To improve the consistency between pathological diagnosis and clinical diagnosis,a dimmable magnifying shadowless observation lamp was designed.With the use of high brightness light-emitting diode(LED)natural light as the light source,this observation lamp used a pulse width modulation(PWM)dimmer for electronic dimming,mainly consisting of a luminous system,optical magnifying glass,PWM dimmer,electronic ballast,matte diffuser lampshade,universal gooseneck,etc.Through practical application,it has been proven that the design of the observation lamp is reasonable,the operation is simple,the safety is good,and there is no cross contamination.Applied in pathological tissue embedding,it can observe from all angles and angles and the selection of materials is accurate,which is conducive to improving the pathological diagnosis rate.
