Description
Technical field
The present invention relates to a kind of device that detects operation shadowless lamp illumination parameter.
Background technology
Operation shadowless lamp is one of hospital operating room visual plant, its illumination and do not have performance quality such as shadow degree and will concern operation quality and patient health, thereby, international, the domestic correlated quality test stone of all having issued is as international standard (IEC 60601-2-41) and domestic standard (YY 0102～0103-93) etc.Yet at present when operation shadowless lamp is carried out above-mentioned detection, there is no corresponding more accurate, advanced pick-up unit, pick-up unit that some are simple and crude and method can't guarantee the accuracy of testing result and the repeatability of testing conditions, are unfavorable for improving the quality of products and new-product development.The detection method of present more employing is that the lamp holder with operation shadowless lamp is placed on the support, on the surface level (XY coordinate surface) at 1000mm place below the lamp holder baseplane, having under two kinds of situations of shelter and have no occluder respectively, the variation of moving illuminometer and writing down illumination reading along eight directions, or, record and calculate each illumination characteristic parameter thus along the mobile illuminometer of Z axle and the variation of writing down illumination reading.This method has the following disadvantages: the first, because the limitation of lamp holder fixing means can not realize accurately that the optical axis of lamp holder and illuminometer detecting head surface are perpendicular; Second, illuminometer is popped one's head in accurate inadequately in the tolerance of the displacement of surface level upper edge all directions or corner amount, along the mobile illuminometer probe measurement illumination of the Z axle degree of depth time, the right alignment of probe axis and optical axis can't guarantee, and the also difficult control of the definite and position repeatability of displacement; The 3rd, when the shelter test is arranged, difficult accurate location of accomplishing shelter.These deficiencies all influence the efficient and the precision of testing.In addition, because the shadowless lamp lamp holder has different specifications, material is also relatively taken up an area of and taken to the support that needs to be equipped with different size usefulness during for check.
Summary of the invention
The objective of the invention is to disclose a kind of shadowless lamp illumination testing apparatus, overcome the following shortcoming that exists in the prior art: 1) can not on same pick-up unit, detect by the lamp holder to different size, must do special-purpose testing stand if need to detect; 2) because the limitation of lamp holder fixing means causes accurately realizing that the optical axis of lamp holder and illuminometer detecting head surface are perpendicular; 3) along the mobile illuminometer probe measurement illumination of the Z axle degree of depth time, the right alignment of probe axis and optical axis can't guarantee, and the also difficult control of the definite and position repeatability of displacement; 4) when the shelter test is arranged, difficult accurate location of accomplishing shelter.These deficiencies all influence the efficient and the precision of testing.
Shadowless lamp illumination testing apparatus provided by the invention is made up of frame, lamp holder fixed mechanism, guard mechanism and four parts of test board.Frame plays the effect that connects and support miscellaneous part, and the lamp holder fixed mechanism is moved up and down along its column, so that the measurement of the degree of depth of throwing light on.The main effect of lamp holder fixed mechanism is that the shadowless lamp lamp holder (it is not of uniform size generally to show as end circular diameter) different size correctly is fixed on the pick-up unit, promptly reach the dead in line of design axis (optical axis) Yu this pick-up unit of lamp holder, to guarantee the accuracy of testing result.Guard mechanism is mainly used at different parts increases shelter, and sham operated Shi doctor head does not respectively have shadow degree parameter to the occlusion state of shadowless lamp to measure.Test board is used to place the illuminometer probe and makes it to move along eight horizontal directions and Z-direction, to measure each illumination parameter.
Shadowless lamp illumination testing apparatus, the lateral edges of gantry base is connected with column, be with shifting axle in the column, shifting axle top affixed one " C " type support, three lamp holder fixators are connected on " C " type support with the central angle that equates, be connected with carriage on the column between " C " type support and the gantry base, the other end of carriage connects shutter; Be connected with square box on the gantry base, test board is above square box, the composite transmission that forms by the conical gear Meshing Pair in lifting shaft and the casing, feed screw nut is connected, and the power intake of test board jacking system is connected with the test board lifting handle; Worm and gear Meshing Pair in shifting axle and the casing is connected to this composite transmission of feed screw nut to the conical gear Meshing Pair again, and the power intake of shifting axle jacking system is connected with the shifting axle lifting handle; Be characterized in: the center three of the center of three formed centers of circle of evenly arranging of lamp holder fixator, shutter and test board is on same vertical axis on " C " type support, and this straight line is simultaneously perpendicular to three formed planes of evenly arranging of lamp holder fixator on test board plane and " C " type support.
Described lamp holder fixator comprises loam cake, lower cover, rotation nut, mobile screw and support bar, be characterized in: mobile screw is marked with scale, the one end connects support bar, and the other end of support bar has contact, and the axes intersect of three support bars is in the center of circle of " C " type support; In loam cake, the lower cover annular recess is arranged, the linear groove is arranged at the lower cover bottom, have externally threaded mobile screw one sidewall and be connected with the convex slide block, on the external cylindrical surface of rotation nut two straight-flanked rings are arranged, embed in the annular recess of lower cover, the internal thread of rotation nut is nested with the external thread of mobile screw, and the convex slide block on the mobile screw embeds in the linear groove of lower cover bottom.
Described shutter connects by shutter connecting rod symmetry, carriage one end is connected with the pallet of band scale, there is protruding axle the pallet center, the center of shutter connecting rod is on protruding axle, the carriage other end is hinged by the guard mechanism support on bearing pin and the column, also hinged a positioning rod between carriage and guard mechanism support.
Transverse axis one end of shifting axle jacking system is connected with a pair of worm and gear Meshing Pair, the other end connects a pair of conical gear Meshing Pair, one of them conical gear is connected with the leading screw bottom, the internal thread engagement of square thread on the leading screw and column bottom, and worm screw is connected with the shifting axle lifting handle.
The lifting shaft inside of test board jacking system is square thread, form a pair of feed screw nut gear train with leading screw, the leading screw lower end connects a conical gear, forms a pair of conical gear Meshing Pair with the conical gear of transmission shaft front end, and transmission shaft is connected with the test board lifting handle.
The center three of the center of three formed centers of circle of evenly arranging of lamp holder fixator, shutter and test board is on same vertical axis on " C " type support, and this axis is simultaneously perpendicular to three formed planes of evenly arranging of lamp holder fixator on test board plane and " C " type support.
Test board has index dial, and its center, top is connected with the central point that " U " type rotates chute, and scale is arranged on the chute.
Described shifting axle and lifting shaft are screw-nut structure, and the sidewall of shifting axle and lifting shaft has locating slot respectively, corresponding column inwall and fixedly the inwall of the base aperture of lifting shaft the convex edge, location is all arranged.
