It also can provides the good illumination. when doctor inspecting ,photographing, video recording the body cavity organ. .Character Su
3、mmary1. Using the advanced electrically controlled switching circuit, provides the power source for the high-pressured short arc. Selects the ballhigh pressure short arc gas light as the luminophor. Under the electric circuit high pressure, causes the light bulb positive and negative electricity int
4、erelectrode shape electric discharge to shine, produces ultraviolet from to the infrared entire spectrum radiation light source, the visible range light extremely resembles the whitelight.2. Power source output current is ripple small and invariable, make the arc light stable, the optical efficiency
5、 high, color is good. In order to avoid other medical equipment movements produces high frequency chirp wave disturbance normal work, We joined the low pass filter system in the power source, enhanced the entire machine stability, thus obtains satisfaction in the clinical observation photograph work
6、 .3. The cold light source output strong and the weak, is depends on operating the kneadingboard to touch the switch to control. In order to guarantee in the light source work movement stable and reliable, we used three air blowersseries wind eta path strong radiation design, makes the radiation ful
7、ly, guarantees the entire machine work stable.4. Carried out in the design and the production GB9706.1 Medical electric appliance equipment - first part: Safe general request, can guarantee its security.Attention: The cold light source does not have directly to use in an eye illumination. Main techn

11、onnection.Operation description1. guarantees the segment correctly, the light beam and the luminous efficiency mouth connection is reliable2. turns on the cold light source power switch, the cooling system starts to work. The light bulb lightens immediately, the lightsource starts to work.3. press b
12、utton may transfer the degree of illumination from biggest to zero. move brightly, moves darkly.When finish the job, adjust the lightsource brightness to the lowest, later closes the power switch, guarantees the entire machine full cooling before turn off the machine. Notice 1.When work, the cold li
13、ght source should lay aside toventilates and the steady place, Radiation hole and the back cover supposed to maintain the 15cm space length2.In work do not let the patient contact the cold ligh tsource3.After light sources start for 120 seconds, the facula to appearthe vibration belong to the normal
14、 phenomenon4.After cold light sources open, do not to look straight ahead the optical cable with the naked eye or the light loses the pore, prevent eye to receive the injury.5.When work, the engine case does not have to lay aside other goods6. The cold light source is loaded with the ultrahigh volta
15、geshort arc mountain lamp,do not fierce vibration,be careful of transportation.7. When do not use cold lightsources, should deposit toventilates and the dry place, and must add the safety mask.8. Carry on the disinfection with the ultraviolet sterilization regularly. 9. Has the high tension circuit,
16、 do not turn on the engine case besides he machine repair personnel.Change the lamp 1. When replaces the light bulb, should select same model highpressure short arc xenon or the same parameter import light bulb,can guarantees the cold light source normal 2. Closes the power switch3. Machine box lid
17、opening slowly, turn on the engine s ventilator lap, twist the light bulb negative pole segment and three anchor screws, will take out the old lightbulb, and exchanges the new light bulb.4.When install new light bulbs, must pay attention to the light bulb localization aim at light gap, screws tight
18、three fixed anchor screws, twists the ventilator lid.5. From the engine case base ,pulls out the light bulb anode segment with the orange(black) to fix together on the wiring column, covers the back lid .Attention:The light bulb anode segment, does not have to touch with cold light source engine cas
19、e and must maintain the enough distance.Troubleshooting（be supposed to operate by specialist)1. After turns on the power source, the indicating lamp is not bright, the air blower and the light bulb do not work1) inspects whether the alternating current supply is normal2) inspects whether the fuse bl
20、ows a fuse. The fuse altogether has two behind the cabinet, is the tubular5A2. air blowers work but the Xenon is not bright1) turns on the cabinet, dismantles the line board and the trigger two attachments, with the direct current electric instrument measuring circuit board output voltage, the norma
21、l voltage is about300V, if obtains the electricity reduce or not to have the voltage, then there is the electric circuit board problem2) When the electric circuit board or the voltage are normal, must inspect the light bulb s quality. Xenon light bulb shell damages, the light bulb electrode without
22、the break does not have fuse, the light bulb endophragm evaporates ,the black spot without the metal should judge the light bulb is good3) if the light bulb does not have the question, then is the trigger breakdown4)When replaces the trigger, must pay attention to its model, Do not make a mistake the input & output and the cathode connection, otherwise will damage the light bulb
