Abstract
The utility model relates to an energy-saving and environment-protection sensing industrial film viewer, which comprises a box body. The middle part of the panel of the box body is provided with a film viewing window; the outside of the panel is provided with a sliding shielding plate; the side wall of the box body is provided with a power-supply switch and an adjusting switch; the inside of the box body is provided with a control circuit and lamps. The energy-saving and environment-protection sensing industrial film viewer is characterized in that: a, the lamps in the box body are formed by inserting a plurality of white LED lights into a circuit board to form a rectangular light source with length of 180 to 220mm and width of 50 to 60 mm, and the rectangular light source is arranged relative to the film viewing window; b, the middle position closing to the upper edge or the lower edge of the film viewing window is provided with a reflective sensor which is connected with a voltage adjusting unit in the control circuit through a photocoupler. The energy-saving and environment-protection sensing industrial film viewer overcomes problems of large power consumption and short service life of existing film viewer as well as inconvenient operation of manual switching of existing film viewer, is mainly used for film reading of industrial radiography film.
Description
(1) technical field: the utility model relates to a kind of sight sheet device of industrial radiography egative film, especially a kind of energy saving and environment friendly induction type industry viewbox.
(2) background technology: present its light source lamp of industrial viewbox is made up of 4 36WH type high brightness fluorescent tubes, 4 36W electric ballasts and control circuit, owing to adopted electric ballast, makes the light flicker free, opens fast, photochromic stable.But also have some problems simultaneously: owing to be fluorescent tube, power is big, and light decay is big, and the life-span is short, and frangible, colour temperature is impure, contains infrared ray in the spectrum, ultraviolet ray, and high voltage activates luminous, and security is low.And fluorescent tube contains mercury, mercurous, be unfavorable for environmental protection, and the casing volume is less, is easy to generate high temperature, influences lamp life.When existing on the other hand viewbox is read sheet, its brilliance control is to adopt foot-switch or hand switch control to light or extinguish viewbox, operate very inconveniently, and the switch that is difficult to guarantee light fixture causes the power supply waste or influences work efficiency with to place egative film synchronous.
(3) summary of the invention: the purpose of this utility model is exactly to solve the problems referred to above that existing industrial viewbox exists, and a kind of energy saving and environment friendly induction type industry viewbox is provided.
Concrete scheme of the present utility model is: improve at existing industrial viewbox, it has casing, the panel middle part of casing is provided with the sight gate, the panel outside is provided with the slip shutter, and wall box is equipped with power switch and by-pass cock, and control circuit and light fixture are installed in the casing, it is characterized in that: the light fixture in the described casing of a. is inserted into by a plurality of positive white LED lamps forms the rectangle light emitting source on the circuit board, the long 180-220mm of this rectangle light emitting source, wide 50-60mm sees gate relatively and arranges; B. near the centre position of the upper edge of seeing gate or lower edge reflection sensor being installed is connected with voltage-regulation unit in the control circuit by photoelectrical coupler.
For reducing the temperature in the casing in the utility model work, in the serviceable life of improving light fixture and electronic component, the relative rectangle light emitting source of mini fan is installed in casing in the utility model arranges.
For satisfying special needs, at wall box highlighted locking switch is housed in the utility model and connects control circuit, to cut off the control of reflection sensor, make light fixture be in the high brightness working condition to light fixture.
The utility model has thoroughly solved the shortcoming that brightness is low, heat is big, the life-span is short, power is big, colour temperature is impure of lamp tube type viewbox, and has not had infrared, ultraviolet in the spectrum owing to adopt positive white light LEDs as light source.Adopt reflection sensor in the utility model simultaneously, can finish the switching of light source switch automatically, and synchronous with putting into of film, energy savings can be avoided the stimulation of high light to operating personnel's eyes, improves the serviceable life of light fixture simultaneously, reduce labor intensity of operating personnel, increase work efficiency.The utility model is simple in structure, and is easy to operate, the efficient height, and energy consumption is low, long service life.
(4) description of drawings:
Fig. 1 is general structure master's cut-open view of the present utility model;
Fig. 2 is a circuit block diagram of the present utility model.
Among the figure: 1-slip shutter, the 2-casing, 3-sees gate, 4-LED lamp, 5-circuit board, 6-control circuit, 7-electric fan, 8-power switch, 9-by-pass cock, the highlighted locking switch of 10-, 11-reflection sensor.
(5) embodiment:
Referring to Fig. 1, the utlity model has casing 2, the panel middle part of casing 2 is provided with sees gate 3, the panel outside is provided with slip shutter 1, casing 2 sidewalls are equipped with power switch 8 and by-pass cock 9, control circuit 6 and light fixture are installed in the casing 2, particularly: the light fixture in the described casing of a. 2 is inserted into by the positive white LED lamp 4 of 400 0.03W forms the rectangle light emitting source on the circuit board 5, the optionally long 180-220mm of this rectangle light emitting source, wide 50-60mm (concrete optional length * wide=200mm * 55mm), see gate 3 relatively and arrange; B. near the centre position of the upper edge of seeing gate 3 or lower edge reflection sensor 11 is installed and is connected with voltage-regulation unit in the control circuit 6 by photoelectrical coupler, its circuit structure is referring to Fig. 2.Promptly constitute basic structure of the present utility model.
Preferred version of the present utility model is mini fan 7 relative rectangle light emitting sources to be installed arrange in casing 2, and at casing 2 sidewalls highlighted locking switch 10 connection control circuits 6 is housed, and to satisfy the needs of special circumstances, makes light fixture be in the high brightness state all the time.
