Abstract
The utility model relates to a minitype LED (light-emitting diode) endoscope lighting source. By adopting a method that a white light LED is combined with a red/green LED, the photometric brightness and the photochromism can be adjusted by a control circuit, so that the light source lighting with multi-color temperature is realized; the lighting source is arranged on a copper heat sink, so that the heat dissipation area is enlarged to a great extent, and the heat generated by running of a device is conveniently dissipated timely; and a reflector which is used for converging a light path and a condenser which is used for homogenizing a light ray are used on a light path, so that the use efficiency of the lighting source is greatly improved. By adopting the minitype LED endoscope lighting source, the portability of the endoscope lighting source is realized; the cost of the endoscope lighting source is reduced.
Description
Technical field
The utility model relates to a kind of optical system, particularly a kind of compact LED endoscope illumination light source.
Background technology
Traditional endoscope illumination generally all adopts Halogen lamp LED or the xenon lamp light source as illumination, adopt Halogen lamp LED and the main shortcoming of xenon lamp to be: 1, volume is big, because these lamps all are based on the luminous a kind of light source of spot light technology, itself has certain volume, again because this light source has very strong radiation at infrared band, need use this part energy of IR-cut filter disc filtering as endoscope illumination, power supply also needs bigger fan to dispel the heat; 2, energy consumption is big, has more energy to be consumed by infra-red radiation; 3, life-span weak point, the life-span of general Halogen lamp LED is about 1000 hours; 4, source-coupling efficiency is low, and the halogen bulb is luminous luminous on all angles of space, and it is very low to be coupled to fibre bundle aperture internal efficiency; 5, carry inconvenience, this light source also will use by fiber bundle coupling adding the power supply and blower equal-volume, gives to carry and brings certain difficulty.Along with development of semiconductor, the endoscope illumination that develops into of super brightness white light LEDs provides new light source at present, and it is little that LED has a volume, spectral region is concentrated, and light emission direction is concentrated, and the life-span is long, low cost and other advantages is widely used at lighting field.But also there are some technical problems as the endoscope illumination white light LEDs, the light energy that mainly is white light LEDs has very strong energy at the blue light range of 400-480nm, cause its colour temperature generally all more than 7000K, and general endoscope is 6000 ± 500K to the requirement of light source color temperature, needs to replenish the light energy of yellowish green scope.
Summary of the invention
The utility model be big at existing endoscope illumination light source volume, the life-span short, energy consumption big, carry the problem of inconvenience, proposed a kind of compact LED endoscope illumination light source, is a kind of portable, the life-span is long, cost is low endoscope cold light source; The colour temperature that can adjust simultaneously light source as required realizes the light illumination of polychrome temperature.
The technical solution of the utility model is: a kind of compact LED endoscope illumination light source, comprise shell, power supply, control circuit, light source, copper is heat sink, the parabolic shape speculum, the taper condenser, elastic interface, power switch, brightness regulating switch, the colourity by-pass cock, light source be fixed on copper heat sink on, copper is heat sink and housing contacts, illumination back reflection to the parabolic shape speculum outputs to the optical fiber connector of endoscope to the taper condenser from elastic interface, power supply is connected with control circuit by behind the power switch, brightness regulating switch and colourity by-pass cock are input on the control circuit, and control circuit outputs on the light source.
Described light source is the combination of white light and traffic lights.Described white LED lamp is positioned at the center of circle, lays red green LED lamp on circumference, and the led light source that red, green LED lamp is laid at interval and color is identical is symmetrically distributed.
Described power supply can be rechargeable battery.
The beneficial effects of the utility model are: the utility model compact LED endoscope illumination light source, characteristics portable, that the life-span is long, cost is low that this light supply apparatus has: the light illumination of realizing the polychrome temperature simultaneously; Improved source efficiency.
Description of drawings
Fig. 1 is the utility model compact LED endoscope illumination light source cutaway view;
Fig. 2 is the utility model compact LED endoscope illumination distribution of light sources figure;
Fig. 3 is the utility model compact LED endoscope illumination light source outline drawing.
The specific embodiment
LED endoscope illuminator cutaway view as shown in Figure 1, comprise power supply 2, control circuit 3, copper is heat sink 14, parabolic shape speculum 15, taper condenser 16, shell 1, light source 4 and elastic interface 18, power supply 2 links to each other with control circuit 3 through lead, the switch of control circuit 3 control light sources 4, the adjusting of brightness and photochromism.When circuit is connected, the direction of light directive elastic interface 18 after parabolic shape speculum 15 incides taper condenser 16 of light source 4 emissions, obtain homogenising through taper condenser 16 back light and handle, elastic interface 18 places are designed to the optical fiber connector with endoscope.
Power supply 2 adopts the rechargeable battery power supply in the utility model, and shell 1 back segment is designed to the plug 20 of civil power to battery charge.When needs charge to device, this device is directly linked to each other with civil power, just can charge.
Distribution of light sources figure as shown in Figure 2, light source design is white light and the pattern red, that green glow combines, be because the light energy of white light LEDs has very strong energy at the blue light range of 400-480nm, cause its colour temperature generally all more than 7000K, and general endoscope is 6000 ± 500K to the requirement of light source color temperature, needs to replenish the light energy of yellowish green scope.Given this, the utility model becomes form as Fig. 2 with light source design: white light LEDs 31 is in the center of circle, on the circumference of certain radius, lay red green LED32, the led light source that red, green LED lays at interval and color is identical is symmetrically distributed, wherein white light source can be a LED, also can be several combination.
In the utility model, light source 4 is installed on the copper heat sink 14, and copper is heat sink 14 to be contacted with shell 1, and contact portion is all used as diffusion sheet, and the heat that produces when making LED work can shed fast.
LED endoscope outline drawing as shown in Figure 3, power supply 2 links to each other with charging plug 20 through leads, when normal the use, turns on the power switch 19, regulates brightness and adjusts button 21 and photochromism adjusting button 22 and the brightness of light and colourity are reached need standard.The light that is sent by light source 4 incides taper condenser 16 after 15 reflections of parabolic shape speculum, incide then in the inner fiber of the endoscope that is connected with elastic interface 18, so standard compliant light is delivered to the place that needs illumination through optical fiber.
When needing to charge after use, optical fiber is disconnected from elastic interface 18, only needing this device is connected just can be to the charging of device internal battery on the civil power.
