Shadowless deflectable LED lighting source for operation

Abstract

The invention discloses a shadowless deflectable LED lighting source for an operation. The shadowless deflectable LED lighting source comprises a base, a mask mounting frame, overturning lamp set units, a magnetic deflection control unit and a light-transmitting mask. The mask mounting frame is narrower than the base. Each overturning lamp set unit comprises a deflection frame and a plurality of light-emitting wafers arranged on the deflection frame at intervals. Permanent magnets are fixed to the inner sides of the two ends of the deflection frame respectively, rotating shafts are arranged onthe outer sides of the two ends of the deflection frame respectively in a protruding mode; the rotating shafts pass through the mask mounting frame outwards and then are rotationally connected into through holes of stand columns; conducting electrodes are embedded in the rotating shafts and a conducting layer is arranged on the inner top face of the deflection frame and electrically connected with the conducting electrodes. The magnetic deflection control unit comprises a support, and electromagnets are fixed to the two ends of the support respectively. The deflection angle of each overturning lamp set unit in the LED light source can be independently adjusted, multi-directional illumination can be achieved, the width of an illumination area can be increased, the light direction can be controlled, targeted illumination is achieved, the rotation inertia is greatly reduced, and deflection response is fast.

Description

technical field [0001] The invention relates to a shadowless and deflectable LED lighting source for surgery. Background technique [0002] Due to its advantages in size, brightness, controllability and lifespan, LED light sources gradually replace traditional light sources and are more and more widely used in all aspects of life. [0003] In the currently known LED light source structures, the basic light-emitting units are all fixed structures. However, in many cases in the actual use of LED light sources, the lighting range of the light source is required to be wider or the lighting range is variable; The unit is a fixed structure, so that to achieve the purpose of variable lighting range, the entire LED light source needs to be a movable structure. Such an overall mobile structure has a large rotational inertia due to the large volume and weight of the entire LED light group. The deflection responsiveness is poor, and the volume of the entire deflection mechanism is cor...

[0003] In the currently known LED light source structures, the basic light-emitting units are all fixed structures. However, in many cases in the actual use of LED light sources, the lighting range of the light source is required to be wider or the lighting range is variable; The unit is a fixed structure, so that to achieve the purpose of variable lighting range, the entire LED light source needs to be a movable structure. Such an overall mobile structure has a large rotational inertia due to the large volume and weight of the entire LED light group. The deflection response is poor, and the volume of the entire deflection mechanism is correspondingly large, which cannot adapt to various increasingly miniaturized use occasions today.
