Embodiment Construction

[0029] The following will be combined with Figure 1-6 For further details:

[0030] A method for adjusting the light spot of a shadowless lamp, the method comprising: providing a lamp body 10 with a concave spherical surface, a plurality of light source module mounting seats 20 are distributed on the concave spherical surface of the lamp body 10, and a plurality of light source modules 30 are respectively arranged correspondingly. On the light source module mounting base 20 so that the light spot irradiated by the light source module 30 is located on the spherical center axis of the concave spherical surface, the bracket 40 is fixedly connected to the corresponding light source module mounting base 20, and the bracket 40 passes through the bracket 40. The bracket shaft 41 is hinged with the light source module 30, and the bracket shaft 41 is perpendicular to the position of the radius of the lamp body 10; there is a worm gear mechanism 60 driven by a motor 50 between the ligh...

Abstract

The invention relates to the technical field of lighting fixtures, in particular to a light spot regulating method of a shadowless lamp. The light spot regulating method comprises the following steps that: a tact switch on a handle is rotated so as to switch on a master control module; the master control module transmits a motor rotation signal to each individual motor control module; the individual motor control modules switch on corresponding motors to rotate; and the motors drive worm gear mechanisms to rotate to enable corresponding light source modules to rotate around support shafts so as to regulate light emergent angles. By utilizing the method, on the one hand, the light emergent angle of each light source module can be regulated through rotating the handle, and on the other hand, the light emergent angle of each light source module also can be regulated through external operation boxes, thus double use functions are achieved, and a user can conveniently select one of modes according to use convenience. Therefore, the method provided by the invention has the advantages of humanized design and better practicability.

Description

technical field [0001] The invention relates to the technical field of lighting fixtures, in particular to a light spot adjustment method 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...
