Abstract
The utility model provides a slit-lamp microscope adopting an LED light source, which comprises a light source, a condenser system, a slit system, a slit object lens, a binocular microscope and a photosensitive system, wherein the light source comprises a slit-lamp light source. The utility model is characterized in that the slit-lamp light source is an LED light source which is positioned at thefront end of the condenser system. The slit-lamp microscope provided by the utility model adopts the LED as the light source, and effectively settles the defects of high power, heat generation, shortservice life, large color temperature variation in light adjustment of halogen tungsten lamp, instability, etc. when the halogen tungsten lamp and flash lamp are adopted as the slit-lamp light sourceaccording to prior art.
Description
[technical field]
This utility model relates to a kind of opticianry checkout facility, particularly a kind of slit lamp microscope that adopts LED as light source.
[background technology]
Slit lamp microscope is a kind of opticianry checkout facility commonly used.The slit lamp light source of existing slit lamp microscope adopts halogen tungsten lamp, flash lamp more.
Existing slit lamp microscope 10 ' structure as shown in Figure 1, comprise a slit lamp light source 110 ', this slit lamp light source 110 ' form by halogen tungsten lamp and flash lamp, the light that it sends, by a condenser system 120 ', one filter system 130 ', a fissure system 140 ' and crack object lens 150 ', formed slit lamp light beam 151 ', to tested eye 152 ' throw light on; Illuminated tested eye 152 ' imaging beam 153 ', through the visual 161 ' observation of a binocular microscope 160 ' confession, carry out the inspection of slit lamp microscope, supply photosensitive system 170 (film or CCD, cmos image sensor etc.) photosensitive imaging simultaneously, the image that is obtained can offer computer and handle, analyzes and file.
There is following shortcoming in the slit lamp light source that above-mentioned slit lamp microscope adopted: 1: power is big, heat is big; 2, the life-span is short; 3, luminous efficiency is low; 4, halogen tungsten lamp colour temperature instability, colour temperature changes greatly during especially by light modulation.
[utility model content]
The technical problems to be solved in the utility model, be to provide a kind of slit lamp microscope that adopts led light source, solved effectively that existing slit lamp microscope adopts that halogen tungsten lamp and flash lamp are big as the existing power of slit lamp light source, heating, short, halogen tungsten lamp colour temperature instability of life-span, the colour temperature variation waits shortcoming greatly during light modulation.
This utility model is achieved in that a kind of slit lamp microscope that adopts led light source, comprise a light source, a condenser system, a filter system, a fissure system, crack object lens, a binocular microscope and a photosensitive system, this light source comprises the slit lamp light source, wherein, described slit lamp light source is a led light source, and this led light source is positioned at the front end of condenser system.
Described led light source is selected the LED of different wave length for use according to the specification requirement of slit lamp microscope, can realize every function of slit lamp microscope, and the image that is obtained can offer computer and handle, analyzes and file.
The utlity model has following advantage: adopt that led light source has solved effectively that existing slit lamp microscope adopts that halogen tungsten lamp and flash lamp are big as the existing power of light source, heating, the life-span is short, the Halogen light colour temperature is on the low side, the colour temperature variation waits shortcoming greatly during light modulation.Because led light source has quick change brightness, having solved halogen tungsten lamp can only luminously continuously can not change brightness fast, and flash lamp can only glisten can not luminous continuously shortcoming, and the employing led light source can substitute halogen tungsten lamp and flash lamp simultaneously.
[description of drawings]
In conjunction with the embodiments this utility model is further described with reference to the accompanying drawings.
Fig. 1 is a slit lamp microscope optical principle sketch map in the prior art.
Fig. 2 is the slit lamp microscope optical principle sketch map that this utility model adopts led light source.
[specific embodiment]
See also shown in Figure 2, the slit lamp microscope 10 of employing led light source of the present utility model, comprise a led light source 110, one condenser system 120, one filter system 130, one fissure system 140, one crack object lens 150, an one binocular microscope 160 and a photosensitive system 170, this led light source 110 is positioned at the front end of this one-level condenser system 120, wherein, slit lamp microscope 10 of the present utility model adopts led light source 110 as the slit lamp light source, this led light source is positioned at the front end of condenser system, replaces light source 110 ' (see figure 1) of being made up of halogen tungsten lamp and flash lamp in the prior art.
Described led light source 110 can be selected the LED of different wave length for use according to the specification requirement of slit lamp microscope 10.
The light that described led light source 110 sends, by condenser system 120, filter system 130, through fissure system 140, crack object lens 150, formed slit lamp light beam 151 throws light on to tested eye 152; The imaging beam 153 of illuminated tested eye 152, through binocular microscope 160, observe for visual 161, carry out the inspection of slit lamp microscope, supply photosensitive system 170 (film or CCD, cmos image sensor etc.) simultaneously, the image that is obtained can offer computer and handle, analyzes and file.
Because the power consumption of LED is little, the life-span is long, spectral characteristic is good and can luminously continuously can change characteristics such as brightness again fast, can improve slit lamp microscope the slit lamp performance, improve microscopical observing effect, the image of acquisition better quality.
Claims (2)
1, a kind of slit lamp microscope that adopts led light source, comprise a light source, a condenser system, a filter system, a fissure system, crack object lens, a binocular microscope and a photosensitive system, this light source comprises the slit lamp light source, it is characterized in that: described slit lamp light source is a led light source, and this led light source is positioned at the front end of condenser system.
