In human body, the pathological changes that X rays can not show can be seen using endoscope, therefore it is highly useful to doctor.Such as, doctor
Optimal medical scheme is made accordingly can by the ulcer of endoscopic observation gastric or tumor.
After but the bulb of all cold light sources has certain service life, rated life time to reach, the probability that fracture of wire is scrapped
Can greatly increase.If bulb is scrapped in clinical operation way, lamp can only be changed manually, but as bulb was lighted after a period of time
High heat can be sent, needs wait for a period of time and bulb can just be changed after cooling down, and are that this can delay operating time,
Further jeopardize the life safety of patient, cause malpractice.
Meanwhile, when observing pathological changes by cold light source, often people's intracorporeal organ physiological condition is extremely complex, changeable, such as：Patient
There may be hydrops, product just, pressure fluctuation, internal organs wriggle etc., cause observed patient in extremely complex kinestate, because
This needs provides suitable brightness according to different irradiated sites and state so as to the effect for reaching diagnosis and treat.
Utility model content
In order to overcome the shortcomings of described in background technology, this utility model provides a kind of department of eye illumination cold light source, the photograph
Bright cold light source cost is relatively low, easy to use, and preferably, light modulation is reliable for Consumer's Experience sense.

For mutually isostructural axisymmetric aspheric surface optical plastic, the second lens and the 3rd lens along optical axis place it is in opposite direction.First
Lens are high temperature resistants using the purpose of spherical optics glass, and the second lens and the 3rd lens adopt axisymmetric aspheric surface structure, mesh
Be, while the very high efficiency of light energy utilization is ensured, to shorten optical tube length, reduce size.Light beam is saturating with the 3rd in the second lens
Between mirror, size increase is a lot, power dissipation, therefore at the second lens and the 3rd lens position, temperature is not high, can adopt heat-resisting
The poor optical plastic of property.Meanwhile, make the second lens and the 3rd lens along optical axis place it is in opposite direction, can further reduce system
Make complexity and cost.
Preferably, described trigger includes that the low frequency booster circuit being sequentially connected in series, high frequency booster circuit, high frequency trigger electricity
Road and protection circuit, are conducive to preferably protecting whole circuit.
Preferably, described radiator includes the radiated rib of multigroup parallel installation, and radiated rib thickness is between 20 ~ 30mm
Between, the spacing of radiated rib between 10 ~ 20mm is saved production material, reaches preferable radiating effect.
Preferably, described radiated rib is made up of lightweight metal material.
Preferably, described lightweight metal material is aluminium alloy.
The utility model has the advantages that：This utility model simple structure, easy to operate, cost is relatively low, Consumer's Experience sense compared with
Good, light modulation is reliable, due to arranging multigroup cold light source, when in use, when one group of cold light source breaks down, manually or automatically can cut
Other cold light sources are led in changing-over, it is ensured that operation is normally carried out, and multigroup cold light source shares a set of power supply unit and trigger, drop
Low manufacturing cost.
