Description
Technical Field
The invention relates to a light source quality detection device, in particular to a light source quality automatic detection device of an operating room shadowless lamp.
Background
The operation shadowless lamp is used for illuminating an operation position, provides enough central illumination to illuminate part of a patient body, and can reduce the shadow of a local working area caused by the shielding of an operator to the maximum extent, so that an operator can more intuitively observe small objects with low contrast at different depths in an incision and a body cavity. The operating shadowless lamp is one of the most basic and important devices in an operating room, and the quality and the performance of the operating shadowless lamp have direct influence on the quality of the operation. Therefore, quality inspection of the surgical shadowless lamp is necessary.
The surgical shadowless lamp advances along with the change of a light source, from a common shadowless bulb to a halogen lamp, and then to the current LED lamp light source, the development process mainly passes through three stages: 1. a hole-type operating shadowless lamp; 2. an integral reflective operating shadowless lamp; and 3, LED operation shadowless lamp.
(1) When the quality of the operating shadowless lamp is detected, the parameters of central illumination, shadowless rate, light spot distribution, light column depth, spectral characteristics and temperature rise of an illuminated surface need to be measured; the method specifically comprises the following steps: 1. the method for measuring the central illumination comprises the following steps: enabling the optical axis of the shadowless lamp to be vertically downward, and measuring the central illumination at the center of a light spot 1m below the lowest point of the light emission outer surface of the lamp holder; 2. the light spot distribution measuring method comprises the following steps: the diameter of the light spots and the distribution diameter of the light spots need to be measured, namely the diameters of circles with central illumination of 10% and 50% are obtained; four coordinate positions where the four illuminances on the cross section of the optical axis passing through the center of the light spot reach the central illuminance of 10 percent are measured, and the obtained d10The average value of (d), i.e. the spot diameter; four coordinate positions where the four illuminances on the cross section of the optical axis passing through the center of the light spot reach 50% of the central illuminance are measured, and the obtained d50The average value of (1), namely the spot distribution diameter; 3. and (3) measuring the shadowless rate: when the light beam is blocked by a baffle, the center of the light spot is measuredThe percentage of the illuminance of the quantity to the central illuminance, i.e. the shadow-free rate of the single shutter; 4. and (3) measuring the depth of the light beam: measuring the central illumination at the spot center 1m below the shadowless lamp light emitting outer surface, and moving the detection equipment up and down along the optical axis by taking the spot center as a base point until the moved position reaches a measuring point with the measured illumination as 20% of the central illumination. The distance between the upper and lower measuring points is the depth of the light column; 5. measurement of spectral characteristics: the color of the illumination source is measured at the illumination site using a spectroscopic illuminometer. Placing an instrument measuring probe on a testing working surface, reading and storing test spectrum data, wherein the number of test points in a large place is not less than 9, and the number of test points in a small place is not less than 3; 6. and (3) measuring the temperature rise of the irradiated surface: the temperature rise of the illuminated surface is converted into a total irradiance measurement. Enabling the optical axis of the shadowless lamp to be vertically downward, and measuring the total irradiance at the light spot center 1m below the lowest point of the light emission outer surface of the lamp holder; at present, a special detection device for detecting the operating shadowless lamp does not exist, and a method for detecting the shadowless lamp by using an illuminometer and an irradiation radiometer is mostly adopted, so that the optical axis of a lamp holder cannot be accurately perpendicular to the surface of a probe of the illuminometer; the measurement of the displacement or the rotation angle of the illuminometer probe on the horizontal plane along each direction is not accurate enough, when the illuminometer probe is moved along the Z axis to measure the illumination depth, the coaxiality of the axis of the probe and the optical axis cannot be ensured, and the determination of the displacement and the position repeatability are difficult to control; when the test with the shielding object is carried out, the precise positioning of the shielding object is difficult to achieve.
