Abstract
The utility model provides a light source used for a medical endoscope, and the light source is used for overcoming the defects of low brightness and low colour development property of an LED (Light Emitting Diode) used as the light source of the endoscope in the prior art. The light source used for the medical endoscope, provided by the utility model, comprises a shell, a red monocolour LED, a yellow monocolour LED, a green monocolour LED, a cyan monocolour LED, a blue monocolour LED, a purple monocolour LED, a lenses, three dichroic sheets and an X prism, wherein the shell is provided with a light hole; the shell, the monocolour LEDs, the lenses, the dichroic sheets and the X prism form six types of monocolour LED lights which are collimated respectively through six lenses; the three dichroic sheets are respectively used for combining collimated light beams of red and yellow LEDs, green and cyan LEDs and blue and purple LEDs; the X prism is used for combining light beams combined by the three dichroic sheet into a white light beam; the white light beam is focused by the lenses and then ejected out through the light hole; and the monocolour LEDs, the lenses, the dichroic sheets and the X prism are fixedly connected with the inner side of the shell. The light source provided by the utility model is high in brightness, high in colour development property and suitable for the use environment of the endoscope.
Description
Technical field
This utility model relates to a kind of lighting source, relates in particular to a kind of light source that is used for medical endoscope.
Background technology
More clearly observe in the patient body situation and obtain accurately photo in the body for ease of the doctor, the lighting source of medical endoscope requires to have high brightness and high-color rendering.LED has long, advantages such as reliability is high, brightness is high, luminous efficiency is high, energy-conserving and environment-protective of life-span as a kind of solid state light emitter, just is widely used in each field, and medical endoscope is endoscope illumination as light source through optical fiber with LED also.ZL200420082931.2 is said like patent, selects for use a LED lamp as light source.LED generally has white light LEDs and monochromatic LED.Though the color rendering index of white light LEDs is higher, because single led optical extend is big, use white light LEDs and the coupled efficient of optical fiber lower, be difficult to obtain the optical fibre illumination light source of enough high brightness.The spectrum spectrum width of monochromatic LED is generally narrower, and the color rendering index of gained light source is very low, and is visible, and single led light source as endoscope has shortcomings such as the not high enough or color rendering properties of brightness is on the low side.
The utility model content
This utility model has overcome the shortcoming that LED brightness is not high enough or color rendering properties is on the low side as endoscope illuminator of the prior art, and a kind of light source that is used for medical endoscope is provided.
This utility model realizes that the technical scheme that goal of the invention adopts is: a kind of light source that is used for medical endoscope comprises: housing, red, yellow, green, blue or green, blue, purple six kinds of monochromatic LEDs, lens, dichroic sheet and X prism; Described housing is provided with loophole; Housing, monochromatic LED, lens, dichroic sheet and X prism form six kinds of monochromatic LED light respectively through six collimated; Three dichroic sheets close bundle with the collimated beam of reddish yellow, Malachitum, royal purple LED respectively, and the X prism closes light beam behind the bundle with three dichroic sheets and closes and restraint into a branch of white light and scioptics focus on the syndeton that penetrates from loophole; Monochromatic LED, lens, dichroic sheet and X prism are fixedly connected with housing is inboard.
The beneficial effect of this utility model is: through with a plurality of monochromatic LED mixed lights, the spectrum of gained white light has included the scope of visible light basically, so its color rendering properties is high.Simultaneously; The spectral width of monochromatic LED is narrow; The light loss that every road monochromatic light passes through behind dichroic sheet and the X prism is few; Close the summation of the brightness of bundle back gained light source near six monochromatic LED brightness, have higher brightness, the final white light that obtains meets the high brightness that the medical endoscope lighting source should have, the requirement of high-color rendering.
Below in conjunction with the accompanying drawing and the specific embodiment this utility model is done further to describe.
Description of drawings
Fig. 1 is a kind of light-source structure sketch map that is used for medical endoscope of this utility model.
In the accompanying drawing, 1 is that monochromatic LED, 2 is that lens, 3 are that dichroic sheet, 4 is that housing, 4-1 are that housing loophole, 5 is the X prism.
The specific embodiment
As shown in Figure 1, a kind of light source that is used for medical endoscope of this utility model comprises: housing 4, red, yellow, green, blue or green, blue, purple six kinds of monochromatic LEDs 1, lens 2, dichroic sheet 3 and X prism 5.Housing 4 is provided with loophole 4-1.Each monochromatic LED 1 places the along of lens 2, and six lens 2 are respectively with red, yellow, green, blue or green, blue, purple six kinds of optical alignments that monochromatic LED 1 sends.Utilize the function of dichroic sheet transmissive a shade and another coloured light of reflection, use a dichroic sheet two bundle color combiners.Consider various monochromatic characteristics, reddish yellow, Malachitum, royal purple LED are divided into three groups, three dichroic sheets close bundle with the collimated beam of reddish yellow, Malachitum, royal purple LED 1 respectively.X prism 5 is formed by four corner cube prism gummeds, and diagonal two cemented surfaces are the dichroic sheet, and wherein one side has reflect red gold-tinted, the function of all the other coloured light of transmission, another side that reflection royal purple light, the function of all the other coloured light of transmission are arranged.Three dichroic sheets close light beam behind the bundle and further close through the X prism and restraint into a branch of white light.Synthetic white light focuses on through the 7th lens 2 and penetrates from loophole 4-1.Monochromatic LED 1, lens 2, dichroic sheet 3 and X prism 5 and housing 4 inboard fixed connections, the installation site is merged into suitable can realize light beam.Lens 2 can be selected spherical lens, non-spherical lens or battery of lens for use according to practical situation.
During actual the use, the white light that a kind of light source that is used for medical endoscope of this utility model is produced and the optical fiber of endoscope are coupled and can be embodied as endoscope illumination.
