Abstract
The invention provides an LED array cold light source lighting system of an endoscope. The lighting system comprises a microscope, an upper light source, an lower light source, an electric power, a power changing switch and the like, wherein, the upper light source consisting of upper light emitting diodes is fixed by an internal and external support bracket, and the lower light source consisting of lower light emitting diodes is fixed on the bottom of the microscope body.
Description
Technical field
The present invention relates to a kind of new LED cold light source, belong to the medical apparatus and instruments scope.
Background technology
What traditional endoscope illuminator adopted is single light source, and its shortcoming is that brightness is limited, cannot be transferred to best sharpness when directly having caused endoscope to move in vivo.And conventional art designs is to strengthen the intensity of light source.
Summary of the invention
The object of the invention promptly remedies the shortcoming of above-mentioned light source, has installed two light sources behind microscope additional, can reach the visual effect of twice under the same intensity of light source.
The present invention relates to a kind of new LED cold light source, form, can better observe for the doctor by microscope, last light source, following light source, power supply, power change-over switch etc.
Advantage of the present invention is:
Low cost of manufacture, be easy to install, easy to use.
2. good looking appearance is simple in structure.
3. power saving, minimum, the long service life of caloric value.
4. light modulation is stable, reliable, and no thermal inertia, flicker free, no stroboscopic do not cause visual fatigue.
5. brightness height, target resolution height.
The specific embodiment
Below the specific embodiment of the present invention is further described:
The present invention by microscope, go up light source, light source, power supply, power change-over switch etc. are formed down, last light source is fixed, is gone up the light source light-emitting diode group by interior external support and becomes, the light source luminescent diode is formed under the following light source, this time light source is mounted on bottom the microscope body.Described power supply is by the wire connecting power permutator, and transfer switch connects each light emitting diode in the upper and lower light source by lead respectively.
Claims (3)
1, a kind of LED cold light source is characterized in that being made up of microscope, last light source, following light source, power supply, power change-over switch.
2, LED cold light source as claimed in claim 1 is characterized in that being applied to endoscopies such as hysteroscope and peritoneoscope.
3, LED cold light source as claimed in claim 1 is characterized in that light source fixes, goes up the light source light-emitting diode group by interior external support and become, and the light source luminescent diode is formed under the following light source, and this time light source is mounted on bottom the microscope body.Described power supply is by the wire connecting power permutator, and transfer switch connects each light emitting diode in the upper and lower light source by lead respectively.
