The specific principle is as follows: firstly, a plurality of light through holes 38 are uniformly distributed on a light hole turntable 34 along the circumference, the light hole turntable 34 is driven to rotate by a stepping motor 33, so that the positions of the light through holes 38 with different diameters correspond to the positions of a light source 35, the light through holes 38 with different diameters can limit different light through amounts, and the light energy is limited in a physical current limiting mode; secondly, since the first metal electrode 73 is in contact with the electrolyte solution 77 and the second metal electrode 74 is covered with a thin first insulating layer 75, and the second metal electrode 74 is in contact with the electrolyte solution 77 and the oil droplets 78, the contact surface is the first insulating layer 75, and when a voltage is applied to the first metal electrode 73 and the second metal electrode 74, there is an electrostatic force, and on the contact surface between the second metal electrode 74 covered with the first insulating layer 75 and the electrolyte solution 77, the electric charge is gradually increased, so that the surface tension between the oil and the electrode is increased, and further, the curvature of the lens film between the two solutions is changed, thereby realizing the change of the focal length.
In summary, the embodiment of the invention provides a light-emitting quantity and light source irradiation angle adjustable light-feeding instrument, which can realize multi-gear adjustment of a light source, and compared with the prior art, the light source light-emitting quantity control gear is richer and finer in adjustment; in addition, the curvature of the liquid lens can be changed, so that the irradiation angle of light rays is changed, different irradiation ranges are realized, and the universality of the equipment is improved.
The foregoing is merely a preferred embodiment of the present invention, and it should be noted that modifications and substitutions can be made by those skilled in the art without departing from the technical principles of the present invention, and these modifications and substitutions should also be considered as being within the scope of the present invention. While there has been shown and described what are at present considered to be fundamental principles, main features and advantages of the present invention, it will be apparent to those skilled in the art that the present invention is not limited to the details of the foregoing preferred embodiments, and that the examples should be considered as exemplary and not limiting, the scope of the present invention being defined by the appended claims rather than by the foregoing description, and it is therefore intended to include within the invention all changes which fall within the meaning and range of equivalency of the claims.
