric circles；Power cathode
Directly it is connected with any one interface of the ground wire with controller cathode, as same ground wire；Controller and power input and power supply
Anode interface and control interface are connected.
Shape of the present invention is a circular ring shape PCB circuit board, and front includes the LED light of six different colours, the back side
There are power control line interface and resistance.
As endoscope illuminator, the present invention dimensionally has strict requirements.For example entirety PCB circuit board outer diameter needs are small
In 1cm, internal diameter needs the outer diameter greater than conventional endoscope.
In the present invention, in order to improve illumination level of the endoscope illuminator in dark chamber, selected power higher, size
Lesser LED light.Transmitting light has red respectively, green, blue, white.All LED light are distributed in the concentric of the Internal and external cycle of annulus
On circle, its bright and brightness can be separately controlled in all LED.
In the present invention, in order to reduce the size of integral illumination system, other circuit systems are totally placed in annulus back
Face, which includes the resistance and the external power interface and control interface for controlling access to regulate and control LED output characteristics.It draws
Line can be attached on endoscope connection to controller.It takes up space to reduce line, so that becoming large-sized.It will in the present invention
Circuit board bottom plate, which applies copper, becomes a monolith GND, and only need to GND be applied copper in line and be connect with bottom plate can be considered as ground connection.
Compared with prior art, the present invention has the advantages that are as follows: firstly, compared to common endoscope illumination system
System, the present invention possess up to 6 LED light sources, it is sufficient to meet the illumination and acquisition of information task under various complex situations.It opens simultaneously
When dynamic, the brightness of multiple light courcess is bigger, endoscope camera shooting of being more convenient for.Further, since each light source can be controlled separately, therefore interior peep
Mirror illumination system brightness is controllable.The distribution of LED light source central symmetry provides convenience for some algorithm requirements.LED light is controlled respectively
System can obtain different angle light source irradiation diseased region image, provide more available informations.LED light has red, green, blue
Color, white four kinds of colors, can also be replaced with the laser emitter of different wave length in the later period, is promoted and available is more helped with this
In the multispectral information of detection judgement.
