The invention relates to a light spot regulating device of a shadowless lamp. The light spot regulating device comprises a lamp body provided with a concave spherical surface, wherein a plurality of light source module mounting bases are distributed on the concave spherical surface of the lamp body; light source modules are arranged on the light source module mounting bases through supports and transmission assemblies; the supports are fixedly connected with the corresponding light source module mounting base and are movably hinged with the light source modules through support shafts on the supports; the support shafts are vertical to the radial positions of the lamp body, so that light spots are positioned on the central axis of the lamp body when the light source modules regulate light emergent angles; and the transmission assemblies are worm gear mechanisms which are driven by a motor connected with a control circuit and are arranged between the light source modules and the supports so as to control the light source module to swing back and forth around the support shafts to regulate the light emergent angles. By utilizing the structure, the light spot regulating device provided by the invention has the characteristics of compact structure, easiness in assembly and high regulation accuracy of the light emergent angles of the light source modules.
Description
technical field [0001] The invention relates to the technical field of lighting fixtures, in particular to a light spot adjustment device for a shadowless lamp. Background technique [0002] With the continuous development of lighting technology, various lamps are constantly being introduced. As a special type of lamps in lamps - shadowless lamps are widely used in medical operating tables. [0003] The existing medical shadowless lamp, the lamp body looks like a concave spherical surface as a whole, the inner wall of the concave spherical surface where the light source is distributed, and the light source is also distributed spherically, so all the light will be concentrated on the center of the spherical surface. After the lamp body is made, the position of the center of the sphere is fixed. Therefore, it is necessary to adjust the angle between the light source module and the center axis of the sphere, so that the concentrated light spot position of the light source modu...
