Description
Technical field
This utility model belongs to the LED lighting technical field, relates to a kind of LED of endoscope cold light source.
Background technology
Progress and development of science and technology along with society; Endoscope is widely used in clinical or medical research as the most frequently used armarium, and is big but traditional endoscope illumination light source has caloric value, and light source life is short; Change frequent, and shortcoming such as brightness of illumination is not ideal enough.
The utility model content
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, and a kind of LED of endoscope cold light source is provided, and it is reasonable in design, and is simple in structure, and brightness of illumination is high, and caloric value is little, long service life.
For realizing above-mentioned purpose, the technical scheme that this utility model adopts is: a kind of LED of endoscope cold light source comprises can; It is characterized in that: said can one end is positioned at can inside support one is installed; Said support one bottom is fixedly connected with pedestal, and said pedestal one side is equipped with the LED light emitting diode, and said pedestal opposite side is equipped with radiator; Said support one free end is equipped with the lamp condenser lens group; The said can other end is positioned at can inside support two is installed, and said support two free ends are equipped with the secondary condensation optical lens group, is positioned at support two bottoms on the said can optical fiber interface is installed; Said optical fiber interface one end inside is fitted with optical fiber, and the said optical fiber interface other end is equipped with the fiber optic line receiving system.
On the said radiator radiator fan is installed.
Said can is cylindric.
This utility model compared with prior art has the following advantages:
(1) design of the LED of this endoscope cold light source is very reasonable, simple in structure, compact.
(2) LED of this endoscope cold light source set inside has lamp condenser lens group and secondary condensation optical lens group, thereby its brightness of illumination is very high.
(3) LED of this endoscope cold light source is a led light source, and its caloric value is very little, and itself is provided with heat abstractor, thereby its service life is very long, has avoided the light source frequent change.
Through accompanying drawing and embodiment, this utility model is done further detailed description below.

The specific embodiment
A kind of LED of endoscope cold light source as shown in Figure 1 comprises can 12, and said can 12 is cylindric.Said can 12 1 ends are positioned at can 12 inside support 1 are installed; Said support one 6 bottoms are fixedly connected with pedestal 2; Said pedestal 2 one sides are equipped with LED light emitting diode 5; Said pedestal 2 opposite sides are equipped with radiator 4, and said support one 6 free ends are equipped with lamp condenser lens group 3, and said can 12 other ends are positioned at can 12 inside support 29 is installed; Said support 29 free ends are equipped with secondary condensation optical lens group 7; Be positioned at support 29 bottoms on the said can 12 optical fiber interface 8 is installed, said optical fiber interface 8 one end inside are fitted with optical fiber 11, and said optical fiber interface 8 other ends are equipped with fiber optic line receiving system 10.
As shown in Figure 1, on the said radiator 4 radiator fan 1 is installed, radiator fan 1 can help radiator 4 heat radiations better.
The work process of the LED of this utility model endoscope cold light source is: at first the LED of this endoscope cold light source is installed in the operating position; Open LED light emitting diode 5; Open radiator fan 1 simultaneously; LED light emitting diode 5 is luminous, and lamp condenser lens group 3 optically focused of light through installing at support one 6 free ends are being installed in through the irradiate light that converges on the secondary condensation optical lens group 7 of support 29 free ends and once more light are being converged; The irradiate light of passing through secondary condensation then is on fiber optic line receiving system 10, and light conducts to irradiation position through optical fiber 11.
The above; It only is the preferred embodiment of this utility model; Be not that this utility model is done any restriction; Every according to this utility model technical spirit to any simple modification, change and equivalent structure transformation that above embodiment did, all still belong in the protection domain of this utility model technical scheme.
