Abstract
The utility model provides a film viewing illuminator, which comprises a casing with lamp illuminated hole, a light tube installed in the casing and a control circuit used to control the operation of the light tube. The film viewing illuminator is characterized in that the light tube adopts with a gold-halogen light tube, and the control circuit is formed by an amperite and a trigger; one end of the amperite is connected with the input interface of an AC power supply, the other end of the amperite is connected with the power supply inputting terminal of the trigger, the other power supply inputting terminal of the trigger is connected with the other end of the input interface of the AC power supply and one end of the gold-halogen light tube, and the other end of the gold-halogen light tube is connected with the power supply outputting terminal of the trigger. Compared with the existing technology, The film viewing illuminator has the advantages that an industrial X-ray negative with the blackness value D between 4 and 5 can be observed by the brightness of the film viewing illuminator, and the observation range of use is wide.
Description
Technical field:
The utility model relates to a kind of lamp that is used to watch industrial X-ray negative.
Background technology:
Existing viewbox mainly is made of the control circuit of the casing that has the light-illuminating mouth, the fluorescent tube that is arranged on halogen tungsten fluorescent tube in the casing or high brightness and control halogen tungsten fluorescent tube or fluorescent tube work.This kind viewbox is subjected to the restriction of halogen tungsten fluorescent tube or fluorescent tube self property, and its brightness can only be observed the egative film of maximum blackness value D=4, is the egative film of 4-5 for blackness value D, then can not observe.
Summary of the invention:
Goal of the invention of the present utility model is to provide the viewbox of a kind of its sufficient brightness with the industrial X-ray negative of observation blackness value D between 4-5.
The utility model is to realize like this, comprise the casing that has the light-illuminating mouth, the control circuit that is arranged on interior fluorescent tube of casing and control lamp works, its special feature is that fluorescent tube adopts the Metal halogen lamp pipe, control circuit is made of ballast, trigger, one end and the AC power input interface of ballast join, the other end links to each other with the power input of trigger, a wherein end of another power input of trigger and another interface of AC power and Metal halogen lamp pipe joins, and the other end of Metal halogen lamp pipe links to each other with the power output end of trigger.During work, trigger, ballast moment, it is luminous that the Metal halogen lamp pipe is started to Metal halogen lamp pipe one high voltage startup electric current, the Metal halogen lamp pipe start luminous after, after the ballast decompression to the constant operating current of Metal halogen lamp pipe one.Because the Metal halogen lamp pipe more than the brightness height of the fluorescent tube of halogen tungsten fluorescent tube or high brightness, therefore, is enough to satisfy the requirement of the industrial X-ray negative of observation blackness value D between 4-5 when luminous.
Here, also be provided with the dimmer of regulating the brightness of Metal halogen lamp pipe, dimmer can be to establish a voltage regulator in the front of ballast, regulate input voltage by voltage regulator, to adjust the luminosity of Metal halogen lamp pipe, also can be to constitute by two or more ballasts in parallel, the ballast front switch of connecting, like this, select different ballast combinations by switch, thereby obtaining different electric currents comes to adjust the luminosity of Metal halogen lamp pipe, to satisfy the observation requirement of different blackness value egative films.
On power input interface and be connected to electric capacity, with the power loss of bucking-out system.
Compared with the prior art the utility model has its sufficient brightness with industrial X-ray negative and the observation scope of application big advantage of observation blackness value D between 4-5.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a circuit controling drawing of the present utility model.
Embodiment:
Now in conjunction with the accompanying drawings and embodiments the utility model is described in further detail:
As shown in the figure, the utility model is mainly by the casing 9 that has light-illuminating mouth 8, be arranged on the fluorescent tube that has reflection shield 32 in the casing 9 and control the control circuit formation that fluorescent tube 2 is worked, be provided with cooling fan 10 in casing 9 sides, its special feature is that fluorescent tube 2 adopts the Metal halogen lamp pipe, control circuit is by ballast 4, trigger 5 constitutes, one end and the AC power input interface of ballast 4 join, the other end links to each other with the power input of trigger 5, a wherein end of another power input of trigger 5 and another interface of AC power and Metal halogen lamp pipe 2 joins, the other end of Metal halogen lamp pipe 2 links to each other with the power output end of trigger 5, ballast 4 is by four ballast A, B, C, D is formed in parallel, ballast C, the D front also is in series with switch 6, on power input interface and be connected to electric capacity 7, mains switch 11, voltage dimmer 6 is arranged on casing 9 fronts.
Claims (3)
1, a kind of viewbox, comprise the casing that has the light-illuminating mouth, the control circuit that is arranged on interior fluorescent tube of casing and control lamp works, it is characterized in that fluorescent tube adopts the Metal halogen lamp pipe, control circuit is made of ballast, trigger, one end and the AC power input interface of ballast join, the other end links to each other with the power input of trigger, a wherein end of another power input of trigger and another interface of AC power and Metal halogen lamp pipe joins, and the other end of Metal halogen lamp pipe links to each other with the power output end of trigger.
2, viewbox according to claim 1, it is characterized in that also being provided with the dimmer of regulating the brightness of Metal halogen lamp pipe, dimmer can be to establish a voltage regulator in the front of ballast, also can be to be made of two or more ballasts in parallel, and the ballast front is in series with switch.
