Abstract
The utility model discloses a film observation lamp box for medical staff to observe camera films such as X-ray films, CT films and the like. The lamp box comprises a rectangular box body, wherein, a translucent plate is arranged on the face of the box body, a plurality of LED elements are arranged in the box body, a metal heating panel is further arranged in the box body, the metal heating panel is provided with an insulating film layer and a plane circuit layer, the LED elements are welded on the plane circuit layer, and a diffusion reflection board is further installed on the plane circuit layer. With the advantages of simple structure and low manufacturing cost, the utility model can rapidly enable heat generated by the LED elements in service to disperse rapidly by transferring the heat through the insulating film layer to the metal heating panel, thereby prolonging service life of the lamp box, and guaranteeing the use security of the lamp box. Through reasonable configuration of positions of the LED elements, a film observation window can gain uniform brightness.
Description
Technical field
The utility model relates to the film viewing light box that medical personnel are used to watch shooting films such as X-ray, CT.
Background technology
Use LED to regulate easily owing to brightness as the light source of medical film viewing light box, casing thickness is little, is used by hospital.This film viewing light box comprises casing, and seeing on the sheet window has light-passing board, and there are a plurality of LED light emitting diodes the light-passing board back, and the casing diapire has reflecting plate.As the disclosed medical X-ray film film viewing light box of Chinese patent specification CN200956070Y, comprise casing, light-passing board is positioned on the box mouth, is equipped with the reflecting layer on the bottom in the casing, a plurality of LED light emitting diodes are distributed on the reflecting layer, and peach shape diffused reflector covers on the LED light emitting diode.CN201007759 discloses a kind of ultra-thin medical viewbox, and there is light-transmissive film in the front of shell, and there is reflector at the back side, is provided with main light source between light-transmissive film and reflector, and main light source is cold-cathode fluorescence lamp or LED luminous tube group.Be provided with LGP between main light source and reflector, by being arranged in order the back light system of forming by back light, backlight light-guiding plate, reflectance coating, back light is cold-cathode fluorescence lamp or LED luminous tube group between LGP and the reflector.
In order to make lamp box have enough brightness, the LED element needs intensive layout, and still, when environment temperature was higher, film viewing light box use meeting was seriously generated heat, and causes the LED element to quicken old and feeble and damages, and shortens lamp box service life.
In addition, the LED element uses the arranged in squares mode in the existing this lamp box, in foursquare center luminance shortage, causes and sees sheet window brightness irregularities.
Summary of the invention
The purpose of this utility model provides a kind of medical film viewing light box of the led light source that can fully dispel the heat.
The medical film viewing light box of the utility model comprises rectangular box, there is light-passing board in the front of casing, a plurality of LED elements are arranged in the casing, also has metallic heat radiating plate in the casing, metallic heat radiating plate has insulating thin layer and plane circuit layer, described LED element is welded on the planar circuit layer, also has the diffusion reflector on the planar circuit layer.
Above-mentioned LED element distribution mode is preferably: three adjacent arbitrarily LED elements constitute an equilateral triangle.
There is the ventilation cavity at the rear portion of metallic heat radiating plate, and the upper lateral part of this ventilation cavity is communicated with exhaust apparatus, makes near the hot gas of metallic heat radiating plate obtain getting rid of.
Metallic heat radiating plate can also further reduce the thickness of lamp box directly as the squab panel of lamp box.
The utility model simple structure, cheap, the heat that use LED element produces can conduct to metallic heat radiating plate by insulating thin layer, heat is scattered and disappeared rapidly, prolong lamp box service life, guarantee that lamp box is safe in utilization,, make sight sheet window obtain uniform brightness by the LED position of components is carried out reasonable disposition.
Description of drawings

Fig. 2 is the B-B cutaway view.
Fig. 3 is a transverse sectional view.
Fig. 4 is an A portion enlarged drawing.
The specific embodiment
Medical film viewing light box as shown in the figure comprises rectangular box 1, there is light-passing board 2 in the front of casing 1 as seeing the sheet window, metallic heat radiating plate 3 is arranged in the casing 1, metallic heat radiating plate 3 upper stratas are pressed with heat conductivility good insulation thin layer 4 and plane circuit layer 6, electrode as numerous LED elements 5 of lamphouse light source is welded on the planar circuit layer 6, be connected with 6 on planar circuit layer,, also have diffusion reflector 7 on the planar circuit layer 6 by 6 power supply of planar circuit layer.Because LED element 5 need not holed on insulating barrier with being connected of planar circuit layer 6, the thickness of insulating thin layer 4 is less, about 50~100 μ m, and the heat of LED element is easy to pass to metallic heat radiating plate 3 from insulating thin layer 4, thereby realizes efficiently radiates heat.Ventilation cavity 8 is arranged at the bottom of metallic heat radiating plate 3, and the upper lateral part of this ventilation cavity 8 is communicated with exhaust apparatus 9 and 10, and there is passage 11,12 ventilation cavity 8 belows, makes near the metallic heat radiating plate 3 hot gas be got rid of rapidly and exchange.
Owing in the casing a plurality of LED elements are arranged, the distribution situation of LED element exerts an influence to the brightness uniformity of seeing the sheet window, preferred distribution mode is: except that the LED element that is positioned at the edge, other be that adjacent arbitrarily three the LED elements 51,52,53 of peripheral LED element at center constitute an equilateral triangle with any one LED element 5.Like this, the LED element is arranged uniformly, sees the sheet window and obtains uniform brightness.
The material that metallic heat radiating plate 3 can further be thickeied or working strength is higher, as the aluminium sheet more than the thickness 1.0mm, also can suitably dispose reinforcement in the back of metallic heat radiating plate 3, metallic heat radiating plate 3 can reduce the thickness of lamp box and heat radiation easily directly as the squab panel of lamp box.
